Comparison of transverse maxillary dental arch width changes with self-ligating and conventional brackets in patients requiring premolar extraction - A randomised clinical trial.

Objective: The purpose of this study was to evaluate, the change in the transverse maxillary arch dimensions, in patients requiring all first premolar extractions when using Active and Passive Self-ligating brackets, and comparing them with Conventional brackets.

Materials And Methods: This study was a non-blinded randomised clinical trial, which consisted of 42 patients (21 males and 21 females) within the age group of 16-25 years, having bimaxillary protrusion. They were divided into three groups with 14 patients each.

Management of unilaterally impacted multiple posterior teeth: a case report.

Introduction: The impaction of permanent teeth poses a challenge to orthodontists, especially when posterior teeth are involved. Multiple impacted posterior teeth without associated with systemic conditions/syndromes is an uncommon clinical occurrence which leads to a posterior open bite and severely compromised function.

Aim: The present article reports the clinical management of an impacted maxillary second premolar, mandibular premolars and mandibular first and second molars on the right side.

Prevalence of tooth size discrepancy among North Indian orthodontic patients.

Objective: To determine the prevalence of tooth size discrepancy (TSD) in a representative orthodontics population, to explore how many millimeters of TSD is clinically significant and to determine the ability of simple visual inspection to detect such a discrepancy.

Materials And Methods: The sample comprised 150 pretreatment study casts with fully erupted and complete permanent dentitions from first molar to first molar, which were selected randomly from records of the orthodontic patients. The mesiodistal diameters of the teeth were measured at contact points using digital calipers and the Bolton's analysis was carried out on them.

Skeletal maturation evaluation using mandibular second molar calcification stages.

Objective: To investigate (1) the relationships between the stages of mandibular second molar calcification and skeletal maturity; and (2) whether second molar calcification stages can be used as a reliable diagnostic tool to determine skeletal maturity.

Materials And Methods: Samples were derived from panoramic radiographs and lateral cephalograms of 300 subjects (137 males and 163 females) with ages ranging from 9 to 18 years, and estimates of dental maturity (Demirjian Index [DI]) and skeletal maturity (cervical vertebrae maturation indicators [CVMI]) were made.

Results: A highly significant association (C*  =  0.
