Etiology and Causes of Odontogenic Sinusitis
- Odontogenic sinusitis is a secondary type of sinusitis primarily related to dental infections or procedures.
- Gum disease, periapical abscesses, tooth decay, dental trauma, periapical cysts, and sinus tract formation can cause odontogenic sinusitis.
- Poor oral hygiene and untreated dental infections increase the risk of developing odontogenic sinusitis.
- Anaerobic bacteria are more frequently involved in odontogenic sinusitis cases.

Clinical Presentation and Diagnosis of Odontogenic Sinusitis
- Symptoms of odontogenic sinusitis are similar to other forms of sinusitis, including nasal congestion, purulent nasal discharge, facial pain or pressure, and reduced sense of smell.
- Dental pain, foul smell, or recent dental procedure history may suggest odontogenic sinusitis.
- Odontogenic sinusitis is often unilateral, affecting the side with the dental problem.
- Diagnosis requires a multidisciplinary approach, including clinical examination, patient history, and radiological investigation.
- Dental panoramic radiographs, computed tomography scans, and cone-beam computed tomography are used to identify dental pathologies and assess the extent of sinus involvement.

Treatment of Odontogenic Sinusitis
- Treatment involves addressing the underlying dental condition and managing sinus inflammation.
- Dental procedures like root canal treatment, tooth extraction, and periodontal therapy may be necessary.
- Antibiotics, nasal corticosteroids, and nasal irrigation can control symptoms.
- The role of these treatments in definitive treatment is unclear.
- Endoscopic sinus surgery may be required if medical management fails or complications occur.

Prognosis and Complications of Odontogenic Sinusitis
- With appropriate treatment, the prognosis for odontogenic sinusitis is generally good.
- Complications can occur if left untreated or not properly managed, including infection spread to other sinuses, the orbit, or intracranial structures.
- Symptoms progression can significantly affect quality of life.
- Proper treatment and management are crucial for a positive outcome.

Advances in Research and Technology for Odontogenic Sinusitis
- Recent studies have focused on the use of artificial intelligence, machine learning, and deep learning in rhinology to improve diagnosis and treatment planning.
- Multidisciplinary consensus statements have been developed to guide clinical practice and standardize management approaches.
- Research has explored the total times to treatment completion and clinical outcomes in odontogenic sinusitis.
- Ongoing research aims to further understand the pathophysiology, risk factors, and optimal management strategies for this condition.
