Evaluación de Lesiones Periapicales Utilizando Tres Índices sobre Tomografía Computarizada Cone Beam

El uso de tomografía computarizada Cone Beam (CBCT) puede favorecer el diagnóstico temprano de periodontitis apical e influir en su pronóstico y tratamiento; sin embargo, no existe una estandarización entre los índices que determinan la presencia de lesiones periapicales en esta técnica radiológica. Es por tal motivo que, el objetivo de este estudio fue evaluar lesiones periapicales utilizando tres índices sobre CBCT. La población de estudio estuvo conformada por todas las CBCT realizadas en un centro radiológico peruano durante un año, se realizó un muestreo no probabilístico y se evaluaron 36 tomografías Cone Beam con los índices CBCT-PAI, COPI y CBCT-ERI; los datos recolectados fueron analizados estadísticamente y se determinó que el índice CBCT-PAI identificó 91,7 % lesiones periapicales; el índice COPI, 72,2 % y el índice CBCT-ERI, 88,9 %. Asimismo, se aplicó la prueba x2 de Pearson y se determinó un valor de p=0,05. Por lo tanto, se concluyó que el diagnóstico de lesiones periapicales sobre tomografía computarizada Cone Beam puede presentar resultados similares cuando se evalúa con cualquiera de los índices CBCT-PAI, COPI o CBCT-ERI.

The use of Cone Beam Computed Tomography (CBCT) can favor the early diagnosis of apical periodontitis and influence its prognosis and treatment; however, there is no standardization among the indexes that determine the presence of periapical lesions in this radiological technique. For this reason, the aim of this study was to evaluate periapical lesions using three indices on CBCT. The study population consisted of all the CBCT scans performed in a Peruvian radiological center for one year, a non-probabilistic sampling was performed and 36 Cone Beam tomography's were evaluated with the CBCT-PAI, COPI and CBCT-ERI indexes; the data collected were analyzed statistically and it was determined that the CBCT-PAI index identified 91.7 % periapical lesions; the COPI index, 72.2 % and the CBCT-ERI index, 88.9 %. Likewise, Pearson's x2 test was applied and a value of p=0.05 was determined. Therefore, it was concluded that the diagnosis of periapical lesions on Cone Beam computed tomography can present similar results when evaluated with any of the CBCT-PAI, COPI or CBCT-ERI indexes.

Postoperative chronic pain in arthroplasty papillon-lefèvre syndrome: 17-year dental follow-up: case report / Síndrome de papillon-lefèvre: seguimiento dental de 17 años: reporte de caso

Introduction: The present report describes the case of a 12-year-old patient with 17-year follow-up who was previously diagnosed with Papillon-Lefèvre Syndrome (PLS), which is a rare autosomal recessive irregularity in the cathepsin C gene (CTSC) characterized by palmoplantar hyperkeratosis and premature loss of primary and permanent teeth. Case Report: A specific mutation in the c.203 T > G gene inducing loss of function leading to PLS was detected, as was a mutation in the HLA-DRB1*11 allele, which is associated with this syndrome. There is no consanguinity of the parents, and the siblings are entirely healthy. Early identification of the main characteristics of this syndrome is imperative. Accurate diagnosis by genetic analysis allows differential diagnoses and timely comprehensive dental treatment. Conclusions: Additionally, it allows consultation with a dermatologist to maintain or improve the quality of life of patients with this condition due to progressive worsening and severity of the main physical manifestations.

Incisor root length in individuals with and without anterior open bite: a comparative CBCT study

ABSTRACT Objective: This study aimed to compare the root length of maxillary and mandibular incisors between individuals with open bite versus matched individuals with adequate overbite. Methods: This comparative, matched and retrospective study included 48 cone beam computed tomographies (CBCTs) obtained at a university radiological center. Scans belonged to 24 individuals with open bite (overbite ≤ 0 mm) and 24 individuals with adequate overbite (controls). Both groups were matched by age, sex, malocclusion classification and skeletal characteristics (ANB and FMA angles). Root length of each maxillary and mandibular incisor was measured in millimeters (mm) in a sagittal section from a perpendicular line to the enamel cement junction until the root apex (384 length measurements were made). The means of root length in both groups were compared using t-tests. In addition, correlations between variables were evaluated with the Pearson correlation coefficient (α = 0.05). Results: In both groups, the root length of the upper central incisors was approximately 12 mm and the root length of the maxillary lateral incisors was approximately 13 mm (p˃ 0.05). Likewise, the root length of lower central incisors in both groups measured approximately 12 mm (p˃ 0.05). However, the mandibular lateral incisor roots of open bite patients were significantly longer than in the normal overbite patients (approximately 1 mm, p= 0.012 right side, p= 0.001 left side). Conclusions: Root length of maxillary incisors and central mandibular incisor is similar in individuals with or without open bite, but the mandibular lateral incisor roots in open bite patients were significantly longer than in the normal overbite patients.

RESUMO Objetivo: O presente estudo teve como objetivo comparar o comprimento radicular de incisivos superiores e inferiores em indivíduos com mordida aberta versus indivíduos com sobremordida normal. Método: Esse estudo comparativo e retrospectivo incluiu 48 tomografias computadorizadas de feixe cônico (TCFC) obtidas em um centro radiológico universitário. As tomografias foram realizadas em 24 indivíduos com mordida aberta (sobremordida ≤ 0 mm) e 24 indivíduos com sobremordida normal (controle). Ambos os grupos foram compatibilizados de acordo com a idade, sexo, má oclusão e padrão esquelético (ângulos ANB e FMA). O comprimento radicular de todos os incisivos superiores e inferiores foi medido em milímetros (mm) em um corte sagital, de uma linha perpendicular à junção cemento-esmalte até o ápice radicular (384 medidas de comprimento foram realizadas). A média de comprimento radicular em ambos os grupos foi comparada utilizando-se o teste t. Adicionalmente, correlações entre as variáveis foram avaliadas usando o coeficiente de correlação de Pearson (α = 0,05). Resultados: Em ambos os grupos, o comprimento radicular dos incisivos centrais superiores foi de, aproximadamente, 12 mm, e o comprimento radicular dos incisivos laterais superiores foi de, aproximadamente, 13 mm (p˃ 0,05). Da mesma forma, o comprimento radicular dos incisivos centrais inferiores, em ambos os grupos, obteve a medida de aproximadamente 12 mm (p>0,05). No entanto, o comprimento radicular dos incisivos laterais inferiores em indivíduos com mordida aberta foi significativamente maior em comparação aos pacientes com sobremordida normal (aproximadamente 1 mm, p=0,012 do lado direito, p=0,001 do lado esquerdo). Conclusões: O comprimento radicular de incisivos superiores e incisivos centrais inferiores foi similar em indivíduos com ou sem mordida aberta, mas o comprimento radicular de incisivos laterais inferiores em indivíduos com mordida aberta foi significativamente maior em comparação a pacientes com sobremordida normal.

RESUMEN Con el objetivo de determinar la asociación entre las condiciones de salud oral e higiene oral y el estado nutricional en niños usuarios de un establecimiento de salud en la región Huánuco se realizó un estudio transversal descriptivo en 118 niños que acudieron al control de crecimiento y desarrollo (CRED) del Puesto de Salud «La Esperanza¼. Las condiciones de salud e higiene oral fueron evaluados mediante los índices de placa bacteriana visible, higiene bucal simplificado, hemorragia simplificado e inflamación gingival. El estado nutricional se obtuvo del último control de CRED registrado en la historia clínica. La desnutrición aguda (DA) fue el estado nutricional más frecuente. Entre los niños con DA la proporción de inflamación gingival severa fue 60,3%, sangrado de encías 61,5%, presencia de placa dentobacteriana 59,3% e higiene oral deficiente 60,3%. Se evidencia una mayor afectación de la salud oral e higiene oral en niños con desnutrición, principalmente aguda.

ABSTRACT In order to determine the association between oral health and oral hygiene conditions and nutritional status in children using a health facility in the Huánuco region, a cross-sectional descriptive study was conducted in 118 children who attended the Growth and Development Control (CRED) of the health clinic "La Esperanza." Oral health and hygiene conditions were evaluated by visible bacterial plaque, simplified oral hygiene, simplified bleeding, and gingival inflammation indices. Nutritional status was obtained from the last CRED control recorded in the clinical history. Acute malnutrition (AM) was the most common nutritional status. Among children with AM, the proportion of severe gingival inflammation was 60.3%; gum bleeding, 61.5%; dentobacterial plaque presence, 59.3%; and poor oral hygiene, 60.3%. There is evidence of a greater impact of oral health and oral hygiene on children with malnutrition, mainly acute.

Efficiency of ODI and APDI of Kim's cephalometric analysis in a Latin American population with skeletal open bite

ABSTRACT Objective: The objective of this research was to demonstrate the efficiency of the overbite depth indicator (ODI) and the anteroposterior dysplasia indicator (APDI) from Kim's cephalometric analysis, regarding the determination of the vertical and sagittal patterns of Latin American individuals. Methods: Two hundred lateral cephalometric radiographs were selected and divided into four study groups, with 50 radiographs each, for carrying out a cross-sectional study. The control group included radiographs of balanced individuals, and the other three groups had lateral cephalometric radiographs of subjects with Class I, II and III malocclusions and with skeletal open bite. After the pilot test was performed to calibrate the investigator, the ODI and APDI were measured. Descriptive statistics were performed and the one-way ANOVA with post-hoc Tukey HSD, or Kruskal-Wallis and Mann-Whitney U-test were used. Also a multiple linear regression was employed. Results: Statistically significant differences were found for the ODI of all groups (p< 0.001), except between Class I group (65.87 ± 4.26) and Class II open bite group (67.19 ± 3.58), both with similar values to each other. For APDI, statistically significant differences were also found for all groups (p< 0.001). However, no statistically significant differences were found between the balanced group (83.18 ± 1.71) and Class I group with skeletal open bite (81.78 ± 2.69). Conclusions: ODI and APDI are reliable indicators to evaluate the sagittal and vertical patterns of an individual, demonstrating their efficiency when a Latin American population was evaluated.

RESUMO Objetivo: o objetivo desta pesquisa foi demonstrar a eficácia do indicador de profundidade da sobremordida (ODI) e do indicador de displasia anteroposterior (APDI) da análise cefalométrica de Kim, no que diz respeito à determinação dos padrões vertical e sagital em indivíduos latino-americanos. Métodos: duzentas telerradiografias em norma lateral foram selecionadas e divididas em quatro grupos, com 50 radiografias cada, para a realização desse estudo transversal. O grupo controle incluiu radiografias de indivíduos com oclusão normal, e os outros três grupos incluíram, respectivamente, radiografias de indivíduos com má oclusão de Classe I, Classe II e Classe III, com mordida aberta esquelética. Após a realização de um estudo piloto para calibração do investigador, fez-se a medição do ODI e do APDI. Foram realizadas estatísticas descritivas e utilizados os testes ANOVA de uma via com post-hoc HSD de Tukey, ou teste de Kruskal-Wallis e teste U de Mann-Whitney. Também foi realizada uma regressão linear múltipla. Resultados: foram encontradas diferenças estatisticamente significativas para o ODI entre todos os grupos (p< 0,001), exceto entre os grupos Classe I (65,87 ± 4,26) e Classe II com mordida aberta (67,19 ± 3,58), ambos com valores semelhantes entre si. Para o APDI, também foram encontradas diferenças estatisticamente significativas entre todos os grupos (p< 0,001). Entretanto, não foi encontrada nenhuma diferença estatisticamente significativa entre o grupo controle (83,19 ± 1,71) e o grupo Classe I com mordida aberta esquelética (81,78 ± 2,69). Conclusões: tanto o ODI quanto o APDI são indicadores confiáveis para se avaliar os padrões sagital e vertical de um indivíduo, tendo sua eficácia comprovada para uso na população latino-americana estudada.

Morphological variations of the maxillary sinus floor adjacent to periapical chronic injuries

Background: Today, there are several diagnostic methods to determine the exact size and nature of periapical lesions. Furthermore, there are studies that described thickening of the mucous membrane of the maxillary sinus (MS) in patients with periapical lesions and demonstrated a causal relation. Aims: This study aims to evaluate the morphological variations of the MS floor (MSF) adjacent to chronic periapical lesions in molars and premolars using cone-beam computed tomography (CBCT). Methods: Twenty-five CBCTs with periapical lesions adjacent to maxillary molars and premolars were evaluated. A total of 50 maxillary sinuses were analyzed (12 males and 13 women) taking into account density changes within the sinus cavity. The thickening of the sinus mucosa and the periapical lesions was measured in a caudal-cephalic direction. The axial and sagittal axis was taken as reference on the sagittal and coronal sections. Statistical Analysis: Chi-square, Fisher exact, and the Mann–Whitney tests were used in this study. Results: A significant association between the size of the periapical lesions (>4 mm) and the presence of MSF affectation was found on sagittal and coronal views (P < 0.001). No significant differences between the presence or absence of periapical lesions and the thickening of the sinus mucosa were found (P = 0.241). The presence of opacification on the MS had no direct associations with the periapical lesions. Conclusions: Maxillary sinus floor affectation was associated with chronic periapical lesions >4 mm. The opacification or thickening of the sinus mucosa was not related with the periapical lesions.

Objetivo: Determinar la reproducibilidad en el diagnóstico de los estadios de maduración esquelética según el método de Fishman en radiografías cárpales evaluados por odontólogos entrenados. Metodología: La población de estudio estuvo constituida por evaluaciones del diagnóstico carpal de 34 radiografías cárpales estandarizadas, realizadas por 4 observadores entrenados (3 especialistas en ortodoncia y un estudiante de último ciclo de odontología calibrado). Las mediciones se realizaron en tres momentos establecidos tiempo 1, tiempo 2 (a la semana del tiempo 1), tiempo 3 (al mes del tiempo 1). Haciendo un total de 102 diagnósticos por evaluador y un total de 408 diagnósticos entre los 4 evaluadores. Se evaluaron 10 radiografías por día para eliminar el efecto memoria de los observadores hasta terminar con las 34 radiografías. Resultados: Los resultados de la evaluación de la concordancia del diagnóstico de maduración esquelética entre los cuatro operadores en los tres tiempos evaluados, muestran una correlación de Spearman con valores superiores a 0.8, consideradas correlaciones muy buenas. En la evaluación de la concordancia intra operador en los 3 tiempos evaluados se encontró concordancias buenas y moderadas, y en la evaluación de la concordancia inter operador en los 3 tiempos se encontró concordancias buenas, el valor de concordancia intra operador más alto fue 0.800 y la concordancia inter operador más alta fue de 0.507. Conclusiones: La concordancia del diagnóstico en el método de maduración esquelética de Fishman evaluado por cuatro clínicos de odontología un mes después de su primer diagnóstico fue moderada a alta.

Björk-Jarabak cephalometric analysis on CBCT synthesized cephalograms with different dentofacial sagittal skeletal patterns

OBJECTIVE: The objective of this study was to evaluate the Björk and Jabarak cephalometric analysis generated from cone-beam computed tomography (CBCT) synthesized lateral cephalograms in adults with different sagittal skeletal patterns. METHODS: The sample consisted of 46 CBCT synthesized cephalograms obtained from patients between 16 and 40 years old. A Björk and Jarabak cephalometric analysis among different sagittal skeletal classes was performed. Analysis of variance (ANOVA), multiple range test of Tukey, Kruskal-Wallis test, and independent t-test were used as appropriate. RESULTS: In comparison to the standard values: Skeletal Class III had increased gonial and superior gonial angles (P < 0.001). This trend was also evident when sex was considered. For Class I males, the sella angle was decreased (P = 0.041), articular angle increased (P = 0.027) and gonial angle decreased (P = 0.002); whereas for Class III males, the gonial angle was increased (P = 0.012). For Class I females, the articular angle was increased (P = 0.029) and the gonial angle decreased (P = 0.004). Björk's sum and Björk and Jabarak polygon sum showed no significant differences. The facial biotype presented in the three sagittal classes was mainly hypodivergent and neutral. CONCLUSIONS: In this sample, skeletal Class III malocclusion was strongly differentiated from the other sagittal classes, specifically in the mandible, as calculated through Björk and Jarabak analysis. .

CONCLUSÕES: na amostra do presente estudo, a má oclusão esquelética de Classe III foi fortemente diferenciada de outras classes sagitais, ...

Concordancia entre estadíos de calcificación dentaria y maduración esquelética en niños y adolescentes de una localidad peruana / Concordance between dental calcification phases and skeletal maturation process in children and adolescents from a peruvian town

El propósito de la investigación fue determinar la concordancia entre los estadíos de calcificación dentaria de caninos, premolares y segundas molares mandibulares según el método de Demirjian y los estadíos de maduración esquelética según el método de Fishman. La muestra estuvo conformada por 182 niños y adolescentes de 9 a 16 años de edad de una localidad peruana, a los cuáles se les tomaron radiografías carpales y periapicales, todas registradas en el mismo momento. Los grados de correlación fueron altos para todas las piezas dentarias en ambos sexos, para el sexo masculino fueron entre r=0,82 y 0,90; siendo la segunda molar inferior la que tuvo la correlación más alta, para el sexo femenino los rangos fueron entre r=0,84 y 0,93; siendo la correlación más alta la del canino inferior. La concordancia entre los estadíos de calcificación dentaria de caninos, premolares y segundas molares mandibulares y los estadíos de maduración esquelética es diferente para cada una de las piezas dentarias evaluadas, siendo el canino el diente con mayor concordancia y mejor utilidad clínica. Se concluye que la calcificación dentaria puede ser clínicamente útil para evaluar los estadíos de maduración esquelética.

The purpose of this investigation was to determine the concordance between the mandibular canine, premolar, and second molar dental calcification phases according to the Demirjian method and the maturity skeletal phases according to the Fishman method in 182 children and adolescents 9 to 16 years old of a peruvian town, to which carpal and periapical radiographs were taken and registered at the same time. The correlation levels were high for all teeth in both sexes, for males were r=0.822 to 0.906, being the lower second molar which had the highest correlation for females were r=0.843 to 0.934, with a higher correlation with the lower canine. Concordance between dental calcification phases in mandibular canine, premolar and second molar and the skeletal maturity phases is different in each one of the assessed teeth, being the canine the tooth with higher concordance and clinical usefulness. Finally we conclude that dental calcification can be clinically useful to assess the skeletal maturity phases.
