The correlation of organoleptic and instrumental halitosis measurements.

Numerous detection systems are available for measuring halitosis. In order to examine their agreement, a study was conducted comparing four selected measuring methods in 100 subjects (52 females, 48 males; mean age: 25 years). Organoleptic halitosis measurement was carried out by an odor judge, and compared with instrumental halitosis measurement by sulfide monitoring using Halimeter, Fresh Kiss, and Halitox (halitosis linked toxin detection assay), with which both VSC (volatile sulphur compounds) and polyamines can be detected. The results show that the values recorded by the Halimeter correlated best with the organoleptic assessment and the least with the results of Fresh Kiss.

[Cervicofacial actinomycosis: two case reports]. / Zervikofaziale Aktinomykose: zwei Fallberichte.

Infectious diseases transmitted by actinomycosis species cause severe destructive lesions. This rare and specific infection is mainly found in the orofacial regions. Causes of any hard tissue swelling in the jaw have, thus, to be assessed carefully. When actinomycosis is identified, a surgical intervention with curettement, draining and long-term antibiosis is required. The aim of the current article is to describe two clinical cases and to show the necessity of both, microbiological and histological laboratory diagnostics, to hedge the clinic diagnosis.

Dental trauma in adults in Switzerland.

Most epidemiologic studies of dental trauma are restricted to children and sports. The goal of the present study was to collect information on dental trauma in as many Swiss adults as possible. For that purpose data of the largest insurance company of Switzerland (SUVA) were evaluated and compared for the years 1992 and 2002. In these 2 years 23 000 dental injuries were reported to all insurance companies in Switzerland. Most often the upper central incisors were injured. However, in 20% posterior teeth were also affected. In 1992 most of the dental trauma was experienced by 30-39 year olds, in 2002 by 40-49 year olds. Regardless of the year, most of the injuries occurred at home; more than one-fifth of the injuries were sports related. Most common injuries were crown fractures without pulp involvement. In less than 10% of all cases more complicated injuries like avulsions or crown-root fractures occurred. Most traumatic injuries were treated by direct fillings and custom-made crowns; more involved treatments were required less often. Comparison of the years 1992 and 2002 showed that the numbers of and causes for injuries had hardly changed in these 10 years. However, the choice of therapy was related to the general development of dental medicine, which became especially apparent in the fields of adhesive dentistry and implantology.
