“…In contrast, no vancomycin resistance gene was present in any strain of endodontic origin, and only 1 isolate carried the gene conferring high-level gentamicin resistance, which is in agreement with previous reports on oral E. faecalis isolates (16,32,33). However, the present study observed a high prevalence of ermB and tetM genes in endodontic isolates, which agrees with previous findings showing that oral E. faecalis might represent a reservoir of resistance to tetracycline and erythromycin (16,(32)(33)(34).…”

“…Recently, poor oral hygiene has been reported to promote oral carriage of the antimicrobial-resistant microorganism Enterococcus faecalis in individuals with fixed orthodontic appliances [ 15 ]. Not only is E. faecalis reported to play a role in endodontic treatment failure [ 16 ], but there is also a well-known correlation between periodontal disease and E. faecalis, which can cause systemic infections as well [ 17 ].…”

Objective: To evaluate the effects of space maintainers on plaque accumulation, periodontal health and oral microflora. Subjects and Methods: The study participants comprised 38 patients aged 4-10 years requiring either fixed or removable space maintainers. Plaque index, gingival index, bleeding on probing index, candidal colonization and Enterococcus faecalis were recorded just before the application of space maintainers (T0) and during treatment at the 1st (T1), 3rd (T2) and 6th (T3) month. Results: The gingival and bleeding on probing index scores increased significantly (gingival index from 0.20 ± 0254 to 0.54 ± 0417 and bleeding on probing index from 7.18 ± 9.946 to 18.07 ± 14.074) in the regions with fixed space maintainers at T3 (p < 0.01). The mean Candida counts also increased (for removable appliances from 1.90 ± 3.638 to 1.98 ± 3.318, p < 0.05, and for fixed appliances from 4.25 ± 4.587 to 4.52 ± 4.431, p < 0.001). The salivary E. faecalis counts at T3 also increased significantly with the use of fixed and removable appliances (for removable appliances from 5.93 ± 2.65 to 85.53 ± 34.1 and for fixed appliances from 4.95 ± 2.94 to 123.59 ± 29.51, p < 0.001). A positive correlation was found between the plaque (r = 0.67), gingival (r = 0.76) and bleeding on probing index scores (r = 0.76) and the candidal colonization for the fixed space maintainers (p < 0.01, p < 0.001). Conclusions: In this study, both fixed and removable space maintainers led to an increase in the number of microorganisms in the oral cavity as well as to increases in the periodontal index scores. Patients should be informed that space maintainers may serve as a source of infection and that special attention must be given to their oral hygiene.

“…[ 2 ] The naturally acquired microflora is essential for the normal development of the host physiology, and contributes to the host defenses by excluding exogenous microorganisms. [ 3 ] The oral microflora is highly diverse, and more than 500 species of bacteria have been isolated from the oral cavity. [ 4 ]…”

“…Intestinal and skin microorganisms will regularly be introduced into the mouth, but they will not be able to compete successfully with the oral microorganisms for attachment sites and nutrients, and hence will be rapidly eliminated. [ 3 ]…”

Context:Onychophagia or habitual nail-biting is widespread among children and adolescents, between 10 and 18 years. Prevalence estimates range from 30% during childhood to 45% in adolescence. Nail-biting habit can result in autoinoculation of pathogens and transmission of infection between body parts.Aims:The purpose of the study was to evaluate the differences in prevalence of Enterobacteriaceae (E. coli and Enterobacter spp) in saliva samples from subjects with and without chronic nail-biting habit.Subjects and Methods:One hundred and twenty-two subjects with chronic nail-biting habit and 122 subjects with no oral habit were enrolled in the study. All subjects were aged 11-15 years. The saliva samples were collected by oral rinse technique, samples were studied microbiologically.Statistical Analysis Used:Two-tailed Student's t-test and Chi-square/Fisher's exact test were used to find the significance of study parameters between the groups.Results:Enterobacteriaceae were detected in the saliva samples of 80 of the 122 nail-biting subjects, whereas Enterobacteriaceae were detected in the saliva samples of only 10 of the 122 subjects who were not nail-biters. This difference in prevalence was statistically significant (P < 0.001).Conclusions:Our results suggest a higher carriage of Enterobacteriaceae in the individuals having nail-biting habits when compared to individuals with no habits. Further studies need to be done to know the prevalence of Enterobacteriaceae species in different age groups.
