摘要:

summaryAn epidemiological study was conducted on 386 children aged 6–10, with and without unpleasant life events, to investigate the synergistic effect of malocclusion and oral parafunctions on cranio mandibular dysfunction. The results showed that the synergistic effect of certain occlusal factors and oral parafunctions was significantly correlated with clicking and symptoms of dysfunction in both groups and with TMJ and muscle tenderness in subjects without npleasant life events. In children with unpleasant life vents TMJ and muscle tenderness were not correlated with any combination of malocclusion and oral parafunction. The present study suggests that the synergistic effect of malocclusion and oral parafunctions is a ‘sufficient’ cause for development of clicking and symptoms of dysfunction in both groups and TMJ and muscle tenderness in subjects without unpleasant life events. Also, in children with unpleasant life events, other aetiologic factor(s) can be responsible for the development of TMJ and muscle tende

摘要:

summaryThe purpose of thisin vitrostudy was to evalu ate the microleakage of direct and indirect inlay/onlay systems. Two of the groups investigated have indirect applications only and consist of microfine composites. The other two groups of inlay/onlay systems have both direct and indirect applications and are hybrid compos ites. Standardized MOD preparations were cut in 60 extracted human premolars. One gingival margin was placed in enamel above the cementoenamel junction (CEJ) and the other was placed in dentine below the CEJ. The inlays were made and luted according to each manufacturer's recommendation. The restored teeth were thermocycled and immersed in a basic fuchsin solution for 24 h. Following the mesiodistal sectioning of the specimens, extent of dye penetration at the restoration‐glass ionomer cement and tooth‐glass ionomer cement interfaces were scored using a stereomicroscope. Both direct and indirect inlays showed substantial leakage at gingival‐dentine mar gins. However, there was only superficial leakage at enamel margins. Comparing the overall indirect inlay systems, EOS inlay leaked the most (P≤0.05). Indirect Brilliant Dentin®inlays showed a significantly smaller amount of leakage than the other inlay systems. SR‐ Isosit®and Estilux Posterior C VS®inlays provided a favourable marginal seal. In the case of Brilliant Dentin®and Estilux Posterior C VS®, indirect inlays leaked more than direct inlays. Generally, no significant difference was observed between the interfaces evaluated in microleaka

摘要:

summaryObstructive sleep apnoea may present with a wide range of symptoms resulting in a variety of referral pathways. A multidisciplinary approach to examination and diagnosis helps to determine the most appropriate treatment plan for each individual. The subject is seen by each member of the team, appropriate investigations undertaken and a further meeting arranged at which all opinions are discussed. A reasoned treatment regime is produced, taking into consideration the patient's wishes and overall medical condition. This paper describes the team approach currently employed in the Department of Thoracic Medicine at The Prince Charles Hospital, Brisbane, Australia. The thoracic physician and ENT surgeon work in close collaboration with their dental colleagues: an orthodontist, prosthodontist and a maxillofacial surgeon. An outline of the examination and investigations made by each is described and the multidisciplinary approach is illustrated by a des cription of the management of five subjects with suspected obstructive sleep apnoea.
