Objective: The aim of this study was to evaluate the bond strength of a resin composite fissure sealant to enamel which was pre-treated with different laser pulse modes and additional acid etching.
Materials And Methods: Forty-two healthy molars and premolars were collected for this study and randomly divided into 6 groups (n=7). Group 1: Quantum Square Pulse (QSP); Group 2: Medium-Short Pulse (MSP) mode; Group 3: Super Short Pulse (SSP) mode; Group 4: QSP + acid etching; Group 5: MSP + acid etching; Group 6: SSP + acid etching.
: In the literature, the influence of parents who suffer from dental anxiety and a previous unpleasant experience at the dentist are cited as the two most common causes of dental anxiety in children. The aim of this study is to investigate the relationship between socioeconomic factors and the development of dental anxiety in children aged 9 to 12 years. : A total of 131 children and their accompanying parents/guardians participated in the cross-sectional study.

Material And Methods: A total of 137 intraoral periapical radiographs of MCI in children aged 7 to 11 years were examined and then classified into 5 groups according to root development stages, which included 1/2 of root development (S1), 3/4 of root development (S2), more than 3/4 of root development (S3), complete development with wide-open apex (S4) and complete development with closed apex (S5). DWT was measured at three reference (horizontal) lines: at a distance of 1 mm from the apex (M), 4 mm from the apex (L) and at the cervical line (K).
