Case ReportsLocalization of paraoral soft tissue calcifications: the known object rule.
The interpretation of panoramic radiographs requires an understanding of the formation of real and ghost images in rotational panoramic radiology. This article illustrates the use of principles of interpretation in panoramic radiology to identify paraoral soft tissue calcifications, which appear as lesions in the third molar-ramus region of the mandible. The known object rule, a variation of the buccal object rule, is presented as an aid in identifying soft tissue calcifications of the region of the head and neck.

Case ReportsNasotracheal tube obstruction from a central incisor. Report of a case.
After maxillofacial trauma, teeth and other objects can become potential foreign bodies. Whenever possible, careful examination before intubation should be undertaken to avoid serious morbidity secondary to aspiration. The anesthesiologist should be informed and necessary preventive measures taken. This article describes a situation in which this not being done could potentially have led to serious complications.

Effect of nystatin and chlorhexidine digluconate on Candida albicans.
Polyene antibiotics such as nystatin and amphotericin B are among the most widely recommended drugs for use against oral candidiasis. It is also generally accepted that chlorhexidine gluconate is an appropriate adjunct or an alternative to specific antimycotic drugs. ⋯ The results of the MIC study and the presence of a precipitate in all combinations of nystatin and chlorhexidine digluconate showed that the combination of the drugs is not effective in vitro against Candida albicans. The most likely reason is that a low solubility chlorhexidine-nystatin salt is formed, thus rendering the combined drug complex ineffective as an antibiotic agent.

Randomized Controlled Trial Clinical TrialEffect of chlorhexidine rinsing on the oropharyngeal ecology in patients with head and neck cancer who have irradiation mucositis.
Oral flora is thought to contribute to irradiation mucositis in patients with head and neck cancer. Neglect of oral hygienic care may also contribute to mucositis. The purpose of this prospective, randomized, placebo-controlled, double-blind study was to evaluate the effect of chlorhexidine 0.1% mouthrinses on oral flora and irradiation mucositis. ⋯ The colonization patterns of Candida species, Streptococcus faecalis, staphylococci, and Enterobacteriaceae, Pseudomonadaceae, and Acinetobacter species were not influenced by 5 weeks of use of chlorhexidine rinses when compared with the placebo. No differences were seen between the two study groups in the development and severity of mucositis. In conclusion, suppression of oral flora and a lowering of the severity of mucositis by means of disinfecting mouthrinses were not successful.

Clinical Trial Controlled Clinical TrialThe effects of two different dental local anesthetic solutions on plasma potassium levels during third molar surgery.
The influence of two different dental local anesthetic solutions on plasma potassium levels during third molar surgery has been investigated in a single-blind cross-over study in twelve volunteers. The solutions employed were 2% lidocaine (xylocaine) containing 1:80,000 epinephrine and 3% prilocaine (Citanest) containing 0.03 IU/ml felypressin. The different treatments produced similar effects on blood pressure and heart rate. However, the effect on plasma potassium levels differed significantly in the early postinjection period.
