Comparasion of two minimally invasive methods on the longevity of glass ionomer cement restorations: short-term results of a pilot study

Abstract

The purpose of this study was to evaluate the clinical performance of glass ionomer cement (GIC) restorations comparing two minimally invasive methods in permanent teeth after 12 months. Fifty pregnant women (second trimester of pregnancy), mean age 22 ± 5.30 years, were treated by two previously trained operators. The treatment approaches tested were: chemomechanical method (CarisolvTM; MediTeam) and atraumatic restorative treatment (ART). A split-mouth study design was used in which the two treatments were randomly placed in 50 matched pairs of permanent teeth. The chemomechanical method (CM) was the test group and the ART was the control group. The treatments were performed in Public Health Centers. The tested restorative material was a high-strength GIC (Ketac Molar; 3M/ESPE). The restorations were placed according to the ART guidelines. Two calibrated independent examiners evaluated the restorations in accordance with ART criteria. The interexaminer kappa was 0.97. Data were analyzed using 95% confidence interval on the binomial distribution and Fisher's exact test at 5% significance level. In a 12-month follow-up, 86% of the restorations were evaluated. In the test group (CM), 100% (CI=93.3-100%) of the restorations were considered successful. In the control group (ART) 97.6% (CI=87.4-99.9%) of the restorations were considered successful and 2.4% unsuccessful (marginal defect >0.5 mm). There was no statistically significant difference between the 12-mounth success rate for both groups (Fisher's exact test: P=0.49) and between the two operators (Fisher's exact test: P=1.00). Both minimally invasive methods, chemomechanical method and ART, showed a similar clinical performance after 12 months of follow up.

“…34 The filler wt% of the composites was based on information provided by the manufacturers, except that for Filtek Z350 and Grandio, which was determined elsewhere through thermogravimetric analysis. 24 According to Sabbagh and others, 35 these data discrepancies should be viewed with caution, as they might result from weighing the particles after the silane treatment. 24 According to Sabbagh and others, 35 these data discrepancies should be viewed with caution, as they might result from weighing the particles after the silane treatment.…”

Systematic Review and Meta-Analysis of Randomized Clinical Trials on Chemomechanical Caries Removal

“…However, the detailed randomization and teeth isolation methods were not clearly reported, which may have affected the follow-up results of the resin composite restorations. The trial by Barata and others 35 was the only clinical trial that clearly described the detailed randomization method. All the reviewed trials were at least two-arm clinical trials, except the study by Bussadori and others, 26 which was a one-arm trial.…”

“…6,8,9,29,34 Conversely, the other trials 11,12,24,30-32 used standardized scales (eg, FLACC, SEM, Visual Analogue and Verbal scale, Frankl scale, 33 and Wong Baker Faces Pain scale), increasing the reliability of their results due to their unbiased outcomes. The majority of trials 8,10-12, 24,25,27,29,31,34,35 obtained ethical approval from their respective institutes or at least signed informed consent by the child's parent or guardian. 6,9,28 However, four trials 7,30,32,41 did not clearly mention any ethical related issues, which may have affected the confidence toward their methodologies and results.…”

“…8,10, 25,26,29,34,35 The trial by Topaloglu-Ak and others 10 was the only one that described the long-term follow-up (6, 12, and 24 months), which was performed under standard illumination conditions (battery-powered headlight). Bergmann and others 29 and Peric and others 25 did not restore the treated cavities with the same restorative material (amalgam, glass ionomer, or resin composite were used), which may have impacted the follow-up results.…”

Experience of Supervised Internships, Focusing Attention on the Health of Pregnant Women

“…In this context, it is accepted internationally that the promotion of health care directed toward pregnant women fosters health for the entire family, by means of the acquisition of healthy habits that are multiplied among all family members [22][23][24][25][26][27][28][29][30].…”
