Previous studies have suggested methods for predicting third molar tooth eruption radiographically. Still, this prediction is associated with uncertainty. The aim of the present study was to elucidate the association between cephalometric measurements on profile and panoramic radiographs and to find a simple and reliable method for predicting the eruption of the mandibular third molar by measur...

OBJECTIVE To explore how many millimeters of tooth size discrepancy (TSD) are clinically significant, to determine what percentage of a representative orthodontic population has such a tooth size discrepancy, 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 comp...

BACKGROUND The objective of this retrospective case-control study was to measure the maxillary lateral incisor root dimensions and quantify the labial and palatal bone in patients with unilateral maxillary lateral incisor agenesis (MLIA) after orthodontic treatment and compare them to non-agenesis controls using cone beam computed tomography. METHODS The labiopalatal and mesiodistal root dime...

introduction: a study model is a precise three dimensional replica of patient’s dentition and plays an important role in treatment planning. many digital multi-media applications have become available to the clinician and his or her staff to facilitate standard procedures in practice and management. the aim of this study is to evaluate reliability and validity of dental measurement made on digi...

Study background: Bolton Index is one of the most commonly used analysis in order to evaluate tooth-size discrepancy. Even if this measure could represent an important tool in clinical practice, many Authors questioned its widespread applicability. The aim of this study was to compare the anterior and total tooth width ratios of an orthodontic population with the Bolton standards and analyse di...

Selection of anterior teeth depends mainly on Leon William theory that hypothesizes the presence of harmony between the face and inverted central incisor forms. If this theory is approved mathematically then the central incisor form and width could be predicted and calculated with acceptable precision in clinical practice. The purpose of this study was to predict the tooth form and mesiodistal ...

Orthodontic treatment comprises different phases with unique characteristics and challenges. The orthodontic "finishing" phase is recognized for the multitude of details necessary to achieve an excellent result. In some cases, the finishing phase is very difficult, requiring the production of complicated biomechanical forces to reach a satisfactory orthodontic solution. A high percentage of the...

OBJECTIVE To determine the differences in various linear and angular measurements between erupted and impacted lower third molar group on conventional panoramic radiographs. METHODS The quasi-experimental study based on non-probability convenience sampling and done at the National Institute of Oral Diseases, Karachi, comprised 140 patients having full dentition with bilaterally present mandib...

background and aims. the aim of this study was to determine whether variations in the mesiodistal dimensions of mandibular canines had any role in sex determination. materials and methods. the study comprised of patients in the 19‒24-year age group (20 males and 20 females). mesiodistal dimensions of mandibular canines was measured at the maximum mesiodistal width, first intraorally, then on pl...
