Purpose:
To evaluate the clinical efficacy of incomplete caries removal in permanent molars with deep dental caries.
Methods:
One hundred and two permanent molars with deep dental caries were treated with partial caries removal combined with tight resin restoration. The patients were followed up for more than 6 months, the pulp retention rate and subjective feelings were evaluated.
