Abstract

Objective: To evaluate a possible association between wrist and periodontal destruction in rheumatoid arthritis, and between periodontal destruction, dry mouth, and labial salivary gland biopsy and the contribution of genetic factors (the shared epitope (SE) and IL1B (+3954) or TNFA (−238 or −308) gene polymorphisms).

Methods: 147 patients with rheumatoid arthritis were enrolled. Periodontal damage was defined according to the Hugoson and Jordan criteria on panoramic dental x rays. Typing for the SE and cytokine polymorphisms was undertaken by enzyme linked oligosorbent assay. Odds ratios (OR), relative risk (RR), and χ2 values were calculated to quantify associations.

Results: An association was observed between wrist and periodontal bone destruction (χ2 = 11.82; p<0.001): 63 patients had both wrist and periodontal destruction, 31 had wrist destruction alone, 20 had periodontal destruction alone, and 33 had no destruction at either site. An association was seen between a positive labial salivary gland biopsy and periodontal bone destruction (RR = 2.73 (95% CI, 1.35 to 5.51), p<0.01, n = 41) or wrist bone destruction (RR = 4.52 (1.96 to 10.45), p<0.001, n = 41). The SE was associated with wrist bone destruction (OR = 2.5 (1.16 to 5.42), p<0.05) and periodontal bone destruction (OR = 2.2 (1.04 to 4.84), p<0.05). No association was found between the selected cytokine polymorphisms and bone destruction.

Conclusions: A strong association was found between wrist and periodontal bone destruction. The destruction risk was further increased in patients with sicca syndrome. The SE appears to be a severity genetic marker for both wrist and periodontal bone destruction.
