This research aimed to investigate the differences in the sealing capability of propolis extracts and Ca(OH) 2 on dentin surfaces. Materials and Methods: Eighteen mandible incisors of Wistar rats were prepared at a depth of 0.5 mm after which they were randomly divided into 3 groups (n=6) including control (C), pulp-capped with Ca(OH) 2 group (P1), and indirect pulp-capped with propolis extract group (P2). All the cavities were sealed with glass ionomer restorative cement. Moreover, the sections of the teeth were obtained after six Wistar Rats from each group were sacrificed on the second day after treatment. The rats' incisors were cleaved transversally to the area where Ca(OH) 2 and propolis extract bonded with dentin for the SEM (scanning electron microscope) analysis and examined using microphotographs test with 5000x magnification. All the samples were measured and examined with spectrophotometry test to determine the bonding distance between Ca(OH) 2 and dentin, as well as propolis extract and dentin. The result from the two tests was analyzed with SPSS using an independent t-test at p <0.05. Results: There were significant differences between the calcium hydroxide and propolis extract groups (p<0.05) based on the results obtained in the form of spectrums chemical functional groups of spectrophotometry examination. No new chemical bonding or compound was also observed to have been formed between propolis extract with dentin as well as calcium hydroxide with dentin. Conclusion: The adaptation or sealing capability of propolis extract was found to be better than calcium hydroxide to the dentin surface.

Background: Dental caries is one of oral and dental disease that has high prevalence in Indonesia. The fact showed that there are many dental caries were in advanced condition, resulting in root canal treatment needed. The failure of root canal treatment usually caused by patient non compliance in multivisit treatment. It was probably because of the lack of public knowledge about oral and dental health. Purpose: This study was to investigate the correlation between oral and dental health knowledge with patient compliance in multivisit treatment. Methods: An analytic survey using cross sectional design was carry out on 35 patients in UPF Konservasi Gigi RSGMP FKG UNAIR around September-November 2011. The data gathering was done using both questionnaire and focused interview. The test of Spearman correlation was used to measure the correlation between the oral and dental health knowledge to patient compliance in multivisit treatment. Result: This study showed that there was no significant correlation between oral and dental health knowledge to patient compliance (p=0,837). But there was significant correlation between patient compliance with patient motivation  (p=0,006), needs (p=0,020), perception (p=0,018) and dental treatment cost (p=0,034) with patien compliance in multivisist dental treatment. Conclusion: There was no significant correlation between oral and dental health knowledge to patient compliance. There are other factors that give significance contribution to the increasement of complianced beside knowledge, such as motivation, needs, patient’s perception in continousy treatment and and cost.
