Conditions
Summary
Oral potentially malignant disorders (OPMDs) are chronic pathologies which can suffer dysplastic alterations and evolve into oral cancer. The diagnosis of those pathologies is commonly done by visual inspection, which is not capable of determining the presence or not of dysplasia. Furthermore, this type of diagnosis depends greatly on the expertise and training of the professional. In recent years, new methods that can help early oral cancer diagnosis have been developed. A new device has been commercialized, named GOCCLES® (Glasses for Oral Cancer Curing Light Exposed Screening), based on the autofluorescence principle. The hypothesis of this study is that GOCCLES® device could be an effective tool to help in early detection of oral cancer.
Eligibility
Inclusion Criteria3
- Patients older than 18.
- Patients that present oral mucosa injuries compatible with OPMD.
- Patients that understand the purpose of the study and express consent
Exclusion Criteria3
- Patients that don't have the capability to express consent.
- Patients with systemic pathologies that contraindicate a biopsy.
- Patients with a recent biopsy at the oral cavity
Interventions
Inspection using GOCCLES®. An UV light source will be administered, with polymerization lamp sdi radii xpert, with a potency of 1500 mW/cm2 and a wavelength of 440-480nm, applied at 20cm of the injury. Notes will be taken on the location and size of the injury observed with the device. Image register using the GOCCLES® photographic filter for mobile devices. The same light source will be used.
To value the toluidine blue diagnosis capacity, the sequence described by Mashberg will be followed: The patient will realize a mouthwash with acetic acid at 1% for 20 seconds. Two using water for 20 seconds. Toluidine blue at 1% will be applied for 20 seconds. New mouthwash with acetic acid for 60 seconds and a final mouthwash with water. Notes on the and pictures will be taken on the location and size of the injury.
The area to biopsy will be chosen, and, using local anaesthesia, it will be resected. The specimens will be sent to the oral and maxillofacial pathology diagnostic service of the University of Basque Country for anatomopathological study
