Methods: Lateral cephalograms of 30 adult patients with anterior open bite treated using Invisalign (22 females, 8 males; mean age at start of treatment: 28 years and 10 months; mean anterior open bite at start of treatment: 1.8 mm) were analyzed. Pre- and post-treatment cephalograms were traced to compare the following vertical measurements: SN to maxillary occlusal plane (SN-MxOP), SN to mandibular occlusal plane (SN-MnOP), mandibular plane to mandibular occlusal plane (MP-MnOP), SN to mandibular plane (SN-MP), SN to palatal plane (SN-PP), SN to gonion-gnathion plane (SN-GoGn), upper 1 tip to palatal plane (U1-PP), lower 1 tip to mandibular plane (L1-MP), mesiobuccal cusp of upper 6 to palatal plane (U6-PP), mesiobuccal cusp of lower 6 ...

The well known analytical standards orchard leaves and Bowen's kale have been compared and the value 0.164 ± 0.013 p.p.m. found for the level of mercury in Bowen's kale. Hence, the likely accuracy is ± 8% when matrices similar to Bowen's kale are analysed for mercury by the method described. All factors affecting the precision are discussed. Powdered hair and the standards were shown to be easily homogenisable; however, beard shavings were found to be generally inhomogeneous with respect to mercury distribution, especially when the mercury content was much in excess of ca. 2 p.p.m. owing to exposure of subjects to mercury in the professional working environment. The beard shavings of non-occupationally exposed human beings contained 0.1–1.5 p.p.m. of mercury. Difficulties with the establishment of a mercury mass standard for use with the method are discussed.

Sixty-five first year students from a university in Northern Taiwan participated in a comparative experiment. They were divided into 1) a control group (CT), receiving implicit treatment with no particular rules explained, apart from Chinese translation, and 2) an experimental group, receiving explicit Cognitive Instruction (CI). Each group was treated with four sessions (30 minutes/session) of respective instruction, and a pre-test prior to and two post tests (one post-test and one delayed post-test) after the treatment were administered to gauge participants’ performance. Results indicate that the CI group made significant improvements in both short-term and long-term recall, while the CT in short-term recall only. The findings support that CI instruction of vocabulary and grammar is beneficial, and even necessary, to some aspects of E...
