Introduction: With the enormous change in life style pattern of a common man through the past few decades, there has been proportional variation in the amount and frequency of consumption of drinks. An increased consumption of these drinks will concurrently increase enamel surface roughness by demineralization, resulting in hypersensitivity and elevated caries risk. Aim: The present study was designed to evaluate the erosive potential of commercially available drinks on tooth enamel and various tooth coloured restorative materials. Materials and Methods: Extracted human teeth were taken and divided into four groups i.e. tooth enamel, glass ionomer cement, composite and compomer. Four commercially available drinks were chosen these were Coca -Cola, Nimbooz, Frooti and Yakult. The pH of each drink was measured. Each group was immersed in various experimental drinks for a period of 14 days. The erosive potential of each drink was measured by calculating the change in average surface roughness of these groups after the immersion protocol in various drinks. The data analysis was done by One Way Anova, Post-Hoc Bonferroni, and paired t -test. Results: Group II-GIC showed highest values for mean of change in average surface roughness and the values were statistically significant (p<0.001) with tooth enamel, composite and compomer (p=0.002). Coca-cola showed the highest erosive potential and Yakult showed the lowest, there was no statistical significant difference between the results shown by Yakult and Frooti. Conclusion: Characteristics which may promote erosion of enamel and tooth coloured restorative materials were surface texture of the material and pH of the drinks. © 2016, Journal of Clinical and Diagnostic Research.

Adenomatoid odontogenic tumour is an uncommon, benign, hamartomatous lesion that commonly affects the anterior maxilla and has two radiographic variants, follicular and extrafollicular where the former is more common than the latter. Here, we report a case of 15-year-old female with midline swelling of the mandible. Radiographically, impacted right permanent mandibular canine was associated with the radiolucent lesion. Dentigerous cyst was given as provisional diagnosis. However, histologically the lesion represented the features of cystic variant of Adenomatoid odontogenic tumour.

Current Gene Therapy | Year: 2014

Epigenetics means gene expression alterations which occur due to the biochemical changes of the nucleotides modifying structure of DNA rather than the changes in the genetic code itself as in case of mutations. The epigenome, consisting of chromatin and its modifications, acts as a link between the inherited genome and the changes imposed by the environment. Over the past decade, there has been mounting evidence suggestive of associations between epigenetic modifications and various human conditions such as aging, and most common human diseases viz. cancer, cardiovascular diseases, diabetes, rheumatoid arthritis, HIV etc and the clearest evidence as the central mechanism for common multifactorial diseases, has been identified with the factors involved in the inflammatory response. Periodontal disease, basically an immune-inflammatory affliction, being a multifactorial complex disease, owing to its high prevalence, chronicity and wide ranging systemic effects, essentially calls for a better comprehension of the underlying disease mechanisms, so as to develop and decipher the novel methodologies to combat this disease. The current paper aims to visualize periodontal disease from an epigenetic perspective, featuring the contemporary evidence supported literature and tends to explore the possibilities to find some explanations for perio-systemic health links, individualized and improvised diagnostic tools for earlier detection and ways to halt the disease and help regeneration and reconstruction of the lost periodontal attachment apparatus with the biology based approaches. © 2014 Bentham Science Publishers.

Periodontal disease, is the most prevalent inflammatory affliction characterized by the loss of supporting structures of the teeth. Although bacteria are identified as prime agents initiating the disease, but major part of tissue destruction is driven by the host immune response to infecting agent and is responsible for the clinical presentation of the disease. Porphyromonas gingivalis (P. gingivalis) has been identified as main microbial factor for causation and progression of periodontal disease. Three emerging concepts of periodontal disease viz wide prevalence, polymicrobial nature and their role in perpetuation of systemic diseases bear critical significance on the development of novel therapeutic approaches to eradicate or alleviate the disease burden. Therefore, development of preventive approaches such as periodontal vaccine appears as an exciting modality which can prove as a significant adjunct to current periodontal therapies. The new generation diagnostics including microbial genome sequencing and bioinformatics analysis are available now to detect and analyze the whole genomic and proteomic data regarding almost all human pathogens for exploring these as novel drug targets for vaccine development. The current review, aims to provide an update of wide-ranging virulence factors of P. gingivalis as potential antigenic targets for periodontal vaccine development.

Ribbond is a biocompatible, esthetic material made from high-strength polyethylene fiber. Lenowoven polyethylene ribbon (Ribbond) has been used successfully for tooth splinting, replacement of missing teeth, reinforcement of provisional acrylic resin fixed partial dentures, and orthodontic retention. This article presents the application of this polyethylene ribbon - RIBBOND - for the treatment of nursing bottle caries. To conclude we suggest that this combined technique of polyethylene fibers and composite material could be a very efficient alternative procedure to conventional treatment plans in pedodontic practice, with excellent esthetics and functional results.
