“…Allergic reactions towards dental materials constitute T‐cell‐mediated allergic reactions of the delayed type. For diagnostics of this reaction, patch testing is employed according to the guideline of the German Contact Dermatitis Research Group (GCDRG) of the German Society of Dermatology [4]. Prophetic testing of patients with no oral mucosal lesions to exclude possible allergy to dental materials is advised against, as patch testing cannot provide a sensible answer here.…”

SummaryThe oral mucosa is constantly exposed to a large number of potentially irritating and sensitizing dental materials. Dental materials used for fillings and fixed or removable replacements must have a good biocompatibility. Metals including palladium are used in alloys for the production of the core of crowns, onto which porcelain is bonded for the generation of an artificial tooth to which the patient can develop an allergic contact dermatitis. The clinical manifestations of contact allergy to dental materials are not uniform. Objective symptoms of a contact allergy include a stomatitis and lichenoid reactions. However, patients may present with more subjective affections of the oral mucosa including burning, pain and dryness which need to be differentiated from a real contact allergic reaction. In this article we focus on the management of contact allergy to dental materials.

Background Guava has benefit phytochemicals that are important for skin‐disorder treatment. Nevertheless, its efficacy against oily skin has never been reported. Aims The guava toner was developed and clinical evaluated. Methods The base toner was formulated, accelerated stability tested, and sensory‐evaluated in 10 volunteers. The highest preference base was incorporated with guava extract, stability examined, and skin irritation assessed in 21 volunteers by a single application close patch test. Anti‐sebum efficacy was split‐face, randomized, single‐blind placebo‐controlled evaluated in 21 volunteers for 28 days and monitored by Sebutape® on forehead and nose. Results The stable toner base with the greatest preference (83.20 ± 1.85%) was incorporated with 3%, 4.5%, and 6% of guava extract. The toners were stable with none of skin irritation. The toner with 6% guava extract was selected for efficacy evaluation. Guava toner significantly reduced oiliness of forehead (13.10 ± 3.67%, P < 0.05) and nose (21.43 ± 3.21%, P < 0.001) better than the base toner. The activity on nose was significantly noted (10.72 ± 3.51%, P < 0.05) since the 3rd week of application. Conclusions Anti‐sebum guava toner was efficiently evidence approved and suitable for a daily application to improve the efficacy.
