[Vertical and horizontal jaw relations in reconstructive dentistry. A critical review].

Despite comprising one of the routine duties of dental practitioners, the methods used for the determination of the vertical and horizontal jaw position differ considerably from dentist to dentist. For the overwhelming majority of patients, however, the techniques generally applied for the maxillomandibular relationship record appear to lead to acceptable results. No method seems to be clearly superior to the other. As far as the determination of the horizontal mandibular position (centric relation interocclusal record) is concerned, bimanual manipulation has shown to be particularly reliable. The decisive factor, apart from any preferred method, is that the chosen therapeutic mandibular position be reproducible for both the treatment provider as well as the patient.

[Atypical odontalgia].

In spite of its first description by the English surgeon JOHN HUNTER more than 200 years ago, atypical odontalgia (AO), or phantom tooth pain, is not universally known among dentists. AO is a persistent neuropathic pain which may be initiated after deafferentiation of trigeminal nerve fibers following root canal treatment, apicectomy, or tooth extraction. In the absence of pathological clinical or radiological findings, the diagnosis is made by exclusion. After a thorough patient education about the condition, pharmacological and psychological pain management is required. Invasive and irreversible treatment attempts are contraindicated.

[Therapeutic local anesthesia for the management of atypical odontalgia. A clinical case series].

The management of patients diagnosed with atypical odontalgia (AO) is a challenging task. The aim of this longitudinal clinical case series was to document the effect of a 4% carticaine solution without epinephrine among ten patients with AO. Once or on two successive days, 1.7 ml of the local anesthetics was injected buccally in the area of the perceived pain. Pain intensity was recorded four times daily by each participant, beginning at least two weeks prior to the treatment and ending at least four weeks thereafter. The main outcome parameter was pain reduction (in percent) four weeks after treatment compared to the average pain intensity before the injection(s). In addition, study participants were asked to rate their satisfaction with the treatment. Four weeks after treatment, seven of the ten patients experienced significantly less pain than before. Among five individuals, there was a significant pain decrease (about 30% or more). Patient satisfaction was not significantly associated with the amount of pain reduction. Considering the limited treatment options and their side effects, injections with epinephrine-free carticaine seem to be a measure worth to be taken into consideration. Although results gained from uncontrolled case series have to be interpreted with caution, the findings of this observational study sound promising.

[German language articles on controlled trials in oral and maxillofacial surgery].

Various authors have shown that only a part of all reports of randomized controlled trials (RCTs) and controlled clinical trials (CCTs) are accessible in Medline. However, the validity of systematic reviews and meta-analyses heavily depends on the completeness of the identified studies published for a particular clinical problem. Therefore, an additional manual search in dental/medical journals is often indispensable. The major purpose of the present article was to identify all published reports of RCTs and CCTs dealing with topics covered by the discipline oral and maxillofacial surgery. The journals Deutsche Zahnärztliche Zeitschrift, Schwetzer Monatsschrift für Zahnmedizin, Mund-, Kiefer- und Gesichtschirurgie, Stomatologie, and Stomatologie der DDR were manually searched. The publication type of the identified clinical trial reports was determined and compared with Medline. Among the 14,860 articles perused, 202 RCTs and 396 CCTs were identified. 74 RCTs (36.6%) and 104 CCTs (26.2%) referred to topics related to oral and maxillofacial surgery. Of the 74 RCT reports, 44 are included in Medline, and 14 are indexed with the correct publication type term. The majority of RCTs were carried out in the field of oral and maxillofacial surgery. Unfortunately, only a part of German-language reports of dental clinical trials are accessible in Medline. Therefore, a literature search restricted to this database is likely to be incomplete, possibly leading to biased results.

[Practice-related diagnostic classification of orofacial pain].

In this article, a practical diagnostic classification of orofacial pain for use in the general dental practice is presented. In contrast to the detailed taxonomy proposed by Okeson (1995), this classification is limited to those pain conditions dentists are confronted with most frequently. Furthermore, the fundamental differences of somatic versus neuropathic pain, localized versus widespread pain, and acute versus chronic pain are emphasized. Principles of managing the different pain entities are suggested.

[Relationship between occlusion and myoarthropathy. Introduction of an integrating neurobiological model].

For many decades, the relationship between occlusal factors and temporomandibular disorders has been discussed controversially in the dental literature. After a brief description of current points of view about this topic, a recently published clinical trial by Le Bell et al. (2002) is summarized. The results of this study are discussed on the basis of a novel neurobiologic model, which is based on the heterogeneous activation of the masticatory musculature. This model appears to be suitable to explain the pathogenic and therapeutic effects due to occlusal management of patients with myofascial facial pain.
