Objective: To determine the relationship between serum vitamin C and periodontitis as estimated by clinical attachment loss (CAL) in community‐dwelling elderly Japanese. Material and Methods: This analysis was confined to 413 Niigata citizens aged 70 years in whom the data for serum vitamin C and CAL were available. High‐pressure liquid chromatography method was used to ascertain the serum vitamin C levels while CAL was assessed on six sites of all teeth present including third molars by means of pressure‐sensitive probes. Other variables included gender, smoking, toothbrushing frequency, number of teeth present and random blood sugar levels. Results: Serum vitamin C concentration was inversely related to CAL ( r =−0.23, p <0.00005) at bivariate level. Multiple linear regression analysis showed that CAL was 4% greater in subjects with lower serum vitamin C levels than in subjects with higher serum vitamin C levels notwithstanding smoking, diabetes, oral hygiene, gender or number of teeth present. Conclusion: The findings suggested that serum vitamin C might have relatively weak but a statistically significant relationship with periodontitis in this elderly population.
