Study may explain why people with diabetes may develop tooth decay.
People with both Type 1 and Type 2 diabetes are prone to tooth decay, and a new study from Rutgers suggests that the cause may be reduced strength and durability of enamel and dentin, the hard substance under enamel that gives structure to teeth.
Researchers induced Type 1 diabetes in 35 mice and compared their teeth with those of 35 healthy mice over 28 weeks. The study found that enamel grew significantly softer in the diabetic mice after 12 weeks, and the gap continued to widen throughout the study. Significant differences in dentin microhardness arose by week 28.
