Background: Garlic ( Allium Sativum ) is ubiquitous, small and commonly used spice for processing food. There are many types of garlic and differ in shape, size, color, taste, number of cloves per bulb and storability. Objectives: To determine and compare the antibacterial activity of soft neck and hard neck species of garlic against cariogenic bacteria ( Streptococcus mutans and Lactobacillus acidophilus) . Materials and Methods: The well diffusion method was used to evaluate the antibacterial activity of garlic against Streptococcus mutans and Lactobacillus acidophilus . After incubation in an appropriate culture medium, diameter of zone of inhibition was measured to assess the antibacterial efficacy of garlic extract. Chlorhexidine mouthwash (ICPA HEALTH PRODUCTS LTD.) was kept as control group. Results were statistically analyzed using Kruskal Wallis test and independent ’t’ test. Thus, zone of inhibition (in mm) was analyzed using mean of all the readings obtained and the level of significance at <0.05 was considered statistically significant at 5% of level of significance. Results: Maximum zone of inhibition was found with hard neck garlic extract (24mm) followed by soft neck garlic extract (18mm) and Chlorhexidine (17mm) against Streptococcus mutans and Lactobacillus acidophilus . Conclusion: Action of garlic against Streptococcus mutans and Lactobacillus acidophilus raises the possibility that it can be used for dental caries and other oral infections possibly.

Objectives:The objective of the study is to assess the prevalence of dental caries and periodontal health status among individuals suffering from thyroid dysfunction in Nashik. To compare the prevalence of thyroid dysfunction between males and females.Materials and Methods:The present study is cross-sectional in nature. The study group comprised of randomly selected 100 individuals diagnosed as suffering from thyroid dysfunction and fulfilling eligibility criteria, visiting endocrinology center in Nashik city. Type III clinical examination was used for the assessment of oral health status. Control group was selected from the neighborhood in general population who had matched with the eligibility criteria of the study group. Oral hygiene status was assessed by using the WHO pro forma, 2013. Collected data were compiled into MS-Excel and subjected to statistical analysis using appropriate statistical tests.Results:Severity of dental caries status and periodontal destruction was found more in study group as (P < 0.05). The prevalence of thyroid dysfunction, severity of dental caries status and periodontal destruction was seen more in females as compared to males.Conclusion:Thyroid dysfunction has an impact on general and oral health as well. It is necessary to identify it early so as to prevent further progression of disease and destruction of oral tissues. It is also necessary to modify treatment plan if the patient is diagnosed with thyroid dysfunction to prevent further complications.
