BACKGROUND Cleft lip and/or palate is the most frequent congenital abnormality occurring in the craniofacial region and is often associated with numerous dental defects such as tooth agenesis, supernumerary teeth, microdontia, taurodontism, crown malformations, or delay in eruption. The prevalence of hypodontia in cleft-affected patients is much higher in comparison with a healthy population. T...

INTRODUCTION We investigated the root canal configuration of maxillary premolars in a Spanish population by using cone-beam computed tomography. METHODS Images of 804 maxillary first and second premolars were obtained from 620 patients who underwent cone-beam computed tomography scanning during preoperative assessment (before implant surgery, orthodontic treatment, dentoalveolar trauma diagno...

Background: The most commonly impacted teeth are the third molars, maxillary canines, maxillary central incisors and premolars. Impacted premolars may lead to aesthetic concerns, masticatory inefficiency and oral hygiene difficulties as well as follicle pathology and destruction of adjacent structures, including neighboring teeth, the purpose of this study to shade light on the prevalence of im...

BACKGROUND Mixed dentition space analysis forms an important part of orthodontic diagnosis and treatment planning. Regression equations are widely used for mixed dentition analysis which can vary among races. This study aimed to find out the new regression equation in estimating the size of unerupted canines and premolars for Nepalese Brahmins/Chhetris. METHODS Hundred Nepalese Brahmins/Chhet...

1. Isolate and etch the facial and buccal surfaces of the lower central incisors and first premolars. 2. Using a light-cured adhesive, bond ceramic brackets* with posts for elastic placement directly to the lower first premolars. Position the posted brackets on the mesial contours of the premolars to minimize unwanted rotations, tilting them slightly to the mesial to make elastic placement easi...

Introduction: Endodontic failure may arise mainly from persistent intra-radicular infection from remaining bacteria in the root canal. As a result, retreatment is the most appropriate way of dealing with failed cases. However, many clinicians choose to perform periapical surgery, on the grounds that it is simpler and has immediate results. The resected teeth with insufficient root canal treatme...

The published literature contains no comprehensive studies that compare the outcome of premolar autotransplantation to the maxillary anterior region with natural incisors in the same patients. This article describes the gingival and periodontal conditions around premolars transplanted to the maxillary incisor region, subsequent to restoration. Forty-five premolars autotransplanted to the maxill...

Abstract Background The objective of this study was to use CBCT look into the root canal morphology maxillary premolars in a Saudi Arabian subpopulation and associate results existing classifications. Methods sample size for analysis 500 right left untreated first second with fully formed roots from 250 residents (125 male 125 female). following observations were made using on teeth related: (1...

The prevalence of dento-alveolar anomalies in the structure dental morbidity ranks third position following caries and periodontal diseases. Signs normal teething are following: timeliness, sequence relation to certain groups teeth, evenness, eruption teeth first lower jaw then upper jaw. timing for deciduous permanent can shift one direction or another. There is a distinction between premature...

STATEMENT OF PROBLEM Dimensions of teeth have been available for a century. Some significant and clinically relevant aspects of dental esthetics, however, such as the crown width/length ratios, have not been presented in tooth morphology sources until recently. PURPOSE The purpose of this study was to analyze the anatomic crowns of 4 tooth groups (central incisors, lateral incisors, canines, ...
