Abstract
This study aims to evaluate the occurrence of the white areas on the mucous membranes of the oral cavity ( lichenoid lesions , leukoplakia , etc.). In the period 2009-2012 484 patients were examined for suspected intolerance of dental materials.
The study selected a group of patients with clinical findings of white areas in the oral cavity. Examined group consisted of 63 women (84 %) and 12 men (16 %).
Mean age was 57.7 years. Patients were performed anamnestic examination , clinical examination of the oral cavity, measuring galvanic currents and voltages , patch tests and test LTT - MELISA ®.
Results: Symptom white areas in descending order occurred on mucous membranes of the cheeks (89 %) , tongue (63 %) , gingiva (25 %) and floor ( 8%). Disability mucosa was in most cases unilateral or laterally asymmetrical ( 56%).
Direct contact between dental materials and mucosal lesions were detected in 52 ( 69 %) patients. In 33 patients, mucosal changes occurred only in the direct contact with dental materials and in 19 patients beyond contact with dental materials.
Mean follow-up was 34 months. For further evaluation, 9 patients were excluded.
In the monitored group of patients (n = 66 ), the dental materials were removed in 47% completely and 26% at least partially. 27% patients remained untreated. In the group of treated patients, improvement was observed in 87.5%.
In the group of untreated patients, improvement was observed in 16.7 %. Conclusion: Removing unwanted dental material from the oral cavity lead to an improvement of almost 90% of patients (p < 0.001).
The occurrence of a galvanic cell in the mouth was significantly higher in investigated group when compared to the normal population ( p < 0.001).
