Objective:
The present study tested the hypothesis that patients with Crohn's disease (CD) have a higher prevalence and risk for caries compared to people without CD.
Material And Methods:
Patients with CD were divided into groups; 71 patients (50.7 ± 13.9 years) who had gone through resective intestinal surgery and 79 patients (42.0 ± 14.4 years) who had not. The patients were compared to 75 controls (48.6 ± 13.4 years) regarding DMF-T and DMF-S, Lactobacilli (LB), Streptococcus mutans (SM), salivary flow and dental plaque. Statistical methods including ANOVA or Chi-square test for calculation of demographic differences between groups, analysis of covariance (ANCOVA) to compare the clinical variable and Post hoc analyses were done with Fischers Least Significant Difference test or Chi-square. Non-parametric Spearman's correlation matrix coefficient was estimated between clinical variables and disease duration.
Results:
CD patients who had been subjected to resective surgery had a higher DMF-S score (50.7 versus 36.5; p = 0.01) compared to the control group after adjusting for age, gender and smoking. These patients had higher counts of SM (1.5 versus 0.9; p = 0.04) and LB (10000.0 versus 1000.0; p = 0.01), and more dental plaque (53.7 versus 22.6; p = 0.001). CD patients reported a more frequent consumption of sweetened drinks between meals compared to controls (p = 0.001).
Conclusions:
The present study shows that patients with CD who had undergone resective surgery had a higher DMFs score, and higher salivary counts of Lactobacilli and Streptococcus mutans compared to the control group.

01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
