Recruitment & Eligibility

• Status: COMPLETED
• Sex: All
• Target Recruitment: 36

Inclusion Criteria

• Active carious lesion in deep dentin of molars.
• Absence of cavitated lesions at the buccal or lingual surfaces as determined by clinical and radiographic examination.
• Absence of clinical diagnosis of pulp exposure, fistula, swelling of periodontal tissues, and abnormal tooth mobility;
• Absence of clinical symptoms of irreversible pulpitis, such as spontaneous pain or sensitivity to pressure;
• The extension of the carious lesion should be such that complete caries removal would risk pulp exposure, as determined by clinical and radiographic assessment;
• Absence of radiolucencies at the interradicular or periapical regions, or thickening of the periodontal spaces, that would indicate the presence of irreversible pulp pathologies or necrosis;
• Absence of internal or external root resorption.
• Co-operative patients approving the trial.

Exclusion Criteria

• Patients with systemic medical conditions
• pregnant females
• Teeth with spontaneous pain or sensitivity to percussion.
• Teeth with periodontal lesions, internal or external root resorption, mobility of tooth, sinus opening, or abscessed tooth.
• Radiographic examination revealed, interrupted or broken lamina dura, widened periodontal ligament space, periapical radiolucency.

Arm && Interventions

Group	Intervention	Description
Bioactive Glass	Bioactive Glass	18 teeth were capped indirectly with dental adhesive containing bioactive glass applied according to the manufacturer's instructions and cured for 20 seconds and then resin composite restoration containing bioactive glass applied by golden plated composite applicator in increments 2 mm each and cured for 40 seconds for each increment.
Light cured calcium hydroxide	Light cured calcium hydroxide	18 teeth were capped indirectly with light cured calcium hydroxide (control group) applied according to the manufacturer's instructions by calcium hydroxide applicator and light cured for 20 seconds then resin composite restoration was applied by golden plated composite applicator in increments 2 mm each and cured for 40 seconds for each increment.
