Evaluation of Salivary Components and Dental Plaque in Relation to Dental Caries Status in Type 1 Diabetes Mellitus.

Purpose: To evaluate the dental caries prevalence in Type 1 Diabetes Mellitus (T1DM) as compared to healthy children and, to assess the salivary components (flow rate, glucose, α-Amylase, Streptococcus mutans) and dental plaque in relation to their dental caries status. Methods: Dental caries were estimated by using the DMFS index and dental plaque by Sillness and Loe plaque index. The following methods were used to assess the salivary components; draining method to determine the flow rate; glucose oxidase peroxidase method for glucose; substrate method for α-Amylase, Mitis Salivarius Bacitracin agar was used to culture Streptococcus mutans. Results: Caries prevalence was significantly lower in T1DM. In the diabetic group, a significant positive correlation was found between DMFS value and plaque, DMFS value and salivary glucose, and also with DMFS value and salivary α-Amylase. A significant negative correlation was found between the DMFS value and the unstimulated salivary flow rate. The multivariate regression analysis demonstrated that decrease in the unstimulated salivary flow rate to be significantly associated with increasing DMFS values. Conclusion: The caries prevalence was found to be low in T1DM when compared to the healthy children, the cause for it being related to the low plaque scores. Low caries prevalence could also be due to the restriction of sucrose in their diet. Clinical significance: As clinicians, along with restoring the smiles of a child patient, we have to retrospectively analyze the factors involved in the causation of dental caries. Educating the parents and the child in regard to this will help prevent the occurrence of any new carious lesion. How to cite this article: Manjushree R, Anandakrishna L, Prasad KS K, et al.

Comparative efficacy of two poeciliid fish in indoor cement tanks against chikungunya vector Aedes aegypti in villages in Karnataka, India.

BACKGROUND: In 2006, severe outbreaks of Aedes aegypti-transmitted chikungunya occurred in villages in Karnataka, South India. We evaluated the effectiveness of combined information, education and communication (IEC) campaigns using two potential poeciliid larvivorous fish guppy (Poecilia reticulata) and mosquitofish (Gambusia affinis), in indoor cement tanks for Aedes larval control. METHODS: Trials were conducted in two villages (Domatmari and Srinivaspura) in Tumkur District from March to May 2006 for Poecilia and one village (Balmanda) in Kolar District from July to October 2006 for Gambusia. A survey on knowledge, attitude and practice (KAP) on chikungunya was initially conducted and IEC campaigns were performed before and after fish release in Domatmari (IEC alone, followed by IEC + Poecilia) and Balmanda (IEC + Gambusia). In Srinivaspura, IEC was not conducted. Larval surveys were conducted at the baseline followed by one-week and one-month post-intervention periods. The impact of fish on Aedes larvae and disease was assessed based on baseline and post-intervention observations. RESULTS: Only 18% of respondents knew of the role of mosquitoes in fever outbreaks, while almost all (n = 50 each) gained new knowledge from the IEC campaigns. In Domatmari, IEC alone was not effective (OR 0.54; p = 0.067). Indoor cement tanks were the most preferred Ae. aegypti breeding habitat (86.9%), and had a significant impact on Aedes breeding (Breteau Index) in all villages in the one-week period (p < 0.001). In the one-month period, the impact was most sustained in Domatmari (OR 1.58, p < 0.001) then Srinivaspura (OR 0.45, p = 0.063) and Balmanda (OR 0.51, p = 0.067). After fish introductions, chikungunya cases were reduced by 99.87% in Domatmari, 65.48% in Srinivaspura and 68.51% in Balmanda. CONCLUSIONS: Poecilia exhibited greater survival rates than Gambusia (86.04 vs.16.03%) in cement tanks. Neither IEC nor Poecilia alone was effective against Aedes (p > 0.05). We conclude that Poecilia + IEC is an effective intervention strategy. The operational cost was 0.50 (US$ 0.011, 1 US$= 47) per capita per application. Proper water storage practices, focused IEC with Poecilia introductions and vector sanitation involving the local administration and community, is suggested as the best strategy for Aedes control.

Application of cone-beam computed tomography in the management of dilacerated maxillary central incisor associated with radicular cyst and external root resorption - A case report.

The maxillary anterior region is the most common site for the occurrence of radicular cyst in permanent dentition, because of a high frequency of trauma in this region. As radicular cyst is categorized as an inflammatory cyst, endodontic treatment of the tooth associated with the cyst becomes a part of the treatment regimen. Management of radicular cyst becomes challenging when it involves tooth with complex root morphology. This report presents the diagnosis and successful management of a dilacerated maxillary central incisor associated with a radicular cyst and external root resorption. Cone-beam computed tomography was used to view the extent of the cyst and understand the aberrant root canal morphology of the dilacerated tooth. Root canal therapy was followed by cyst enucleation, apicoectomy, and placement of platelet-rich fibrin. At 1-year recall, appreciable healing as evidenced by a decrease in the size of the radiolucency on the radiographic examination was seen.
