Erosive lesions in patients with alcoholism.

BACKGROUND

The authors conducted a study to determine the occurrence of erosive tooth lesions in patients with alcoholism and to establish the influence of salivary flow rates and pH levels on their appearance.

METHODS

The authors conducted a cross-sectional study in 140 participants (70 with clinically diagnosed alcoholism who were undergoing therapy for their addiction were in the test group and 70 who did not consume alcohol were in the control group). The authors determined the participants' salivary statuses by measuring the flow rates and pH levels of both unstimulated and stimulated saliva.

RESULTS

The authors found more erosive lesions in the test group (P < .01). They detected a higher number of erosive lesions in participants in the test group who had a pH range of 5 to 6 compared with a pH range of 6 to 7 (P = .01). They found a significant correlation between alcoholism and unstimulated salivary flow rate (P < .05).

CONCLUSIONS

The salivary flow rate was similar in control and test groups. The prevalence of erosion in the test group was higher than that in the control group, which may be related to the decrease in salivary pH of both stimulated and unstimulated saliva in this group. The results of the study showed no connection between erosion prevalence and pH levels and stimulated salivary flow rates.

CLINICAL IMPLICATIONS

Patients with alcoholism may be at risk of developing erosive lesions on their teeth owing to the low pH level of their oral environment and decreased saliva levels.
