The prevalence of molar incisor hypomineralization in the United States is unknown. The condition is defined via the presence of demarcated opacities of varying color, porous enamel, advanced susceptibility or progression of dental caries, and sensitivity. The purpose of this study was to establish the prevalence of molar incisor hypomineralization (MIH) in Pittsburgh, Pa., USA. A total of 104 patients (64 females and 40 males ranging in age from seven to 32 years) from the University of Pittsburgh were screened for the clinical signs of MIH between May 15 and July 31, 2019. MIH was defined according to international guidelines. A total of 9.6 percent of patients screened presented with the clinical signs of MIH; 15.4 percent of patients screened presented with clinical signs aligning with dental fluorosis. Molar incisor hypomineralization is prevalent and clinically relevant in Pittsburgh. American clinicians should start recording the diagnoses of MIH to facilitate establishing national prevalence data and increase knowledge and treatment.
美国磨牙切牙矿化不全的患病率尚不清楚。该病症通过不同颜色的界限性釉质混浊、多孔性牙釉质、龋齿的高度易感性或进展以及敏感性来定义。本研究的目的是确定美国宾夕法尼亚州匹兹堡市磨牙切牙矿化不全（MIH）的患病率。2019年5月15日至7月31日期间，对来自匹兹堡大学的104名患者（64名女性和40名男性，年龄在7至32岁之间）进行了MIH临床体征筛查。MIH根据国际指南进行定义。共有9.6%的筛查患者出现MIH临床体征；15.4%的筛查患者出现与氟斑牙相符的临床体征。磨牙切牙矿化不全在匹兹堡市很普遍且具有临床相关性。美国临床医生应开始记录MIH的诊断情况，以便于建立全国患病率数据，并增加相关知识和治疗方法。
