Summary

This study aims to compare the effectiveness of diode laser photobiomodulation combined with CPP-ACPF varnish versus CPP-ACPF varnish alone in reducing dentin hypersensitivity. Participants diagnosed with dentin hypersensitivity will receive either the combined treatment or varnish application alone. Pain levels will be evaluated using a standardized visual analog scale before and after treatment sessions. The results of this study may help determine whether adding diode laser therapy enhances the effectiveness of conventional varnish treatment in managing dentin hypersensitivity.

Detailed description

This study is a clinical trial designed to evaluate the effectiveness of two treatments for dentin hypersensitivity, which is the pain or discomfort felt when teeth are exposed to hot, cold, sweet, or touch. Participants who meet the study criteria will be randomly assigned to one of two groups: Group A: Treatment with a diode laser combined with CPP-ACPF varnish applied to the sensitive teeth. Group B: Treatment with CPP-ACPF varnish alone. Study Procedures: Screening and Enrollment: Participants will undergo a dental examination to confirm they have sensitive teeth. Medical history and consent will be collected. Baseline Assessment: Pain sensitivity will be measured using a simple pain scale to record how severe the sensitivity is before treatment. Treatment: The assigned treatment will be applied to the sensitive teeth. The laser procedure is painless and safe, and the varnish is a commonly used dental material. Follow-Up Visits: Participants will return for follow-up assessments immediately after treatment, after one month, after three months, and after six months. Pain sensitivity will be measured at each visit to track changes over time. Safety and Monitoring: The procedures are safe, and side effects are expected to be minimal. Any discomfort or unexpected reactions will be addressed promptly by the dental team. Participants can withdraw from the study at any time without affecting their standard dental care. Purpose of the Study: The goal is to determine whether combining diode laser treatment with CPP-ACPF varnish is more effective at reducing tooth sensitivity than using the varnish alone. The results may help dentists provide the best treatment options for patients with sensitive teeth in the future.
