MENDIBURU ZAVALA, Celia Elena del Perpetuo Socorro; CARRILLO MENDIBURU, Josué  and  LUGO-ANCONA, Pedro. Relationship between traumatic occlusion and abfractions; their role in pulp disease. Rev. Odont. Mex [online]. 2017, vol.21, n.2, pp.81-86. ISSN 1870-199X.


To determine the relationship between traumatic occlusion and abfractions and their role in pulp disease.


In many teeth lesions might have their onset at the cement and enamel junction; caused by loss of hard tissue, these lesions might appear at vestibular or lingual sides, and are frequently accompanied by tooth sensitivity.

Material and methods

Cross-sectioned observational study with analytical component. Size of sample and inclusion materials: subjects exhibiting dental abfraction caused by traumatic occlusion, who suffered some pulp consequence. Excluded from the study were patients suffering caries, erosions, fillings, previous orthodontic or endodontic treatment, fractures fissures, or dento-alveolar trauma.


The study included 85 patients, out of them 22 exhibited abfractions, gathering a total of 64; 78% showed wear facets. Upper premolars exhibited most prevalent abfractions; 7% presented healthy pulp, 74% pulp disease and 19% periapical compromise.


A relationship was found among variables of traumatic occlusion and abfraction, the aforementioned, in combination with other factors can lead dental pulp to suffer pathological conditions.

Keywords : Traumatic occlusion; abfractions; pulp hypersensitivity.
