The effect of temporary hydrostatic splint on occlusion with computerized occlusal analysis system.

Aims: The aim of this study was to evaluate the effect of temporary hydrostatic splint on occlusion with computerized occlusal analysis system. Material and Methods: Maximal bite force was recorded in intercuspal position by use of computerized occlusal analysis system from 11 female, 9 male, 20 subjects, (average age of 20) with normal intact dentitions. Subjects were instructed to use the hydrostatic splint for 24 h. Occlusal records were repeated three times before and after splint. All recordings were evaluated to determine the repeatability of the computerized occlusal analysis system. Results and Conclusion: Hydrostatic splint increased maximum biting force. Relative percentage of left and right bite forces changed in the direction of neurophysiological position of the muscles. Hydrostatic splint can be a viable option for occlusal adjustments.

In vivo efficacy of alkaline peroxide tablets and mouthwashes on Candida albicans in patients with denture stomatitis

OBJECTIVE: Effective cleaning of dentures is important for the maintenance of good oral hygiene for denture stomatitis patients. The in vivo efficacy of three different brands of alkaline peroxide tablets (Polident, Efferdent, and Fittydent) and two mouthwashes (CloSYS II and Corsodyl) to eliminate Candida albicans on dentures was evaluated in this in vivo study. MATERIAL AND METHODS: Ninety denture wearers with clinical evidence of denture stomatitis were randomly divided into 5 test groups and 1 control group. Each group was further divided into three subgroups in which the dentures were subjected to 15-, 30-, and 60-min disinfection procedures. The dentures of each test group were treated with one of the cleaners, while those of the control group were treated with distilled water. Swab samples from the palatal surfaces (2 cm x 2 cm template delimited area) of the upper dentures were obtained before and after 15, 30, and 60 min periods of cleaner use and examined mycologically. RESULTS: The reduction in the number of colony-forming units (CFU) of C. albicans before, and after 15, 30, and 60 min of use of CloSYS II and Corsodyl was significantly greater than that of the control group (p<0.05). Moreover, there was no statistically significant difference (p>0.05) among Polident, Efferdent and the control group in any of the treatment periods. Dentures treated with Fittydent appeared to have a significantly greater reduction in the number of Candida spp. only after 60 min of treatment. CONCLUSIONS: The results of this study showed that the use of mouthwashes significantly reduced the number of microorganisms on dentures.
