RESUMEN
Introducción: El análisis factorial exploratorio se usa comúnmente para evaluar la validez de la estructura interna en escalas de calidad de vida de la salud bucal. Empero, existen discusiones sobre usar indiscriminadamente el análisis de componentes principales para extraer los factores. Objetivo: Comparar los resultados de la validez basada en la estructura interna del Parental-Caregiver Perception Questionnaire - 8 ítems mediante análisis factorial exploratorio utilizando el análisis de componentes principales y otros métodos de extracción de factores. Métodos: Se realizó una revisión preliminar de la literatura para examinar el uso del análisis factorial exploratorio y sus métodos en la validación de escalas de calidad de vida relacionada con la salud bucal y se ejecutó un análisis factorial con datos de la validación del instrumento Parental-Caregiver Perception Questionnaire - versión 8, para comparar los valores de las comunalidades y las cargas factoriales de las soluciones extraídas. Resultados: La mayoría de los artículos que exploran la estructura factorial reportan el análisis de componentes principales como método de extracción y Varimax en la rotación. La información sobre los criterios para utilizar estos métodos fue insuficiente. En el análisis factorial se obtuvo que, las cargas factoriales, las comunidades y el número de factores extraídos fueron superiores con el método componentes principales. Conclusión: Usar el análisis de componentes principales como método de extracción de factores acarrea el riesgo de obtener una dimensionalidad sobreestimada en la evaluación de la validez basada en la estructura interna de las escalas de calidad de vida relacionada con la salud bucal.
Introduction: Exploratory factor analysis is commonly used to assess the validity of the internal structure in oral health quality of life scales. However, there are discussions about using principal component analysis indiscriminately to extract the factors. Objective: To compare the results of the internal structure-based validity of the Parental-Caregiver Perception Questionnaire - 8 items by exploratory factor analysis using principal component analysis and other factor estimation extraction methods. Methods: A literature review was conducted to examine the use of exploratory factor analysis and its methods in validating oral health-related quality of life scales, and a factor analysis was performed with validation data from the Parental-Caregiver Perception instrument. Questionnaire - version 8 to compare the values of the communalities and the factor loads of the solutions extracted. Results: Most of the articles that explored the factorial structure reported the analysis of principal components as extraction method and Varimax in rotation. Information on the criteria for using these methods was insufficient. In the factorial analysis, it was obtained that the factorial loads, the communities and the number of extracted factors were higher with the principals component method. Conclusion: Using principal components analysis as a factor extraction method carries the risk of obtaining an overestimated dimensionality in the validity assessment based on the internal structure of oral health-related quality of life scales.
RESUMEN
Introduction: Hypersensitivity, altered dental appearance and fractures are common problems in molar incisor hypomineralization that generate functional and socio-emotional problems. Objective: to evaluate the effect of MIH on oral health-related quality of life in children and adolescents. Materials and methods: A systematic bibliographic search was carried out in electronic databases (Pubmed, Epistemonikos, Dentistry & Oral Sciences Source and Virtual Health Library). Observational studies in English or Spanish conducted between 2016-2022 that evaluated the quality of life of children and adolescents with molar incisor hypomineralization were identified. Most studies were of good methodological quality. Results: Of 96 identified studies, thirteen were included in the synthesis. The most frequent diagnostic criterion for hypomineralization of molar incisors was the index of the European Academy of Pediatric Dentistry and nine studies reported the severity of the disease. The most widely used scale to measure quality of life was the Child Perception Questionnaire (CPQ). According to the children's perception, the most affected dimensions were "Oral Symptoms" and "Emotional Well-Being", according to the parents they were "Oral Symptoms" and "Functional Limitations". Girls with molar incisor hypomineralization had worse oral health-related quality of life. Conclusions: The negative effect of molar incisor hypomineralization on children's oral health-related quality of life seems to vary between the perception of parents and children.
RESUMEN
Objetivo: Determinar el efecto de la severidad de la periodontitis en la calidad de vida relacionada con la salud bucal. Métodos: Estudio transversal que reclutó una muestra de 229 adultos con periodontitis leve, moderada y severa. La calidad de vida se midió con el Perfil de Impacto en la Salud Oral (OHIP-14). Resultados: Se encontró que los sujetos con periodontitis moderada tenían peor OHRQoL (40,2 %) en comparación con aquellos con periodontitis leve (31,8 %) y grave (28 %). Se encontraron diferencias estadísticamente significativas entre los grupos en cuanto a limitación funcional (p=0,004), dolor físico (p=0,004), incapacidad física (p=0,015), incapacidad psicológica (p=0,01) e incapacidad social (p= 0,004). Conclusiones: las dimensiones discapacidad psicológica y malestar psicológico se vieron afectadas de manera similar independientemente del estado periodontal. En sujetos con periodontitis severa hubo mayor afectación en limitación funcional e incapacidad física .
Objetivo: Determinar o efeito da gravidade da periodontite na qualidade de vida relacionada à saúde bucal. Métodos: Estudo transversal que recrutou uma amostra de 229 adultos com periodontite leve, moderada e grave. A qualidade de vida foi medida com o Oral Health Impact Profile (OHIP-14). Resultados: Indivíduos com periodontite moderada apresentaram pior QVRSO (40,2%) em comparação com aqueles com periodontite leve (31,8%) e grave (28%). Foram encontradas diferenças estatisticamente significativas entre os grupos quanto à limitação funcional (p=0,004), dor física (p=0,004), incapacidade física (p=0,015), incapacidade psicológica (p=0,01) e incapacidade social (p= 0,004). Conclusões: As dimensões deficiência psicológica e sofrimento psíquico foram afetadas de forma semelhante, independentemente do estado periodontal. Nos indivíduos com periodontite severa houve maior envolvimento na limitação funcional e incapacidade física.
Objective: To determine the effect of the severity of periodontitis on quality of life related to oral health. Methods: Cross-sectional study that recruited a sample of 229 adults with mild, moderate and severe periodontitis. Quality of life was measured with the Oral Health Impact Profile (OHIP-14). Results: Subjects with moderate periodontitis were found to have worse OHRQoL (40.2%) compared to those with mild (31.8%) and severe (28%) periodontitis. Statistically significant differences were found between the groups regarding functional limitation (p=0.004), physical pain (p=0.004), physical disability (p=0.015), psychological disability (p=0.01) and social disability (p= 0.004). Conclusions: the psychological disability and psychological distress dimensions were similarly affected regardless of periodontal status. In subjects with severe periodontitis there was greater involvement in functional limitation and physical disability.
