Thus, the aim of the present study was to examine the relationship of JAR to IAN, cortical plates, and its position with regards to IAN and tooth angulation. \u0000Materials and Methods: The present case-control study comprising a sample of 545 Cone Beamed CT scans of mandibular third molars examined 75 JAR cases and 75 control teeth. The relationship of JAR to IAN, its position with regards to IAN, lingual cortical plate thinning, teeth position and angulation were investigated. Descriptive analyses, chi-square and fisher exact tests were performed with a value of 0.05 considered significant. \u0000Results: Mesioangular teeth were the most common in both groups. Based on tooth angulation, no significant difference was detected between case and control groups (p value = 0.346). There was no significant difference between the two groups, with regards to JAR and tooth proximity to IAN (p value = 0.578). Although, the most prevalent position in the JAR group was lingual and superior in the control group, but no significant difference was observed between them (p value = 0.122). Most cases of JAR (84.0%) and most cases of control group (77.3%) showed some degree of cortical thinning. Based on this, no significant difference was present between the JAR and control groups (p value = 0.626). \u0000Conclusion: JAR is generally in contact with mandibular canal and some degree of cortical thinning manifest in most of these cases. These findings suggest a possible increase in the risk of nerve injury during surgical removal of third molars.","PeriodicalId":221865,"journal":{"name":"Journal of Isfahan Dental School","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116269859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anomaly in tooth size and shape is due to disturbances in a sequence of morph differentiation and his to differentiation in tooth bud formation periods and is more common in permanent dentition than deciduous teeth. The most common tooth size discrepancy is in the upper lateral incisor and upper and lowers 2nd premolar teeth. About 5% of malocclusions are due to tooth size discrepancy. For having the best occlusion, we must have the appropriate size and shape of teeth. As there is a relation between deciduous and permanent teeth, proper evaluation and timely intervention are essential for achieving a good occlusion in anterior and posterior segments of permanent teeth. Thus we need interceptive orthodontic in mixed dentition period with a good treatment plan for removing the malformed tooth at the proper time and appliance therapy for eruption guidance of other teeth. \u0000Case Report: A rare tooth anomaly (double teeth) in deciduous teeth: The case reported here is a 9- years old boy with a delayed eruption of the right lower permanent lateral incisor and gemination of lower right deciduous canine and crowded upper incisors that refer to the orthodontic department of dental school of Ahvaz Jundishapur University of Medical Sciences on7th October of 2020. \u0000Conclusion: After creating patient’s file, the further steps of molding from the patient and gathering all diagnostic records such as panoramic radiography, intraoral photography was carried out and ordered to remove the malformed baby tooth afterward.
