Chronic Maxillary SinusitisDENTASINUSNCT04085536
Prospective Study on the Efficacy of Exclusive Odontological and Medical Treatment in Chronic Dental Maxillary Sinusitis
A study testing Dental and medical treatment in people with Chronic Maxillary Sinusitis, run by Centre Hospitalier Intercommunal Creteil at 5 sites in France.
Trial summary
The study will be offered to patients for whom chronic maxillary sinusitis will be diagnosed in the first ENT (ear, nose and throat) consultation. These patients will then be seen in a stomatology consultation to determine whether or not a dental cause is objective Read more about this study

About this study
Official title: Multicenter Prospective Longitudinal Study on the Efficacy of Exclusive Odontological and Medical Treatment in the Management of Chronic Dental Maxillary Sinusitis
The study will be offered to patients for whom chronic maxillary sinusitis will be diagnosed in the first ENT (ear, nose and throat) consultation. These patients will then be seen in a stomatology consultation to determine whether or not a dental cause is objective
Read the detailed description
Chronic maxillary sinusitis is an inflammatory condition and/or infectious diseases of the maxillary sinus, which last longer than 12 weeks. Those whose the origin is dental, are well described, and yet under-diagnosed most of the time due to a lack of well-defined diagnostic criteria and literature. There is controversy in the various studies about their prevalence. Their management and in particular the therapeutic sequence, is not the subject of any recommendation and involves only a few clinical studies. Their consequences on the patient's general health and quality of life are important. The lack of knowledge about them often leads to diagnostic errors and therefore to a persistence of symptomatology. Moreover, their complications when they are not or incorrectly treated, although rare, can be dramatic (occulo-orbital or endo-cranial complications for example).
Preliminary work in the form of a retrospective study was carried out within of the Centre Hospitalier intercommunal de Créteil in 2015. In view of the results the investigators wanted to set up a clinical trial with the following objectives measure the prevalence of chronic maxillary sinusitis of dental origin and measure the effectiveness of exclusive dental and medical treatment, which could avoid surgical intervention under general anaesthesia, at the higher morbidity.
- Conditions
- Chronic Maxillary Sinusitis
- Being tested
- Dental and medical treatment
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Dental and medical treatmentProcedure or surgery
If the dental cause of sinusitis is objective, if necessary, dental treatment combined with medical treatment will be carried out.
| Study group | Role | What they receive |
|---|---|---|
| Chronic maxillary sinusitis(for more than 12 weeks) | Other | Patients for whom chronic maxillary sinusitis will be diagnosed in the first ENT consultation, will then be seen in a stomatology consultation to determine whether or not a dental cause is objective. Receives: Procedure: Dental and medical treatment |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of therapeutic successes
Disappearance of symptoms and absence of pus from the meatus observed at the 2nd consultation visit ENT control
Measured: 3 months after the end of dental care
Secondary outcomes (3)
Number of dental origin
Patients whose dental origin has been identified
Measured: 3 months after the end of dental care
Percentage of patients with preserved teeth
Percentage of patients who received conservative treatment of the tooth versus non-conservative dental treatment
Measured: 3 months after the end of dental care
Percentage of each type of dental disease causing chronic maxillary sinusitis
Measure the prevalence of the different dental diseases that cause sinusitis
Measured: 3 months after the end of dental care
