Abstract:
In this study we describe the dental status and oral hygiene practices in institutionalized older people and identify factors associated with poor dental status. A cross-sectional study was performed in a nursing home in Fortaleza, the capital of Ceará State (northeast Brazil). The number of decayed, missing, and filled teeth (DMFT) was assessed in the residents of the nursing home (n = 167; mean age = 76.6 years). The mean DMFT value was 29.7; the mean number of missing teeth was 28.4. Ninety-three (58.1%) were edentulous. Almost 90% practiced oral hygiene, but only about half used a toothbrush. Only 8% had visited a dentist in the preceding three months. Most of the variables regarding oral hygiene habits (such as the use of toothbrush, frequency of oral hygiene per day, regular tooth brushing after meals) did not show any significant association with the DMFT. In multivariate regression analysis, age, general literacy level, and practice of oral hygiene were independently associated with the DMFT (R(2) = 0.13). Institutionalized older people in northeast Brazil have poor dental status, and oral hygiene practices are insufficient. Dental health education is needed focusing on the special needs of this neglected and socioeconomically deprived population to improve their quality of life.

Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
