The main questions the study aims to answer are:\n\n* Do preoperative symptoms affect the outcome?\n* Does the depth of the carious lesion affect the outcome?\n\nOne hundred participants will be recruited. Patients who meet the eligibility criteria will be asked to give their informed consent to participate in the study. Partial carious tissue removal will be performed regardless of participation in the study because selective carious tissue removal is the standard treatment of choice for a vital tooth with a deep carious lesion according to the Finnish national treatment guidelines. Participants will be asked to fill in a questionnaire regarding symptoms 7 days post-treatment. The teeth will then be followed up for 12-24 months.\n\nThe null hypothesis is that there is no difference in the success between i) deep and extremely deep carious lesions and ii) initial and mild pulpitis.",[25,26,27],"Deep Caries","Pulpitis Reversible","Pulp Hyperemia",[29,30,31],"vital pulp therapy","deep carious lesion","selective carious tissue removal","RECRUITING","2026-04-17",{"date":35,"type":36},"2026-04-22","ACTUAL",{"date":38,"type":36},"2023-04-21",{"date":40,"type":21},"2027-12-31",{"name":42,"class":43},"University of Helsinki","OTHER"]
