THE EFFECT OF DENTATE, PARTIAL DENTATE AND NON-DENTATE JAW ON MANDIBULAR MORPHOLOGY- A RADIOGRAPHIC RETROSPECTIVE STUDY
Journal Title: International Journal of Medical Science and Current Research (IJMSCR) - Year 2018, Vol 1, Issue 1
Abstract
Background: Mandible undergoes remodeling and morphological alteration occurs in various parts including the gonial angle, condyle and ramus. This study aimed to evaluate the effect of tooth loss on morphology of the using digital panoramic radiography. Materials and methods: 175 Indian male subjects aged from 25-75 years attending to the dental OPD of SSIMS medical college and hospital, divided in to 3 groups according to the presence of teeth in the mandible; the first group consists of 60 subjects with complete dentition, second group consists of 63 subjects with partial dentition and third group consists of 52 subjects with edentulous mandible. Using digital panoramic image, the condylar and ramus heights and gonial angle were measured on both right and left sides by inbuilt Diacom tracing elements. Results: The mean values of condylar and ramus heights and gonial angle were significant between complete dentition and edentulous groups (p-value<0.001) and between partial0 dentition and edentulous groups (p-value <0.001). For the effect of tooth loss of the mean values of 3 measuring variable i.e. (condylar and ramus heights and gonial angle) among partial dentate group showed; a statistically significant moderate positive linear correlation of condylar and ramus heights with available teeth (p-value<0.001), while gonial angle showed a statistically significant moderate negative linear correlation with available teeth (p-value<0.001) in the same group. Conclusions: The morphology of the mandible changed as a consequence of tooth loss, which could be expressed as a widening of gonial angle and shortening of both condylar and ramus heights.
