A Study about Tooth Size and Arch Width Measurement

Abstract

Many model analyses methods for measuring tooth size discrepancies, even though they are not always used have been carried out by many authors and formulated for the predetermination of arch size. On the basis of their findings many studies were carried out to find out its reliability, few researchers agreed to the statement made and few pointed out their lack of agreement. Bolton's method of diagnosing tooth-size discrepancy has been widely used in scientific studies since its publication. Cast analysis is required for all potential orthodontic patients, whether problems are moderate or severe. It is done to evaluate symmetry, alignment (crowding, spacing) and tooth size analysis. His study was done on a French population, the sample size and selection criteria were not described. Pont's analysis Diagnostic records for orthodontic purposeDiagnostic records have been categorized into 3 types 3). Records for intraoral evaluation(1) Intraoral photograph are commonly taken to record any hard and soft tissue lesions.(2) Panaromic intraoral radiograph are taken to see any pathologic lesion, supernumerary or impacted tooth.(3) Bite wing radiographs especially for children and adolescent to evaluate interproximal caries, and for adult to see the periodontal condition.(4) Transcranial and Laminagraphic TMJ films are taken for patients having symptoms of dysfunction.

Applicability of Bolton’s Analysis and Kesling Set-Up- A Study on Chhattisgarh Population

“…We agree with the present study where crowding is significantly related to mesiodistal size of both maxillary and mandibular arches. 30,31 CONCLUSION The Bolton analysis has been shown to be a reliable diagnostic tool for assessing tooth size discrepancy and Kesling diagnostic setup in the treatment planning of dental malocclusions. 9 However, the study has shown that the Bolton's analysis is not only a decisive tool in predicting clinically significant tooth size discrepancies that would prevent from achieving good occlusions.…”

Bolton Tooth Size Discrepancy among Mosul Families

“…It has been found that tooth size discrepancies of the maxillary and mandibular arches is an important factor for achieving this goal. (1)(2)(3) There are many factors that influence the variations in tooth size discrepancy, (4) such as the type of gender: some authors found no significant differences either for Bolton anterior or over all ratios between females and males among different malocclusion groups, (2,3,5) however, others found significant difference in tooth size discrepancy between sexes. (6)(7)(8) It is sug-gested that tooth size discrepancy differs between various racial or ethnic groups, (9)(10)(11) while Endo et al, (12) stated that Bolton's values can be used with confidence for Japanese orthodontic population.…”
