Effect of inter-premolar width on buccal corridor area show during posed smile

Orthodontic diagnosis and treatment planning is in a period of remarkable change, away from a previous focus on dental occlusion and hard tissue relationship and towards a greater emphasis on soft tissue adaptation and proportions. The re-emergence of the soft tissue paradigm in clinical orthodontics has made smile analysis and designing, key elements in treatment planning. Hence the purpose of this study was to establish the correlation between one of the many variables effecting smile; the inter-premolar width with the buccal corridor area show of a patient during posed smile. 147 dental casts and frontal photographs were obtained and measured for the inter-premolar width and buccal corridor area show. SPSS version 10 was used to calculate mean and SD for age [in years], inter-premolar width and the inter-commissure width of subjects. Frequencies and percentages were calculated for gender. Pearson correlation coefficient was determined for the inter-premolar width with the buccal corridor area show. r value was determined between -1.0 and +1.0The p value for inter-premolar width and buccal corridor area show during posed smile was < 0.05 being significant. It was concluded from the study that there is a statistically significant relationship between inter-premolar width and the buccal corridor area show during posed smile

Pre-clinical operative dentistry: students viewpoints

The aim of the study was to evaluate the pre-clinical operative dentistry course from a student's viewpoint in order to monitor the academic environment and give recommendations for improvement. A questionnaire was completed by second year dental students on the last lecture day of the year. The questionnaire consisted of questions evaluating different aspects of the course. 46 out of 50 students completed the questionnaire. The course was considered by almost all to be of benefit. Opinion was divided regarding formal assessment in the final professional examination. Quality of teaching was reported to be good although teaching sessions were perceived to be disorganized and prone to repetition. Exercises on plaster models were widely condemned. Improvements in pre-clinical teaching can be brought about by a more structured course, adding more topics and assigning more faculty to supervise the exercises

Level of pain experience of patients during endodontic treatment procedures in the Islamic international dental college

To report the pain experienced by the patient during the endodontic procedure and correlate this-with age and gender of the patient, tooth type, arch, pulpal diagnosis and stage of endodontic procedure. Eighty five patients with ages ranging between 8- 60 years who reported to the Islamic International Dental College for endodontic treatment were consecutively selected. A 10-point visual analogue scale [VAS] was used to rate the level of pain suffered during the treatment session. The mean pain score was 1.75 for all patients with a mean of 1.33 for men and a mean of 2.38 for women. 50.5% of patients reported no pain; severe pain occurred in only 6[7.1%] of patients. No significant correlation was found for age but the pain experience of patients aged 50 and above was less. Obturation procedures were the least painful with access cavity preparations resulting in the greatest number of patients experiencing severe pain. Pain experienced during endodontic procedures is greater during access cavity preparation [51.7%] and canal preparation [64%]. Sever pain was more reported for female patients, posterior teeth and teeth with pulpitis
