Knowledge, attitude, and practices of interdental aids among medical professionals in Davangere district, Karnataka

Objectives: The purpose of this study was to evaluate awareness regarding interdental aids in medical population. Materials and Methods: This study included 337 medical professionals living in Davangere district, Karnataka, India. A dental health questionnaire was distributed to all subjects consisting of 18questions. Results: Total 337 people with 187 females and 150 males who were of mean age 27.6±9.0 years participated in the study. The significant positive response (<0.05) in females as compared to males was observed for two items (4 and 7). Conclusions: The low positive response towards interdental aids should focus to conduct mass educative programs providing information regarding different interdental aids

Periodontal implications of argyrophilic nucleolar organizer region: A mini reviewPeriodontal implications of argyrophilic nucleolar organizer region: A mini review

The periodontal lesions with cellular proliferation can be assessed by various methods. One of the methods to determine the proliferative activity is silver-staining argyrophilic nucleolar organizer region (AgNOR) staining. AgNOR can be used as diagnostic and prognostic tool for many of periodontal lesions which are proliferative in nature and may be quantitative marker of incipient cellular alterations before the histologic hallmarks appear. Hence, this paper reviewed about the periodontal applications of AgNOR staining

Comparative assessment of fluorosed and nonfluorosed fibroblast attachment on fluorosed and nonfluorosed teeth after scaling and root planning and ethylenediaminetetraacetic acid root biomodification

Background and Objectives: Fluorosis causes mineralization changes in the tooth and can lead to morphological alterations of fibroblasts. To evaluate the effect of fluorosis on periodontal healing, the initial step while healing such as, fibroblast attachment onto the root surface requires to be evaluated on the fluorosed and nonfluorosed tooth using nonfluorosed as well as fluorosed fibroblasts originated from the subjects influenced by high-water fluoride. Hence, the objective of the current study was to study and compare the attachment of nonfluorosed and fluorosed fibroblasts on the fluorosed and nonfluorosed root fragments. Materials and Methods: A total of 112 fluorosed and nonfluorosed, periodontally healthy and diseased tooth roots were obtained and allotted to eight groups : f0 luorosed healthy (FH) and non-FH (NFH) controls, fluorosed diseased (FD) and non-FD (NFD) controls, fluorosed and nonfluorosed teeth treated with scaling and root planning (SRP) (FD SRP and NFD SRP) and similar groups treated with SRP and ethylenediaminetetraacetic acid (EDTA) (FD SRP + EDTA and NFD SRP + EDTA) burnishing treatment with 24% EDTA gel for 2 min. After the respective treatment half of the root fragments in each group were incubated in the human periodontal ligament fibroblast cells obtained and cultured from freshly extracted FH and NFH human premolar tooth root. The nonfluorosed fibroblasts are elongated, flat cells thus they show increased attachment to root the surface. Results: When comparison was carried out between the attachment of fluorosed and nonfluorosed fibroblasts on NFD groups treated with scaling and EDTA, significant results were obtained with increased attachment seen on the group incubated with nonfluorosed fibroblasts (P = 0.029). While on comparison between the attachment of fluorosed and nonfluorosed fibroblasts on NFH group, NFD group treated with SRP and NFD group, no significant results were obtained (P > 0.05). On comparison between the attachment of fluorosed and nonfluorosed fibroblasts on FD group treated with SRP, highly significant results were obtained with increased attachment seen in the group incubated with nonfluorosed fibroblasts (P = 0.001). While the comparison of attachment of fluorosed and nonfluorosed fibroblasts on FH group, FD group treated with SRP + EDTA and FD group revealed no significant results (P > 0.05). Interpretation and Conclusion: SRP proves yet to be a standard requirement for fibroblast attachment to occur both in fluorosed and nonfluorosed teeth. Although, there is no significant difference in attachment between SRP and SRP + EDTA among fluorosed teeth, EDTA does not seem to be a promising agent for root biomodification in fluorosed teeth in given concentration and time of treatment
