Long-term follow-up after the treatment of impacted canines in the maxilla causing severe root resorption of the lateral incisors: two case reports. BMC Oral Health 2024; 24:482. [PMID: 38643143 PMCID: PMC11032590 DOI: 10.1186/s12903-024-04275-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Accepted: 04/18/2024] [Indexed: 04/22/2024] Open
Abstract
BACKGROUND Root resorption of adjacent teeth due to impacted canines is common, and orthodontic treatment often leads to secondary resorption or even loss of adjacent roots. Clinical reports of long-term stability after treatment are rare. CASE PRESENTATION This study reports two cases of maxillary impacted canines resulting in severe root resorption of the adjacent lateral incisors. Surgical exposure, orthodontic retraction, and alignment of the impacted canines were successful in both cases, and the resorbed lateral incisors were stable with no significant loosening and normal pulp vitality after treatment and at the 5- and 10-year follow-up appointments. CONCLUSIONS Light orthodontic force may be used to move adjacent teeth with root resorption due to tooth obstruction. The path and direction in which the teeth are moved must be specifically designed so that the adjacent roots are not resorbed and so long-term stability can be achieved.

Abstract
Introduction The following bibliographic review was carried out with the purpose of recognizing the clinical and radiographic characteristics that must be considered in the diagnosis of external root resorption, including treatments. Methods A bibliographic search was carried out in PubMed/Medline, Cochrane Library and Google Scholar databases under the term "external root resorption", from 2010 to 2022 in Spanish and English. Experimental studies and bibliographic reviews were selected, and finally 17 articles were included. Results The results obtained indicated that each type of resorption presents specific clinical characteristics that differentiate them, these are: for external inflammatory resorption a negative pulp vitality; for replacement external resorption the absence of mobility and metallic percussion; for cervical external resorption a pink coloration of the crown; superficial external resorption does not present any type of clinical symptoms and transient apical collapse presents a transient change in color. Conclusion External root resorptions require accurate and early diagnosis. A clinical examination should be performed with emphasis on the following: probing, coloration, mobility, and vitality tests.

Abstract
The aetiology of impacted canines is multi-factorial. Several theories have been proposed, such as lack of space, genetic predisposition, physical barriers like supernumerary teeth, odontomas and other conditions that interfere with the eruption pathway. One of the main complications that can be generated by impacted canines is the resorption of the root of the adjacent teeth. This case report examines the importance of interdisciplinary management of maxillary incisors with root resorption caused by impacted canines in a 13-year-old male patient. Careful traction of impacted canines and proper tissue management followed by space closure and retroclination of anterior incisors with orthodontic treatment. Finally, functional and aesthetic results using dental veneers for oral rehabilitation allowed the patient to obtain favourable results.

Attenuation of orthodontically induced inflammatory root resorption by using low-intensity pulsed ultrasound as a therapeutic modality- a systematic review. BMC Oral Health 2024; 24:67. [PMID: 38200481 PMCID: PMC10782536 DOI: 10.1186/s12903-023-03741-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Accepted: 12/06/2023] [Indexed: 01/12/2024] Open
Abstract
Ultrasound is an effective tool for both diagnostic and therapeutic applications. As an imaging tool, ultrasound has mostly been used for real-time noninvasive diagnostic imaging. As ultrasound propagates through a material, a reflected radio-frequency (RF) signal is generated when encountering a mismatch in acoustic impedance. While traditionally recognized for its diagnostic imaging capabilities, the application of ultrasound has broadened to encompass therapeutic interventions, most notably in the form of Low-Intensity Pulsed Ultrasound (LIPUS). Low-Intensity Pulsed Ultrasound (LIPUS) is a form of mechanical energy transmitted transcutaneously by high-frequency acoustic pressure waves. The intensity of LIPUS (30 mW/cm2) is within the range of ultrasound intensities used for diagnostic purposes (1-50 mW/cm2) and is regarded as non-thermal, non-destructive, permeating living tissues and triggering a cascade of biochemical responses at the cellular level. The LIPUS device produces a 200 µs burst of 1.5 MHz acoustic sine waves, that repeats at a modulation frequency of 1 kHz and provides a peak pressure of 30 mW/cm2. Low-intensity pulsed ultrasound (LIPUS) forms one of the currently available non-invasive healing-enhancing devices besides electro-stimulation (pulsed electro-magnetic field, PEMF). This modality has been leveraged to enhance drug delivery, expedite injury recovery, improve muscle mobility, alleviate joint stiffness and muscle pain, and enhance bone fracture healing. Although LIPUS has been embraced within various medical disciplines, its integration into standard dental practices is still in its nascent stages, signifying an unexplored frontier with potentially transformative implications. Low-intensity pulsed ultrasound (LIPUS) has emerged as an attractive adjuvant therapy in various dental procedures, such as orthodontic treatment and maxillary sinus augmentation. Its appeal lies in its simplicity and non-invasive nature, positioning LIPUS as a promising avenue for clinical innovation. One particular area of interest is orthodontically induced inflammatory root resorption (OIIRR), an oftenunavoidable outcome of the orthodontic intervention, resulting in the permanent loss of root structure. Notably, OIIRR is the second most common form of root resorption (RR), surpassed only by root resorption related to pulpal infection. Given the high prevalence and potential long-term consequences of OIIRR, this literature review seeks to evaluate the efficacy of LIPUS as a therapeutic approach, with an emphasis on assessing its capacity to reduce the severity of OIIRR to a level of clinical significance. To conduct this systematic review, a comprehensive automated literature search was executed across multiple databases, including MEDLINE, Embase, PsycINFO, Web of Knowledge, Scopus, CINAHL, LILACS, SciELO, Cochrane, PubMed, trials registries, 3ie, and Google Scholar. Both forward and backward citation tracking was employed, encompassing studies published from database inception through January 2009 to April 2023. The review focused on randomized controlled trials (RCTs) that specifically evaluated the effects of low-intensity pulsed ultrasound therapy on orthodontically induced inflammatory root resorption (OIIRR), without restrictions of publication date. A stringent selection criterion was applied, and only studies demonstrating high levels of statistical significance were included. Ultimately, fourteen studies met the inclusion criteria and were subjected to further analysis. The overall quality of the included randomized controlled trials (RCTs) was rigorously assessed utilizing the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. This analysis revealed certain methodological limitations that posed challenges in drawing definitive conclusions from the available evidence. Despite these constraints, the review offers invaluable insights that can inform and guide future research. Specifically, it delineates recommendations for targeted populations, necessary interventions, appropriate outcome measures, suitable study designs, and essential infrastructure to facilitate further investigations. The synthesis of these insights aims to enhance the development and application of low-intensity pulsed ultrasound therapy within the field of dentistry, thereby contributing to improved patient outcomes.

Abstract
AIM To evaluate the impact of cone beam computed tomography (CBCT) on treatment planning for impacted maxillary canines; secondly, to identify CBCT factors influencing a change in the treatment plan; and thirdly, to assess 2D radiographic factors that can aid in selecting appropriate candidates for CBCT. MATERIAL AND METHODS Patients with impacted maxillary canines and an overlap of a neighboring tooth in 2D radiographs and the suspicion of root resorption were referred for CBCT examination. An initial treatment plan was based on 2D radiographs, and the final treatment plan was established after the CBCT examination. Logistic regression analyses and t-tests were performed to evaluate differences in radiographic findings between the groups with and without a change in treatment plan. RESULTS The study prospectively included 125 impacted canines, and 43 (34.4%) of them had a change in treatment plan after the CBCT examination. The most common change was a modification in the direction of cantilever traction (n = 28; 22.4%), while the least common was the change in decision to remove/keep the canine (n = 4; 3.2%). The size of the alpha and lateral angles had a significant impact on the decision to change the treatment plan. Other radiographic findings did not influence a change in treatment plan. CONCLUSIONS One-third of the canines had a change in treatment plan after supplemental CBCT examination. Canines with large alpha and lateral angles measured in the panoramic image were found to be significantly more likely to undergo changes in the initial direction of cantilever traction or changes to the canine extraction strategy following CBCT examination.

Long-term prognosis after decoronation of avulsed teeth with replacement resorption: a report of three cases. J Clin Pediatr Dent 2024; 48:204-211. [PMID: 38239174 DOI: 10.22514/jocpd.2024.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Accepted: 03/01/2023] [Indexed: 01/23/2024] Open
Abstract
The complications of replacement resorption following tooth injury in growing children include infrapositioning of the tooth, tilting of the adjacent teeth, and alveolar ridge deformity. Decoronation is a conservative treatment method that facilitates bone preservation. The current case report focuses on the long-term preservation of alveolar ridge dimension following decoronation in three patients. Decoronation was performed prior to occurrence of the pubertal growth spurt, and the patients' ridge width and vertical apposition were monitored for at least 4 years. Timely intervention and regular monitoring are essential for maximization of the benefits of decoronation, a simple procedure that preserves esthetics and minimizes the need for further treatments. The importance of space management for prosthetic treatment has also been highlighted. The findings of this study show that infrapositioned teeth in growing children can be treated successfully using decoronation.

Abstract
Objective To investigate the effect of human subcutaneous adipose-derived stem cells (hADSCs) local transplantation on orthodontically induced root resorption (OIRR) and provide theoretical and experimental basis for the clinical application of hADSCs to inhibit OIRR. Methods Forty 8-week-old male Sprague Dawley rats were randomly divided into experimental group and control group, with 20 rats in each group, to establish the first molar mesial orthodontic tooth movement (OTM) model of rat right maxillary. The rats in the experimental group were injected with 25 μL of cell suspension containing 2.5×10 5 hADSCs on the 1st, 4th, 8th, and 12th day of modeling, while the rats in the control group were injected with 25 μL of PBS. The rat maxillary models were obtained before and after 7 and 14 days of force application, and 10 rats in each group were killed and sampled after 7 and 14 days of force application. The OTM distance was measured by stereomicroscope, the root morphology of the pressure side was observed by scanning electron microscope and the root resorption area ratio was measured. The root resorption and periodontal tissue remodeling of the pressure side were observed by HE staining and the root resorption index was calculated. The number of cementoclast and osteoclast in the periodontal tissue on the pressure side was counted by tartrate resistant acid phosphatase staining. Results The TOM distance of both groups increased with the extension of the force application time, and there was no significant difference ( P<0.05). There was no significant difference in OTM distance between the experimental group and the control group after 7 and 14 days of force application ( P>0.05). Scanning electron microscope observation showed that small and shallow scattered resorption lacunae were observed on the root surface of the experimental group and the control group after 7 days of force application, and there was no significant difference in the root resorption area ratio between the two groups ( P>0.05); after 14 days of application, the root resorption lacunae deepened and became larger in both groups, and the root resorption area ratio in the experimental group was significantly lower than that in the control group ( P<0.05). The range and depth of root absorption in the experimental group were smaller and shallower than those in the control group, and the root absorption index in the experimental group was significantly lower than that in the control group after 14 days of force application ( P<0.05). The number of cementoclast in the experimental group was significantly lower than that in the control group after 7 and 14 days of force application ( P<0.05); the number of osteoclasts in the experimental group was significantly lower than that in the control group after 14 days of force application ( P<0.05). Conclusion Local transplantation of hADSCs may reduce the area and depth of root resorption by reducing the number of cementoclasts and osteoclasts during OTM in rats, thereby inhibiting orthodontic-derived root resorption.

Abstract
This review investigated whether any therapeutic options influenced the outcome of treatment for teeth with external cervical resorption. Out of 870 articles identified by an electronic search, 60 clinical case reports and six case series were included. No randomised clinical trials were found. Risk of bias was assessed using Joanna Briggs Institute's tools. External surgical intervention was the preferred method of accessing the lesions. Removal of resorptive tissue was most often achieved mechanically. Bioactive endodontic cements were the preferred materials for restoring teeth. The outcome measures were based on clinical and radiographic parameters. Of the cases included in the review, no specific treatment approach had a superior outcome in relation to Heithersay's classification. Furthermore, due to the absence of randomised clinical trials, and the low level of evidence associated with case reports/case series, it was not possible to define the optimum clinical treatment for external cervical resorption.

Orthodontic Treatment of Palatally Impacted Canines in Severe Non-Syndromic Oligodontia with the Use of Mini-Implants: A Case Report. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:2032. [PMID: 38004081 PMCID: PMC10673481 DOI: 10.3390/medicina59112032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/22/2023] [Revised: 11/10/2023] [Accepted: 11/14/2023] [Indexed: 11/26/2023]
Abstract
Background: The risk of palatally displaced canines (PDCs) rises in patients with tooth agenesis. The orthodontic extrusion and alignment of PDCs require adequate anchorage to enable tooth movement and control the side effects. There is no paper presenting treatment in the case of severe oligodontia with simultaneous PDCs and the use of mini-implants (MIs) for their orthodontic extrusion. Case presentation: A 15-year-old patient presented with non-syndromic oligodontia and bilateral PDCs. Cone beam computed tomography revealed that both PDCs were in proximity to the upper incisors' roots. There was no evident external root resorption of the incisors. The "canines first" approach was chosen. MIs were used both as direct and indirect anchorage. First, the extrusive forces of cantilevers were directed both occlusally and distally. Next, the buccal directions of forces were implemented. Finally, fixed appliances were used. PDCs were extruded, aligned, and torqued. Proper alignment and occlusion were achieved to enable further prosthodontic restorations. Conclusions: The use of MIs made it possible to avoid collateral effects, reduce the risk of complications, and treat the patient effectively. MIs provide adequate anchorage in demanding cases. The use of MIs for the extrusion of PDCs made it possible to offer this treatment option to patients with severe oligodontia. The presented protocol was effective and served to circumvent treatment limitations associated with an inadequate amount of dental anchorage and a high risk of root resorption.

Photobiomodulation therapy assisted orthodontic tooth movement: potential implications, challenges, and new perspectives. J Zhejiang Univ Sci B 2023; 24:957-973.

Abstract
Over the past decade, dramatic progress has been made in dental research areas involving laser therapy. The photobiomodulatory effect of laser light regulates the behavior of periodontal tissues and promotes damaged tissues to heal faster. Additionally, photobiomodulation therapy (PBMT), a non-invasive treatment, when applied in orthodontics, contributes to alleviating pain and reducing inflammation induced by orthodontic forces, along with improving tissue healing processes. Moreover, PBMT is attracting more attention as a possible approach to prevent the incidence of orthodontically induced inflammatory root resorption (OIIRR) during orthodontic treatment (OT) due to its capacity to modulate inflammatory, apoptotic, and anti-antioxidant responses. However, a systematic review revealed that PBMT has only a moderate grade of evidence-based effectiveness during orthodontic tooth movement (OTM) in relation to OIIRR, casting doubt on its beneficial effects. In PBMT-assisted orthodontics, delivering sufficient energy to the tooth root to achieve optimal stimulation is challenging due to the exponential attenuation of light penetration in periodontal tissues. The penetration of light to the root surface is another crucial unknown factor. Both the penetration depth and distribution of light in periodontal tissues are unknown. Thus, advanced approaches specific to orthodontic application of PBMT need to be established to overcome these limitations. This review explores possibilities for improving the application and effectiveness of PBMT during OTM. The aim was to investigate the current evidence related to the underlying mechanisms of action of PBMT on various periodontal tissues and cells, with a special focus on immunomodulatory effects during OTM.

Abstract
OBJECTIVES External cervical root resorption (ECR) is a poorly understood and aggressive form of resorption. The purpose of this study was to examine the prevalence, characteristics, and risk factors associated with the occurrence of ECR in patients seeking endodontic care from private practice settings. MATERIALS AND METHODS Records of 343 patients with 390 teeth diagnosed with ECR were identified from 3 private endodontic practices from 2008 to 2022. The patients' demographic information, systemic conditions, and dental history were recorded. The characteristics of the cases including Heithersay classification, pulpal and periapical status, and their management were documented. The association between case severity and potential predisposing factors was examined using chi-square analysis. RESULTS The overall prevalence of ECR among patients seeking endodontic care was low (< 1%). However, there was a greater than twofold increase in the pooled prevalence from 2016 to 2021 (0.99%) compared to the data from 2010 to 2015 (0.46%). The most commonly affected teeth were anterior teeth (48.7%). Class II (30.0%) and class III (45.4%) defects were the most often identified. Patients with a history of trauma or orthodontic treatment were significantly more likely to be diagnosed with severe cervical resorption (class III or IV) (p < 0.05). CONCLUSIONS There has been an increase in the prevalence of ECR in patients seeking endodontic care. A history of orthodontic treatment and traumatic dental mechanical injuries may predict the severity of resorption. CLINICAL RELEVANCE The upward trend in the occurrence of ECR warrants close monitoring of the patients at high risk of developing the condition to facilitate early detection and management.

Abstract
The current literature on multiple idiopathic cervical root resorption (MICRR), a rare and aggressive form of external root resorption, is limited to case reports and series. Therefore, we performed a systematic review of this condition. A comprehensive search of PubMed, Embase, Web of science, Cochrane Library, CNKI, and WANFANG was conducted using key terms relevant to MICRR, supplemented by a grey literature search. Risk of bias was assessed using Cochrane's and Joanna Briggs Institute's tools. A total of 36 studies with 47 cases were included. MICRR is more common among younger females and may be related to hormonal changes and denosumab use. Initially, the premolars are usually affected but all permanent teeth may eventually be involved. Cone-beam computed tomography is recommended for diagnosis and assessment of resorptive lesions. The management is focused on complete removal and restoration of the resorptive tissue to maintain the tooth's structural integrity. However, MICRR usually has a poor prognosis. Due to its invasive and aggressive behavior, MICRR requires greater attention.

Abstract
Objective: To evaluate the effectiveness of a minimally-invasive corticotomy-assisted treatment of palatally impacted canines (PICs) compared with the traditional method by evaluating treatment time, the velocity of movement, and the associated dentoalveolar changes. Materials and methods: Forty-six patients with palatally or mid-alveolar upper impacted canines were recruited and distributed into two groups: the corticotomy-assisted traction group (CAT group, mean age: 20.39±2.27 years) and the traditional treatment group (TT group, mean age: 20.26±2.17 years). The closed surgical approach was used in both study groups. The velocity of traction movement, traction duration and overall treatment duration were evaluated clinically. In addition, the bone support ratios and the amount of root resorption were assessed on cone-beam computed tomography (CBCT) images. Results: At the end of treatment, significant differences were found between the two groups regarding the velocity of traction movement, traction time, and overall treatment time (P<0.05). The mean velocity of traction movement in the CAT group was greater than the TT group ( x velocity=1.15±0.35 mm/month; 0.70±0.33 mm/month, P=0.027, respectively). The duration of the active traction and the overall orthodontic treatment in the CAT group were significantly shorter than the TT group by 36% and 29%, respectively. The mean bone support ratios of the aligned canines did not differ significantly between the two groups (88% vs. 89% in the CAT and TT groups, respectively). No significant differences were found between the two groups regarding the mean amount of root resorption on the adjacent laterals ( x resorption = 1.30±1.18 mm; 1.22±1.02 mm, P=0.612, in CAT and TT groups, respectively). Conclusions: The traction movement velocity of the palatally impacted canines can be increased using minimally-invasive corticotomy-assisted orthodontic treatment. The side effects of the acceleration procedure were minimal and almost similar to those of the traditional technique.

Abstract
The literature is replete with articles describing the many and varied interactions between endodontic treatment and orthodontic tooth movement (OTM), often reporting conflicting views and findings, which creates confusion for clinicians. Original research and review articles have described aspects such as apical root resorption and potential pulpal complications of teeth related to OTM. Some interactions are of relatively minor clinical significance, whilst others may have adverse consequences. A history of dental trauma before or during OTM further complicates the interactions. This review re-assesses the historical literature on endodontic-orthodontic interactions in light of more recent research and presents guidelines for managing clinical situations involving both disciplines. © 2023 Australian Dental Association.

Regenerative Endodontic Procedures in Teeth with Root Resorption: A Systematic Review. Eur Endod J 2023; 8:170-186. [PMID: 37257034 PMCID: PMC10244915 DOI: 10.14744/eej.2023.77486] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 02/21/2023] [Accepted: 03/14/2023] [Indexed: 04/09/2023] Open
Abstract
The purpose of this systematic review was to critically evaluate the available clinical literature on the use of regenerative endodontic therapy (RET) for the treatment of root resorption. All case reports, case series and clinical studies documenting the management of root resorption in mature or immature permanent teeth using RET were included. Review articles, animal studies, and RET in teeth showing developmental anomalies were excluded. A literature search was conducted in electronic databases MEDLINE, Scopus, Cochrane, and Google Scholar from 2001 to January 2022. The JBI Critical Appraisal Checklist Quality was used to appraise the included case reports and case series. The Methodological item for non-randomised studies (MINORS) tool was used to appraise the clinical study critically. After applying the inclusion and exclusion criteria, the search resulted in 14 studies (12 case reports, 1 case series, and 1 clinical study) accounting for root resorption in 34 teeth from 29 patients treated with RET. Despite the wide variation in RET protocols, the arrest of root resorption and resolution of symptoms was seen in all teeth except one (failure after 27 months). The clinical study's cone beam computed tomography (CBCT) imaging evalu- ation documented a significant volumetric decrease in resorptive and periapical lesions after RET. The clinical study was deemed as good quality using the MINORS scale. The JBI critical appraisal tool showed that the case series was of poor quality; 11 of the case reports were of good quality, while 1 case report was of fair quality. This systematic review revealed a low-to-moderate level of evidence for the use of RET in resorption cases. However, further well-designed, long-term clinical studies are required to recommend it as an alternative treatment option for root resorption management. Funding: None. The systematic review was registered in PROSPERO (CRD42021274569). (EEJ-2022-11-136).

Abstract
THE AIM OF THE STUDY Was to compare the efficacy of various treatment options for external inflammatory root resorption according to literature data. MATERIALS AND METHODS Literature was searched in electronic databases «eLibrary» and «PubMed» for key words «external inflammatory resorption treatment», «external inflammatory resorption management». Inclusion criteria comprised publications in Russian or English, clinical and experimental studies, full description of treatment protocol and obtained results. Studies with no full text, describing root resorption of orthodontic origin, clinical cases and clinical case series were excluded from the study. RESULTS The problem of external inflammatory root resorption is poorly described in the Russian scientific literature. There are no registered protocols for its prevention and treatment or therapeutic agents with proved efficacy available in Russia. The only accessible approach for external inflammatory root resorption remains timely pulp extirpation after dental trauma which importance is underlined by all authors involved in the field of dental trauma studies. MTA and calcium hydroxide being popular as intracanal medications still have significant inconveniences as they potentially provoke root dentine fractures or replacement resorption. CONCLUSION There is a need for elaboration and implementation of new prevention and treatment options for external inflammatory root resorption after dental trauma.

Abstract
Cervical root resorption is a rare destructive disease that originates from the external cervical root surface. It has a multifactorial etiology. Cervical root resorption may affect several teeth and its treatment can be complicated due to the size, location, and extension of the resorptive defect. Rheumatoid arthritis is a chronic inflammatory autoimmune disease that has systemic effects. The objective of this article was to report a rare case of multiple idiopathic cervical resorptions in a patient with rheumatoid arthritis. A 52-year-old male patient with a 20-year history of rheumatoid arthritis was diagnosed with multiple idiopathic cervical resorptions through cone-beam computed tomography (CBCT) and clinical examination. All known causes for cervical resorption were ruled out after a detailed anamnesis. This report details inflammation due to rheumatoid arthritis as a possible cause of idiopathic cervical resorption. The systemic alterations wrought by rheumatoid arthritis could be related to the etiopathogenesis of cervical root resorption. Non-surgical endodontic treatment was done for the maxillary left canine. The defect was surgically repaired using bioceramic putty. The 12-month recall revealed the good healing of the periodontal and periradicular conditions with no obvious clinical symptoms. At the 36-month recall visit, clinical and radiographic evidence of deterioration in the repair material was observed. At the 54-month follow-up, deterioration of repair material was observed with an increase in the extension of resorption in tooth 14 was detected. Reasons for this deterioration remain unclear. Ruling out all other factors for cervical root resorption, how rheumatoid arthritis contributes to cervical root resorption is still lacking/unclear. Dental care providers must be vigilant for signs of cervical root resorption in vulnerable patients with rheumatoid arthritis for early diagnosis and prompt treatment. Keywords: External root resorption, Inflammatory markers, Multiple root resorption, Rheumatoid arthritis, Resorption repair.

Traumatized teeth: clinical practice guideline for the interim management of teeth with various poor prognosis scenarios in growing patients. QUINTESSENCE INTERNATIONAL (BERLIN, GERMANY : 1985) 2022; 53:722-731.

Abstract
OBJECTIVES Many treatment options accepted for unsalvageable traumatized teeth in adults would seem contraindicated in children and adolescents. Instead, growing patients need interim restorative measures, thus extensively preserving their local bone and soft tissue structures and, ideally, preparing the involved site for later definitive restoration while they transform to skeletal maturity. This narrative topic review addresses the interim management in case of very deep intra-extra-alveolar fractures, extensive infection-related root resorption, tooth ankylosis, and anterior tooth loss in growing patients, and seeks to empower the clinician to select the appropriate treatment approach. DATA SOURCES The literature up to 2021 was reviewed based on several scoping searches on PubMed and the Cochrane Library using relevant terms. Due to the complexity of the topic (with various poor prognosis scenarios and the differing therapeutic options), a systematic review was deemed inappropriate. CONCLUSION Suitable interim treatment options include extrusion of teeth showing deep intra-extra-alveolar fractures, and decoronation of ankylosed teeth as well as resin-bonded fixed dental prostheses, natural tooth pontics, and primary tooth autotransplantations after tooth loss. The interim management options described in this article represent compromises chosen in the absence of better alternatives after a careful risk-benefit analysis. However, if adequately performed, the presented treatment options have the potential to achieve the temporary restoration of function and esthetics in growing patients. Close clinical and (if appropriate) radiologic monitoring of these patients is considered mandatory to ensure early detection of possible complications that might jeopardize or could render impossible subsequent therapeutic measures.

Abstract
External cervical tooth root resorption is one of the most aggressive types of pathological resorption. Due to the uncontrolled growth of resorptive tissue, irreversible loss of dentin and cement occurs. To date, there is no common position regarding the etiological factor and pathogenesis of invasive cervical resorption. The histological picture is similar to some fibro-bone lesions. The treatment outcome of the pathology is difficult to predict because elimination of the causative factor is often not sufficient for resorption arrest. Only the complete elimination of resorptive tissue helps to stop the process. The report describes a clinical case of a successful treatment of invasive cervical resorption of dental hard tissues.

Management of internal inflammatory root resorption using injectable platelet-rich fibrin revascularization technique: a clinical study with cone-beam computed tomography evaluation. Clin Oral Investig 2021; 26:1505-1516.

Abstract
OBJECTIVES The current study evaluated clinically and radiographically the management of internal inflammatory root resorption (IIRR) in permanent anterior teeth with or without periapical lesions using injectable platelet-rich fibrin (i-PRF) regenerative approach. METHODS Ten systemically healthy patients, with thirteen anterior mature teeth diagnosed with IIRR were selected for the study. At the first visit, the tooth was anesthetized, access cavity opened, root canals were mechanically prepared then medicated with calcium hydroxide and temporarily sealed. After 2-4 weeks, regenerative endodontic procedures were performed by preparing and applying i-PRF inside the canal, then a freshly prepared PRF membrane was placed over it. White mineral trioxide aggregate was placed over the PRF matrix, and the tooth was restored with a glass ionomer cement base and resin composite restoration. The patients were recalled for clinical and radiographic evaluation and follow-up every 3 months for 12 months. Cone-beam computed tomography (CBCT) imaging was performed preoperatively and after 12 months. RESULTS Clinical evaluation results showed resolution of signs and symptoms through the follow-up period in all of the cases. Both CBCT imaging readings of IIRR lesions and periapical lesions revealed a volumetric significant difference (p = 0.00) between the preoperative and the 12-month follow-up period. CONCLUSIONS Usage of i-PRF could arrest and allow for healing of IIRR in permanent mature teeth and allow for periapical healing with successful clinical results. CLINICAL RELEVANCE i-PRF revascularization technique proved to be a successful REP in the treatment of the IIRR, reducing the number of appointments and increasing patient compliance.

Abstract
External root resorption (ERR) is a silent destructive phenomenon detrimental to dental health. ERR may have multiple etiologies such as infection, inflammation, traumatic injuries, pressure, mechanical stimulations, neoplastic conditions, systemic disorders, or idiopathic causes. Often, if undiagnosed and untreated, ERR can lead to the loss of the tooth or multiple teeth. Traditionally, clinicians have relied on radiographs and cone beam computed tomography (CBCT) images for the diagnosis of ERR; however, these techniques are not often precise or definitive and may require exposure of patients to more ionizing radiation than necessary. To overcome these shortcomings, there is an immense need to develop non-invasive approaches such as biomarker screening methods for rapid and precise diagnosis for ERR. In this review, we performed a literature survey for potential salivary or gingival crevicular fluid (GCF) proteomic biomarkers associated with ERR and analyzed the potential pathways leading to ERR. To the best of our knowledge, this is the first proteomics biomarker survey that connects ERR to body biofluids which represents a novel approach to diagnose and even monitor treatment progress for ERR.

Abstract
AIM This report presents a case of external cervical resorption and illustrates the effects of a non-surgical approach in the amelioration of this condition and discusses the etiology, classifications, and treatment options. BACKGROUND One of the most common root resorption forms is external cervical resorption, which initiates in the cervical area of the tooth and spreads out in the thickness of the dentin in an irregular way. This resorptive process may spread across the dentin leading to significant loss of tooth structure, with or without pulp involvement. CASE DESCRIPTION During a routine radiographic examination of a 25-year-old female patient, external cervical resorption in a maxillary right second premolar was discovered. Cone-beam computed tomography (CBCT) confirmed the extension of the lesion into the pulp and the need for root canal treatment. The defect was sealed with bioceramic putty. One year CBCT follow-up demonstrated the cessation of the resorption site with no clinical symptoms. CONCLUSION CBCT examination and combining non-surgical root canal treatment with non-surgical repair using bioceramic putty was an effective treatment option. CLINICAL SIGNIFICANCE Treatment selection of external cervical resorption depends on many factors, including the location and severity of the resorptive defect and the remaining tooth structure. If the resorptive defect has extended to the pulp, the management involves root canal treatment and subsequent placement of a direct restoration to restore the resorptive lesion.

Is Inflammation a Friend or Foe for Orthodontic Treatment?: Inflammation in Orthodontically Induced Inflammatory Root Resorption and Accelerating Tooth Movement. Int J Mol Sci 2021; 22:2388. [PMID: 33673606 PMCID: PMC7957544 DOI: 10.3390/ijms22052388] [Citation(s) in RCA: 45] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2021] [Revised: 02/20/2021] [Accepted: 02/22/2021] [Indexed: 02/07/2023] Open
Abstract
The aim of this paper is to provide a review on the role of inflammation in orthodontically induced inflammatory root resorption (OIIRR) and accelerating orthodontic tooth movement (AOTM) in orthodontic treatment. Orthodontic tooth movement (OTM) is stimulated by remodeling of the periodontal ligament (PDL) and alveolar bone. These remodeling activities and tooth displacement are involved in the occurrence of an inflammatory process in the periodontium, in response to orthodontic forces. Inflammatory mediators such as prostaglandins (PGs), interleukins (Ils; IL-1, -6, -17), the tumor necrosis factor (TNF)-α superfamily, and receptor activator of nuclear factor (RANK)/RANK ligand (RANKL)/osteoprotegerin (OPG) are increased in the PDL during OTM. OIIRR is one of the accidental symptoms, and inflammatory mediators have been detected in resorbed roots, PDL, and alveolar bone exposed to heavy orthodontic force. Therefore, these inflammatory mediators are involved with the occurrence of OIIRR during orthodontic tooth movement. On the contrary, regional accelerating phenomenon (RAP) occurs after fractures and surgery such as osteotomies or bone grafting, and bone healing is accelerated by increasing osteoclasts and osteoblasts. Recently, tooth movement after surgical procedures such as corticotomy, corticision, piezocision, and micro-osteoperforation might be accelerated by RAP, which increases the bone metabolism. Therefore, inflammation may be involved in accelerated OTM (AOTM). The knowledge of inflammation during orthodontic treatment could be used in preventing OIIRR and AOTM.

Abstract
AIM The objective of this case report was to present a rare case of simultaneous multiple internal root resorption (IRR) in four mandibular incisors and discuss the possible etiology and suitable armamentarium for its treatment based on different morphological considerations. BACKGROUND IRR in permanent dentition is a rare pathological condition and its etiology is not yet fully understood. Very few cases of multiple IRR were reported. This is the first reported case of multiple IRR due to traumatic injury. CASE DESCRIPTION A 23-year-old man suffered trauma to his mandible after falling from a trampoline. His mandibular incisors suffered subluxation injuries and his orthodontic fixed retainer got detached. He delayed treatment and visited our clinic 4.5 months after the incident. Clinical and radiographic examination revealed four mandibular incisors with almost identical IRR defects at the apical third of the roots. The patient was then treated with four non-surgical root canal treatments using various endodontic instruments and techniques. Fifteen-month post-trauma, he showed no evidence of pathology at the follow-up examination. CONCLUSION Delayed treatment of dental trauma might cause multiple IRR, and the presence of an orthodontic fixed retainer can distribute surface forces and result in uniform IRR defects. CLINICAL SIGNIFICANCE The combination of the self-adjusting file (SAF) and the XP-endo finisher is recommended for chemomechanical preparation of IRR defects in oval canals, especially at the apical third.

Polymorphisms of Encoding Genes IL1RN and P2RX7 in Apical Root Resorption in Patients after Orthodontic Treatment. Int J Mol Sci 2021; 22:ijms22020777.

Abstract
External apical root resorption (EARR) is one of the most serious complications associated with orthodontic treatment. The aim of the study was to analyze the relationships between selected single nucleotide polymorphisms (SNPs) in Interleukin 1 receptor antagonist (IL1RN), purinoreceptor P2X7 (P2RX7) and EARR in patients after orthodontic treatment. The study comprised 101 patients who underwent a complex orthodontic treatment with a combination of fixed appliances. Roots were measured based on orthopantomograms and lateral cephalometric radiographs taken before and at the end of the treatment using diagnostic software. Proportional measurements of selected teeth were made using the modified Linge and Linge methods. Based on the presence or absence of EARR, patients were divided into two groups: control group, 61 patients without EARR (with 0.90 ≤ rRCR ≤ 1.00), and EARR group, 40 patients with EARR (rRCR < 0.90). Root resorption in selected groups was also evaluated with the scores of Malmgren and Levander. SNP analysis was performed using the real-time polymerase chain reaction (PCR) method. The analysis indicated that a specific haplotype of P2RX7 (rs208294) and IL1RN (rs419598) modified the risk of EARR development (p < 0.05), with a Bonferroni correction. The analysis of the P2RX7 and IL1RN gene polymorphisms showed that the presence of SNPs of these genes may predispose individuals to EARR. These findings indicate that EARR is a complex condition influenced not only by environmental factors and needs further study on the genetic risk factors.

Abstract
Purpose: To present an evidence-based guideline for non-vital pulp therapies due to deep caries or trauma in primary teeth. Methods: The authors, working with the American Academy of Pediatric Dentistry, conducted a systematic review/meta-analysis for studies on non-vital primary teeth resulting from trauma or caries and used the GRADE approach to assess level of certainty of evidence for clinical recommendations. Results: GRADE was assessed from high to very low. Comparing teeth with/without root resorption, pulpectomy success was better (P<0.001) in those without preoperative root resorption. Zinc oxide plus iodoform plus calcium hydroxide ([ZO/iodoform/CH]; Endoflas TM ) and zinc oxide and eugenol (ZOE) pulpectomy success did not differ from iodoform (iodoform plus calcium hydroxide; VitapexTM, MetapexTM) (P=0.55) after 18-months; however, ZO/iodoform/CH and ZOE success rates remained near 90 percent while iodoform was 71 percent or less. Network analysis ratings showed ZO/iodoform/CH and ZOE better than iodoform. Lesion sterilization tissue repair (LSTR) was better (P<0.001) than pulpectomy in teeth with preoperative root resorption, but pulpectomy results were better (P=0.09) if roots were intact. Rotary instrumentation of root canals was significantly faster (P<0.001) than manual, but the quality of fill did not differ (P=0.09) and both had comparable success. Network analysis ranked ZO/iodoform/CH the best, ZOE second, and iodoform lowest at 18 months. Success rates were not impacted by method of obturation or root length determination, type of tooth, number of visits, irrigants, smear layer removal, or timing/type of final restoration. Conclusions: Pulpectomy 18-month success rates supported ZO/iodoform/CH and ZOE pulpectomy over iodoform. LSTR had limited indication for teeth with resorbed roots and requires close monitoring.

Abstract
OBJECTIVES To develop a clinical practice guideline on orthodontically induced external apical root resorption (EARR), with evidence-based and, when needed, consensus-based recommendations concerning diagnosis, risk factors, management during treatment, and after-treatment care. MATERIALS AND METHODS The Appraisal of Guidelines for Research and Evaluation II instrument and the Dutch Method for Evidence-Based Guideline Development were used to develop the guideline. Based on a survey of all Dutch orthodontists, we formulated four clinical questions regarding EARR. To address these questions, we conducted systematic literature searches in MEDLINE and Embase, and we performed a systematic literature review. The quality of evidence was assessed with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. After discussing the evidence, a Task Force formulated considerations and recommendations. The drafted guideline was sent for comments to all relevant stakeholders. RESULTS Eight studies were included. The quality of evidence (GRADE) was rated as low or very low. Only the patient-related risk factors, 'gender' and 'age', showed a moderate quality of evidence. The Task Force formulated 13 final recommendations concerning the detection of EARR, risk factors, EARR management during treatment, and after-treatment care when EARR has occurred. Stakeholder consultation resulted in 51 comments on the drafted guideline. After processing the comments, the final guideline was authorized by the Dutch Association of Orthodontists. The entire process took 3 years. LIMITATIONS The quality of the available evidence was mainly low, and patient-reported outcome measures were lacking. CONCLUSIONS/IMPLICATIONS This clinical practice guideline allows clinicians to respond to EARR based on current knowledge, although the recommendations are weak due to low-quality evidence. It may reduce variation between practices and aid in providing patients appropriate information.

Abstract
Ankylotic root resorption is a serious complication following traumatic dental injuries. The aetiology of root resorption includes acute injury to the cementum and periodontal ligament, and subsequent biological processes that propagate the harm. The aim of the present paper is to present a structured treatment protocol for teeth that have experienced trauma and are at risk of developing ankylotic root resorption, followed by a decoronation protocol for situations in which ankylotic root resorption developed. This protocol provides a structured road map from the primary dental trauma, through the initial development of ankylosis detected radiographically, to the clinical manifestation that results in significant infra-occlusion. The current protocol integrates the best available evidence from the literature and from published guidelines. Ample contradictory data, which mainly consists of case reports related to the treatment of ankylotic root resorption, is available in the current literature. No accepted protocol or uniform guidelines for treatment in these cases exist, and many clinicians prefer avoiding replantation of an avulsed tooth that seems to have an uncertain longterm prognosis, or performing decoronation when infra-occlusion developed. As a result, young patients lose the benefits associated with replantation and decoronation procedures. The option of re-implantation of the avulsed teeth should be considered irrespective of the negative long-term prognosis. Following ankylosis development, the goal of submerging the tooth root (decoronation) is to maintain the horizontal dimension of the alveolar ridge and also to gain vertical dimension, allowing implant placement in the future.

Abstract
The aim of this case report is to describe the treatment of an 11-year-old boy who was referred to an endodontist for evaluation of external inflammatory root resorption in the distal apical third of the permanent maxillary left lateral incisor, caused by deviation in the eruption path of the permanent maxillary left canine. The results of the pulpal sensitivity test of the permanent maxillary left lateral incisor were inconclusive and similar to those for the homologous tooth, so the endodontist opted for a clinical and radiographic follow-up. The patient was referred to an orthodontist, who placed a fixed Haas-type palatal expander. After the eruption of all permanent teeth, the orthodontist placed a fixed orthodontic appliance. After approximately 3 years of monitoring, bone repair with dental remodeling was observed, and the results of a pulpal sensitivity test were positive. This case demonstrates that proper monitoring is critical in establishing the diagnosis and treatment plan and ultimately to the success of clinical management.

Abstract
INTRODUCTION Root resorptions are, with white spots, some of the inconveniences caused by orthodontic treatments. Although they are rare, they should not be ignored despite the many benefits gained by orthodontic treatment. Contrary to white spots, which are controllable by good dental hygiene, root resorptions can occur despite patient cooperation. Orthodontists should be aware of this phenomenon and make regular radiologic controls a priority for detection "before, during and after" treatment. MATERIAL AND METHOD After literary references, the presentation of the case report will illustrate the role of the orthodontist in the preservation and care of teeth damaged by impacted cuspids. DISCUSSION The discussion will focus on the prevention and the interception of those phenomena, the etiologic research on these cases, on medical supervision and prognostic for damaged teeth. CONCLUSION Before the conclusion, we will evoke the contribution of the cone-beam in the diagnosis of root resorption.

Intrusive luxation is a severe trauma-related event with a high frequency of pulp necrosis and root resorption. A common complication following intrusion is tooth ankylosis, which can extend to progressive replacement root resorption. An increasing infraposition in growing individuals can also occur. Decoronation is a new conservative treatment for cases of tooth ankylosis in young patients who have not finished growing. In this surgical technique, the tooth crown is removed and the root with replacement resorption process remains inside the alveolus. This treatment allows the alveolar bone to continue to develop, thus preserving bone dimensions. The purpose of this article is to report a multidisciplinary case of a young patient with anterior open bite, dental ankylosis, and tooth infraposition affected by intrusive luxation. Decoronation was the treatment of choice for this patient. The patient was then referred to orthodontic treatment to maintain the space of the maxillary right central incisor and open bite correction. After 5 years of follow-up, good clinical and radiologic results were obtained.

Idiopathic external apical root resorption: clinical report of 2 cases. GENERAL DENTISTRY 2017; 65:62-65. [PMID: 28253184] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/06/2023]
Abstract
External root resorptions are characterized by progressive destruction of hard tissue due to clastic activity. This article reports 2 cases that involved the nonsurgical treatment of mandibular molars with idiopathic external root resorption. In the first case, clinical and radiographic examination showed irreversible inflammation of the pulp tissue and resorption of the distal root. Chronic inflammatory infiltrate and necrosis were identified by histopathologic examination of the pulp tissue. In the second case, inadequate endodontic treatment and a resorptive process were observed in the mesial and distal roots. In both cases, mineral trioxide aggregate (MTA) was used as the filling material. Clinical and radiographic follow-ups of 1 and 7 years, respectively, showed a favorable trend, including interruption of the resorptive process and periradicular normality. More longitudinal studies are necessary to analyze the performance of MTA in treating external root resorptions.

Abstract
Invasive cervical resorption (ICR), a destructive form of external root resorption, is characterized by invasion of the fibrovascular tissue. This phenomenon is very rare and appears in 0.02% of the general population where the leading factors are orthodontics in addition to trauma, restorations, and bleaching. Heavy orthodontic force may increase the incidence to 1%. One of the main concerns regarding ICR is that it is often misdiagnosed with conventional diagnostic tools. In recent decades, a cone beam computed tomography (CBCT) imaging technique has become more common and can lead to a more accurate diagnosis and treatment plan. This case report describes a possible association between orthodontic treatment and ICR of a 14-year-old male, 18 months post orthodontic treatment. ICR in the mandibular right canine was diagnosed and verified by CBCT, and underwent combined endodontic-periodontal treatment. However, after orthodontic forced eruption was performed on this tooth to improve the bone defect, ICR was diagnosed on the mandibular right second premolar. The possible association between orthodontic treatment and ICR is discussed, as ICR was noted following orthodontic treatment on both occasions. This case report stresses the importance of ICR early detection by close attention to periodic radiographic checkups during orthodontic treatment. The use of modern diagnostic tools is highly recommended in suspicious cases. CONCLUSION A case is described in which the patient underwent two types of orthodontic treatment in the mandible at different time periods and developed ICR in two different teeth.

Abstract
The aim of this case report is to describe the treatment of a 9-year-old patient who suffered external root resorption of the permanent maxillary left lateral incisor following reimplantation of the avulsed left central and lateral incisors. Sixteen days after reimplantation and splinting of the incisors in a hospital emergency department, the patient was brought to the pediatric department of a dental school for further treatment. Root canal access was created in the maxillary left lateral and central incisors, and calcium hydroxide paste was used as intracanal dressing. At the 5-month follow-up, a radiograph revealed extensive external root resorption, a communicating root canal, and a periodontal lesion affecting the left lateral incisor. Management of the root resorption included obturation of the apical third of the canal with gutta percha and the middle third with mineral trioxide aggregate (MTA). At the 3-year recall examination, the patient was asymptomatic, and no mobility or soft tissue alterations were observed clinically. There was no radiographic sign that resorption had progressed. Despite the success of treatment, observation is still required. The use of MTA may be considered an alternative treatment for external root resorption after tooth reimplantation. The technique may allow tooth preservation in children until skeletal growth and development are completed and implant treatment may be considered.

Abstract
Root resorption is a condition resulting in the progressive loss of dental hard tissue. It may occur both within the root and upon the external aspect of the root. Diagnosis can be difficult and management challenging. Understanding the pathology is critical to understanding why and when this disease occurs and what the best management techniques involve. With such knowledge practitioners can confidently diagnose resorption, discuss prognoses and management strategies with the patient and either refer or begin treatment. Early intervention is paramount in improving outcomes. As such, if practitioners choose to refer patients they must be aware of what can be done immediately to mitigate risks until consultation and specialist treatment begins.

Effects of Low-Intensity Pulsed Ultrasound on Orthodontic Tooth Movement and Orthodontically Induced Inflammatory Root Resorption in Ovariectomized Osteoporotic Rats. ULTRASOUND IN MEDICINE & BIOLOGY 2016; 42:808-814.

Abstract
This study investigated the effects of low-intensity pulsed ultrasound (LIPUS) on orthodontic tooth movement (OTM) and orthodontically induced inflammatory root resorption (OIRR) in ovariectomized osteoporotic rats. Forty-eight 28-d-old female Wistar rats were divided into ovariectomized and intact groups. In both groups, animals were left untreated; treated with 50 g mesially directed orthodontic force on the maxillary first molars using nickel-titanium closed-coil springs for 28 d; or treated with the same orthodontic protocol along with a 20-min LIPUS application on alternate days for 28 d. Extent of OTM and amount of OIRR of mesial roots were measured on three-dimensionally reconstructed micro-computed tomography images. Ovariectomy increased OIRR (p < 0.05). LIPUS reduced root volumetric loss regardless of ovariectomy status (p < 0.05); only ovariectomized animals had decreased OTM (p < 0.05). LIPUS normalizes OTM and attenuates OIRR in ovariectomized osteoporotic rats. It may therefore be beneficial in women with postmenopausal osteoporosis.

Abstract
BACKGROUND External root resorption is a pathological process, which tends to occur following a wide range of mechanical or chemical stimuli such as infection, pressure, trauma or orthodontic tooth movement. Although it is predominantly detected by radiography, in some cases root resorption may be identified by clinical symptoms such as pain, swelling and mobility of the tooth. Treatment alternatives are case-dependent and aim to address the cause of the resorption and aid the regeneration of the resorptive lesion. OBJECTIVES To evaluate the effectiveness of any interventions that can be used in the management of external root resorption in permanent teeth. SEARCH METHODS The following electronic databases were searched: the Cochrane Oral Health Group Trials Register (to 14 October 2015), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2015, Issue 9), MEDLINE via OVID (1946 to 14 October 2015) and EMBASE via OVID (1980 to 14 October 2015). We searched the US National Institutes of Health Trials Register (http://clinicaltrials.gov) and the WHO Clinical Trials Registry Platform for ongoing trials. No restrictions were placed on the language or date of publication when searching the electronic databases. SELECTION CRITERIA We included randomised controlled trials of permanent teeth with any type of external root resorption, which has been confirmed by clinical and radiological examination, comparing one type of intervention (root canal medications and canal filling, splinting or extraction of teeth or the surgical removal of any relevant pathology) with another, or with placebo or no treatment. DATA COLLECTION AND ANALYSIS Two review authors screened search records independently. Full papers were obtained for potentially relevant trials. If data had been extracted, the statistical guidelines set out in the Cochrane Handbook would have been followed. MAIN RESULTS No randomised controlled trials that met the inclusion criteria were identified. However, we identified one ongoing study that is potentially relevant to this review and will be assessed when it is published. AUTHORS' CONCLUSIONS We were unable to identify any reports of randomised controlled trials regarding the efficacy of different interventions for the management of external root resorption. In view of the lack of reliable evidence on this topic, clinicians must decide on the most appropriate means of managing this condition according to their clinical experience with regard to patient-related factors. There is a need for well designed and conducted clinical trials on this topic, which conform to the CONSORT statement (www.consort-statement.org/).

Abstract
This case report describes the multidisciplinary management of a young male who presented with a Class I incisor relationship and bi-maxillary dento-alveolar protrusion on a Class I skeletal base. The occlusion was complicated by an ankylosed and moderately infra-positioned upper left permanent central incisor, an anterior crossbite, crowding, a reduced overbite and centreline discrepancy. The incisor was traumatised and avulsed when the root was immature and the tooth was reimplanted with delay. On referral for orthodontic treatment at age 11 .5 years, the upper left central incisor was experiencing ankylosis-related (osseous replacement) resorption and external root resorption simultaneously. Aside from the orthodontic aims, it was important to address the disrupted alveolar development to facilitate later prosthodontic replacement of the upper left permanent central incisor by idealising the inter-coronal and inter-radicular spaces. Treatment consisted of fixed orthodontic appliances in conjunction with the extraction of all second premolars and the upper left permanent central incisor with episodic surgical curettage. An upper Hawlix retainer was provided immediately at debond and a cantilevered resin-retained bridge was placed four months later.

Abstract
Esthetic rehabilitation of discolored anterior teeth is always a great challenge, especially in the presence of pathology. Fortunately, conservative management in the esthetic zone has become more feasible in compromised cases because of the development of restorative materials and advances in dental adhesives. This report presents a complicated case of a patient with tetracycline-related discoloration, multiple root resorption, and a periapical lesion. Treatment was conservative and used a natural tooth pontic and splinted porcelain laminate veneers.

Abstract
Internal root resorption is a consequence of chronic pulp inflammation. Later on, the pulp necrosis followed by a chronic apical periodontitis is installed. Hence, usually, in clinical practice, both lesions have to be simultaneously managed. Conventional periapical radiograph is mandatory in diagnosis. Improving the diagnosis and management of both lesions, cone beam computed tomography proves to be more reliable than conventional radiography.

Orthodontic treatment in cherubism: an overview and a case report. AUSTRALIAN ORTHODONTIC JOURNAL 2014; 30:214-220. [PMID: 25549525] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/04/2023]
Abstract
INTRODUCTION Cherubism is a rare hereditary disease that frequently manifests as a painless enlargement of the mandible and/or maxilla. The disease usually progresses rapidly during the first and second decades of life but it is self-limiting and often regresses. Although few orthodontic case reports describing cherubic patients exist, the timing and extent of surgical intervention is controversial. AIM This present paper aims to review the treatment literature and provide a case report of a patient who underwent orthodontic/surgical management. METHODS The patient presented with severe cherubism in her late teenage years; her main complaint was poor facial and dental appearance. Multiple teeth were missing and those present demonstrated significant preoperative root resorption. Treatment consisted of orthodontic alignment of the upper anterior teeth and a recontouring osteotomy. RESULTS Confirmed by the patient, the combination approach led to a significant improvement in facial aesthetics and better self-esteem. Tooth movement through the osseous lesions was uneventful and no further root resoption was observed. CONCLUSION Orthodontic treatment may be undertaken in those affected by Cherubism even with pre-existing idiopathic root resorption, but patients need to be appropriately informed and consented.

Abstract
INTRODUCTION To obtain essential information in clinical endodontics, cone-beam computed tomographic (CBCT) imaging can be used in all phases of treatment including diagnosis, treatment planning, during the treatment phase, and through post-treatment assessment and follow-up. The purpose of this article was to review the use of CBCT imaging in the diagnosis, treatment planning, and assessing the outcome of endodontic complications. METHODS Literature was selected through a search of PubMed electronic databases for the following keywords: tooth root injuries, tooth root radiography, tooth root perforation, tomography, cone-beam computed tomography, endodontic complications, tooth root internal/external resorption, root fractures, and broken instruments. The research was restricted to articles published in English. One hundred twelve articles met the inclusion criteria and were included in this review. RESULTS Currently, intraoral radiography is the imaging technique of choice for the management of endodontic disease, but CBCT imaging appears to have a superior validity and reliability in the management of endodontic diagnosis and complications. CONCLUSIONS Endodontic cases should be judged individually, and CBCT imaging should be considered in situations in which information from conventional imaging systems may not yield an adequate amount of information to allow the appropriate management of endodontic problems. CBCT imaging has the potential to become the first choice for endodontic treatment planning and outcome assessment, especially when new scanners with lower radiation doses will be available.

Abstract
The purpose of this case report is to discuss the four-year follow-up of a transalveolar transplantation of an impacted immature permanent mandibular left canine. A nine year-old-boy was referred to the dental school because of a mandibular swelling associated with the impacted canine. Under local anesthesia, the tooth was extracted and transplanted in its own space, followed by a two-week orthodontic fixation. The radiographic examination two months later revealed the presence of external inflammatory root resorption, which was treated with an apexification. The overall status of the transplanted tooth and the surrounding hard and soft tissues four years post-treatment indicates a successful outcome.

Abstract
External root resorption (ERR) is an uncommon and intractable disease. Treatment alternatives are case-dependant and aim for the repair of the resorptive lesion and long-term retention of the tooth. A forty-year-old Asian female was diagnosed with idiopathic ERR on tooth #11 (the left maxillary canine) by CBCT. Non-surgical root canal therapy was completed with the aid of an operating microscope. The apical third of the root canal was filled with warm gutta-percha and the resorption defect was filled with mineral trioxide aggregate (MTA). The periapical radiographs were taken immediately after operation, one-month follow-up, six-month follow-up and three-year follow-up, respectively. Clinically, the canine was asymptomatic, and no evidence of any further resorption was found. The six-month follow-up radiograph showed initial healing of the bony lesion, while the three-year follow-up radiograph manifested almost complete healing. MTA can be a superior material to be successfully used in the non-surgical treatment of ERR. CBCT is very useful for evaluating the true nature and severity of absorption lesions in root resorption. It is the first complete case report from China about non-surgical treatment of severe ERR along with a relatively long term follow-up.
