Severe traumatic dental injuries and oral health related quality of life of preschool children

Traumatismos dentários severos e qualidade de vida relacionada à saúde bucal de crianças pré-escolares

ABSTRACT

Objective:

The aim of this study was to investigate the impact of severe traumatic dental injuries on the Oral Health related Quality of Life (OHRQoL) of preschool children.

Methods:

This cross-sectional study was conducted with children aged 2 to 5 years and their mothers, in Pelotas/ Brazil Southern. The Early Childhood Oral Health Impact Scale (ECOHIS) was applied to assess the perception of mothers about children’s OHRQoL. Oral examination included dental trauma, categorized as absent/mild (enamel fracture only) or severe, the number of decayed, missing or restored primary teeth (dmft), and presence of anterior open bite. The impact of severe dental trauma on OHRQoL was evaluated using logistic regression analysis (P<0.05).

Results:

A total of 599 preschool children were included and 7.4% had severe dental trauma. Of these 73.3% showed negative impact on OHRQoL (p= 0.044). After adjustments, children with severe dental trauma had an impact in OHRQoL 110% higher than those without/with mild trauma (OR: 2.10, 95% CI 1.01-4.35). Severe dental injuries caused negative impact on the oral symptoms (OR: 2.13, 95% CI 1.10-4.14), psychological (OR: 2.13, 95% CI 1.10-4.13) and family function (OR: 2.79, 95% CI 1.17-6.61) domains.

Conclusion:

The presence of severe dental trauma impacts the OHRQoL of preschool children and their families.

INTRODUCTION

Traumatic dental injuries (TDI) are the second most frequent reason for pediatric dental consultation, after dental caries. During early life, children are particularly vulnerable to these injuries [1] and the occurrence of TDI may result in pain, aesthetic and functional dysfunctions, with possible psychological repercussions [2]. However, the impact of TDI in primary dentition on children oral health-related quality of life is controversial. Whereas some studies have found that children presenting TDI had impaired oral health-related quality of life (OHRQoL) [3-5], and that TDI can cause a negative impact on the family function, including work absenteeism by parents [4], other studies have showed that the presence of this condition does not impair OHRQoL [6-8]. The possible impact on OHRQoL is an important indicator to define priorities in public health. Thus, it is important to evaluate factors associated with oral health perception.

A recent study has showed that enamel fracture does not impact on OHRQoL [9]. While enamel fracture is the most common injury, it may go unnoticed, unlike more severe injuries that require treatment or follow-up examinations [10]. Viegas et al. [11] found that the OHRQoL of the children and their families was influenced by the parental report of the occurrence of TDI, but not by the presence of TDI detected in clinical examination, assessed using Andreasen criteria. The study of Abanto et al. [12] showed that TDI, diagnosed using Glendor criteria, caused impact on some items of the family impact scale. The authors also detect that children with complicated injuries presented higher scores on OHRQoL than children with uncomplicated injuries or no injury. Kramer et al. [2] adopted Andreasen criteria to diagnose dental trauma and found that children with the presence of at least one type of trauma presented higher impact on OHRQoL. Thus, results vary according to the population studied, the criteria used to diagnose TDI and the level of severity of the injuries included

Since traumatic dental injuries can range from enamel fracture only to tooth loss, severity of the injury should be taken into account while evaluating the possible consequences of dental trauma. This study aimed to investigate the impact of TDI on the OHRQoL of children and family. The hypothesis was that the presence of severe dental trauma produces a significant negative impact on oral health-related quality of life of the child and family.

METHODS

Subjects and study design

This cross-sectional study was approved by the Human Research Ethics Committee of the University of Pelotas. An epidemiological survey was conducted with children at 2 to 5 years-old and their mothers, during the Day of the Children National Vaccination Campaign. According to the Ministry of Health, acceptance of the program in Pelotas was 90% among children up to 59 months. Of these children, only a small percentage (4%) was vaccinated in other places than public health centers. A two-stage sampling procedure was adopted in order to ensure representativeness of the sample. Using a probability selection method, with probability proportional to the size of the Basic Health Units (BHU), nine BHU were randomly selected out of 25 existing in town that have dental office, from the relation obtained from the Municipal Health, considering the expected attendance of children at each site. In each of the seven administrative areas in which the city is divided there was at least one sampling point. Only BHU located in the urban area of Pelotas and equipped with dental offices were included.

For the present study, a minimum sample size of 293 children was estimated, in line with an estimated prevalence of impact in OHRQoL of 7.4% [2], a margin of error of 3 percentual points, and a confidence level of 95%. To cover non-response, the sample was increased by 20% to 391 mother–child dyads.

Data collection

Data were collected through clinical examinations and interviews by 12 examiners, graduate dental students, and 35 assistants. The data collection consisted of interview and oral health exam of child. Previously to conducting the survey, a pilot study with 13 children was conducted to test the operability of the proposed methodology.

After the child had been vaccinated, mothers were invited to participate in the survey. All mothers signed an informed consent form and answered a questionnaire that included demographic and socioeconomic information. The outcome was assessed by Brazilian version of Early Childhood Oral Health Impact Scale (ECOHIS) [13,14], applied to the mothers to evaluate their perception about OHRQoL. The instrument consists of 13 questions, including a child impact section (symptoms, function, psychological, self-image/social interaction domains) and a family impact section (parent distress and family function domains). Answers were recorded using a Likert scale, with response options coded from 0 to 5 (0 = never,1 = hardly ever, 2 = occasionally, 3 = often, 4 = very often, and 5 = do not know). To those who responded “do not know” in up to 2 items in the child section and 1 in the family, a score for the missing values was obtained from the average of the issues section [15]. The total score is obtained through the sum of scores and can range 0-52. Impact was considered present when ECOHIS was = 1. Also, the prevalence, intensity and extent of impacts were evaluated. The prevalence of impact refers to the proportion of subjects that reported ‘hardly ever’, ‘occasionally’, ‘often’ and ‘very often’ for at least one daily life performance. The extent was considered the number of performances (items of questionnaire) affected. The intensity of the impacts referred to the highest score reported by the mother for the 13 items and was used to classify subjects into groups.

The oral examination of the child was performed in the dental office under artificial light, using wooden spatula, gauze, mirror and CPI probe and following the precepts of biosecurity [16]. Children who did not allow oral examination were excluded from the study. The mothers were informed about the oral health status of children and those who sought treatment were included in the University Pediatric Clinic as needed.

The maxillary anterior teeth were evaluated for the presence and degree of traumatism [17]. The type of trauma was categorized as mild trauma, when limited to the enamel and not requiring restorative treatment, and as severe trauma, when involving at least the dentin [18]. The condition of the crown was evaluated by the WHO dmft (number of decayed primary teeth, missing or restored), each component being tracked individually [16]. The presence of anterior open bite was also evaluated [19].

The child’s age (24-35, 36-47 or = 48 months), family income (tertiles) and maternal education (> 8 or = 8 years) and dental caries and maloclusion were collected and used as control confounders.

Training and calibration

Interviewers were previously trained, and examiners received theoretical training and underwent a process of calibration with 20 children, previously selected to present different types of dental trauma. The first stage consisted of a 4-hours theoretical training, about the interview and clinical examination. In the second stage, examiners proceeded to the oral clinical examination of 15 children at the Clinic of Pediatric Dentistry, Faculty of Dentistry, Federal University of Pelotas. The inter-examiner agreement ranged from 0.70 to 1 for occlusion, 0.70 to 0.93 for dental trauma and 0.85 to 0.96 for caries. Intra-examiner agreement, calculated from the re-examination of the children after one-week interval, was 1 to occlusion and ranged from 0.70 to 1 for trauma and caries.

Statistical analysis

Data were analyzed using the software Stata 12.0 (Stata Corporation, College Station, USA). Initially, descriptive analysis of the data was taken. Chi-squared test was used to compare the prevalence of impact in children with mild/absent dental trauma and children with severe dental trauma. The impact of the independent variables on overall and domain-specific scores ECOHIS was evaluated using logistic regression analysis (Odds Ratio; 95% Confidence Interval). Multiple linear regression models using ‘forward stepwise’ entry procedures were used to assess the independent effects of variables on ECOHIS scores. All variables derived from the clinical examination and interview were used in the regression analyses as confounders. For multiple regression analysis, all the variables in the bivariate analysis with p = 0.20 were included in the construction of model. A significance level of 5% was adopted.

RESULTS

A total of 599 preschool children were included. Table 1 shows characteristics of the sample. It was observed that 50.7% were girls, 45.5% of families were in first tertile of income and 60.9% were caries free. A total of 176 children (29.4%) had dental trauma: 131 (21.9%) presented with enamel fracture only, 11 (1.8%) with enamel and dentine fracture, 11 (1.8%) with fracture with pulp involvement, 15 (2.5%) presented signs of discoloration and/or fistula and 8 (1.3%) suffered avulsion.

DISCUSSION

The present study showed that children with severe traumatic dental injuries (involving at least the dentin [18] had a higher prevalence of negative impact on OHRQoL than children with no or with mild injuries. However, differences were not detected in mean scores (extent) between groups, nor in the intensity of impacts. The rationale for the exclusion of fractures limited to enamel is that these injuries do not require treatment, have a low chance of sequelae and may go unnoticed by parents. This can also explain the findings of the study.

Children were recruited during a vaccination campaign in the city of Pelotas. Since the vaccination program has a wide coverage and the centers selected encompass nearly 60% of the children attending the vaccination program, the sample can be considered representative of the population of preschool children in Pelotas [20]. Another strength of the study was the use of a validated and specific instrument to evaluate the negative impact of oral diseases on the quality of life of preschool children. Besides, dental caries and anterior open bite were included in the adjusted analysis because can act as confounders in the association between dental injuries and OHRQoL. However, this study included only the health units located in the urban part of the city and, therefore, the findings are representative of the children living in the urban region. As children living in the countryside may have different oral health conditions, further studies evaluating the rural population should be conducted.

Results are in accordance to previous study, undertaken with preschool children attending public nurseries, which showed that enamel fractures do not impact OHRQoL [9]. Previous studies have detected divergent results [8,21], probably due to methodological differences. Dental trauma was previously evaluated using Andreasen criteria, that consider presence of TDI when at last one type of trauma is present [2], [3] and Glendor criteria, that classifies trauma in complicated and uncomplicated injuries [21]. In a study performed by Viegas et al. [3], the presence of TDI had no impact on quality of life of the children and their families, with exception of the cases of avulsion, which had impacted the quality of life. Abanto et al. [21] observed that children with complicated injuries were more likely to experience a negative impact. Kramer et al. [2] has adopted the same cut-off point for the ECOHIS instrument used in the present study and showed that the prevalence of any impact on OHRQoL was 70% higher in children with TDI.

Considering the different domains of the instrument, a presence the severe TDI as associated with higher frequency of impact in family function and symptoms domains. Borges et al. [22] in its meta-analysis, found that TDI caused a negative impact on OHRQoL based on overall ECOHIS, as well as scores in the child impact section, but not in the family impact section. Regarding to the family function, severe injuries can mobilize the family, which ends up expending greater attention to child, due to the severity of the lesion, reflecting in all familiar function [23], what justifies our findings. The presence of impact on symptoms domains indicates that injuries were associated with pain, producing a great discomfort and impact on child daily activities [4]. This reinforces the importance of excluding children with fracture restricted to enamel in the present analysis of the association between TDI and OHRQoL.

The perception of impact may be related to the living conditions of the individuals. However, in preschool children, the influence of the socioeconomic status of the family has showed divergent results. Abanto et al. [4] found that a lower family income had a negative impact on the quality of life of parents as well as Wong et al. [24], which also showed a tendency for caregivers with lower income to report greater scores. In the present study no significant relationship between family income and the impact on quality of life, as well as in studies by Kramer et al. [2] and Vollú et al. [25]. However, it should be noted that previous study with this sample, adopting the ECOHIS total score, and not the absence/presence of impact, had detected such association [20], showing that socioeconomic condition influences in the intensity of perceived impacts.

Oral diseases may represent stressful situations to child and family. The occurrence of dental trauma or caries and its consequences, such as pain, may influence the overall development of the child [26]. Knowledge about the impact of oral diseases on quality of life of children is essential for the formulation of strategies to prevent and treat these problems. The perception and attitude of parents about oral health of their children proves decisive for the occurrence of negative impact on quality of life and, in some cases, demonstrates the care expended upon to child. The perception of parents is of outmost importance, since it could influence the decisions of oral health and consumption patterns of health care [20]. For older children, ages 5 and 6, the Scale of Oral Health Outcomes for 5-year-old children (SOHO-5) which associates the child’s self-report and the parents’ report, can also be a satisfactory alternative to measure the quality of life related to oral health [27].

The interest in measuring the impact of oral health on quality of life of children has increased significantly due to the possibility of providing information about this population in terms of treatment needs and associated limitations, implying the need for oral health promotion. Oral diseases affect individual not only physically, but also psychologically, regardless of age. The severity of oral diseases may affect how the child grows, enjoy life, taste food and socialize. In this context, how the parents perceive and act facing oral problem in child and how health services are organized to meet the needs identified, whether preventive or treatment, are an essential dyad to maintain the quality of life of the child and family.

The measurement of clinical indicators added to an evaluation of the influence of the oral health condition on daily life is important to help develop strategies to minimize oral health problems in children, since it provides a consistent information about the impact of oral diseases on quality of life of children and their family. The identification of risk factors for impaired quality of life encourage the search for preventive dental care and helps to set adequate approaches considering the health-disease process within the context of each patient [5].

CONCLUSION

In conclusion, the results showed that the occurrence of severe dental trauma impacts on oral health-related quality of life of preschool children and their families, mainly on symptoms and family function domains. Results strength the importance of health promotion strategies aimed at preventing trauma in preschool children and of providing treatment for severe injuries.
