Concurrent presence of a sagittal jaw discrepancy and transverse incompatibility in some cases call for meticulous consideration of three-dimensional nature of the problem. As ort...

Introduction: Bolton ratio is considered as seventh key of normal occlusion. Many orthodontic patients have to undergo premolar extractions as a part of treatment. Aims and objectives: The present study was taken up to investigate the effect of premolar extractions on Bolton's overall ratios in a sample of north Indian population. Materials and met...

Introduction: Skeletal maturation assessment has a great role in many health professions especially in Orthodontics & Dentofacial Orthopedics. Functional appliances have proved to be more effective when used at the peak of mandibular growth, rather than before. Aim: The aim of this study was to evaluate whether the calcification stages of perman...

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. The present article reports the clinical...

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. Samples were derived from panoramic radiographs and lateral cephalograms of 300 subjects (137 males and 16...

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. The sample comprised 150 pretreatment study casts with fully erupted and complete permanent d...

Objective - To find the knowledge of pediatrician regarding preventive dental care in National Capital Territory of Delhi. Method- This study was designed as a telephone survey.
