Final answer:
The correct answer is increased lacrimation, as Sjögren's syndrome usually results in decreased tear production, not an increase.
Step-by-step explanation:
A patient diagnosed with Sjögren's syndrome may have a marked increase in all of the following except: increased dental caries, increased/inflamed salivary glands, and increased keratoconjunctivitis sicca. The correct answer is increased lacrimation. Sjögren's syndrome is an autoimmune disorder that typically decreases the body's ability to produce tears and saliva, leading to dry mouth and dry eyes. In this condition, the immune system mistakenly attacks the exocrine glands, including the salivary glands. This autoimmune response often leads to decreased lacrimation (tear production) instead of increased lacrimation, contributing to a symptom known as keratoconjunctivitis sicca, or dry eye syndrome.
