AI in healthcare is now playing a life-sustaining role in helping people to get accurate treatment with timely diagnosis of various types of diseases. Similarly, machine learning in healthcare is becoming more imperative covering more types of disorders in the body helping people take precautions and well-timed treatments.

Machine Learning (ML) in dentistry for dental image analysis is playing an important role to find out the conditions of teeth helping doctors to recommend the right treatment. But there are more improvements required in this sub-field of the healthcare sector.

Machine learning algorithms are lying under the hood of high-quality medical training data sets, and with further advances in parallel computing and augmentation of training data sets, ML will improve dental image analysis. So, here we will discuss how dental imaging can be improved with machine learning.

Availability of High-quality Training Data Sets

The most important inputs to improve the accuracy of AI-based model prediction using dental images is – high-quality training data sets, only that can help ML algorithm recognize the patterns and store them in its virtual memory to use in real-life.

As much as quantitative and qualitative data will be used to train the model, the accuracy will improve in machine learning for dental image analysis. And the healthcare training data for such needs is created with proper labeling of objects of interest using the annotation technique to highlight the affected area.

In dentistry, the affected or damaged teeth conditions are outlined in the x-ray images by an experienced radiologist, once such data sets get ready, it is used in ML. The ML algorithm learns from varied types of annotated dental x-rays and learns from such source data, which is further used to detect when shown such x-rays.

Using the Right Machine Learning Algorithm

Machine learning algorithms can only understand and learn the training data sets and its use. If you choose the inapplicable algorithm your AI project will be failed or will give inaccurate results, which has no room in the healthcare sector.

So, train your model with efficient dental image analysis algorithms as per the availability of types of data and model validation system. To improve the machine learning algorithm performance, a huge amount of data is required.

Implementing the CAD and CNN Systems

CAD or Computer-aided design systems are one the with potential AI application in healthcare, helps to analyze the medical images providing the radiologist another reliable opinion as a support to enhance the accuracy of the analysis.

Though commercially available dental CAD systems are available in the market and at the same time research on efficient dental image analysis algorithms continues. Analyze, the dental illness various techniques of image annotation are used.

Semantic segmentation is one of them used for the detection, classification, and segmentation of objects (teeth) in dentistry. Again choosing the right algorithm is again an important aspect to improve the dental imaging analysis.

Convolutional neural networks (CNN) are one of the most successful machine learning algorithms for object recognition in machine learning. It is a variation of a multilayer artificial neural network with a convolutional layer. This algorithm is particularly efficient in extracting features, regardless of their location in the image.

And this algorithm has shown great performance in image recognition and classification. They also have solved the thought-to-be-impossible problem of facial recognition. The amount of healthcare training data is the main concerning factor for CNN.

But with the increase in the number of increasing training data images up to millions, such algorithm starts recognizing the objects with unbelievable precision. Google image search algorithm is the best example of such “data-driven” training.

Yes, off-course improvements in architecture also improve performance and accelerate the training process, but training data again remains the key factor.

State-Of-The-Art Facilities and Practice Use

To improve the performance of machine learning in dentistry the well-sourced architectures for dental image analysis systems are required at the enterprise level. As the performance of the AI model can vary in terms of sensitivity and specificity depending on the task, imaging modality and algorithms used to develop such models.

Hence, a state-of-the-art facility is important to build a suitable model for automated medical imaging analysis machines in dental care and treatment. Similarly, the practice of using the training data in the right algorithm is also crucial to improving the overall performance and accuracy of dental image analysis algorithms.

And acquiring the right training data from the right source at the right price helps to build a fully functional AI-enabled ML model for dental imaging analysis.
