Impact of Mobile Dental Clinics on the Quality of Life of Children

ABSTRACT

Objective:

To evaluate the impact of mobile dental clinics on the oral health-related quality of life (OHRQL) of children.

Material and Methods:

A longitudinal epidemiological study was conducted with participants from seven mobile dental clinics carried out between May 2019 and January 2020 by the NGO Missão Sorrisos. Parents and children who attended the program had their sociodemographic data collected. Both completed the Scale of Oral Health 5 (SOHO-5) self-reported questionnaire before treatment and again 30 days after treatment.

Results:

The improvement in the children's oral health after treatment at the mobile clinics is reflected in the pre-and post-treatment medians measured by the SOHO-5 total score from the children's own reports from the parents' reports. The procedures performed were effective in reducing pain and difficulties in eating, drinking, and sleeping. An improvement in the perception of the children's appearance and self-confidence was reported, both from the perspective of the parents/guardians and the children themselves. The chance of improvement in the perception of the children’s oral health was greater for parents (OR=5.96; CI95%: 1.32-26.84) and children (OR=5.76; CI95%: 1.28-25.95) from families whose main caregiver was not professionally active at the time of the study.

Conclusion:

The mobile dental clinics had a positive impact on the OHRQL of children from the perspective of the participants of the study.

Introduction

Dental caries in both primary and permanent teeth are still a significant health problem in most countries and were among the ten diseases with the highest incidence in 195 countries and territories between 1990 and 2016 [1[1] Corrêa-Faria P, Daher A, Freire MDCM, de Abreu MHNG, Bönecker M, Costa LR.

Literature shows that caries in advanced stages if left untreated, can lead to aesthetic, functional, and psychological problems that impact daily life and affect the child's growth, weight gain, self-confidence, and socialization. Furthermore, they can affect the learning abilities and daily activities of children and parents [10[10] World Health Organization. A conceptual framework for action on social determinants of health.

Material and Methods

Type and Place of Study

An epidemiological, longitudinal study of a quantitative nature was conducted in Goiânia, the capital of the state of Goiás, located in the Brazilian Midwest, which has a Human Development Index (HDI) of 0.7998. The study was approved by the Ethics Committee for Research in Human under CAEE 29383020.8.0000.5378. All the children who participated in the study signed an Assent Form, and their direct guardians signed a Free and Informed Consent Form.

The socially-funded NGO Missão Sorrisos was created in June 2018 and provides free dental care to the population, treating adults and children who need preventive, curative, and or rehabilitative dental treatment, which is carried out by volunteer specialists. The mobile clinics are carried out every month in the most vulnerable regions of the city.

In all, seven monthly mobile clinics were carried out between May 2019 and January 2020, on Saturdays, from 8:00 am to 6:00 pm, and pediatric clinical care was performed by a single specialist.

Sample Characterization and Inclusion and Exclusion Criteria

The convenience sample consisted of all children between 4 and 12 years old who attended the seven mobile clinic groups carried out in the period and who had dental caries at the dentin level, a need for extractions, and/or who complained of pain in the anamnesis. To be included in the study, the direct guardians of the treated children had to agree to participate and provide documents proving their familial link with the child, ensuring accuracy in the answers to the questionnaire. The children had to be able to answer the questionnaire without the presence of their parents.

Experimental Design

After training, during screening, two professionals invited the participants of the mobile clinics to participate in the study and were responsible for applying the questionnaires through interviews.

The questionnaire was applied among those who agreed to participate, and the children were referred to for dental treatment by the researcher. The questionnaire included questions about the sociodemographic characteristics of the children and their parents/guardians, as well as the Scale of Oral Health Outcomes for 5-year-old children (SOHO-5), which was translated according to transcultural use in Brazil. SOHO-5 consists of the child's self-report (SOHO-5c) and the secondary parent’s report (SOHO-5p) on the child's OHRQL, each of which is structurally composed of seven items, six of which have similar content in the child and parent versions [5[5] Abanto J, Tsakos G, Paiva SM, Goursand D, Raggio DP, Bönecker M. Cross-cultural adaptation and psychometric properties of the Brazilian version of the scale of oral health outcomes for 5-year-old children (SOHO-5). Health Qual Life Outcomes 2013; 11:16. https://doi.org/10.1186/1477-7525-11-16

,22[22] Tsakos G, Blair YI, Yusuf H, Wright W, Watt RG, Macpherson LM. Developing a new self-reported scale of oral health outcomes for 5-year-old children (SOHO-5). Health Qual Life Outcomes 2012; 10:62. https://doi.org/10.1186/1477-7525-10-62
https://doi.org/10.1186/1477-7525-10-62...
].

The seven items in the SOHO-5c version address difficulty eating; drinking, speaking; playing, and sleeping, as well as avoiding smiling due to pain and appearance. Each item has three response options: no = 0; a little = 1; and a lot = 2 [22[22] Tsakos G, Blair YI, Yusuf H, Wright W, Watt RG, Macpherson LM. Developing a new self-reported scale of oral health outcomes for 5-year-old children (SOHO-5). Health Qual Life Outcomes 2012; 10:62. https://doi.org/10.1186/1477-7525-10-62
https://doi.org/10.1186/1477-7525-10-62...
]. The SOHO-5p version addresses the parent/guardian's perception of the child's difficulty eating, speaking, playing, sleeping, and avoiding smiling due to pain and appearance, and includes a question about whether the child's self-confidence is affected by their teeth.

Thirty days after having each mobile dental clinic, the SOHO-5 versions were reapplied by phone call, by a trained professional. To avoid interference from the participants, the children were invited to answer first, with their parents asked to wait some distance away, and in silence, and to come to the phone only when it was their turn to answer questions. When the child was not at home, the call was made on another occasion.

Figure 1 details the steps of the experimental sequence in each mobile dental clinic:

Design and experimental sequence.

Data Analysis

The total score for each of the SOHO-5 versions was calculated from the sum of the answers. In the parental version, the response options were grouped into three categories (no = 0; a little = 1; moderate/a lot = 2) [23[23] Paiva CR, Alves Filho AO, Medina PO, Zacarias Filho RP, Hanan SA.

https://doi.org/10.1111/ipd.12081...
]. In the present study, the cutoff point was the median calculated for both versions, with scores higher than the median indicative of a greater impact on the child's OHRQL.

First, a descriptive analysis of the data was performed. Absolute and relative frequencies, median, minimum and maximum values were used for this purpose. The analysis of agreement between the answers in the initial and final applications of each question of the SOHO-5 instrument was performed using the Bowker symmetry test.

Comparisons between the overall results at the beginning and end of the study were made using the nonparametric Wilcoxon test for paired samples. Next, simple logistic regression models were estimated between each sociodemographic variable and the scores of perception of parents and children about the improvement in oral health after treatment at the mobile clinic. Variables with p<0.20 in this crude analysis were examined in multiple models, with those with p≤0.05 remaining in the final model. The odds ratios were estimated from the models with their respective 95% confidence intervals. The fit of the models was analyzed using the Akaike Information Criterion (AIC). Analyzes were performed using the R program with a significance level of 5%.

Results

A total of 325 children participated in pediatric dental care as part of the mobile clinics, of whom 143 were enrolled in the study, with a mean age of 7.8 ± 2.2 years, and met the inclusion and exclusion criteria. In addition to prophylaxis and the topical application of fluoride, the following invasive procedures were performed on these children: 43 anterior restorations, 284 posterior restorations, 99 extractions, eight endodontic procedures on the deciduous teeth, and seven expectant treatment procedures.

Table 1 shows the sociodemographic characteristics of the parents/guardians of the children. Most are female, white, aged between 25 and 35 years old, and have completed elementary school. Also, most had up to three children, were working, received one to two times the minimum wage (MW), which was R$1,045.00 (one thousand and forty-five reais) and had two or more dependents on this income.

Table 1
Descriptive analysis of the sociodemographic variables of the parents/guardians.

From the versions of the SOHO instrument, in the assessment before receiving treatment at the mobile clinic, the highest score reported was 9 in the child's self-report and 7 in the parental version, with the mean total score being 1.4 ( ±1.7) for SOHO-5c and 1.7 (±1.9) for SOHO-5p. Thirty days after treatment at the mobile clinic, the highest score for the self-report of the child and the guardian was 2 and 3, respectively, with the mean total measured scores being 0.0 (±0.2) for SOHO- 5c and 0.2 (±0.5) for SOHO-5p. Table 2 shows a significant decrease in the median of the SOHO-5 total score and a consequent improvement in the perception of oral health among parents/guardians and children (p<0.05).

Table 2
Median of the total scores for parents/guardians and children, from the SOHO-5 instrument, before and after treatment at the mobile dental clinic.

Table 3 shows the results of the parents' answers regarding the perception of their child's oral health in each SOHO-5 question, before and after the child's treatment at the mobile clinic. For 43.4% and 3.5% of the parents, the child had little and reasonable difficulty eating, respectively, and no longer had any difficulties after treatment (p<0.05). Furthermore, the various difficulties of the children were felt more by parents/guardians before treatment at the mobile clinic care, while there was a major improvement in this perception after treatment.

Table 3
Distribution of responses from parents/guardians in the questions of the SOHO-5p instrument before and after treatment of their children at the mobile dental clinic.

Table 4 shows the results of the children's responses before and after treatment. It was found that 71 children had difficulty eating, and 68 of them (95.8%) perceived improvement after treatment (p<0.05). Difficulty speaking and playing was perceived by 16 children, and all perceived improvement (100.0%). Also, 25, 27, 32, and 45 children had difficulty sleeping, smile/pain, difficulty smiling/appearance, and difficulty drinking, respectively, and all experienced improvement after treatment. Children also showed significant reductions in their felt difficulties after participating in the mobile clinics.

Table 4
Distribution of children's responses to the questions of the SOHO -5c instrument in the period before and after assistance by the mobile dental clinic.

Table 5 shows the results of the associations. Only the professional activity of the parents influenced the perception of improved oral health after participation in the mobile clinics. Parents who were not working were 5.96 (IC95%: 1, 32-26.84) times more likely to notice an improvement in the child's oral health after treatment than working parents (p<0.05), and children born to parents who were not working were 5.76 (IC95%: 1.28-25.95) times more likely to notice an improvement in their oral health after treatment than children of working parents (p<0.05).

Discussion

Dental treatment carried out at the mobile dental clinic significantly improved children's OHRQL in both the reports of the parents and children and this perception was more likely to be observed in families where the main caregiver did not work outside the home.

Oral health problems, especially those related to dental caries can affect children's daily lives. The assessment of the impact of measures that can mitigate the suffering of children and positively impact their OHRQL has been growing around the world [1[1] Corrêa-Faria P, Daher A, Freire MDCM, de Abreu MHNG, Bönecker M, Costa LR.

]. Notwithstanding such advances, the present study is, to our knowledge, the first to demonstrate the short-term effects on OHRQL in children treated at mobile dental clinics.

The children included in the present study had lesions at the tooth level, which justifies the fact that the most performed invasive procedures were restorations, followed by tooth extractions. The presence of untreated caries can significantly affect well-being in the act of eating, causing discomfort and modifying eating patterns [27[27] Bonecker M. Como as pesquisas de excelência em Qualidade de vida relacionada à saúde bucal podem contribuir para a prática clínica? Rev Assoc Paul Cir Dent 2014; 68(3):220-1.

]. Although a previous study has shown that traditional and well-executed pediatric dental care has a positive effect on children's OHRQL [24[24] Abanto J, Tsakos G, Paiva SM, Raggio DP, Celiberti P, Bonecker M. Agreement between children aged 5-6 years and their mothers in rating child oral health-related quality of life. Int J Paediatr Dent 2014; 24(5):373-9. https://doi.org/10.1111/ipd.12081
https://doi.org/10.1111/ipd.12081...
], this phenomenon was also observed at the mobile clinics in the present study, where care is provided as the result of a need for treatment.

There is evidence of an association between caries and a worse OHRQL in the perception of children and their parents [16[16] Nóbrega AVD, Moura LFAD, Andrade NS, Lima CCB, Dourado DG, Lima MDM.

], but it has also been reported that families facing greater socioeconomic disadvantages may report a lower impact on quality of life at the same level of experience of caries [31[31] Biazevic MG, Rissotto RR, Michel-Crosato E, Mendes LA, Mendes MO. Relationship between oral health and its impact on quality of life among adolescents. Braz Oral Res 2008; 22(1):36-42. https://doi.org/10.1590/s1806-83242008000100007
https://doi.org/10.1590/s1806-8324200800...
], which may be a justification for the low pre-study SOHO-5 mean values found in the present study. In general, OHRQL improved in 65% of children and 64.3% of parents/guardians, which is consistent with previous results [32[32] Chaffee BW, Rodrigues PH, Kramer PF, Vítolo MR, Feldens CA. Oral health-related quality-of-life scores differ by socioeconomic status and caries experience. Community Dent Oral Epidemiol 2017; 45(3):216-24. https://doi.org/10.1111/cdoe.12279
https://doi.org/10.1111/cdoe.12279...
], and shows agreement between parent and child responses, as both perceived and reported an improvement in QoL after dental treatment in nontraditional contexts, in a school context, and in a mobile dental clinic.

Mobile dental clinics have emerged as an effective method of alleviating suffering and restoring the OHRQL of children such as those in the present study. In Brazil, one-fifth of Basic Health Units do not provide dental care to children [33[33] Mendonça JGA. Impacto do tratamento odontológico na qualidade de vida de um grupo de escolares brasileiros. [dissertation on the Internet. Brasília: Universidade de Brasília; 2017. Available from: https://repositorio.unb.br/bitstream/10482/31811/1/2017_JordannaGuedesAmorimMendon%C3%A7a.pdf [Accessed on November 12, 2017. [In Portuguese.
https://repositorio.unb.br/bitstream/104...
]. More specifically, in the state of Goiás, even though an increase in population coverage of oral health has been observed, the access of the most vulnerable populations to these services has not increased proportionately [34[34] Essvein G, Baumgarten A, Rech RS, Hilgert JB, Neves M. Dental care for early childhood in Brazil: from the public policy to evidence. Rev Saude Publica 2019; 53:15. https://doi.org/10.11606/S1518-8787.2019053000540
https://doi.org/10.11606/S1518-8787.2019...
]. Considering that a single pediatric dental rehabilitation in Brazil costs an average of R$150,00, according to the Regional Council of Dentistry/Goiás (RCD-GO) and the Brazilian Dental Association/Goiás (BDA-GO), treating the rehabilitation needs of the studied group would certainly strain the budgets of most families included in the present study, whose average income is 1 to 2 minimum wages (MW = R$ 1,045.00).

Literature has shown that black (Afro-Brazilian) and brown (mixed ethnicity) children have reported worse OHRQL when assessed by SOHO-c [34[34] Essvein G, Baumgarten A, Rech RS, Hilgert JB, Neves M. Dental care for early childhood in Brazil: from the public policy to evidence. Rev Saude Publica 2019; 53:15. https://doi.org/10.11606/S1518-8787.2019053000540
https://doi.org/10.11606/S1518-8787.2019...
], although, in the present study, no association with skin color was found, probably due to the fact that the predominance of families self-classified as white.

A previous study has argued that parents who work outside the home, because they have less daily contact with their children, may not have the perfect overview of their children's OHRQL and, therefore, provide information that differs from that which the children themselves provide [35[35] Tavares PCF, Almeida ETS. Primary care in oral health in the state of Goiás from 2001 to 2013. Com Ciências Saúde 2017; 28(2):226‑33 https://doi.org/10.51723/ccs.v28i02.233.
https://doi.org/10.51723/ccs.v28i02.233...
]. This may help to explain the finding of the present study that parents/guardians who did not work outside the home were more likely to notice an improvement in OHRQL after treatment at the mobile dental clinics; this suggests that parents/guardians who are closer to their children notice behaviors they would not notice if they worked outside the home [36[36] Abanto J, Panico C, Bönecker M, Frazão P. Impact of demographic and clinical variables on the oral health-related quality of life among five-year-old children: a population-based study using self-reports. Int J Paediatr Dent 2018; 28(1):43-51. https://doi.org/10.1111/ipd.12300
https://doi.org/10.1111/ipd.12300...
]. The time that parents, especially women (who made up the majority of the sample in the present study), manage to spend with their children is important not only for getting to know the child [36[36] Abanto J, Panico C, Bönecker M, Frazão P. Impact of demographic and clinical variables on the oral health-related quality of life among five-year-old children: a population-based study using self-reports. Int J Paediatr Dent 2018; 28(1):43-51. https://doi.org/10.1111/ipd.12300
https://doi.org/10.1111/ipd.12300...
] but also for the development of healthy oral health behaviors in them [37[37] Castilho AR, Mialhe FL, Barbosa Tde S, Puppin-Rontani RM. Influence of family environment on children's oral health: a systematic review. J Pediatr 2013; 89(2):116-23. https://doi.org/10.1016/j.jped.2013.03.014
https://doi.org/10.1016/j.jped.2013.03.0...
,38[38] Poutanen R, Lahti S, Tolvanen M, Hausen H. Parental influence on children's oral health-related behavior. Acta Odontol Scand 2006; 64(5):286-92. https://doi.org/10.1080/00016350600714498
https://doi.org/10.1080/0001635060071449...
]. In the same way, children of parents/guardians who did not work outside the home were also more likely to perceive the impact of the treatment carried out at the mobile clinic on their OHRQL, perhaps because the adults help the children notice the differences in their daily activities.

Due to the nature of the present study, it is possible that a feeling of gratitude contributed to the responses, which indicated an improvement in the OHRQL of children 30 days aftercare. However, the training of professionals responsible for the interviews, and their non-active participation in the clinical care carried out at the mobile clinic is likely to have alleviated this bias. It is also worth noting that the final assessment was conducted by telephone, which would encourage a negative response in relation to the improvement in OHRQL, as it is easier for the respondent to deny this improvement over the phone than in person. The longitudinal design of the present study, the careful selection of the sample, and the use of SOHO -5 in its two versions give the study adequate internal validity to assess the effect of the mobile clinics on OHRQL in the two phases of the study, thus mitigating the differences between the perceptions of parents and children found in previous studies which also consider the presence of advanced lesions as an inclusion criterion [39[39] Nascimento A, Silva HN, Fonseca de Brito OF, Barreira A. Patients satisfaction in Dental School Clinics of the Federal University of Pernambuco and associated factors. Rev UPF 2020; 25(1):66-73. https://doi.org/10.5335/rfo.v25i1.10639
https://doi.org/10.5335/rfo.v25i1.10639...
].

The present study is limited when it comes to extrapolating the results to the general population. However, it is important to show that for the vulnerable population that receives treatment from mobile health clinics, the impact on QoL is positive, and the human and social investment needed to maintain them in this post-pandemic era is valid.

Conclusion

Pediatric dental care provided by mobile dental clinics was effective at alleviating factors that cause suffering and, therefore, affect the OHRQL of children in vulnerable conditions, both in their own perception and in the perception of their parents/guardians. It was to be expected that the present study would efficiently reach its goals, as the assistance of trained professionals with quality material resources is an undeniable advantage to the recipients. However, other aspects are worth mentioning, such as the mobilization of a care strategy for the population, rather than the opposite; the quick response to the oral health needs of the volunteers; and the short-term relief of suffering (30 days), which efficiently meets the related demands.

Nevertheless, we recognize that no matter how efficiently the mobile dental clinic format meets these demands, several obstacles must be overcome to value and strengthen public dental care as provided for by the national oral health policy, ensuring access to health in a universal, equitable, and integral manner for all.
