A comparison of patient safety culture at two campuses of Riyadh based dental College.

OBJECTIVE: To identify potential shortcoming(s) in relevance to patient safety culture at dental clinics. METHODS: The cross-sectional study was conducted from March to June 2016 at two clinics of a dental teaching college in Riyadh, Saudi Arabia, and comprised subjects who had either direct or indirect contact with patients in the dental clinics. The subjects were handed over a questionnaire based on the Patient Safety Culture Hospital Questionnaire. SPSS 21 was used for data analysis. RESULTS: Of the 149 subjects, 96(64.4%) were male, and 130(87%) were in direct contact with patients, while 19(13%) were in indirect contact. Overall, 52(35%) subjects stated that their unit did not have enough staff to handle the workload, and 71(47.7%) said that not encountering serious errors in their unit was pure luck. An encouraging finding was that 104(69.8%) subjects said their managers appreciated them when they followed the established patient safety protocol. Conclusion: There was a variation in the perception of patient safety culture among professionals.

Dimensional changes in alginate impression during immersion in a disinfectant solution.

OBJECTIVE: To determine the effect of a commercially available disinfectant solution (Perform ID) on the dimensional stability of two different commercially available alginate impression materials. METHODS: Linear changes in standardized impression samples (1.5 mm & 3.0 mm thickness) made in two commercial alginates were recorded at 5 minute intervals, over a period of an hour after immersion in a disinfectant. The alginate impression samples were prepared placing the alginate mixes into a wax mould. After the material had set, each of the samples was removed from the mould. It was then placed in a Polytetraflouroethylene (PTFE) trough before measuring the dimensional changes using a Chesterman travelling microscope. RESULTS: 3mm BluePrint Cremix showed greater shrinkage than 3mm Hydrogum. While, 1.5mm Hydrogum appeared to have uniformly greater shrinkage as compared to 1.5mm BluePrint Cremix. There was significant difference between 1.5 and 3mm thicknesses of both Hydrogum and BluePrint Cremix (PAIRED SAMPLE t test p < 0.05). The 1.5mm samples showed much higher shrinkage than 3mm samples. CONCLUSION: Immersion of the alginates in the same disinfectant showed variable linear shrinkage indicating that slight changes in composition could lead to variable results. In addition, there were significant differences in the linear shrinkage between the two thicknesses of the same alginate material; this indicates the possibility of distortion in actual impressions where the geometry is complex.

Efficacy of antiplaque mouthwashes: a five-day clinical trial.

The aim of this study was to evaluate and compare the efficacy of antiplaque mouthwashes. Plaque levels were determined by applying a plaque-disclosing solution using the Turesky et al modification of the Quigley Hein plaque index. The control group (n = 6) brushed twice per day with fluoride toothpaste for one minute and rinsed with water, while the study groups (n = 6) brushed once per day with fluoride toothpaste for one minute, followed by rinsing with 5.0 mL of mouthwash diluted with 10.0 mL of water for 30 seconds. The control group brushed and rinsed with water twice per day. The results indicated that cetylpyridinium chloride in combination with sodium fluoride offered maximum plaque inhibition, followed by chlorhexidine gluconate and sodium monofluorophosphate, while plaque levels increased in the control group and with the combination of chlorhexidine gluconate and sodium fluoride. The only antiplaque agents to demonstrate a statistically significant difference from the control were cetylpyridinium chloride in combination with sodium fluoride, and chlorhexidine gluconate. Increasing the fluoride concentration had no impact on antiplaque activity.

"Alcohol use in mouthwash and possible oral health concerns".

OBJECTIVE: To establish the presence and quantify Ethanol in commercially available mouthwashes. METHODS: Samples from twelve commercially available mouthwashes were tested for the presence of Ethanol followed by the estimation of percentage of Ethanol in five brands in Pakistan Council of Scientific and Industrial Research (P.C.S.I.R) and Husein Ebrahim Jamal (H.E.J.) labs, Karachi. RESULTS: Ten out of twelve brands of mouthwashes were found to be Ethanol positive. CONCLUSION: Alcohol (Ethanol) in the mouthwashes does not contribute to any therapeutic action. It is alarming to find the presence of alcohol in the mouthwashes which claim to contain no alcohol.
