Artificial intelligence is rapidly growing and transforming health care, dentistry, and other domains, too. From automating radiograph analysis to making clinical diagnoses, AI is helping healthcare professionals to improve diagnostic accuracy and efficiency effectively. Even though many discussions focus on how AI can easily detect diseases, analyse radiographs, and support clinical decision-making. However, many people don’t see the work that happens behind the scenes to train the AI models.
As a dentist working with an AI-based dental company, I had the opportunity to work as a dental annotator, and this role has given me a different perspective on how AI in dentistry actually develops.
MY ROLE IN TRAINING AI TECHNOLOGY
AI tools do not automatically understand dental images or issues in the teeth. They learn by analysing thousands and thousands of labeled images as examples. This is where people like me, the dental annotators, play a crucial role.
In my work, I review dental radiographs and dental images to carefully annotate different conditions and structures. This may include identifying the extent of the caries lesion and restorations, checking the periodontal bone level, and other dental findings. Each annotation helps train the AI system to recognise patterns and improve its diagnostic capabilities.
Working on the data sets as a dental annotator requires not only attention to minor details but also should have strong dental knowledge. Most of the time, interpretation of a radiographic image or a dental image requires careful judgment, especially when the findings are not clear.
USE OF MY CLINICAL KNOWLEDGE IN AI TECHNOLOGY
One of the most exciting aspects of working in AI is utilising my clinical expertise to contribute to technological development. As dentists, we are trained to identify any abnormalities in the oral cavity and to interpret radiographs. We use the same expertise to guide the AI systems during their learning process.
In my experience, in most of the cases, I have noticed that even a missing minor detail in a radiograph or a dental image can significantly impact how the algorithm learns. This experience has reinforced in me that accurate and consistent annotation plays an important role in developing reliable AI tools.
CHALLENGES IN DENTAL ANNOTATION
Even though the work is rewarding and satisfying, using dental knowledge, it also comes with its own challenges. For example, considering dental radiographs, they can vary in quality, and a few times, the differences between normal anatomical variations and pathology can be a bit confusing for an expert, too, because we can estimate the issue only by viewing the radiograph, not by knowing the patient’s chief complaint.
Maintaining consistency and accuracy while annotating large volumes of images requires concentration and thorough dental knowledge. But knowing that these dental annotations contribute to overall improvement in providing accurate diagnoses in dental care through AI tools makes the effort more meaningful.
HOW AI CAN SHAPE THE FUTURE OF DENTISTRY-
AI has the potential to support dentists in numerous ways by overall improving diagnostic accuracy, assisting in treatment planning, and improving workflow efficacy. However, in my experience, I have seen that AI systems heavily depend on the overall quality of the data that is used to train them.
Behind every effectively working AI model is a team effort involving dentists, data scientists, and annotators working together to make sure that the system learns from accurate clinical information.
In my opinion, the future of dentistry is not about AI replacing dentists but about AI supporting dental clinicians to give better diagnoses and to make better and more efficient decisions, ultimately improving patient care.
