Aim and Objectives:Successful root canal treatment involves the complete elimination of microorganism from the root canal and the three-dimensional obturation of the canal space. Enterococcus faecalis is the most commonly found bacteria in failed root canal. Chemical irrigation of canals along with biomechanical preparation helps in the elimination of microorganisms. The present study was aimed to evaluate the antimicrobial effect of herbal root canal irrigants (Morinda citrifolia, Azadirachta indica extract, Aloe vera) with sodium hypochlorite (NaOCl).Materials and Methods:The bacterial E. faecalis (ATCC) culture was grown overnight in brain heart infusion (BHI) broth and inoculated in Mueller–Hinton agar plates. Antibacterial inhibition was assessed using agar well diffusion method. All five study irrigants were added to respective wells in agar plates and incubated at 37°C for 24 h. Bacterial inhibition zone around each well was recorded. Results were tabulated and statistically analyzed using Statistical Package for the Social Sciences software for Windows, version 19.0. (IBM Corp., Armonk, NY.Results:Highest inhibitory zone against E. faecalis was seen in NaOCl fallowed by M. citrifolia and A. indica extract, and the least by A. vera extract.Conclusion:Tested herbal medicine (A. indica extract, M. citrifolia, A. vera) showed inhibitory zone against E. faecalis. Hence, these irrigants can be used as root canal irrigating solutions.

Probiotics are non-pathogenic living microorganisms used to prevent various medical conditions. They have been added in some food products because of their beneficial effect in health. They play a beneficial role in preventing common oral health problems such as dental caries, periodontal disease, fungal infections (candida) and halitosis.

Background:Internet is a useful tool to update the knowledge. The aim of the present study was to assess the current level of knowledge on the computer and internet among under graduate dental students.Materials and Methods:The study consists of self-administered close ended questionnaire survey. Questionnaires were distributed to undergraduate dental students. The study was conducted during July to September 2012.Results:In the selected samples, response rate was 100%. Most (94.4%) of the students had computer knowledge and 77.4% had their own computer and access at home. Nearly 40.8% of students use computer for general purpose, 28.5% for entertainment and 22.8% used for research purpose. Most of the students had internet knowledge (92.9%) and they used it independently (79.1%). Nearly 42.1% used internet occasionally whereas, 34.4% used regularly, 21.7% rarely and 1.8% don’t use respectively. Internet was preferred for getting information (48.8%) due to easy accessibility and recent updates. For dental purpose students used internet 2-3 times/week (45.3%). Most (95.3%) of the students responded to have computer based learning program in the curriculum.Conclusion:Computer knowledge was observed to be good among dental students.

Sialolithiasis is a condition characterized by the obstruction of a salivary gland or its excretory duct due to the formation of calcareous concretions, resulting in salivary ectasia and subsequent dilatation of the salivary gland. This disease is mostly seen in adults or young adults, and seldom develops in children with submandibular gland duct being the most common site. This case report describes a 19 year old patient presenting with pain and swelling in right side of floor of mouth. Sialolithiasis of right submandibular gland was diagnosed based on clinical and radiographic examination. The sialolith was removed under local anesthesia.
