Oral health problems such as periodontal disease, dental caries, and tooth loss have been suggested to have associations with cardiovascular disease. This study aimed to evaluate whether oral hygiene behaviour can alleviate cardiovascular risk associated with oral health status using a nationwide population-based cohort. The data of 247 696 healthy adults aged 40 years or older who underwent an oral health screening programme and had no history of major cardiovascular events were extracted from the National Health Insurance System-National Health Screening Cohort. After a median follow-up of 9.5 years, 14 893 major cardiovascular events occurred including cardiac death, myocardial infarction, stroke, and heart failure. The risk of cardiovascular events was higher when a subject had periodontal disease, a higher number of dental caries, or more tooth loss. Performing one more tooth brushing a day was associated with a 9% significantly lower risk of cardiovascular events after multivariable adjustment. Regular dental visits (once a year or more) for professional cleaning were also shown to reduce cardiovascular risk by 14%. Improved oral hygiene behaviours were shown to attenuate the cardiovascular risk originating from periodontal disease, dental caries, and tooth loss. Oral hygiene care such as frequent tooth brushing and regular dental visits for professional cleaning reduced the risk of future cardiovascular events in healthy adults. This study also suggests that improved oral hygiene behaviour may modify the association between oral health and cardiovascular diseases.

The purpose of this study was to evaluate the efficacy of the alveolar ridge preservation technique using collagen sponge and xenograft after extraction. Twenty patients were divided into the control group and the experimental group, which contained about 10 patients each. The control group patients were planned 3-unit bridge without performing implant and without special treatments for the extraction socket, and prosthetic treatments were performed after 3 months. In the experimental group, using collagen sponge and xenogeneic bone graft, alveolar ridge preservation was performed simultaneously with tooth extraction; implants were placed after 3 months. Clinical and histological evaluations and statistical analysis were performed. The resorption rate of the width of alveolar bone 3 mm below the alveolar ridge of the control group was shown to be 20.74% and of the experimental group was an average of 14.26%, approximately a difference of 6% was observed, and it was statistically significant. New bone formation in the vicinity of bone graft materials was achieved well, and inflammation findings were not observed. The results indicated that in the ridge preservation using collagen sponge and xenograft, xenograft prevents the horizontal resorption of the alveolar ridge, and the upper collagen sponge blocks the infiltration of soft tissues to the lower area, and thus it has the advantage of the enhancement of bone fill.
