TREATMENT OF PERIODONTAL FURCATION DEFECTS - CORONALLY POSITIONED FLAP WITH OR WITHOUT CITRIC-ACID ROOT CONDITIONING IN CLASS-II DEFECTS

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.
