Ultrasonography as an additional tool to localize impacted canines

Area of Science:

• Dentistry
• Medical Imaging
• Oral Surgery

Background:

• Canine impaction is a frequent dental anomaly requiring accurate localization for effective treatment.
• Conventional 2D radiography has limitations in precisely locating impacted teeth and assessing root resorption.
• Cone-beam computed tomography (CBCT) offers 3D localization but involves significant radiation exposure, especially for pediatric patients.

Purpose of the Study:

• To evaluate the efficacy of intraoral ultrasound (io-US) as a non-invasive imaging tool for locating impacted maxillary canines.
• To compare the diagnostic capabilities of io-US with CBCT in the context of impacted canine cases.
• To explore the potential of io-US in aiding treatment planning for impacted canine teeth.

Main Methods:

• A case series of 4 patients with impacted maxillary canines was studied.
• Patients underwent both CBCT and intraoral ultrasound (io-US) examinations.
• io-US images were compared with CBCT scans for validation of the io-US method.

Main Results:

• Intraoral ultrasound (io-US) demonstrated capability in accurately locating impacted maxillary canines.
• The study validated io-US as a viable imaging modality for impacted canine diagnosis.
• io-US may offer additional benefits in assessing soft tissue and vasculature for surgical planning.

Conclusions:

• Intraoral ultrasound (io-US) is a promising, non-radiating imaging technique for locating impacted canines.
• io-US can serve as a valuable adjunct or alternative to CBCT, reducing radiation exposure.
• Further research into io-US applications in dental diagnostics and surgical planning is warranted.
