The present work was an attempt to investigate for the existence of an association between anxiety psychopathology and bruxism. The presence of bruxism was investigated according to validated clinical criteria in 98 subjects, who also filled out a self-report questionnaire (PAS-SR) for the assessment of panic-agoraphobic spectrum. 34.7% (n = 34) of participants were diagnosed as bruxers. The prevalence of anxiety psychopathology was similar between bruxers and non-bruxers, but Mann-Whitney U-test revealed significant differences in total PAS-SR (P = 0.026) score, indicating that subclinical symptoms of the anxiety spectrum might differentiate bruxers from controls. In particular, significant differences emerged in scores of domains evaluating panic (P = 0.039), stress sensitivity (P = 0.006) and reassurance sensitivity symptoms (P = 0.005) of panic-agoraphobic spectrum. Support to the existence of an association between bruxism and certain psychopathological symptoms has been provided.
These results reveal a reasonable degree of cross-cultural consistency between the two versions of the OHIP, and thus indicate that our Italian version is valid.
The quality of the available literature is not adequate to provide an evidence base on the topic. Despite the heterogeneity of design and findings of the reviewed articles, it seems reasonable to suggest that skeletal Class II profiles and hyperdivergent growth patterns are likely associated with an increased frequency of TMJ disc displacement and degenerative disorders.
SummaryBackground. The aim of the present article is to present a set of proposed clinical recommendations aimed at Italian dentists involved in the management of patients with obstructive sleep apnea syndrome or snoring. Methods. With the purpose of creating a study group, some of the most important Italian scientific societies operating in fields relevant to the issue of sleep medicine in dentistry were asked to appoint a representative. Each member of the study group was required to answer questions regarding the clinical management of OSAS and snoring. Results. Oral appliances can be used to treat: -simple snoring, in patients who do not respond to, or do not appear to be suitable candidates for behavioral measures such as weight loss or positional therapy;
Oral appliances (OAs) of various types have shown variable success in the treatment of mild-to-moderate obstructive sleep apnoea (OSA). In an OSA sample, this study evaluated the efficacy of a diagnostic trial OA (myTAP™); the efficacy of a definitive custom-fitted mandibular advancement device (MAD) (SomnoDent Flex™); and whether a trial device can be used to distinguish treatment responder from nonresponder patients. Patients underwent overnight home sleep recordings prior to and after fitting of these appliances in order to objectively assess their sleep quality in terms of polysomnographic (PSG) respiratory measures: apnoea-hypopnoea index (AHI), oxygen desaturation index (ODI), and minimum oxygen saturation (LowSpO2). 40 patients with symptomatic OSAS were enrolled, 33 males and 7 females, with a mean age of 55.6 ± 12.73 years and an initial (T0) AHI of 26.51 ± 14.79. Trial devices were used in 16 patients (AHI: 29.9 ± 19.97, ODI: 21.06 ± 16.05, and LowSpO2: 82 ± 10.22 at T0) and definitive MADs in 28 (AHI: 23.90 ± 9.19, ODI: 16.27 ± 11.34, and LowSpO2: 82.87 ± 6.04 at T0). Statistically significant decreases in AHI (9.59 ± 8.94,
p
<
0.0023
) and ODI (8.20 ± 9.67,
p
<
0.0129
) were observed after treatment with the trial device. Only 8 of the patients in the trial device group went on to use the definitive device. Treatment with the definitive MAD produced statistically significant decreases in AHI (11.46 ± 9.65,
p
<
0.0001
) and ODI (9.10 ± 8.47,
p
<
0.0016
) and a significant improvement in LowSpO2 (85.09 ± 6.86,
p
<
0.0004
). Thus, both types of device proved effective in improving the PSG parameters. This study showed that introducing an easy-to-make and low-cost trial device into the therapeutic pathway of OSAS patients can circumvent the problem of individual responses to treatment by allowing effective classification of patients: in short, it allows a first distinction to be drawn between responders and nonresponders to treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
