ABSTRACT
The standard eruption of the permanent dentition in growing patients is influenced by multiple environmental factors. The objective of this research was to study the relationship between height and weight percentiles and the eruption of the permanent dentition. The design of the study was transversal based on the review of the clinical history, visual dental inspection, weight and height indicators, and their respective percentiles in patients in the mixed and definitive dentition stage. The descriptive and comparative analysis of the data was carried out with the statistical software R version 4.1.1. The sample size was 725 participants. The mean age of eruption of the first tooth was 8.0. The eruption sequence in the upper arch was first molar, central and lateral incisor, first premolar, canine, second premolar, and second molar. In the lower arch, the eruption sequence was: central incisor, first molar, lateral incisor, canine, first and second premolar, and second molar. The most frequent weight percentile was P50-97 (50.34%) and height P3-50 (53.38%). Weight (0.0129; 0.0426; 0.0495; 0.000166) and height (0.00768; 0.00473; 0.00927; 10-5) variables significantly influenced dental eruption. The factor that most influences the eruption of the permanent dentition is the height percentile.
ABSTRACT
The aim was to analyze the relationship between BMI (body mass index) and the sequence and chronology of the eruption of permanent teeth in a sample of Spanish children. Methods: The study design was descriptive, cross-sectional, observational, and epidemiological. Patients of pediatric age were included. Emerged teeth, and patient's age, race, and sex were recorded. The nutritional status of the child was assessed by calculating the BMI, according to the WHO parameters. Statistical analysis was carried out with a confidence interval of 95%. A prediction model with logistic regression models was obtained. Results: A total of 725 pediatric patients between 4 and 14 years old were analyzed. BMI acts as a predictor variable for eruption symmetry, as it was most frequent in overweight children (p < 0.001). The probability of symmetry in dental eruption increases for South American children, for an extra month of age, and each meter of height. BMI had an influence in the first tooth to appear only in the fourth quadrant. BMI did not seem to influence present teeth, and the sequence of permanent dental eruption was not influenced by the BMI category. Conclusions: Age, weight, height, and BMI act as significant predictors for eruption symmetry. BMI does not produce alterations in the eruption sequence of the permanent dentition.
ABSTRACT
Estudiar la emergencia y secuencia deerupción es indispensable para establecer protocolos de prevención y tratamientos a nivel odontopediátrico, ortodóncicoy forense. En 1933 se estableció el iniciode la erupción definitiva a los 6 años y sutérmino a los 13 a excepción de los cordales. Sin embargo, posteriormente se hanobservado variaciones determinadas porfactores raciales, hormonales, mejoras enla alimentación y parámetros corporales.Con el objetivo de conocer posibles cambios en la cronología y secuencia de erupción en dentición permanente y poblaciónespañola se ha llevado a cabo una búsqueda bibliográfica en los buscadoresPubmed, Scielo, Dentistry y Oral Science.Empleando una estrategia avanzada conoperadores boleanos AND y OR. Losresultados obtenidos advierten de unaemergencia de la dentición permanentemás precoz en el sexo femenino. Los autores coinciden en que el primer diente enerupcionar es el incisivo central inferior yel último el segundo molar superior. Sinembargo, en cuanto a la edad media dela emergencia del primer diente no hayconsenso.Los dientes permanentes mandibulareserupcionaban antes que los maxilares.La secuencia de erupción más prevalente en la Arcada superior es: primer molar, incisivo central, incisivo lateral, primerpremolar, segundo premolar, canino ysegundo molar. Y en la inferior: incisivocentral, primer molar, incisivo lateral, canino, primer premolar, segundo premolary molar. Se concluyó que existía una correlación directa entre el tiempo de erupción de los dientes temporales y la de los permanentes canine, first premolar, second premolar and second molar.To conclude, we noticed an extremely direct relation between the eruption time of the temporal teeth and thepermanent teeth (AU)
In order, to develop prevention andtreatment protocols in pediatric,orthodontic and forensic dentistry, it isvitally needed to study the sequence andchronology of eruption of the permanentteeth. Logan and Kronfield establishedthat the eruption of permanent teethstarted at the age of six and finished atthe age of 13, except the third permanentmolars. Nevertheless, in later studies thisrange of age has been modified due toan early puberty, an improvement in thenutrition and due to other factors, suchas, race, weight, and heigh. Our objectiveis to get to know the current situationabout the chronology and sequence ofpermanent dentition.We did a bibliographic review in differentweb browsers, such as, PubMed, Scieloand Dentistry and Oral Science. Weapplied an advanced strategy searchingwith AND and OR. The results warn usthat the permanent teeth erupted earlieralways in the female sex. All the authorsagree that the first tooth to erupt is thelower central incisor and the last one isthe upper second molar. Despite this fact,regarding the media age of eruption therewas not agreement between the authors.Therefore, we can conclude thatpermanent teeth erupt before in themandible than in the maxilar. The mostprevalent sequence in the maxilar was:first molar, central incisor, lateral incisor,first premolar, second premolar, canineand second molar. In the mandible was:central incisor, first molar, lateral incisor(AU)
