摘要

Aim

Although diabetes is associated with the risk of tooth loss, there are no large-scale studies examining the reality and the effectiveness of dental maintenance visits in preventing tooth loss. We aimed to investigate the associations among the number of teeth, dental maintenance visits and diabetic status.

Methods

This is a cross-sectional study: a database comprising employment-based health insurance claim and medical check-up data between April 2015 and March 2016. From the dental receipts for a total of 705,542 individuals aged 20–74 years, we calculated dental visits ratio. After excluding missing data on the number of teeth and HbA1c, the association between dental maintenance visits and the number of teeth was further examined in 185,820 individuals aged 40–69 years visited a dentist by diabetes status.

Results

The percentage of dental visits was 46% overall, particularly low among younger subjects (34% in 20 s, 43% in 30 s), and increased with age. The maintenance-included group had a higher number of teeth than the treatment-only group, even at older ages, and this association was observed regardless of diabetes or glycemic control status. Furthermore, even with diabetes, the number of teeth in the group with good glycemic control was like that of non-diabetic.

Conclusion

Dental visits ratio was particularly low among younger subjects and those who receive dental maintenance had a higher number of teeth, regardless of diabetes or not. Adequate glycemic control and dental maintenance were associated with the number of teeth in the people with diabetes. The results suggest that it is important for physicians to work closely with dentists to promote patient-centered care and encourage both maintenance visits and better glycemic control.
