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.

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.

Aim: To compare the clinical and 3D volumetric socket bone preservation using Beta tri-calcium pohosphate plus collagen (B-TCP/Col) versus Platelet Rich Fibrin (PRF) assessed by 3D cone beam computed tomography. Subjects and Methods: 20 patients were treatment planned for extraction of mandibular and maxillary teeth, leaving 20 sockets for the study. Sockets were divided into 2 groups, each group consisting of 10 sockets. Sockets were grafted as follows: Group (I) sockets were grafted with B-TCP/col, Group (II) sockets were grafted with PRF. Cone beam computed tomography (CBCT) were done immediately and 3 months postoperatively, then collected data were statistically analyzed. Results: After 3 months, Bone height (mm) showed significant difference between the tested groups where Group A (B-TCP) produced the highest mean Bone height followed by Group B (PRF). Bone width (mm) showed insignificant differences between the tested groups. Bone density showed insignificant differences between the tested groups. Conclusion: Beta tri calcium pohosphate plus collagen (B-TCP/Col) may be a adjunctive modality to accelerate bone formation in defective socket.

Objective: To evaluate the effectiveness of the photodynamic therapy (PDT) in comparison with topical corticosteroids upon immune regulatory cells of patients oral lichen planus. Subjects and methods: Twenty patients with clinical and histological diagnosis of EOLP were divided into two equal groups. Group A: (control group) were instructed to use topical corticosteroid, Group B :( study group) received PDT using diode laser 635 nm mediated by toluidine blue (TB), and before starting the treatment five milliliters of peripheral venous blood was taken from both patients groups and withdrawn into an EDTA-containing test tube to prevent coagulation. These procedures were performed after three months and six months of treatment for both topical corticosteroids and PDT treated patients to detect changes occurs before and after treatment. Results: a statistically significant difference was reported between baseline and follow -up periods. Where both groups showed a remarkable reduction in pain, size of lesions, and CD4:CD8 ratio showed statistically significant decrease during follow up periods. Conclusions: Photodynamic therapy is an effective treatment and it can be considered as an alternative method for TC in treatment of erosive-atrophic OLP and effectively regulates the distribution of CD4+ T cells and CD8+ T cells.
