However, degradation of adhesive dentine interface remains largely responsible for the relatively short lifetime of tooth colored resin restoration. The aim of the study is to compare the dentin collagen stabilization property of Chlorhexidine (CHX) and Aloe barbadensis Miller using shear bond strength testing. Occlusal reduction was done in sixty extracted human mandibular molars to expose the mid coronal dentin and divided into three groups n = 20. Following the surface pretreatment (Group 1 = control, Group 2 = CHX, Group 3 = Aloevera), dentine bonding agent and composite resin were applied and cured. The specimens were then subjected to shear bond strength testing. From the results analyzed, it was noted that there was statistically significant difference between the groups Control and CHX and Control and A. barbadensis Miller (P < 0.05), specifically the values of Control < CHX and Control < A. barbadensis Miller (P < 0.05). However, there was no statistically significant difference between CHX and A. barbadensis Miller (P > 0.05). Hence, the following result for the shear bond strengths to dentin was obtained: Control < CHX ≈ A. barbadensis Miller. CHX and A. barbadensis Miller, as pretreatment agents of acid demineralized dentin collagen, has no adverse effect on the immediate shear bond strength of a two-step etch and rinse adhesive to dentin.

Cross sectional and observational studies have been included, which are mostly retrospective. A comprehensive search was performed in the Systematic Electronic Databases, PUBMED and MEDLINE from 1919 till September 2014. Articles were also hand searched. From 86 studies identified, all were read and 58 articles which were relevant were included in the text. Some articles were excluded because they were pertaining to periodontology and other systemic disorders. Some were solely animal studies and were thus excluded. Our results suggest an independent association between cardiovascular diseases and apical periodontitis. A causal relationship could not be established since weak parameters of risk have been assessed in the studies, population taken is difficult to compare and other confounding factors have not been ruled ou...

Materials and Methods: Agar plates were prepared using tryptone soya agar. Cultures of E. faecalis were grown in tryptone soya broth. Agar well diffusion method was performed and the plates were incubated at 37°C for 24 h. The zones of inhibition were recorded. The readings were subjected to statistical analysis using analysis of variance (ANOVA) and Tukey's post hoc test. P-value was considered significant at P < 0.05. Results: Maximum antibacterial efficacy was exhibited by 2% CHX, followed by 5% NaOCl and C. longa with no statistically significant difference between them. It was followed by M. alternifolia (Tea tree oil). Ethanol and saline showed the least antibacterial action. Conclusion: According to the results of this study, C. longa and M. alternifolia can be used as an alternative root canal irrigant, although long-term in vivo studies are warranted.

Enterococcus fecalis is the most common micro-organism isolated from failed endodontic cases. The constant increase in antibiotic resistant strains and side effects caused by synthetic drugs has prompted researchers to look for herbal alternatives since the gold standard for irrigation i.e., sodium hypochlorite (NaOCl) has many disadvantages. Objective: The present study was aimed to explore newer irrigation solutions, which would probably be as effective as NaOCl. Materials and Methods: Extracted human single rooted premolar teeth were biomechanically prepared, vertically sectioned, placed in tissue culture wells exposing the root canal surface to E. fecalis is grown on Mueller Hinton agar plates to form a biofilm for 6 weeks. At the end of 6 th week, all seven groups were treated with 3 ml of test solutions and control for 10 minutes and evaluated for E. fecalis growth and number of colony forming units. Results: Propolis, NaOCl and triphala showed no statistically significant difference, whereas all the other inter-group differences were statistically significant (Tukey's honest significant difference (HSD)) (P < 0.001). Conclusion: Propolis and triphala were found to be as efficacious as NaOCl. The use of herbal alternatives as root canal irrigation solutions might prove to be advantageous considering several unfavorable properties of NaOCl.

Since only 7-27% of such teeth develop pulp necrosis with radiographic signs of apical periodontitis, it is difficult to decide whether to treat these teeth immediately upon detection of the pulpal obliteration or to wait until signs and symptoms of pulp and/or apical periodontitis occur. This article reviews the etiology, prevalence, classification, mechanism, diagnosis as well as treatment options for teeth with pulp obliteration and the various management approaches and treatment strategies for overcoming potential complications. A search of articles from "PubMed" and "Medline" from 1965 to present was done with the keywords dental trauma, discoloration, pathfinding instruments, pulp canal obliteration, and root canal treatment was conducted. A total of 94 abstracts were collected, of which 70 relevant articles were read and 31 most relevant articles were included in this article.

The emphasis currently is being laid upon new technologies for enamel remineralization. Further studies are required on biomimetic molecules involved in calcium fluoride phosphate stabilization and nucleation that may provide further improvements in the development of novel remineralization treatments. The aim of this paper is to review the contemporary remineralizing systems available for remineralization therapy and their implementation into clinical practice. A search of articles from "Pubmed" and "Medline" with the keywords Remineralization-demineralization, Casein derivatives, fluoridated remineralizing agents and non-fluoridated remineralizing agents was conducted. A total of 810 abstracts were collected, of which 351 articles that discussed the current technologies of remineralizing agents were read and 71 most relevant articles were included in this paper.

Candida albicans is the most common fungus isolated from failed endodontic cases. The constant increase in antibiotic resistant strains and side-effects caused by synthetic drugs has prompted researchers to look for herbal alternatives such as propolis, Morinda citrifolia and Azadirachta indica (Neem) etc., since, the gold standard for irrigation, i.e., sodium hypochlorite has many disadvantages. Materials and Methods Materials and Methods: Extracted human mandibular premolars were biomechanically prepared, vertically sectioned, placed in tissue culture wells exposing the root canal surface to C. albicans grown on Sabouraud Dextrose Agar to form a biofilm. At the end of 2 days, all groups were treated with test solutions and control for 10 min and evaluated for Candida growth and number of colony forming units. The readings were subjected to statistical analysis using analysis of variance and post hoc Tukey tests. Results Results: Sodium hypochlorite and propolis groups exhibited highest antimicrobial efficacy against C. albicans with no statistically significant difference. It was followed by the A. indica (Neem) group. M. citrifolia had limited antifungal action followed by the negative control group of saline. Conclusion Conclusion: According to the results of this study, propolis can be used as an effective antifungal agent similar to that of sodium hypochlorite, although long-term in vivo studies are warranted.
