Past few decades have seen a significant increase in the prevalence of dental caries at a global scale. To reduce the pervasiveness of cariogenic microflora, various efforts have been undertaken. However, completely eradicating caries-associated microorganisms has been futile.1 Endogenous bacteria, such as Lactobacillus species, Streptococcus mutans, and Streptococcus sobrinus persisting in biofilms ferment carbohydrate and produce weak organic acids as by-products. This, in turn, results in a drop in the local pH well below the critical level, resulting in demineralization of tooth.2.

The most common fungal infection among human population is candidiasis, the etiology of which is mostly Candida albicans. As a result of a disrupted balance of the normal flora or a compromised immune system, Candida species can become pathogenic. Various in vitro surveys have shown that glucose intake is a promoter of C. albicans growth, whereas in vivo studies have found that xylitol can decrease the risk of candidiasis and angular cheilitis. Hence, we aimed to evaluate for the first time the inhibitory effects of xylitol on C. albicans by assessing its minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC).

Root caries is a common, debilitating condition particularly in the elderly population, which can lead to tooth loss. Evidence shows that green tea has cariostatic effects. Considering the gap of information on green tea varnish, this study aimed to assess the efficacy of green tea varnish in the prevention of root caries.

Both periodontitis and type II diabetes mellitus (T2DM) are common diseases with a multifactorial etiology and have influence of cytokines in their pathogenesis and thus may also influence each other. In recent times, more attention has been given to understanding the influences of these inflammatory cytokines which are a main part of oral chronic inflammation on systemic health of the individuals. Therefore, the aim of this study was to evaluate the plasma cytokine levels, specifically tumor necrosis factor-a (TNF-a), interleukin (IL)-6, and IL-4, in chronic periodontitis patients and T2DM patients, so as to investigate the influence of chronic periodontitis in systemic inflammation associated with diabetes mellitus.

The aim of the study was to evaluate the proliferative index (PI) at their invasive front of oral cancer and their association with Bryne’s grades of oral squamous cell carcinoma (OSCC) and compare the PI with lymph node metastasis, site of involvement, and habits.

Edentulism is one of the debilitating states affecting a significant portion of the geriatric population. It is often considered as the ultimate marker for predicting the pressure and burden on oral health. Respiration is also a routine vital function running continuously through the human body and most commonly assessed by a spirometer. Hence, we planned the present study to assess the impact of complete dentures on the functioning of the respiratory system.
