[Photoprotection and its implications for drug safety].

Appropriate photoprotection plays a key role in the safety of using medicinal preparations whose active substances may induce photosensitivity reactions. This aspect applies not only to drugs applied topically to the skin, but also systemically. Drug-induced photosensitivity reactions to light depend on the active substance contained in the medicinal product and its dose, which translates into the concentration in the skin, the type of ultraviolet radiation, its intensity and exposure time.

Dental Hygiene Students' Perceptions of Importance and Confidence in Applying Motivational Interviewing During Patient Care.

Motivational Interviewing (MI) is an evidence-based, patient-centered counseling approach for eliciting behavior change. In 2012, the University of Michigan (U-M) Dental Hygiene Program significantly enhanced their behavior change curriculum by reinforcing and building upon the Motivational Interviewing segment. The purpose of this study was to examine students' perceptions of the importance of MI and their confidence in applying it during patient care.

Pre-eruptive intracoronal resorption of a permanent first molar.

For the last 70 years, the phenomenon of pre-eruptive intracoronal resorption (PIR) has been described in the literature, including a number of case reports illustrating the challenges clinicians face in diagnosing and managing these resorptive defects. Pre-eruptively affected teeth can be difficult to access and posteruptively they are difficult to diagnose because the defects resemble caries. Many times, these defects are not detected until after eruption, when the majority are diagnosed as dental decay and teeth are often subjected to surgical tooth restoration.
