“…In addition, although all children declared to brush their teeth twice a day, the reported duration of the brushing considered effective for a good dental hygiene (≥ 2 minutes) was statistically significant higher in diabetic group in good metabolic control compared to diabetic in bad metabolic control and non-diabetic group. This finding might also contribute to explain the caries figure in the studied populations [ 47 ].…”

AimTo evaluate the caries prevalence and related variables in Type 1 diabetic and non-diabetic children and among the diabetic children according to their metabolic status.MethodsSixty-eight diabetic and 136 non-diabetic children, matching by gender and age (4–14 years) were enrolled. The diabetic children were divided: a) 20 children in good metabolic control (Hb1ac≤7.5) and b) 48 children in bad metabolic control (Hb1ac>7.5). Dietary and oral hygiene habits were investigated. Caries status was registered using the International Caries Detection and Assessment System. Oral microflora was analysed using the checkerboard DNA-DNA hybridisation method. Plaque acidogenicity was recorded after a sucrose rinse.ResultsSugared beverage and snack intake was higher in diabetic group compared to non-diabetic group (p = 0.03 and p = 0.04, respectively) and in subjects in bad metabolic control (p = 0.03 and p<0.01, respectively). Oral hygiene habits were similar, except for the use of fluoridated adjuvants, higher in non-diabetic children (p = 0.04). No statistically significant differences were observed regarding caries figures, but a higher number of caries free subjects was found in diabetic subjects in good metabolic control (p<0.01). Significant difference for the main cariogenic bacteria was found between diabetic and non-diabetic subjects (p<0.05). The pH values showed statistically significant differences between diabetic and non-diabetic subjects and between diabetic subjects in good and bad metabolic control (p<0.01).ConclusionsDiabetic children in good metabolic control might even be considered at low caries risk, while those in bad metabolic control showed an oral environment prone to a high caries risk.

“…Furthermore, we also examined the 3D architecture of multispecies biofilms formed during exposure to sucrose or glucose+fructose on enamel specimens placed in the mouth using a modified intra-oral caries model 20, 21, 22 according to approved institutional review board (IRB) protocol at Indiana University (IRB #1407637739). Briefly, subjects wore their partial denture with two flattened and polished enamel specimens imbedded in the buccal surface of the posterior denture teeth for 14 days.…”

Biofilm three-dimensional architecture influences in situ pH distribution pattern on the human enamel surface

et al. 2017

To investigate how the biofilm three-dimensional (3D) architecture influences in situ pH distribution patterns on the enamel surface. Biofilms were formed on human tooth enamel in the presence of 1% sucrose or 0.5% glucose plus 0.5% fructose. At specific time points, biofilms were exposed to a neutral pH buffer to mimic the buffering of saliva and subsequently pulsed with 1% glucose to induce re-acidification. Simultaneous 3D pH mapping and architecture of intact biofilms was performed using two-photon confocal microscopy. The enamel surface and mineral content characteristics were examined successively via optical profilometry and microradiography analyses. Sucrose-mediated biofilm formation created spatial heterogeneities manifested by complex networks of bacterial clusters (microcolonies). Acidic regions (pH<5.5) were found only in the interior of microcolonies, which impedes rapid neutralization (taking more than 120 min for neutralization). Glucose exposure rapidly re-created the acidic niches, indicating formation of diffusion barriers associated with microcolonies structure. Enamel demineralization (white spots), rougher surface, deeper lesion and more mineral loss appeared to be associated with the localization of these bacterial clusters at the biofilm-enamel interface. Similar 3D architecture was observed in plaque-biofilms formed in vivo in the presence of sucrose. The formation of complex 3D architectures creates spatially heterogeneous acidic microenvironments in close proximity of enamel surface, which might correlate with the localized pattern of the onset of carious lesions (white spot like) on teeth.

“…Students may have bad oral health practices due to their busy teaching and learning schedule. [13][14][15] Insufficient time may cause them not to regularly brush their teeth and neglecting other important OH practices. Although antimicrobial mouthwashes can help reduce numerous oral infections, caries and plaque which can lead to gingivitis and gum diseases.…”

“…Although antimicrobial mouthwashes can help reduce numerous oral infections, caries and plaque which can lead to gingivitis and gum diseases. [14][15][16] But yet continuity in adopting good practices to attain OH is recommended by the American Dental Association (ADA). 13 Regular and gentle brushing of the tongue can also help in removing various germs and maintain freshens of the breath.…”

Objectives: This study aimed to determine sociodemographic correlates of practice towards oral hygiene (OH) among university students in a private university. Methods: A cross-sectional study was performed among university students in Malaysia using a prevalidated questionnaire. The convenient stratified sampling method was adopted to recruit participants from four main faculties of a private university. The Statistical Package for Social Science (SPSS) Version 24.0 was used to analyze the data. Univariate and multivariate analyses were performed to determine the correlates of practice of OH among the study participants. Results: Out of a total of 324 participants, female students had far-good practice towards OH than males. The final year students showed better OH practice than the pre-final years. Among the studied races, the Chinese students had the highest percentage of adequate practice than the rest. Overall, this study found that most of the students had fair to good practice towards OH. Conclusion: Multiple logistic regression analyses showed that statistically significant differences (p<0.05) were present among the six demographic variables. The current study found that age groups, race, faculty, year of education, parents' education, and healthcare professionals in the family were the sociodemographic correlates of practice towards OH among the university students in Malaysia.
