Abstract

Background: Losing teeth as a result of tooth extraction is a concern since it can affect speech impairment, temporomandibular junction (TMJ) dysfunction, masticatory dysfunction, and psychological disorders, specifically aesthetics. A fixed denture or a removable denture must be made to replace missing teeth in order to preserve the quality of life of the patient. Purpose: to describe the improvement in oral and dental health knowledge that resulted from dental health education about how to care for dentures in the nursing home. Methods: The data collection was done by two surveyors. The sample size for this study was 50 individuals over the age of 50. Under the direction of Jagir Health Centre, Pelangi and Lestari nursing home to educate the elderly about the instruction on how to take care of dentures. For the pre- and post-tests, the participants were required to complete a questionnaire in order to assess how their knowledge of oral and dental health had changed. Results: The presentation on oral and dental health education was mostly grasped by the participants. In comparison to the pre-test rate (58%), the post-test percentage (98%) was higher. Conclusion: This study showed that enhancement of elderly awareness of their oral and dental health condition through dental health education was a successful approach.

Abstract

Background: Immediate complete overdentures are designed for placement denture immediately following the extraction or decapitation of natural teeth. This procedure overcome the challenges associated of esthetic problems, including functional difficulties and psychological issues. Purpose: The article aims to highlight the advantages of endodontic-prosthodontic approach through immediate overdenture, such as the preservation of alveolar bone and improvement in patient’s psychological well-being and quality of life. Case: A 60-years-old female came into Universitas Airlangga Dental Hospital with the chief complaint of missing multiple teeth with upper front teeth becoming loose and desire to replace them because of difficulty in chewing food. Case Management: Diagnostic impressions were taken using irreversible hydrocolloid material, then poured in the dental stone to create final impression. The treatment plan included endodontic treatment, scaling and root planning for 11. The vertical dimension of occlusion was established using a bite rim and mounted on an articulator. Then, the immediate overdenture was created by arranging artificial teeth. Before the denture insertion, 11 was decapitated and filled the orifice with glass ionomer cement. Extraction of 21, 22, 23 was carried out and after ensuring hemostasis, the immediate overdenture was inserted. To finalize the denture insertion, occlusion was assessed using articulating paper. Control was done after day 1,3 and 7 after denture insertion. Conclusion: This case report describes the effectiveness of immediate overdentures as a valuable treatment option through endodontic-prosthodontic approach. By providing a functional and aesthetic solution while minimizing the edentulous period, immediate dentures significantly enhance patient’s quality of life.

Abstract

Tooth extraction can lead to alveolar bone resorption, requiring regenerative approaches using biomaterial scaffolds combined with stem cells. Chitosan–hydroxyapatite (CS–HA), a well-established scaffold that mimics the composition of human bone, combined with stem cells represents a promising strategy to promote bone formation. This study aimed to evaluate the effect of chitosan–hydroxyapatite (CS-HA) scaffolds seeded with cryopreserved human adipose-derived mesenchymal stem cells (hADMSCs) on bone sialoprotein (BSP) secretion. The hADMSCs used in this study were commercially obtained cryopreserved cells (ATCC® PCS-500-011™) and were characterized by flow cytometry. Scaffolds were fabricated using a freeze-drying method by combining chitosan and hydroxyapatite in a 1 : 1 ratio, followed by freezing at −80 °C. A post-test-only control group design was employed, consisting of 36 samples divided into three groups: positive control (CS-HA + hADMSCs + a-MEM), negative control (hADMSCs + osteogenic medium), and treatment (CS-HA + hADMSCs + osteogenic medium), and BSP levels were subsequently quantified on days 7, 14, 21, and 28 using ELISA. One-way ANOVA demonstrated a significant difference among groups (p = 0.000), with the highest BSP secretion observed in treatment group on day 14 (BSP levels 44.29 ± 2.58), followed by treatment group on day 28 (BSP levels 46.19 ± 7.64).  The significantly elevated BSP secretion in the treatment group on day 14 demonstrates osteoinductive characteristics of the CS-HA scaffold, supporting its potential application in bone tissue engineering and regeneration.
