Abstract

 

  Background and Aims: Tobacco kills 5 million people worldwide annually, according to the Health Ministry reaches this number is about 70,000 people a year in Iran. Dental professionals are in a unique position to promote smoking cessation due to the opportunity for regular interaction with their patients. The aim of this study was to investigate knowledge, attitudes, and skills of dental students at Tehran and Shahid Beheshti dental schools towards tobacco cessation counseling in dental office.

  Materials and Methods: In this cross-sectional study, the target group was dental students at Tehran and Shahid Beheshti dental schools, and the sampling method was census. A questionnaire on the knowledge, attitudes, and skills towards tobacco cessation counseling in dental practice was administered to the students (n=93). Data were analyzed using T-test.

  Results: The response rate was 100% (93 students participate in this program and all of them filled the questionnaire). The average score of knowledge at Tehran and Shahid Beheshti dental schools was 17.5 and 18.4, respectively (P=0.09), the average score of attitudes was 33.5 and 33.1, respectively (P=0.80). There were no significant differences between the two dental schools in these parts. The average score of skill was 11.9 and 16.6, respectively. The differences between the students of two dental schools in skill were significant (P=0.002).

  Conclusion: Although the attitude of dental students at Tehran and Shahid Beheshti schools towards tobacco cessation counseling seemed to be fair, some deficiencies existed in their knowledge and skill. Dental education programs should be implemented properly in this field.

Abstract

  Background and Aims: Hepatitis B is an important infection route in dentistry requiring different disinfectants to prevent its transmission. The aim of this study was to compare the effects of chemical disinfectants (FD366, ISORAPID and 5% sodium hypochlorite 2/100) to remove Hepatitis B infections from the dental surfaces.

  Materials and Methods: In this experimental laboratory trial, serum of 10 HBV patients was poured into microtubes, FD366, ISORAPID and hypochlorite disinfectants were added to them. PCR experiments with viral diagnostic kits were used to diagnose the virus genome. Real time PCR was used to evaluate after incubation with the disinfectants. The reductions occurred in the viral load of Hepatitis B were statistically analyzed using Kruskal-wallis and Mann-Whitney U tests .

  Results: No significant antiviral efficacy was noted following the application of FD366 and ISORAPID disinfectants (P=0/07). However, hypochlorite showed the most efficacy to disinfect Hepatitis B and a significant difference was found among them (P<0.0001).

  Conclusion: Under the study limitations, FD366 and ISORAPID disinfectants did not show adequate efficacy to remove Hepatitis B virus. Hypochlorite was the most effective disinfectant.
