[Analysis on types and severity of periodontitis in 34 677 patients]
1Department of General Dentistry, Peking University School and Hospital of Stomatology, Beijing 100081, China.
Objective:
To analyze the distribution of types and characteristics of periodontal diseases in 34 677 patients visiting the Department of Periodontology, Peking University School and Hospital of Stomatology.
Methods:
Clinical data of 34 677 patients who had the electronic periodontal examination charts from 2007 to 2012 were collected and analyzed.
Results:
Out of 34 677 patients, 32 517 (93.77%) were diagnosed as chronic periodontitis(CP), 1 642(4.74%) were aggressive periodontitis(AgP) and the rest 518(1.49%) patients were classified into some other types of periodontitis. There were more female patients than male ones. Most of patients were between 25 to 54 years olds. Only 7 306(21.07%) patients had more than two periodontal examination charts which represented regular re-visits to the doctors. The majority of patients had severe periodontitis.
Conclusions:
Most of the patients visiting the Department of Periodontology were older aged and diagnosed chronic periodontitis. They had more severe periodontitis conditions but less re-visits. Therefore it is very important for dentists to enhance the oral health education and make early diagnosis and treatment of periodontal diseases for patients. Dentists also should do more follow-up and maintenance works for patients after the initial treatments.
