Problems solved by technology

[0003] At present, the diagnosis of periodontitis basically relies on the periodontal examination and imaging examinations performed by professional periodontists. However, due to the lack of obvious early symptoms of periodontitis and the lack of awareness of oral health among the general public, many

Embodiment 1

[0059] A method for constructing a scoring table for early prediction of periodontitis, such as figure 1 ,include:

[0060] S10: Data collection, sample information can be collected through questionnaires or directly borrowed from other survey databases related to periodontitis. The sample information includes one-to-one correspondence between periodontitis status information and user information, where the periodontitis status information refers to the periodontitis status of each sample, and the user information refers to the personal information of each individual. The information includes N kinds of variable information that are not necessarily strongly correlated with periodontitis status.

[0061] In this example, the sample information is borrowed from the US National Health and Nutrition Examination Survey (NHANES, National Health and Nutrition Examination Survey) database, see Table 1 for details. During 2013-2014, the population characteristics table of 2802 respond...

Embodiment 2

[0093] Using the construction scheme provided in the first embodiment, a pre-judgment scoring table for early periodontitis is obtained, and its use method will not be repeated here.

Embodiment 3

[0095] A construction system of a periodontitis early prediction scoring table is provided, which is used to realize the above-mentioned embodiments, including:

[0096] The data collection module acquires historical investigation records through questionnaires or directly, and collects sample information, where the sample information includes one-to-one correspondence of periodontitis status information and user information. The user information includes N kinds of variable information.

[0097] The data processing module is used to initially screen variables using single-factor logistic regression, and regularize the variable information through lasso regression to obtain M key variables for predicting the onset of periodontitis, where M is less than or equal to N, and stepwise is used Multivariate logistic regression constructs a scoring system for the above M key variables. The scoring system is then evaluated, and the scoring system is verified through the training set a...

Abstract

The invention provides a construction method and application of a periodontitis early-stage prejudgment scoring table. The construction method comprises the steps of data acquisition, data distribution, scoring system construction and variable screening, scoring system evaluation and column diagram construction, and finally scoring table obtaining. According to the scheme provided by the invention, a simple and effective scoring table can be constructed and is presented in a column diagram mode, a user can pre-judge the probability that a subject suffers from periodontitis through the scoring table without special examination and professional operation, and the method is convenient to use, efficient and high in generalization performance.

Description

technical field [0001] The invention relates to a construction method and application of a periodontitis early prediction scoring table. Background technique [0002] Periodontitis is a common chronic inflammatory disease that occurs in the periodontal supporting tissue. Its main clinical manifestations are periodontal inflammation, gingival bleeding, alveolar bone resorption, and periodontal pocket formation, which eventually lead to tooth loosening and loss. . Severe periodontitis can also cause a systemic inflammatory state, affecting the health of the whole body. Various evidences show that the incidence of periodontitis is closely related to systemic diseases such as diabetes, obesity, cardiovascular and cerebrovascular diseases. Periodontitis is a common disease in my country, and its incidence rate is as high as 85%, which seriously affects the quality of life of patients and brings a huge economic burden to the country. [0003] At present, the diagnosis of periodo...
