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

Abstract

BACKGROUND Orthodontic treatment planning poses significant challenges for clinicians with respect to their ability to provide the most predictable results for patients in a safe, effective and efficient manner. Prediction of accurate space has prime role in diagnosis and treatment planning in Orthodontics. Aims and Objectives-The aim of the study was to determine whether the mean overall and anterior ratio of Chhattisgarh population would significantly differ from Caucasian (Bolton's) values. To evaluate extraction as a parameter in determination of Bolton ratio and compare it with non-extraction case while using Kesling diagnostic setup. MATERIALS AND METHODS The sample was screened from the general OPD of Department of Orthodontics and Dentofacial Orthopaedics, Maitri Dental College, Anjora, Durg as well as from the students of Maitri Dental College. Camps were set up in Maitri Nursing College and students diagnosed with orthodontic problems and various other ailments were called to the OPDs for treatment. Patients who were able to cooperate, having complete permanent dentition (first molar to first molar), no caries, no proximal restoration, no attrition and no dental anomaly. All teeth should be fully erupted to the occlusal plane. Patients having at least anterior crowding were included. 33 extraction and 67 non-extraction cases were included. RESULTS Standard descriptive statistics (mean, standard deviation and standard error of mean) were calculated for each sample. Comparison was made between the extraction and non-extraction subjects, and also between the present established overall ratio and anterior ratio. 'T' test was used for comparison of extraction and non-extraction and comparison was made between Bolton's study (Caucasian population) and recent study (Chhattisgarh population). 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.
