Antibakterijsko i antifungalno djelovanje klorheksidin-diacetata ugrađenog u akrilatne smole koje se upotrebljavaju za privremene nadomjestke

Objective: The surface of provisional restorations applied before conventional or implant- supported fixed restorations may cause bacterial or fungal biofilm formation. The aim of this study was to evaluate the antimicrobial activity of acrylic resins used in provisional restorations modified with chlorhexidine diacetate. Methods: 120 cylindrical, auto-polymerized resin samples modified with chlorhexidine diacetate were prepared at concentrations of 0 (control), 1, 3, 5 wt %. The antimicrobial activity was examined against Streptococcus mutans, Enterococcus faecalis, and Candida albicans using Crystal Violet quantification, MTT assay, and Scanning Electron Microscopy. Data were analyzed by ANOVA and paired sample t-tests (α=0.05). Results: The addition of chlorhexidine diacetate influenced the growth rate and metabolic activity of microorganisms. The antimicrobial effect against C. albicans and S. mutans statistically increased with the percentage of chlorhexidine diacetate. E. faecalis bacteria were less affected by chlorhexidine diacetate compared to other pathogens. Conclusion: It has been shown that the effectiveness of CHDA in inhibiting the proliferation of microorganisms correlated positively with increasing concentration levels. More research is needed to confirm the impact of different chlorhexidine concentrations on the mechanical properties, clinical efficacy, and antimicrobial properties of CDHA.Svrha istraživanja: Površina privremenih nadomjestaka koji se koriste prije trajnih fiksnih nadomjestaka ili nadomjestaka postavljenih na implantate može prouzročiti stvaranje bakterijskoga ili gljivičnoga biofilma. Cilj ovog istraživanja bio je procijeniti antimikrobno djelovanje akrilatnih smola koje se upotrebljavaju u privremenim restauracijama modificiranima klorheksidin-diacetatom. Materijal i metode: Pripremljeno je 120 cilindričnih, autopolimeriziranih uzoraka smole modificirane klorheksidin-diacetatom u koncentracijama od 0 (kontrola), 1, 3, 5 težinskih postotaka. Antimikrobna aktinost ispitivana je za mikroorganizme Streptococcus mutans, Enterococcus faecalis i Candida albicans kvantifikacijom Crystal Violeta, MTT testom i skenirajućom elektronskom mikroskopijom. Podatci su analizirani ANOVA-om i t-testom uparenih uzoraka (α = 0,05). Rezultati: Dodatak klorheksidin-dia-cetata utjecao je na brzinu rasta i metaboličku aktivnost mikroorganizama. Antimikrobni učinak kad je riječ o C. albicans i S. mutans statistički se povećavao s postotkom klorheksidin-diacetata. Bakterija E. faecalis bila je manje pogođena klorheksidin-diacetatom u usporedbi s drugim patogenima. Zaključak: Pokazalo se da učinkovitost CHDA-e u inhibiciji proliferacije mikroorganizama pozitivno korelira s povećanjem razine koncentracije. Potrebna su dodatna istraživanja kako bi se utvrdio utjecaj različitih koncentracija klorheksidina na mehanička svojstva, kliničku učinkovitost i antimikrobna svojstva CDHA-e

Information technology in oral health care: Attitudes of dental professionals on the use of teledentistry in Turkey

Telemedicine is transferring medical data between geographically separated areas. There are many application areas and different technologies can be used. Telemedicine has been used in medicine for many years. However, the use of telemedicine in dentistry is very little. Teledentistry has the potential to be a highly effective mechanism for enhancing early diagnosis and to be used in dental education. In a developing country such as Turkey, teledentisty is a necessity for tomorrow. This study aims to determine dental professionals’ attitudes to teledentistry as means of providing consultation, diagnosis, monitoring and dental education in order to introduce teledentistry. An anonymous, selfadministered survey of dental professions in Turkey was conducted by personally meeting each individual. 219 participants comprised dentists, assistants, dental students, technicians and dental educators. The data was analyzed. Descriptive statistics were used to summarize the demographic and survey data. Comparisons between median Likert scale responses were performed using the MannWhitney U test. The authors have developed a profile of current dental professionals in the city of Ankara, i.e. the capital of Turkey. The statistical analyses demonstrate that the majority (80%) of the survey participants considered teledentistry to have potential and reported that it has to be integrated into the current dental practice. Computer use was high in this sample of Turkish dental professionals. The majority of the dental professionals participated stated that the use of teledentistry in monitoring, consultation, and education were favorable
