Abstract

Objective: This study aims to determine the effect of robusta green coffee gel on the collagen density in Wistar rats. Material and Methods: The subjects were 45 Wistar rats, each wounded with a 3 mm punch biopsy in the mandibular incisor gingiva. The rats were then divided into 5 groups, namely the positive control group (Povidone-iodine 10%), negative control (gel base), and 3 treatment groups (10%, 20%, and 40% concentration of Robusta green coffee gel). The intervention was carried out twice a day. A total of 3 mice in each group were then sacrificed on the 5th and 10th days to see the collagen density using the Mallory Trichrome staining technique. Collagen density was observed using a microscope with 400x magnification in 5 fields of view. Kruskal Wallis test was used for data processing. Results: There was no difference in collagen density regardless of the coffee gel concentration at each observation time, with p>0.05. Conclusion: There was no effect on the times of observation or dose concentration of robusta coffee gel on collagen density on gingival wound healing in Wistar rats.

Abstract

Objective: This study aims to compare the noise level between intraoral suction, HVE, and extraoral suction during anterior tooth preparation in children. B Material and Methods: Noise levels were measured with SPL on manikins, which were separated into four treatment groups, namely saliva ejector, saliva ejector + aerosol suction, HVE, and HVE + aerosol suction. Manikins that were equipped with acrylic teeth were prepared for 3 minutes with a highspeed rotary handpiece, then left to rest for 2 minutes, and the cycle repeated twice for each sample, Results: Descriptive data showed that the noise produced by the suction system is higher than the background noise, with a range varied within 74.7-84.5 decibels. ANOVA test showed a significant difference between the mean noise in the test groups, and Post Hoc LSD showed a significant difference in mean noise in the saliva ejector group against the HVE and HVE + aerosol suction group, and the saliva ejector + aerosol suction group against the HVE and HVE + aerosol suction groups, with p-value <0.05. Conclusion: There is a significant difference in noise level with the additional use of the suction systems during dental treatments, which potentially causes discomfort during pediatric dental care.
