A BSTRACT Background and Objectives: It has been found that the microorganism behind the failure of root-filled teeth is Enterococcus faecalis , which shows resistance to most of the intra-canal medicaments. Therefore, the purpose of this study was to evaluate the antibacterial efficacy of three intra-canal medications—calcium hydroxide with saline, combinations of calcium hydroxide with 2% chlorhexidine (CHX), and calcium hydroxide with 5% povidone-iodine—against E. faecalis in dentinal tubules of human incisors. Materials and Methods: Forty permanent maxillary central incisors were made into standardized segments and infected with E. faecalis . They were treated with a paste made of calcium hydroxide and 2% CHX, calcium hydroxide and 5% povidone-iodine, and calcium hydroxide and saline for 1 week. Dentinal shavings collected from the canal were suspended in thioglycollate broth solution and spread on brain heart infusion agar. Colony-forming units (CFUs) were enumerated and the CFU per milligram of dentin was calculated. The pH of the medicaments used was measured with the help of pH meter. Results: The results showed that the paste made from calcium hydroxide and 2% CHX was significantly more effective than that made from calcium hydroxide and povidone-iodine, and calcium hydroxide and saline. The addition of CHX or povidone-iodine did not affect the alkalinity of calcium hydroxide. Conclusion: This study concludes that Ca(OH) 2 + 2% CHX are effective against E. faecalis . Combinations of calcium hydroxide and 5% povidone-iodine showed better antibacterial effect than calcium hydroxide and saline. Ca(OH) 2 + saline was ineffective against E. faecalis .
Background: The aim of the study is to compare the erosive potential of three different commonly used pediatric syrups on deciduous teeth enamel. The objectives of the study were to assess the endogeneous pH and titratable acidity of mefenamic acid syrup (meftal P), cetrizine syrup (alerid) and multivitamin syrup (zincovit) and to evaluate the microhardness of the enamel after successive immersion cycles in each of the syrups.Methods: 40 non carious deciduous teeth were included for the study The samples were then randomly allocated into 4 groups (10 in each group): Group A- mefenemic acid syrup (meftal P), Group B- cetrizine syrup (alerid), group C- multivitamin syrup (zincovit) and group D- control (distilled water). The samples were then subjected to the immersion cycles in the syrups. Assessment of enamel surface microhardness was done using Vickers hardness tester at 7th day and 14th day. The pH and titrable acidity of the syrups were also assessed. One way analysis of variance (ANOVA) and post hoc tests were used for the statistical analysis.Results: Out of the test groups, group C showed the lowest pH of around 4.2 and exhibited the largest titrable acidity (22.8 ml) compared with 21 ml in group A and 15.5 ml in group B. At the end of 14th day, group A had microhardness of about 293.43.84±6.34, group B had 299.930±6.85, group C had 313.380±6.23 and group D had 334.190±5.51.Conclusions: All the pediatric liquid medications assessed in the study, meftal P, alerid and zincovit showed acidic pH, high titrable acidities and all the syrups showed loss of microhardness after exposure to the syrups for 14 days. Loss of microhardness was highest for meftal P followed by alerid and least for zincovit.
Aim To discuss about the possible treatment modalities of supernumerary tooth in place of a impacted permanent tooth Background Numerical anomaly with an excessive number of teeth are termed as supernumerary teeth. Case description This paper describes a case with erupted supernumerary tooth in the place of missing left maxillary central incisor. Radiographically the left maxillary central incisor was impacted below the root of the supernumerary tooth with an additional impacted supernumerary tooth in relation to the right maxillary central incisor. Conclusion A multidisciplinary approach is required in managing the supernumerary teeth. When orthodontic extrusion of the impacted permanent tooth is not possible the possibilities of retaining the supernumerary tooth should be considered. Clinical significance This paper describes about the treatment of supernumerary tooth erupted in the place of missing left maxillary central incisor not amenable for orthodontic extrusion.
