Abstract
Given the limited comprehension of the indigenous oral health profile, this study proposed to understand the self-perception of oral health of this population group. This study aimed to verify the association of oral health's self-perceived impact on daily living with sociodemographic and oral health characteristics among indigenous people aged 10 to 14 years of the Xukuru do Ororubá ethnic group, in Pesqueira (PE), Brazil. This is a cross-sectional study conducted from January to March 2010, involving oral examinations and questionnaires applied to 233 indigenous belonging to the age group. Using the latent class analysis model, the variable "oral health impact" was created and applied to simple and multiple logistic regression models. The results pointed out that villages with the highest mean of households and indigenous people with caries experience evidenced worse self-perception, increasing the "oral health impact" 2.37 and 3.95 times, respectively. The Latent Class Analysis was an excellent strategy for understanding the self-perception of indigenous oral health and its relationship with associated factors.
Highlights
The understanding of the oral health profile of indigenous people is still limited
The few available studies reinforce that in different countries[1,2,3], this population group faces worse oral health conditions when compared to non-indigenous people
Regarding self-perceived health, a subjective measure recommended by the World Health Organization (WHO) to verify the health of the population, while not replacing the clinical examination of the patient, allows a closer look at the real condition of the individual quickly, affordably and economically[4]
Summary
The understanding of the oral health profile of indigenous people is still limited. The few available studies reinforce that in different countries[1,2,3], this population group faces worse oral health conditions when compared to non-indigenous people.Regarding self-perceived health, a subjective measure recommended by the World Health Organization (WHO) to verify the health of the population, while not replacing the clinical examination of the patient, allows a closer look at the real condition of the individual quickly, affordably and economically[4].In oral health, self-perception is a vital measurement tool that can be used as an indicator of treatment needs or to estimate the effect of oral conditions in daily living, as well as to evaluate and monitor improvements in the oral health status of society[5,6].The association of negative self-perception of oral health with oral clinical conditions (presence of oral disease, tissue damage, pain, functional and aesthetic impairment)[7], unfavorable demographic and behavioral psychosocial and socioeconomic factors[8] is well established in the literature, making subjective assessment a critical contribution in the identification of vulnerable groups of population that require sophisticated and often personalized interventions[9].A study by Amarasena et al.[10] investigated oral health behaviors and perceptions of 181 Australian natives aged 22-74 years, comparing their data with the general Australian population. The few available studies reinforce that in different countries[1,2,3], this population group faces worse oral health conditions when compared to non-indigenous people. The association of negative self-perception of oral health with oral clinical conditions (presence of oral disease, tissue damage, pain, functional and aesthetic impairment)[7], unfavorable demographic and behavioral psychosocial and socioeconomic factors[8] is well established in the literature, making subjective assessment a critical contribution in the identification of vulnerable groups of population that require sophisticated and often personalized interventions[9]. It was found that the indigenous population has less frequent dental visits Their visits are motivated by oral problems, and among natives, it is more common to postpone dental treatment due to high costs. The perception of the need for treatment, pain, aesthetic discomfort and the report of food intake due to oral problems was higher among natives
