Pit and fissure sealant application updating the technique

And pit-and-fissure sealing has been considered as the standard procedure to prevent caries [7].

Pit-and-fissure sealing in preference to no sealant or fluoride varnish is recommended by the recent evidence-based guidelines of the American Dental Association (ADA) and the American Academy of Pediatric Dentistry (AAPD) [8].

In the clinic, dentists frequently encounter the dilemma that an invasive ‘‘biopsy’’ is carried out in order to evaluate the extent of caries and restore the teeth [6].

Therefore, young patients with caries activity are clinically advised to adopt preventive pit-and-fissure sealing.

In addition, different sealants showed no significant effect on the SBS and microleakage performance.

Lately, the report of Zhuge has shown that the depth of resin tags inside the dentinal tube can be improved by the subpressure technique [17].These molars were stored in a normal saline solution before use [19].After the roots of the teeth were cut off, the crowns were embedded in acrylic resin and the buccal enamel surfaces were exposed.In order to obtain flat enamel surfaces with diameters of at least 3 mm, the buccal enamel surfaces were grounded with water-cooled silicon carbide sandpaper (400-, 800-, and 1200-grade paper).88 specimens with the original flat enamel surface were assigned to group F and were used for interface observation and the shear bond strength (SBS) test; 40 specimens with the original flat enamel surface and 40 specimens with round cavities of 2 mm in diameter and 1 mm in depth prepared with a dental handpiece were assigned to group A and group B, respectively.

The enamel of 168 specimens was grounded to a flat surface. Sealants were applied to enamel surface (88 specimens, group F) either subjected or not to subpressure.
