The response of 1578 school leavers to a campaign combining commercial, Health Boards' and GDPs' sponsorship in an effort to improve dental attendance.

A dental health promotion campaign was developed by Forth Valley Health Board in conjunction with the Scottish Health Education Group and the Department of Marketing at Strathclyde University. The aim was to encourage dental attendance among early school leavers. The emphasis was on the contribution of dental care to appearance and attractiveness. To highlight the importance of appearance, a major clothing retailer offered discounts on clothes to participants who made a dental visit. The impact of the campaign was evaluated by a questionnaire 3 months after its close. Recall of the campaign was high at 62% and 16% actually initiated a dental visit. However, only 2% claimed that the campaign was their main reason for attending. The project demonstrated the feasibility of collaboration between a commercial company and a health board in a health promotion effort. The results underline the difficulties in initiating a behaviour change, overcoming apathy and modifying the lack of felt need for dental care among the age group concerned. It does, however, suggest that there is potential for a more prolonged marketing effort.

Presenting complaints and findings in a group of patients attending a hypodontia clinic.

A survey is presented of the complaints and findings in a group of 451 patients referred to a multidisciplinary clinic for the management of hypodontia. The most common complaints were missing teeth, spacing in the dental arches, and poor appearance. The majority of patients were referred by their dental practitioners, and more than half were over 12 years old when first seen. Delayed referral can have educational and social consequences. Changing attitudes to dental care and the maintenance of an intact dentition are resulting in hypodontia, particularly in its more severe forms, becoming of increasing concern to children and their parents. The management of this condition is best organised via multidisciplinary specialist clinics.

Clinical decision making--an art or a science? Part I: An introduction.

In order to make the most appropriate decision in a given set of circumstances, an understanding is needed of how people formulate decisions on the basis of their surroundings. Using a case history, this article introduces the factors involved in clinical decision making and highlights the relevance of those factors in the decision making process. These will be discussed in depth in later sections of this series.

Anterior dental aesthetics: dentofacial perspective.

The purpose of this series is to convey the principles governing our aesthetic senses. Usually meaning visual perception, aesthetics is not merely limited to the ocular apparatus. The concept of aesthetics encompasses both the time-arts such as music, theatre, literature and film, as well as space-arts such as paintings, sculpture and architecture.

Aesthetic changes with four anterior units.

Cosmetic dentistry has evolved with the advent of more robust porcelain materials and ever-stronger bonding agents. This series of three articles aims to provide a practical overview of what is now possible both functionally and cosmetically from the preparation of a small number of teeth, through a whole smile, to full mouth rehabilitation. A complete diagnosis is the starting point to planning any cosmetic or functional changes. Guidance is given on the techniques used but adequate training must be considered essential before embarking upon modification in occlusal schemes or even minor adjustments in smile design. Conservative use of porcelain laminate veneers can result in significant aesthetic improvements to a patient's smile and it is not always necessary to prepare all the teeth visible in a smile.

Smile lifts - a functional and aesthetic perspective.

Cosmetic dentistry has evolved with the advent of more robust porcelain materials and ever-stronger bonding agents. This series of three articles aims to provide a practical overview of what is now possible both functionally and cosmetically from the preparation of a small number of teeth, through a whole smile, to full mouth rehabilitation. A complete diagnosis is the starting point to planning any cosmetic or functional changes. Guidance is given on the techniques used but adequate training must be considered essential before embarking upon modification in occlusal schemes or even minor adjustments in smile design. Porcelain laminate veneers have a role in the restoration and rehabilitation of a wearing and functionally compromised dentition.

Case report: Long-term outcome of class II division 1 malocclusion treated with rapid palatal expansion and cervical traction.

A case of a Class II Division 1 malocclusion with reduced transpalatal width and unfavorable axial inclinations of the posterior teeth is reported. Rapid palatal expansion (RPE) was used for maxillary enhancement and molar distalization therapy to correct the anteroposterior dental discrepancy. This case report illustrates the results of the method of treatment used with a long-term (16-year-posttreatment) follow-up.

Orthodontic treatment outcomes in the long term: findings from a longitudinal study of New Zealanders.

The aim of this study was to use a health services research (HSR) approach to examine the longer-term outcomes of orthodontic treatment. Participants in a longstanding population-based New Zealand cohort study (the Dunedin Multidisciplinary Health and Development Study) were allocated to one of four malocclusion severity categories on the basis of orthodontic data collected at age 12. The outcome of that care by age 26 was evaluated using the key indicators of equity (was it fair?); efficacy (did it work?); effectiveness (did it work in the longer term?); and safety (was it associated with a greater subsequent experience of caries, periodontal disease, or tooth loss?). Data were available for 452 Study members, of whom 56.2% were in the minor/none category, 29.0% were in the definite category, 10.2% were in the severe category, and 4.6% were in the handicapping treatment-need category. No clear differences in treatment uptake by socioeconomic status were apparent, and the proportion treated increased across the malocclusion severity categories, as did the proportion that showed an improvement following treatment. By age 26 a difference between those who had and those who had not been treated was evident, with the percentage of those rating their dental appearance as above average increasing with increasing severity of the age-12 orthodontic treatment need. This was also true for the percentage that considered their orthodontic treatment to have been successful. There were no significant differences in caries experience, periodontal disease occurrence, or tooth loss between those who had and had not been treated by age 26. This study has found the equity, efficacy, effectiveness, and safety of orthodontic treatment in the Dunedin cohort to be acceptable.

Comparative evaluation of polishing systems on the surface of three aesthetic materials.

This study compared the efficacy of three different polishing methods on a resin composite, a glass ionomer cement (GIC) and a compomer. Thirty samples of each material were prepared. Ten of them were randomly assigned to one of the three polishing methods. The surface roughness (Ra) of the samples were measured before and after the polishing procedure with a profilometer. There was no statistical difference between the composite and the compomer prior to polishing but statistical difference was found between the GIC and the two other materials. After polishing, the smoothest surfaces were obtained using Sof-Lex discs for the three materials, and the roughest surface, with tungsten carbide burs for the composite and the compomer, and with Enhance kit for the GIC. The composite gave the smoothest surface with the three methods.

Fluoride release from aesthetic dental materials.

The objective of the study was to compare the amounts of fluoride released by two glass-ionomer cements, a resin-modified glass-ionomer cement, a compomer and a fluoride-containing composite into deionized water and artificial saliva. Disc samples of each of the materials were fabricated and placed in either water or artificial saliva. Fluoride analysis of the media was performed periodically over 64 days. The data were analysed to show the rate of fluoride release per cm2 per hour for each material. The results showed that the fluoride release rate for all the materials in both solutions decreased dramatically after 24 h. The release rate in artificial saliva was significantly less than in water (P < 0.001). The resin-modified glass-ionomer cement consistently displayed the highest fluoride release rate per hour into both media.

Colour reproducibility of a photo-activated prosthetic composite with different thicknesses.

This study determined the colour accuracy of a photo-activated prosthetic composite with various thicknesses and shades for the purpose of evaluating the relationship between material thickness variation and colour reproducibility. Four light shades (A1, B1, C1 and D2) and four dark shades (A4, B4, C4 and D4) of a representative photo-activated prosthetic composite (Artglass) for body paste were assessed. The specimens were prepared with thicknesses of 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 mm. The L*a*b* colour parameter of each shade was measured using a dental colorimeter (ShadeEye) connected to a computer. The overall colour accuracy of groups of five specimens was compared by means of analysis of variance (ANOVA) and Scheffe's S multiple range test (P=0;05). In addition, L*a*b* colour difference (Delta E*) values between the 3.0 mm thickness and the other thicknesses were calculated. Three-factor ANOVA revealed that all colour parameters were influenced by the thickness as well as by the shade letter and shade tab (P < 0.05). The L* value consistently decreased for all shades as thickness increased, although there was no obvious correlation between the thickness of the material and either the a* or b* values. Among the Delta E* values, the values between the 2.5 and 3.0 mm thicknesses were the lowest, and values were found to be lower than 2.0 for all shades. The colour accuracy of the photo-activated prosthetic composite was related to the thickness of the material regardless of the shade. For acceptable colour reproducibility, a composite material thickness of at least 2.5 mm was found to be required.

Influence of abutment substrates on the colour of metal-free polymer crowns.

New-generation composite materials have excellent strength and wear resistance, and thus can be used to make metal-free crowns. However, composite materials are translucent, and so when using them to make metal-free crowns, it is necessary to take the effect of the abutments into consideration. In this study, five types of materials including three types of new-generation composite materials, a conventional composite material, and a ceramic material were used to examine the translucency (contrast ratio) of the materials and the effects of the colour of the abutments on the final appearance of metal-free crowns. It was found that the materials varied slightly from one-another in translucency and that it was possible to reproduce the desired colour when gold alloy was used for the background. However, it was difficult to produce an adequate colour match when silver-palladium alloy was used for the background. When a tooth colour material that was darker than the target colour was used for the abutment teeth, some materials could not reproduce the target colour satisfactorily.

Audit of a multidisciplinary approach to the care of children with unilateral and bilateral cleft lip and palate.

Cleft lip and palate affects the child in many ways, particularly appearance, dental arch relationships, growth of the face, and speech development. The key to successful care is management in a multidisciplinary team adhering to a well-designed protocol, and careful audit of results. We present the intermediate outcome audit of 15 patients with complete bilateral and unilateral cleft lip and palate whose condition was managed in a multidisciplinary team according to a strict protocol. We give the results observations of operations of a single surgeon's functional primary surgery over a 6-year period in terms of dental arch relationships, cephalometric analyses, aesthetic assessments, and speech analysis. The results show good early facial growth, with dental arch relationships appropriate for the age and group; we found only minor speech discrepancies, with no patients requiring pharyngoplasty. The results show the importance of multidisciplinary management, the value of keeping to sound surgical protocols, and functional techniques in cleft lip and palate surgery. Our study includes the neglected group of children who have bilateral cleft lip and palate, and it conforms to the style of pan-European projects.
