To present frequency of periapical healing in mandibular molars after root end resections sealed with dentin bonded resin composite.
N=639 mandibular molars, treated over sept 1984-march 1997 due to apical periodontitis.
-teeth underwent apicoectomies, and retrofills with gluma and retroplast.
-success criteria by Rud et al.
–complete healing: complete PDL regeneration.
–uncertain healing: decrease lesion size or lesion size unchanged <4 yrs.
–failure: unchanged lesion size >4yrs or increase in size.
-recall ranged 6 mo-12.5yrs.
-92% complete healing, 1 % uncertain healing, 7% failure.
-no significant differences between first, second, third mandibular molars or mandibular first molar mesial/distal root
successes (P> .05).
-of 25 failed teeth that underwent re-surgery, saw 80% complete healing.
Root end sealing of mandibular molars with dentin bonded resin composite retrofill is a promising technique.
