Aim:The aim of the present study was to determine whether hair could be used as biomarker of fluoride exposure.Materials and Methods:The study was carried out on 30 people living in an endemically fluoridated area and a low fluoridated area. Samples of hair from the occipital were taken and subjected to fluoride analysis by a fluoride ion electrode.Results:Lower fluoride levels in water supplies correlated with lower levels of fluoride in hair and more over higher fluoride levels in water correlated with higher levels of fluoride in hair. A direct relationship was evident between fluoride levels in water supplies and concentration of fluoride in hair (P < 0.01).Conclusions:The results of the present study indicate hair can be used as an indicator of fluoride exposure.

Background: Photography often represents the best method to collect and preserve evidences. The attention towards the advanced photographic presentation in dentistry has increased significantly over the past several decades. Advancements in technology, computers, the internet, and communication systems have greatly affected and shaped modern society. Aims and objectives: The present study was conducted to assess the awareness of digital photography among randomly selected academicians, practioners and both academicians and practioners. Materials and Methods: 250 dentists were included in the study and each was given a set of questionnaires. All the answers were marked as positive and negative and the data were tabulated and statistically analyzed. Results: The mean and standard deviation of the positive and negative responses were 6.18 ± 1.33 and among the subjects; the practioners showed the highest positive response of 100%. Conclusion: Combining a passion for photography with a dedication to dentistry leads to successfully record patient cases so as to have a better proposition in teaching, motivation, treatment and follow up.
