Comparative evaluation of antimicrobial efficacy of nanosilver solution, Azadirachta indica, sodium hypochlorite, and normal saline as root canal irrigants in primary teeth.

Background: Microorganisms are the main cause of pulpal and periapical diseases. Hence, the elimination of such potential microbes is achieved by endodontic treatment. Mechanical preparation is the main mechanism to reduce the bacterial load in canals which is enhanced by intracanal irrigants. Despite these procedures, some bacteria might persist within the canals. It is important to disinfect the pulp space and dentinal tubules thoroughly with an effective endodontic irrigant to prevent reinfection of a treated root canal. Aim: This study aimed to evaluate and compare the antimicrobial efficacy of nanosilver (NS) Solution, Azadirachta indica, sodium hypochlorite, and normal saline when used as irrigants in infected root canals of primary teeth. Settings and Design: The study was a prospective randomized control trial which was conducted as per the consort statement. Materials and Methods: Eighty pulpally involved primary teeth requiring endodontic treatment of children aged 5-12 years were selected for this study. The subjects were randomly allocated to 4 groups (3 irrigant and control groups) consisting of 20 children each where Group I = NS solution, Group II = A. indica, Group III = Sodium hypochlorite (2.5%), and Group IV = Control group. Microbiological samples were collected at the baseline (before irrigation) and postirrigation after biomechanical preparation using the selected irrigant. The samples were subjected to an anaerobic bacterial culture test. Microbial colonies were identified and expressed as colony forming units per milliliter. Statistical Analysis: Data were analyzed using one-way analysis of variance, Paired t-test, and Post hoc Bonferroni test. Results: NS solution showed the highest mean of 4.384 × 103 ± 1.019 followed by Sodium hypochlorite with a mean of 3.500 × 103 ± 1.193 and A. indica of 2.590 × 103 ± 0.778. Conclusion: Based on the results of this study, NS solution can be used as an alternative to other root canal irrigating solutions in primary teeth.

Antimicrobial effectiveness of Nano Silver Fluoride Varnish in reducing Streptococcus mutans in saliva and plaque biofilm when compared with Chlorhexidine and Sodium Fluoride Varnishes.

Background: This in vivo study was done to investigate the antimicrobial effectiveness of Nano Silver fluoride, Sodium fluoride and Chlorhexidine when used as a varnish on Streptococcus mutans (S.mutans) in saliva and plaque biofilm. Material and Methods: 120 caries free subjects, aged 8-10 years were randomly assigned to four different groups (n=30) - group I: Control, group II: Chlorhexidine varnish (CHX), group III: Sodium fluoride varnish (NaF), group IV: Nano Silver fluoride varnish (NSF). Varnish application was done once at baseline. Saliva and plaque samples were collected at baseline (T0), at the end of 1 month (T1) and 3 months (T3) to evaluate S.mutans levels by culture method, optical density and PCR. OHI-S Index was also recorded for clinical evaluation. Results: NSF, CHX and NaF were effective against S.mutans activity. The intragroup comparision of CFU/ml and OD/ml count showed a highly significant reduction from baseline to 3 months for all the 3 varnish groups (p=0.001). PCR result revealed that maximum reduction was seen in NSF and CHX followed by NaF group. Conclusions: NSF reduces S.mutans level in both saliva and plaque biofilm and it is more advantageous than CHX and NaF as it has dual properties of acting as an antibacterial as well as a remineralizing agent. Key words:Chlorhexidine, Nano Silver fluoride, Sodium fluoride, S. mutans, varnish.

Assessing Videoconferencing as a Method of Remote Consultation in Pediatric Dentistry.

Background: The oral health condition in rural areas remains compromised due to insufficient healthcare providers. Implementation of teledentistry through videoconferencing in these areas can improve this situation when trained personnel are able to carry out real-time consultations of the patients with a pediatric dentist. Aim: To observe the feasibility of using teledentistry for an oral examination, consultation, and education, and also to assess the participant's satisfaction regarding the use of teledentistry for a routine dental checkup. Materials and methods: An observational study was carried out with 150 children aged 6-10 years. About 30 primary health centers (PHC)/Anganwadi (AW) workers were trained to perform the oral examination with the intraoral camera (IOC). Four self-constructed and nonstructured questionnaires were prepared to understand the knowledge, awareness, and attitude of the participants toward pediatric dentistry and their acceptance of teledentistry. Results: A total of 83.3% of children were not scared and felt that the use of IOC was better. About 84% of the PHC/AW workers found teledentistry very convenient, easy to learn, and adapt. And around 92% thought that teledentistry is time-consuming. Conclusion: Teledentistry is a possible way to provide pediatric oral health consultation in rural areas. It can save time, stress, and money for people in need of dental treatment. How to cite this article: Agarwal N, Jabin Z, Waikhom N.
