Effects of rapid maxillary expansion on upper airway parameters in OSA children with maxillary restriction: A CBCT study.

Background: Rapid maxillary expansion (RME) has been proposed as an effective treatment for pediatric obstructive sleep apnea (OSA) and maxillary restriction in children. This study aimed to evaluate the effect of RME appliances on the nasomaxillary complex dimensions in children with OSA and maxillary constriction.

Methods: This prospective longitudinal study included 34 children aged 8-12 years with maxillary restriction and OSA confirmed by polysomnography who had completed RME therapy.

Dental Arch Relationships of Saudi Children with Unilateral Cleft Lip and Palate.

Aim: To determine dental arch relationships of Saudi children born with nonsyndromic complete unilateral cleft lip and palate (UCLP).

Material And Methods: This is a retrospective cohort study that comprised dental study models of 74 UCLP Saudi children aged 8-10 years who were recruited from 14 referral cleft centers. All participants had their cleft lip and palate repaired with no history of alveolar bone graft or any orthodontic treatment.

Effects of twin-block appliance on upper airway parameters in OSA children with class II malocclusion and mandibular retrognathia: a CBCT study.

Unlabelled: Twin-block appliance had been advocated as a potential treatment option in paediatric obstructive sleep apnoea (OSA) due to their favourable effect in enhancing upper airway parameters and improving OSA symptoms. The aim of this study was to evaluate the effect of twin-block appliance therapy on upper airway parameters/dimensions and the apnoea-hypopnea indexes (AHIs) in OSA children with class II mandibular retrognathic skeletal malocclusion using cone-beam computed tomography. This prospective longitudinal study comprised 34 polysomnography-proven OSA growing children with class II mandibular retrognathic skeletal malocclusion between the ages of 8 and 12 years who had completed myofunctional twin-block therapy and matched corresponding controls.

Three-dimensional analysis of upper airways in Class II malocclusion children with obstructive sleep apnea.

Background: Morphometric evaluation of upper airways helps in identifying potential craniofacial anatomy that may predispose to pediatric obstructive sleep apnea (OSA). This study evaluated upper airway parameters three-dimensionally in children with OSA, with Class II malocclusion and a retrognathic mandible, to identify cutoff values for cone-beam computed tomography measurements that may predict the presence and severity of pediatric OSA.

Methods: The study comprised 47 growing children with OSA with Class II malocclusion and 47 low-risk OSA-matched controls.

Tonsil Size and Mallampati Score as Clinical Predictive Factors for Obstructive Sleep Apnea Severity in Children.

Aim And Objective: The aim of this study was to determine the clinical utility of body mass index (BMI), tonsil size, and Mallampati scoring in predicting both the presence of and severity of pediatric obstructive sleep apnea (OSA).

Materials And Methods: This prospective cross-sectional study comprised 78 growing children in the age range of 11-14 years with polysomnography (PSG)-proven OSA and 86 non-OSA corresponding controls. BMI, tonsil size (Friedman grading scale), and Mallampati score were determined for both groups, and related differences were assessed with a -test, while their independent association with OSA severity was tested with a regression analysis.

Prevalence of Sleep-disordered Breathing and its Association with Obesity among Saudi Schoolchildren.

Aim And Objective: Epidemiological studies of sleep disturbances are essential to promote awareness among families and educational officials and deliver appropriate treatment at a very early timing. The aim of this population-based study was to determine the frequency of sleep-disordered breathing (SDB) symptoms and its association with obesity among schoolchildren in West Saudi Arabia.

Materials And Methods: This cross-sectional study comprised 2,000 schoolchildren aged 6-12 years.

A CAD/CAM Zirconium Bar as a Bonded Mandibular Fixed Retainer: A Novel Approach with Two-Year Follow-Up.

Stainless steel alloys containing 8% to 12% nickel and 17% to 22% chromium are generally used in orthodontic appliances. A major concern has been the performance of alloys in the environment in which they are intended to function in the oral cavity. Biodegradation and metal release increase the risk of hypersensitivity and cytotoxicity.

Orthodontic treatment need and demand among 12- and 16 year-old school children in Malaysia.

Background Of The Study: Assessment of orthodontic treatment need and demand helps in planning orthodontic services and estimating the required resources and man power. The aim of this study was to assess the orthodontic treatment need and demand and to assess the association between the orthodontic treatment demand and factors such as ITON, gender, and age.

Materials And Methods: Treatment need was assessed using the DHC and AC of IOTN among 12- and 16-year-old Malay school children.

Dentoalveolar relationships of Malay children with unilateral cleft lip and palate.

Objective: To determine the treatment outcome based on dentoalveolar relationships among Malay children born with nonsyndromic complete unilateral cleft lip and palate (UCLP).

Design: Retrospective cohort study.

Setting And Sample Population: The Department of Orthodontics at the School of Dental Science and the Reconstructive Sciences Unit, School of Medical Science, Universiti Sains Malaysia.
