ABSTRACT
The objective of the present study was to determine the role of facial mid line as a guide for positioning maxillary dental midline for Prosthodontic patients during fabrication of prosthesis. Furthermore the study will help in indicating character as well as perception of discrepancies between dental and facial midline among Pakistani population. The study was carried out within population of Baqai Medical University Karachi, Pakistan from Jan2013 to June 2013. A total of 500 dentate patients with the age range 18 to 30 years were selected randomly. No fixed proportion was proposed. The patients having permanent dentition from 2nd molar to 2nd molar in maxillary arch were included .However patients having midline diastema, orthodontic treatment, or any cranio-facial anomaly were excluded. The patients were observed to check if the maxillary dental midline coincides with the facial midline. The facial midline was examined by marking points between nasion till pognion including centre of philtrum with the help of scale or dental floss. The results of the present study showed that 82.8% patients had their maxillary dental midline coinciding with facial midline. Therefore it was concluded that the Facial midline can be taken as reliable guide in establishment of maxillary dental midline among Pakistani population
ABSTRACT
The objective of the present study was to correlate the mandible morphology and lower facial height in occlusion through lateral cephalographs. Moreover the cephalometric measurements can be used as records for future complete dentures fabrication. It is a descriptive study and was carried out at the Prosthodontic Department of Lahore Medical and Dental College, Lahore from July 2011 to January 2012. A total of 120 completely edentulous patients of both genders were selected and the age ranged 35 years and above. Demographic data and informed consent of all the patients were taken. The patients with the facial asymmetry, acquired and congenital orofacial deformity were excluded from the study. All those patients not willing to undergo radiography were also not included. The cephalographs of each patient was carried out after the insertion of the complete dentures. The Rickets cephalometric analysis was used to analyze the mandibular shape by [gonial angle] and the mandibular arch. The lower facial height in occlusion was measured by three angles [superior, median, inferior]. The results of the present study showed that there is a positive and a strong correlation between mandibular gonial angle with all the three angles determining the lower facial height. Furthermore the median and inferior angles were found to be having significant correlation with the mandibular arch angle. The regressions for gonial angle [Gonial = 103.527+0.466 [inferior] and for mandibular arch angle [arch =30.519-0.271[superior] +0.227 [inferior] were statistically significant. It was concluded that the mandibular morphology can be used to evaluate the lower facial height in occlusion in the Pakistani population and is complementary to the routinely used methods for the complete denture fabrication
ABSTRACT
Temporomandibular joint has been a subject of intense debate and interest for researchers since long. Temporomandibular disorders are one of the most intriguing and controversial subject in the world of dentistry. This study reviews the possible etiological factors and the management protocol for these disorders. The key to successful management is an appropriate diagnosis, for alleviating pain and restoring physiological functions. The choice of treatment provided to the patient depends on the degree of the problem. On time referral to an oral and maxillofacial surgeon is essential for the treatment of temporomandibular disorders to avoid complications
