Abstract :

Aim of the study– This in vitro study was conducted with an aim to evaluate and compare the effect of three cavity disinfectants–Chlorhexidine gluconate–(Conspesis) ;Benzalkonium chloride –(Tubulicid Red );3% Sodium hypochlorite – ( ChlorCid–V) on sealing ability of dentine bonding system(3M ESPE). Materials and Methods–85 Class V cavity preparations were prepared on the buccal surfaces of extracted maxillary premolars with occlusal margins at the enamel and gingival margins in cementum and then they were divided into 5 groups –A, B, C, D & E. In the experimental groups A, B, C cavities were treated with combinations of one of the three cavity disinfectants with Adeper Easy One, self –etch dentine bonding agent and whereas groups D & E act as negative and positive control groups. After the cavity preparations were restored with resin composite Filtek Z 25O (3M ESPE), specimens were thermocycled, then the samples were subjected to dry leakage tests using Stereomicroscope. Results–After statistical analysis (Wilcoxon Signed Rank test, One way ANOVA test) it was concluded that no statistical significance between groups–A, B and D but there was statistically significant in groups C and E. Conclusion–2% Chlorhexidine gluconate based and 0.1% Benzalkonium chloride based can be used as cavity disinfectants with 3M ESPE bond, without affecting the sealing ability of dentine bonding system. Whereas 3%Sodium hypochlorite based is should not be used with dentin bonding system, because it alters its sealing ability
