Frecuencia de las lesiones cervicales no cariosas en los estudiantes de la Facultad de Odontología de la Universidad de Cuenca
(2015) Silva Ulloa, Sebastian; Tamariz Ordoñez, Pablo Esteban
At present with increased prevalence of nonbacterial lesions in which tooth structure is lost at tooth neck level, it has begun to place more worldwide importance of the study of non-carious cervical lesions (abrasion, erosion and abfraction), the same that have not well defined etiology, it has been considered the theory that they are produced by more than one factor, whether mechanical factors, chemical factors, or frictional movements of occlusion, etc. The aim of this study was to determine the frequency of non-carious cervical lesions (NCCL) in students who were attending to Dentistry school of the University of Cuenca. A clinical examination was performed on 105 students selected by convenience who were studying at this school during the period March - August 2015, it was observed that 61.9% of the sample had one or more non-carious cervical lesions, appearing mostly as plate shape, on the buccal side and in the group of premolar tooth
Relationship between dental occlusion and brain activity: a narrative review

Objectives: Occlusal function stimulates different areas of the cerebral cortex. The purpose of this narrative review was to identify the relationship between occlusion and brain activity so as to provide theoretical support to enable future studies on the subject. Study selection, data, and sources: Relevant case-control studies, clinical trials, and systematic reviews available in English were retrieved from the following databases: MEDLINE, PubMed, ScienceDirect, Wiley Online Library, and Biblioteca Virtual en Salud (BVS). Of the 53 articles obtained, 12 were included. Conclusion: The sensorimotor cortex is affected by changes in occlusion. It is speculated that occlusion could play an important role in the development of diseases, from anxiety and stress to Alzheimer’s disease and senile dementia. Further investigations into the interactions between occlusion and brain function are needed to elucidate the parts of the brain that are affected when occlusion is disturbed and to determine whether brain function is altered. Clinical significance: Dentists must consider that alterations in the occlusal pattern during mastication can lead to changes in the activation of different brain regions related to memory, learning, anticipatory pain, and anxiety. This suggests that mastication maintains the integrity of certain brain areas and that it may be a key factor in the onset of neurodegenerative diseases.
