Evaluation of patients with Alzheimer's disease before and after dental treatment

Avaliação de pacientes com doença de Alzheimer antes e depois do tratamento dentário

Abstracts

Oral infections may play a role in Alzheimer's disease (AD).

Objective

To describe the orofacial pain, dental characteristics and associated factors in patients with Alzheimer's Disease that underwent dental treatment.

Method

29 patients with mild AD diagnosed by a neurologist were included. They fulfilled the Mini Mental State Exam and Pfeffer's questionnaire. A dentist performed a complete evaluation: clinical questionnaire; research diagnostic criteria for temporomandibular disorders; McGill pain questionnaire; oral health impact profile; decayed, missing and filled teeth index; and complete periodontal investigation. The protocol was applied before and after the dental treatment. Periodontal treatments (scaling), extractions and topic nystatin were the most frequent.

Results

There was a reduction in pain frequency (p=0.014), mandibular functional limitations (p=0.011) and periodontal indexes (p<0.05), and an improvement in quality of life (p=0.009) and functional impairment due to cognitive compromise (p<0.001) after the dental treatment. Orofacial complaints and intensity of pain also diminished.

Conclusion

The dental treatment contributed to reduce co-morbidities associated with AD and should be routinely included in the assessment of these patients.

Infecções orais podem ter um papel na doença de Alzheimer (DA).

Objetivo

Descrever as características orofaciais, dor, odontológicas e fatores associados em doentes com DA submetidos a tratamento dentário.

Método

29 doentes diagnosticados com DA por neurologista foram avaliados através do Mini Exame do Estado Mental e questionário Pfeffer. O exame odontológico foi realizado antes e depois do tratamento dentário e incluiu: questionário clínico; critérios diagnósticos de pesquisa para disfunção temporomandibular; questionário de dor McGill; protocolo de impacto de saúde oral; dentes cariados, perdidos e obturados; e avaliação periodontal. Os procedimentos mais frequentes foram raspagem periodontal, exodontias e prescrição de nistatina tópica.

Resultados

Houve uma redução na frequência de dor (p=0,014), limitações mandibulares (p=0,011), índices periodontais (p<0.05), e melhora na qualidade de vida (p=0,009) e no comprometimento funcional e cognitivo (p<0,001) após o tratamento dentário. Queixas orofaciais e intensidade de dor também diminuíram.

Conclusão

O tratamento dentário contribuiu para reduzir comorbidades associadas à DA e deveria ser incluído na rotina de avaliação desses pacientes.

In the last century the world population got older, and since then there has been a growing interest in maintaining health and an active and functional life in the third age. The frequency of elderly people with chronic diseases is high (20%-35%), and many of them are fragile (2%-10%)1Freedman GM. Chronic pain: clinical management of common causes of geriatric pain. Geriatrics. 2002;57(5):36-41.. Neurodegenerative diseases cause severe morbidity, and among them Alzheimer's Disease (AD) are progressive and still do not have an effective treatment; therefore, there is an interest in preventing it, improving the quality of life of these patients and reducing the speed of progression2David R, Piano J, Robert P. Treatment of behavioral disorders in Alzheimer's diseases. Rev Prat. 2011;61(7):939-44..

AD is the most common degenerative cerebral disease and the main cause of dementia in Western countries (50%-66%)3Scheltens PH, Leys D, Barkhof F, Huglo D, Weinstein HC, Vermersch P et al.

, and dental infections are common in these patients6Friedlander AH, Norman DC, Mahler ME, Norman KM, Yagiela JA. Alzheimer's disease: psychopathology, medical management and dental implications. J Am Dent Assoc. 2006;137(9):1240-51. http://dx.doi.org/10.14219/jada.archive.2006.0381
https://doi.org/10.14219/jada.archive.20...
. These infections are not often assessed during the treatment of AD but they need to be considered due to the risk of dissemination and the severe complications that they might cause7Aderhold l, Knothe; Frenkel G. The bacteriology of dentogenous pyogenic infections. Oral Surg Oral Med Oral Pathol. 1981;52(6):583-7. 10.1016/0030-4220(81)90072-4
https://doi.org/10.1016/0030-4220(81)900...
. Besides, dental infections are a cause of orofacial pain, which is a frequent complaint among the elderly. Despite recent evidence that oral infections such as periodontitis may be associated with AD, to our knowledge no study prior to this investigated the effects of dental treatment to patients with AD8Kamer AR. Systemic inflammation and disease progression in Alzheimer dsease. Neurology. 2010;74(14):1157-8. http://dx.doi.org/10.1212/WNL.0b013e3181d5df7f
https://doi.org/10.1212/WNL.0b013e3181d5...
.

Thus, the objective of this study was to evaluate patients with AD before and after dental treatment about their orofacial characteristics, as well as emotional, functional and cognitive aspects.

METHOD

In this descriptive not controlled open study, 29 (twenty-nine) patients with mild AD according to the diagnostic criteria of the National Institute for Communicative Disorders and Stroke – Alzheimer’s Disease and Related Disorders Association (NINCDS-ADRDA)9Mckhann G, Drachman D, Folstein M, Katzman R, Price D, Stadlan EM.

. The diagnosis was performed by a trained neurologist.

A dentist performed a complete orofacial assessment which included:

  • (i) Clinical questionnaire of orofacial pain, for the diagnosis of orofacial pain and oral infections, including a complete dental exam and the evaluation of the oral mucosa, tongue, and pain characteristics (location, intensity by the visual analogue scale – VAS, associated factors including tinnitus, bruxism, alleviating and worsening factors)1111 Siqueira SRDT, Nóbrega JCM, Valle LBS, Teixeira MJ, Siqueira JTT.

  • (iv) Dental and periodontal evaluation: DMFT (decayed, missing and filled teeth), plaque and gingival bleeding indexes (PI, BI), probing pocket depth (PPD), cementoenamel junction (CEJ) and clinical attachment level (CAL). The PI evaluated the oral hygiene, which was calculated according to the number of dental surfaces stained by a dental plaque disclosing agent multiplied by 100 and divided by the total number of surfaces, with reference value of ≤30%1414 American Academy of Periodontology. Parameter on chronic periodontitis with slight to moderate loss of periodontal support. J Periodontol. 2000;71(5 Suppl):853-5. http://dx.doi.org/10.1902/jop.2000.71.5-s.853

    . BI evaluated gingival inflammation, and was expressed by the number of bleeding surfaces after probing with a periodontal probe, multiplied by 100 and divided by the total number of surfaces, the reference value of which was ≤20%. The PPD was determined by the distance from the bottom of the pocket to the gingival margin, with reference value of >3 mm. By the periodontal evaluation, gingival hyperplasia or recession was identified. The CAL is calculated by the sum of PPD and CEJ, and its reference value is ≤3 mm (The American Academy of Periodontology, 1999)1414 American Academy of Periodontology.

The cognitive evaluation by the neurologist included the Mini Mental State Exam (cognitive deficit)1010 Brucki SMD, Nitrini R, Carameli P, Bertolucci PHF, Okamoto IH. Sugestões para o uso do Mini Exame do Estado Mental no Brasil. Arq Neuropsiquiatr. 2003;61(3B):777-81. http://dx.doi.org/10.1590/s0004-282x2003000500014

https://doi.org/10.1093/geronj/37.3.323...
. These questionnaires are part of the protocol of periodic evaluation of these patients to investigate respectively the progression of cognitive impairment and its impact on daily functional activities.

All patients were evaluated at three distinct stages:

1) First evaluation: before the dental treatment;

2) Second evaluation: after one month of the dental treatment;

3) Third evaluation: after 6 months of the second evaluation.

For ethical reasons, in the post-treatment evaluations the patients received further dental treatment if it was necessary.

Dental treatments

The dental diagnoses obtained after the dental evaluation previous to the treatment of the 29 patients are listed in Table 1. Twenty four patients completed the treatment and the first evaluation after the dental treatment (could not come due to sickness not related to AD or severe aggravation of cognitive status due to other reasons not related to the oral condition, and one died). At 6 months, 14 patients were re-evaluated (8 could not come due to sickness not related to AD and 2 died). The treatments performed are shown in Table 2. They were performed by the same dentist, and the most frequent were periodontal treatments (scaling, root planing and periodontal surgery), dental extractions and topic prescription of nystatin. Some of the treatments were made in the same patient or repeated in the post-treatment evaluations.

Table 1
Dental diagnoses in the initial evaluation of the patients (N=29).

Table 2
Dental treatments performed at each evaluation period.

Statistical analysis

Data were tabled and initially analyzed according to the distribution of quantitative variable by the Shapiro-Wilk test and Q-Q plots. Variables with normal distribution were analyzed by the analysis of repetitive measurements. The non parametric test for the rest of the variables was the MacNemar test. Correlation among the variables with normal distribution was tested with Pearson's for the variables with normal distribution. The level of significance was 5%.

RESULTS

After the initial dental treatment, frequency of pain and its intensity reduced [p=0.014 and p=0.040 respectively, (Table 3)]. There were no differences among the evaluations in bruxism, uncomfortable bite, tinnitus, generalized pain, headache or side of mastication. There was also a reduction in the chronic pain severity index (p=0.014) and of mandibular functional limitations (p=0.011) (Table 4). The oral health impact profile (OHIP) showed quality of life improvement after the dental treatment (p=0.009). There was a positive correlation between mandibular functional limitations, depression and anxiety indexes (p<0.001), which means that higher depression and anxiety indexes were correlated to more mandibular limitations (Table 4). Improvement was also detected in relation to the plaque index (p<0.001), BI (p<0.001) and PPD (p=0.024) (Table 5). Positive correlations were found between DMFT and PI (p<0.001), plaque index and maximum CAL (p=0.004), medium PPD and medium CAL (p<0.001), medium PPD and maximum CAL (p<0.001) and medium CAL and maximum PPD (p<0.001), which means that higher PI was associated with higher DMFT, CAL and PPD.

A significant reduction in the cognitive functional parameters by Pfeffer's questionnaire occurred after the dental treatment (Table 6). There was no correlation between these cognitive and functional indexes with any specific type of dental treatment or with an specific odontologic variable in this study.

DISCUSSION

AD is a progressive and disabling disease that has profound consequences for the lives of individuals. The aging of the global population is a factor that plays a role in the increase in the incidence and prevalence of dementia, and supports the need of functional improvement in the current quality of life of the patients4Almeida OP, Nitrini R. Demência. São Paulo: Fundo editorial BYK; 1995.. The health professionals involved in the assessment of them are looking for strategies beyond the treatment of AD for secondary morbidities to improve daily life activities, and in this context the oral health of these patients is one big issue. They have severe oral infections that cause several types of impairment6Friedlander AH, Norman DC, Mahler ME, Norman KM, Yagiela JA.

In this study, after the dental treatment, there was a clear evidence of pain relief (less orofacial complaints, myofascial pain, PI and periodontal infections). These were associated with the decrease in depression and anxiety indexes and better functional aspects by the Pfeffer's questionnaire (p<0.001), which can be correlated or not. As expected, the variables of periodontal disease were correlated between each other (CAL, PPD, BI, PI), and at the 1 month re-evaluation after the initial treatment several procedures were necessary in order to improve the oral health of the patients with limitations in their daily tasks, including oral hygiene. This was reflected in the increase of PI after 6 months, which shows the need of repetitive educational measures and treatments to keep the mouth free from recurrent infections in patients with a progressive disease such as AD.

It is possible that the pain observed at the initial evaluation was associated with the oral diseases that were treated due to the significant improvement in pain indexes within the follow-up period (p=0.014). Even the myofascial pain exhibited at the initial evaluation disappeared, and thus it was probably a consequence of the oral infections2525 Saczynski JS, Beiser A, Seshadri S, Auerbach S, Wolf PA, Au R.

. The DMFT index was statistically different after the dental treatment (p<0.001), which may be associated with the extractions that were necessary for some patients.

One important limitation of this study is the high loss of patients that we had for the post-treatment evaluations, which may have affected the results and thus this study should be considered preliminary. AD is a severe and progressive disease and it is difficult to follow these patients for a long time. However, to our knowledge, this was the first time that the effect of the dental treatment on emotional, functional and cognitive aspects was investigated. As a preliminary study, the sample size was not enough for multivariate analysis. These results are promising and indicate that the detailed relation between dental treatments and AD progression needs to be investigated in the future. There was a slight reduction in the cognitive score by MMSE, which was possibly associated with the progression of the disease in this 6-month period. It is not possible to know, based on this preliminary study, whether this index would have undergone more changes in case the patients were not treated, but some authors have discussed that periodontal infections may play a role in the cognitive impairment of these patients2222 Rethman MP. Inflammation in chronic periodontitis and significant systemic diseases. J Calif Dent Assoc. 2010;38(4):247-57.,2828 Siqueira SR, Nóbrega JC, Teixeira MJ, Siqueira JT.

https://doi.org/10.1111/j.1365-2842.2006...
.

In conclusion, after the dental treatment, a reduction of orofacial pain as well as the improvement of the mandibular function and in the periodontal indexes were detected in the patients with AD, conditions that were maintained until the last evaluation (after 6 months). The recovery of these patients’ oral health had a good impact on their quality of life and functional parameters.
