[Impressions in conservative dentistry].

In conservative dentistry, indirect restorations are rather seldom choosen because direct restorations give relatively good results and fit well to conditions of social dentistry. If an indirect restoration is to be realised, it has to be decided if it will be an inlay, an onlay or a crown and which material will be used. A one step putty wash technique impression is the best for registering inlay-onlay preparations. Most often, preparations are few and grouped and allow the dual arch technique. By this technique, it is possible to register in one time the preparations, the antagonists and their occlusal relation. A complete description of this technique is given in a case report.

Complications of body piercing.

The trend of body piercing at sites other than the earlobe has grown in popularity in the past decade. The tongue, lips, nose, eyebrows, nipples, navel, and genitals may be pierced. Complications of body piercing include local and systemic infections, poor cosmesis, and foreign body rejection. Swelling and tooth fracture are common problems after tongue piercing. Minor infections, allergic contact dermatitis, keloid formation, and traumatic tearing may occur after piercing of the earlobe. "High" ear piercing through the ear cartilage is associated with more serious infections and disfigurement. Fluoroquinolone antibiotics are advised for treatment of auricular perichondritis because of their antipseudomonal activity. Many complications from piercing are body-site-specific or related to the piercing technique used. Navel, nipple, and genital piercings often have prolonged healing times. Family physicians should be prepared to address complications of body piercing and provide accurate information to patients.

Clinical performance of posterior compomer restorations over 4 years.

PURPOSE: To clinically evaluate two polyacid-modified resin composites (Hytac and Dyract AP) for the restoration of posterior teeth over a 4-year period and to investigate accessible margins by light microscopy. METHODS: In a controlled prospective clinical study, 71 cavities (21 occlusal, 41 MO/OD, 9 MOD) in 30 patients were restored with compomers by three dentists. Thirty-eight restorations were placed with the combination OSB/Hytac, the same patients received 33 restorations with Prime&Bond 2.1/Dyract AP. Enamel margins of the cavities were etched with phosphoric acid. At baseline, after 12, 24, and 48 months, the restorations were examined by two independent investigators according to modified USPHS-criteria. Focusing on the 40 restorations available at all recalls, a semi-quantitative margin analysis was carried out at each recall using replicas and light microscopy at x130 magnification. RESULTS: Twenty restorations were not investigated at the 4-year recall (drop-out). After 48 months, 11 restorations (Hytac: n = 8, Dyract AP: n = 3) had to be replaced due to tooth fracture (n = 4), gap formation (n = 5), and adhesive failure (n = 2). Forty restorations were still in function after 4 years (overall failure rate 16%; Hytac: 21%; Dyract: 9%). Between the recalls, statistically significant differences were detected for the criteria marginal integrity (Alpha dropping from 76% at baseline to 32% after 4 years), restoration integrity (Alpha ratings at baseline 99% vs. 40% after 4 years), and occlusion (100% vs. 24%). For the criteria surface roughness (from the 6-month recall) and anatomical shape (after 4 years), a significant difference between the materials was evident in favor of Dyract AP. Except gap-free margins, the predominant criterion in the microscopic analysis at baseline was marginal overhang (24%) and 30% negative step formation after 4 years.

[Assessment of traumatic tooth injuries in the emergency room].

Many patients with facial injuries are first seen by doctors in the emergency room. Injuries affecting teeth and alveolar process are common in children; approximately half of all children have sustained such an injury before adulthood. Dentoalveolar trauma does not pose a significant morbid risk for the trauma patient. However, failure to recognise or obtain appropriate consultation can result in premature tooth or alveolar bone loss, resulting in problematic prosthetic rehabilitation. Emergency room doctors should know the initial treatment guidelines for traumatic dental injuries to provide optimal treatment before the patient can seen by a dentist. An avulsed tooth should be replanted immediately, or kept moist until it can be replanted. Prognosis is related to storage media and the length of the extra-alveolar period. Teeth replanted within 5 minutes have the best prognosis. If the primary consultation is by phone the patient, or the parent, should be informed to replant the avulsed tooth. If this is not feasible the tooth should be stored in milk, saliva (oral cavity) or physiologic saline until replanted. Primary teeth are not replanted.

Pediatric dental emergencies.

Odontogenic infections and orofacial trauma are the most common types of pediatric dental emergencies. The avulsion of a child's permanent tooth or spread of an odontogenic infection through facial planes present serious medical problems requiring expedited care to achieve a favorable prognosis.

Treatment of traumatic dental injuries in children.

The major emphasis of this review rests on articles written within the past 12 months. Many of these papers comprise comprehensive surveys of treatment of various aspects of dental trauma in the primary and permanent dentition, as well as epidemiologic studies. There have also been some very good experimental studies that have attempted to standardize luxation injuries as well as tooth replantation in order to study pulpal and periodontal healing in reproducible animal models. However, it can been seen from the reference list that 1 year's production in dental traumatology would not suffice to cover the scope of the treatment needs nor to adequately orient the reader to the progress made with respect to our present knowledge of wound healing following injury and the most recent developments in the restoration of the traumatized dentition. To present an overall view of the philosophy that has evolved concerning wound healing in the dental pulp and periodontium following injury as well as innovations in the treatment of acute dental trauma, this review must of necessity delve back into the mid-1980s and probe forward into publications that are on the way in 1991.

[Treatment of dental trauma in childhood with particular consideration of splint therapy].

Injuries to the periodontium as well as to the crowns and roots of teeth are the most common results of traumatic insults in childhood. The main problem in the fixation of luxated teeth is associated with the state of dentition and the anatomy of the deciduous and permanent teeth. In a clinical follow-up examination the quality of several splints for treating luxated teeth was evaluated. We observed that some acrylic cap splints showed marked mechanical faults and poor fit. Modification of the Construction technique could eliminate such problems.

Hard tissue pediatric facial trauma: a review.

Although hard tissue injuries are uncommon in the pediatric patient, dentists may be involved in the initial assessment of these patients. In this paper, we review fractures of the facial skeleton with a focus on dentoalveolar injuries. Minimally displaced fractures in pediatric patients can be managed conservatively, while displaced fractures may require open approaches and rigid fixation. New fixation stratagems are presented, and possible facial growth disturbances resulting from trauma are discussed.

Immediate provisional restoration of postextraction implants for maxillary single-tooth replacement.

The timing of implant placement and loading following tooth extraction has recently undergone substantial reconsideration. The authors tested a protocol of immediate loading of single implants placed at the time of tooth extraction in a consecutive case series. Thirty-three patients received a single implant-supported crown to replace a maxillary anterior tooth at the time of extraction. Regular recalls were planned for the following 4 years. One implant did not integrate, and another became unstable secondary to facial trauma. Overall patient satisfaction and clinical and radiographic parameters were good.

Comparative evaluation of endodontic management of teeth with unformed apices with mineral trioxide aggregate and calcium hydroxide.

PURPOSE: The purpose of this study was to compare mineral trioxide aggregate (MTA) and calcium hydroxide (Ca(OH)2) for their efficacies and time taken for formation of apical biological calcific barriers and resolution of periapical radiolucencies, if present at baseline, in teeth with unformed apices. METHODS: Twenty nonvital permanent maxillary incisors with unformed apices, stratified according to the size of periapical radiolucencies and stage of root development, were equally allocated to MTA and Ca(OH)2 groups. In group 1 (MTA group), after 7 days of disinfection with Ca(OH)2, MTA was packed into the apical one third of the root canals and obturation with gutta percha (GP) was performed in 90% (9/10) of cases within 15 to 30 days. In group 2 (Ca(OH)2 group), obturation was performed following clinical and radiographic depiction of the apical stop. RESULTS: The mean time taken for apical biological barrier formation was 3 +/- 2.9 months for group 1 and 7 +/- 2.5 months for group 2 (P=.008). The periapical radiolucencies were resolved in 4.6 +/- 1.5 months for group 1 and 4.4 +/- 1.3 months for group 2 (P=.83). The total treatment was completed in 0.75 +/- 0.4859 months and 7 +/- 2.5 months for groups 1 and 2, respectively. CONCLUSION: The 2 materials were found to be equally efficacious in the management of nonvital teeth with unformed apices. Time taken to complete the treatment and the biological barrier formation in group 1 was significantly less than that for group 2. The healing time for periapical radiolucencies was almost identical.
