The influence of Azadirachta indica, Melaleuca alternifolia, and Cocos nucifera on Candida albicans strain in tissue conditioner at varying time intervals.

AIM: The search for alternative therapies for oral candidiasis is a necessity and the use of medicinal plants seems to be one such promising solutions. Incorporation of phytotherapeutic agents, Azadirachta indica (neem oil), Melaleuca alternifolia oil (tea tree oil), and Cocos nucifera oil (coconut oil), were tested for their efficacy as antifungal agents against Candida albicans. Next, the efficacy of these three antifungal agents when incorporated in a soft relining material at minimum inhibitory concentration (MIC) was evaluated. SETTINGS AND DESIGN: Evaluative - In-vitro study design. MATERIALS AND METHODS: The MIC against C. albicans ATCC 24433 was calculated for M. alternifolia oil, A. indica oil, and C. nucifera oil using the broth microdilution method. Based on the preliminary screening results for MIC, tissue conditioner samples were prepared to evaluate the zone of inhibition (ZOI) and MIC. Antifungal activity of the MIC of the three oils was assessed and compared by measuring the mean ZOI. Antifungal activity of the three oils was assessed using one-way analysis of variance (ANOVA) and post hoc test. STATISTICAL ANALYSIS USED: Oneway ANOVA and post hoc Tukey honestly significant difference test. RESULTS: Inhibition against C. albicans was exhibited when 20% v/v, 25% v/v, and 15% v/v of C. nucifera oil, M. alternifolia oil, and A. indica oil were used, respectively. The results of ANOVA and post hoc test at the end of 48 h and 7 days suggested that all three oils were significantly different from each other (P = 0.000) and A. indica/neem oil with 15% concentration had the best antifungal activity at the end of 48 h and 7 days. CONCLUSION: The antimycotic activity of M. alternifolia, C. nucifera, and A. indica mixed with the Visco-gel tissue conditioner can be used as an alternative therapy for denture stomatitis.

Barotrauma: Tooth under Pressure.

With the growing number of air passengers, flight attendants, leisure pilots, as well as military and airline pilots, dentists may encounter physiological and pathological phenomena precipitated by high altitude. With the introduction of the self-contained breathing apparatus (SCUBA), many of these manifestations caused by changes in atmospheric pressure were reported in association with diving as well. Limited literature exists on this subject. Hence, this article aims to review literature concerning the classification, etiology and manifestations of barodontalgia, as well as important clinical considerations for its management.

Bilateral implant-retained auricular prosthesis for a patient with congenitally missing ears. A clinical report.

Microtia is a major congenital anomaly of the external ear. It includes a spectrum of deformities from a grossly normal but small ear to the absence of the entire external ear. These deformities account for three in every 10,000 births, with bilaterally missing ears seen in fewer than 10% of all cases. Congenital abnormalities of the ear are unlikely to result in the complete absence of the ears, but the patient presented in this article had bilateral congenitally missing ears. There was loss of anatomic landmarks and alteration of normal bony architecture. Minimal tissue was available for retention; therefore, conventional techniques could not be used for achieving retention. A two-implant-supported auricular prosthesis was planned, but the patient was found to have deficient bone in the implant site. Hence the implants were placed posterior to these sites, and the superstructure was modified to accommodate for this change in position of the implant to ensure the esthetic positioning of the prosthesis.

Crowns to create esthetics for mal-aligned central incisors: a case report.

This case report describes the smile design of crowded upper central anteriors in a female patient aged 25 years. The patient wanted the correction to be completed in a short period of time. A smile design schedule was drawn up involving root canal treatment of the central incisors and placing posts in both the teeth. All ceramic crowns were then fabricated to establish a very satisfactory and pleasing esthetics.

Nanodentistry: A Paradigm Shift-from Fiction to Reality.

Nanodentistry is an emerging field with significant potential to yield new generation of technologically advanced clinical tools and devices for oral healthcare. Nanoscale topology and quantitative biomechanical or biophysical analysis of dental surfaces are of significant interest. In particular, using Atomic force microscopy techniques-diseases such as dental caries, tooth hypersensitivity, and oral cancer can be quantified based on morphological, biophysical and biochemical nanoscale properties of tooth surface itself and dental materials or oral fluids such as saliva. An outlook on future "nanodentistry" developments such as saliva exosomes based diagnostics, designing biocompatible, antimicrobial dental implants and personalized dental healthcare is presented. This article examines current applications of nanotechnology alongside proposed applications in the future and aims to demonstrate that, as well as a good deal of science fiction, there is some tangible science fact emerging from this novel multidisciplinary science.
