WHERE

Every dental practice can benefit from the use of PARL Assist to aid dentists by identifying and segmenting instances of PARL on periapical radiographs.

WHEN

With this recent clearance, Overjet secures its position as the first and only dental artificial intelligence (AI) provider capable of detecting and outlining instances of PARL on periapical radiographs for patients aged 12 years and older.

WHY

Overjet’s PARL Assist product will identify and alert clinicians in various clinical scenarios, building on preexisting clearances. Two illustrative scenarios include explicitly calling out teeth with carious lesions extending into the pulp alongside a PARL lesion and flagging teeth with preexisting root canal therapy that potentially has unresolved PARL, prompting the clinician to investigate and test clinically.

HOW*

In the development of PARL Assist, Overjet harnessed substantial clinical expertise, rigorous testing, and validation. Expert clinicians annotated tens of thousands of clinically validated instances of PARLs across a diverse range of clinical scenarios to train Overjet’s algorithms. The reference standard testing set, establishing the quality bar for its AI, was meticulously created with multiconsensus agreement by expert US licensed endodontists, according to the company.
