The device is designed for patients who already have CBCT data obtained from a CBCT imaging system for other reasons. DS Core Detect does not generate X-ray images and does not provide an indication for taking such images. The device itself is accessed by the dental practitioner through their dental image viewer. From within the dental viewer the user can view the CBCT with results from the subject device. The device will provide a list of teeth that may potentially have PARL and a corresponding PARL "map" to visualize where the PARL is detected. The user has completely autonomy to confirm or reject a tooth that is flagged by the device as potentially PARL positive. The intended users of the device are trained and licensed dentists. The intended patient population for the device is adult patients with permanent teeth at least age 22. Intended Use/Indications for Use DS Core Detect is a concurrent read, computer assisted detection software intended to aid the dentist in the incidental detection of permanent teeth that may be associated with periapical radiolucencies in CBCT images. The device is not intended as a replacement for a complete dentist's review or a replacement of their clinical judgment. The device is to be used by licensed dentists. The device is designed for patients who already have CBCT data obtained for other {5} reasons. DS Core Detect does not generate X-ray images and does not provide an indication for taking such images. The device is intended for adults aged 22 years and older with permanent teeth. ## Indications for Use Comparison The minor differences in indications for use between the subject and predicate do not constitute a new intended use. Both devices are diagnostic aids for detection of PARL. The primary predicate device provides PARL findings for 2D periapical images whereas the subject device detects PARL positive teeth on a CBCT image. The predicate is indicated for bitewing, periapical, and panoramic radiographs and detects multiple pathologies, restorations, and normal anatomy, whereas the subject device is indicated only for incidental detection of PARL on CBCT. The subject device is also specific with regards to being used with CBCTs that have already been taken for other reasons, for aiding with incidental detection of PARL only. Both devices are SaMD and AI/ML enabled. Both devices are diagnostic aids only, not a replacement for standard of care diagnosis. ## Technological Comparison The main technological difference is that the predicate device provides PARL detection, as well as multiple other detections (anatomy, caries, etc.) for 2D dental radiographs, whereas the subject device provides PARL detection on 3D CBCT images. The predicate device spans a large age range and permanent and primary teeth findings, whereas the subject device is limited to permanent teeth for patients 22 and older. The subject device input is CBCT's taken for other reasons for the incidental detection of PARL, whereas the predicate device has 2D bitewing, periapical, and panoramic images as the input. The subject device will provide a list of teeth that may potentially have PARL which the user must confirm or reject and a corresponding PARL "map" to visualize where the PARL is detected. The predicate device outputs a set of bounding boxes for each finding, including PARL. The minor difference in technological characteristics do not raise a concern of substantial equivalence as demonstrated by the performance testing of the subject device. ## Non-Clinical and/or Clinical Tests Summary & Conclusions The DS Core Detect device underwent comprehensive performance testing including standalone testing and a Multi-Reader Multi-Case Reader Study (MRMC). Software verification and validation testing was completed per applicable standards and agency guidance. DS Core Detect indications detections in two operating points: Standard sensitivity and High sensitivity, whereby sensitivity describes the portion of detected teeth with evidence of periapical radiolucency. The standalone study assessed the performance of the device compared to a consensus ground truth. The MRMC study evaluated reader performance with and without the assistance of the device, in a fully crossed study design. Depending on the operating point, these teeth are detected with the following standalone study accuracy with 95% CI's: {6} 1. Sensitivity: High sensitivity 0.78 [0.74; 0.81], Standard sensitivity 0.66 [0.62; 0.70] 2. Specificity: High sensitivity 0.93 [0.92; 0.94], Standard sensitivity 0.97 [0.97; 0.98] Standalone Study Subgroup performance testing subjects included patients 22 and older from various clinical sites across the U.S., with permanent teeth, with CBCT images. Subgroup reporting included lesion size, age, device, gender, and endodontic treatment status, with results as follows: | Operating point | Group | | \( Sensitivity^1 \) | 95% confi-dence interval | \( Specificity^1 \) | 95% confi-dence interval | | --- | --- | --- | --- | --- | --- | --- | | High sensitivity | Lesion | >8 mm3 | 0.82 | [0.79; 0.86] | 0.93 | [0.92; 0.94] | | | | ≤ 8 mm3 | 0.65 | [0.59; 0.71] | 0.93 | [0.92; 0.94] | | | Age | >52 years | 0.76 | [0.71; 0.80] | 0.95 | [0.94; 0.96] | | | | ≤ 52 years | 0.8 | [0.75; 0.84] | 0.92 | [0.91; 0.93] | | | Device | Orthophos S/SL | 0.76 | [0.72; 0.81] | 0.93 | [0.91; 0.94] | | | | Axeos | 0.80 | [0.75;0.84] | 0.94 | [0.91; 0.94] | | | Gender | Male | 0.78 | [0.73;0.83] | 0.93 | [0.92; 0.95] | | | | Female | 0.79 | [0.74; 0.85] | 0.93 | [0.91; 0.95] | | | Endodontic treatment | Tooth treated | 0.82 | [0.78; 0.86] | 0.82 | [0.77; 0.87] | | | | Tooth un-treated | 0.72 | [0.67; 0.78] | 0.94 | [0.93; 0.95] | | Standard sensitivity | Lesion | >8 mm3 | 0.73 | [0.68; 0.77] | 0.97 | [0.97; 0.98] | | | | ≤ 8 mm3 | 0.50 | [0.43; 0.57] | 0.97 | [0.97; 0.98] | | | Age | >52 years | 0.64 | [0.58; 0.70] | 0.98 | [0.97; 0.98] | | | | ≤ 52 years | 0.68 | [0.62; 0.74] | 0.97 | [0.96; 0.98] | | | Device | Orthophos S/SL | 0.64 | [0.58; 0.69] | 0.97 | [0.96; 0.98] | | | | Axeos | 0.70 | [0.64; 0.76] | 0.98 | [0.97; 0.98] | | | Gender | Male | 0.67 | [0.60; 0.73] | 0.97 | [0.96; 0.98] | | | | Female | 0.70 | [0.64; 0.76] | 0.97 | [0.96; 0.98] | | | Endodontic treatment | Tooth treated | 0.75 | [0.70; 0.80] | 0.90 | [0.86; 0.94] | | | | Tooth un-treated | 0.56 | [0.50; 0.62] | 0.98 | [0.97; 0.98] | | 1 Result of a representative standalone study with 306 CBCTs | | | | | | | The MRMC Tooth Level AUC results are as follows: | Number of U.S. readers = 11 | Unaided | Aided | Difference | | --- | --- | --- | --- | | | OR Model-Based AUC Estimates (95% CIs) | | | | | 0.415 (0.279, 0.550) | 0.639 (0.529, 0.749) | 0.224 (0.124, 0.324) | | | Tooth Level Sensitivity (95% CIs) | | | | | 0.421 (0.281, 0.562) | 0.649 (0.535, 0.763) | 0.227 (0.124, 0.330) | | | Tooth Level Specificity (95% CIs) | | | | | 0.962 (0.928, 0.995) | 0.946 (0.915, 0.976) | -0.016 (-0.034, 0.002) | {7} Page 4 of 4 # Conclusion The standalone and MRMC study results collectively demonstrate that the device is as safe, as effective, and performs as well as or better than the legally marketed predicate device. --- **Source:** [https://fda.innolitics.com/submissions/RA/subpart-b%E2%80%94diagnostic-devices/MYN/K253009](https://fda.innolitics.com/submissions/RA/subpart-b%E2%80%94diagnostic-devices/MYN/K253009) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
