Laser before filling may save more tooth in deep cavities
NCT ID NCT07358442
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether using a diode laser before placing a special filling material (Biodentine) helps preserve more healthy tooth and reduces staining compared to using Biodentine alone. 48 adults with deep cavities in permanent back teeth are being treated and followed with X-rays and photos. The goal is to see which method keeps more tooth structure and causes less discoloration.

Inclusion Criteria: 1. Patients aged \[ 18-45 years\] requiring treatment for a single deep carious lesion and willing to provide informed consent and comply with follow-up appointments. Candidates with good general health. 2. tooth-related criteria included reversible pulpitis or asymptomatic restorable vital permanent posterior molar. (based on clinical and radiographic examination, pulp vitality tests). 3. Radiographic evidence of deep caries approaching the pulp (e.g., inner half of dentin). 4. No signs of irreversible pulpitis or periapical pathology. Exclusion Criteria: 1. Patients undergoing orthodontic treatment or with significant periodontal disease affecting the study tooth or who cannot tolerate CBCT scanning. 2. patients who are medically compromised (systemic diseases affecting bone metabolism or healing (e.g., uncontrolled diabetes)). 3. pregnant ladies, patients with allergy to any component of Biodentine or other materials used, and patients who are not cooperative. 4. Tooth-related criteria involved teeth that have irreversible pulpitis or necrotic pulp (based on symptoms and vitality tests; spontaneous pain, or sustained pain after vitality tests (electrical or cold tests), teeth with pain on percussion ). 5. Teeth with periapical radiolucency and have been already restored before (previous endodontic treatment) 6. Extensive tooth destruction requiring full coronal coverage.
