Purpose: The purpose of this study was to estimate the prevalence of white spot lesions (WSLs) in various practice settings and patient populations, and to gather information about the treatment timing and modalities used by pediatric dentists in the United States. Study design: A fourteen question, multiple choice, electronic survey was developed and distributed to 6,092 active American Academy of Pediatric Dentistry (AAPD) members. Results: A total of 625 active members responded, garnering a 9.7% response rate. Before treatment, there were significantly more WSLs reported in Corporate practice than Multi-Doctor Practice (P=0.002), and significantly more WSLs in Academics/Hospital-Based Practices than in Multi-Doctor Practices (P=0.002). For WSLs after treatment, there were significantly more WSLs in Academic/Hospital-Based practices than in single-practitioner settings (P=0.003). Approximately 38% of pediatric dentists preferred to treat WSLs before, during or after orthodontic treatment, while 23% treat only before and 20% treat only after treatment. The three most common treatment modalities for WSLs, were prescription fluoride toothpaste (5000 ppm), fluoride varnish, and fluoride rinse. Approximately 47% of respondents reported they were “very comfortable” treating WSLs and 31.0% felt “comfortable.” Conclusions: The prevalence of WSLs differed across types of practice. There is no agreement among pediatric dentist as to timing and treatment modalities for WSLs.
