Objective Cephalometric measures are used to evaluate vertical facial excess (VFE), however anyone of them have been validated against a gold standard to this purpose. Also, there are differences between cephalometric results and clinical evaluation. This study pretends to validate experts' clinical diagnosis test (ECDT) as gold standard for severe VFE, with the purpose of validating further against it the cephalometric measures results. Methods A consensus (Delphi method) was done to determine if ECDT could be used as gold standard for evident VFE (n=12 experts). A scale of 9 items was initially built from literature. Validity: A convenience sample was used (n=24), which were tested by 3 experts twice. Principal factor analysis was made. Internal consistency was evaluated with Cronbach's alpha coefficient. Inter-observer and intra-observer agreement was measured using Kendall concordance coefficient. ECDT's medians were compared between groups with VFE, using Kruskal Wallis test. Results Eleven of the twelve experts agreed that clinical diagnosis can be used as a gold standard for VFE. After Principal factor analysis a 6 items' scale was made. Internal consistency was high (Cronbach's alpha= 0.8051). ECDT's medians were different in groups with different qualitative appreciation of VFE by experts, in first (p<0.0001) and second evaluation (p<0.0001). A significant interobserver agreement was found (Kendall taub, p<0,01), and a significant intra-observer agreement too (Kendall tau-b, p<0.0005). Conclusions Experts' clinical diagnosis test (ECDT) could be used as gold standard for VFE. Later on, Cephalometric measures should be evaluated using the experts' clinical diagnosis as gold standard.
Las hendiduras del labio y paladar son las malformaciones congénitas craneofaciales más frecuentes, que reflejan una falla de los mecanismos relacionados con el desarrollo embriológico de la cara y los procesos palatinos, lo que sugiere que ciertas mutaciones genéticas involucradas en la formación de la hendidura palatina producen también alteraciones en la lámina dental. Objetivo: Determinar la frecuencia, tipo y riesgo de presentación de anomalías dentales en la hemiarcada no afectada de sujetos con labio y paladar hendido unilateral no sindrómico. Metodología: Estudio observacional, analítico de casos y controles. Se utilizaron radiografías panorámicas de 336 niños, entre seis y 12 años: 111 con casos y 225 controles. Se identificaron las siguientes anomalías dentales: agenesias, supernumerarios, microdoncia de incisivos laterales, taurodontismo, transposiciones, impactaciones y rotación de incisivos centrales. Se realizó análisis bivariado, utilizando pruebas χ2 y Fischer y regresión logística condicional con efectos fijos, para realizar los cálculos de estimadores de riesgo. Resultados: El 48.6% de los niños con labio y paladar hendido unilateral no sindrómico presentaron al menos una anomalía dental en la hemiarcada no afectada, mientras que ésta se presentó en el 36% del grupo control. Las anomalías más frecuentes fueron agenesia de incisivos laterales maxilares y de segundos premolares maxilares con diferencia significativa (p = 0.00). Los sujetos con labio y paladar hendido unilateral no sindrómico tuvieron tres veces más riesgo de presentar anomalías dentales que los sujetos sanos (OR = 2.9; 95% IC [1.4-6.0], p = 0.002). Conclusiones: Se encontró una mayor prevalencia y mayor riesgo de anomalías dentales en la hemiarcada no afectada de sujetos con labio y paladar hendido unilateral no sindrómico comparada con la población sin hendidura oral
