Objective: To investigate the regeneration of rat's salivary gland diabetic defect after intraglandular transplantation of Human Dental Pulp Stem Cells (HDPSCs) on acinar cell vacuolization and Interleukin-10 (IL-10). Material and Methods: HDPSCs isolated from the dental pulp of first premolars #34. HDPSCs from the 3rd passage was characterized by immunocytochemistry of CD73, CD90, CD105 and CD45. Twenty-four male Wistar rats, 3month-old, 250-300 grams induced with Streptozotocin 30 mg/kg body weight to create diabetes mellitus (DM) divided into 4 groups (n=6); positive control group on Day-7; positive control group on Day-14; treatment group Day-7 (DM+5.105HDPSCs); treatment group on Day-14. On Day-7 and Day-14, rats were sacrificed. Histopathological examination performed to analyze acinar cells vacuolization while Enzyme-linked Immunoabsorbent Assay to measure IL-10 serum level. Data obtained were analyzed statistically using multiple comparisons Bonferroni test, Kruskal Wallis, Shapiro-Wilk and Levene's test result. Results: The highest acinar cell vacuolization found in control group Day 14 (0.239 ± 0.132), meanwhile the lowest acinar cell vacuolization found in treatment group Day 7 (0.019 ± 0.035) with significant difference (p=0.003). The highest IL-10 serum level found in treatment group Day 14 (175.583 ± 120.075) with significant difference (p=0.001). Conclusion: Transplantation of HDPSC was able to regenerate submandibular salivary gland defects in diabetic rats by decreasing acinar cell vacuolization and slightly increase IL-10 serum level.

Background: Complete dentures can improve the quality of life of edentulous patients. The selection of a suitable articulator and an impression technique is important to construct a stable and retentive complete denture with good occlusion. The use of a semiadjustable articulator ensures that the dentures can be constructed such that their movement closely resembles the patient’s physiological movements. The effective suction method can ensure the development of the border seal according to the patient’s anatomical condition. The use of a semi-adjustable articulator along with an effective suction method is expected to provide good results in the construction of a complete denture. Purpose: This report aimed to describe the management of individual complete dentures in the flat mandibular ridge using a semi-adjustable articulator along with an effective suction method. Case: A 69-year-old female patient came with a chief complaint of her old dentures being unusable and wanted new dentures made. The patient’s general condition was good, and the last extraction was done three months prior to the patient’s arrival. The mandibular posterior alveolar ridge showed dextral tapering and sinistral flatness. Case Management: A complete denture with an acrylic base was fabricated using a semi-adjustable articulator along with an effective suction method. Conclusion: Flat ridge case management using a semi-adjustable articulator with an effective suction method can improve complete denture retention and stability.

Aims: The aim of this study was to analyze the induction effect of a combination of N. sativa and bovine bone graft on the expression and ratio of receptor activator of nuclear factor kappa-B ligand expression (RANKL) and osteoprotegerin (OPG) on alveolar bone socket preservation on days 7 and 14. Settings and Design: The research incorporated a posttest-only control group design. A total of 56 Cavia cobaya were divided into four groups: a control group, an N. sativa group, a bovine bone graft group, and a combined N. sativa and bovine bone graft group. Materials and Methods: The lower incisors of the C. cobaya were extracted with material subsequently being applied to the resulting socket. After the 7th and 14th days, the experimental animals were terminated to enable observation of the socket. Following processing, the tissue was subjected to immunohistochemistry staining consisting of RANKL and OPG antibodies before being observed under a light microscope at × 400. Statistical Analysis Used: Statistical analysis was carried out using the one-way ANOVA and Tukey’s honestly significant difference tests. Results: A combination of N. sativa and bovine bone graft reduced both RANKL expression and the RANKL/OPG ratio while increasing OPG expression in comparison to the other groups. In all the results obtained, the N. sativa and bovine bone graft combination was significant (P < 0.05) when compared to the control group on both the 7th and 14th days. Conclusion: A combination of N. sativa and bovine bone graft reduced both RANKL expression and the RANKL/OPG ratio while increasing OPG expression.
