Introduction:

The furcation lesion is defined as a pathological resorption of the interradicular bone, with the consequent exposure of the furcation, increased risk of bone loss and the onset of difficult-to-treat bone defects, which can be improved with the use of membranes through guided tissue regeneration.

Objective:

To determine the effectiveness of guided tissue regeneration in mandibular dental furcation lesions at the Clínica Estomatológica Provincial “Mártires del Moncada” in Santiago de Cuba, from Septembre 2018 to December 2019.

Method:

A quasi-experimental study of therapeutic intervention was carried out with a sample of 20 patients with mandibular furcation lesions and selected by non-probabilistic purposive sampling. One cluster (study group) received regenerative therapy and the other cluster (control group) was treated conventionally. Both met the diagnostic criteria and were examined before and after the treatments (6 months after treatment and 1 year after treatment).

Results:

after assessed the year of treatment, in group I (study group), bleeding disappeared and probing depth decreased by at least 1 mm in 100% of the cases, type I insertion gain was achieved in 60% of them, with a marked superiority in the control group.

Conclusions:

Treatment with guided tissue regeneration has been shown to be effective in patients treated with furcation lesions in contrast to conventional treatment.
