The aim of this prospective study was to evaluate clinical and radiographic success of endodontically treated primary molars restored with resin composites (with different adhesives) or glass ionomers at 12 months follow-up. Materials and methods. 32 children 4-7 y. o. (mean 5.6±0.9) were included in clinical trial. 64 primary molars after endodontic treatment with Class II cavities was randomly divided in three groups according to restorative protocol: G1 – glass ionomer (n=20), G2 — resin composite with etch&rinse adhesive (n=28), G3 — with self-etch (n=16). Clinical evaluation was performed with modified USPHS criteria (marginal adaptation, marginal discoloration, retention, enamel loss) at baseline, 3, 6 and 12 months, x-ray control – after 1 year. Statistical analysis was performed with Fisher’s exact test (p<0,05). Result. After 12 months 60 teeth was examined (93.75%), 4 teeth in G1 was extracted due clinical and radiographic failures (internal resorption, pathological root resorption, furcal radiolucency). At 12 months marks “A” for marginal adaptation was 42,11% (G1), 85,71% (G2), 68,75% (G3); for marginal discoloration – 26,32%, 78,57%, 62,50% respectively. Absents or partial loss of glass ionomer was recorded in 25%. There was no significant differences during clinical examination between baseline and 12–month follow-up in resin composite groups for all criteria. After 12 months RC had better clinical condition then GI restorations according USPHS criteria (p>0.05). Radiographic failures was recorded in 3 teeth in G1 and in 1 case in G3 (periapical or furcal radiolucency, internal root resorption). Radiographic failures in glass ionomer group (G1) was always associated with defective coronal restoration. Radiological success for was 85,0% (G1), 100% (G2), 93,75% (G3) (p>0.05). Success rate of endodontic treatment and postendodontic restoration was 96,4% for resin composite with etch&rinse adhesive, 81,25% for RC with self-etch adhesive; 65,0% for GIC (p<0.05). Conclusion. Success rate of Class II restorations in primary molars after endodontic treatment with resin composites was higher than with glass ionomer. High rate of clinical and radiographic failures in glass ionomer group can be associated with coronal microleakage. Resin composites with etch&rinse adhesive can be suitable alternative for primary molars restoration after endodontic treatment with Class II cavities.
