Introduction. The "Lingual Frenulum Assessment Protocol in Babies", popularly known as Teste da Linguinha (TL), is a neonatal screening test mandatory in all hospitals and maternity hospitals in Brazil since December 2014. The TL aims to diagnose ankyloglossia that may have a negative impact on breastfeeding. Objectives. 1. To estimate the prevalence of ankyloglossia in healthy newborns from a public maternity in Rio de Janeiro; 2. To evaluate the reliability and validity of the Lingual Frenulum Assessment Protocol in Babies when it is used as a screening test. Methods. This study was conducted at a public maternity in the city of Rio de Janeiro, Brazil. The TL was applied to a sample of healthy term newborns, weighing 2.500 g or more, within 48 hours of birth. Data were collected by three trained examiners (two pediatric dentists and one speech therapist), through interviews with the mothers, assessment of breastfeeding and the application of the TL to newborns. One month after the child´s birth, mothers were interviewed by phone by undergraduate dental students in order to collect information about their experiences with breastfeeding after hospital discharge. The assessment of the reliability of the TL included the measurement of its internal consistency and stability. The validity of the protocol was analyzed by the correlation between the scores of the instrument and those of self-perceived indicators of breastfeeding success and failure, and professionally determined breastfeeding difficulty as measured by the Adapted Breastfeeding Observation Aid UNICEF protocol. Statistical analysis was performed with Stata 14.0® software. Results. Total sample comprised 268 dyads mothers/child, recruited between August 25 and September 30, 2015. The prevalence of anklyloglossia was 2.24% (IC 95% = 0.83; 4.81%). The inter-rater reliability among the three examiners as measured by the intraclass correlation coefficient was 0.77 (95% CI: 0.64, 0.89) and the Cronbach's alpha coefficient for internal consistency was 0.28 (95% CI lower limit: 0.14). The correlations between the total TL score and self-perceived difficulty to breastfeed, satisfaction with breastfeeding, and pain while breastfeeding were respectively 0.05 (p = 0.42), 0.01 (p = 0.87) and 0.007 (p = 0.92). The correlation between the TL score and the adapted UNICEF protocol was 0.27 (p <0.001). Conclusion. The prevalence of anklyloglossia was very low. The "Lingual Frenulum Assessment Protocol for Babies" used as a screening test presented acceptable stability and low internal consistency. It was not possible to confirm its validity. These findings suggest that the use of the "Lingual Frenulum Assessment Protocol for Babies" for identifying newborns with ankyloglossia that may negatively interfere with breastfeeding should not be recommended.
