The objective of this study was to find if there was any relation between the preferred chewing side and the force, measured by T-scan III system. The total number of 90 (46 female and 44 male) dental students was included in this study. They were asked whether their preferred chewing side was right, left or both. Afterwards, the occlusal forces in habitual occlusion, using T-Scan III Electronic device (IP-CO position mode, MA-mode, MA sensitivity setting) were measured. The data were presented as Mean ± SD. Spearman correlation was used to find the correlation between the occlusal force and chewing side. Differences in P 0.05) and the right side (r = 0.143, P > 0.05) according to the preferred chewing side. In this study, the relation between the preferred chewing side and occlusal force was found.展开更多

Based on individual capabilities, visual perception has its disadvantages. The aim of this study was to find out the possible shade difference between the upper and lower teeth, visual perception versus spectrophotometry as well as proving that females are better in visual perception of colour matching. 82 subjects (dental students) of this study determined the color of each other’s natural teeth. The color of 1640 teeth (incisors, canines and premolars), was matched by visual perception and by Vita Easyshade spectrophotometer. The matching was focused on the middle third of buccal surfaces of the examined teeth. In this study, it was found that there was a difference of color between the teeth of the upper and lower jaw. The percentage of the accordance between two methods was 28.35% for all examined teeth. The color determination at central incisors showed the highest value of accordance 40.85%. Based on Vitapan 3D Mastershade, the most frequent color was 2M2.展开更多

Materials and Methods: A randomized split-mouth-design study included twenty-five patients with bilaterally impacted lower third molars (partial or full bone) requiring full thickness mucoperiastal flap reflection for extraction. Following surgical extraction of third lower molar, 2 ml of gel containing 1% chlorhexidine digluconate (Chlorhexamed? Gel 1%) were placed in the experimental side, and saline solution was used for irrigation in the control side of extraction sockets, both followed by suturing of extraction site. The surgeries and follow up examinations were performed by the same surgeon. The follow up visits were performed at 48 hours and on day seven, post surgery where presence or absence of dry socket using the Blum criteria for diagnosis was evaluated and pain intensity by Visual Analogue Scale (VAS) 0 - 100 was observed. Results: In this pilot study, dry socket was present in 4.0 and 28.0% of cases in the experimental and control groups, respectively (P = 0.048). Fisher’s test revealed a statistically significant reduction of dry socket occurrence following the use of 1% CHX gel versus saline solution. Conclusion: The application of CHX gel 1% may significantly reduce the incidence of DS following third molar extraction. Prophylactic use of CHX gel 1% may be suggested in all patients, especially in the patients at risk of development of DS.展开更多
