Description

Technical Field

[0001] The present invention relates to the technical field of control systems, and particularly to an adaptive dental cleaning adjustment system and a dental comprehensive treatment machine using the same. Background Art

[0002] In dental treatment, dental cleaning is a routine and important operation, mainly used to remove dental plaque, dental calculus and soft deposits on the tooth surface to prevent the occurrence of gingival inflammation and periodontal disease. However, the traditional dental cleaning technology has the following main problems, which affect the effectiveness of treatment and the comfort of patients.

[0003] For example, a stepless water pressure adjustment device and a dental cleaner disclosed in Chinese Patent CN211043982U can change the water pressure at any time according to the usage requirements to achieve the best flushing effect and obtain the best usage experience. However, it lacks the detection and evaluation of the patient's oral cavity and the adaptive adjustment of the dental cleaning process, resulting in defects such as poor accuracy and lack of adaptive adjustment ability during the dental cleaning process.

[0004] At the same time, the following defects also exist in the prior art:

[0005] 1. Traditional dental cleaning equipment usually relies on manual setting of fixed water pressure, flow rate and flushing angle. This "generalized" operation mode cannot adapt to the individual differences of different patients, such as the sensitivity of the gums and the differences in tooth structure. The use of fixed parameters will cause discomfort to some patients or cannot completely remove the dirt on the tooth surface, affecting the treatment effect.

[0006] 2. The current dental cleaning equipment lacks the ability of real-time monitoring and feedback. Doctors usually can only adjust the parameters during the dental cleaning process through the subjective feedback or experience of patients.

[0007] 3. Since the oral health status and treatment needs of each patient are different, traditional dental cleaning equipment cannot perform personalized treatment according to the specific situation of individuals. For example, some patients need a higher water pressure to remove stubborn dental calculus, while others need a gentler treatment due to sensitive gums.

[0008] 4. During the traditional dental cleaning process, the data collection and utilization of the oral state are relatively limited. Even if some equipment has basic state detection capabilities, most of them only collect single data and cannot form a comprehensive oral health assessment.

[0009] In order to solve the problems generally existing in this field, such as weak adaptive adjustment ability, excessive dependence on manual subjectivity or experience, inability to adjust the flushing angle, inability to evaluate the oral cavity, low intelligence, inability to adjust the parameters of dental cleaning, etc., the present invention is made.

[0062] The oral state sensing module collects the state data of the patient's oral cavity. The oral assessment module evaluates the patient's oral state based on the state data collected by the oral state sensing module to form an assessment result. The intelligent adjustment module adjusts the dental cleaning process of the patient's oral cavity according to the assessment result;

[0063] The adaptive dental cleaning adjustment system further includes a central processing unit. The central processing unit is respectively connected to the oral state sensing module, the oral assessment module, the intelligent adjustment module, and the server for control, and centrally controls the oral state sensing module, the oral assessment module, and the intelligent adjustment module based on the central processing unit, and stores the control data of the central processing unit in the database of the server to improve the accuracy and reliability of the adjustment of the entire system;

[0064] The intelligent adjustment module includes a dental cleaner, an adjustment analysis unit, a water pressure adjustment unit, a suction adjustment unit, an angle adjustment unit 1, and a drug injection adjustment unit. The adjustment analysis unit analyzes the adjustment parameters according to the assessment result to form an analysis result.

The suction adjustment unit adjusts the suction of the waste liquid in the oral cavity according to the analysis result. The angle adjustment unit adjusts the flushing angle of the dental cleaner according to the operation data of the medical staff. The drug injection adjustment unit injects the treatment drug onto the surface of the currently cleaned tooth 31 according to the analysis result and adjusts the drug injection amount;

[0065] In this embodiment, the patient needs to collect the state of the oral cavity through the oral state sensing module and obtain the specific oral state, so as to realize the assessment and adjustment of the oral cleaning process;

[0066] In addition, if the dental cleaning operation is performed without collecting the state of the oral cavity through the oral state sensing, the intelligent adjustment module will perform operations such as water pressure adjustment, suction, and drug injection with fixed parameters;

[0067] Optionally, the oral state perception module includes an occlusal seat 26, a detection unit and a memory, wherein the occlusal seat 26 is placed in the oral cavity of the patient and supports the detection unit, the detection unit collects state data in the oral cavity of the patient, and the memory stores the state data of the oral cavity collected by the detection unit;

[0068] The detection unit is arranged on the occlusal seat 26, and includes a pH sensor 28, an odor sensor 29, an α pressure sensor and a camera 27. The pH sensor 28 is used to measure the pH value in the oral cavity, the odor sensor 29 is used to detect the concentration of volatile organic compounds in the oral cavity, the α pressure sensor is used to detect the force data of the gums and teeth 31 when they contact the detection seat, and the camera 27 is used to collect image data of the inside of the patient's oral cavity;

[0070] Meanwhile, in this embodiment, the pressure sensors are arranged on the upper and lower end surfaces of the occlusal seat 26 and are adapted to the number of the patient's teeth 31;

[0071] The bite seat 26 is configured as a disposable item and is used exclusively by one person to prevent cross infection between different patients;

[0072] In this embodiment, the patient needs to place the oral state sensing module in the oral cavity before teeth cleaning, and the oral state sensing module is used to collect the state in the oral cavity, so as to achieve accurate collection of the patient's oral state;

[0073] During the collection process, the patient opens his / her mouth, and the camera 27 collects image data in the mouth (images of the upper palate, tongue coating, gums, and end surfaces of teeth 31), and the pH sensor 28, the odor sensor 29, and the α pressure sensor collect the pH value, organic compound concentration (oral odor), and force data in the patient's mouth;

[0074] In this embodiment, the state data includes pH, organic compound concentration (oral odor), force data, and image data;

[0075] In addition, the α pressure sensor detects the force data of the gums and teeth 31 when they contact the detection seat, which is used to evaluate the bite force and the sensitivity of the teeth 31, so that in the subsequent cleaning process of the teeth 31 and gums, the flushing parameters can be appropriately adjusted to improve the comfort of the patient during the cleaning process;

[0076] Optionally, the oral assessment module obtains the status data collected by the oral status perception module, processes the obtained status data at the same time, and calculates the oral status index Dirty of the patient according to the following formula:

[0077]

[0078] In the formula, pH is the detected acidity and alkalinity, and its value is collected by a pH sensor; VOC is the concentration of volatile organic compounds, and its value is collected by the odor sensor; F is the force data of teeth and gums, and I is the image data index in the patient's oral cavity;

[0079] The oral assessment module processes the obtained force data and processes the force data F of the teeth and gums;

[0080] Among them, the force data F of the teeth and gums is calculated according to the following formula:

[0081]

[0082] In the formula, N is the total number of α pressure sensors, F i is the force value measured by the i-th α pressure sensor, and Sensitive i is the sensitivity index of the area corresponding to the i-th α pressure sensor, and its value is calculated according to the following formula:

[0083]

[0084] In the formula, R 低-中 is the ratio between the force values measured by the i-th pressure sensor under low-pressure conditions and medium-pressure conditions, and R 中-高 is the ratio between the force values measured by the i-th pressure sensor under medium-pressure conditions and high-pressure conditions;

[0085] Among them, the ratio R 低-中 between the force values measured by the i-th pressure sensor under low-pressure conditions and medium-pressure conditions is calculated according to the following formula:

[0086]

[0087] In the formula, is the i-th pressure sensor, is the force value measured by the i-th pressure sensor under low-pressure conditions, and low pressure usually represents a slight biting force, is the force value measured by the i-th pressure sensor under medium-pressure conditions, and medium pressure usually simulates a normal biting force;

[0088] The ratio R between the force values measured by the i-th pressure sensor under medium-pressure conditions and high-pressure conditions 中-高 , is calculated according to the following formula:

[0089]

[0090] In the formula, is the force value measured by the i-th pressure sensor under medium-pressure conditions. Medium pressure is usually the normal biting force, is the force value measured by the i-th pressure sensor under high-pressure conditions. High pressure usually represents a stronger biting force, causing discomfort in sensitive areas;

[0091] In this embodiment, the normal biting force range for adults is usually between 300 and 600 Newtons (N), but depending on individual differences, the biting force can fluctuate between 100 and 1000 Newtons (N);

[0092] Children and the elderly: The biting force of children and the elderly is usually lower than that of adults. For children, it is between 50 and 300 Newtons, and for the elderly, due to tooth wear or gum recession, the biting force weakens and is usually between 100 and 400 Newtons;

[0093] In this embodiment, an example of the values of low, medium, and high biting pressures is provided. Specifically:

[0094] 1) Low pressure:

[0095] A slight biting force, usually representing the force when gently closing the teeth or lightly biting soft objects in daily life. The typical value range is 30 to 100 Newtons (N);

[0096] Usage scenario: Measuring the force on the teeth when gently closing or lightly biting soft foods (such as bananas, bread);

[0097] 2) Medium pressure:

[0098] Simulating the normal biting force, representing the force when chewing harder foods or naturally closing the teeth in daily life. The typical value range is 150 to 300 Newtons (N);

[0099] 3) High pressure:

[0100] A stronger biting force, representing the force when biting hard objects (such as nut shells, hard candies) or unconsciously grinding the teeth. The typical value range is 400 to 600 Newtons (N) or higher;

[0101] In this example, in combination with actual clinical applications, the range of the biting force can be adjusted according to the specific situation of the patient; for example:

[0102] For children: The low pressure can be set to 20 - 50 Newtons, the medium pressure to 50 - 150 Newtons, and the high pressure to 150 - 300 Newtons:

[0103] For the elderly or patients with weak teeth: The low pressure can be set to 20 - 50 Newtons, the medium pressure to 50 - 200 Newtons, and the high pressure to 200 - 400 Newtons:

[0104] Among them, the oral evaluation module processes the obtained image data to process according to the image data index I in the patient's oral cavity, and calculates according to the following formula;

[0105]

[0106] In the formula, I plaque is the dental plaque coverage rate, and its value is the proportion of the plaque coverage on the tooth surface calculated through image segmentation and analysis. I caries is the caries area ratio, and its value is the ratio of the caries area to the total tooth area obtained through image analysis. I gingivitis is the gingival inflammation area ratio, and its value is the ratio of the gingival inflammation area calculated through image analysis;

[0107] Specifically: The oral evaluation module processes the obtained image data according to the following steps:

[0108] S1. Obtain the image:

[0109] Use a high - resolution camera 27 to obtain an image of the oral cavity;

[0110] Among them, the image needs to be clear enough to clearly show the teeth, the gingival surface and its details, and avoid over - exposure, blurring or noise interference;

[0111] S2. Image pre - processing:

[0112] Denoising: Use filtering techniques (such as Gaussian filtering, bilateral filtering) to remove the noise in the image and enhance the smoothness of the image;

[0113] Enhance contrast: Enhance the contrast of the image through histogram equalization or CLAHE (contrast - limited adaptive histogram equalization) to make areas such as teeth, dental plaque and caries more prominent;

[0114] Color correction: Perform white - balance adjustment to ensure that the image color is consistent with the actual oral color for subsequent color analysis;

[0115] S3. Image segmentation:

[0116] 3.1 Segmentation of tooth and gingival regions:

[0117] Color segmentation: By using color space conversion (such as converting from RGB to Lab or HSV color space), the tooth and gum regions are separated from the background based on color differences;

[0118] Edge detection: Using edge detection algorithms (such as Canny edge detection) to identify the contours of teeth and gums, further clarifying the region boundaries;

[0119] Region growing: Based on the preliminary segmentation results, applying region growing algorithms or threshold-based methods to finely segment the tooth and gum regions;

[0120] 3.2 Feature region annotation:

[0121] 3.2.1 Dental plaque coverage rate I plaque :

[0122] Color recognition: Dental plaque usually shows obvious color differences (such as yellow-brown), and color thresholding method is used to identify the plaque region;

[0123] Contour extraction: Using edge detection algorithms (such as Canny edge detection) or contour detection algorithms (such as Sobel operator) to extract the boundaries of the dental plaque region;

[0124] Labeled area: The extracted plaque region is labeled, and the plaque region can be colored on the image for visualization and subsequent processing;

[0125] Region annotation: The identified dental plaque region is labeled, and the number of pixels of the plaque region, PlaquePixels, is calculated;

[0126] In this embodiment, the number of white pixels marked as the plaque region in the binary image is counted, and these pixel numbers are the pixel numbers of the plaque region, PlaquePixels:

[0127] Among them, the coverage rate I plaque is calculated according to the following formula:

[0128]

[0129] In the formula, TotalToothPixels is the total number of pixels of the entire tooth region;

[0130] The edge extraction and region annotation are well-known to those skilled in the art and are obtained through image processing techniques, which are well-known technical means in this field. Those skilled in the art can query relevant technical manuals to know this technology, so it will not be elaborated one by one in this embodiment;

[0131] 3.2.2 Caries area ratio Icaries:

[0132] Color and brightness analysis: Dental caries usually appear as black or dark areas; these low-brightness areas are identified through color and brightness analysis;

[0133] Morphological processing: Morphological operations (such as opening or closing operations) are applied to remove noise and small artifacts, making the caries area clearer;

[0134] Opening operation: Used to remove small noise points and maintain the integrity of the caries area;

[0135] Closing operation: Used to fill small holes and connect adjacent caries areas;

[0136] Region annotation: Edge detection algorithms (such as Canny edge detection) are used to extract the boundaries of the caries area, and the extracted caries area is annotated and displayed on the image for visual inspection;

[0137] In addition, calculating the number of pixels in the caries area CariesPixels is done by counting the number of white pixels marked as the caries area in the binary image, that is, CariesPixels. Here, all pixels in the binary image are traversed, and pixels with a value of 1 are counted to obtain the total number of pixels in the caries area;

[0138] Among them, the caries area ratio I caries is calculated according to the following formula:

[0139]

[0140] In the formula, TotalToothPixels is the total number of pixels in the entire tooth area;

[0141] In this embodiment, the opening operation, closing operation, edge extraction, and region annotation are well-known to those skilled in the art and are obtained through image processing techniques, which are well-known technical means in the art. Those skilled in the art can query relevant technical manuals to know this technology, so it will not be elaborated one by one in this embodiment;

[0142] 3.2.3 Gingival inflammation area ratio I gingivitis :

[0143] Color analysis: Inflammatory areas usually appear red and swollen. The red channel or the a channel (red-green channel) in the Lab color space is used to identify the gingival inflammation area; among them, in the Lab space: the a channel is usually used to separate red (positive value) and green (negative value);

[0144] Setting the threshold: According to the color characteristics of the inflammatory area, a threshold range is set in the selected color space to segment the pixels that may belong to the inflammation;
