Objective:To evaluate the antibacterial and antifungal properties of calcium-based cement, Biodentine (Ca3SiO2), compared to commercial glass ionomer cements (GICs) and mineral trioxide aggregate (MTA).Materials and Methods:Pellets of GICs, ProRoot MTA, and Biodentine were prepared to test the influence of these cements on the growth of four oral microbial strains: Streptococcus mutans, Enterococcus faecalis, Escherichia coli, and Candida albicans; using agar diffusion method. Wells were formed by removing the agar and the manipulated materials were immediately placed in the wells. The pellets were lodged in seeded plates and the growth inhibition diameter around the material was measured after 24-72 h incubation at 37°C. The data were analyzed using analysis of variance (ANOVA) test to compare the differences among the three cements at different concentrations.Results:Test indicates that the antimicrobial activity of Biodentine, on all the microorganisms tested, was very strong, showing a mean inhibition zone of 3.2 mm, which extends over time towards all the strains. For Biodentine, GIC, and MTA, the diameters of the inhibition zones for S. mutans were significantly larger than for E. faecalis, Candida, and E. coli (P < 0.05).Conclusion:All materials showed antimicrobial activity against the tested strains except for GIC on Candida. Largest inhibition zone was observed for Streptococcus group. Biodentine created larger inhibition zones than MTA and GIC.
Mucosal fenestration is an opening or an interstice through the oral mucosa. A lesion which occurs with greater frequency than generally realised, its occurrence is attributed to a myriad of causes. Mucogingival procedures including connective tissue grafts, free gingival grafts and lateral pedicle grafts are generally considered to be the treatment of choice in the closure of a mucosal fenestration. More often, these procedures are performed in conjunction with other procedures such as periradicular surgery and with bone grafts. However, the concomitant use of gingival grafts and bone grafts in mucosal fenestrations secondary to infections in sites exhibiting severe bone loss is highly debatable. In this article, we report two cases of mucosal fenestrations secondary to trauma and their management by regenerative periodontal surgery with the placement of guided tissue regeneration membrane and bone graft. The final outcome was a complete closure of the fenestration in both the cases.
A variety of treatment modalities, from removable partial dentures, fixed prosthesis to implant placement can be used for replacement of missing teeth. Anterior diastema closure is one of the most challenging tasks; it is appreciable that restorative approach is the fastest, simplest and most predictable. This case report presents a successfully accomplished closure of diastema in mandibular anterior teeth, and splinting of the adjacent teeth which were grade II mobile. This present treatment modality offers a conservative, aesthetic and non-invasive treatment which can be considered as a long-lasting treatment.
Objectives: The main aim of this survey was to collect data regarding the rate at which the new technologies are used in endodontic practice.Methods: A detailed questionnaire was circulated to 500 delegates in Federation of Operative Dentistry and Indian Endodontic society conference. The delegates were requested information about specific materials and techniques used. 319 delegates responded which accounts for 63.8% of response.
Results:The survey results reflect improved technology. 14% prescribe medication prior to the treatment and Amoxicillin was most frequently preferred antibiotic. 84% of responded dentists use Sodium hypochlorite as intracanal irrigant. 81% use Ca(OH) 2 as an intracanal medicament. 95% of dentist still use hand files in cleaning and shaping of the canals. Crown down technique was most preferred way used in biomechanical preparation. Lateral Condensation technique was used for obturation, 36% of people use digital radiography, 26% prefer single visit endodontic treatment.Conclusion: With the review of the result of the survey states that there are vast changes in present day endodontic practice as new materials and techniques are incorporated in routine endodontic practice. This is to conclude the result should serve as a baseline for comparative purpose for future surveys.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
