Abstract

Systemic lupus erythematosus (SLE) is an autoimmune disease of the connective tissue, whose immune system attacks the body's own cells, resulting in inflammation and tissue damage. SLE can affect any part of the body, since autoantibodies (anti-DNA) have an affinity for DNA. Few studies have evaluated periodontal disease and dental interventions in patients with SLE, and no work has been found in the literature on periodontal surgery and its impact on the healing process, given that inflammatory processes are considered triggers for SLE activation, if not controlled. The objective of this work is to demonstrate, through a clinical case, the importance of dental practice in conjunction with medicine in assisting patients with SLE. A periodontal prevention protocol, free gingival graft surgery and orthodontic treatment were performed, which greatly favored the patient's function, aesthetics and quality of life. This is the first study that demonstrates the importance of lupus control according to rheumatological indexes and describes important dental aspects of the healing of patients with this systemic condition. Clinical interventions performed in patients with SLE require a multiprofessional approach, as several factors in the immune, repair and drug response must be considered for success, in addition to assessing other associated morbidities.

INTRODUCTION

Systemic lupus erythematosus (SLE) is a chronic, multisystemic inflammatory disease, of unknown cause and of an autoimmune nature, characterized by the presence of several autoantibodies [1]. It is a relatively rare disease with a greater predilection for women than for men, in a 10: 1 ratio [2]. SLE can affect any region of the body, considering that the autoantibody (anti-DNA) is able to affect any region that contains DNA, that is, any part of the body [1].

Because there is no cure, the disease is characterized by periods of activity and inactivity. The control of disease activity is performed mainly by the use of corticosteroids and other immunosuppressants. As it is a serious disease, it is extremely important that diagnosis and treatment be carried out as soon as possible. Serological tests can be used to assess the disease, the most important being the determination of anti-DNA antibodies and other criteria that are part of the American Academy of Rheumatology[3].

Among the parameters to check if the disease is active in the patient, the SLEDAI (Systemic Lupus Erythematosus Disease Activity Index) is the index most used in medical practice, as it is the most sensitive to changes in disease activity and is easy to apply. SLEDAI is a parameter measure for the prognosis of patients with SLE. There must be periodic monitoring of these patients to characterize the high risk for some patients who should be monitored more closely. Patients with SLEDAI ≤ 2 are considered to have no lupus activity [4]. These weights are added together resulting in a final score (maximum 105), the higher the higher the degree of disease activity [1].

The finding of irreversible damage or sequelae resulting from the disease can be measured using the SLICC (Systemic Lupus International Collaborating Clinics). This index can be stable or increase over time and has a maximum of 47 points [1].

Treatments performed with SLE patients require a multiprofessional approach, as several factors in the immune, repair and medication response must be considered, in addition to assessing other associated morbidities. There are few studies in the literature that mention periodontal treatment in patients with SLE [5-7]. Problems such as periodontal disease, gingival recession, malocclusion, among others, demonstrate a problem to these patients.

The objective of this work is to show, through a clinical case, the follow-up and dental assistance to a patient with SLE.

CLINICAL CASE REPORT

Female patient, 42 years old, white, with SLE, had chronic periodontal disease and generalized inserted gum loss, attended for dental treatment, as she reported frequent gingival inflammation, especially in the lower anterior teeth and uncomfortable with smile esthetics (Figure 1 and 2). In medical history, she reported having SLE for 18 years, having gone through several severe periods of disease activity, with a history of kidney involvement, anemia and several stages of hospitalization. 

The patient was using Tecnomed (8 tablets weekly), Prednisone 2.5mg, Enalapril 10mg, Folic Acid (1 comp./week), Ferrous sulfate and Miracalcium associated with the use of vitamin D.

 Figure 1: Initial oral clinical aspect of the patient with SLE. 

Initially, all data regarding rheumatological treatment were obtained. The patient had a SLEDAI = 2 and SLICC = 0. A SLEDAI up to 2 shows that the patient is inactive and the SLICC at zero, shows that the patient had no sequelae of the disease. The value of 2 corresponded to the anti-DNA that was reagent. Occasionally, patients may experience reactive anti-DNA values and other periods as non-reactive. One of the factors that most contributes to this activation of autoantibodies is exposure to sunlight. 

The patient reported that she had had greater exposure to the sun during this period, which justifies the fact that anti-DNA gave a reagent.

In view of the patient's stable SLE, scaling and root planing and oral hygiene guidance were initially planned.The initial plaque index was 93% and gingival bleeding index 17%. The patient was diagnosed with chronic moderate periodontal disease, after periodontal probing of six sites (V, MV, DV, L, ML, DL) per tooth. 

Periodontal treatment was performed consisting of scaling and root planing of all teeth with periodic maintenance so that the patient had improvement and awareness about the good control of plaque to start other dental treatments. 

At figure 3 we see the region between teeth 42 to 32 had limited gingival insertion and was aggravated by the insertion of the lip brake. Therefore, free gingival graft (EGL) surgery was planned, as proposed by several authors and we can see at figure 4 clinical appearance after scaling and root planing [8-12].

Initially, the concern was in relation to the patient's systemic condition, which after consultation with a rheumatologist, proved stable as mentioned earlier. However, there are no reports in the literature on the success or failure of regenerative surgery in patients with SLE. It is known that any inflammatory process can contribute to activate lupus activity, and the performance of a proposed gingival surgery could be a trigger. However, the patient needed periodontal intervention in order to improve the patient's oral appearance. The surgical area was delimited, a bed of connective tissue was prepared to receive the graft and the area for the graft was delimited in millimeter (mm) (Figure 5). After preparing the recipient bed, a map for the recipient site was made and the EGL was removed from the hard palate region for donation and suturing with absorbable 4-0 thread (Vycril - Johnson & Johnson). 

Figure 5: Demonstration of EGL adaptation in the receiving bed. 

The donor site and the graft are protected and the postoperative period was monitored for baseline (Figure 6), 7, 14, 21 days and subsequently analyzed at 3 months and finally at 5 years (Figure 7).

Figure 7: After: 5 years after EGL. 

Amoxicillin 500mg, 01 capsule every 8h for 7 days was prescribed. Anti-inflammatory was not recommended, as the patient has a history of kidney disease, although controlled and was using corticosteroids. 

After six months of EGL surgery and good plaque control, the patient was referred for orthodontic treatment. Because there are also no reports in the literature about orthodontic treatment in SLE patients after years of using corticosteroids and because the patient has periodontal disease with periodontal pocket in several places, a challenging treatment was planned together with the orthodontist, as the patient had anterior open bite in adulthood. 

There was a doubt about a higher risk of developing bone loss due to the chronic use of many years of corticosteroids. It was verified in some moments, even with minimal force applied by the orthodontist, tooth mobility that questioned the patient's prognosis. Several months of frame stability, without the application of orthodontic force during maintenance, were necessary. 

The patient had already sought treatment in other clinics, but without success, as they were reluctant to treat her due to the severity of the case and the presence of the disease Lupus. 

Radiographic examinations, photographs, cephalometric analyzes and study model were requested prior to orthodontic treatment. After clinical evaluation and complementary exams, the patient's malocclusion was diagnosed and orthodontic planning was performed (Figure 8 and 9).

On examination, the patient had: symmetrical face, vertical growth tendency, enlarged lower third of the face, absence of lip sealing and convex profile. Normal lip and lingual brake, normal size tongue and interposition at rest, when swallowing and speaking. The shape of the upper and lower arch was normal, the occlusion had a molar ratio of ¾ Class II of Angle and a canine ratio of ½ class II on the right side and on the left side. She had an anterior open bite of more than 10 mm, vestibularized upper and lower anterior incisors and with lower diastemas. 

The fixed orthodontic treatment was proposed with the objective of closing the anterior open bite with intrusion of the posterior teeth, extrusion of the anterior teeth, initiating the bonding of the orthodontic appliance through the lower arch (Figure 10).

 Figure 10: Smile after bonding lower arch. 

Due to the difficulty of the patient to attend with the appropriate frequency for dentist appointments, it was necessary to do the extraction of teeth 15 and 25 (Figure 11). This facilitated the closing the spaces of the extractions, helping to close the open bite, displacing the upper incisors.

The proposed treatment aimed to grant the patient the best benefit within the limitations of tooth movement. Therefore, the movement was smooth, with light forces aiming at the maximum preservation of the teeth and the bone level, this caused the orthodontic treatment to take 4 years (Figure 12), a longer time than that predicted in the literature for periodontal patients [13,14]. Whenever possible, it is necessary to shorten the duration of orthodontic treatment to prevent worsening of periodontitis.

 Figure 12: Clinical aspect being completed after 4 years of orthodontic treatment. 

During orthodontic treatment, panaroamic radiographs were taken to assess the evolution and control of movement and bone level (Figure 13). Some clinical interventions were made, such as periodic periodontal scrapes; hygiene instructions; endodontics of the tooth 27, where there was no regression of the periapical lesion - endo-perioid lesion - after endodontic treatment; extraction of teeth 17, 27, 28 and 38 and exchange of restorations of teeth 14 and 24 for indirect restorations (ceromer onlay).

After the case was completed, the fixed appliance was removed and Hawley-type mobile retainers were made in both arches. The patient was referred to periodontics for completion of surgical periodontal treatment. After the periodontal treatment, the fixed retention was placed to prevent relapse.

DISCUSSION

Treatments performed on patients with systemic lupus erythematousus require a multidisciplinary and multiprofessional approach. SLE must be accompanied by a rheumatologist and there is a need for frequent drug treatment in order to keep the disease inactive [3,15,16]. In this case report, the patient was using control medications with minimal dosage, as she had her SLE controlled, without major systemic involvement. 

The Dental Surgeon requires team monitoring in order to provide a better therapeutic approach and to avoid confusion in the diagnosis, since there are several similar aspects among other types of lupus and even other oral diseases [7,17,18]. Antibiotic therapy associated with the surgical procedure was used, due to the risk that the patient has of developing some type of infection, as she is considered an immunosuppressed patient due to the frequent use of corticosteroids. 

Proof of predilection for women is highly demonstrated in studies with the disease. Studies reporting men with SLE are rare [11,16]. 

SLEDAI and SLICC are arguably methods of characterizing disease activity [1,4]. It is always necessary to use them for the evaluation of SLE. In case of positive evaluation, inactivity of the disease, it is allowed to do any type of procedure necessary for the patient's health, including oral, even surgery. 

Despite the low prevalence of oral lesions and poor periodontal conditions in patients with SLE [7] special care is needed for these patients due to the low immunity they have, which makes them more susceptible to the acquisition of other diseases. Also taking into account the inflammatory process of periodontal disease in association with lupus activity and the fact that SLE patients are immunosuppressed [6,19]. 

The high rate of plaque and the low rate of gingival bleeding is in agreement with several authors in the literature [4,19]. This is because the chronic use of corticosteroids prevents the typical reaction of the inflammatory condition. However, the bacteria are still present and continue to degenerate the periodontal apparatus [20]. 

The method used in this case report to solve the patient's gingival recession is one of the most chosen among the surgeries that solve this problem. It is possible to predict a satisfactory result [9,10,11]. Even in patients with SLE, if the disease is controlled, the use of the correct medications can even decrease the amount of periodontal pockets present in patients [21]. 

The literature does not report orthodontic treatments in patients with systemic lupus erythematosus. In our study, we observed a longer time than that predicted in the literature for periodontal patients in orthodontic treatment [13,14] in a patient with SLE and periodontal disease. Due to the activity and inactivity that SLE patients present, the frequency of consultations ends up being more spaced and increasing the expected time. Whenever possible, it is necessary to shorten the duration of orthodontic treatment to avoid worsening periodontitis. 

There are few studies in the literature that mention periodontal treatment in patients with SLE. Therefore, this case report is important to alert the need for knowledge in the care of these patients, even avoiding prejudice against the disease.

CONCLUSION

Through this case report, it could be observed that health professionals need to know about SLE to obtain the correct diagnosis and offer the correct treatment to SLE patients.

It is necessary that the patient is in adequate conditions for the procedure, characterized by a period of inactivity of the disease and evaluation of several systemic factors, since the disease activity associated with invasive procedures can accentuate the inflammatory damage of lupus.

The patient must be under drug control and rheumatological follow-up, allowing any dental procedure to be performed on patients, even surgical ones, such as free gingival graft. And more research is needed on this topic for a better diagnosis and treatment of patients with systemic lupus erythematosus.
