BACKGROUND We identified the most useful variables for prediction of difficult laryngoscopy in patients with cervical spondylosis according to physical indicators and preoperative skeletal X-ray and soft tissue MRI measurements. We hypothesized that there was a closer association between difficult laryngoscopy and radiologic indicators. METHODS We randomly enroled 315 patients undergoing elec...

PURPOSE The purpose of this project was to establish median eruption ages of primary teeth and evaluate eruption differences between contralateral teeth by gender, ethnicity, and household income. Data was derived from a caries study of preschool children. METHODS A total of 4,277 white (non-Hispanic) and Hispanic preschool children from Arizona were visually examined for caries and tooth eru...

This article describes the treatment provided to a patient with the maxillary anterior teeth exhibiting severe secondary caries beneath the previous restoration and a white spot lesion on the adjacent incisor. Two implants were placed after extraction of hopeless teeth with the guided bone regeneration technique. A white spot lesion of the adjacent incisor was treated with minimally invasive tr...

Agenesis of one or more teeth is the most common anomaly in dental development.1 The incidence for permanent tooth agenesis ranges from 1.6 to 9.6% in the general population excluding third molars.2-6 Third molars being the most commonly missing tooth, opinions vary on the second most commonly missing tooth. Some investigators7-11 believe that this is the maxillary lateral incisor whereas other...

Background & Aims: Iron deficiency anemia is the most common kind of anemia in childhood. Iron supplements that are usually prescribed for the treatment stain teeth. The purpose of this study was an in vitro comparison of the adsorption rate of iron onto incisor primary teeth after exposure to three different Iron drops (Darupakhash, Fer–In– Sol, Shahredaru). Methods: This study was performed o...

UNLABELLED Lower incisor extraction in orthodontic treatment was very rare modality of orthodontic treatment because there are few patients who meet the standards for such treatment. Proper diagnosis and treatment planning should be done to achieve good occlusion and facial esthetics. Criteria for lower incisor extraction included degree of crowding, tooth size discrepancy, pathologic condition...

OBJECTIVE This study was designed to define the Korean norm values for the Ricketts analysis. METHODS In this longitudinal study, lateral cephalograms of 31 subjects with normal occlusion were taken biennially from ages 9-19 years. Cephalometric measurements were performed. Parameters for which the 10-year change did not exceed one standard deviation were defined as unchanged. The means and s...

Abstract Introduction: Prosthetic restorations in the frontal teeth, addition to functional and prophylactic requirements, must respond a special way aesthetic needs. This desideratum is challenge, especially when support for future prosthetic parts not characterized by uniformity of color. paper wants highlight importance color abutments, case single restorations, teeth. Case presentation: man...

T he orthodontic literature abounds with speculation on the etiology of incisor crowding as a late (postpubertal) growth phenomenon. Lombardil cites most of the prominently considered factors in his survey of the literature: tooth discrepancies, arch size, interference of canines in lateral excursive movements, overbite, overjet, tooth removal, incisor-mandibular plane angle, type of original o...

OBJECTIVE Mandibular incisor extraction in carefully selected cases as an alternative option to four bicuspid extraction or non extraction treatment has been advocated. The purpose of this study was to determine the degree of improvement in occlusion in patients with Bolton discrepancy treated by one lower incisor extraction using Peer Assessment Rating Index (PAR indexes). MATERIALS AND METH...
