ABSTRACT
BACKGROUND: Sclerosis of dentinal tubules may be a response to pathological or physiological insult in the crown & root. The mechanism by which apical translucency is produced is still uncertain. The increase in size of the apical zone of sclerotic dentin in human teeth has been used often in forensic science as a method of age estimation. However, only few studies have been done to compare percentage of translucency between vital and non-vital teeth. Conflicting concepts exist regarding the amount of translucent dentin in the vital & non vital teeth and correlation of this variation with age of the subject. AIMS: To investigate the amount and distribution of apical translucent dentin in group-matched vital and non-vital teeth. MATERIALS AND METHODS: Study was conducted on 70 extracted teeth, which were subjected for vitality test before extraction, and divided into two groups (vital & non-vital teeth) with a minimum of 35 teeth in each group. Ground sections of 150µ thickness were observed under Stereomicroscope and photographed. The distribution of area and length was measured on the images captured, using PROPLUS IMAGE ANALYSIS SOFTWARE version 4.1.0.0 software. RESULTS AND CONCLUSIONS: The present study revealed significant differences (p < 0.05) in apical translucency of dentin, when both vital and non-vital teeth types were compared. There was more apical translucency present in non-vital when compared with vital teeth at any given age. Key words: Apical translucency; vital teeth; non-vital teeth.

ABSTRACT
BACKGROUND: An upsurge of herbal products in various catalogues of fast moving consumer goods is evident. Dental creams or pastes which have numerous brands since years, have addition of many more herbal tooth pastes. Main claim of these herbal tooth pastes being effective reduction in cavities and plaque control. Proven fact is that proper brushing with a tooth brush and tooth paste brings down the caries incidence, and there is a substantial amount of contribution made by indispensable ingredient i.e, tooth pastes and their antibacterial component. AIM: To evaluate the antibacterial efficacy of various herbal tooth pastes available in the market and compare it with a conventional tooth paste with known antibacterial effect. MATERIALS & METHODS: The antibacterial efficacy of five herbal tooth pastes and two conventional tooth pastes with different ingredients was evaluated by the zone of inhibition created around the disc on the culture plates against streptococcus mutans and lactobacillus acidophilus. RESULTS: The herbal tooth pastes showed similar efficacy as that of the conventional tooth pastes. One herbal tooth paste with multiple herbal ingredients had greater zone of inhibition compared to the conventional tooth pastes and other herbal tooth pastes. CONCLUSION: Herbal tooth pastes have similar antibacterial effect as conventional tooth pastes. Tooth paste with multiple herbal ingredients is more efficient than the tooth pastes with fewer herbal ingredients in an anticariogenic property.
