Abstract
BACKGROUND: One of the primary reasons for patient’s to seek prosthodontic treatment is esthetic or cosmetic reasons. The coincidence of dental midline between the maxillary and the mandibular teeth, and the coincidence of dental midline with the facial midline is an important factor governing esthetics. Keeping the above fact in mind the present study was planned to evaluate the relation between facial midline and dental midline and the relation between maxillary and mandibular midline in subjects. AIM OF STUDY: to evaluate the relationship between facial midline to dental midline and also relationship between maxillary to mandibular midline. METHODS: The present study was conducted on 100 Indian male and female individuals of 18 years of age group which included students, staff and patients of Tamil Nadu Government Dental College and Hospital, Chennai. Subjects included in the study were facially symmetrical, had full complement of teeth, healthy periodontium, Angle Class I occlusion, no history of orthodontic treatment and no individual teeth malpositioning. Subjects having any congenital or other facial deformities, badly decayed teeth and restored with crown and bridges were not considered with customised tru byte tooth indicator. RESULTS: Out of 100 subjects in 77, the maxillary midline was coinciding with facial midline, whereas in 23 subjects the maxillary midline was not coinciding with the facial midline. 23 does not coincide with 10 samples of RS (33.5%) and 13 samples of LS (56.5%). CONCLUSION: From the present study and various literature available it is assumed that there is not much difference in population in relation to facial midline and dental midline coincidence and in relation to sex. It can be suggested that when doing arrangement of teeth maxillary dental midline should be co-related to facial midline whereas mandibular midline shift either to right or left to an extent of 1-2.5mm is acceptable.
