Aim: The purpose of this study was to determine the prevalence of denture stomatitis and study the associated factors in complete denture wearers among residence of Aljouf Region, Saudi Arabia. Materials and methods. Two hundred fifty-six complete denture wearers participated in this cross-sectional study. Patients were recruited from Outpatient clinics, College of Dentistry, Aljouf University. Associated factors such as age, gender, income, level of education, denture-wearing at night, Length of denture use, frequency and method of denture cleaning were studied. All data were obtained by intra-oral examination. Bivariate correlation (Spearman Rho), crosstabs descriptive analysis and frequency analysis were performed. The prevalence rate of denture stomatitis was determined and the associated factors were statistically analyzed. Results. The prevalence of denture stomatitis was 23.4 % (60 patients). There was a statistically significant relationship between the prevalence of denture stomatitis with age, Level of education, Length of denture use, denture wearing at night, frequency and method of denture cleaning (p < 0.05). There was no significant relationship between the prevalence of denture stomatitis with gender and income of the patient. (p > 0.05) Conclusions. The presence of denture stomatitis in complete denture wearers was strongly related to patient age, level of education, denture wearing at night, frequency and method of denture cleaning.

This study evaluated dental implant stability, vertical bone gain, bone density, and crestal bone loss using different crestal sinus lift techniques (osteotomy, Densah burs, and piezosurgery). A total of 21 patients were randomly divided into three groups: Group 1: patients were treated using a Densah drill crestal sinus lift, Group 2: patients were treated using a piezoelectric crestal sinus lift and Group 3: patients were treated using an osteotome crestal sinus lift. The patients in all three groups underwent bone grafting and implant placement. An Osstell device was used to determine the implant stability by recording the values of the implant stability quotient (ISQ). CBCT was performed before and 6 months after implant placement for radiographic evaluation and comparison among the groups. All dental implants were completely successful, and statistically significant differences from baseline to 6 months were noted in all groups (p < 0.05). The Densah burs technique resulted in the best implant stability of all groups, while the osteotome technique demonstrated better vertical bone augmentation. However, the values for bone density and crestal bone loss showed no significant difference among all treated groups (p > 0.05). All three techniques were successful for crestal sinus lifts with good clinical outcomes at a 6-month follow-up. The Densah group demonstrated better implant stability, shorter surgery time, and fewer complications; however, the vertical bone gain was greater with the osteotome technique.

be managed with multispecialty team. Constant follow-up and optimal time to start the reconstructive management depend upon a disease-free state of atleast 4 months.

Piezoelectric surgical instruments with various mini-sized tips and cutting technology offer a precise and thin cutting line that could allow the wider use of periodontal osseous wall swaging. This randomized controlled trial was designed to investigate the use of a minimally invasive piezo knife to harvest vascularized interseptal bone pedicles in treating intra-bony defects. Sixteen non-smoking patients (mean age 39.6 ± 3.9) with severe chronic periodontitis were randomly assigned into one of two groups (N = 8). The Group 1 (control) patients were treated by bone substitute grafting of the intra-bony defect, whereas the Group 2 patients were treated by intra-bony defect osseous wall swaging (OWS) combined with xenograft filling of the space created by bone tilting. In both groups, the root surfaces were treated with a neutral 24% EDTA gel followed by saline irrigation. Clinical and radiographic measurements were obtained at baseline and 6 months after surgery. The sites treated with osseous wall swaging showed a statistically significant probing-depth reduction and increase in clinical attachment compared with those of the Group 1 patients. The defect base level was significantly reduced for the OWS group compared to that of the Group 1 control. By contrast, the crestal bone level was significantly higher in the OWS group compared to Group 1. The crestal interseptal bone width was significantly higher in Group 2 at 6 months compared to the baseline value and to that of Group 1 (<0.001). The osseous wall swaging effectively improved the clinical hard- and soft-tissue parameters. The use of mini inserts piezo-cutting, sequential bone expanders for osseous wall redirection, and root surface EDTA etching appears to be a reliable approach that could allow the use of OWS at any interproximal dimension.

Objective: the objective of this study was designed to evaluate the effect of non-surgical periodontal therapy on glutathione levels in saliva and gingival crevicular fluid among diabetics with chronic periodontitis. Subjects and Methods: A total number of 60 patients were selected consists of three groups: group 1 was 20 patients with healthy periodontal condition, group 2 was 20 patients with chronic periodontitis and group 3 was 20 diabetic patients with chronic. Scaling, root planning and oral hygiene instructions were performed for patients in group 2 and group 3.Saliva and GCF samples were collected from each subjects at baseline (before treatment) , one month and three months after performing the non -surgical periodontal therapy. Results: Following non-surgical therapy, glutathione levels in diabetic and chronic periodontitis groups improved significantly when compared to base line levels.No significant correlation between glutathione, age and disease activity in diabetic & periodontitis groups. Conclusion: Glutathione levels should be considered a marker for disease and the concentration of reactive oxygen species in human body and an important indicator for the progression of the periodontal treatment in patients with periodontal disease.

This in vitro study compared the shear bond strength (SBS) and antibacterial efficacy of an orthodontic adhesive containing either cinnamon or titanium dioxide (TiO2) nanoparticles (NPs). A total sample of 120 freshly extracted teeth was randomly divided into three groups, according to the type of NPs incorporated into adhesive for metallic orthodontic brackets’ bonding: group 1—conventional orthodontic adhesive (TXT) as a control; group 2—conventional orthodontic adhesive mixed with TiO2 NPs (TXT + TNP); and group 3—conventional orthodontic adhesive mixed with cinnamon NPs (TXT + CNP). The SBS and adhesive remnant index (ARI) scores were evaluated and compared between the groups. The antibacterial efficacy against Streptococcus mutans for all the groups was assessed via a disc agar diffusion test. Data comparisons among groups were performed by ANOVA followed by Bonferroni post hoc test. Antibacterial efficacy comparison between the experimental groups was performed via an independent t-test. The significance level for all the tests was set at p ≤ 0.05. The highest mean SBS values (10.11 ± 1.88 MPa) were in the TXT control group followed by TXT + TNP (9.40 ± 1.78 MPa), and the lowest SBS was in the TXT + CNP (8.99 ± 1.77 MPa) group. The mean SBS among the experimental groups was non-significant (p = 0.241). Antibacterial effects significantly increased (p ≤ 0.05) in both experimental groups. However, TXT + TNP revealed a significantly higher antibacterial effect (p = 0.021) than TXT + CNP. In conclusion, incorporating cinnamon or TiO2 NPs into an orthodontic adhesive improves its antibacterial effects without compromising the bond strength for clinical purposes.
