Inclusion criteria

Inclusion criteria: 1. Refer to the clinical diagnostic criteria for deep caries specified in the 5th edition of the textbook Endodontology and Operative Dentistry published by People's Medical Publishing House: caries lesions that have progressed to the deep layer of dentin. Clinical examination generally reveals relatively deep carious cavities, and patients present with obvious evoked pain in response to cold, heat, sour, sweet, and mechanical stimuli, which subsides immediately after the stimuli are removed. 2. The affected teeth are permanent teeth, excluding wisdom teeth and supernumerary teeth. The tooth structure is intact, with no periodontal disease or with stable periodontal treatment outcomes, and the probing depth is <= 3 mm. 3. The patients are aged 18–60 years, in good general health, free from underlying diseases that affect pulp repair such as diabetes and immune system diseases, and have provided informed consent and are able to cooperate with follow-up visits.

Exclusion criteria

Exclusion criteria: 1. The carious lesion has perforated the pulp or pulp necrosis is present (no response to pulp vitality testing). 2. The affected tooth has a history of previous root canal treatment, dental restoration, or trauma. 3. The affected tooth is complicated by periodontal disease or periapical lesions. 4. The patient is in pregnancy or lactation, or is allergic to the materials used in the experiment (resin, light-cured calcium silicate, calcium hydroxide). 5. Pulp exposure occurs due to incomplete caries removal. 6. The patient is unable to cooperate with follow-up visits.
