title: Evaluation of sealing ability two self-etching adhesive systems and a glass ionomer lining LC under composite restoration in primary tooth: An in vitro study.
abstract: OBJECTIVE
  To evaluate the sealing ability of two self-etching adhesive systems and glass ionomer cement (GIC) lining Light cure (LC) under composite restorations in primary teeth.
  
  
  METHODS
  Class V cavities are prepared on the cervical third of the facial and lingual surfaces of primary molars. The specimens are then assigned into four experimental groups. The restored primary molars are stored in distilled water and subjected to thermocycling. Each section was examined using a stereomicroscope to assess dye penetration at the margin of the restoration and evaluated via pictures.
  
  
  METHODS
  The degree of microleakage was analyzed using Kruskal-Wallis test and the intergroup significance by multiple comparison analysis.
  
  
  RESULTS
  The mean rank of the groups are Group I (Adper Prompt™ + Z-100) 19.44, Group II (UniFil BOND + Solare) 5.38, Group III (GIC lining LC + Z-100) 20.06, and Group IV (GIC lining LC + Solare) 21.13 with the P < 0.001.
  
  
  CONCLUSIONS
  Composite resin restorations bonded with two-step self-etching adhesive system (UniFil Bond) exhibited lesser microleakage than one-step self-etching adhesive system (Adperprompt™) in primary teeth.
