Abstract
BACKGROUND Our previous study has shown that cryogun cryotherapy is a good and effective treatment modality for oral leukoplakia. METHODS In this study, we used cryogun cryotherapy to treat 72 oral leukoplakia and adjacent smoking-induced melanosis (OLM) lesions on the buccal mucosae. RESULTS Of 72 OLM lesions, 14 had epithelial hyperplasia with parakeratosis, 24 had epithelial hyperplasia with hyperkeratosis, 26 had mild dysplasia, seven had moderate dysplasia, and one had severe dysplasia. Complete regression was achieved in all 72 OLM lesions after a mean of 3.3 ± 1.3 cryogun cryotherapy treatments. We found that OLM lesions in patients without smoking habit, with the greatest diameter < 2.8 cm, with epithelial dysplasia, or with a surface keratin thickness ≤ 50 μm needed significantly fewer mean number of cryogun cryotherapy treatment to achieve complete regression than those OLM lesions in patients with smoking habit, with the greatest diameter ≥ 2.8 cm, without epithelial dysplasia, or with a surface keratin thickness > 50 μm (all P-values < 0.001), respectively. Univariate logistic regression analyses showed that the greatest diameter, epithelial dysplasia, smoking habit, and surface keratin thickness were the factors influencing the cryogun cryotherapy treatment number (all P-values < 0.001). However, only the greatest diameter < 2.8 cm (P < 0.001) was an independent factor influencing the number of cryogun cryotherapy treatment required to achieve complete regression of the OLM lesion by multivariate logistic regression analyses. CONCLUSION Cryogun cryotherapy is an effective treatment modality for OLM lesions.

Abstract
BACKGROUND Tissue cooling has long been used in the management of both acute and chronic pain. OBJECTIVE To determine whether the application of cryotherapy can reduce the pain of patients with minor form of recurrent aphthous stomatitis. STUDY DESIGN Twenty adult patients who had 2 discrete aphthous stomatitides in the labial mucosa at the same time were included in this prospective, randomized, and placebo-controlled study. One of the 2 aphthous stomatitides was treated with cryotherapy, the other serving as a control. The pain of aphthous stomatitis was scored by the patient on a 6-point scale (from 0 to 5). The size of the aphthous stomatitis was also measured. RESULTS At any interval, no statistical difference was found between the cryotherapy-treated aphthous stomatitis and the control in the change in the value of pain severity, nor was any statistical difference found in the change in the size of the aphthous stomatitis. However, a trend toward less pain in the aphthous stomatitis receiving cryotherapy was noted. CONCLUSION These results suggest that application of cryotherapy on minor form of recurrent oral aphthous stomatitis has no beneficial analgesic effect compared to placebo.
