ARE CARIOGENIC BACTERIA THE MAJOR RISK FACTOR TO DENTAL CARIES IN PATIENTS WITH ULCERATIVE COLITIS?

Background: High prevalence of dental caries in ulcerative colitis (UC) has been attributed to diet and changes in salivary environment.

Objective: We aimed to characterize the prevalence of dental caries, salivary flow rates, salivary buffering capacity and cariogenic bacteria counts of Mutans streptococci and Lactobacillus spp and to evaluate their relationship with drug therapy, disease activity and duration.

Methods: A cross-sectional study was performed with UC patients followed in a tertiary center.

Oral mucosa lesions and oral symptoms in inflammatory bowel disease patients.

Background: Inflammatory Bowel Disease is known for its extra intestinal manifestations, the oral cavity is no exception.

Objectives: The aim of this study was to evaluate the association between Inflammatory Bowel Disease and oral mucosa lesions and symptoms, and complementary to evaluate their possible relation with oral hygiene, smoking habits, drug therapy, duration and activity of the disease.

Methods: Patients were selected from the Gastroenterology Clinic of a Portuguese tertiary referral hospital.

Noise-induced gastric lesions: a light and electron microscopy study of the rat gastric wall exposed to low frequency noise.

Context: Only a few studies evaluated the digestive alterations caused by low frequency noise (LFN) and most focused only on mucosal alterations.

Objectives: To investigate the morphological injury of LFN-exposed gastric wall, beyond the epithelial layer.

Methods: Wistar rats were exposed to low frequency noise (LFN), during increasing periods, 1 to 13 weeks.
