Conclusions MTA cements have a higher success rate , with a lower inflammatory response and a more predictable hard dentin barrier formation  than calcium hydroxide cements .
However , there were no differences , in these parameters , when MTA cement was compared with tricalcium silicate cements .
Dental adhesives systems showed the lowest success rates
Introduction Direct pulp capping therapies use bio material s to protect exposed tissues , inducing repair through the production of a mineralized barrier .
The purpose of this study was to compare the effectiveness of bio material s and techniques by means of a systematic review and meta‐ analysis .
Pulp capping: advantages of using laser technology.
AIM Pulp capping represents the boundary between conservative and endodontic therapy . The importance of this technique , which considerably improves the prognosis of the tooth , justifies the quest for new techniques and technologies : the most recent literature reports more predictable results ( approximately 90 % ) with cappings performed using laser of different wavelengths , compared to traditional procedures , which report a success rate of approximately 60 % . The purpose of this work is to assess the efficiency of laser technology combined with the use of a self-hardening calcium hydroxide base in pulp capping procedures performed on decayed permanent teeth . MATERIAL S AND METHODS This study was carried out on 34 patients , aged between 11 and 18 years ( average 14,5 ) who needed pulp cappings for deep caries affecting permanent teeth ( 8 front and 26 back ) . They were divided into three groups based on the operative protocol employed : traditional technique , laser-assisted technique using Er , Cr : YSGG lasers ( 2780 nm ) and laser assisted technique using Erbium : YAG lasers ( 2940 nm ) ; all patients were asked to return for follow-up visits ( anamnesis , vitality testing and intraoral x-ray ) scheduled at 1 , 3 , 6 , 12 months , 2 and 4 years ; other 30 cases on adult patients ( 19 to 40 years , average 27,1 ) , treated with the same methods , were used as control group . RESULTS Traditional technique group showed a success of 63 % ( adult control group 50 % ) ; Er , Cr : YSGG laser-assisted technique showed a success rate of 80 % ( adult control group 80 % ) ; Erbium : YAG lasers laser-assisted technique showed a success rate of 75 % ( adult control group 70 % ) . All age groups had good success rates with the pulp capping technique , regardless of the technique used . CONCLUSION Laser technology proved effective in improving the prognosis of pulp capping procedures on teeth affected by deep caries pathology
