Improve Dental Diagnosis Accuracy with a Custom AI System
AI improves dental diagnosis by analyzing X-rays to find pathologies invisible to the human eye. This analysis flags potential caries and bone loss.
Syntora enables dental practices to improve diagnosis accuracy by developing custom AI models that analyze X-rays for pathologies. Our engineering engagements build systems that integrate into existing workflows, highlighting potential issues for dentist review rather than replacing professional judgment.
A custom AI diagnostic model is an engineering engagement, not an off-the-shelf product. Syntora would build a system trained on your practice's anonymized radiographs, which allows it to learn the specific nuances of your imaging equipment and patient population. This typically requires a dataset of at least 5,000 historical bitewing and periapical images with confirmed findings to achieve useful accuracy. The scope and timeline of such an engagement are determined by the size and quality of available data, and the specific diagnostic findings the practice aims to address.
What Problem Does This Solve?
Standard dental imaging software that comes with digital sensors, like that from Dexis or Carestream, provides tools for magnification and contrast adjustment, but lacks any real diagnostic intelligence. A dentist must manually scan every surface on every radiograph, a repetitive task prone to human error, especially at the end of a long day. This leads to missed incipient lesions that later require more invasive and costly treatment.
Specialized AI SaaS platforms like Overjet or VideaHealth solve the analysis problem but create a business problem for small practices. Their pricing is typically a recurring monthly fee per provider. For a 4-dentist practice, this can mean thousands per month for a single feature. It also forces an all-or-nothing commitment, where you pay even for associates or hygienists who may only need the tool part-time.
These platforms are also multi-tenant systems trained on data from thousands of practices. Your patient data is used to improve their product, and the model's findings are a black box. You cannot inspect why it flagged a specific area, and it cannot be tuned specifically to your practice's unique patient demographics or equipment profile.
How Would Syntora Approach This?
Syntora's engagement would begin by collecting a dataset of anonymized historical DICOM images from your practice's PACS server. We would sign a HIPAA Business Associate Agreement before any data access. Using libraries such as pydicom in Python, we would extract the image arrays and anonymize all metadata, creating a clean dataset for training.
Our approach involves fine-tuning a pre-trained convolutional neural network, such as a ResNet-50 architecture, using PyTorch. The model would be trained to identify and draw bounding boxes around different classes of findings, including interproximal caries, periapical radiolucencies, and evidence of alveolar bone loss. Performance targets, such as accuracy for caries detection, would be established during the initial discovery phase and iteratively optimized through development and validation against a held-back subset of your data. We have experience building document processing pipelines using similar AI models (for financial documents) and this pattern of image analysis applies directly to dental radiographs.
The trained model would be packaged into a container and exposed via a lightweight FastAPI service. This API would offer an endpoint that accepts a DICOM file and returns JSON containing the coordinates of any detected findings. We would deploy this service on a serverless platform like AWS Lambda, which offers efficient scaling based on demand and predictable operational costs, ensuring all processing happens within a secure, isolated cloud environment.
To integrate the tool directly into your existing workflow, Syntora would develop a small JavaScript plugin for your imaging software. This plugin would add an 'Analyze' button that, when clicked, sends the current X-ray to the secure API. The returned coordinates would then be used to draw colored overlays directly on the image, highlighting areas for the dentist's review. A typical engagement for a system of this complexity, from data collection to deployment, would take approximately 8-12 weeks, depending on data readiness and client-side integration requirements.
What Are the Key Benefits?
A Second Opinion in Under 400 Milliseconds
Get near-instant analysis of any radiograph. Stop spending minutes on manual review and get an AI-powered confirmation before the patient even leaves the chair.
Pay for the Build, Not Per-Dentist, Per-Month
A one-time, fixed-price build means no recurring license fees. The system is yours, with no penalties for adding associates or opening another location.
You Own the Model and the Source Code
We deliver the complete Python source code and the trained model file to your private GitHub repository. You have full ownership and control over your system.
Monitored Performance with Automated Alerts
We use structlog for detailed logging and set up AWS CloudWatch alarms. If the API error rate exceeds 1% or latency surpasses 1 second, we are notified instantly.
Integrates Directly into Your Imaging Viewer
No new software for your staff to learn. The analysis is triggered by a simple button inside the imaging software you already use, whether it's Dentrix, Eaglesoft, or Open Dental.
What Does the Process Look Like?
Data Security and Audit (Week 1)
We sign a HIPAA BAA and you provide a one-time export of anonymized historical DICOM images. We provide a data quality report confirming the dataset is suitable for training.
Model Training and Validation (Weeks 2-3)
We train and validate the diagnostic model on your data. You receive a validation report detailing the model's accuracy, precision, and recall for each type of finding.
Deployment and Integration (Week 4)
We deploy the API to a secure AWS environment and deliver the integration plugin for your imaging software. We work with your team or IT provider to install it.
Clinical Review and Handoff (Weeks 5-8)
Your clinicians use the tool and provide feedback for one final tuning pass. We then deliver the full source code, documentation, and a runbook for future maintenance.
Frequently Asked Questions
- How much does a custom dental AI system cost?
- The cost is a one-time, fixed price based on the number of diagnostic tasks (e.g., caries, bone loss, calculus) and the quality of the initial data. A single-task model for caries detection is a straightforward build. A multi-task model requires more data and a longer training cycle. We provide a firm quote after the initial data audit.
- What happens if the AI analysis fails or the service goes down?
- The system is an aid, not a replacement for a dentist's judgment. If the API is down, the 'Analyze' button in your software is temporarily disabled and we are notified by a PagerDuty alert. No patient data is at risk and your existing workflow is not interrupted. We have a 2-hour service restoration target under our optional maintenance plan.
- How is this different from a SaaS tool like Overjet?
- Overjet is a multi-tenant SaaS product with a recurring per-provider subscription. Syntora builds a single-tenant system that you own outright for a one-time cost. Your model is trained exclusively on your practice's data, ensuring it is tuned to your equipment. There are no recurring license fees, and you own all the code.
- How do you handle HIPAA and patient data privacy?
- We take this very seriously. We sign a HIPAA Business Associate Agreement before starting. All work is done on anonymized data you provide. The production system runs in your own secure AWS account or ours, completely isolated. We never mix data between clients, and you retain full ownership and control of all patient information.
- What if we change our X-ray sensors or imaging software?
- The model is trained to be robust to minor variations in image quality. However, a complete change of sensor technology (e.g., from Schick to Dexis) may require a brief model recalibration. This is a small, scoped project, typically taking less than a week. The core system does not need to be rebuilt.
- Is this system FDA cleared?
- No. The system we build is a clinical decision support tool, not a medical device intended for autonomous diagnosis. It highlights areas of interest for the dentist's review and confirmation. The final diagnostic responsibility always remains with the licensed clinician. This approach avoids the lengthy FDA approval process required for autonomous diagnostic devices.
