Anterior composite resins and veneers: treatment planning, preparation, and finishing.

Today's esthetic dental restorations are limited only by the practitioner's artistic ability and imagination. Less invasive procedures such as bleaching, bonding, and veneer placement are useful adjuncts and economic alternatives to more extensive procedures such as crown placement, orthodontic treatment, and orthognathic surgery. In addition to a discussion of the considerations when planning esthetic restorative treatment, technique and material selection, tooth preparation, material placement, and finishing are presented.

Evaluation of orthodontic treatment using the Dental Aesthetic Index.

This investigation evaluates dental esthetic differences of orthodontic patients before and after treatment. The orthodontic treatment provided for patients in this investigation involved the use of removable appliances in 85% of the cases, use of fixed appliances in 2% of the cases, and a combination of fixed and removable appliances in 13% of the cases. Records of patients treated at a dental school clinic between 1959 and 1984 were reviewed. Inclusion criteria for this study included complete patient records, and the presence of dental casts for estimation of the Dental Aesthetic Index (DAI). Of the 932 patients, 116 patient records were included. Fifty patients began treatment during the mixed dentition (age < or = 144 months), and 66 were treated during the permanent dentition (age > 144 months). Pretreatment DAI values and component factors were measured and compared with posttreatment values. The DAI scores improved significantly (p < or = 0.0001) in both age groups (paired t test; Bonferroni correction). However, 20% of the patients showed a worsening or no change in the DAI with treatment. In the mixed dentition group, maxillary anterior irregularities, diastema, and overjet showed statistically significant improvement after treatment (p < or = 0.0001). Patients in the permanent dentition showed statistically significant improvement in the crowding of lower incisors, maxillary anterior alignment, and overjet (p < or = 0.0001). Logistic regression analysis defined five statistically significant factors (p < or = 0.05) that could differentiate patients with successful and unsuccessful treatment outcomes.(ABSTRACT TRUNCATED AT 250 WORDS)

A social perspective on need and demand for orthodontic treatment.

In addition to needs fostered by actual physical disabilities resulting from malocclusion, need and demand for orthodontic treatment may develop entirely apart from any consideration of health needs. In fact, improvement of physical function is not the primary motivation of many persons who receive orthodontic care. A variety of social factors are related to perceived needs for acceptable dentofacial appearance and to public demand for orthodontic services. Since early times human teeth have been the object of mutilations to satisfy sociocultural expectations. The mutilation, and even removal of teeth, to achieve dental cultural norms in, so-called, primitive societies may appear barbaric to an ethnocentric society. However, a significant sociocultural need can be met equally by the African or Brazilian who has had teeth filed to a point and by the Western adolescent who having had four teeth surgically removed to provide space in the arch then undergoes two years of orthodontic therapy to reposition and straighten the remaining teeth. From a sociological point of view, the need and desire of members of a society to achieve a culturally acceptable body image constitutes neither frivolity nor luxury. If children's teeth do not naturally meet the norm for esthetic dental appearance, the response of families to sociocultural expectations and pressures produces a culturally valid need for orthodontic intervention. Other social factors affecting perceived need and demand for orthodontic care are socioeconomic, desire for upward social mobility, and social change with regard to public attitudes toward the availability of dental health services and the increasing removal of financial barriers. Potential changes in present US orthodontic practice may be required if care is to be delivered to significantly larger segments of the population.

Advanced instant photography.

With the popularization of cosmetic and esthetic dental procedures, the importance of various photographic techniques has increased. The dentist's choice of a particular system depends on whether the intended use of the dental image is to assist in treatment acceptance, or to use the patient's "initial phase of excitement" to contribute to photomarketing. This paper uses before-and-after photos to demonstrate a dramatic alteration of the patient's smile. Photomarketing may be enhanced through the introduction of instant cameras, including the Polaroid Macro 5 SLR.

Computer imaging versus conventional esthetic consultation: a prospective clinical study.

Computer imaging can be helpful in demonstrating to patients the potential outcome of esthetic dental procedures. The current clinical study assesses the effectiveness of computer imaging by comparing the reactions of patient and dentist to conventional consultations versus the use of computer imaging. The responses from 35 subjects show that computer imaging consultations are more effective in helping patients decide to accept treatment. Patient satisfaction was higher (93.75%) with computer consultations than with conventional methods (83.3%). Computer imaging consultations were easier to conduct but significantly (p < .05) more time consuming.

Regenerative periodontal therapy in mucogingival surgery for root coverage.

This article illustrates the potential benefits of regenerative periodontal therapy in mucogingival surgery and esthetic dental treatment. Cases are described in which the treatment of soft-tissue recessions and root exposures are treated with surgical procedures where both clinical soft-tissue augmentation and the regeneration of periodontal attachment are obtained. Cases are also presented to illustrate the clinical application of guided tissue regeneration. Resorbable and nonresorbable barriers are placed over the root surface and bone and covered by the overlying flap, which allows the selective repopulation of the lesion by progenitor cells and the inhibition of a long junctional epithelium. Emphasis is placed on regenerative procedures in soft-tissue augmentation, particularly with respect to rationales, techniques, and indications.

Geometric and mathematical proportions and their relations to maxillary anterior teeth.

AIM: One of the critical aspects of esthetic dentistry is creating geometric or mathematical proportions to relate the successive widths of the anterior teeth. The golden proportion, the recurring esthetic dental (RED) proportion, and the golden percentage are theories introduced in this field. The aim of this study was to investigate the existence of the golden proportion, RED proportion, and the golden percentage between the widths of the maxillary anterior teeth in individuals with natural dentition. METHODS AND MATERIALS: Standardized frontal images of 376 dental student smiles were captured. The images were transferred to a personal computer, the widths of the maxillary anterior teeth were measured, and calculations were made according to each of the above mentioned theories. The data were statistically analyzed using paired student T-test (level of significance P<0.05). RESULTS: The golden proportion was found to be accurate between the width of the right central and lateral incisors in 31.3% of men and 27.1% of women. The values of the RED proportion were not constant, and the farther the one moves distally from the midline the higher the values. Furthermore, the results revealed the golden percentage was rather constant in terms of relative tooth width. The width of the central incisor represents 23%, the lateral incisor 15%, and the canine 12% of the width of the six maxillary anterior teeth as viewed from the front. CONCLUSIONS: Both the golden proportion and the RED proportion are unsuitable methods to relate the successive widths of the maxillary anterior teeth. However, the golden percentage theory seems to be applicable to relate the successive widths of the maxillary anterior teeth if percentages are adjusted taking into consideration the ethnicity of the population.

Conservative adjunct to esthetic orthodontic treatment in young patients.

The esthetic effect of orthodontic treatment in young patients may sometimes be incomplete without performing additional procedures related to the form and texture of the anterior teeth. Six young patients, aged 7 to 21 years, presented for orthodontic treatment to improve their dental esthetics. The problems of tooth staining, mutilation, congenitally missing teeth, tooth size/arch length discrepancy, and sequellae of dental trauma neccessitated a combined orthodontic-prosthodontic treatment. Changing morphology and texture by conservative prosthetic procedures proved to be a successful complement to orthodontic treatment.

Nonsurgical correction of an adult skeletal class III and open-bite malocclusion.

This case report presents an adult skeletal Class III and open-bite malocclusion case treated without surgical intervention using fixed edgewise technique, reverse headgear, and Class III and anterior box elastics. The patient was a 16-year-old Turkish female who had completed her growth and development. She had a four mm open bite, maxillary retrognathia, a crossbite in the anterior and left posterior, and hypoplasia of the maxillary laterals. In addition, the patient's first molars had previously been extracted because of caries, and extraction spaces were present. We applied a Roth edgewise appliance and a reverse headgear to be used at night only for the first six months. The objective in using a reverse headgear was to displace the maxillary teeth toward the mesial and to rotate the maxilla in a clockwise direction. In the mandible, we retracted the mandibular incisors and canine teeth and moved the second molars mesially toward the first molar extraction space. There would thus be no need for any prosthetic restoration in the mandible. At the end of treatment, we obtained a Class I dental relationship, an ideal occlusion relationship, and an esthetic dental and facial relationship. Treatment of the patient was completed in 20 months.

Socio-economic risk indicators for apical periodontitis.

OBJECTIVE: The aim of this study was to reveal possible socio-economic risk indicators for apical periodontitis. MATERIAL AND METHODS: In 1992-93 a representative sample of women in Göteborg, Sweden, aged 38-84 years, participated in a medical and dental survey (n=981) which included dental and medical examinations and dental radiographic examination (OP). The dependent variable was apical periodontitis (AP=0, AP>0). The independent variables were age, number of teeth, number of restored teeth, number of root-filled teeth, number of teeth with carious lesions, satisfactory masticatory function, and dental esthetics as crude measures of self-reported dental health, dental anxiety, time elapsed since last visit to a dental office, regular dental visiting habits, smoking, alcohol habits, and marital status. A subjective evaluation of economy, health and life situation (acceptable or poor) was accounted for as socio-economic variables. The oldest age group, women born 1908, and edentulous individuals were omitted, leaving 844 subjects for analysis. Statistical analysis included multivariate logistic regression, chi-squared test, and independent t-test for comparison of group characteristics (AP=0 vs AP>0). RESULTS: For socio-economic variables there was a significant association between acceptable health and apical periodontitis (OR=1.72 (CI=1.09-2.70)). For oral-related variables, root-filled teeth (OR=1.17 (CI=1.10-1.23)) and teeth with carious lesions (OR=1.48 (CI=1.19-1.85)) were predictive of apical periodontitis. CONCLUSIONS: In the present study, socio-economic variables and dental visiting habits did not appear to have obvious implications for periapical health, whereas root-filled teeth and carious lesions were associated with apical periodontitis.

Porcelain laminate veneers and the single-tooth implant: a combination treatment alternative.

The development of implants that are predictable and successful long-term replacements for missing teeth (as a result of disease or trauma) in both full and partially edentulous situations has led to their acceptance as part of mainstream restorative dental therapy. In partially edentulous cases, implants can be combined with various esthetic dental restorations. This article will describe a case in which optimum anterior esthetics were obtained using a combination of single-tooth implants and porcelain laminate veneers.

[Dental trauma: coronal fractures of permanent incisors. A new technique of bonding fragments].

The coronal fractures of the upper incisors for traumatic injuries represent the 8% of the total dental trauma. The use of new dentinal adhesive have permitted to obtain new interesting development in dental traumatology and dental esthetic, like the possibility of the utilisation of the dental fragment, of the incisor broken for a trauma. The new dentinal adhesive is the Gluma (Bayer). The Authors describe the technique, the times, some particulars and step by step all the method to obtain good final results. Finally are presented all the advantages compared to the traditional methods with the composites materials.
