Saudi Dent J 2021; 33:1012-1017. [PMID: 34938044 PMCID: PMC8665173 DOI: 10.1016/j.sdentj.2021.06.005] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Revised: 06/03/2021] [Accepted: 06/14/2021] [Indexed: 11/30/2022] Open
Abstract
Aim The aim of this is to evaluate the prevalence and location of the accessory mental foramen (AMF) in a Saudi population using cone-beam computed tomography (CBCT). Methodology CBCT data were retrieved from two dental facilities at two universities located in two different cities and filtered over a period of four years. The scans were aligned when the AMF was noticed, and then the size of both the AMF and mental foramen (MF), its location, and the distance from the AMF to the MF were recorded. The AMF measurements were compared between males and females and between the two sides of the mandible. Results In total, 603 CBCT scans were investigated. The percentage of scans with an AMF was 9.95% (n = 60), and AMFs were almost equally distributed on both sides. Only four cases (0.66%) of a second AMF were detected among the scans. The MFs on both sides were significantly larger in males than in females (P > 0.05), but they showed no differences in the sizes of the AMFs. The AMFs were most commonly located inferior and posterior to the MF. The distance between the MF and AMF ranged from 2.32 to 5 mm. Conclusions The prevalence of the AMF in this Saudi population was 9.95%, and it was significantly more prevalent in males than in females. Its proximity to the MF makes it clinically important to conduct proper detailed planning prior to performing any procedure that might risk the vital structures.

Mental Nerve Paraesthesia: A Report of Two Cases Associated with Endodontic Etiology. Case Rep Dent 2021; 2021:1747519. [PMID: 34691788 PMCID: PMC8528636 DOI: 10.1155/2021/1747519] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2021] [Accepted: 09/30/2021] [Indexed: 11/25/2022] Open
Abstract
Paraesthesia of the mental nerve can occur due to various etiological factors. Rarely, dental infections can cause paraesthesia. However, this article discusses two cases of endodontic etiology in the mental nerve region as a causative factor for paraesthesia. In the first case, the patient had severe pain localized to his right mandible, with numbness of his lower lip. Endodontic treatment led to quick regression and resolution of paraesthesia. In the second case, a patient who was referred for retreatment of a mandibular second premolar infection developed profound paraesthesia in the region of the mental nerve distribution following prior therapy. Possible mechanisms responsible for periapical infection-related paraesthesia are discussed here. CBCT imaging may be useful in the diagnosis and management of such conditions.

Abstract
BACKGROUND Paresthesia is defined as a burning or prickling sensation or partial numbness caused by neural injury. OBJECTIVE The purpose of this paper is to present a rare and unusual case report of odontogenic infection-induced inferior alveolar nerve (IAN) paresthesia along with cutaneous draining sinus on the face of a pediatric patient and to discuss the possible pathophysiologic mechanism of nerve injury. METHODS A 14-year-old female patient with cutaneous sinus and paresthesia associated with inferior alveolar nerve was enrolled in the study and the clinical and radiological manifestations of sinus lesion were carefully evaluated. RESULTS The most appropriate treatment was carried out not only to resolve extraoral sinus but also to ensure progressive healing for the complete resolution of neurological disturbance. CONCLUSION The simultaneous occurrence of infection and paresthesia strongly suggested a definitive relationship. Therefore, there seems to be a correlation between duration, origin, significance of the injury and the prognosis of paresthesia.

Abstract
Various dental procedures, such as injection administration, surgical treatment, and endodontic treatment, can cause injury to the nerves. The most commonly injured nerves are the inferior alveolar and lingual nerves. This can manifest as altered sensation to the area of innervation of the injured nerve, such as the lower lip, chin, teeth, tongue, and mucosa. Altered sensations or loss of sensation are relatively infrequent complications in daily dental practice. Here, we report an uncommon case of altered sensation in the midfacial region caused by an endodontic procedure and discuss the need to consider local dental causes in the differential diagnosis of numbness in the facial region.

Abstract
Aims Periapical lesions have been implicated in mandibular trigeminal sensory neuropathy. This study aimed to report on a case series of consecutive patients presenting with mandibular division trigeminal nerve injuries (TNI) caused by periapical lesions. Common presenting characteristics and possible strategies for management were also investigated.Materials and methods A retrospective study of 22 patients with TNI caused by periapical lesions. Data were extracted from patient records and analysed using Microsoft Excel and SPSS. Factors associated with TNI resolution were assessed using Student's t-Tests and one-way Analysis of Variance (ANOVA), where P <0.05 indicated statistical significance.Results Twenty-one patients had inferior alveolar nerve injuries (IANI) and one had a lingual nerve injury (LNI). The most commonly affected teeth were the first molars (11 patients; 50%). TNI symptoms included numbness, pain and/or paraesthesia. IANI resolved completely among five patients within a mean time of 4.7 months (range 1.5-12 months). Patients who showed complete resolution had the affected teeth extracted or primary endodontic treatment with antibiotics.Conclusions Patients with TNI caused by periapical lesions can suffer significantly from combined numbness, pain and paraesthesia. Resolution of these injuries may be maximised upon early diagnosis and treatment of the periapical lesion by tooth extraction or primary endodontic treatment.

Infection Related Inferior Alveolar Nerve Paresthesia in the Lower Premolar Teeth. Case Rep Dent 2016; 2016:2623507. [PMID: 27597904 PMCID: PMC4997022 DOI: 10.1155/2016/2623507] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2016] [Revised: 07/24/2016] [Accepted: 07/25/2016] [Indexed: 12/02/2022] Open
Abstract
Introduction. The aim of this paper was to describe two cases of IAN infection-induced paresthesia and to discuss the most appropriate treatment solutions. Methods. For two patients, periapical lesions that induced IAN paresthesia were revealed. In the first case, the tooth was previously endodontically treated, whereas in the second case the lesion was due to pulp necrosis. Results. For the first patient, a progressive healing was observed only after the tooth extraction. In the second patient, the paresthesia had resolved after endodontic treatment. Conclusions. The endodontic-related paresthesia is a rare complication that can be the result of a combination of etiopathogenic mechanisms such as mechanical pressure on the nerve fibers due to the expanding infectious process and the production of microbial toxins. Paresthesia resulting from periapical lesions usually subsides through elimination of infection by root canal treatment. However, if there are no signs of enhancement, the immediate extraction of the tooth is the treatment of choice in order to prevent irreversible paresthesia because it was demonstrated that there is a correlation between the duration of mechanical or chemical irritation and the risk of permanent paresthesia.

Abstract
Many systemic and local factors can cause paresthesia, and it is rarely caused by infections of dental origin. This report presents a case of mental nerve paresthesia caused by endodontic infection of a mandibular left second premolar. Resolution of the paresthesia began two weeks after conventional root canal treatment associated with antibiotic therapy and was completed in eight weeks. One year follow-up radiograph indicated complete healing of the radiolucent periapical lesion. The tooth was asymptomatic and functional.

Abstract
Neuropathic pain is caused by neural injury or painful states associated with either peripheral or central nerve injury. One of the aetiologies of this type of pain is iatrogenic trauma. This case highlights the features of peripheral neuropathic pain caused by foreign body left in the mental foramen following a previous surgical procedure. The foreign body was detected on routine radiographic evaluation. Once the foreign body was removed by surgical intervention, the pain resolved. This stresses the importance of routine radiographic evaluation in proper diagnosis and treatment planning in the management of neuropathic pain. This paper also sheds light on the role of iatrogenic mechanical cause of peripheral neuropathic pain and warrants a tough degree of caution on the part of oral clinicians.

Abstract
Frequently reported is a case wherein a lesion caused by periodontitis or periapical lesion in a natural tooth enlarged, invaded the inferior alveolar nerve canal, and induced paresthesia. Cases wherein paresthesia occurred because of peri-implantitis have been rarely reported. The patient in this case report had experienced transient paresthesia after implant placement and recovered normal sensation 3 months later. Thirteen years later, this patient visited the authors' hospital with paresthesia in the same region because the peri-implantitis progressed to the apex of the implant. One week after removal of the implant, sense recovery and pain relief started, and 15 days after removal, the paresthesia and pain completely disappeared. For patients who experience transient paresthesia and recovery owing to nerve damage caused by the placement of an implant in the mandibular molar or premolar area, or in patients in whom the implant is close to the inferior alveolar nerve canal or the mental nerve, the spread of inflammation caused by peri-implantitis can induce paresthesia.

Abstract
The purpose of this systematic review was (a) to search for clinical articles pertaining to success and failure of nonsurgical root canal therapy, and (b) to assign levels of evidence to these studies. Electronic and manual searches were conducted to identify studies published between January 1966 and September 2004 with information on the success and failure of nonsurgical root canal therapy. Articles were reviewed and graded for strength of level of evidence (LOE) from one (highest level) to five (lowest level). This review resulted in the identification of 306 clinical studies related to this topic area. Six articles were randomized controlled trials (RCTs, LOE 1). This search also identified 12 low-quality RCTs (LOE 2), 14 cohort studies (LOE 2), five case-control and eight cross sectional studies (LOE 3), four low-quality cohort studies (LOE 4), and five low-quality case-control studies (LOE 4). The majority (73) of the often-quoted "success and failure" studies were case series (LOE 4). The rest of the articles were descriptive epidemiological studies (42), case reports (114), expert opinions (18), literature reviews (4), and one meta-analysis. Based on these findings, it appears that a few high-level studies have been published in the past four decades related to the success and failure of nonsurgical root canal therapy. The data generated by this search can be used in future studies to specifically answer questions and test hypotheses relevant to the outcome of nonsurgical root canal treatment.

Abstract
The objective of this retrospective study was to determine how often paresthesia occurs and to examine the role of the anatomy of the inferior alveolar nerve (IAN). The study took the form of a review of the records of the endodontic department at the Creighton University School of Dentistry, a literature review, and cadaver dissections. The result showed that of 6313 teeth treated during a 7-yr period, 832 were mandibular premolar teeth. The eight reported cases of paresthesia in that group reflected an incidence of 0.96%. Observations of dissected human-cadaver mandibles indicated that the paresthesias of the mandible could be related to the confinement of the IAN within the limits of the mandible. It was concluded that these paresthesias were related to the intrabony course of the IAN through the mandible, which contributed to the paresthesia symptoms.

Abstract
We experienced two cases of inferior alveolar nerve paresthesia caused by root canal medicaments, which were successfully relieved by microscopic endodontic treatment. In the first case, the paresthesia might have been attributable to infiltration of calcium hydroxide into the mandibular canal through the root canals of the mandibular left second molar tooth. In the second case, the paresthesia might have been attributable to infiltration of paraformaldehyde through the root canals of the mandibular right second molar tooth. The paresthesia was relieved in both cases by repetitive microscopic endodontic irrigation using physiological saline solution in combination with oral vitamin B12 and adenosine triphosphate.
