Xeroderma pigmentosum (XP) is a rare genetic disease characterized by a hypersensitivity to ultraviolet (UV) radiation leading to defective deoxyribonucleic acid (DNA) repair and predisposing to skin tumorigenesis. This paper reports the safe approaches used for the dental treatment of XP patients, controlling the ultraviolet (UV) sources at the dental office. An XP 29-year-old woman was referred for oral pain and sensitivity at the service of periodontology, UV rays were checked with a UV-meter. During the examination, the patient kept her sunglasses while the practitioner was dressed in dark colors using an anti-UV filter over the surgical light. Facial dark brown pigmentations, limited mouth opening, tumor resection scar on the tongue, moderate periodontitis, and dental caries were noticed. Moderate periodontitis and dental caries were diagnosed. Treatment was planned in collaboration with the dermatologist. Soft scaling and root planning were performed in short sessions and self-curing material was used for coronary fillings after caries removal. In taking care of XP patients, particular attention should be given by dental professionals to: i) the office management for a UV-safe environment; ii) the adoption of suitable dental care and safe biomaterials with short sessions and regular controls; and iii) the adoption of personal protections by patients and practitioners.

The anterior single missing tooth is a challenge to the dental surgeon when it comes to functional, aesthetic and biological integration especially when in adolescents or young adults, where passive eruption of the tooth is still active and where implant placement must be postponed. As a temporary or a long-term treatment, a fixed prosthesis can be placed, but in the era of maximum tissue preservation, dental practice is moving towards a harmless and conservative prosthetic therapy “the cantilever bonded bridge”.The indication is limited to the replacement of central or lateral maxillary incisor and mandibular incisors and therefore requires following a precise and rigorous clinical protocol. This article will discuss a simplified clinical realization of the ceramic cantilever bridge.The use of cantilever bonded bridges (single retainer) seems to be an excellent alternative compared to other therapeutic solutions.
