P. Fuentes et al., TREATMENT OF PERIODONTAL FURCATION DEFECTS - CORONALLY POSITIONED FLAP WITH OR WITHOUT CITRIC-ACID ROOT CONDITIONING IN CLASS-II DEFECTS, Journal of clinical periodontology, 20(6), 1993, pp. 425-430
A total of 27 mandibular, buccal class II furcation defects were treat
ed in 16 subjects using a coronally positioned flap procedure, with or
without citric acid conditioning of the root surfaces. The effect of
the therapies was evaluated from a series of soft and hard tissue meas
urements. Mean improvements were slightly greater for acid treated tha
n for non-acid treated defects. However, none of the mean differences
reached statistical significance, indicating that citric acid conditio
ning may not be a necessary part of the regenerative, coronally positi
oned flap procedure in mandibular furcations.
