Abstract
IntroductionAlthough selective caries tissue removal decreases the number and diversity of bacteria, stops the caries process, and reduces the risk of pulp exposure, the studies on the minimally removal of caries tissue are limited and further clinical research is necessary in this field.AimThis study aimed to evaluate through clinical and radiographic assessments the in vivo response of the dentin-pulp complex of human deciduous teeth after either partial or total caries removal (TCR).Materials and methodsA total of 49 deciduous molars of children aged between 5 and 9 years were carefully selected. The teeth were divided into two groups: Group I: Partial removal of caries; group II: Total removal of caries. Clinical and radiographic evaluations were performed during the period of 4 to 6 months after the procedure. The intraexam-iner reproducibility was determined by Kappa test. Fisher’s exact test was used to determine the statistical difference between groups.ResultsAll teeth showed clinical success during the 4- to 6-month evaluation period. The radiographic evaluation showed 94.2 and 89.6% of success rate in groups I and II respectively. Radiographic results did not show statistically significant differences between the studied groups (p > 0.05).ConclusionThe partial caries removal (PCR) showed satisfactory clinical and radiographic outcomes, suggesting that this minimally invasive approach might replace the TCR when correctly indicated.How to cite this article: Mello B, Stafuzza TC, Vitor L, Rios D, Silva T, Machado M, Oliveira TM.

Highlights
Selective caries tissue removal decreases the number and diversity of bacteria, stops the caries process, and reduces the risk of pulp exposure, the studies on the minimally removal of caries tissue are limited and further clinical research is necessary in this field
The partial caries removal (PCR) is based on the principle that careful dentin removal prevents further physical damage to the tooth and reducing the possibility of pulpal exposure.[2,3]
The PCR is based on the changing of the microenvironment of contaminated dentin underlying the restoration, maintaining tooth structure and pulp vitality.[5]
Summary
Selective caries tissue removal decreases the number and diversity of bacteria, stops the caries process, and reduces the risk of pulp exposure, the studies on the minimally removal of caries tissue are limited and further clinical research is necessary in this field. The PCR is based on the principle that careful dentin removal prevents further physical damage to the tooth and reducing the possibility of pulpal exposure.[2,3] The TCR of deep lesions may result in pulp exposure requiring more invasive treatments.[4] The PCR is based on the changing of the microenvironment of contaminated dentin underlying the restoration, maintaining tooth structure and pulp vitality.[5] The PCR maintains pulp vitality through the excavation to leathery or firm dentin at the pulpal wall of the cavity.[6] For this purpose, PCR involves the removal of infected dentin and preserves affected dentin, which, once sealed by the restorative material, is able to remineralize due to the absence of substrate.[7,8,9] It is not easy to determine exactly the amount of tissue to be removed,[6,10,11,12] so the subjective tactile sensation is the best guide.[6] the studies on the minimal removal of caries tissue are relatively limited and further research is necessary in this field. The literature lacks scientific evidences for defining a safe and adequate protocol to indicate PCR in primary teeth.[2]
