Objective: Identify self-rated oral health dimensions of institutionalized elderly in Brazil using the Geriatric Oral Health Assessment Index (GOHAI), and seek associations with objective, subjective and behavioral conditions.

Methodology: Cross-sectional study based on a census of institutionalized elderly. A total of 1192 individuals, living in 36 long-stay institutions for the elderly (LSIE) were evaluated. Of these, 587 (49.2%) responded to the GOHAI. A questionnaire containing subjective and oral health behavior questions was applied and an epidemiological survey (WHO criteria) conducted.

Results: With regard to the psychosocial dimension, multiple regression analysis demonstrated that the variables absence and need for upper prosthesis remained significant. Variables for the physical dimension were presence of dental problems and CPI of 6 mm or more, while in the pain or discomfort dimension, it was opinion of teeth, gums or prosthesis.

Conclusions: A better understanding of GOHAI dimensions may increase knowledge of oral health conditions among institutionalized elderly in Brazil, thereby contributing to action planning, organization and monitoring of health services besides improved health and quality of life.


Oral Health; Geriatrics; Nursing Homes; Institutionalization


Brazil is in rapidly aging process and this fact can be understood by analyzing the Brazilian population pyramid. In this, the base - birth rate index - is becoming even narrow, although, the apex - population aging index - is becoming more extensive. Following this reasoning, statistics from the World Health Organization (WHO) show that in the period 1950-2025, the Brazilian population will increase by 15 times. This fact will lead Brazil to occupy the sixth place as the number of elderly, reaching about 32 million people over 60 years of age [1].

In this context, it’s important to target the general health of this population, and we should also emphasize oral health, because when neglected, will result in a decrease in self-esteem, nutrition, in other words, the quality of life in general [2]. For this importance to be given, it is necessary to pay greater attention to public policies related to this group. However, it’s essential to understand how the elderly perceive and evaluate their oral conditions, because this perception conditions the patient to seek professional aid.

Nevertheless, it’s unusual for people to identify oral health conditions as their only health problems when those issues are so advanced that they affect feeding ability, speaking, chewing, physical appearance, and social life, frequently producing pain and favoring depression [1-4]. Oral health expectations among the elderly could also be influenced by age, education level, socioeconomic situation, and social support [3].

Self-rated oral health is a multidimensional measure reflecting the subjective experience of individuals regarding their functional, social and psychological well-being [5]. It can be used as a general indicator of treatment needs or to estimate the effect of oral conditions on daily life [6]. Several factors may influence this perception, including socioeconomic characteristics [7-10], objective oral health conditions [7,11-13], cultural values, social welfare, previous experiences, psychological experiences, age, gender and belief that some pain and disabilities are natural of aging [1,4,14,15].

Identify the determinants of self-perceived oral health has proven crucial to understand people’s behavior and how they evaluate their needs [16,17]. In individual oral health care, knowing the individual’s outlook on their health is important to improve individuals’ adherence to healthy behavior conditions [18,19]. In the case of the elderly, this aspect becomes more relevant because the main reason for not seeking dental service is the fact that they don’t perceive a need for dental care [4,13,17].

There are indicators used to assess the subjective perspective which were originally called ‘socio-dental’ or ‘oral health status’ indicators. These terms have been replaced by the ‘Oral Health-Related Quality of Life’ (OHQoL), which emphasizes the impact of oral diseases and disorders on an individual’s functioning and psychosocial well-being [20].

Measures of oral health-related quality of life (OHQoL) are essential for epidemiological and clinical studies to provide accurate data for health promotion, disease prevention programs and allocation of health resources [20-24].

One of the most used instrument to estimate the OHQoL in elderly, is the Geriatric Oral Health Assessment Index (GOHAI) [17,25], which was developed by Atchinson and Dolan in 1990 [1,4,14,20,21,24,26,27] to assess three dimensions of oral health as follows: physical functioning, social functioning and pain and discomfort [9,20,25,28].

Thus, the aim of the present study was to identify oral health-related psychosocial, physical and pain aspects in institutionalized elderly in Brazil, using the GOHAI. We also sought to determine associations between these aspects and objective and subjective health conditions, factors related to oral health behavior, individual characteristics and environmental factors.


This is a cross-sectional study of institutionalized elderly in Brazil. It was carried out in 2007 and 2008 and based on the STROBE protocol [29]. A refinement in statistical analysis, which will bring important contributions in the process of interpretation that older people make about their oral health status, was made from the study of Piuvezam et al. [17]. This can help professionals as well as public policies improvement regarding the actions directed to this population in Brazil. The investigation was approved by the Research Ethics Committee of the Federal University of Rio Grande do Norte (CEP-UFRN).

The study involved a census of institutionalized aged subjects from a random sample of 11 mid-sized and large municipalities in the five geographic regions of Brazil (North, Northeast, South, Southeast and Midwest). The following inclusion criteria were adopted:

1. Municipalities with 100 thousand inhabitants or more, according to the population projection list of the Brazilian Institute of Geography and Statistics for 2005

2. Municipalities with an elderly population greater than or equal to the median found in each geographic region.

The long-stay institutions for the elderly (LSIE) studied were private and philanthropic, and duly registered in their respective localities. In accordance with legal guidelines established in the National Policy for the Elderly [30], the sample was composed of individuals over the age of 60 years.

Aged participants presenting cognitive conditions, according to the clinical diagnosis of the LSIE physician, responded to the GOHAI [25]. The survey contains 12 questions scored between 1 and 3, that is, a range of 12 to 36 points for the overall index, characterizing the worst and best assessment, respectively. Responses are arranged on a scale of three response categories (always, at times or never) except for question 7 where these values were inverted to maintain the highest values for positive conditions in all questions. Thus, the higher the overall and individual dimension score the more favorable oral health-related quality of life [31]. The Brazilian version, validated by Silva [31], was used applied, using Cronbach’s alpha of 0.65 for dentulous and 0.76 for edentulous individuals.

The psychosocial dimension of GOHAI contains 5 questions involving concern about oral health, self-image, awareness of health, and oral-related social contact limitations, with a maximum score of 15 points. The physical dimension has 4 questions and encompasses aspects of eating, speaking and swallowing, with a maximum score of 12. The pain and discomfort dimension is associated to oral-dental status and contains 3 questions with a maximum score of 9 points. Questions related to each dimension are shown in Figure 1. In this study, GOHAI dimensions were considered dependent variables. Each dimension was categorized from the median values of positive or negative self-rated oral health conditions.


Figure 1: List of GOHAI questions in the psychosocial, physical and pain or discomfort dimensions

Individuals with cognitive conditions, as per the clinical diagnosis of the LSIE physician responded to a 4-question survey. Three of these were subjective and related to oral health conditions and 1 corresponded to oral health behavior, determined from data recorded at the last dental visit [16,32].

An epidemiological survey of oral health status was conducted using the DMFT, community periodontal index (CPI), periodontal loss of attachment (PLA) and prosthetic use and needs, according to World Health Organization (WHO) criteria [33]. Data were collected by 5 calibrated dentists, yielding inter and intra-examiner Kappa values between 0.71 and 0.89. Information was also gathered on sex, age and dependence of the elderly (dependent or independent), in accordance with to the clinical diagnosis made by the LSIE physician.

A questionnaire on geographic location, type of institution (philanthropic or private), Family Health Strategy (FHS) coverage and oral health activities (preventive or curative) was applied at each LSIE.

The inter-variable relationship was based on a theoretical model proposed by Gift, Atchinson and Durry [34], adapted for this study, presenting the interrelationship between the following 6 groups of variables: external environment, individual characteristics, oral health related behavior, objective and subjective oral health conditions and self-assessment of oral health (Figure 2).


Figure 2: Adaptation of the model proposed by Gift et al. [19].

Descriptive analysis was performed using absolute and relative frequencies of qualitative variables, as well as means, standard deviations, medians and quartiles for quantitative variables. Bivariate analysis used chi-square and Fisher’s exact tests to determine the association between variables. The magnitude of the effect of independent variables on the result was expressed by prevalence ratio (PR). A confidence level of 95% was adopted for all statistical tests. In order to analyze the independent effect of intervening variables on the outcome, multiple logistic analysis was performed using the forced entry model building procedure. All independent variables with p<0.20 in the association test were included. Model fit was determined by the Hosmer – Lemeshow test and analyses were conducted with Stata 10.0 software (Stata Corp., College Station, Texas).


Total population for the 36 LSIE investigated was 1412 individuals. Of these, 1192 (84.4%) took part in the present study and 587 (49.2%) exhibited suitable cognitive capacity to respond to the GOHAI. Of these, 51.4% were men. Age ranged between 60 and 106 years and was categorized from the median, with mean age of 74.98 + 9.5. Most subjects live in philanthropic institutions and a minority are residents in facilities covered by the Family Health Strategy (FHS). Fewer than half receive any type of oral health care (Table 1).

Table 1: Characteristics of institutionalized elderly in Brazil, according to individual traits, objective and subjective conditions, oral health behavior, and external environment

Questionnaire data showed that only 20% of the elderly had consulted a professional within the previous year. Questions about the presence of dental and gum problems were responded to by 40.8% of subjects since the response condition was having at least one tooth. Answers related to opinion on teeth, gums or prostheses had 96.9% respondents and most reported a good or excellent opinion (Table 1).

Data regarding objective conditions of oral health indicate mean DMFT of 28.8 (± 5.5) (Table 1). Approximately half the individuals exhibited total tooth loss. When analyzed from the perspective of functional edentulism, the situation is even more serious, with 84.2% of the elderly presenting with 20 or more missing teeth.

Prosthetic rehabilitation was inadequate, as evidenced by the fact that around 54.2% and 74.1% of individuals used no type of upper and lower prosthesis, respectively. Among elderly participants using some type of upper or lower prosthesis, most wear total prostheses (40.9%) in the upper arch and 21.6% in the lower arch (Table 1).

With respect to the need for rehabilitation, results show that 45.8% do not require upper arch prostheses. Of those who do, 38.5% needed total prostheses and 14.1% some form of fixed or removable prosthesis. In the lower arch, 25.9% do not require prostheses and among those who do 257 individuals need total prostheses and 27.9% a fixed or removable prosthesis.

Periodontal conditions were analyzed using CPI and PLA indices. These were identified in sextants exhibiting the worst conditions for each individual. Thus, the most significant values for periodontal infirmities demonstrated that 18.6% exhibited calculus according to CPI criteria. And in relation to PLA results it was found that 10.1% displayed attachment loss of 4 to 5 mm. For bivariate and multivariate analysis, these variables were characterized for CPI in the absence of pockets for the healthy, bleeding and calculus categories and the presence of pockets for the others, as well as losses between 0 and 5 mm and 6 mm or more for the PLA variable.

In relation to the Geriatric Oral Health Assessment Index (GOHAI), Figure 3 shows that elderly subjects evaluated their oral health conditions as positive for most questions. Bivariate and multivariate analyses considered psychosocial, physical and pain dimensions as dependent variables. Results are shown in Tables 2-4. Prior to multivariate analysis, collinearity was sought among all variables considered for the model, using the tolerance test and VIF (Variance Inflation Factor) values. No multicollinearity was detected.

In the psychosocial dimension, the following variables remained significant in the model after multivariate analysis: opinion about teeth, gums and/or prosthesis, absence of upper prosthesis and the need for upper prosthesis (Table 2).

For the physical dimension of GOHAI, where elderly participants express a general opinion about the status of their teeth, gums or prostheses, individuals that rated their condition as fair or poor also exhibited negative self-perception.

Finally, in relation to pain, only the variable of opinion about teeth, gums or prostheses remained significant. Therefore, elderly subjects who described their condition as bad or terrible were 5 times more likely to exhibit negative self-evaluation in the aforementioned dimension.


Psychosocial dimension

This aspect involves psychological issues, emotional and socioeconomic, as well as cultural and spiritual issues [35]. Thus, this dimension shows how the individual behaves in society, its concern or care of their oral health, dissatisfaction with appearance, self-awareness on oral health and avoidance of social contacts due to dental problems [18]. It is worth pointing out that the body changes determined by the aging process have psychosocial implications that results and generates events that cause different behaviors such as inactivity, loneliness, isolation and prejudice [36].

After data analysis, it was identified that when institutionalized elderly participants exhibited an absence of or need for rehabilitation in the upper arch, their self-assessment in the psychosocial dimension of the GOHAI was negative. This is because the absence of upper teeth generates social, psychological and functional limitations, primarily in relation to esthetic questions [19]. These individuals experience eating difficulties and likely feel restricted in the presence of others. Another element concerns communication difficulties. Despite being institutionalized, subjects manifest their individuality regardless of living in a collective environment [37].

Furthermore, literature studies have shown that the absence of teeth may have a negative influence on self-rated oral health [38-40], and that the elderly tend to improve in this area after rehabilitation [41-44].

With regard to opinion about teeth, gums and/or prostheses, psychosocial dimension results were not surprising. This is because individuals displayed negative self-evaluation when expressing a bad opinion about their poor oral health conditions, confirming GOHAI results.

Physical dimension

Consists in physical function, physical performance, physical pain and general health also involving issues of eating, speaking and swallowing [18,45,46].

The aging process promotes changes in orofacial functions, these are related to adjustments in oral functions caused by tooth loss, use of poorly fitting dentures, loss of muscle tone and psychomotor retardation [47,48]. Still occur changes in taste perception, the elderly may lead to loss of desire to eat, chew and pleasure in the act of eating. Due to adversity elderly seeks less consistent food and at the same time it can cause atrophy of the masticatory muscles, with repercussions in facial aesthetics and self-esteem [48,49].

Regarding elderly who have natural teeth, those related problems concerns to periodontal aspects, which make the teeth less steady and chewing extremely difficult [48].

When analyzing the data, it was observed that subjects exhibiting dental problems, diagnosed with periodontal attachment loss of 6mm or more, demonstrated negative self-perception on physical dimension questions. PAL results indicate severe periodontal attachment loss and dental mobility. Thus, self-reported dental issues may translate into dental mobility since the aged do not associate it with periodontal problems. These findings are confirmed in the literature, where studies indicate periodontal problems may be predictors of self-assessed oral health [50,51].

Pain/Discomfort Dimension

Pain is one of the most common reasons for older people to seek medical attention [52] and this can be defined by the International Association for the Study of Pain (IASP) as “an unpleasant sensory and emotional experience associated with present or potential tissue damage. The pain is always subjective. Each individual learns to use this term through their previous experiences related to damages.” In other words, pain is considered a multifactorial phenomenon, which sensation and perception will vary individually, according to the influence of biological, psychological and social factors [53].

Pain is also related to the discomfort while chewing, tooth and gum sensitivity and finally the need for medications to relieve pain or discomfort for the oral cavity [18,46].

Through the literature review it can be seen that the absence of teeth can have different meanings for those who lose. Among them we can mention the mutilations to the body, in other words, the view that the elderly have on how his tooth was lost, representing a real aging and when there are indications of prosthesis. These meanings can interfere negatively, because it promotes a feeling of shame and creates the expectation that the prosthesis can replace the original tooth, performing the same function with equivalent quality. Fear of long treatments, and the greater cost for conservative treatment, encourage the transition to the edentulism [48].

In the study of Unfer et al . [54], it was reported by the elders that the reason for loss of teeth is associated with the lack or difficulty of access to dental services, lack of knowledge about the causes and control of dental disease and the consequence of the dental care model, this, may be explained by the surgical-restorative attention model used in the past [54]. With data analysis, only the opinion of teeth, gums or dentures had significant value and thus the elderly who described their condition as poor or very poor, presented higher conditions of a negative self-perception.


Results show that GOHAI analysis, mediated by the psychosocial, physical and pain dimensions, showed correlations with variables expressing these dimensions, primarily with regard to objective oral health conditions. These findings underscore that both subjective and objective aspects have an impact on self-rated oral health. Clinicians are therefore recommended to carefully assess elderly patients’ complaints, considering their frailties and comorbidities.

The use of self-perception of oral health assessments as GOHAI dimensions, can reveal information that is not obtained by objective indicators of oral diseases, to mention the psychological and social factors that may contribute to public health planning that promotes health and compose preventive and rehabilitation actions as well as activities to guide and encourage the elderly to the importance of selfcare [55,56].

Finally, a better understanding of relationships established between self-rated oral health based on GOHAI dimensions may increase knowledge of oral health conditions among institutionalized elderly in Brazil, thereby contributing to action planning, organization and monitoring of health services [57] besides improved health and quality of life [58].
