[PMID: 38699897 DOI: 10.1111/aej.12853] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Revised: 03/12/2024] [Accepted: 04/24/2024] [Indexed: 05/05/2024]
Abstract
Pre-eruptive intracoronal resorption is a rare dental anomaly marked by a radiolucent area within an unerupted tooth. This report discusses the clinical management of pre-eruptive intracoronal resorption in two mandibular premolars through vital pulp therapy using Biodentine as a sealant. Emphasising the significance of timely intervention for preserving pulp vitality and the tooth's integrity, the present case report underscores the necessity of vigilant clinical and radiographic monitoring for early detection and appropriate treatment. By presenting effective strategies for managing pre-eruptive intracoronal resorption, the report contributes to the understanding of this condition and highlights the importance of proactive measures in preserving affected teeth and ensuring favourable long-term outcomes.

Abstract
This retrospective study aimed to investigate the prevalence of pre-eruptive intracoronal resorption (PEIR) using cone-beam computed tomography (CBCT) and to explore the mechanism and characteristics of PEIR development. CBCT images of patients aged ≤ 20 years with unerupted teeth at Hiroshima University Hospital were collected. We examined 1530 patients with 10,576 unerupted teeth. Teeth with PEIR were identified for the detailed location and size of the PEIR in the crown using multiplanar reconstruction. The subject and tooth prevalence rates of PEIR were 1.96% and 0.31%, respectively. The teeth that were the most commonly affected by PEIR were mandibular third molars (3.09%). The prevalence of PEIR was significantly higher in females than in males, and higher in the mandible than in the maxilla. No significant difference between in the position of PEIR within the crown was observed. Moreover, CBCT imaging revealed the onset of PEIR in one case. This study demonstrated the prevalence of PEIR and identified statistically significant sex- and location-based differences. Furthermore, one case of CBCT imaging supports the hypothesis that the onset of PEIR was due to resorption after completion of the crown.

Heliyon 2023; 9:e18699. [PMID: 37560674 PMCID: PMC10407135 DOI: 10.1016/j.heliyon.2023.e18699] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Revised: 07/18/2023] [Accepted: 07/25/2023] [Indexed: 08/11/2023] Open
Abstract
OBJECTIVES The aim of this retrospective study was to analyze the occurrence and characteristics of pre-eruptive intracoronal resorptions in a clinical orthodontic patient population. MATERIALS AND METHODS Patients treated in an orthodontic department (University of Pécs, Pécs, Hungary) were included. Unerupted teeth on panoramic radiographs were analyzed for intracoronal radiolucent lesions. For each patient, the demographic data, jaw localization, number of unerupted teeth with pre-eruptive intracoronal resorption lesions, number of lesions per tooth, size and localization of pre-eruptive intracoronal resorption defects, affected tooth's surface, pulp involvement and ectopic position of the tooth with defects were recorded. RESULTS In the 3,143 patients investigated, 55 teeth in 49 patients showed pre-eruptive intracoronal resorption lesions (subject incidence: 1.56%). The incidence on unerupted teeth was 0.25%. Pre-eruptive intracoronal resorption was significantly more common in mandibles (43 mandibular vs. 12 maxillary lesions) with an odds ratio of 12.84 (95% Confidence Interval: 5.19-31.74) and no gender differences were found (p = 0.746). The occurrence of pre-eruptive intracoronal resorption was highest in the youngest (7-10 years) mixed dentition status group (p < 0.001). Most of the lesions (44 of 55, or 80.0%) were localized in the dentin, occupying two-third or less of the dentin thickness. Only 12.73% (7/55) of the lesions were not localized on the occlusal surface. Of the lesions, 89.1% (49/55) showed no obvious size increase over an average follow-up of 36.4 ± 8.1 months. CONCLUSIONS Pre-eruptive intracoronal resorption may occur mainly in the mixed dentition stage in orthodontic patients. Careful and attentive radiographic evaluations may facilitate early detection and follow-up of the lesions' possible dimensional changes, especially when resorption influences orthodontic extraction therapy.

Abstract
Reports on the histopathologic features of external cervical resorption (ECR) in unerupted teeth are scarce. This article reports on 2 maxillary impacted canines from different patients that showed ECR lesions and were surgically removed and histologically evaluated. Case 1 showed symptoms associated with oral communication of the dental follicle and pulpal exposure. Radiographs and cone-beam computed tomographic imaging showed that resorption affected a large part of the root and the crown. Case 2 was asymptomatic, and the resorption cavity was restricted to the tooth crown. Both teeth were extracted and subjected to histologic processing and analysis. In case number 1, the coronal pulp was necrotic and infected, showing areas of exposure to the resorption channels. The apical pulp was vital and uninflamed. The pulp space was surrounded by a continuous pericanalar resorption-resistant sheet. Part of the resorbed area of dentin was occupied by inflamed granulation tissue. More apically, a network of trabecular bone was present in the resorbed area. In case number 2, the pulp around the resorbed area was uninflamed and vital. A large fraction of the lost dentin was replaced by trabecular bone, closely adapted to the irregularly resorbed dentin surface, and no inflammatory cells. Our findings indicate that impacted teeth with ECR may remain asymptomatic until associated with infection. Histologic features of resorption in impacted teeth were similar to those in erupted teeth. In the case associated with infection, the resorbed area was occupied by inflamed tissue and newly formed bone. In the case with no infection, the resorption area was filled with bone undergoing a remodeling process.

Abstract
Pre-eruptive intracoronal resorption (PEIR) is usually an incidental finding as a radiolucent lesion within the coronal dentin of unerupted teeth. Through the four cases reported here, authors would demonstrate deeply impacted "high-risk" third molars with PEIR defects, showing an increased risk of inferior alveolar nerve (IAN) injury. However, follow-up or coronectomy may eliminate or reduce the risk of neurosensory disturbances, in case of PEIR lesions this can be contradictory due to the unpredictable reactions of the third molar's pulp. Cases show the important role of preoperative imaging in the diagnostics and management of deeply impacted PEIR third molars and highlight the need for investigations regarding coronectomy in such cases.

Abstract
BACKGROUND Pre-eruptive intracoronal radiolucency (PEIR) poses a challenge to paediatric dentists as it cannot be clinically detected. AIM To estimate the prevalence and coexisting factors of PEIR in permanent teeth of children and adolescents in western Tamil Nadu, India. DESIGN This cross-sectional study assessed 5012 digital panoramic radiographs of children and adolescents below 14 years of age obtained from private digital imaging centers, dental clinics, and dental colleges located in five districts of western Tamil Nadu. The prevalence and PEIR and its coexisting factors were assessed by two independent calibrated investigators. Data were analyzed using the chi-square test. RESULTS The subject prevalence and tooth prevalence of PEIR were estimated to be 3.2% and 0.4%, respectively. Maxillary canines and mandibular premolars were commonly involved. Majority of the lesions were limited to less than one-third of dentin thickness (74%) and distal aspect of the crown (45.1%). Ectopic positioning (9.3%) and dental caries in the preceding primary tooth (9.9%) were the most common coexisting factors. CONCLUSION Pre-Eruptive Intracoronal Radiolucency defects were commonly seen in maxillary canines, mandibular premolars, and distal aspect of the crown involving less than one-third dentin thickness. Ectopic positioning and caries in primary teeth were commonly seen along with the PEIR defects.

Abstract
Purpose The purpose of this study was to evaluate the relationship between idiopathic coronal resorption and age in adult patients. Materials and methods 3405 digital panoramic radiographs present in the archive of the radiology department belonging to 1584 males and 1821 females aged 25 and over were assessed by two oral and maxillofacial radiologists. The patients' age, gender, number of impacted teeth, number and position of teeth with idiopathic coronal resorption and the extent of coronal resorption were recorded on standard forms. Results A thousand and nine impacted teeth were observed in 622 patients (304 males and 318 females) with a mean age of 36,92 (±10,85). Idiopathic coronal resorption was present in 26 of the 622 patients with a frequency of 4.2%. One patient had two teeth with idiopathic coronal resorption; resulting in as 27 teeth and a frequency of 2.7% according to tooth number. There were 13 (50%) females and 13 (50%) males having idiopathic coronal resorption. There was no significant difference between genders. The presence of idiopathic coronal resorption increased with advanced age (v: 0,193, p<0.05). There was no statistically significant difference between the extent of the coronal resorption and age. Conclusion The presence of idiopathic coronal resorption increases with advancing age. Idiopathic coronal resorption is detected incidentally during radiographic examination. Thus, dentists should consider this situation and should perform periodically radiographic examination of impacted teeth.

Abstract
Aim and objective The present article aims to describe and discuss the preventive clinical management of a pre-eruptive intracoronal resorption (PEIR) defect on a maxillary right second premolar of an 11-year, 5-month-old girl. Background Pre-eruptive intracoronal resorption is described as an abnormal, well-circumscribed, radiolucent area, occurring within the coronal dentinal tissue close to the dentinoenamel junction of unerupted teeth and extending into various depths of the dentin. It is a rare anomaly occurring in primary and permanent dentitions. In the past, these defects were misdiagnosed as caries, and were therefore called “pre-eruptive caries” or “hidden caries”. Currently, the most acceptable etiological hypothesis for PEIR is intracoronal resorption by the invasion of resorptive cells into the dentine through breakdowns in the enamel during crown formation. These lesions are often detected accidentally during routine dental radiographic examination. Case description A fissure sealant was applied to the affected tooth shortly after its eruption. Clinical and radiographical assessments were scheduled every 6 months for a period of 5 years and 5 months. Conclusion The preventive approach proved to be effective in preserving the tooth vital and asymptomatic with normal root development for the entire follow-up period. Clinical significance This article raises awareness about misdiagnosed PEIR in primary and permanent dentitions. A close inspection of radiographs, taken during routine visits and orthodontic check-ups, is important for early detection and proper management of such defects.

Abstract
AIM To discuss prevalence, characteristics, aetiology and pathophysiology, diagnosis and management of pre-eruptive intra-coronal radiolucency/resorption (PEIR) defects, and to highlight the clinical significance of PEIR. METHODS A literature research from Pubmed Medline database was adopted to identify the relevant published articles related to PEIR using keyword search strategy; other papers were obtained through searching the reference lists. Significant findings were summarised and presented in this review. RESULTS Subject prevalence was (0.2-27.3%) and tooth prevalence was (0.2-3.5%); depending on factors such as type of radiograph used for assessment, demographic factors, age range included, and dentition stage. Currently, the most acceptable etiologic theory for PEIR is intra-coronal resorption by invasion of resorptive cells into forming dentine via an interruption of crown formation; most likely to be caused by local factors such as ectopic position of affected tooth or adjacent tooth next to it. Diagnosis of PEIR lesions occurs, as they are noted incidentally on routine dental radiographs of unerupted teeth. A management protocol for PEIR defects has been suggested based on the literature. The clinical significance of these lesions is that they could constitute a large proportion of occult caries, and can be associated with developmental defects, ectopic positioning and supernumerary teeth, and a delay in dental development. CONCLUSIONS Early diagnosis of PEIR defects by careful viewing of radiographs of unerupted teeth is important as part of clinical examinations to allow early treatment.

Abstract
Preeruptive intracoronal radiolucencies (PEIRs) are mostly incidentally found by routine radiographic examination of unerupted teeth. PEIRs are classified into two types according to the nature of the lesion: progressive and nonprogressive. A case report of a 17-year-old boy with a nonprogressive PEIR on the permanent mandibular left second molar is presented. The lesion was initially detected on an unerupted tooth at age eight years, eight months. It was clinically and radiographically assessed yearly. Cone beam computed tomography (CBCT) was used to evaluate the lesion's size and location when the patient was 11 and 14 years old. The assessments confirmed that the lesion was nonprogressive and had no connection to the pulp or oral cavity. Due to the static nature of the detected PEIR during the nine-year follow-up period, the patient's low caries-risk status, and high patient and parental cooperation in periodic dental care, it was decided to place resin sealant on the affected tooth and monitor the lesion without any operative treatment.

Abstract
AIM The aim of the present study was to determine the prevalence, location, size, and tooth type of pre-eruptive intracoronal radiolucencies (PEIR) from panoramic radiographs in Thai patients. METHODS A retrospective study of PEIR was conducted on 1599 panoramic radiographs of 629 Thai males and 970 Thai females with an age range of 4-20 years (average age: 14.0 ± 4.0 years). Each radiograph was reviewed by two calibrated examiners. The age and sex of the patients, location, size, and tooth type of the lesions were recorded. The SPSS program was used for statistical analysis. RESULTS The PEIR were found in 0.32% of tooth samples (29/9060) and 1.63% of patients (26/1599). There was no statistical difference in the presence of PEIR between both sexes. The mandibular second molars were the most affected teeth. The lesions were mostly located at the central part of the crown. The lesion sizes were mostly limited to less than one-third of dentinal thickness. CONCLUSIONS The present study showed that the prevalence of PEIR in Thai samples is 1.63%. This could raise dentists' awareness in reviewing unerupted teeth in panoramic radiographs. Early detection of the lesions should aid in proper treatment planning of affected teeth to prevent complications from carious invasion after tooth eruption.

Abstract
Radiolucent or hypodense lesions in the crown of unerupted teeth may be due to pre-eruptive intracoronal resorption. Clinicians must be aware of this risk so that they can diagnose and appropriately treat this condition. The purpose of this study is to present a well-documented clinical case of pre-eruptive intracoronal resorption in an impacted third upper left molar of a 63 year old female patient. This was an unexpected finding, which occurred after cone-beam computed tomography was used to investigate the first upper left molar, which had an acute periradicular abscess. A multidisciplinary team followed up the case to describe clinical, radiographic and histological findings. The available treatment options were discussed, and the tooth extraction was the option chosen. Previous case studies describing such resorption in third upper molars have not been reported. This case shows that all permanent teeth in a pre-eruptive stage must be analysed radiographically to detect early pre-eruptive intracoronal resorption.

Abstract
OBJECTIVE This study aimed to investigate the prevalence of pre-eruptive intracoronal resorption (PIR) using cone beam computed tomography (CBCT) and panoramic radiography and to compare the findings of these imaging techniques. METHODS This retrospective study consisted of 733 patients who had at least one unerupted tooth and had undergoneimaging with both three-dimensional (3D) CBCT and two-dimensional (2D) panoramic radiography. In all the images, the number of teeth with intracoronal resorption, affected tooth type and number, and size and location of the PIR defects were recorded. The McNemar test was used to compare the prevalence of PIR in the CBCT and panoramic images. RESULTS Fewer PIR defects were detected in the panoramic images (3.1% of the patients) than in the CBCT images (9.5% of the patients) (p< .001). According to the CBCT images, the distribution of PIR defects was as follows: third molars (59.5%), canine teeth (11.4%), second molars and premolars (7.6% for both), supernumerary teeth (5.1%), second molars (3.8%), central incisors (2.5%), and first premolar and primary second molar teeth (1.5% for both). According to the scoring classification system for PIR defects, PIR 1 defects were the most common (65.8%), followed by PIR 3 (24.1%) and PIR 2 (10.1%). Of these defects, 69.6% were located in the central aspect of the crown. Ectopically positioned teeth showing intracoronal resorption accounted for 51.9% of the cases of PIR. CONCLUSIONS CBCT detected more cases of PIR than panoramic radiography. The mandibular third permanent molar was the most commonly affected tooth.

Abstract
OBJECTIVES This retrospective study aimed to investigate the prevalence of pre-eruptive intracoronal resorption (PIR) in unerupted permanent teeth in a Turkish population using cone beam computed tomography (CBCT). METHOD A total of 1,317 CBCT images were screened. In all the images, the following were recorded: the number of unerupted teeth, number of teeth with intracoronal resorption, affected tooth type and number, and location of radiolucent defects. Demographic data were also obtained. RESULTS The prevalence of intracoronal resorption in the study group was 15.1%, with a prevalence in teeth of 3.5%. The prevalence of intracoronal resorption using CBCT was much higher than that recorded previously using panoramic or bitewing radiographs intracoronal resorption was more common in males (57%) than females (43%). Twenty-three cases were located in the maxilla (48%), and 25 were located in the mandible (52%). The mandibular third molar was the most affected tooth type, followed by maxillary third molars and supernumerary teeth. CONCLUSION CBCT can be useful for diagnosing PIR defects because it provides an accurate representation of internal dental anatomy. SCANNING 38:442-447, 2016. © 2016 Wiley Periodicals, Inc.

Abstract
There are six distinct types of resorption of dental hard tissue that occur in association with unerupted and impacted permanent teeth. These pathologic entities differ markedly from one another in terms of their aetiology, their treatment and their prognosis. In several of them, the continued existence of the affected tooth may be in danger while in others, conservative treatment may halt the resorption process and provide for a successful outcome. The treatment approach is specific for each type and is entirely dependant on the diagnosis. This presentation will discuss prevalence, aetiology, presenting symptoms and clinical signs, radiographic features, histopathology, differential diagnosis, treatment and prognosis in relation to each of the conditions.
