摘要:

AbstractGuidelines for the successful use of resin bonded bridges are presented. The importance of sound case selection cannot be overemphasized. Other factors that influence the clinical success of resin bonded bridges include preparation design, choice of metal, surface preparation of metal, and the need to respect the sensitivity of the etched alloy surface of the Maryland bridge before and at the cementation stage.

摘要:

AbstractFusion of teeth is most commonly reported in the deciduous dentition, particularly in the anterior teeth. Recently, additional cases of fusion have also been reported in the mandibular molars of the permanent dentition, and are not considered uncommon. However, reports of the involvement of maxillary molars appear to be particularly rare in the literature. This case is another example of the quite rare phenomenon of fusion of maxillary third and supernumerary fourth molars.

摘要:

AbstractDacron‐reinforcedSilasticsheets were removed from two patients who had previously undergone surgery for internal derangements of the temporomandibular joint. Excised tissue from around the joints was submitted for histological analysis, revealing a diagnosis of detritus synovitis. The significance of these findings with respect to the insertion of foreign material into the jaw joint is discussed in the light of recent researc

摘要:

AbstractSince 1975, more than 100 000 Indo‐Chinese refugees from Vietnam, Kampuchea, and Laos have been resettled in Australia. This dental survey was undertaken to compare the dental health of 104 Australian‐born and 126 Indo‐Chinese adolescents from a State high school within a high migrant area of Melbourne. The mean DMFT score for the Australian‐born group was 3.37 teeth, compared with 6.05 for the Vietnamese group, and 3.10 for the Kampuchean‐Laotian group. More restorations and extractions were required by the Vietnamese subjects compared with the Australian‐born and Kampuchean‐Laotian subjects. Almost all subjects had gingivitis, however the proportion of Indo‐Chinese subjects with shallow and deep pockets was greater than that of the Australian‐born subjects. The periodontal health of the Kampucheans and Laotians was the most severe of the Indo‐Chinese groups. These findings indicate that the Indo‐Chinese adolescent refugees represent a high risk group for dental problems within the

摘要:

AbstractTwo snack foods marketed specifically for infants were compared in caries prediction tests. A milk powder‐supplemented fruit and cereal snack bar produced more titratable acid but did not reach as low a terminal pH as a sweet biscuit onin vitrofermentation by salivary organisms. In an intra‐oral caries test the fruit/cereal bar caused significantly less enamel softening than the biscuit. While this latter test does not assess food retention in the mouth and other factors important in caries, the results suggest that, under similar usage by children, the fruit bar will be less cariogenic. Because it was not absolutely safe with respect to caries, frequency of eating cannot be disregarded. Availability of the fruit snack bar is an important development, allowing an additional choice for parents who wish to select low‐cariogenicity foods for their chi

摘要:

AbstractGnathosonic recordings are obtained on rapid closure of the teeth to occlusion. A general relationship between gnathosonic tracings and occlusal contact patterns has been demonstrated. Variation of gnathosonic recordings over time for the same individual has not been satisfactorily investigated. The present study suggests that recordings taken at the same sitting are relatively reproducible but reproducibility over time is not high. The series of recordings obtained in this study suggests caution when interpreting a single series of gnathosonic tracings.

摘要:

AbstractA survey of Dental Officers and Dental Therapists in Government Health and Defence Force Clinics throughout Papua New Guinea indicated that the problem of slow setting and even failure to set is a frequent occurrence with composite resin materials. This is because these materials tend to deteriorate at high temperatures to which they may be subjected during transport, initial storage and clinical storage awaiting use.Eight brands of composite resin, including paste‐paste, powder‐liquid and light‐activated systems, as well as three glass ionomer cements were evaluated over a period of twelve months with respect to shelf‐life and suitability for use in a tropical environment. Preliminary results indicated that, although a light‐activated composite resin appeared to be the material of choice, it may not be suitable because it is relatively expensive and requires a curing light which is electrically operated. A powder‐liquid composite resin was, therefore, the recommended product. On the other hand, it was also suggested that a powder‐water glass ionomer cement, Chemfil II, might be a suitable alternative for a developing, tropical country such as Pap
