Materials and methods: Root canal exudates of 30 patients were tested against MTA Fillapex (Angelus), Metapex (BioMed), zinc oxide eugenol (Deepak Enterprise), Endomethasone (Septodont), Endoflas FS (Sanlor Laboratories), MTA (Angelus) (positive control), and glycerine (negative control). Children with failed endodontic cases were included in the study. Tube dilution and agar diffusion methods were used to check the antifungal efficacy of the root canal sealers. In tube dilution method, 24-well culture plates containing freshly mixed material along with Candida albicans were used. Wells containing MTA (Angelus) along with Sabouraud dextrose agar and Candida albicans served as positive control while glycerine along with Sabouraud dextrose agar and Candida albicans served as negative control. All plates were incubated at 37°C for 24 hours. Growth of the fungi was monitored after 24 hours by the presence of the turbidity. The samples were recultured to test the experimental material using agar well diffusion method, and the Petri plates were incubated for 24 hours and 72 hours. Zone of inhibition was measured after respective time period. Paired t test was used for the data analysis.

Results: It was seen in tube dilution method Endomethasone showed least turbidity while maximum was shown by Metapex; similar results were seen in case of agar well diffusion method in which largest zone of inhibition was shown by Endomethasone while smallest was by Metapex.

Conclusion: It was concluded that Endomethasone showed maximum efficacy against Candida albicans as compared to Metapex.

Materials and methods: Clinical and radiographic records of all pediatric patients who had pulpotomy of primary molar teeth between July 2005 and October 2008 were evaluated. A total of 55 pulpotomized primary molars were observed. Clinical assessments were carried out during the second visit to assess the presence of sinus tract, gingival swelling, excessive tooth mobility, tenderness to percussion, and abnormal exfoliation of the treated teeth. Periapical radiographs were reviewed for evidence of pathologic root resorption, radicular and/or periapical radiolucency, and abnormal pulp canal calcification. Treatments were regarded as failure in the presence of one or more of the above clinical and/or radiographic signs and symptoms.

Results: Of 55 pulpotomized teeth, 26 (47.3%) remained free from any clinical signs and symptoms and 48 (87.3%) showed no pathological radiographic findings. The clinical success rates of ferric sulfate and formocresol pulpotomy were 44.4% and 60.0%, respectively, whereas the radiographic success rates of ferric sulfate and formocresol pulpotomy were 86.7% and 90.0%, respectively. Although teeth treated with formocresol had higher both clinical and radiographic success rates compared with those treated with ferric sulfate, it was not statistically significant.

Conclusion: The clinical success rates of pulpotomy were lower compared with radiographic success rates. Ferric sulfate is an alternative to formocresol; however, the use of both agents in the dental undergraduate teaching at Universiti Sains Malaysia can still be recommended.

Clinical significance: Formocresol and ferric sulfate are advocated as pulpotomy agents in primary molar teeth since both agents showed comparable clinical and radiographic success rates.

MATERIALS AND METHODS: This was a cross-sectional study involving final-year dental students from all accredited dental institutions across Malaysia. A self-constructed questionnaire was given through an identified personal contact from each school. The students' responses on the association of sex and institution type with the satisfaction of education activities and ICDAS and ICCMS knowledge were tested using the independent t-test. The relationship between satisfaction of educational activities and knowledge of ICDAS and ICCMS among dental students was evaluated using Spearman's correlation analysis. Statistical significance was set at p < 0.05.

RESULTS: A total of 440 responses were obtained. Out of this, 312 (70.9%) were female and 126 (28.6%) were male respondents, and 2 with unknown sex. There were 231 responses (52.5%) from the private institution and 209 responses (47.5%) from the government institution. Males had a higher level of satisfaction toward the education activities. No significant difference was observed between the knowledge of ICCMS and ICDAS and sex or institution type.

CONCLUSION: Male dental students felt more satisfied with pediatric lectures conducted during preclinical years and were more prepared to treat patients independently upon graduation. Sex and type of institution did not play a role in the knowledge and dental students were more knowledgeable in ICDAS compared to ICCMS.
