Malocclusion And Premature Teeth Loss: Its Prevalence And Association Among Yemeni School Children In Sana’a

Abstract

Objectives: This study was conducted in Sana'a city, Yemen to detect the prevalence of early loss of primary teeth and its consequence on malocclusion. Materials and methods: This cross-sectional observational study included 1079 school children aged 7-12 years, and for the detection of the following characteristics, the samples were clinically examined: Angle's classification of malocclusion, anterior open-bite, overjet, lateral open-bite, overbite midline shift and cross-bite. Also, the early loss was classified according to the chronological age of an eruption of the permanent teeth proposed by Kronfeld. Results:The prevalence of malocclusion among school children was 81.1% and the normal first-class molar relationship was found only in 18.9%, while the class I malocclusion included the highest rate of the sample 74%,

Non-extraction Orthodontic Treatment in Angle Class I Malocclusion with Severe Crowding, Deep Bite, and Midline Shifting: A Case Report

Fixed orthodontic appliances are indicated whenever multiple tooth movement is required, e.g., bodily movement, intrusion, extrusion, derotation, controlled space closure at extraction sites, torque control, which were needed by this patient.…”

Evaluation of the Frequency of Primary and Permanent Teeth Extraction in Children at a Dental Hospital: A Cross-Sectional Study
