Background: Several studies have reported an association between periodontal disease and obstructive sleep apnea (OSA). However, heterogeneity of results suggests that there is insufficient evidence to support this association.
Aims: The objective of this study was to identify the association between periodontal disease and OSA in adults with different comorbidities.
Settings And Design: One hundred and ninety-nine individuals (107 women and 92 men) underwent polysomnography with a mean age of 49.9 years were recruited.
Materials And Methods: The presence of OSA, comorbidities, and periodontal disease was evaluated in each individual. Student's -tests or Chi-square and ANOVA tests were used to determine the differences between groups.
Results: The prevalence of periodontal disease was 62.3% and 34.1% for gingivitis. The results showed no statistically significant association between all groups of patients with OSA and non-OSA patients for gingivitis ( = 0.27) and for periodontitis ( = 0.312). However, statistically significant association was shown between periodontitis and mild OSA compared with the periodontitis and non-OSA referent ( = 0.041; odds ratio: 1.37 and 95% confidence interval 1.11-2.68). The analysis between OSA and comorbidities showed a statistically significant difference for patients with OSA and hypertension ( < 0.001) and for patients with OSA and hypertensive cardiomyopathy ( < 0.001) compared with healthy individuals. Periodontitis was more likely in men with severe OSA and with any of two comorbidities such as hypertension or hypertensive cardiomyopathy. Women with hypertension or hypertensive cardiomyopathy were more likely to have mild OSA, and these associations were statistically significant ( < 0.05).
Conclusions: This study identified association between periodontitis and mild OSA and this association was more frequent in women with hypertension or hypertensive cardiomyopathy. Periodontitis was associated with severe OSA in men who showed any of two comorbidities such as hypertension or hypertensive cardiomyopathy.

Aim: This study aimed to evaluate and compare the results of combination therapy involving bone grafting and two different resorbable collagen membranes in 1-, 2- and 3-wall infrabony defects.
Methods: A total of 174 patients with infrabony defects (≥ 7 mm periodontal probing depth) were randomized to receive deproteinized bovine bone mineral (DBBM) with either a native porcine non-crosslinked collagen membrane (N-CM, control, n = 87) or a novel porcine crosslinked collagen membrane (C-CM, test, n = 87). Clinical parameters, including periodontal probing depth (PPD), clinical attachment level (CAL), and gingival recession (GR), were recorded at baseline, 12 weeks, and 24 weeks.
Dipyridamole Attenuates Experimental Periodontitis by Regulating M1 Macrophage Polarization via PKA/PKG Pathways.

Hospital of Stomatology, Sun Yat-Sen University, Guangzhou, China.
Aim: Periodontitis is a chronic inflammatory disease initiated by dysbiosis of the local microbial community. As a non-specific phosphodiesterase inhibitor, dipyridamole features anti-oxidant and anti-inflammatory properties. This study aimed to investigate the effects of dipyridamole in an experimental rat model of periodontitis.

Background: The stability of soft and hard tissues surrounding the implant is not only a matter of aesthetics, but also affects the long-term stability of the implant. The present study was to explore the influence of buccal mucosa width/height (W/H) ratio, emergence profile and buccal bone width on peri-implant soft and hard tissue changes in the posterior region.
Methods: Fifty-eight posterior implant restoration cases were recruited in this study.
Prediction of oral diseases in care dependent older people.

Department of Odontology, Faculty of Health and Medical Sciences, University of Copenhagen, Nørre Allé 20, Copenhagen, 2200, Denmark.
Background: A large number of older people depend on others for help with their daily personal care, including oral health care. Nursing home and elder-care staff often face challenges identifying older people, who are exposed to or at an increased risk of oral diseases. Thus, the aim of this study was to identify risk factors that non-dental care staff can use to identify older people at risk of oral diseases and poor oral hygiene.

Department of General and Liberal Studies, School of Basic and Biomedical Sciences, University of Health and Allied Sciences, Ho, Ghana.
Background: There is a paucity of data on oral health problems among the residents of Fanteakwa districts (South and North) in the Eastern region of Ghana. Therefore, this study assessed the prevalence and factors associated with self-reported oral health problems in the Fanteakwa districts of Ghana.
Methods: This community-based cross-sectional study targeted residents of the towns of the Fanteakwa districts, who have not had any dental care visit in the past six months preceding the study.
