AI speech tools could revolutionise dental record-keeping
But caution is needed, King’s College London study finds.
Artificial intelligence (AI) automatic speech recognition (ASR) tools could dramatically improve how dental professionals record patient information; saving time and reducing administrative burden, according to a study by from King’s College London.
But the study, published in the Journal of Dental Research, added that while the transcriptional accuracy of these tools is high, they can struggle with more technical language and their reliability is not currently sufficient to support unreviewed use.
Researchers tested ten different ASR systems to see how well they could transcribe spoken orthodontic clinical records into written text. The best-performing system was an experimental pipeline combining OpenAI’s GPT-4o transcription with a large language model for error correction, closely followed by the Heidi Health digital scribe and GPT4oTranscribe speech-to-text application programming interface.
Dentists spend significant time typing up clinical notes often during the consultation, which can reduce face-to-face time with patients. ASR tools can allow clinicians to dictate their clinical notes naturally, freeing them up to focus more on direct interaction with the patient. The most advanced systems were faster and more accurate than manual typing, with up to 60% in time savings.
Key findings:
- The AI-enhanced experimental pipeline (GPT4oTranscribeCorrected) had the lowest error rate, especially with technical dental terms.
- Commercial systems like Heidi Health also performed well, but others – such as Dragon Anywhere – had high error rates and even introduced clinically significant mistakes.
- Background noise and accent had minimal impact on the best systems, making them suitable for real-world clinical settings.
While the technology is promising, researchers warn that clinically significant errors – such as misidentifying teeth or treatment plans – can still occur. They recommend a ‘human-in-the-loop’ approach, where clinicians review and edit transcripts rather than relying on them blindly.
“AI speech tools can streamline documentation and improve efficiency, but we must remain vigilant,” said Ruairi O’Kane, the lead author. “Even subtle transcription errors can potentially impact patient care.
The team suggests that future systems should include confidence indicators to flag uncertain terms and be trained on larger, more diverse dental datasets. Ultimately, the goal is to help clinicians become editors of their notes, not just authors, while maintaining safety and accuracy.
