120 extracted human permanent maxillary first and second premolar teeth were included. All the teeth were then sectioned mesio-distally from the middle-third of crown using a high speed diamond disc to obtain dentin discs with 2mm thickness and any remaining enamel, surface irregularities were eliminated using 1200 fine grit silicon carbide polishing paper to create dentin discs with smooth, uniform surfaces. By using a double-sided tape, each dentin disc of all teeth were fixed on microscopic slides, with polished sides of dentin discs facing up. All the specimens were then randomly divided into 06 groups with 20 specimens per group. Group A; Low output Diode laser; 1W power, Group B; Remin Pro, Group C; CPP-ACP (GC Tooth mousse), Group D; NonFluoridated-Bioactive Glass (Shy-NM) and Group E; Fluoridated-Bioactive Glass (Elsenz) were used as desensitizing agents. A pea sized amount of desensitizing agent/paste as per the respective groups was placed on each of the dentin disc (Group F; Control group: 4ml Distilled water was used as desensitizing agent per specimen). By using Oral B Extra soft bristle toothbrush, each dentin disc was brushed in circular motion with light pressure twice a day at an interval of 12 hours for 2 minutes each for 14 days.
