AIM To present a unique case of mandibular first and second premolars with two roots and two root canals with the aid of spiral computed tomography (SCT). BACKGROUND Confirmation of morphology of mandibular first and second premolars with the aid of SCT. CASE DESCRIPTION Mandibular premolars usually have a single root and a single canal. The occurrence of two roots with two separate root ca...

Introduction: Congenital missing of maxillary lateral incisors and mandibular second premolars are one of the most common developmental dental anomalies that can affect patient’s function and aesthetics. The aim of this study was to determine the prevalence and pattern of congenital missing of lateral maxillary teeth and second mandibular premolars in patients referred to the Dental Faculty of ...

This ex vivo study evaluated dentin permeability of the root canal in the apical third of different human groups of teeth. Eighty teeth were used, 8 from each dental group: maxillary and mandibular central incisors, lateral incisors and canines, maxillary first premolars (buccal and palatal roots), mandibular first premolars, and maxillary and mandibular second premolars, totalizing 88 roots th...

OBJECTIVE The aim of the present study is to assess the root and root canal morphology of maxillary and mandibular premolars in a Turkish population by using cone beam computed tomography (CBCT). MATERIALS AND METHODS In this study, CBCT images of 2134 premolars (987 maxillary, 1147 mandibular) were obtained from 404 patients. Details of gender, age, number of roots and canals, and canal conf...

introduction: it is essential for clinicians to have knowledge about root canal configuration, although its morphology varies largely in different ethnicities and even in different individuals within the same ethnic group. the current study reviewed the root canal configuration of root canals in mandibular first and second premolars among iranian population based on independent epidemiological ...

Macrodontia is a rare dental anomaly that refers to teeth that appear larger than normal. Generalised macrodontia can be associated with certain medical conditions and syndromes. This case report presents clinical and radiographic findings of isolated bilateral macrodontia in a 14-year-old child. The patient was referred to the clinic with local crowding of maxillary and mandibular teeth. Radio...

A panoramic radiographic study was carried out on 404 dentate Saudi Arabians, to locate positions of the mental foramen. Results show that 83.7% of the mental foramen locations occurred in the interdental space between the mandibular premolars and apical to the mandibular second premolar. 9.35% occurred posterior to the mandibular second premolar, and 6.95% occurred apical/anterior to the mandi...

Surgical approach is considered to be one of the best alternatives in most cases of adult patients with class III malocclusion. Depending on the amount of skeletal discrepancy, surgical correction may consist of mandibular set-back, or maxillary advancement, or a combination of mandibular and maxillary surgery. However, if for various reasons, surgical treatment is contraindicated, orthodontic ...
