Investigate the impact of antimicrobial photodynamic therapy (aPDT) using different photosensitizers (PSs) such as indocyanine green (IG), curcumin (CC), and methylene blue (MB), with or without intracanal application of calcium hydroxide (CH), on the push-out bond strength of glass-fiber posts (GFPs) to intraradicular dentin, the chemical composition of the root substrate, and the sealing of the adhesive interface across different thirds of intraradicular dentin. A total of 112 bovine teeth underwent biomechanical preparation and were divided into eight experimental groups (n = 14 each): Negative control with deionized water; positive control with deionized water + CH; IG group with indocyanine green and infrared laser; IG + CH group; CC group with curcumin and blue LED; CC + CH group; MB group with methylene blue and red laser; and MB + CH group. The push-out bond strength was measured using a universal testing machine (n = 8), and scanning electron microscopy characterized the fracture patterns.

Aim: The objective of the present study is to assess and compare the effectiveness of two different anesthetic agents, namely, 4% articaine and 2% lignocaine, in the extraction of primary molar teeth in children.

Materials And Methods: The study included 25 children requiring bilateral extractions of primary molar, with extraction performed on one side with 4% articaine and the contralateral side extraction with 2% lignocaine at two separate appointments. The anesthetic efficacy was evaluated objectively by assessing pain and the child's behavior at baseline, during injection and during extraction using the sound, eye, and motor (SEM) scale objectively, and subjectively using the faces pain rating scale (FPS).
