Frequency of tooth brushing as a predictive factor for future kidney function decline.
Tooth brushing is important for maintaining oral health and preventing periodontal diseases (PDs), which commonly arise in patients with chronic kidney disease (CKD). However, the association between tooth brushing frequency and kidney function decline remains unclear.We conducted a retrospective longitudinal study at St Luke’s International Hospital, Japan, and participants who underwent health examinations at the Centre for Preventive Medicine from 2005 to 2011 were included. Participants’ tooth brushing frequencies were assessed; multivariate analyses were conducted using a generalized estimating equation to evaluate the association between tooth brushing frequency and a composite renal outcome-composed of a 25% estimated glomerular filtration rate (eGFR) reduction, an eGFR of
