Statement of problem. The addition of palatal rugae to complete dentures was suggested to improve the satisfaction of patients with different oral functions. However, there are no clinical studies to confirm these claims. Purpose. The aim of this randomized, single blind, two-period crossover trial was to assess the satisfaction of edentulous patients and their oral health impact profile, when provided with complete dentures with palatal rugae compared to polished palate. Materials and methods.Edentulous patients aged 45-80 years, with no relevant medical conditions, seeking complete dentures at a university hospital between May and July 2019, were recruited. Each participant received a new complete denture. After one-week adaptation period, the participants were randomly allocated to two sequences. In the first sequence, palatal rugae were added to the complete dentures, and after two months, the palatal rugae were removed and the dentures used for another two months. In the second sequence, the opposite sequence was followed; polished palate first, and palatal rugea second. Simple randomization was done through a computer generated sequence. After each period, a blinded dentist asked participants to rate their general satisfaction on a 100-mm visual analogue scale (primary outcome), and to rate their satisfaction regarding eating, taste perception, speaking, phonetics and ease of cleaning. participants were also asked to fill the 20-item oral health impact profile for edentulous patients (OHIP-EDENT). Paired sample t-test and Wilcoxon test were used at 5% significance level.Results. Fifty participants were randomized. Six participants dropped out. No significant differences were found between ratings for the two palatal contours in terms of general satisfaction 2.32 [95%

Objective In this retrospective observational study, we evaluated awareness among patients using bisphosphonates (BPs) regarding the risk of developing medication-related osteonecrosis of the jaw (MRONJ) and whether they received appropriate dental screening and treatment prior to commencing medication. Methods Patients using BPs who attended the endodontics clinic at Jordan University Hospital in 2019 were interviewed using a pre-designed questionnaire. Data were analysed using descriptive statistics and chi-squared tests. Results In total, 110 patients were interviewed (84 women, 26 men; age 40–78 years). A total of 94 patients were using oral BP and 16 received intravenous (IV) BP. We found that only 12.4% of participants were aware about the risk of MRONJ following BP use, and only one third of them has received information from their prescribing physicians. In total, 5% of participants were referred to a dentist for screening prior to initiating BP treatment. Patients receiving IV BP and those with a university-level education had better awareness about the risk of MRONJ than oral BP users and those with a high school education level. Conclusion Patients’ awareness about MRONJ risk was low in our population. Better patient education and collaboration among physicians and dentists are needed prior to starting BP treatment.
