Comparative characteristics of restoration criteria according to Ryge when filling with various glass ionomer filling materials

Background:According to modern concepts, the marginal fit of restorations, the presence or absence of microleakage, are the main factors determining the longevity of restorations. Objective: Evaluation of the safety and effect of various filling glass ionomer cements on the marginal fit of fillings and the development of secondary caries. Materials and methods: 39 patients were enrolled in the study, aged 3 to 13 years (6.56 ± 2.7 years). The split-mouth technique was used. Glass ionomer cements Ketac Molar and Cemion were used as filling materials.The restorations were assessed after 6 and 12 months using the Ryge criteria. 79 restored teeth were examined, including 36 temporary teeth (45.6%) and 43 permanent teeth (54.4%). Statistical processing was performed using SPSS software (Armonk, NY: IBM Corp) version 19.0. Results: After 12 months of observation, the preservation of fillings was observed in 89.7% of cases when using Ketak molar and in 43.6% of cases when filling with Cemion. Marginal adaptation of fillings after six months showed that 83.3% of restorations of temporary and 90.5% of permanent molars Ketak were assessed Alpha, Cemion restorations were assessed Bravo in 44.4% of temporary teeth and 28.6% on permanent teeth, and 4.8% of permanent teeth received a Charlie rating. Recurrent caries with filling with Cemion after 12 months was detected in 55.6% of temporary teeth and 57.1% of cases on permanent teeth. When filling with Ketak molar on primary teeth, recurrent caries was observed in 27.8% of cases, on permanent teeth – 14.3%. Conclusion: “Ketac Molar (3M ESPE, Germany) display good clinical performance over a period of 12- months. It is preferable for pediatric dental care able to maintain its properties for a long time, which is important for the prevention of complications of the carious process in children.The use of GIC Ketak molar for restoration of carious defects of chewing teeth improves the quality of filling by 2.06 times compared to GIC Cemion, reduces the risk of complications, stabilizes the clinical condition and patient satisfaction with the restoration over 12 months of observation.Evaluation of the restoration of Bravo for caries and Charlie or Delta for marginal adaptation indicates the need for manipulation.
