Radiographical impact of photobiomodulation therapy on bone regeneration in clinical studies: a systematic review.

Bone regeneration is a complex process influenced by inflammation and pathological conditions. Efforts to enhance this process include chemical and physical interventions, with PBMT therapy showing promise in improving bone regeneration. Despite conflicting findings in existing literature, this review aims to synthesize clinical evidence on using therapy (PBMT) in bone regeneration and explore its potential clinical applications.

Involvement of dopaminergic system in the dentate gyrus of the hippocampus in modulating the orofacial pain-related behaviors in the rats.

Chemical stimulation of the lateral hypothalamus (LH) induces analgesia by forming neural circuitries with multiple brain regions. The involvement of hippocampal dopaminergic receptors in the LH stimulation-induced antinociception in specific pain models in animals has been documented. However, because the neural circuitries involved in the mediation of orofacial pain are not the same as those that mediate the other types of pain, the present study aims to detect the role of dopamine receptors within the dentate gyrus (DG) in the antinociceptive responses induced by LH stimulation in an animal model of orofacial pain.

Effect of Different Surface Treatments and Pressure Conditions on Shear Bond Strength of Zirconia Ceramic to Composite Resin.

The aim of this study was to assess the shear bond strength (SBS) of zirconia ceramic to composite resin with various surface treatments following pressure changes. Totally, 135 zirconia blocks were prepared by computer-aided design/computer-aided manufacturing technology. The samples were divided into 9 groups (n=15).
