Interpretation of the Standard of Oral Health Survey and Examination Method

I. Background and Significance of Standard-setting

Oral disease is a common disease in our country. It has a high prevalence, affects the health of the whole body and the quality of life, and imposes a huge burden on society and economy. It has become an important public health problem. The World Health Organization (WHO) established the Global Oral Database in 1969, which publishes annual reports on global oral disease epidemic trends. The United States, Japan, the United Kingdom, France, Germany, Italy and other developed countries have established a regular system of organizing oral health epidemiological survey. Oral health survey is the main way and means to obtain national oral health information. Oral health survey is used to collect oral health status of different groups of people and understand oral health status of different periods, so as to provide basis for formulating relevant oral public health policies.

There are many methods and scoring criteria for examining oral health. Since 1971, the World Health Organization (WHO) popularized the Basic Method of Oral Health Survey, more than 130 countries and regions have used this standard to investigate and monitor oral health. Data obtained using this method and standard are recorded in the WHO Oral Health Database for international comparison and monitoring. The oral health survey recommended by the World Health Organization (WHO) was updated to Oral Health Surveys: Basic Methods. 5th ed in 2013, which recorded the examination methods and scoring criteria including dental status, periodontal status, fluorosis, oral mucosal status, dental trauma and denture restoration. However, the WHO standards are too rough and many specific contents are not detailed. For example, the manifestations of each abnormal condition in oral mucosa and the contents of **** fillings and temporary fillings in dental condition are not specified in detail. At the same time, the prevalence of some abnormal oral conditions in China is relatively low and the significance of investigation is not significant; the classification of denture restoration status is not consistent. The types of dental prostheses for residents in China at present. Therefore, the criteria recommended by WHO are not completely suitable for the current oral health epidemiological survey in China.

II. Principles and Main Contents of Standard Starting Grassland

The compilation and formulation of 'Oral Health Survey and Inspection Method' is based on the actual situation of our country at the present stage, taking into account a set of inspection methods and scoring standards of oral health survey that can be compared horizontally with other countries in the world, to guide the national oral epidemiological survey, and to standardize the nationwide or local areas of provinces and municipalities. Oral health examination or oral epidemiological investigation were carried out. 'Oral Health Survey and Examination Method' specifies the condition of oral mucosa, teeth, periodontal condition, dental fluorosis, denture restoration, tooth arrangement and abnormal occlusion, examination instruments, examination methods, evaluation criteria and recording codes, recording methods, and the feeling of carrying out oral health survey. The calculation methods of dyeing prevention measures, quality control and statistical indicators after investigation are also given.

The status of oral mucosa, dental condition, periodontal condition, content of dental fluorosis examination, examination instruments, examination methods, evaluation criteria and record codes, and recording methods in the 'Oral Health Surveys: Basic Methods. 5th ed' of the World Health Organization are mainly formulated within the framework of the relevant contents of the 'Oral Health Surveys: Basic Methods. 5th ed'. It also maintains the consistency with 'GB/T 26343 Technical Specification for Student Health Examination' and 'WS/T 208-2011 Fluorosis Teeth'. The inspection contents, inspection instruments, inspection methods, evaluation criteria and recording codes of denture prosthesis in 'Methods of Oral Health Survey and Examination' are combined with the actual situation of Chinese population at present stage. According to the needs of information analysis and the experience accumulated in the Third National Oral Health Epidemiological Survey Report, the contents, instruments, methods and evaluation criteria of tooth arrangement and occlusal abnormalities in the Methods of Oral Health Survey and Examination were formulated after discussion by experts in various fields. According to the relevant contents of Oral Health Surveys: Basic Methods. 4th ed by WHO, the code and recording method were revised and formulated in combination with the suggestions of orthodontic experts; the infection prevention measures in the Method of Oral Health Survey and Examination were discussed and consulted by experts in various fields of oral health. The opinions of the Hospital Symptom Board should be formulated in accordance with the WS/T313-2009 Hand Hygiene Standards for Medical Personnel; the calculation methods of quality control and statistical indicators in the Method of Oral Health Survey and Examination should be combined with the experience accumulated in the Third National Oral Health Epidemiological Survey Report, and the actual situation should be considered comprehensively. Use needs and specifications, and maintain international comparability to develop.

III. Notes on Key Issues

The contents of oral mucosa status, dental status, periodontal status, dental fluorosis, denture restoration status, dental arrangement and occlusal abnormality in this standard are only applicable to oral health survey for the population, which should be different from clinical examination of dental specialty, and should not be used as the basis for clinical diagnosis of individual cases. Medical personnel conducting oral health surveys can select and refer to the relevant contents of this standard to carry out oral health surveys according to their actual needs, without involving each index in an oral health survey. The calculation method of statistical indicators in this standard only gives the calculation criteria of some commonly used statistical indicators. Medical personnel conducting oral health survey can use the calculation method in this standard as a rule.
