Tooth Size Discrepancies in Libyan Class I and II Orthodontic Patients Cross Sectional Retrospective Study
Journal Title: Journal of Advanced Research in Dental & Oral Health - Year 2018, Vol 3, Issue 2
Abstract
Aim: The aim of this study was to determine the prevalence of tooth size discrepancies (TSDs) in Libyan orthodontic population with Class I and II malocclusions. Materials and Methods: From 300 pretreatment sets of orthodontic models at an orthodontic clinic, 52. 26 male 26 were female. were selected (26 Class I and 26 Class II) for adult patient with age less than 25 years (mean 18.1 years; SD ±3.66 The overall and anterior tooth size ratios were calculated. In order to assess the error of the method, 20 study casts were randomly chosen from the sample and remeasured 3 weeks later by the same investigator. One sample t-test was used to compare the mean anterior as well as overall ratio with the original Bolton while two-way analysis of variance (ANOVA) (0.05) was used for comparing the values for both the malocclusion types. Result: No statically significant differences were found for the mean anterior (P = 0.997) as well as for overall ratio (P = 0.768) for both patients with Class I and II malocclusions. The mean anterior and overall ratio were comparable with the original Bolton norm (77.1 and 99.3 respectively). However, clinically significant differences were found for the slandered deviation for both the ratios among the malocclusion group (SD 3.01 for anterior and 3.2 for overall ratio). Conclusion: There were no statistically significant differences among the groups for overall and anterior ratios. Both Class I and II malocclusion groups had discrepancies greater than 2 slandered deviation from the Bolton mean. Further studies are needed with larger sample.
