Background: Often times, the oral health care of chronic renal failure patients are often neglected, leaving such patients with serious complaints. Tooth wear lesion is one of such problems which are often complicated with dentinal and pulpal exposure. Little is known about its distribution and clinical implications in renal patients. Methodology: This cross-sectional study was conducted among chronic kidney patients being managed with medication and hemodialysis attending at the renal Unit of the Obafemi Awolowo University, IleIfe. The participants were selected using simple random methods from among the pool of patients receiving treatment in the Renal clinic. Biodata of each patient was recorded. They were also interviewed for presence of oral complaints and other systemic problems. Oral examination was then conducted on each participant, each tooth was examined for tooth wear lesion and other oral problems. Blood sample was also taken for blood creatinine and urea. Data was analyzed using STATA 14. Results: A total of 130 (99 male and 31 female) renal patients participated in the study out of which 120 (92.3%) had form of tooth wear lesions. Majority of those with oral lesion were above 60 years old. Tooth wear lesion see were dental tooth wear lesion see were dental erosion (95), attrition and abrasion. More than half (63, 52.5%) of the tooth wear lesions were seen in the lower posterior teeth, followed by lower anterior teeth and upper anterior teeth. Higher concentration of creatinine and urea was associated with presence of tooth wear lesion. Lesions seen with renal patients with oral lesion are dentine hypersensitivity, gingival recession. Others are tooth ache, halitosis and tooth mobility. Conclusion: Prevalence of tooth wear lesion in renal patients was 92.3%. The most frequent tooth wear lesion seen was dental erosion. The teeth in the lower posterior segment of the mouth was the most frequently affected. The blood urea and creatinine concentration were significantly higher in patients with tooth wear lesion.
