RESUMEN

BACKGROUND: The prevalence of oral disease during pregnancy affects the health of the fetus and mother. The interdisciplinary protocol between general dentists (GDs), gynecologists, and general medical practitioners (GMPs) is proved to reduce the incidence of maternal and neonatal complications. AIM: The aim of the present survey is to assess the knowledge, awareness, and attitude of practicing gynecologists, GMPs, and GDs regarding the association of periodontitis and adverse pregnancy outcomes. MATERIALS AND METHODS: This cross-sectional study was conducted among 150 health-care professionals in Madurai. A well-structured pretested questionnaire consisted of 12 questions which were used to assess the awareness of association regarding maintaining oral health during pregnancy among GMPs, GDs, and gynecologists. The knowledge, awareness, and practice scores were calculated for the correct answers to the questions. A software program (SPSS 12) was used for statistical analysis. RESULTS: The mean age of participants was of 33.14 ± 1.5, 32.58 ± 2.80, and 37.7 ± 9.7, respectively. Majority of the participants agreed the importance of dental examination and maintaining oral health during pregnancy GMPs (96%), GDs (100%), and gynecologists (92%). About 92% of gynecologists and GMPs supported that providing dental treatment during pregnancy improved pregnancy outcomes. About 64%, 76%, and 68% of GMPs, GDs, and gynecologists, respectively, confirmed the association between periodontal disease and adverse pregnancy outcomes. CONCLUSION: In this study, knowledge and awareness of gynecologists and GMPs are appreciable; however, their attitude toward bringing the facts into clinical practice needs to be improved through integrated programs.

RESUMEN

OBJECTIVE: To evaluate and compare the topographical features of enamel surface, etched with different materials. STUDY DESIGN: 10 extracted human primary molars were randomly selected and cut and trimmed to 1 mm2. Each group comprised of 10 blocks and the enamel was treated as follows: Group I-35% H3PO4; Group II-5.25% NaOCl + 35% H3PO4 ;Group III-5.25% NaOCl; Group IV no treatment was carried out. All the samples were prepared for Scanning electron microscope analysis. The images were obtained and evaluated for the quality type I-II etching of the enamel surface using Auto-CAD 2011 software. STATISTICAL ANALYSIS USED: Wilcoxon Signed Ranks Test (p<0.001). RESULTS: The mean surface area of type I and II etching pattern values for Group- I was 39608.18 µm2 and Group- II was 45051.34 µm2. CONCLUSION: Deproteinization with 5.25% Sodium hypochlorite prior to acid etching could be used to increase the surface area of adhesion of composite material with the tooth surface.

RESUMEN

BACKGROUND AND AIM: It is inconclusive that periodontitis is an independent risk factor for adverse pregnancy outcomes. This study aims to investigate the association between maternal periodontitis and preterm and/or low birth weight babies. SETTINGS AND DESIGN: This was a prospective cross-sectional study. After prior informed consent, 3500 postpartum mothers were selected from various hospitals in Tamil Nadu and categorized into the following groups: group-1 - Normal term normal birth weight (n = 1100); Group-2 - Preterm normal birth weight (n = 400); Group-3 - preterm low birth weight (PTLBW) (n = 1000); and Group-4 - Normal term low birth weight (n = 1000). Periodontal examination was done, and risk factors were ascertained by means of questionnaire and medical records. STATISTICAL ANALYSIS: Comparison between case groups and control groups were done, odds ratio (OR) was calculated, and statistical significance were assessed by Chi-square tests. To control for the possible confounders, all variables with P < 0.05 were selected and entered into multivariate regression model, and OR and 95% confidence limits were again estimated. SPSS-15 software was used. RESULTS: Periodontitis was diagnosed in 54.8%, 52.3%, 53.8%, 59.4%, respectively. On comparison between the groups, none of periodontal parameters showed significant association except for the crude association observed in Group-4 for mild periodontitis (OR - 1.561; P = 0.000) and PTLBW. CONCLUSION: Periodontitis is not a significant independent risk factor, and obstetric factors contribute a major risk for preterm and/or low birth weight babies.

RESUMEN

AIM: To evaluate the prevalence of oral lesions status in human immunodeficiency virus (HIV) infected children of age 1 to 14 years in Anti Retro viral therapy (ART) centres in Tamil Nadu. MATERIALS AND METHODS: A of total 326 HIV infected children, age 1 to 14 years of which 174 male children and 152 female children were examined for Oral lesions in the Department of Pedodontics and Preventive Dentistry, Rajah Muthiah Dental College and Hospital, Annamalai University in association with the ART centers in Villupuram, Vellore and HIV Homes in Thiruvannamalai, Trichy and Salem in Tamil Nadu towns. STATISTICAL ANALYSIS: Statistical Package for Social Science for Windows (version 11 code: 3000135939012345). RESULT: Of the total 326 children, 201 (61.65%) had oral lesions. (68 [20.86%] with Oral Candidiasis [OC], 54 [16.56%] with Angular Cheilitis, 27 [8.28%] with Necrotizing Ulcerative Gingivitis [NUG], 25 [7.66%] with Necrotizing Ulcerative Periodontitis [NUP], 18 [5.53%] with Linear Gingival Erythema [LGE] and 9 [2.76%] with Apthous Ulcer.) Conclusion Among the oral lesions in HIV infected children, OC 20.86% was the predominant oral lesion followed by Angular Chelitis 16.56%, NUG 8.28%, NUP 7.66%, LGE5.53% and Apthous Ulcer 2.76%.
