Burning mouth syndrome in patients with different metal alloys

Objectives: Burning mouth syndrome (BMS) is defined as chronic pain condition characterized with burning in the oral cavity, without accompanying abnormal clinical or laboratory findings. The purpose of our study was to investigate electrical potential and saliva pH levels in patients with burning mouth and with different metal alloys in oral cavity. Methods: Study included 34 patients with burning mouth sensations without any observable oral lesions with at least two different metal alloys (females=23, men=11, mean age=67.56±7.80). The control group consisted of 27 subjects without any sensation in oral cavity and with, also, at least two different metal alloys (females=20, men=7, mean age= 64.69±9.71). Electrical potential was measured with PC controlled milivoltmeter. Milivotmeter software was equipped with algorithms for digital signal processing and filtering. Saliva pH levels were measured using pH test strips with range of 4.5-9.0 (iGen pH). Statistical analyses were performed using SPSS 10.0.5. Results: Mean electrical potential value in BMS group was 133.09±88.14mV while in control group it was 143.18±86.21mV. There was no statistically significant difference in electrical potential between groups (t=0.36 ; p=0.71). Mean pH level in patients with burning sensations was 6.73±0.43 while it was 6.89±0.38 in control group. There was no significant difference in saliva pH level between groups (t=0.27 ; p=0.021). Conclusion: Our study did not show significant difference in electrical potential and saliva pH level between investigated groups. Relevance: Although oral electrical potential and saliva pH level are described as causes of BMS in patients with different metal alloys, failed to prove this association.
