Periodontal status of teeth with crown-root fractures: results two years after adhesive fragment reattachment.
OBJECTIVE
This series of case reports evaluated the impact of adhesive crown-root fragment reattachment in periodontally healthy teeth suffering from crown-root fractures on various parameters of periodontal health over a time course of 2 years.


METHODS
A total of 20 teeth with crown-root fractures in 18 periodontally healthy subjects were evaluated. After open-flap access, crown-root fragments were adhesively reattached to the root stub. In all cases, the vertical difference between the alveolar bone crest and the fracture line was <or=1 mm, i.e. violating the biological width. Subsequently, clinical attachment level (CAL), probing pocket depth (PPD), bleeding on probing (BoP) and gingival index (GI) scores were recorded at 6, 12 and 24 months postoperatively for the restored teeth as well as plaque index (PlI) and periodontal screening index (PSI) values for the whole dentition.


RESULTS
Two years after therapy, recorded CAL, PPD, BoP, GI, PlI and PSI scores revealed healthy periodontal conditions in 18 out of 20 treated teeth. Two teeth had suffered again from fragment fracture due to new traumata.


CONCLUSIONS
Adhesive fragment reattachment in periodontally healthy teeth affected by crown-root fractures had no detrimental impact on periodontal health over a time course of 2 years.
