ABSTRACT
AIM AND OBJECTIVE: This study aimed to compare microleakage of resin-modified glass ionomer cement (RMGIC) and alkasite with and without adhesive system in class V cavity. MATERIALS AND METHODS: Thirty class V cavities were prepared on the buccal surface. All prepared samples were randomly divided into three groups. Group I was restored with RMGIC, group II was restored with Cention N after the application of adhesive system, and group III was restored with alkasite. Samples were subjected to 200 thermocycles between temperature baths at 5ºC and 55ºC. Samples were stained with 2% methylene blue. The teeth were sectioned longitudinally, and the sections were then observed under stereomicroscope at a magnification of 20×. RESULTS: Statistical analysis showed that there was less microleakage in Cention N using adhesive system in both occlusal margin and gingival margin. CONCLUSION: There were significant differences between RMGIC, alkasite with adhesive system, and alkasite without adhesive system in class V cavity. Least microleakage at the occlusal margin and gingival margin was seen with Cention N using adhesive system and highest microleakage at the RMGIC. CLINICAL SIGNIFICANCE: Cention N using the adhesive system affects the microleakage in the class V restoration. The study theorizes that the material restorations showed less microleakage in the occlusal margin than in the gingival margin.

This study aimed to explore perceived determinants of condom use behaviors among male clients of female commercial sex workers (FCSWs) in Belu and Malaka districts, Indonesia. One-on-one in-depth interviews guided by the Health Belief Model (HBM) were used to collect the data from participants ( n = 42). The Framework analysis for qualitative data was employed to analyze the data. Results demonstrated several factors associated with lack of and inconsistent condom use among the participants. They included self-perceived risk of contracting HIV infection, knowledge of the severity of HIV illness and its impacts, and condom use: its benefits and its influencing factors. Additionally, factors including reduced sexual pleasure and the lack of knowledge of how and where to access condoms were important perceived barriers to condom use among participants. Having seen images of HIV-/AIDS-positive people, knowing friends and relatives suffering from HIV, and knowing FCSWs as a high-risk group for HIV infection were the cues to using condoms among several participants. Likewise, self-efficacy was also associated with condom use behaviors among the participants. The findings indicate the needs for HIV/AIDS interventions that include dissemination of HIV/AIDS knowledge, condom promotion, and improvement in the availability of condoms for both FCSWs and their clients.
