ABSTRACT
Free radicals have been implicated in the etiology of large number of major diseases. They can adversely alter many crucial biological molecules leading to loss of form and function. Such undesirable changes in the body can lead to diseased conditions. Antioxidants are compounds which destroy the free radicals in the body, thereby preventing against harmful oxidation- reduction reactions. Antioxidants are critical for maintaining optimum health and wellbeing. The best sources are fruits and vegetables which provide a variety of antioxidants like Vitamins A, C, E & carotenoids. As in every medical field, the usage of antioxidants is becoming more frequent in dentistry also. It can help adjunct treating the progress of oral problems such as periodontitis or gingivitis or progression of potentially malignant disorders to malignancy. Thus, a greater consumption of fruits and vegetables should be encouraged as they are the natural sources of these chemopreventive antioxidant along with other protective factors packaged by nature. This review focuses on commonly used effective antioxidants in different oral and dental pathologies as a new generation adjunctive remedy.
ABSTRACT
Context: Prediction values based on a particular race cannot be considered as universal. It requires revision according to developing malocclusion and relative size of the tooth. Aim: To evaluate the applicability of Moyer’s mixed dentition analysis with derivation of regression equation for Hindu children of Bhopal city; Materials and methods: The mesio-distal width of permanent mandibular incisors, maxillary and mandibular canine and premolars were measured for 200 children of 12-16 years of age using digital vernier caliper; Statistical analysis: Student’s ‘t’ test was applied to compare the actual and predicted values and linear regression equations were derived for prediction of tooth size. The correlation between the sums of the canine, premolars in both arches and mandibular incisors was done by using coefficient of correlation (r). The Student’s unpaired t test was applied to compare the tooth dimensions between male and female;Results: Moyer’s prediction values was not an accurate method to estimate tooth dimensions in the present study sample. The mesio-distal crown dimensions in both the arches were larger in males compared to the females ;Conclusion: Statistically significant difference was present between predicted values of Moyer’s table and the values obtained in present study sample. So uses of newly devised regression equations are recommended for prediction of the combined mesiodistal width of canines and premolars in Hindu populations of Bhopal city.
