Weight gain may affect mandibular advancement device therapy in patients with obstructive sleep apnea: a retrospective study.

PURPOSE: The aim was to analyze whether or not weight gain influences the treatment outcome of patients with obstructive sleep apnea (OSA) treated with mandibular advancement devices (MAD). METHODS: As a part of a follow-up study among OSA patients treated with MAD in primary oral health care, a group of 28 patients reporting worsening of daytime or nighttime symptoms of OSA was given closer examination. Altogether, 21 subjects had a complete set of recordings and were enrolled into the study. RESULTS: Only three subjects had lost weight during the study period. The mean weight gain of 3.6 kg ± 7.1 kg was significant (p = 0.035). According to linear regression, weight gain was independently significantly associated with lower mean peripheral oxygen saturation 92.4 (SD 1.8 (% per hour) (p = 0.019)) and lowest oxygen saturation 80.1 (SD 7.2 (%) (p = 0.024)) scores. CONCLUSIONS: Weight gain is detrimentally associated with MAD treatment in patients with OSA. These findings suggest that regular follow-up by an experienced dentist is advisable to assess for possible worsening of OSA. Patient support to encourage weight control may be an important adjunct to MAD treatment for OSA.

Pain and pain behavior in burning mouth syndrome: a pain diary study.

AIMS: To characterize pain related to primary burning mouth syndrome (BMS) in terms of intensity, interference, and distress caused by the pain, as well as factors influencing the pain across a period of 2 weeks, and to study the use of coping and management strategies on a daily basis. METHODS: Fifty-two female patients with primary BMS completed a 2-week pain diary. Pain intensity, interference, distress, and mood on a 0 to 10 numeric rating scale (NRS), as well as pain amplifying and alleviating factors, were recorded three times a day. The use of treatments (medication or other means) and coping strategies were recorded at the end of each day. Coefficient of variation, repeated measures analysis of variance, and correlative methods were used to assess the between- and within-subject variation, pain patterns, and associations between various pain scores. RESULTS: The overall mean pain intensity score of the 14 diary days was 3.1 (SD: 1.7); there was considerable variation in pain intensity between patients. Most patients experienced intermittent pain. On average, pain intensity increased from the morning to the evening. Intercorrelations between pain intensity, interference, distress, and mood were high, varying between rs = .75 and rs = .93 (P < .001). Pungent or hot food or beverages, stress, and tiredness were the most frequently mentioned pain-amplifying factors. The corresponding pain-alleviating factors were eating, sucking pastilles, drinking cold beverages, and relaxation. Thirty (58%) patients used pain medication and 35% reported using other means to alleviate their BMS pain. There was large variation in the use of coping strategies -between subjects. CONCLUSION: There were considerable differences in pain, in factors influencing the pain, and in pain behavior across BMS patients. This indicates that patient information and education as well as treatment of BMS pain should be individualized.

Mandibular advancement device therapy for obstructive sleep apnea: A longitudinal study among patients treated in community dental care in Finland - Potential for the precision medicine approach.

Objective: Obstructive sleep apnea (OSA) is an increasing health problem worldwide. The aim was to evaluate long-term mandibular advancement device (MAD) therapy outcomes in community dental care among OSA patients in Finland.Methods: In all, 142 (77.2%) respondents of a questionnaire, with recently initiated treatment, were included in the study in 2010. Follow-up questionnaires were mailed in 2012 and 2017.Results: Problems occurred with the device long-term. Orofacial pain was reported more often in 2012 than in 2010 (p < 0.01). Snoring (p < 0.01) and tiredness (p < 0.05) were also significantly increased. In 2017, 50 subjects were still continuing with MAD, 20 of them as a single treatment modality. Treatment modalities in combination with MAD were CPAP, nutrition counseling, and position treatment.Discussion: Long-term MAD treatment may lead to a changing treatment-mix and set-backs. This may not only be a treatment adherence issue but also a lack of precision medicine approach regarding OSA.
