Comparison of smile esthetics after extraction and non-extraction orthodontic treatment
Journal Title: IP Indian Journal of Orthodontics and Dentofacial Research - Year 2018, Vol 4, Issue 4
Abstract
Introduction Smile esthetics is prime objective of modern orthodontic treatment Effect of tooth extraction on esthetics is controversial Thus the aim of this study was to evaluate and compare the smile esthetics after extraction and nonextraction orthodontic treatmentMaterials and Methods Frontal smiling photographs of 80 orthodontically treated subjects with age range of 1825 years mean age 2016 years were taken and divided into two groups each having 40 subjects GroupI were treated with extraction of all first premolars and GroupII were treated without extraction of teeth Both groups were further divided into two subgroups SubgroupA for male and SubgroupB for female having 20 patients in each subgroup Smile esthetics and esthetic scores were assessed on frontal photographs by using eight transverse and three vertical linear measurements seven derived ratios and four other variables The data so obtained were subjected to statistical analysisResults Statistically nonsignificant difference for all seven ratios were found between Group I and Group II On intergroup comparison of other variables only visible maxillary first molar variable showed statistically significant differences p No significant correlation of esthetic score with all seven ratios was found in the males and females of Group I and Group IIConclusion No difference was found between smile esthetics of extraction and nonextraction subjects Thus decision regarding extraction of teeth in orthodontic patients should not be solely based on smile esthetics but other factors which determine extraction should be consideredKeywords Extraction orthodontic treatment Nonextraction orthodontic treatment Frontal facial photographs Smile esthetics Esthetic score

Comparison of stress distribution in bone and miniscrew and displacement pattern of maxillary anterior teeth by two methods of en-masse retraction: A 3-D finite element analysis
Introduction: To move the teeth in a desired pattern, the appropriate direction of the force must be selected. An inappropriate force delivers unfavourable stresses in the supporting tissues resulting in poor prognosis....
