Abstract
Aim: to assess and compare the possible post-operative pulpal symptoms (Spontaneous pain, pain on percussion, swelling, sinus or fistula), incidence of pulp exposure, child acceptance, chair time and radiographic success between both minimal and complete caries removal techniques.
Methodology: 70 children with deeply carious primary molars were divided into two groups: Study group: Minimal caries removal was performed in which only soft demineralized dentine along the lateral walls of the cavity was removed and no additional caries removal was performed followed
by SSC. Control group: Complete caries removal was done followed by SSC. Incidence of pulp exposure, chair time and child acceptance using 5 points Likert scale were recorded at the treatment visit and children were followed up clinically and radio-graphically for 9 months.
Results: MCR showed 100% total survival rate compared to 88% total survival rate for CCR. MCR showed other several clinical advantages over CCR; less pulp exposure, shorter chair time and higher child acceptability.
Conclusions: The results of this study confirm the clinical feasibility of MCR for the treatment of deep carious lesions. MCR requires less operative time than CCR, an extremely important factor in the treatment of children because it reduces chair time and patient discomfort. Moreover, MCR maintains pulp vitality making the treatment less complicated.
