All 4 faces pain scales were found to be adequately supported by psychometric data .
When given a choice between faces scales , children preferred the WBFPRS .
Confounding of pain intensity with affect caused by use of smiling and crying anchor faces is a disadvantage of the WBFPRS .
: For clinical use , we found no grounds to switch from 1 faces scale to another when 1 of the scales is in use .
CONTEXT : Numerous faces scales have been developed for the measurement of  pain intensity in children .
It remains unclear whether any one of the faces scales is better for a particular purpose with regard to validity , reliability , feasibility , and preference .
OBJECTIVES : To summarize and systematic ally review faces pain scales most commonly used to obtain self-report of pain intensity in children for evaluation of reliability and validity and to compare the scales for preference and utility .
Self-report of pain in children treated according to the atraumatic restorative treatment and the conventional restorative treatment--a pilot study.
OBJECTIVE To compare the level of pain among children treated according to the Atraumatic Restorative Treatment ( ART ) and the Conventional Restorative Treatment ( CRT ) .  STUDY DESIGN Forty children of both genders , 4- to 7-years old , presenting Class I cavitated dentin lesions in primary molars were r and omly allocated to 2 groups . One group ( CRT ) received conventional restorative treatment using rotary instruments , while in the other one ( ART ) h and instruments were used to perform the restorations . All children were treated by the same operator A high-viscosity glass-ionomer cement ( Fuji IX ) was used to restore the teeth in both groups . Children 's pain was measured at the end of the first restorative treatment session using the Wong-Baker FACES Pain Rating Scale ( dependent variable ) . Age , gender , treatment time and treatment group were independent variables . ANOVA and ANCOVA tests were used to analyze the data . RESULTS The CRT procedure took longer than the ART procedure ( p < 0.001 ) . Children from the ART group reported less pain than those from the CRT group ( p = 0.0037 ) . Four year olds reported more pain than 5- to 7-year olds ( p < 0.0001 ) in both groups . CONCLUSIONS Restorations placed using ART were less time consuming , children felt less pain when the ART approach was used , and younger children ( 4-years ) reported more pain than the older ones for both restorative treatments
