ABSTRACT: Recently, bruxism became the center of attention for the etiological research of non-carious cervical lesions (NCCLs). The present study aims to investigate the presence and types of NCCLs associated with bruxism. Retrospective keywords search of the clinical notes of all patient charts in axiUmTM was performed using the terms “bruxism”, “attrition”, “abrasion”, “erosion”, and “abfraction”. All bruxer patients 18 years and older who presented to the UNLV School of Dental Medicine (01/01/2014 to 09/30/2018) with the complete record were included. To determine the statistical analysis implications, the chi-square test was used. Commonest types of NCCL associated with bruxism were attrition and abfraction. Five hundred seventeen cases had multifactorial lesions. Anterior maxillary teeth followed by mandibular anterior were the most affected teeth. Abfraction lesions were mainly sighted in maxillary premolars, followed by maxillary canines. Within the limitation of the present investigation, it was concluded that attrition and abfraction were highly associated with bruxism.
