Demographic and dental profile of patients met in the Dental Center for Patients with Special Needs of the Brazilian Association of Dentistry-Rio de Janeiro

Objective: to evaluate the demographic and dental profile of patients with special needs met in a Reference Center in the state of Rio de Janeiro, showing their main needs and the possibility of outpatient care. Material and Methods: the sample consisted of 410 patients, from whom demographic and clinical data were obtained. All the studied variables were entered in a database for descriptive statistical analysis. Results: two hundred and twenty-seven (55%) patients were male, 70% were white, and their average age was 34 years old. Inconclusive diagnosis, followed by autism spectrum disorder and intellectual disabilities, were the most found diagnoses. Most patients (78%) was from the metropolitan region. Regarding complaints and dental procedures, the main complaint was prevention (28%), and 2,902 procedures were performed. Concerning oral hygiene habits, 264 (64%) patients did not floss and 215 (52%) underwent toothbrushing three times a day. Only 57 (14%) cases required the use of sedative methods to carry out the dental treatment. Conclusion: there is a great demand for preventive and restorative treatments for patients with special needs, highlighting the need for daily strengthening practices of oral health promotion. In addition, we can see that most treatments performed were in the outpatient level, showing that the use of appropriate approach is essential for dental management, thus demystifying the care of these patients.


Introduction
A ccording to Gullikson (1973), a special patient is any person, adult or child, who physically, intellectually, socially, or emotionally diverges from what is considered normal regarding growth and development patterns.Thus, these patients cannot receive regular and standardized education, requiring special education and supplementary instruction in appropriate services for the rest of their life. 1he World Health Organization (WHO) estimates that the prevalence of disabilities in the world is of one every ten people, and says that, of this total, more than two thirds does not receive any type of oral health care. 2,3Most of these individuals lives in underdeveloped or developing countries, with only 2% receiving adequate care focused on their needs.In Brazil, according to sources of IBGE (2002), 24.5 million people have special needs, i.e., 14.5% of the Brazilian population have some type of disability. 4 According to the National Policy of People with Disabilities (Política Nacional da Pessoa com Deficiência) -tool of the Brazilian Ministry of Health that guides the several sectors of health care to meet people with disabilities -, the comprehensive health care of these patients include oral and dental care, accompanied by hospital procedures and others, in specific cases. 5ental problems, especially periodontal disease and tooth decay, are frequent in these patients.][8][9] Unfortunately, nowadays, this large group of patients are still unattended and discriminated, being excluded from society and showing poor oral health conditions.For some dentists, meeting patients with special needs may present some difficulties, generating an idea that this service is infeasible in the outpatient level.Therefore, it is greatly important to know the profile and promote the social inclusion of these patients, providing an egalitarian dental treatment. 5hus, this study aimed to evaluate the demographic and dental profile of patients with special needs met in a Reference Center in the state of Rio de Janeiro, showing their main needs and the possibility of outpatient care.

Discussion
The dental care to patients with special needs requires specific care, and knowing the clinical and demographic profile of these individuals is essential.Information such as age group, age to seek care, origin, diagnosis, main complaint, and oral hygiene habits are essential so that the professionals involved can prepare an appropriate treatment plan, establishing protocols of humanized and personalized care that show and reinforce the importance of dentistry in the multidisciplinary treatment of patients with special needs.
This study has shown that the sociodemographic profile presented no difference regarding sex, with a slightly increased frequency of males compared to females (55% and 45%, respectively).These data are similar to Silva et al., 10 who identified 52% of males and 48% of females.According to the data of the 2010 Census, conducted by the Brazilian Institute of Geography and Statistics (IBGE), until 2010, 26% of the female population (25 million) had some disability, against 21% of the male population (19 million). 11Regarding skin color, our data showed prevalence of white skin color, with 70% of all individuals.These results may be associated to a restriction of access to specialized dental care by mixed-race and black populations, which still greatly represent the low-income population in the state of Rio de Janeiro and in Brazil.According to IBGE (2010) data, racial groups differ concerning epidemiological, demographic, socioeconomic characteristics and access to services. 11Rohr and Barcellos report that the socioeconomic condition is a significant factor for the use of oral health services, in which individuals from the most favored economic classes seek more for dental services. 12egarding age, we identified a range from 2 to 90 years old, in which younger patients often presented congenital and behavioral anomalies.According to Silva et al. 10 and Acerbi et al., 13 these data may represent the lower life expectancy of these individuals compared to the population, reinforcing the importance of providing a specialized care in the early years of life.][5] It is important to observe the origin of 22% of the patients, who were living outside the capital, but sought care at the Center for lack of specialized services, which is against the basic principles of universality and equity of the Brazilian Unified Health System (SUS).][16][17] This information reinforce the importance of establishing partnerships with universities outside the metropolitan region of Rio de Janeiro to promote greater inclusion of these patients, in addition to encourage education and motivation programs of oral hygiene to be held by undergraduate students in dentistry, which makes their academic training more complete and safe within an inclusive context.
Concerning the diagnoses identified among these patients, this medical information was obtained from 410 individuals, and the highest percentage was of inconclusive diagnoses, which are mostly associated with bad congenital formations.According to Camelier et al., 18 despite the molecular origins of congenital malformations are increasingly known, an average of 50 to 60% of cases occur because of unknown causes.Then, the diagnosis of autistic spectrum disorder was obtained, with 11%, followed by Down syndrome, with 10%.According to Rutter 19 , the prevalence of autism in the world's population varies from 4 to 13/10,000, occupying the third place among child development disorders, being ahead of Down syndrome.
Regarding the need to seek care, most (28%) guardians were seeking preventive measures, reporting great concern with oral problems, since they might cause further damage in the physical and mental integrity of the patient.However, an advanced age was found for patients seeking their first care (average of 34 years old).These data can be justified by an exhaustive routine of medical consultations, which may lead to actions of neglect and forgetfulness concerning oral health care.In addition to this, there is still a significant lack of knowledge of the importance of dental monitoring and education for providing a best quality of life to special patients since their first years of life. 20Casamassimo et al. 21conducted a study in which they reinforce the difficulty of dentists in meeting patients with limitations.Their research showed that only one every four professionals could work with this type of patient during their undergraduate studies, not presenting difficulty in the care of these children.The reduced number of services and professionals specialized for this care decreases the supply of service.
Concerning oral hygiene habits, most guardians and/or caregivers reported performing toothbrushing three times a day, but not always effectively, given the difficulty in handling.We observed that flossing is rarely performed, since it is not a common practice in everyday life.This situation is aggravated by the lack of training programs for caregivers, financial cost, unfamiliarity of parents regarding the pos-sibilities of training, and prioritization of the treatment of other systemic problems.According to Flório et al., 22 when PSN are not able to perform oral hygiene care by themselves, the caregiver becomes responsible for it.However, they often feel little motivated or have no knowledge on how to perform a satisfactory oral hygiene, besides reporting difficulties in performing it.The difficulties, according to the caregivers, are associated with handling these individuals, since most present motor limitations, aggressive behavior, and lack of interest and cooperation. 22actors such as poor oral hygiene, unprivileged socioeconomic condition, mouth breathing, occlusion anomalies, cariogenic diet, and use of medicines are common in patients with special needs. 23,24This study found that, among the procedures performed, restorative and preventive treatments were prevalent.In general, individuals with special needs have a higher prevalence of tooth decay. 25This meets with the large number of restorative procedures identified in this study.However, there is a significant number of patients in monitoring and prevention programs, showing that it is possible to change the paradigm of PSN with missing and decayed teeth.
We also found a small percentage of procedures performed in the areas of Endodontics, Prosthodontics, and Orthodontics, showing the feasibility to perform a dentistry that requires more collaboration and has an aesthetic purpose in patients with special needs.Dougall & Fiske 26 state that, since the life expectancy of patients with special needs is increasing, the importance of keeping teeth in a stable, healthy, and functional occlusion has become a major focus for improving their quality of life.Thus, there is a tendency to promote more restorative and endodontic treatments rather than tooth extractions.However, it should be noted that such procedures must have a precise indication and a proper collaboration of oral hygiene, by instructions and routine consultations, to ensure the ultimate success of these therapies.
The patient must be introduced to the dental environment in the first year of life, so that the mother receive guidance on the oral hygiene of the child and required preventive measures may be carried out, using psychological conditioning, mainly by talk-show-do techniques, in which the stimuli are gradually presented. 27However, some patients do not respond to this approach because they present different degrees of mental impairment that affect their ability to cooperate.In these cases, the alternatives to carry out the dental treatment are preoperative sedation with medication, sedation with nitrous oxide/oxygen, and, in the last case, general anesthesia. 28,29r study showed that, of the 410 patients, only 57 (14%) required the use of sedative methods, showing that outpatient care to special patients is possible if different methods of adaptation to the environment and to dental care are employed, always with persistence and boldness.Schardosim et al. 30 mention that the essential tools to carry out outpatient care to PSN are welcoming, desensitization of patients -regardless of their ability to collaborate -, and bonding with the family, making these the major principles that allow the dentist to approach and gain the confidence of the patient.
Of this small number, 21 had their treatment carried out in operating room under general anesthesia.It is worth noting that this is a precise indication, since the degree of cooperation of the patient and the complexity of the procedure must be carefully examined. 31s alternative sedatives methods, conscious sedation was employed with benzodiazepines administered orally and/or inhalation sedation with nitrous oxide and oxygen, which, used safely and effectively, essentially aim to reduce the anxiety and fear of the patient, allowing outpatient care. 29These data show that these procedures are a solution, favoring the reduction of dental care in the hospital environment.However, it is important to mention that the in-depth knowledge of these techniques, their risks, and benefits is essential, as well as the monitoring of the vital signs of the patient. 32,33

Conclusion
The average profile of patients with special needs is characterized by white male patients, with an average age of 34 years old, from the metropolitan region, with inconclusive diagnoses, autism spectrum disorder, and Down syndrome.In addition to this, a great concern for prevention of oral diseases was observed, despite the late search for dental care and lack of flossing and toothbrushing.Regarding dental treatments, restorative and preventive procedures prevail, with rare use of sedative methods.Thus, by using an appropriate approach, it is possible to perform outpatient dental care to these individuals, which is fundamental to reestablish and maintain their quality of life.
