The use of resin-based composite restorations in pulpotomized primary molars.

The purpose of this retrospective clinical study was to report a 12- to 54-month follow-up, in which a resin-based composite filling material was used in direct contact with a fast-setting zinc oxide eugenol cement to restore the function and anatomy of 51 pulpotomized primary molars in 2- to 11-year-old children who needed a Class I or II restoration. Formocresol pulpotomy using Temrex cement was performed in all cases. The total-etch technique was used with: (1) 35% phosphoric acid; (2) OptiBond Solo Plus bonding agent; and (3) Filtek P60/shade B2 resin-based composite material. The restored teeth were sealed with Embrace pit and fissure sealant, monitored, and evaluated with periodic radiographs and clinical exams at 6-month recall visits. The results revealed that none of the 51 pulpotomized primary molars had evidence of periapical or furcation pathosis, recurrent decay, open margins, or broken restorations. In conclusion, this clinical study demonstrated that resin-based composite restorations--combined with the total-etch technique and a fifth-generation bonding agent and in direct contact with a fast-setting zinc oxide eugenol cement were long-lasting, quality clinical alternatives to restore the anatomy and function of pulpotomized primary molars.
