Purpose:
A clinical survey was made on the life style and dietary behaviors of people with non-periodontal disease and people with periodontal disease for prevention and treatment of periodontal diseases.
Methods:
72-hour diet analysis and frequency analysis of dietary intake were performed in 60 patients with moderate-to-severe periodontal disease and 60 patients with healthy periodontal tissues randomly selected in the Ninth People's Hospital for dental treatment. The data was analyzed by Student's t test and Chi-square test with SPSS13.0 software package.
Results:
There was significant difference (P<0.05) in vitamin C, flavonoids and β-carotene dietary intake between control group and periodontal disease group; In periodontal disease group, dietary intake of selenium and zinc intake was different from the normal control, but the difference was not statistically significant (P>0.05).
Conclusions:
There is a close relationship between oral health and antioxidant nutrients. Lower dietary vitamin C content, flavonoid content and β-carotene intake lead to destruction of periodontal tissue and higher incidence of periodontal disease.

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...
Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
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.
Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
Peptic ulcers can also be...
