Validity of demirjian and nolla methods for dental age estimation for Northeastern Turkish children aged 5?16 years old
2012
Objective: To evaluate the applicability of Demirjian and Nolla methods for northeastern Turkish population. Material and Method: A retrospective study was performed on panoramic radiographs of 673 subjects aged 5–15.9 years. The mean dental age (DA) according to the Demirjian and Nolla methods were compared to the mean chronological age (CA). Results: The mean CA of the study sample was 10.37±2.90 and 10.03±2.81 years for females and males, respectively. Using the Demirjian method, the mean estimated DA was 11.26±3.02 years for females and 10.87±2.96 years for males. For Nolla method, the mean estimated DA was 9.80±3.41 and 9.53±3.14 years for females and males, respectively. The mean diff…
Rhythmic priming of grammaticality judgments in children: Duration matters
2020
Abstract Research has shown that regular rhythmic primes improve grammaticality judgments of subsequently presented sentences compared with irregular rhythmic primes. In the theoretical framework of dynamic attending, regular rhythmic primes are suggested to act as driving rhythms to entrain neural oscillations. These entrained oscillations then sustain once the prime has finished, engendering a state of global enhanced activation that facilitates the processing of subsequent sentences. Up to now, this global rhythmic priming effect has largely been shown with primes that are approximately 30 s or more. To investigate whether shorter primes also facilitate grammaticality judgments, two expe…
Relationship between pulp-tooth volume ratios and chronological age in different anterior teeth on CBCT
2017
Background The CBCT imaging technique exhibits proper accuracy to determine the internal anatomy of teeth. Therefore, this technique can use to estimate age by measuring the amount of decrease in the volume of the pulpal cavity of teeth. The aim of the present study was to evaluate the correlation between chronological age and pulp-to-tooth volume ratios in anterior teeth with the use of the CBCT technique and to determine a regression model to estimate human age. Material and methods In this present descriptive-analytical study, 122 subjects (46 males and 76 females), with an age range of 13-70 years, were evaluated. The MIMICS software program was used to determine the pulp-to-tooth volum…
Does the Relation between Rapid Automatized Naming and Reading Depend on Age or on Reading Level? A Behavioral and ERP Study
2018
Reading predictors evolve through age: phonological awareness is the best predictor of reading abilities at the beginning of reading acquisition while Rapid Automatized Naming (RAN) becomes the best reading predictor in more experienced readers (around 9–10 years old). Those developmental changes in the relationship between RAN and reading have so far been explained in term of participants' age. However, it should be noted that in the previous experiments age always co-vary with participants reading level. It is thus not clear whether RAN-reading relationship is developmental in nature or related to the reading system itself. This study investigates whether the behavioral changes in the rel…
Comprehension of Generalized Conversational Implicatures by Children With and Without Autism Spectrum Disorder
2018
This study evaluates the comprehension of generalized conversational implicatures (GCI) in children with and without autism spectrum disorder (ASD), using a GCI test constructed based on the Levinson model, which distinguishes between three types of implicatures: type Q (or scalar: “what is not referred to does not occur”); type I (“by default, it is not necessary to say what can be assumed”); and type M (“if someone is expressing something in a not very simple or marked way, it is because s/he is describing a situation that is not very typical, frequent, or prototypical”). In addition to the ASD group (n = 22), two comparison groups were utilized: a group matched on chronological age with …
¿Depende el desarrollo de la RAN de la edad de inicio de la lectoescritura?
2018
Antecedentes:La habilidad del alumno para nombrar rápidamente estímulos familiares (RAN) es un factor implicado en el rendimiento lector evaluable de forma indiscriminada a lo largo de los primeros años de escolarización. El objetivode este estudio, pues, es analizar si la adquisición de dicha habilidad depende de variables relacionadas con una iniciación temprana a la lecto-escritura o si su desarrollo se relaciona con factores de madurez cronológica. Método: Para ello se aplicó la prueba RAN a 71 niños de 6-7 años croatas (cultura en la que la iniciación a la lectura es más tardía); a 44 niños de 4-5 años españoles (equiparando los dos grupos por edad de inicio de la lecto-escritura) y a …
