The present study concluded that the new set protocol followed is significantly effective in reducing the microbial load in the water tubing, container and aerosol production. It is an effective measure for reducing the chances of cross infection in the dental surgery.
Probiotics are the living microorganisms that have been commonly used in the prevention of gastrointestinal disorders. In recent times, probiotic and prebiotics have been used to assess and develop a natural balance of the microbial flora in the respiratory tract and the oral cavity as an adjunct therapy. They are known to augment the existing microbial flora that is beneficial to the host. Prebiotics are nondigestible food ingredients that help in increasing populations of probiotic bacteria. Recent studies have shown that probiotics help in active reduction in gingivitis, dental caries, periodontitis, and halitosis by replacing the harmful oral species, by means of utilizing abundant health-associated oral microbial species. Additionally, the nitrate-reducing bacteria have shown promising effect in improving efficiency of probiotic strains to accentuate oral health benefits. Probiotics along with prebiotics effectively alter the host–microbial interface by achieving homeostasis in multifactorial diseases such as periodontal diseases and oral malodor. The aim of the review is to collate the existing information available on use of probiotics and prebiotics in oral cavity.
Kimura's disease (KD) is a rare chronic inflammatory disease of subcutaneous tissues and occurs predominantly in head and neck region. It is seen primarily in young Asian males. Typical clinical presentations are painless subcutaneous masses, regional lymph node enlargement, blood and tissue hypereosinophilia, and increased serum IgE levels. Here, we present a case of a 27-year-old female who presented with unilateral single nodular swelling in the right postauricular region. The diagnosis of KD was done based on characteristic histopathologic finding in conjunction with peripheral eosinophilia and increase in serum IgE levels.
Objective:Radiographic and histopathological evaluation of mechanical trauma on the development of maxillary molars in rat.Materials and Methods:Experimental study with 7-day-old five new born Wistar rats. Trauma induced on 7th postnatal day with #55 K file. Right first molar region of the maxilla was the experimental side, and the left side as control. Each animal was sacrificed for histopathological observation on 8th day (immediately next day of injury), 10th day (after 3 days of injury), 13th day (Enamel completion), 19th day (Emergence into oral cavity) and 42nd day when all the teeth came into functional occlusion.Results:On the 42nd day experimental side of the study, the 1st molar tooth had not erupted and the radiographs taken revealed conglomerate mass suggestive of complex odontome. Reduced tooth size, altered enamel and dentin formation, abscess formation and complex odontome like structure were observed histopathologically.Conclusion:The diversity of morphlogical and histopathological changes to intrusive force implies intricate mechanism involved in tooth development.
Cosmetic treatments have become an integral part of periodontal treatment. One of the commonly used esthetic periodontal procedures is coverage of denuded root surface. While considering the elimination of these defects two criteria should be considered, the esthetic aspects and the functional aspects. This case report has describes a two stage surgical technique using double pedicle flap with connective tissue graft followed by coronally advanced flap for the treatment of a severe localized gingival recession measuring 15 mm. The recession measurement at the end of 12 months was 1 mm. It showed a predictable result at the end of one year. The advantages of this technique are excellent colour matching, dual blood supply to graft and very predictable results. The promising result suggest that this technique can be used in severe gingival recession cases with minimum amount of keratinized tissue.
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.
