[Comfortable initial periodontal therapy: step by step].

With the transition of the medical model from the traditional biomedical model to the biopsychosocial one, there is a growing trend and requirement for oral operations that prioritize comfort, pain management, minimally invasive techniques, and visualization. Consequently, demands for comfortable dental treatments among individuals are increasing. However, initial periodontal therapy is often accompanied by pain, and patients' reactions to pain range from nervousness to dental fear, such as irritability, hyperventilation, even nausea, vomiting, and refusal to cooperate, which make the implementation of initial periodontal therapy difficult or even impossible. This article will focus on three key steps: firstly, the preparation of the clinic, the acquisition of patients' trust and the implementation of preventive sedation before treatment; secondly, the use of comfort operation and nursing, psychological intervention measures, local anesthesia, and sedation techniques during treatment; thirdly, the health education and follow-up after treatment. By addressing these aspects, we aim to clarify how to perform comfortable initial periodontal therapy step by step.
