Therapies applied in molars with different grades of furcation lesions

Abstract

Introduction: the destruction of the support tissues in inter-radicular areas of multi radicular tooth is known as furcation lesion. The goals of those therapies are maintaining the teeth health, function and esthetics.
Objective: to determine the therapy employed in furcation lesions and its relation with their seriousness.
Methods: a transversal study was carried out, with the dental records of patients discharged from the consultations of Periodontics and Integral General Dentistry of the Faculty of Dentistry of the municipality Plaza de la Revolución from January 2009 to May 2011 . The universe was formed by all the 119 molars registered with furcation lesions. The studied variables were: furcation lesion degree according to the Carranza y Newman classification, grouped by seriousness and treatment. The association and relationship among qualitative variables were carried out with Chi square.
Results: the flap with implant, the hemisection and the bicuspidizatión were poorly represented with 7, 6%, 2.5% and 0, 8%, respectively while among the most applied ones were the conventional flap (53, 1%), root planning (26%) and the exodontia (11, 8%). Root planning obtained the supremacy (90, 3%) in the lesions grades I and II and the exodontia (57, 1%) was associated to grades III y IV. p= 0,0004
Conclusions: the predominant therapies were: the conventional flap, root planning and the exodontia. Root planning was the favored therapy for the grades I and II, while the dental extraction was the favored one in grades III and IV.
