Aspectos microbiológicos, histopatológicos e clínicos da cárie radicular

Resumo (EN)

This study reviewed the microbiological, histopathological and clinical aspects of root caries. Dental caries is one of the most significant health problems facing older adults. More than half of the elderly who are dentate are affected with either coronal or root caries, and caries is the primary cause of tooth loss in this population. However, age per se is not considered to be the main reason for caries development on root surfaces. The same main factors as for coronal caries, ie, cariogenic microorganisms, diet and saliva seem to play important roles in root caries development. Due to different anatomy, histology, and chemical composition of the tissues, there may be a higher risk of caries development on root surfaces than on coronal surfaces. In treatment of root surface caries, a causative treatment strategy should be determined. Prevention should focus on oral hygiene, fluoride exposure, and restriction of intake frequency of foods containing sugars or other easily fermentable carbohydrates. When a more invasive treatment is necessary, caries are removed and the cavities are restored with glass ionomer cement or with flowable composites, where aesthetics procedures become indispensable. New materials and techniques are emerging to help with geriatric preventive and restorative needs, but ongoing vigilance for caries will be required in this population, which is experiencing in.
