@entity1 @entity8718 @entity158
This study investigated the clinical efficacy of a bonded resin composite restoration with and without cuspal coverage for the treatment of @entity158 , cracked teeth. @entity1 in a private dental practice who presented with complaints were selected. Inclusion criteria were sensitivity to cold, biting and a clinically-visible crack after removal of the existing restoration. All 40 teeth were restored with a three-step total etch system ( @entity8718 /Clearfil SA primer/PhotoBond), 20 with cuspal coverage and 20 without. @entity1 were interviewed at one week, five weeks and six months regarding the presence of @entity158 . In addition, the teeth were clinically examined after six months to reveal any sensitivity. At one week, @entity1 reported that 12 teeth (30%) were free of @entity158 and 28 teeth (70%) still had symptoms. At five weeks, @entity1 reported that 25 teeth (62.5%) were free of @entity158 and 13 teeth (32.5%) still had symptoms. Two teeth (5%) needed endodontic treatment after two and five weeks. At six months, @entity1 reported that 30 teeth (75%) were functioning without any complaints. Upon clinical examination, only 20 teeth (50%) were free of symptoms. No statistically significant difference between the results of the teeth treated with and without cuspal coverage could be shown (Fischer's exact test at p<0.05).
