In oral healthcare, early caries diagnosis has long been challenging. Traditional X-ray or CBCT scanners carry ionizing radiation risks and have limited sensitivity for early demineralization and micro-lesions beneath tooth surfaces or below the gumline. An intraoral scanner based on OCT (Optical Coherence Tomography) technology achieves over 90% caries detection accuracy, capturing 3D data volumes including below the gumline, in fluids, and beneath tooth surfaces without radiation, providing revolutionary diagnostic capabilities for dental robotic systems.
However, an OCT probe must enter the confined, curved, and moist environment of the oral cavity, imposing stringent requirements on imaging hardware size, waterproofing, field of view, and macro capability. An ultra-miniature endoscope camera module can serve as the “visual sentinel” for dental robotic systems, assisting in precise positioning, real-time observation, and procedural guidance. The camera module’s diameter, field of view, macro imaging capability, waterproofing, and interface compatibility directly determine whether the dental robotic system can achieve precise, safe, and efficient automated diagnosis and treatment in the oral cavity.
Unlike standard intraoral cameras, an auxiliary camera integrated into a dental robotic system must meet the following demanding requirements:
Extreme Miniaturization: Must enter spaces as narrow as tooth gaps, gingival sulci, and root canals with diameters under 1mm. Camera diameter must be less than 1mm.
Ultra-Wide Field of View: When observing up close deep in the oral cavity, needs to cover the entire crown, gingiva, and adjacent areas, reducing blind spots.
Macro Precision Imaging: Must clearly detect early caries spots, cracks, calculus, etc., at working distances of 3-30mm.
Waterproof and Anti-Fog: The oral cavity contains saliva and water mist; the camera requires IP67 or higher waterproof rating.
Plug-and-Play: Must integrate quickly with the robot’s main control system; UVC driver-free greatly simplifies development.
Based on our understanding of medical endoscopes and precision imaging applications, an embedded 1/31 inch camera module truly suited for dental robotic systems achieves precise alignment across sensor, size, FOV, optics, interface, and protection.
Early lesions in root canal orifices, gingival sulci, and interproximal spaces are hard to see with the naked eye or standard intraoral cameras. Conventional endoscopes have diameters above 2mm and cannot access these narrow spaces.
This 0.16MP Camera Module features the OCHTA10 CMOS sensor with a probe diameter of only 0.95±0.05mm and an IP67 waterproof steel shell. Key advantages:
0.95mm ultra-fine probe: Easily enters root canal orifices (typically 1-1.5mm), gingival sulci (0.5-2mm), and interproximal spaces to observe early caries, cracks, and calculus deposits.
IP67 waterproof steel shell: Resists saliva, irrigants, and steam, allowing routine disinfection for cross-infection control.
Separate structure: Probe separates from the main unit, reducing handheld weight and facilitating flexible robotic arm manipulation.
For dental robotic systems, 0.95mm means “access everywhere”—deep exploration without damaging healthy tooth structure, achieving truly minimally invasive diagnosis.
At working distances of 3-30mm, the camera must simultaneously cover the entire crown and clearly present details like initial demineralization, cracks, and pigmentation on enamel. Ordinary endoscopes have FOVs of only 60-90°, requiring frequent probe movement.
This Wide Angle Camera Module features a 127° diagonal (100°H×100°V) ultra-wide angle paired with a 3-30mm macro-specific optical design. Advantages:
127° ultra-wide angle: At 5-10mm working distance, a single frame covers the entire buccal/lingual surface of a molar or anterior tooth, reducing probe movement and improving scanning efficiency.
3-30mm macro: Optimized for close-up observation, clearly revealing micro-enamel structures at 3mm, such as chalky white spots of early caries, crack trajectories, and calculus morphology.
0.175mm focal length + F2.8 aperture: Ensures sufficient light intake at extremely short focal lengths, with distortion control (< -11%) for true, undistorted imaging.
For OCT-assisted diagnosis, this camera precisely locates suspicious areas, guiding the OCT probe for deeper scanning and improving caries detection rates.
The oral cavity is poorly lit, and OCT scanning may require darkened conditions. The camera needs built-in illumination without causing excessive glare or shadow interference.
The module offers optional Micro USB 5P/Type-C dual interfaces and supports independent LED control. Users can adjust brightness for different tooth surfaces (highly reflective enamel vs. low-reflective gingiva) to achieve uniform, glare-free images. Combined with the OCHTA10 sensor‘s low-light sensitivity, clear images are deliverable even deep in root canals.
Dental robotic system main controllers typically run embedded OS (Linux, Android). The camera module must interface quickly, minimizing driver development.
This USB2.0 Camera Module uses a standard USB 2.0 interface and supports the UVC driver-free protocol. Advantages:
Plug-and-play: Automatically recognized when connected to the main board, no low-level driver coding, significantly shortening product development cycles.
Wide compatibility: Supports Windows, Linux, Android, macOS, adapting to various robot control platforms.
USB power: Single cable handles both power and data, simplifying wiring.
For dental robot manufacturers, UVC means “as easy as a USB drive”—the camera module integrates quickly onto the robot arm, ready to use.
Dental robots run for extended periods; the camera must withstand disinfection, moisture, and minor impacts. The stainless steel shell and IP67 rating ensure reliability under frequent rinsing and steam sterilization. The ultra-fine probe and lightweight design add minimal load to the robotic arm, preserving motion precision.
1. Early Caries Screening: The robot automatically scans the dentition with the camera. The 0.95mm probe enters interproximal spaces and pits/fissures; the 127° wide angle quickly covers tooth surfaces. AI identifies early caries spots with higher accuracy than the naked eye.
2. OCT-Assisted Localization: The camera identifies suspicious areas and guides the OCT probe for deeper 3D imaging, verifying lesion depth and extent with >90% accuracy, avoiding X-ray radiation.
3. Root Canal Therapy Navigation: During root canal preparation, the 0.95mm probe enters the canal orifice to observe orifice location, calcified bridges, and debris, assisting the robot in precise cutting.
4. Periodontal Disease Probing: The probe enters the gingival sulcus (1-2mm depth) to observe calculus distribution, pocket depth, and gingival inflammation, providing visual evidence for periodontal therapy.
The core value of dental robotic systems lies in “radiation-free, high-accuracy caries diagnosis using OCT technology.” Adding a camera module with 0.95mm diameter, 127° ultra-wide angle, 3-30mm macro, IP67 waterproof, and UVC driver-free equips the system with a “pass” to enter the microscopic world of dentistry. Guided by AI, the robot can automatically scan the oral cavity, locate suspicious lesions, and direct precise OCT imaging, dramatically improving early caries detection and treatment efficiency.
