    Notes: The reading test performances of 60 hearing and 60 hearing-impaired children of similar measured reading ages on the Southgate reading test were analysed. As in an earlier study using the Brimer Wide-span test it was shown that the performances of the two groups were quite different. Deaf children tackled significantly more test items than the hearing and made significantly more errors in achieving similar reading scores.A detailed examination of both correct and incorrect answers showed that the deaf children were not simply providing answers to questions at random. Even where they produced incorrect responses they tended, as a group, to select the same answer. Unlike the hearing group, who did not converge on the same incorrect solution to difficult test items, the deaf were systematic in their choices, indicating that they were using a consistent strategy.A post hoc examination of individual test items indicated that the deaf children were selecting answers on the basis of word associations in each test item. On some items these produced a correct response, on others the same (incorrect) response. The implications of these findings are discussed to argue that reading tests based on hearing norms are of little value in the assessment of reading abilities and reading problems in hearing-impaired children.

    Notes: summary  The purpose of this investigation was to determine whether non-setting calcium hydroxide [Ca (OH)2] cement placed in the root canal system of premolar teeth would affect the subsequent microleakage of a glass–ionomer restoration (GIC). Following selection, 62 human premolar teeth extracted for orthodontic reasons were accessed and root canals prepared according to a standardized procedure. The specimens were then allocated randomly into two major groups each of 30 teeth. Two other teeth were used as a positive and a negative control. The control group was restored with glass–ionomer cement following drying of the canal and placement of a cotton wool pledget. The test group had all canals dressed with non-setting Ca(OH)2 and then was subdivided, one set (n=22) being restored following conditioning of the access cavity margins, the other (n=8) having the margins cleaned with a hand excavator. Samples were assessed for microleakage using a two-point scoring system (leakage or no leakage) in conjunction with a clearing technique using AgNO3. Using Fisher's exact test, a statistically significant difference was found between the control and test groups (P 〈 0·05) but there was no significant difference between the excavated and conditioned cavities (P=0·55). It is concluded that contamination of access cavity margins with Ca(OH)2 during medication of a root canal interferes with the bond of GIC, resulting in increased microleakage in vitro.

    Notes: summary  The aim of this study was to determine the average freeway space of dentate subjects and relate this to recommended ranges for edentulous patients, also to see if any differences were observed between two different methods of measuring freeway space. The freeway space of 72 dentate subjects was measured, first using a Willis gauge, and secondly using a pair of sprung dividers. The intra- and interoperator variability was evaluated as was the reproducibility of the accuracy of both techniques. The mean freeway space using the Willis gauge was 3·3 mm, for both intra and inter operator variability, and with the sprung dividers 3·1 and 2·9 mm, respectively, with no significant difference being seen between any combination of results (P 〉 0·05). Individual measurements within the two measuring methods being assessed showed significant differences (P 〈 0·05). The mean measurements of freeway space in dentate subjects found in this study were within the recommended 2–4 mm range, however, 15% of the subjects in the study had freeway space measurements outside this range. This study would suggest that the range for freeway space measurement could more realistically be 2–7 mm.

    Notes: Two studies of the communication skills of orally educated deaf primary school children are repotted. In the first, a referential communication task with very limited linguistic demands, severely and profoundly deaf children performed as well us a hearing control group. In the second task with a richer linguistic domain. differences m performance were found between deaf children from three schools with different linguistic philosophies, children from the school performing com-parably to hearing children, those from the other two schools slightly worse. It is concluded that deaf children are more able communicators than their grammatical competence suggests.

    Notes: In stage 1 classroom conversations between sixteen teachers and their pre-lingually deaf children were videotaped and analysed to examine both the styles used by teachers in controlling conversation and the functions pursued in dialogue. In stage 2 a sub-sample of four teachers with twenty children of known hearing losses and non-verbal intelligence was analysed in greater detail to examine relationships between these factors, teaching styles and the child's performance in dialogue. The analyses show that deaf children respond in a similar fashion to young hearing children in the way they react to different styles of teacher talk; that teachers differ in the functions they pursue in conversation; and that functions change as a consequence of the child's hearing loss but not mental age. The implications of the findings for linguistic development in pre-lingually deaf children are explored.

    Notes: [Auszug] I have developed a taxonomy for describing the structures of certain types of verbal problems which enables such comparisons and distinctions to be made. I have been dealing with problems of the type: "If Pete is taller than Sam, Sam is taller than Ken, John is taller than Ken, Steve is taller than ...
