Sažetak
Self-etching adhesives represent a new generation of dental adhesives that combine in the same time enamel-etching with adhesive infiltration. Main advantages of self etching adhesives for placing sealants in alternative to dassive procedure with HjPOj enamel etching are: no need for applying acid, and no rinsing. The aim of the study was to evaluate both the penetration and sealing ability of a sealant applied after enamel treatment with a self-etching adhesive. Forty-five teeth divided in three groups of fifteen teeth were sealed with Concise White Sealant (3M Dental Products, Batch 200102! 9, Exp.2003-11) after enamel surface treated as follows: Croup 7: occlusal surface etched with 37% phosphoric acid for 30 s, rinsed for 1 5 s and air-dried for 1 5 s. After drying the sealant was applied and polymerized for 20s. Group 2: The occlusal surface treated with self-etching adhesive Prompt-L-Pop (Espe Dental AC, Batch 103890, Exp.20O2-O5) for 20s and lightened for 10s (Optilux, Demetron Research Company) The sealant was then applied and lightened for 20s. Croup 3: The occlusal surface was treated with the self-etching adhesive Prompt-L-Pop for 20s and directly followed by sealant application, the two materials were then simultaneously lightened 20s All teeth were thermocycled between 5 and 55°CfOr 1800 cycles with dwelling time of 10s. Microleakage was tested using a AgNO* dye solution. The teeth were embedded in acrylic resin, sectioned (3-5 sections per sample), and photog rap hied under a stereo-microscope f 10X). Microleakage scores were recorded using method of Ovreboand Raadal. A statistical analysis was performed using non-parametric Kruskal-Walhs and Mann-Whitney tests. Results: The sealant penetration rate is in between of 87, 8-92, 1% whatever the batch with no statistical significant difference between groups. The statistical analysis has shown a significant difference in leakage between classic H, PO« pre-etch technique and the self-etching conditioning (p=O, 0O3). No significant difference in leakage was found between self-etching batches with or without polymerization (p-0, 12). It can be concluded that the "all in one" self-etching Prompt-L-Pop is not so efficient as the combination H--PO etching + sealant to achieve a good enamel marginal sealing. Grant ECF No 20011856.
