How standard deviation contributes to the validity of a LDF signal: a cohort study of 8 years of dental trauma

摘要: The aim of this cohort study was to document the potential laser Doppler flowmetry (LDF) for diagnosing tooth vitality in traumatized teeth a population 88 referred patients with dental trauma over period 8 years (2011–2018). main reason refer discoloration (26%), and cause traffic injury (35%). Taking into account that referral LDF is best given within week after trauma, 66% referrals were overdue. In 73% cases, root canal treatment could be avoided, 65%, presence fixed orthodontic retainer showed beneficial pulp recovery. Data 394 collected submitted multilevel modelling statistics. As general conclusion, both perfusion concentration values proved highly reliable appreciation vitality. difference variability standard deviation range measurements involving intra-subject control statistically significant discriminating between vital non-vital pulps. teeth, diagnostic combination LDF, sensibility tests peri-apical X-ray advised.
