Prevalencia de maloclusiones en la dentición primaria
Bibliographic record
Abstract
O bjetivo: El proposito de este estudio fue determinar la prevalencia de maloclusiones en la denticion primaria de ninos entre 2 y 5 anos de edad. Materiales y Metodos: Se realizo un estudio epidemiologico, descriptivo, de corte transversal. Un total de 487 ninos entre 2 y 5 anos de edad, fueron seleccionados aleatoriamente de 7 centros de educacion inicial, nacionales, del municipio la Canada de Urdaneta, Estado-Zulia, Venezuela. Una evaluacion clinica realizada por dos examinadores (Kappa inter=0,79 Kappa intra= 0,89 y 0,85) permitio registrar las caracteristicas de la oclusion en sus relaciones intra e interarcada. Resultados: La prevalencia de falta de espacios de primates y crecimiento fue 59,5% y 50% respectivamente y 59,6% de apinamiento. Un 76,6%, de los ninos presento al menos una alteracion en la relacion inter-arcada: resalte aumentado 44%, mordida profunda 31%, relacion canina clase II 24% y la mordida cruzada posterior y la mordida abierta anterior ambos con 12%. Conclusiones: Los resultados de este estudio senalan una alta prevalencia de alteraciones de la oclusion en edades temprana, siendo posible predecir riesgo de maloclusiones en la denticion permanente.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
