    There has been an increase in the level of self-consciousness among individuals with regard to aesthetics. This has resulted in an increased demand for orthodontic treatment in recent years. There are several types of orthodontic treatment depending on the type of malocclusion. Each person may opt for a different appliance system to bring about orthodontic correction based on their preferences and esthetic needs. Hence this study was done to assess the patient’s preference for the use of orthodontic appliances. Aim: This study aims in analysing the preference of the patient to the different orthodontic appliance systems. Materials and method: This study included an examination of patients visiting our institution. The clinical data of patients aged 10 years to 50years was collected from the digital archives of our institution. Data like the preference for undergoing orthodontic treatment, the type of orthodontic appliance system that they are willing to undergo was then computed in excel format. The data was then processed and transferred to SPSS software where statistical analysis was done. Results: In the current study, about 53% of the patients preferred to undergo orthodontic treatment. 20.3% of the patients preferred fixed metallic appliances, 22.2% preferred fixed ceramic appliances, 9% preferred removable appliances, 16.6% preferred self-ligating appliances, 19% preferred lingual appliances and 23.8% preferred clear aligners.

    Materials that are taken from plants or animals and used for replacing and repairing are known as natural bioactive materials. These materials may interfere with the formation of a bond between the material used on the teeth and tissue. Bioactive materials with unique properties are on increased demand in all fields, for long term usage. In place of dental materials also, bioactive dental filling materials are now widely used. Bioactive dental filling materials hold a lot of advantages. Bioactive materials mimic materials such as bioactive dentin, bioactive aggregate, bioactive calcium hydroxide, bioactive glass, bioactive polymers, bioactive metals, bioactive mineral trioxide, aggregate, bioactive ceramics and so on. All bioactive materials do have their own advantages and some disadvantages on the teeth structure. These materials do have some challenges like some materials are ideal for certain patients and vary depending on the restorative needs of the patients, as options and opinions vary with patients. The need for these bioactive materials is mainly because of its demand and reducing the effects of secondary decay once it is replaced or done in the patients. These bioactive materials have more advancements and will change the future dentistry with its emerging technology. This article summarises the concept of bioactivity and compares the various available bioactive materials that are quintessential in every field and showcases the advancements in this topic of dental materials.

    Assessment of various risk habits among oral cancer patients18-22en [267.04 kB - PDF]EPA-02286-00095-0040

    Oral cancer is a major public health problem in the Indian subcontinent, where it ranks among the top three types of cancer in the country. Oral cancer is defined as the cancer of lips, mouth and tongue.The difference in incidence and pattern of oral cancer can be due to an overall effect of ageing of population as well as some regional differences in the prevalence of specific risk factor.Therefore the aim of the present study was to assess oral cancer incidence in patients based on forms of habits. This study was conducted in the Oral Cancer Department , Saveetha Dental College, Chennai. The study involved 50 patients who were clinically diagnosed with oral cancer. The various forms of habits observed were Guthka,Pan chewing ,Smoking. Pearson chi square test was done to statistically analyze the data and to identify any significant level of association. The most predominant form of habit was observed to be Pan chewing(n=11;22%) Out of the total 50 patients involved in the study it was observed that it was most predominant in the males(78%) with Pan chewing being the most predominant habit(n=10;25.6%) More number of oral cancer with various forms of habits were observed in above 50 years of age group(n=29;58%) Within the limitations of our study it was observed that oral cancer incidence in patients based on forms of habits was observed in above 50 years of age with a high predominance in the males and Pan chewing being the most common form of habit. Further studies with a larger sample size are required to compare the efficacy of oral cancer based on various forms of habits.

    Denture stomatitis is a common oral condition of multifactorial etiology. Factors such as age,gender,oral and denture hygiene may play a role in predisposition to denture stomatitis. The aim of this study was to evaluate these factors and understand the various modalities of treatment for effective management of denture stomatitis with respect to the South Indian population.Case sheets of around 26,000 patients were reviewed from March 2019 to June 2020 out of which a sample size of 56 patients were included. To eliminate bias all patients affected by the disease, who had completed treatment were included in the study. Epidemiological data of the patient along with their ongoing treatment was collected and tabulated in MS Excel sheet. The data was then analysed using IBM SPSS software version 23.The prevalence of denture stomatitis in females was 57.1% while in males was 42.9%. Age group of 51-60 years and 61-70 years was found to be equally and most commonly affected. Palate was found to be most commonly affected. The most common treatment modality used was pharmacotherapy using antifungal drugs.The increasing prevalence of denture stomatitis amongst the older population is a matter of great concern. The present study shows the prevalence of denture stomatitis in females especially in the old age population. Thus it is important to increase awareness amongst the patients regarding the condition and effective maintenance of oral and denture hygiene and to increase awareness amongst the dentists regarding the various treatment modalities to effectively prevent and clinically manage such conditions.
