Facial expression, including smiling, is an important means of universal communication and an understudied area in dentistry. Currently there is limited availability of data on smile psychology in either general or cosmetic dental literature. However, the number of cosmetic dentistry patients is increasing and many require and desire physical changes that restore or enhance facial expressions, appearances, and smiles. Cosmetic dentistry patients, particularly those presenting with dental anxiety or phobia, require a more detailed physical and psychologic assessment due to their habitual avoidance of dental care and subsequent oral health deterioration. Increasing knowledge and data facilitate the development of new intervention and treatments for anxious and phobic dental patients. These new developments strengthen the dentist-patient partnership to foster optimal dental results.
面部表情，包括微笑，是一种重要的通用交流方式，也是牙科领域一个研究不足的领域。目前，无论是普通牙科文献还是美容牙科文献中，关于微笑心理学的数据都很有限。然而，美容牙科患者的数量正在增加，许多患者需要并希望通过身体改变来恢复或增强面部表情、外观和微笑。美容牙科患者，尤其是那些患有牙科焦虑症或恐惧症的患者，由于他们习惯性地回避牙科护理以及随后的口腔健康恶化，需要更详细的身体和心理评估。知识和数据的增加有助于为焦虑和恐惧的牙科患者开发新的干预措施和治疗方法。这些新进展加强了医患合作关系，以促进达到最佳的牙科治疗效果。
