Orthodontic treatment--yes or no? A difficult decision in some cases. A contribution to the discussion.

Reasons for orthodontic treatment are discussed on the basis of 1. evidence-based knowledge from the literature, 2. viewpoints based on clinical experience, 3. case presentations. Viewpoints regarding prophylactic aspects of orthodontic treatment in relation to oral health are critically evaluated. The clinically based experience that dentofacial esthetics is the main reason for most patients requesting orthodontic treatment is also well documented in the literature. Against this background, psychosocial aspects as an indication for orthodontic treatment deserve greater recognition.

[The incidence of microlaryngoscopy associated complications].

BACKGROUND: The frequency of local and cardiovascular side effects of microlaryngoscopy is generally underestimated. There are no data available in the literature from recent and prospective clinical trials. PATIENTS AND METHODS: We examined 81 patients between 03/1998 and 03/2000 who underwent microlaryngoscopy in our department. This was done following a standard protocol before, during and after surgery. Side effects of endotracheal intubation were avoided by using supraglottic jet-ventilation. RESULTS: In 79% of our cases we encountered side effects due to the microlaryngoscopic procedure.86% of them were reversible lesions,hematomas and edemas of the mucous membranes or mild cardiovascular dysregulations. In two cases there was a dental complication (one fracture, one dislocation), and seven cases of moderate hemodynamic effects were noted. CONCLUSIONS: The incidence of tissue damage caused by microlaryngoscopic endoscopes is much higher than commonly assumed in clinical practice. This has to be explained to the patient when obtaining his written consent to a certain microlaryngoscopic procedure and to be considered during the postoperative follow up.The consequent use of tooth protection and a good control of muscle relaxation and analgesia can be effective in preventing side effects.

Ameloblastin fusion protein enhances pulpal healing and dentin formation in porcine teeth.

Ameloblastin (Ambn, also named "amelin" or "sheathlin") is a protein participating in enamel formation and mesenchymal-ectodermal interaction during early dentin formation in developing teeth. Experiments have demonstrated an association between Ambn expression and healing of acute pulp wounds. The purpose of this study was to investigate if local application of recombinant fusion Ambn (rAmbn) could influence reparative dentin formation in pulpotomized teeth. In this randomized, double-blinded study, pulpotomy was performed in 28 lower central incisors in 17 adult miniature pigs. Following the surgical procedure, the exposed pulp tissue was covered either with rAmbn or with calcium hydroxide. After 2, 4, or 8 weeks, the teeth were extracted and examined by histomorphometry and immunohistochemistry using antibodies against porcine ameloblastin, collagen type I, and dentin sialoprotein (DSP). In rAmbn-treated teeth, a substantial amount of newly formed reparative dentin was observed at the application site, completely bridging the pulpal wound. Dentin formation was also observed in calcium hydroxide-treated teeth; however, the amount of reparative dentin was significantly smaller (P < 0.001) than after rAmbn treatment. Immunohistochemistry confirmed that the new hard tissue formed was similar to dentin. This is the first time a direct link between ameloblastin and dentin formation has been made in vivo. The results suggest potential for rAmbn as a biologically active pulp-dressing agent for enhanced pulpal wound healing and reparative dentin formation after pulpotomy procedures.

[Medical expert opinions in oral and maxillofacial medicine regarding incisor tooth trauma].

BACKGROUND: The treatment of traumatized patients plays a significant role in the everyday life of oral and maxillofacial surgeons as well as of dentists. Traumas of incisor teeth account for a considerable part. These traumas are often followed by lawsuits. The aim of this retrospective analysis was to highlight aspects of these lawsuits of special significance and to show the consequences for surgeons and general practitioners. MATERIAL AND METHODS: A total of 398 medical expert opinions were evaluated. Moreover, an online search of databases for relevant court decisions was performed. Analysis was initially based on formal aspects of the cases and reports. It was later supplemented by a differentiated assignment of the questions addressed by the courts to the expert consultants. RESULTS: In 97 (24%) medical expert opinions traumas of the incisor teeth were the main subject. In 35% the trauma was caused by traffic accidents followed by assaults. In one-third the medical expert opinion was commissioned by accident insurance companies. The compensation for pain and suffering was between 1500 and 2000 euros per lost tooth. CONCLUSION: Traumas of incisor teeth are often followed by litigations. Clinicians performing first treatment should ensure that documentation of clinical and radiological findings is detailed and complete. This documentation plays a decisive role in medical expert opinions.

Pain: a poor parameter of evaluation in dentistry.

In summary, we must be aware of the limitations of our instruments for determining success. A diagnosis is achieved by developing a composite picture through a keen gathering of all factors leading to the disease. Pain must surely be considered in patient management and patient-dentist rapport, but to allow our judgment to be swayed by pain alone is no more rational than to hinge our diagnosis upon a single other test. It is of paramount importance that we realize that, pulpally, periodontally, and periapically, there is no correlation between amount of destruction and reported presence or absence of pain. Pain is a poor parameter of evaluation.
