Clinical and radiographic evaluation of adhesive pulp capping in primary molars following hemostasis with 1.25% sodium hypochlorite: 2-year results.
PURPOSE To evaluate , prospect ively , the clinical and radiological response of primary molars , pulp-capped with calcium hydroxide and different adhesive systems  after hemorrhage control with 1.25 % sodium hypochlorite ( NaOCl ) . METHODS 100 primary molar teeth were pulp-capped in 67 children who met inclusion criteria . Hemorrhage at the exposure site was controlled with 60 seconds application of 1.25 % NaOCl . Teeth were r and omly assigned into five groups ( n=20 each ) with respect to the material /technique used for capping : ( 1 ) calcium hydroxide cement ( Dycal ) ; ( 2 ) acetone-based total-etch adhesive ( Prime&Bond NT ) ; ( 3 ) a non-rinse conditioner ( NRC ) and Prime&Bond NT ; ( 4 ) total-etching with 36 % phosphoric acid followed by Prime&Bond NT ; and ( 5 ) a self-etch adhesive system ( Xeno III ) . Teeth in Group 1 were restored with amalgam and Groups 2 - 5 with polyacid-modified resin-based composite ( Dyract AP ) . The teeth were evaluated clinical ly and radiographically for 24 months . Marginal integrity of the restorations was also recorded at recall periods using modified USPHS/Ryge criteria . RESULTS After 2 years , the overall success rate of direct pulp capping was approximately 93 % ( 78/84 teeth , excluding exfoliations ) . The Dycal and Prime&Bond NT groups did not exhibit any clinical or radiographic failure . A majority of failures were observed in teeth that received NRC and phosphoric acid pretreatments ( Groups 3 and 4 ) . Clinical symptoms were seldom associated with failed teeth . Only one tooth failed in the Xeno III group . Marginal integrity scores were not compatible with the clinical / radiographic outcome
