Abstract

Background: Root canal treatment is an effort to maintain the function and aesthetics of teeth. The smear layer is formed from the remains of instrumentation composed of organic and inorganic components. A smear layer in the tooth root canal will benefit the adhesion and colonization of microorganisms, block the action of disinfectant solutions, and prevent medicaments in the tooth root canal from penetrating the dentin tubules in the tooth root canal walls. Irrigation can be used for cleaning and disinfection in areas of the root canal that cannot be reached using instruments. Starfruit contains alkoloids, saponins, tannins, flavonoids, phenols, and triterpenoids. Objective: To determine the effectiveness of star fruit extract (Averrhoa bilimbi L) as a smear layer cleaning agent. Materials and Methods: This researcher used laboratory or experimental testing called Post Test Only Control Design. Samples were taken using the purposive sampling technique involving four treatments and six repetitions. The statistical test used is the Mann-Whiteney test. Results: Based on the Mann-Whiteney test, the test results obtained a p-value of 0.093 which is more significant than 0.05 (p-value 0.05). The results showed no significant difference between the 17% EDTA and 35% extract treatment groups regarding smear layer cleanliness. The 35% extract group is as good as the 17% EDTA group. Conclusion: star fruit extract (Averrhoa bilimbi L) is 35% effective in cleaning the smear layer.

Abstract

Abstract Background.The attitude and belief of groom and bride candidates on exclusive breastfeeding were still low. Objective.This study aimed at examining the effect of exclusive breastfeeding module on the attitude and belief of groom and bride candidates at Tarakan City. Method. This study applied quantitative approach with pre-test post-test. The subjects of this research were groom and bride candidates who attended pre-marriage counseling at Ministry of Religion office of Tarakan City where the number of sample were 100 respondents. The distribution of exclusive breastfeeding module was done after pre-test to measure the groom and bride candidates’ attitude towards exclusive breastfeeding. The data analysis was done using T-test of Paired Samples Test. Findings. The characteristics of male respondents in Module Reading group were generally aged from 25 to 30 years old (52%) and those who belonged to Lecture Listening group were generally aged from 20 to 24 years old and 25 to 30 years old (32% and 32%). Female respondents in Module Reading group and Lecture Listening group were generally aged from 25 to 29 years old (40%) and 20 to 24 years old (56%). The attitude and belief of the male respondents in all groups after intervention were, in general, statistically meaningful to the value of p<0.05. The attitude of female respondents in module reading group was not meaningful while the belief of female respondents in Lecture Listening group was also not meaningful. Conclusion Health Education can improve the attitude and belief of male respondents on exclusive breastfeeding while the attitude and belief of female respondents in all groups were different from the male respondents’ after the intervention. It is suggested that exclusive breastfeeding materials are given to groom and bride candidates. Key words: Attitude and Belief, Groom and Bride Candidates, Exclusive Breastfeeding

Abstract

Background: Skipjack tuna (Katsuwonus pelamis) bone waste in South Sulawesi has high potential as a natural hydroxyapatite (HA) source due to its calcium–phosphate content. However, the effect of precipitation duration on HA yield and phase composition remains unclear. Research Objective: To evaluate the effect of precipitation time (12, 24, 36, and 48 hours) on hydroxyapatite yield and phase composition from skipjack tuna bone. Methods: Experimental laboratory study using precipitation method. Bone-derived CaO was reacted with 0.6 M H₃PO₄ under controlled pH using NaOH 1 M. The precipitate was aged for 12–48 hours, dried, calcined, and weighed to determine yield. Phase composition was analyzed using XRD. Results: The highest yield was obtained at 24 hours (97.807%). Longer durations (36 and 48 hours) reduced yield. XRD showed Whitlockite dominance at 12 hours (84.5%), increased Hydroxyapatite at 24 hours (46.1%), Whitlockite re-dominance at 36 hours (50.4%), and Fluorapatite dominance at 48 hours (49.7%). Conclusion: A 24-hour precipitation time produced the highest HA yield with balanced phase composition. Prolonged precipitation altered mineral phases and reduced efficiency.
