Abstract
OBJECTIVE The relationship between oral health and Crohn's disease is uncertain. Previous studies have yielded contradictory results, reflecting perhaps the different phenotypes of the disease. The aim of the present study was to describe and analyse the dental status of a group of patients with Crohn's disease (CD), considering the positions of the inflammatory loci and disease phenotype. METHODS In total, 47 patients with Crohn's disease (18 males and 30 females; mean age. 48.7 years; range, 23-61 years) were consecutively recruited to this study. Interviews and clinical examinations were performed to assess dental status, medication, smoking history, heredity of inflammatory bowel disease (IBD), duration of disease, oral mucosal manifestations of Crohn's disease. Furthermore, data on subjective health assessments and family status, along with medical histories from the patients were obtained through questionnaires. The disease phenotypes were assessed and classified according to the Montreal classification. The data on oral health status were first correlated with the Montreal classifications of IBD, and, thereafter, all the collected data were included in a multivariate generalised linear model. RESULTS The dental status of the patients was comparable to that of the Swedish average. No statistically significant associations were found between oral status and the different CD phenotypes. However, within the Montreal classification, there were significantly fewer teeth in those patients with perianal lesions than in those without such lesions, and there was a significant correlation between deeper pocket depth and problems with strictures and penetrations. No significant differences (p = .074) between the patients with CD (N = 47) and controls (N = 38) were found regarding the presence of oral mucosal lesions. CONCLUSION Dental health may be adversely affected in severe cases of CD whereas most of the remaining patients with CD appear to have a level of dental health that is comparable to that in the general population.

Abstract
Objectives Although bowel symptoms are often predominant, inflammatory bowel disease (IBD) patients can have several oral manifestations. The aim of this study was to investigate the prevalence of dental caries and periodontal disease in patients with Crohn’s disease (CD) and ulcerative colitis (UC) compared to an age and gender-matched control group of patients without IBD. Material and methods The DMFT (Decayed, Missing, Filled Teeth) scores and the DPSI (Dutch Periodontal Screening Index) of 229 IBD patients were retrieved from the electronic health record patient database axiUm at the Academic Centre for Dentistry Amsterdam (ACTA) and were compared to the DMFT scores and DPSI from age and gender-matched non-IBD patients from the same database. Results The total DMFT index was significantly higher in the IBD group compared to the control group. When CD and UC were analyzed separately, a statistically significant increased DMFT index was observed in CD patients but not in UC patients. The DPSI did not differ significantly between the IBD and non-IBD groups for each of the sextants. However, in every sextant, IBD patients were more frequently edentulous compared to the control patients. Conclusion CD patients have significantly more dental health problems compared to a control group. Periodontal disease did not differ significantly between IBD and non-IBD groups as determined by the DPSI. Clinical relevance It is important that IBD patients and physicians are instructed about the correlation between their disease and oral health problems. Strict oral hygiene and preventive dental care such as more frequent checkups should be emphasized by dental clinicians.

Abstract
OBJECTIVES Patients with inflammatory bowel disease have an increased risk of developing oral health problems. The aim of this study was to investigate whether oral diseases in these patients are related to inflammation of the intestine and if there is a correlation between inflammatory bowel disease-specific health-related quality of life (IBD-HR-QOL) and oral health problems. STUDY DESIGN The study was a cross-sectional survey and analysis of self-reported oral health of individuals with a stoma for Crohn's disease (CD), ulcerative colitis (UC), and treated colon cancer (CC). Validated international questionnaires were sent to members of the Stoma Federation of The Netherlands. Because there was an unequal distribution of male and female patients with CD and CC, data of 169 age-matched female patients with CD, UC, and CC with a stoma were analyzed. RESULTS Patients with CD had significantly more oral health problems compared with those with UC or CC. Patients with CD and UC both had significantly more gingival-related problems compared with patients with CC. There was a significant negative correlation between IBD-HR-QOL and oral health problems. CONCLUSIONS In the 3 distinguishable groups of patients with a stoma, patients with CD had an increased risk for oral health problems, independently from surgical removal of (a part of) the inflamed intestine, suggesting a general increased susceptibility of patients with CD for oral health problems.

ARQUIVOS DE GASTROENTEROLOGIA 2019; 56:118-123.

Abstract
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. Participants were submitted to a questionnaire (including demographic data, oral hygiene, eating habits) and a clinical observation with assessment of plaque index and Decayed, Missing and Filled Teeth index. Unstimulated/stimulated saliva was collected. Medical records, disease activity (Partial Mayo Score) and disease duration were collected. Laboratory data included salivary flow rates, salivary buffering capacity (CRT® buffer) and cariogenic bacteria count (Mutans streptococci and Lactobacillus spp) in saliva using the CRT® bacteria test (results: high or low counts). RESULTS Thirty UC patients were recruited. Oral hygiene routines were daily teeth brushing once or more (96.7%) and fluoride toothpaste (73.3%). Decayed, Missing and Filled Teeth index (mean 16.17±6.428) was not affected by the frequency of soft drinks, cakes, sweets and sugars between meals (P>0.2). Long-term disease showed a trend towards higher prevalence of caries (P=0.06). Most presented normal salivary flow rates, unstimulated (73.3%) and stimulated (60.0%), and high salivary buffering capacity (66.7%). Any association was found with age, gender, disease activity, disease duration and drug therapy. High Mutans streptococci and low Lactobacillus spp count were observed in 73.3% and 60% of patients, respectively. Patients with active disease (100%) and longer duration (88.9%) displayed higher Mutans streptococci count. CONCLUSION The prevalence of dental caries observed in UC patients was significant and did not seem to be influenced by their eating habits. The high prevalence of Mutans streptococci count may be a major risk factor for dental caries and may be looked as part of the UC dysbiosis. Dental care of UC patients should be planned according with this microbiota variation.

Abstract
Saliva functions in innate immunity of the oral cavity, protecting against demineralization of teeth (i.e. dental caries), a highly prevalent infectious disease associated with Streptococcus mutans, a pathogen also linked to endocarditis and atheromatous plaques. Gel-forming mucins are a major constituent of saliva. Because Muc19 is the dominant salivary gel-forming mucin in mice, we studied Muc19(-/-) mice for changes in innate immune functions of saliva in interactions with S. mutans. When challenged with S. mutans and a cariogenic diet, total smooth and sulcal surface lesions are more than 2- and 1.6-fold higher in Muc19(-/-) mice compared with wild type, whereas the severity of lesions are up to 6- and 10-fold higher, respectively. Furthermore, the oral microbiota of Muc19(-/-) mice display higher levels of indigenous streptococci. Results emphasize the importance of a single salivary constituent in the innate immune functions of saliva. In vitro studies of S. mutans and Muc19 interactions (i.e. adherence, aggregation, and biofilm formation) demonstrate Muc19 poorly aggregates S. mutans. Nonetheless, aggregation is enhanced upon adding Muc19 to saliva from Muc19(-/-) mice, indicating Muc19 assists in bacterial clearance through formation of heterotypic complexes with salivary constituents that bind S. mutans, thus representing a novel innate immune function for salivary gel-forming mucins. In humans, expression of salivary MUC19 is unclear. We find MUC19 transcripts in salivary glands of seven subjects and demonstrate MUC19 glycoproteins in glandular mucous cells and saliva. Similarities and differences between mice and humans in the expression and functions of salivary gel-forming mucins are discussed.

Abstract
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.

Abstract
OBJECTIVE To analyze the subgingival microflora composition of inflammatory bowel disease (IBD) patients with untreated chronic periodontitis and compare them with systemically healthy controls also having untreated chronic periodontitis. METHOD Thirty IBD patients [15 with Crohn's disease (CD) and 15 with ulcerative colitis (UC)] and 15 control individuals participated in the study. All patients had been diagnosed with untreated chronic periodontitis. From every patient, subgingival plaque was collected from four gingivitis and four periodontitis sites with paper points. Samples from the same category (gingivitis or periodontitis) in each patient were pooled together and stored at -70 °C until analysis using a checkerboard DNA-DNA hybridization technique for 74 bacterial species. RESULTS Multiple-comparison analysis showed that the groups differed in bacterial counts for Bacteroides ureolyticus, Campylobacter gracilis, Parvimonas micra, Prevotella melaninogenica, Peptostreptococcus anaerobius, Staphylococcus aureus, Streptococcus anginosus, Streptococcus intermedius, Streptococcus mitis, Streptococcus mutans, and Treponema denticola (P<0.001). CD patients had significantly higher levels of these bacteria than UC patients either in gingivitis or in periodontitis sites (P<0.05). CD patients harbored higher levels of P. melaninogenica, S. aureus, S. anginosus, and S. mutans compared with controls both at gingivitis and at periodontitis sites (P<0.05). UC patients harbored higher levels of S. aureus (P=0.01) and P. anaerobius (P=0.05) than controls only in gingivitis sites. CONCLUSION Our study showed that even with similar clinical periodontal parameters, IBD patients harbor higher levels of bacteria that are related to opportunistic infections in inflamed subgingival sites that might be harmful for the crucial microbe-host interaction.

Abstract
Detrimental effects of oral infections on general health have been known for almost 3000 years. Modern studies, however, have cast new light on the pathogenic mechanisms by which oral infections appear to link with morbidity and mortality. In particular, among the elderly, poor dental health seems to associate with all-cause mortality. This review aims to provide an overview of present knowledge of these issues, starting from dental bacteraemia, oral mucosal infections and problems of drug resistance and, briefly, discussing what is known about the link between oral health and some systemic diseases such as atherosclerosis and type-2 diabetes. The main conclusions are that scientific evidence is still weak on these interactions and that the elderly should be better taken into account when planning future studies. Functions of the body differ in the frail and diseased from those of the young. Consequently, novel prevention and treatment strategies should be developed and properly tested for combating oral infections in elderly populations. Specific suggestions for further research are outlined.

Abstract
OBJECTIVE Orofacial granulomatosis and the oral manifestations of Crohn's disease comprise many clinical features, of which stomatitis is one. The purpose of this study was to establish a role for Staphylococcus aureus in mucositis affecting some patients with orofacial granulomatosis or oral Crohn's disease. STUDY DESIGN Four patients (2 with orofacial granulomatosis and 2 with oral Crohn's disease), from a total of 450 patients examined over 10 years, had stomatitis involving the entire oral mucosa, from which S aureus was cultured by the oral rinse technique. These patients were treated with flucloxacillin or erythromycin. RESULTS A heavy growth of S aureus was isolated from the mouth of each patient. All 4 patients responded to treatment with flucloxacillin or erythromycin. CONCLUSIONS S aureus is a potential cause of panstomatitis in patients with orofacial granulomatosis or Crohn's disease. This infection responds rapidly to antimicrobial treatment.

Abstract
BACKGROUND Saliva protects the oral mucosa, inhibiting microbial overgrowth. Hyposalivation, therefore, induces multiple oral disorders, although treatment of hyposalivation is very difficult. METHODS A cholagogue, anethole trithione (AT) was administered to patients with symptomatic hyposalivation (xerostomia) caused by senile hypofunction (4 men and 17 women; senile group), medications (6 men and 17 women; drug group), and oral cancer therapy (two men and three women; cancer group). For control groups, an artificial saliva was administered to 45 patients consisting of senile hypofunction (10 men and 16 women), drug-induced xerostomia (3 men and 10 women) and oral cancer therapy-induced xerostomia (four men and two women). RESULTS Two weeks after administration of AT (6 tablets per day), both nonstimulated salivary flow rate (SFR) and stimulated SFR increased in a statistically significantly manner from 0.76 +/- 0.41 and 5.18 +/- 3.02 to 1.54 +/- 1.33 (P<0.05) and 9.07 +/- 4.10 mL/10 min (P<0.05), respectively. Of the three groups, the drug group showed the largest increases in both SFRs, from 0.90 +/- 0.54 and 6.29 +/- 4.12 to 1.69 +/- 1.65 and 12.09 +/- 5.10 mL/10 min (P<0.05 and P<0.02, respectively). Patients in the control group had almost constant SFRs. After AT administration, the salivary viscosity was, however, mildly decreased and concentrations of secretory-immunoglobulin A, lactoferrin, potassium, and chloride in nonstimulated saliva were almost constant. Corresponding with the increase of salivation, oral discomfort and inflammation were improved or resolved in 41 patients of the AT group within about 4 weeks, whereas improvement was observed in only nine patients of the control group. CONCLUSIONS These results indicate that AT sufficiently stimulates salivation and improves xerostomia.
