Abstract

Introduction: Root canal treatment is done to maintain the teeth to last as long as possible in the oral cavity. This can be done with three main stages, such as biomechanical preparation, sterilization and root canal filling. The hermetic seal of root canal filling has an important role in the success of root canal treatment. Objective: The aim of this in-vitro study is to compare the microbial leakage of root canals filled with RealSeal sealer/Resilon Points and AH Plus sealer/conventional gutta-percha points using single cone obturation technique and warm vertical compaction technique. Methods: Thirty-two extracted human mandibular premolars with single canals were decoronated to a standardized root length of 15 mm and prepared using crown-down technique to a master apical file size 30/.09. Teeth were divided into four experimental groups (n = 7 each group) and controls (n = 1 each group). Teeth in the first group were obturated using single master gutta percha cone and AH Plus sealer and second group were obturated with single Resilon gutta percha cone using RealSeal sealer. Third experimental group was filled with warm vertical condensed gutta-percha using AH Plus sealer and fourth group was filled with warm vertical condensed Resilon gutta-percha using RealSeal sealer. The coronal chamber of each sample were inoculated with Enterococcus faecalis. Results: There were no significant differences between the four experimental groups (P = 0.182). The differences occurred only in the survival time from each group. Group 4 (Warm Vertical Condensation - RealSeal) has the lowest leakage rate among other groups and the fastest leakage occurred in group 1 (Single Cone - AH Plus). Conclusion: The single-cone techniques does not insure durable apical seal against bacterial leakage. Warm vertical compaction technique using Resilon gutta-percha and RealSeal sealer appears to be more effective in minimizing bacterial leakage than gutta-percha and AH Plus sealer.

Abstract

Today, cardiovascular disease is the second biggest cause of mortality worldwide, after cancer. In urban communities, bicycle communities are also activated by an awareness of the significance of staying fit through exercise, particularly cycling. Nonetheless, sports can also trigger health issues, such as heart attacks or cardiac arrest due to fatigue or exhaustion. Numerous common individuals are unfamiliar with the terms basic life support and cardiopulmonary resuscitation, and hence lack the confidence to assist victims. Method. On 19 June 2021, 30 members of the Bikelah community attended a presentation and video screening regarding Basic Life Support. Result: Following an explanation of the Basic Life Support material, the respondents' perception and knowledge of the adoption of BHD increased from 60% to 93%, and their willingness to assist an unconscious victim similarly increased from 53% to 90%. Respondents also had a better understanding of the significance of assisting an unconscious victim prior to the arrival of medical personnel. Conclusion. Because the period of chance to avoid brain cell damage is brief, victims might benefit from basic knowledge and abilities in Basic Life Support. The goal for the future is to deliver mannequin-based training to the broader population.

Abstract

Background: Nanofilled resin composites are popular for their aesthetics but are vulnerable to discoloration and surface degradation, particularly in acidic environments. Gochujang, a Korean chili paste, is increasingly consumed and may affect dental restorations. Objectives: To evaluate the effect of gochujang sauce immersion on the color stability and surface roughness of nanofilled resin composite. Methods: Thirty-three Filtek™ Z350 XT A3 samples were divided into three groups (n=11): immediate control, distilled water control, and gochujang treatment. The treatment group was immersed daily in a 1:1 gochujang-distilled water solution (16 h) and distilled water (8 h) for four days at 37°C. Color change (ΔE) was measured with a VITA Easyshade V spectrophotometer; surface roughness (Ra) with a Taylor Hobson Surtonic S-100. Results: Gochujang immersion significantly increased color change (ΔE, p<0.001) and surface roughness (Ra, p=0.009) compared to controls between groups (p<0.05). Conclusion: Gochujang immersion adversely affects both color stability and surface roughness of nanofilled resin composites.
