Repair or replacement of amalgam restorations: decisions at a USA and a UK dental school.

Whereas replacement of failed restorations is the major treatment for adults in dental practice, repair is an important alternative with the potential to save tooth structure and increase the longevity of restorations at a lower cost. This in vitro study recorded the choices of treatment for the same set of teeth with defective Class II amalgam restorations by students and faculty at two dental schools (University of Manchester, UK and University of Florida, USA). Treatment options (monitor, refurbish, repair and replace) and reason(s) for the choice of treatment for 24 marked amalgam restorations were selected. Overall, participants more frequently chose replacement of restorations; whereas, repair was the least favored option. The reasons cited the most to replace restorations were secondary caries including unsightly appearance, partially lost restoration and tooth fracture; for repair, the major reasons included loss of part of the restoration and marginal ditching; and for refurbishment, the major reasons included poor anatomic form and marginal ditching. There was a significant difference between the students and faculties at the two sites in their choice of treatment (p<0.0001; Chi-square test). The treatment decision to "monitor" the restorations was more frequent for the Manchester site than the Florida site. Conversely, the combined treatment decisions to "refurbish, repair and replace" were more frequently chosen in Florida than in Manchester.

Dental aspects of 1248 cases of child maltreatment on file at a major county hospital.

The frequency of head, face, mouth, and neck injuries due to child maltreatment was investigated in a review of 1248 cases on file in the pediatrics office at Hennepin County Medical Center in Minneapolis, Minnesota, from January, 1985, to December, 1989. There were 485 boys (38.8%) and 763 girls (61.2%) examined. Physical abuse cases (41.0%) outnumbered sexual abuse (35.4%) and neglect episodes (23.6%). The gender ratio was distributed equally except in sexual abuse, where there were 4.7 girls for each boy examined. More than half of the children (52.9%) were in the 0-to-4 year age group. Considering all cases together, 37.5% presented with injuries to the head, face, mouth, and neck. However, that percentage doubled (75.5%) when physical abuse episodes were reviewed alone. The intraoral injuries seen were five tooth fractures, three tongue and tongue frenulum lacerations, two lip frenulum lacerations, 11 injuries to the oral mucosa, eight palatal lesions, two fractures of the mandible or maxilla, loose and missing teeth, and dental neglect. Despite the high frequency of injuries, no dentists examined children at the time of the hospital intake or referred children for suspicion of maltreatment in the population studied. The findings suggest the importance of involving dental professionals in identifying, reporting, and preventing child abuse and neglect.

Prophylactic root resection and periapical grafting for anterior implant aethetics: an integration of tissue-reconstruction and tissue-preservation concepts.

The presence of active infections involving the labial bony plate of a failing maxillary anterior tooth presents a challenging situation for aesthetic implant replacement. Not only would the septic state of an abscess be detrimental for immediate implant placement and bone augmentation, but the accompanying bony destruction would also increase the likelihood and magnitude of gingival recession, making this a bioaesthetic challenge. This article describes a technique that integrates tissue-reconstruction and tissue-preservation concepts to achieve peri-implant tissue aesthetics as well as its clinical rationale.

Five factors to be considered when restoring endodontically treated teeth.

UNLABELLED: Maintenance of tooth integrity and strength is critical to the longevity of any restoration. Endodontic treatment inherently requires reduction of supportive tooth structure to provide access and shape and clean the root canal system. Restorative modalities following root canal therapy must provide sufficient strength for the prosthetic material and tooth structures. This article presents several considerations in the treatment of endodontically compromised teeth to ensure clinical success. LEARNING OBJECTIVES: This article discusses relevant considerations in the restoration of endodontically treated teeth. Upon reading this article, the reader should: Understand the factors that affect the strength of an endodontically treated tooth. Recognize the available restorative options following root canal therapy.

[Emergency signs in oro-facial traumatology in children and adolescents].

Based on an analysis of the literature concerning the children and adolescents with dental trauma to primary and permanent teeth, the treatment is multidisciplinary, requiring surgical, orthodontic, operative and prosthetic compliance. Periodic check-up is essential. These guidelines are intended as an aid to the dentist in the management and treatment of traumatized teeth and should be revised as soon as more evidence about the effect of treatment delay becomes available.

Supernumerary premolars associated with dens evaginatus: report of 2 cases.

Dens evaginatus is a dental anomaly found predominantly in people of Mongoloid origin. Dentists practising in Western countries should also be aware of this condition because of the increasing migration of people from Asia. Supernumerary premolars are uncommon but may be found incidentally during radiographic examination of teeth with dens evaginatus. This article reports 2 cases of concomitant occurrence of supernumerary premolars and dens evaginatus. The presence of a supernumerary premolar in 1 quadrant is an indication for radiographic examination of all other premolar regions.

Immediate esthetic management of a catastrophically fractured anterior.

A quick, failsafe method for the esthetic replacement of a catastrophically fractured anterior tooth was presented. This method required minimal armamentarium and no anesthesia. In addition, it employed a technique that is not technique sensitive. The patient and the dental team both benefit by resolving the esthetic crisis using simple methods and excellent time resource management.

A three year follow-up of posterior doxadent restorations.

A new direct restorative material, a calcium aluminate cement, was introduced in the year 2000 and sold under the name Doxadent (Doxa AB, Uppsala, Sweden). The aim of this study was to evaluate Doxadent used in class I and II cavities. A total of 63 restorations were evaluated clinically, according to sligthly modified USPHS criteria, at baseline, after 6 mths, 1, 2 and 3 yrs. Four of the patients reported post-operative sensitivity. At 3 yrs, 62 restorations were evaluated. At 6 mths 9.5% non-acceptable Doxadent restorations were observed, 17.5% at 12 mths, 24.2% at 2 yrs and 21% at 3 yrs, which resulted in a cumulative failure frequency of 72.6% at the end of the 3-years for the new restorative material. Main reasons for failure were material or tooth fracture. It can be concluded that Doxadent showed a non-acceptable clinical failure rate as a posterior restorative, especially in class II cavities.

Reconstruction of devital teeth using direct fiber-reinforced composite resins: a case report.

Nonrestored devitalized teeth are structurally compromised and represent one of the greatest challenges for the clinician. Restoration of endodontically treated teeth has been associated with the use of posts. Various post materials and designs have been introduced over the years; however, motivated by the desire to conserve the remaining sound tooth structure and thanks to properties of modern adhesive systems, clinicians have re-evaluated the dogma of traditional restorative dentistry and seek alternative methods to build up devitalized teeth. The use of direct Ultra High Molecular Weight Polyethylene (UHMWPE) fiber-reinforced post systems is becoming popular among clinicians because enlargement of the root canal space is not required and the risk of root perforation eliminated. This article presents an experimental clinical technique to reconstruct severely damaged endodontically treated posterior teeth using direct fiber reinforced post systems. Particular attention is paid to the incremental and curing techniques adopted to build up the restoration. The problems that clinicians can encounter in bonding to teeth that have undergone endodontic treatment are also analyzed. Questions that have yet to be answered by scientific research are presented.
