Abstract

Background: Dental caries is a global oral health issue associated with the dominance of Streptococcus mutans in dental plaque. Calcium hydroxide is a commonly used dental material; however, there are increasing concerns regarding its adhesion and dissolution issues. Propolis, a natural compound with antimicrobial properties, promotes fibroblast proliferation, releases antioxidants, and reduces oxidative stress when combined with calcium hydroxide. This combination shows potential for enhancing antibacterial efficacy and pulp preservation in restorative dentistry. Purpose: This study aims to evaluate the antimicrobial effect of a combination of calcium hydroxide and propolis in inhibiting the growth of Streptococcus mutans. Methods: The experimental study assessed the antimicrobial activity of Streptococcus mutans ATCC 25175 using the agar disk-diffusion method. Five treatments with five repetition groups were tested: 2% chlorhexidine (positive control), propolis, calcium hydroxide, a calcium hydroxide-propolis mixture, and saline (negative control). The inhibition zone was measured after 24 hours of incubation at 37°C. Data were analyzed using one-way ANOVA and Tukey's post hoc test in IBM SPSS 25. Results: The positive control (chlorhexidine) showed the largest inhibitory zone (1.488±0.11), followed by propolis (0.862±0.06), calcium hydroxide combined with propolis (0.746±0.05), and calcium hydroxide suspension which suggested the smallest inhibitory zone (0.684±0.09). Conclusion: The combination of calcium hydroxide and propolis demonstrated superior antibacterial activity against Streptococcus mutans only when compared to calcium hydroxide suspension alone.

Abstract

Low back pain (LBP) is a complaint that dentists often encounter because of the tendency to work with static movements for a long duration of time. There are some indicated factors that may involve in the occurrence of the LBP, one of which is the level of physical activity. This study aimed to confirm and understand the association of physical activity level to the incidence of low back pain. The research method was analytical observation with a cross-sectional design. The study used questionnaires on physical activity level and low back pain which were distributed to 76 samples of dentists in the Yogyakarta City area. The data was further analyzed with a chi-square test. The results showed a value of 9.147 with degree of freedom 1 and significance of 0.002. This value is greater than the table's chi-square value of 3.841, which means that there was a significant proportion association between physical activity level and low back pain occurrence
