Fusion and talon cusps are rare developmental dental anomalies affecting both primary and permanent dentitions. Talon cusps normally occur on the palatal surface of permanent maxillary incisors, while fused teeth are more common in the primary anterior dentition. An understanding of these dental anomalies and their associated problems are important to provide prophylactic measures, thereby prev...

Abstract Introduction : Hypodontia refers to the congenital absence of less than six teeth. This may be unilateral or bilateral. Though agenesis bilateral mandibular/maxillary incisors has often been reported in literature, however, mandibular and maxillary incisors, as well second molar-giving rise a total missing permanent teeth an apparently healthy individual not earlier. Case presentation ...

OBJECTIVES This study aimed to assess the radicular wall thickness in mandibular incisors with two canals and find the maximum and minimum thickness to prevent root canal treatment (RCT) procedural errors. MATERIALS AND METHODS A total of 160 extracted mandibular incisors were selected and radiographed; out of which, 55 had two canals. Three parallel transverse sections were made in each toot...

OBJECTIVE To investigate the influence of radiographic film and tube positioning, the presence and the size of brackets on in vitro measurements of proximal enamel thickness of mandibular incisors on periapical radiographs aimed to aid planning of interproximal enamel reduction procedures in orthodontics. MATERIALS AND METHODS Eighty human mandibular incisors were assigned to sets of four and...

OBJECTIVES The aim of this study was to determine the prevalence of root dilaceration in a Turkish dental patient population, considering factors such as dental localization and the relationship between the sexes in this anomaly. STUDY DESIGN A retrospective study was performed using periapical radiography of 2,124 patients, who ranged in age from 15 to 65 years old. All data (age, sex and sy...

OBJECTIVE To evaluate the presurgical orthodontic tooth movement of mandibular teeth after dental decompensation for skeletal Class III deformities on the basis of vertical skeletal patterns. METHODS This cohort was comprised of 62 patients who received presurgical orthodontic treatment. These patients were divided into 3 groups according to their vertical skeletal patterns. Changes in the po...

Aim: To compare two types of treatment for Class II deep overbite malocclusion assessing maxillary and mandibular arches behavior in subjects submitted to full orthodontic treatment with standard edgewise appliance and those who used straight wire appliance. Methods: The sample consisted of 50 patients treated with full fixed appliances either with edgewise appliance (n=25, Group 1), or with st...

This study investigated the early effects on mandibular incisor irregularity and rotation together with dental arch dimensions of the extraction of four deciduous canines. Children, during early mixed dentition, were randomized into one extraction (n = 32) and one control (n = 41) group. Dental casts from baseline (T0) and 1 year follow-up (T1) were used to evaluate changes in the irregularity ...
