## Abstract

Background/Objectives: Accurate drug dosage calculation in pediatric dentistry represents an essential component of everyday clinical practice. However, manual calculation methods, reliance on memory, and inconsistent pharmacological education often lead to uncertainty among practitioners. Methods: To support clinicians in this process, a mobile application—Dent.IN CALC—was developed as a rapid, evidence-based, and user-friendly tool. The app allows the input of age and weight to instantly generate recommended and maximum safe dosages of commonly prescribed antibiotics, analgesics, and local anesthetics. Additionally, it includes a list of corresponding pharmaceutical preparations available on the local market. A preliminary evaluation among sixty dentists revealed significant variability in dosage knowledge and confirmed the need for digital tools that facilitate accurate and efficient prescribing. Results: Most users rated the app as intuitive, time-saving, and highly beneficial for daily practice (mean satisfaction score 4.7 ± 0.4; 95% would recommend the app). Conclusions: The Dent.IN CALC app shows strong user acceptance and demonstrates how digital solutions can streamline workflow and support clinicians in routine pediatric pharmacological decision-making.
