Purpose: (1) to document changes in periodontal parameters in teeth with apical surgery over a long-term period of 5 years.
(2) to correlate the documented changes with patient, tooth, and treatment-related co-variables.
N= 186 teeth.
•242 patients who underwent apical surgery from 2000 to 2004.
•After the Surgical procedure All patients were given nonsteroidal analgesics and were instructed to rinse their mouth twice daily with 0.1% chlorohexidine-digluconate for 10 days. Antibiotics was administered mainly for medical reasons if needed.
•Recalled 1-5 years after apical surgery for follow-up examinations. •Periodontal parameters (PD, GM, and CAL)were collected at baseline and1-5 years after surgery. •Secondary study variables: (1) age (2) sex (3) smoking (4) type of treated tooth and restoration (6) type of incision technique and
Most highlighted Results:
•GM recession and CA loss during the first year after surgery were more significant at the facial sites. However, between 1-5 years after surgery no significant changes in PD, GM, CAL were observed for all teeth.
The surgery itself appears to account for changes observed during the first year, whereas patient- and healing-related factors seem to affect periodontal changes seen thereafter
