This clinical trial will evaluate the effectiveness of eggshell-derived calcium hydroxyapatite compared to calcium hydroxide as indirect pulp capping agent in permanent teeth. A total of 54 teeth from healthy individuals aged 18 to 40 years will be randomly allocated into two groups:
Group A (experimental) treated with eggshell-derived calcium hydroxyapatite. Group B (control) treated with calcium hydroxide.
After caries removal the assigned pulp capping agent will be applied, and the teeth will be restored. Clinical and radiographic evaluations will be performed at 1 and 3 months to assess pulp vitality, symptom-free status, and periapical health.
Teeth with symptoms of reversible pulpitis.
Teeth that show positive response on electric pulp testing (EPT).
Teeth with caries penetrating up to three-quarters (¾) of dentine without pulp involvement.
Healthy cooperative patients of both sexes between 18 to 40 years of age.
Necrosed Teeth with radiolucency in the periapical and furcation regions.
Tooth with internal and external root resorption.
Periodontally compromised tooth. (BPE score 3 and above)
Physically and mentally handicapped patients. (ASA score 3 and above)
