An impacted left mandibular second molar (tooth 37) was extracted, but most of its dental follicle remained in the socket. The crown and dental papilla of an unerupted, left mandibular third molar (tooth 38) were then placed into the socket of tooth 37. Successful interaction between the dental follicle of tooth 37 and the crown and dental papilla of tooth 38 led to the formation of a new tooth...

Tooth impaction is defined as any tooth that fails to erupt into a normal functional position and remains unerupted beyond the time at which it should normally erupt. Reports of impaction and eruption failure in primary teeth are relatively rare compared to permanent teeth. We report 2 rare cases where the second premolar was located on the occlusal side of the impacted mandibular second primar...

primary tooth impaction is a rare finding during the development of primary dentition. several factors contribute to the impaction of a deciduous tooth. this report describes the diagnosis and treatment of a 10-year-old boy who presented an impacted second primary mandibular molar. this tooth, located inferior to the second premolar together with an odontoma, was positioned superior to the prem...

Tooth transplantation can be considered a valid and predictable treatment option for rehabilitating young patients with permanent teeth loss. This study presents several cases of successful autogenous tooth transplantation with a 6-9 months follow-up. Tooth auto-transplantation can be considered a reasonable option for replacing missing teeth when a donor tooth is available. The auto-transplant...

This paper describes the autologous transplantation of a mandibular right third molar to replace the residual roots of the second molar in the same quadrant, preserving function and aesthetics. A 5-year clinical and radiographic follow-up was undertaken. After transplantation, the donor tooth received endodontic treatment and placement of calcium hydroxide, which was periodically replaced every...

Supernumerary teeth are among the most common dental anomalies affecting the primary and permanent dentition. They are usually found in the anterior maxilla and occur infrequently in the primary dentition. The purpose of this paper was to report a case diagnosed with primary supernumerary tooth in the primary second molar region. The crown and root shape of the primary supernumerary tooth resem...

background and aims. hypodontia is a common developmental abnormality of dentition. this study aimed to determine tooth width in patients affected with mild hypodontia and compare the results with a control group without tooth agenesis. materials and methods. the orthodontic records of 25 patients with congenital missing of one or two teeth (hypodontia group), and 25 subjects with full dentitio...

abstract : a 28-year old patient was referred for endodontic treatment of his left mandibular second molar. the patient had no history of systemic diseases and his chief complaint was spontaneous pain in left posterior region of mandible. clinically, there was a deep caries in the left mandibular second molar. radiographic examination of this tooth revealed a long crown containing large pulp ch...

missing of mandibular second premolar is one of the most common types of tooth agenesis. in such cases, maintenance of the primary second molar, if possible at all, can prevent many treatment procedures in future. the present case report represents the endodontic management of a necrotic left mandibular primary second molar that had developed an abscess. considering the missing of the permanent...

Ankylosis of primary mandibular molars has been routinely found to be associated with various developmental disturbances in permanent dentition such as aplasia of the succedaneous tooth, ectopic eruption of the premolar, infraoclusion of the ankylosed tooth leading to tipping of the first permanent molar etc. This article describes a rare case where there was ankylosis of a mandibular second pr...
