Sjögren's syndrome is an autoimmune condition that affects the body’s moisture-producing glands.1 It is the third most common rheumatic disorder after rheumatoid arthritis and systemic lupus erythematosus.2 Sjögren's is often identified by its two most common symptoms—dry eyes and dry mouth. Other symptoms can include profound fatigue, chronic pain, major organ involvement, neuropathies, and increased incidence of lymphomas (5%). The prevalence occurs in up to 3% of the population.
The mechanism underlying the development of Sjögren's is the destruction of the epithelium of the exocrine glands, as a consequence of abnormal B cell and T cell responses to autoantigens.3 The disease was described in 1933 by Swedish Ophthalmologist Dr. Henrik Sjögren, after whom it is named; however, a number of earlier descriptions of people with the symptoms exist. Between 0.2% and 1.2% of the population are affected with this autoimmune disease, with half having the primary form and half the secondary form. Females are affected about 10 times as often as males, and the disease commonly begins in middle age with a mean age of diagnosis at 54.4 The prognosis is largely dependent on systemic components, with pulmonary involvement resulting in a two- to four-times greater mortality risk.4
Sjögren's can be difficult to diagnose, because the symptoms can mimic those caused by other diseases. Diagnosis requires a number of clinical and pathological features. Blood tests for antibodies, eye tests for dryness, and imaging or biopsy of salivary glands can be used for a final diagnosis. Dentists and oral pathologists serve an important role in diagnosis, since common diagnostic criteria include adequate biopsy of minor salivary glands. Lymphocytic focal sialadenitis, which describes the presence of dense aggregates of lymphocytes, is consistent with Sjögren's syndrome.5
Case study
A 35-year-old female patient presented with esthetic concerns after a diagnosis of Sjögren's syndrome. Patient complaints included short appearance of teeth, stained teeth, and worn incisal edges (figures 1–2). Loss of vertical dimension of occlusion was noted as evidenced by shortened coronal structure and bilateral angular cheilitis (figure 3).
Upon clinical and radiographic examination, it was determined that the patient had a combination of caries, inflamed gingiva from desiccation, and loss of vertical dimension (figure 4). Xerostomia and insufficient home care were implicated in the patient’s elevated caries rate, as well as the presence of implants leading to implant-induced caries.
After the first phase consisting of caries control and periodontal treatment, the patient received soft- and hard-tissue crown lengthening by laser (figure 5). After an eight-week healing period, full-mouth cosmetic restorations were placed, which included full- and three-quarter-coverage e.max crowns and zirconia bridges (figures 6–7).
Following therapy, the patient was seen every three months for hygiene recare and to evaluate the status of caries and gingival inflammation. CariFree CTx4 Gel, home-administered sodium fluoride trays, and interproximal irrigators were given to the patient to increase resistance to caries. Oral hygiene instruction was an integral part of the recare visits and proved to be valuable in maintaining the patient’s results two-and-a-half years later (figure 8).
