Influence of Laser and Ozone Pretreatment on the Shear Bond Strength of Fissure Sealants: An In Vitro Comparative Study

Abstract

Aim: To evaluate the shear bond strength (SBS) of 3 fissure sealants used alone and with ozone and laser pretreatment. Materials and Methods: For the SBS test, the flattened enamel surfaces of 90 healthy third molars were randomly divided into nine groups ( n = 10 for each groups), based on different sealants (BeautiSealant, Fuji Triage, and Grandio Seal) and pretreatment conditions (no pretreatment, pretreatment with ozone, and pretreatment with neodymium-doped yttrium aluminum garnet [Nd:YAG laser]). Ozone was applied for 30 s in caries superficial mode, and Nd:YAG laser was applied for 60 s. After the pretreatment procedures, sealants were placed inside a mold on the enamel surface. SBS was measured with a universal testing machine. Data were analyzed using analysis of variance. Tukey’s multiple comparison tests were applied to determine the difference between the groups (α = 0.05). Results: The lowest SBS was observed in the Fuji triage group. Nd:YAG laser and ozone did not affect the SBS of BeautiSealant. However, significant differences were determined in the Fuji triage and Grandio Seal groups after pretreatment procedures ( P < .05). Conclusion: Ozone and laser can be employed to disinfect fissures before BeautiSealant application.

The Use of Artificial Intelligence in Dentistry Practices

“…Restorative dental treatment practice includes permanent and temporary filling materials, adhesive systems, prophylactic applications, high-speed rotating tools, and hand tools used in cavity preparation. 8 In their study, Zakeri et al 9 analyzed the sounds of high-speed rotating tools used in dentistry when in contact with teeth and restoration materials and studied the distinction of these sounds. In the study, amalgam and composite were used as restoration materials, and it was aimed to help dentists by preventing accidental loss of substance from dental tissue during the removal of restorations.…”
