Context:The success of atraumatic restorative treatment (ART) technique depends on the restorative material; hence, clinical studies with various materials are necessary.Aim:The aim of the present study was to clinically evaluate and compare the nanoionomer and high-viscosity glass ionomer using United States Public Health Services (USPHS) Modified Cvar/Ryge Criteria with ART approach.Materials and Methods:Two primary molars in 50 healthy children aged between 5 and 8 years were selected for the study. The teeth were treated with ART and divided into two groups. The group 1 teeth were restored with nanoionomer (Ketac Nano 100 3M ESPE) and group 2 with high-viscosity glass ionomer cement (HVGIC), (Fuji IX GC). Each restoration was evaluated using the USPHS Modified Cvar/Ryge Criteria at baseline and 6 months’ and 12 months’ time interval.Statistical analysis used:Chi-squared (χ2) test.Results:Nanoionomer was significantly better than HVGIC with respect to color match at baseline, 6 months, and 12 months (P<0.001). Nanoionomers were also significantly better than HVGIC in case of cavosurface marginal discoloration and marginal adaptation (P<0.001) at 6 months and 12 months. There was no significant difference between the two materials with respect to secondary caries at 6 months (P>0.05), but at 12 months, nanoionomer was statistically better than HVGIC (P<0.05). There was no statistical significant difference with respect to anatomical form and postoperative sensitivity (P>0.05).Conclusion:The results indicate that nanoionomer can be a successful alternative restorative material for use with ART technique.
Background: Oral diseases such as dental caries, gingivitis, and periodontitis are common among population. The present study was conducted to assess dental caries status and oral hygiene practice among school children. Materials and Methods: This school-based study was conducted on 520 children of age group of 12–14 years of both genders. Location, education, and employment status of parents, use of toothbrush, frequency of brushing, dental floss, total number of meals in a day, number of snacks between meals and sugar consumption, and decayed, missing, filled teeth were recorded. Results: There were 266 males and 254 females. Age group 12 years had 80 males and 90 females, 13 years had 70 males and 60 females, and 14 years had 116 males and 104 females. Ninety-six males and 110 females were from urban and 170 males and 144 females were from rural. The mean plaque score in 12-year male children was 0.61 ± 0.32, in 13-year children was 0.68 ± 0.45, and in 14 years was 0.74 ± 0.48. In males, the mean plaque score was 0.70 ± 0.38 and in females was 0.66 ± 0.42. In children from urban area, the mean plaque score was 0.62 ± 0.34 and from rural area was 0.74 ± 0.40. Four hundred and eighteen children were using toothpaste and they had plaque score of 0.76 and 102 children were using floss and they had plaque score of 0.89. Three hundred and twenty children were brushing once, 90 twice, and 110 irregular and there mean plaque score was 0.70, 0.61, and 0.76, respectively. The difference was significant ( P < 0.05). Conclusion: Authors found that oral health status of children consuming high sugar, more snacks per day, and brushing occasionally was poor.
Background. Coronavirus disease 2019 (COVID-19) is a global pandemic with more than 53,973 people affected in West Bengal state of India. Objectives. The aim of present study was to assess the Knowledge, Attitudes and Practices (KAP) of dental practitioners in Kolkata city, West Bengal, India regarding COVID-2019 pandemic. Materials and method. Online questionnaire was distributed among dentists across West Bengal city, using a combination of convenience and snowball sampling. The questionnaire had 17 questions: (1) Section A was ‘General section’ which comprised of socio-demographic and professional details of the subjects; and (2) Section B comprised of 14 questions depicting knowledge, awareness attitude and practice regarding COVID-19. The data collected was subjected to statistical analysis with level of significance at p=0.05. The descriptive statistical analysis was done to compute frequency and percentages. Intergroup comparison was determined by Chi-square statistical analysis to determine the level of significance for responses of each question. Results. Around 70.4% undergraduates participated in the study. Only 4.3% showed accurate knowledge with respect to the incubation period of coronavirus. Coughing and sneezing was considered to be the most common mode of transmission. 98.9% of dentists considered fever to be the characteristic symptom of the disease. Hand washing and alcohol rubs was advocated by 99.5% of the dentist. Emergency procedures were considered necessary by 90.8% dentists. 75.1% of dentists agree that their practice has been affected by the pandemic. Conclusion. A constant update regarding COVID-19 should be made available to dental health care professionals through webinars, seminars, discussions and articles. Dentists should keep themselves updated and help to fight against this pandemic.
Aim: To find and compare the qualitative and quantitative change in color and surface texture of feldspathic ceramic, pressable ceramic and ceramic used in computer-aided design/computer-aided manufacturing CAD/CAM after different surface treatments namely glazing, abrading and polishing. To compare the effectiveness of pearl finish polishing paste and Soflex polishing system used in the study. Setting and Design: In-vitro , comparative study. Materials and Methods: Disc-shaped feldsapathic, pressable, CAD/CAM ceramic specimens were fabricated. Surface roughness and color parameters Δ L*, Δa*, and Δ b* were measured before glazing, after glazing, after abrasion with 02 diamond bur and after polishing with two different polishing systems. Surface roughness was measured qualitatively using scanning electron microscopy and quantitatively using an optical profilometer. The value of color parameters was obtained using a colorimeter. Data were statistically analyzed with ANOVA. Statistical Analysis Used: SPSS software 20.0 version (IBM, New York, United states of America). Results: Unglazed feldspathic, pressable and CAD/CAM porcelain specimens showed a mean surface roughness value of 2.73 ± 0.38, 3.54 ± 1.42, and 3 ± 1.74 specimens. After glazing and polishing, the surface roughness values decreased. After abrasion, surface roughness values increased. Polishing did not alter the color along the red green axis and yellow blue axis. Conclusions: Abraded specimens of feldspathic, pressable and CAD/CAM after polishing using pearl finish polishing paste and Soflex disc became smoother than glazed specimens. When pearl finish polishing paste and Soflex discs were compared for their effectiveness the former appeared to be more superior but not to a significant level. Mechanically altering feldspathic, pressable, and porcelain used in CAD/CAM technology does not cause any change in shade.
