Extensive literature underscores the significance of HA in maintaining tissue water balance, fostering cell proliferation, promoting rapid cell migration, influencing cell differentiation during organism development, and facilitating tissue regeneration. Notably, HA’s interactions with cell surface receptors contribute to the viscosity of synovial fluid, activate the immune system, and enhance cartilage elasticity. Beyond these established functions, HA has also been investigated for its potential involvement in determining and studying the hormetic effects of radon water, adding a novel dimension to its applications in dental research. A thorough exploration of existing studies reveals a nuanced understanding of how HA interventions impact the outcomes of dental procedures. The comprehensive scope of these investigations allows for a more accurate assessment of the potential effectiveness of specific interventions and provides valuable insights into post-procedural prognoses for individual patients. This synthesis of literature serves as the foundation for elucidating the intricate interplay between HA, radon exposure, and their relevance in modern dental practices.展开更多

The aim of this study was to contribute to improving the processing conditions of reusable care instruments in dental practices in the city of Conakry. Methods: We carried out an observational and cross-sectional study of a descriptive type lasting three months from January to April 2022 in public and private dental practices approved for activities. Results: A total of 48 dental practices were surveyed, including 7 public and 41 private. 91.67% had the trays for instrument sterilization. 77.08% had a sterilization device. The instruments were: cleaned 100%, disinfected 70.83%, sterilized 20.83% and 20.83% reused the instruments without being sterilized. 72.97% sterilized the instruments at the end of the day. 50% of respondents declared that there were six stages of sterilization. According to standard standards, one dental office or 2.70% respected the normal sterilization process and 13.51% respected the duration and temperature. The storage quality was inadequate at 95.83%. 95.83% of dental practices are at high risk of contamination. The difficulties encountered by staff in daily activity during our study were lack of hygienists (87.50%), insufficient material resources (58.33%), and lack of protocol procedure (45.83%). Conclusion: This study allowed us to note shortcomings of dental surgeons in the process of processing reusable care materials.展开更多
