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, ...

ABSTRACTIntroduction Caries initiation is associated with demineralization of the toothenamel surface. Calcium and phosphorous are lost from subsurface enamel, resultingin formation a lesion. Aim: this study aimed to investigate comparethe enamel surface ultramorphology minerals content by Environmental ScanningElectron Microscope (ESEM) Energy dispersive x-ray spectroscopy (EDX) toassess micro...

This article describes a method to treat Class II malocclusions with no patient cooperation. The technique involves converting the Class II molar relationship to a Class I in the initial phase of treatment by moving the maxillary molars distally with superelastic coils and wire. Anchorage is provided by a transpalatal bar attached to the first premolars and connected to 2 palatal miniscrews. On...
