Abstract
INTRODUCTION: India is composed of diverse ethnic groups and to do an acceptable orthognathic surgery treatment planning for every group of people is important. This study is a cross sectional study which is a gateway to conclude upon the normal hard tissue values of Tamil Nadu population. These values will give an edge in diagnosis and treatment planning for this prestigious population. 1931 Angles orthodontics - Broad Bent BH, introduced Roentgenographic cephalometry, mainly as a tool to study craniofacial growth and development. Since that time cephalometric analysis have been routinely used to determine the relationships of the dentofacial complex. Cephalograms also helps to determine the changes associated with growth and treatment3.Facial appearance is of prime concern, and hence more people are opting for orthognathic surgery. The successful treatment of the orthognathic surgical patient is dependent on careful diagnosis and planning. Cephalometric analysis can aid in the diagnosis of skeletal and dental problems and is a tool for simulating surgery and orthodontics. AIMOF THE STUDY: Is to study and compare, the cephalometric hard tissue profile values and analysis between Tamil and Caucasian population. OBJECTIVES: 1. To create a better understanding in the facial proportions of Tamil nadu population. 2. To have better diagnosis and treatment planning for orthognathic surgery for Tamil population in Tamil nadu. MATERIALS AND METHODS: This study was conducted in Ragas Dental College & Hospital Chennai Tamil Nadu. The patients and their attendants who reported to Ragas Dental College & Hospital in the period between 1s t November 2008 to 31s t October 2010 were selected. Sample constituted 54 individuals which included 28 males and 26 females with age ranging from 18 to 35 years were enrolled for the study consecutively who met inclusion and exclusion criteria. They were selected on the basis of their class I molar occlusions and well balanced facial profile. The adults of Tamil Nadu origin residing in Tamil Nadu were included in the study. Lateral cephalograms were taken for each subject included in study with their consent. A prestructured proforma was used to collect the relevant information and record cephalometric measurements for each subject. RESULTS: The present study was undertaken in the Department of Oral and Maxillofacial Surgery, Ragas Dental College & Hospital, Chennai. 54 individuals (28 males and 26 females) with age ranging between 18 to 35 years were enrolled for the study consecutively. They were selected on the basis of their excellent occlusions angles class I molar relation and well balanced facial pattern. The patients who reported to Ragas Dental College & Hospital, Chennai in the period between 1s t November 2008 to 31s t October 2010 were selected. Sample constituted adults of Chennai origin residing in Tamil nadu. Lateral cephalograms where taken for each subject. Various angular and linear measurements for hard tissues in both males and females were obtained and were tabulated. All the reading thus obtained were subjected to statistical analysis. Mean, standard deviation and range values were determined for the total sample, male and female groups. The mean and standard deviations of each group and the values originally obtained by Burstone and Legan were subjected to a students t-test using Microsoft Excel program and the level of significance was set at 0.05. SUMMARY: The present study was undertaken in the Department of Oral and Maxillofacial Surgery, Ragas dental college and hospital, Chennai. Evaluation of cephalometric analysis for orthognathic surgery for hard tissue for ethnic Tamil population was done on 54 volunteers between 1s t November 2008 to 31s t October 2010 were Selected. The study was conducted with two objectives. Firstly, to determine lateral cephalometric standards of Tamil nadu adult with balanced facial esthetics and normal occlusion using the Burstone comprehensive cephalometric analysis that are specific for orthognathic surgery. Secondly, to compare the mean value of soft and hard tissue measurements obtained with normative standards given by Burstone. There was significant difference in the measurements of given Tamil nadu population and norms for Tamil population was determined. Table 6 shows hard tissue norms. These readings can be used for ethnic Tamil population who is undergoing orthognathic surgery.
