Abstract
ABSTRACTAims: To assess the relationship of anterior tooth fractures with type of occlusion and craniofacial morphology.Materials and methods: The study was conducted on 76 subjects of age group 9 to 13 years with at least one fractured permanent anterior teeth. Lateral cephalograms were taken and study models were prepared for each subject with prior consent of their parents. Then cephalometric tracings were done and overjet was recorded through study models.Statistical analysis used: Standard error of mean (SEM) and unpaired t-test has been applied to test the significant difference between the seven parameters under consideration. Karl Pearson correlation test has also been used to correlate all the parameters used in this study with each other. All the tests were performed at 5 and 1% levels of significance.Results: Frequency of tooth fracture increases with increasing overjet. At 5% level of significance, significant difference were observed between the standard values and observed values for overjet measurement, SNA angle, SNB angle, ANB angle, upper incisor to NA (angle), upper incisor to NA (linear) and interincisal angle for overall data and also for both male and female data separately.Conclusion: Probability of permanent anterior tooth fracture increases with increasing overjet. A significant difference was observed between the standard value and the observed values of all parameters under consideration.How to cite this article: Chaturvedi R, Kumar A, Rana V, Aggarwal A, Chandra L.

Highlights
One thousand patients were examined and out of them 76 patients were selected for the study
At 5% level of significance, significant difference were observed between the standard values and observed values for overjet measurement, SNA angle, SNB angle, ANB angle, upper incisor to NA, upper incisor to NA and interincisal angle for overall data and for both male and female data separately
Lateral cephalograms of all the patients were taken by cephalostat machine (Villa Sistemi Medicali, model MR 05 Type 84086500) using 20.3 × 25.4 cm/ ‘8’ × ‘10’ inches film cassettes equipped with Kodak film and intensifying screens (Fig. 2)
