“… 18 In previous studies, it has been reported that Class II malocclusion is closely associated with the severity of OSA, which could be attributed to a backward positioning of the tongue in such patients. 20 , 30 This finding was in disagreement with the outcome of the present study, as the severity of OSA did not have any association with class II molar or canine occlusion. This difference could be due to issues related to ethnicity, as some racial groups present predominantly with Class I malocclusion in OSA conditions.…”

Objectives:To evaluate characteristics of dental occlusion among non-obese Saudi adult patients suffering from moderate to severe obstructive sleep apnea(OSA).Methods:Following ethical approval, a cross-sectional study was conducted at Sleep Disorders Center, King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia, between January and March 2017. Non-obese adult Saudi patients with moderate/severe OSA (apnea-hypopnea index>15) and without history of malocclusion or edentulism were included with an estimated sample size of 50. Demographic details and severity of OSA as diagnosed by polysomnography were recorded. Characteristics of dental occlusion, namely molar, canine and incisor relationship, overjet, overbite, crossbite and arch form were obtained through calibrated examiners (kappa 0.81). Descriptive statistical analysis and Chi-square test, with 95% significance level (p<0.05), were used to identify relationships between the severity of OSA and characteristics of dental occlusion.Results:A total of 51 patients (31 males, 20 females; mean age 49.45±10.35 years), were enrolled in the study. Severity of OSA was moderate in 17 patients and severe in 34 patients. Severe form of OSA was more among males (64.7%) and in patients with Class-II division-1 incisor relationship (94.1%). Neither the demographic characteristics, nor characteristics of dental occlusion showed statistically significant relationship with the severity of OSA.Conclusion:The results of the present cross-sectional study indicate that the characteristics of dental occlusion are not related to the severity of OSA among non-obese adult Saudi patients.

“…The study [ 46 ] showed that the forward head posture associated with scoliosis may lead to stretching of the muscles, skin, and fascia covering the head and neck, impeding the sagittal growth of the mandible and facial skeleton, which leads to class II malocclusion. Besides, class II malocclusion has been reported as a dental feature associated with obstructive sleep apnea which could explain sleeping disturbances in IS patients [ 47 ]. The stud y[ 48 ] suggested that sleep screening should be taken into consideration for the evaluation and treatment of patients with early-onset scoliosis, because poor-quality and inadequate sleep has a bad influence on children’ behavior, cognitive function, and growth.…”

Background Idiopathic scoliosis (IS) affects patients’ quality of life, yet there have been few reports of its morphology and epidemiological study in the southeast region of China. The aim of this study is to access the curve characteristics, prevalence, and factors associated with IS in Chaozhou city. Methods A cross-sectional study was performed in 2018, in which scoliosis screening was conducted among 5497 primary school students in Chaozhou city. Then, a case-control study based on the screening involving 2547 children was followed for the exploration of the associated factors. The questionnaires covering demographic characteristics, postural habits, cognition and self-sensation of scoliosis, and physical conditions were addressed for the investigation. ORs with 95%CIs were calculated based on logistic regression analysis to evaluate the factors associated with scoliosis. Results The prevalence of IS among primary school students was 6.15% in Chaozhou city, with 4.04% for males and 8.71% for females. The average Cobb angle was 15° (range 8 to 37°). Multiple logistic regression analysis suggested that female (OR=2.45), BMI (OR=0.67), having myopia (OR=1.49), self-sensation of scoliosis with symptoms (OR=5.52), insufficient sleep time (OR=2.65, 3.33), and less exercise time (OR=7.09, 7.29) were significantly associated with IS. Conclusions The prevalence of IS among primary school students in Chaozhou was at an average level, and it was significantly higher in females than in males. Lower body mass, having myopia, insufficient sleep time, and lower physical activity were associated with IS.

“…Since 1975, sleep apneas have been identified as the major cause of rapid infant death syndrome [12]. Risk factors like asthma, cigarette smoke exposure and aberrant craniofacial forms are potential contributing factors for children [13,14], in which malocclusion plays a major role [15]. Upper airway, craniofacial morphology and OSA are closely inter-related [16].…”

Background. Obstructive sleep apnea (OSA) is a condition that affects a patient’s ability to sleep normally, predisposing them to many risks and reduced quality of life. Myofunctional therapy has been proven to increase the airway space according to literature. Aim. To report the effects of AdvanSync2 Class II corrector in the management of 3 orthodontic patients who reported sleeping difficulties due to breathing problems and retrognathic mandible. Case presentation. Three patients reported to Department of Orthodontics and Dentofacial Orthopaedics with Class II malocclusion associated with sleep apnea requiring treatment. Clinical examination revealed a retrognathic mandible with airway constriction in all subjects. A non-extraction approach using an AdvanSync2 Class II corrector (Ormco Corp, Glendora, Calif) with fixed appliances was considered. Lateral cephalometric records were obtained at three stages: pre-treatment, post functional and prefinishing/post treatment. The airway was divided into 3 parts in the lateral cephalogram: velopharynx, hypopharynx and glossopharynx. The most constricted part of the airway was noted. Pre and post treatment lateral cephalograms were compared to assess the changes in airway dimensions after using AdvanSync2. Significant enhancement in airway dimensions was noted in all three parts (velopharynx, glossopharynx and hypopharynx) in all patients. Conclusion. Airway assessment is an important aspect in orthodontic diagnosis. Use of the AdvanSync2 Class II corrector in combination with fixed orthodontic appliances enhanced quality of life in Class II patients by improving airway dimensions. This approach can be recommended in the management of mild to moderate Class II malocclusions associated with mandibular retrognathism and airway constriction.
