Data are presented on the frequency of the following eight dental traits in 635 Yanomama and 65 Makiritare Indians: upper central incisor rotation or winging, shoveling of maxillary incisors, maxillary molar hypocone reduction, Carabelli's trait, mandibular molar cusp number, mandibular molar cusp pattern rotation of second lower premolar, and pattern of second lower premolar cusps. Yanomama de...

Objective: To evaluate root canal configuration and morphology of premolar teeth among Saudi subpopulations using cone beam computed tomography (CBCT). Material Methods: In this retrospective cross-sectional study, CBCT images 314 patients comprising 346 maxillary 412 mandibular first (FPM) teeth, 298 387 second (SPM) were analyzed to the number roots, morphology, based on Vertucci's classifica...

INTRODUCTION Knowledge of the presence of the alveolar antral artery in the lateral maxillary sinus wall is essential for surgeons who operate in this region. The purpose of this study was to investigate the correlation between alveolar antral artery diameter and lateral maxillary bony wall thickness in dentate patients. MATERIALS AND METHODS Thirty five Cone-Beam Computed Tomography (CBCT) s...

BACKGROUND This study cephalometrically compared the dentoskeletal and soft tissue changes consequent to one and three-premolar extraction protocols of class II subdivision malocclusion treatment. METHODS A sample of 126 lateral cephalometric radiographs from 63 patients was selected and divided into two groups. Group 1 consisted of 31 type 1 class II subdivision malocclusion patients treated...

AIM To present the 14 year follow-up of a case in which an avulsed permanent maxillary central incisor was replaced by autotransplantation of a mandibular premolar. SUMMARY A mandibular premolar (Moorrees' stage 3) was transplanted into the space left by an avulsed permanent maxillary central incisor after a delay of 3 months. Recall examination 14 years after transplantation revealed a norma...

This case report describes an external apical root resorption resulted from the unusual root morphology of the neighbouring tooth. A 28-year-old female was referred to the department of endodontics with a complaint of intense pain in her maxillary second premolar tooth. The clinical and radiographical evaluation revealed an external apical resorption in the mesial root of the maxillary first mo...

This case report highlights the treatment of a skeletal Class II malocclusion with pseudoanodontia that indicated clinical but not radiographic absence of teeth. A 21-year-old female patient presented with a skeletal Class II malocclusion with an orthognathic maxilla and a retrognathic mandible, with Angle’s Class I malocclusion with rotated maxillary and mandibular anteriors with fourteen impa...

Introduction: Anterior middle superior alveolar (AMSA) block is a nerve block technique in conjunction with computer-controlled local anesthetic delivery (CCLAD) system. Anterior middle superior alveolar produces local anesthesia (LA) to the maxillary teeth from second premolar to the central incisor including the hard palate and corresponding soft-tissue of both buccal and palatal side, with s...

OBJECTIVE The aim of this study was to analyze tooth movement and arch width changes in maxillary dentition following nonextraction treatment with orthodontic mini-implant (OMI) anchorage in Class II division 1 malocclusions. METHODS Seventeen adult patients diagnosed with Angle's Class II division 1 malocclusion were treated by nonextraction with OMIs as anchorage for distalization of whole ...
