Abstract

Introduction: Edentulism impairs the ability to chew, eat, and speak properly. Dentures, which aim to address this issue, are also believed to contribute to a decrease in the peak intensity value and spectral width of sound formants. Formants refer to the air within the vocal tract that is set in vibration by the vocal fold's action. This study aims to observe changes in formant values between complete denture users and participants with complete dentition. Methods: This preliminary study recruited six voluntary participants, divided into two groups. The first group consisted of subjects with complete dentition, while the second group comprised individuals wearing complete dentures on both arches. All participants introduced themselves, and their speech was recorded using PRAAT® software. For the second group, recordings were made both with and without dentures. Statistical analysis was performed using one-way ANOVA. Results: Significant differences in formant scores were observed across all groups. Post hoc tests revealed a significant difference in formant scores between completely edentulous subjects without dentures and the complete dentition group; Conclusion: Correcting speech defects is the third main objective in fabricating denture prostheses. Enhancing the phonetically beneficial construction of denture quality improves psychosocial parameters, including quality of life and socialization abilities, and accelerates successful Prosthodontic treatment. The findings indicate that the format score of a person with a complete denture is not substantially different from that of an individual with complete dentition. Conversely, individuals who have lost their complete dentures and not using complete denture may exhibit significant differences in formant score.

Abstract

Background: Poor bone quality, sometimes caused by osteoporosis, can lead to dental implant failure. Human umbilical cord mesenchymal stem cells (hUCMSCs) can differentiate into osteoblasts and offer an alternative therapy for poor bone conditions. Purpose: This study aims to evaluate the effect of hUCMSCs induction on the extent of osseointegration by the new bone formation area of dental implants in osteoporotic animal models. Methods: The samples were divided into two groups, i.e., control and induced hUCMSCs groups at different times. An ovariectomy was performed to assess the osteoporosis condition. The control group was injected using gelatin, and the treatment group was administered hUCMSCs. Terminations were conducted at 2 and 4 weeks, respectively. The collected samples were then subjected to histological examination to analyze new bone formation and its proportion. In addition, alkaline phosphatase staining was also performed to evaluate the mineralization area. The data was analyzed using the one-way analysis of variance (ANOVA). Results: Both for new bone formation area as well as the proportion of new bone, it was observed that the best results were in the group with induction of hUCMSCs at 2 weeks. Alkaline phosphatase staining also confirmed that the highest mineralization was observed in the same group. Conclusion: hUCMSCs induced new bone formation in the implant placement in osteoporotic animal models.
