background and aims. the knowledge of variations in root canal morphology is critical for a successful endodontic treatment. the purpose of this study was to investigate variations in the root canal system of human mandibular first permanent molars in an iranian population. materials and methods. in this study, 209 mandibular first molar teeth were decalcified, dye-injected, and cleared in orde...

we report the delayed eruption and infraocclusion of a mandibular second primary molar with ectopic location of the permanent successor. this was a rare case where the second premolar was located to the distal side of the impacted mandibular second primary molar. early intervention is recommended to manage orofacial disfigurement and prevent consequent problems.

AIM To study the treatment management of first permanent molars in children with Molar-Incisor Hypomineralisation (MIH). STUDY DESIGN Retrospective analysis. METHODS The records of the clientele of a private paediatric dental practice were scanned. Thirty-six cases of children fulfilling the diagnostic criteria of MIH were retrieved who had been followed for a mean period of 4.5 years, and ...

_The world of endodontics has incorporated new technologies, instruments and materials in the past decade, such as operating microscopes, digital radiography, CBCT, NiTi rotary shaping files, sonic and ultrasonic instruments, and new irrigation delivery systems. However, despite all these improvements, the overall outcome, especially of non-surgical endo dontics, has not increased significantly...

OBJECTIVE The aim of the study was to analyze the prevalence and distribution of ectopic eruption of the permanent maxillary first molar (EEM) in individuals scheduled for orthodontic treatment and to investigate the association of EEM with dental characteristics, maxillary skeletal features, crowding, and other dental anomalies. METHODS A total of 1,317 individuals were included and randomly...

INTRODUCTION The main goal of endodontic therapy is to prevent or heal apical periodontitis. However, root canal anatomy might present a clinical challenge directly related to the treatment outcome. The purpose of this study was to review published literature related to root anatomy and root canal configuration of the permanent mandibular first molar. METHODS An exhaustive search was undertak...

Mesial rotation of maxillary first molar around palatal root is a most commen cause of class II molar relationship in class II subjects. Assessment of molar rotation is important because it utilizes 2-3mm of space in anteroposterior plane. There are different methods for assessment of its rotation which is very important in diagnosis and treatment planning of class II malocclusion. Cephalometri...
