RESUMO
STATEMENT OF PROBLEM: Marginal integrity and internal adaptation are key to the long-term success of porcelain laminate veneers. Evidence for their marginal and internal fit is unclear, and the factors affecting such fit have not been identified. PURPOSE: The purpose of this systematic review and meta-analysis was to summarize the scientific literature assessing the effects of various parameters on the marginal and internal fit of porcelain laminate veneers. MATERIAL AND METHODS: An electronic search was conducted to identify all relevant published articles on the fit accuracy of ceramic veneers between January 2000 and June 2021 in the PubMed-MEDLINE, Scopus, Embase, Google Scholar, and Web of Science databases. Information, including the study outcomes, in terms of the mean marginal gap, internal gap, and absolute marginal discrepancies of porcelain laminate veneers, was extracted from the selected studies. The inverse-variance random effects model was used to analyze the pooled results and estimate the overall effect based on the heterogeneity of studies (α=.05). RESULTS: Twenty-one studies were selected for analysis, 2 clinical and 19 in vitro. The risk of bias was "medium" for most studies (19 of 21), and only 2 studies were classified as "high risk." A mean difference of -4.53 µm (95% CI: -21.46 to 12.41) was found, with no statistically significant difference in marginal gap between the pressed and milled fabrication modes (P=.600). As for the internal gap, significant differences were found (mean difference=-40.56 µm; 95% CI: -76.54 to -4.58), with pressed veneers performing better (P=.030). Butt joint preparation design produced significantly (P=.002) lower marginal gaps than the palatal chamfer (mean difference=-14.02 µm; 95% CI: -23.07 to -4.98). CONCLUSIONS: No significant differences were found between the pressed and milled porcelain laminate veneers for marginal gap, but for the internal gap, the differences were significantly in favor of the pressed type. The butt joint veneer preparation design was significantly better than the palatal chamfer design in terms of marginal fit.
RESUMO
BACKGROUND: It is hypothesized that periodontal status is compromised and whole salivary (WS) interleukin (IL)-15 and IL-18 levels are higher among cigarette-smokers and electronic-nicotine-delivery-systems (ENDS)-users than never-smokers. The aim of the present case-control study was to compare the periodontal status and WS IL-15 and -18 levels among cigarette-smokers, ENDS-users and controls (never-smokers). METHODS: Participants were divided into 4 groups as follows: Group-1:Current cigarette-smokers; Group-2:ENDS-users; Group-3:Never-smokers with periodontitis; and Group-4: Never-smokers without periodontitis. Demographic data was collected and plaque index (PI), gingival index (GI), probing-depth (PD), clinical attachment-loss (AL), and marginal bone loss (MBL) were measured. Number of missing teeth were recorded and WS IL-15 and IL-18 levels were determined. Group-comparisons were done and P < 0.01 was selected as an indicator of statistical analysis. RESULTS: Nineteen, 18, 19 and 19 individuals were enrolled in groups 1, 2, 3 and 4, respectively. Scores of PI, clinical AL, PD, and number of missing-teeth were elevated in groups 1(P < 0.001), 2 (P < 0.001) and 3 (P < 0.001) than -4. Scores of PI, clinical AL, PD, MBL and missing teeth were comparable among patients in groups 1, 2 and 3. Levels of IL-15 and IL-18 were elevated in groups 1 (P < 0.001) and 2 (P < 0.001) than groups 3 and 4. The levels of IL-15 and -18 were higher in Group-3 than in Group-4 (P < 0.001). CONCLUSION: Clinically, cigarette-smokers and never-smokers demonstrate similar periodontal statuses; however, WS immunoinflammatory biomarkers (IL-15 and -18) are elevated in these individuals than non-smokers.

BACKGROUND: The aim was to assess the association between levels of advanced glycation endproducts (AGEs) in the gingival crevicular fluid (GCF) and periodontal parameters among cigarette-smokers and waterpipe-users. METHODS: Self-reported cigarette-smokers; waterpipe-users and never-smokers were included. Demographic data was recorded using a questionnaire. Periodontal parameters (plaque index [PI], gingival index [GI], clinical attachment loss [AL], probing depth [PD], and marginal bone loss [MBL]) were assessed in all groups. The GCF samples were collected using standard techniques and assessed for AGEs levels using enzyme-linked immunosorbent assay. Sample-size estimation was done and group-comparisons were done. Correlation between levels of GCF AGEs levels and periodontal parameters was assessed using a logistic regression model. Level of significance was set at P < 0.01. RESULTS: Eighty-two individuals (28 cigarette-smokers, 28 waterpipe-users and 26 never-smokers) were included. There was no difference in mean ages of all patients. Cigarette-smokers had a smoking history of 5.1 ± 0.2 pack years and waterpipe-users were using waterpipe for 4.4 ± 0.6 years. There was no statistically significant difference in PI, GI, clinical AL, PD and MBL in all groups. Levels of AGEs were significantly higher among cigarette-smokers (P < 0.001) and waterpipe-users (P < 0.001) than never-smokers. There was no significant correlation between levels of GCF AGEs levels and periodontal parameters in all groups. CONCLUSION: Clinical periodontal status of individuals with a short history of cigarette-smoking and waterpipe-usage may appear similar to never-smokers. On a molecular level, cigarette-smoking and waterpipe-users express raised levels of AGEs than never-smokers that sirens about the ongoing yet latent periodontal inflammatory process.

OBJECTIVES: To systematically review and evaluate the effects of different types of attachments, implant numbers and loading protocols on the peri-implant mucosa of implant-supported overdentures (ISODs). BACKGROUND: The impact of peri-implant tissue health on the ISOD treatment outcome is unclear, and current evidence is inadequate on this aspect. MATERIALS AND METHODS: A systematic literature search for randomised controlled trials or prospective studies was conducted in indexed databases from 1995 to April 2020. The focused question was as follows: How does the peri-implant mucosa respond to implant-supported or implant-tissue-supported complete overdentures based on different types of attachments, implant numbers, and loading protocols, in terms of clinical outcomes achieved [plaque index (PI), gingival index (GI), probing pocket depth (PD) and bleeding index (BI)]? A random- or fixed-effects model was applied to measure the significance of standardised mean differences (SMD) of PD between the groups. RESULTS: Seventeen studies met the eligibility criteria. The SMD for PD between splinted/bar and unsplinted/stud attachments was 0.10 mm (95% CI: -0.27 to 0.47; P = .60) and between 2- and 4-implant groups was 0.15 mm (95% CI: -0.16 to 0.45; P = .34), which were not statistically significant. Significant difference (P = .003) was observed between immediate/early loading and delayed loading (SMD = 0.46 mm [95% CI: 0.16 to 0.75]). CONCLUSIONS: Probing depth for the immediate loaded implants was significantly higher than for the delayed loading group. No attachment type, implant number or loading protocol seemed to have a clear advantage over the other, in terms of other peri-implant mucosal outcome measures.

OBJECTIVES: This study evaluates the effect of using miswak chewing sticks on dental plaque, selected oral microbiota and gingival inflammation among patients with gingivitis. METHODS: The study was a single-centre, single-examiner blind, randomized, crossover study. Twenty healthy participants were randomly assigned into two equal groups (n = 10). Group 1 were instructed to use both toothbrush and miswak (TB+M) for the first 2 weeks from baseline (T1) and only toothbrush for the next 2 weeks (T2); and Group 2, only TB during T1 and TB+M during T2. Gingival index (GI), plaque index (PI) and bleeding on probing (BOP) were evaluated at baseline (T0), T1 and T2 visits. Supra-gingival plaque samples were taken at T0, T1 and T2. Quantification of Streptococcus mutans and Aggregatibacter actinomycetemcomitans from the supra-gingival plaque samples were performed by real-time polymerase chain reaction (qPCR). RESULTS: The scores of GI, PI and BOP had significantly improved for both groups between T0 and T1. A significantly greater reduction in the percentage of sites with BOP was observed for TB+M group compared with TB group (TB+M group: from 32.2 to 14.93; TB group: from 34.00 to 26.0; p = .014). At T2, TB+M group had significant improvements (p < .05) in the PI, GI and BOP scores compared with TB group. There was no significant difference in the microbial counts of S. mutans and A. actinomycetemcomitans between the two groups at the end of the study period. CONCLUSIONS: Oral hygiene and gingival health may be improved by complementing miswak chewing sticks with toothbrushing.

BACKGROUND: This study aims to explore the difference in the utilization pattern of dental services among pregnant, post-partum and six-month post-partum women. METHODS: This cross-sectional questionnaire survey was performed at two maternity and child care hospitals in India that primarily cater to middle and low income communities. Data were collected from 3 groups: 1) pregnant women in their first trimester; 2) post-partum women (< 48 h after delivery); and 3) six-month post-partum women. The primary outcome of interest was dental service utilization during pregnancy. Self-perceived oral health (SPOH) was calculated based on the four global dimensions- knowledge, function, quality of life and social. Multiple logistic regression analysis was carried out to assess the effect of each independent variable after adjustment for the effect of all other variables in the model. RESULTS: Responses of 450 (150 pregnant, 150 post-partum and 150 six-month post-partum) women were analyzed (response rate = 72%). Significant differences in the dental attendance pattern was observed between the study groups (p < 0.01). Dental attendance among pregnant and six-month post-partum women were 60 and 75%, respectively, however, only about 15% of the post-partum women reported to have sought dental care within the 6 months prior to the study. Post-partum women had the highest SPOH scores, indicating poor self-perceived oral health, followed by pregnant and then six-month post-partum women, which was statistically significant (p < 0.05). A significantly higher percentage of post-partum women reported to have poor oral and general health, as compared to both, pregnant and six-month post-partum women (p < 0.01). Higher percentage of women reporting 'good' oral and general health had sought dental care compared with others (p < 0.01). After adjusting for all the other variables in the model, women with lower levels of education (ORa = 1.42; 95% CI: 1.01-2.00), women with poor self-perceived oral health (ORa = 1.08; 95% CI: 1.02-1.14) and post-partum women (ORa = 0.15; 95% CI: 0.09-0.24) were found to be less likely to seek regular dental care. CONCLUSION: Pattern of dental service utilization among women in this population varied according to their pregnancy status, level of education and self-perceived oral health.

BACKGROUND: Health literacy has been found to be a strong predictor of an individuals' health, health behavior and health outcomes. Lower literacy has been linked to problems with the use of preventive services, delayed diagnoses of medical conditions, poor adherence to medical instructions, poor self-management skills, increased mortality risks, poor health outcomes, and higher health care costs. The aim of this study is to determine the relationship between oral health literacy (OHL) and oral health status among patients attending a University-affiliated dental clinic. METHODS: A convenience sample of participants was drawn from the dental patients presenting at School of Dental Medicine (SODM), Case Western Reserve University (CWRU). Information about the subjects' demographic details, income, family size, insurance type and smoking history were collected using a data collection form. Data about the patients' periodontal and caries risk assessment, caries experience and periodontal status was extracted from the patients' electronic dental records. The Comprehensive Measure of Oral Health Knowledge (CMOHK) was used to record the oral health literacy. The median CMOHK score was 18, and this was used to categorize the sample into limited OHL (≤18) and adequate OHL (> 18) groups. A multivariate logistic regression model was built to examine the associations between the various independent variables and OHL levels. RESULTS: Data of 150 respondents were analyzed. More than half of the participants were female (55.3%) and the majority were Caucasian (60%). The average age of participants was 53.3 years [standard deviation (SD) 16.8]. Higher percentage of African Americans and individuals with low education had limited OHL levels (p < 0.05). The mean decayed, missing, and filled teeth (DMFT) score for this population was 7.33 ± 2.68. Subjects with limited OHL had significantly higher mean values for missing teeth (p < 0.05) and lower mean values for filled teeth (p < 0.05) as compared with subjects with adequate OHL Significantly, higher percentage of subjects with limited OHL had severe periodontitis as compared with those with adequate OHL (p = 0.04). Multivariate analysis found that the periodontal status was significantly associated with the OHL scores (p = 0.015). CONCLUSION: Subjects with limited OHL levels had poorer periodontal health. Improving the OHL of patients may help in the efforts to improve the adherence to medical instructions, self-management skills and the overall treatment outcomes. Future research could focus on assessing the impact of OHL interventions on the oral health, which could be valuable for clinical practitioners.

Aim The purpose of this study was to assess the difference in the oral health related quality of life (OHRQoL) and the oral health status between pregnant and non-pregnant women. Methods This cross-sectional study included 150 pregnant women (mean age 23.8 ± 3.01) and 150 non-pregnant women (mean age 25.2 ± 3.35). Data were collected through a self-administered structured questionnaire, followed by an oral examination. Oral health impact profile-49 (OHIP-49) questionnaire was used to capture the individual's perceived OHRQoL. The periodontal disease assessment was based on the pocket depth (PD) and clinical attachment loss (CAL) measured with the cemento-enamel junction as the reference point. Decayed (D), Missing(M) and Filled (F) teeth (DMFT) index was used to measure the caries experience. Results The overall OHIP score for pregnant women (47.33 ± 8.56) was significantly (p = 0.03) higher, when compared to non-pregnant women (37.87 ± 9.61). Higher scores indicate a poorer OHRQoL among the pregnant women. Fourteen items of the OHIP-49 were higher for pregnant women and the subgroups that were significantly different between the two groups were: 'functional limitation', 'physical pain', 'psychological discomfort', 'psychological disability' and 'handicap'. The mean PD and CAL for pregnant women was significantly higher than that of non-pregnant women (p < 0.01). Dichotomized DMFT scores (≤6 and >6) showed significant difference (p < 0.01) between the two groups. Multivariate regression model showed that periodontitis (p = 0.01) and pregnancy status (p < 0.01) had a positive linear relationship with OHIP-49 scores after adjusting for all other variables. Conclusion The periodontal health and OHRQoL of pregnant women was poorer than non-pregnant women.

PURPOSE: To assess the prevalence of apical periodontitis (AP), as determined by orthopantomograms (OPGs), and its correlation with the quality of root fillings and coronal restorations. MATERIALS AND METHODS: This cross-sectional study evaluated a random sample of 193 patients--112 (58%) females and 81 (42%) males--who presented as new patients at the Division of Endodontics. Digital OPGs were independently examined by two reliability-calibrated endodontists. The total number of teeth present, the location of the root canalfilled teeth, and the presence or absence of AP were recorded for each radiograph. The results were statistically analysed using the chi-square test followed by model building using multiple logistic regression. RESULTS: A total of 324 endodontically treated teeth from the 193 selected radiographs were analysed. The mean number of teeth per patient was 25.5 ± 4.6, with an average of 1.64 root canal treatments per subject. Radiographically detected AP was associated with 190 (58.6%) root canal-treated teeth. The logistic model shows that the quality of endodontic treatment (adjusted odds ratio [ORa] = 1.82; 95% confidence interval [CI]: 1.40-3.17), status of coronal restoration (ORa = 1.77; 95% CI: 1.20-2.61) and the type of material used for coronal restorations (ORa = 1.39; 95% CI: 1.03-1.87) were significantly related to the periapical health of the teeth. CONCLUSIONS: The quality of endodontic treatment, status of coronal restoration and the type of coronal restorative material were found to be the most important factors influencing the health of periradicular tissue.

BACKGROUND: Oral health issues have received significant attention from most global health agencies, which have integrated these issues into their noncommunicable disease, sustainable development, and universal health coverage objectives. METHODS: This paper provides an update on the progress made in the last 2 decades and aims to highlight some of the challenges faced by the oral health care system in Kuwait. RESULTS: Despite the nation's rising expenditure on oral health care, the prevalence of oral diseases remains high in Kuwait. The lack of reliable data on periodontitis and edentulism limits the ability of researchers to comment on the trends of these conditions. This emphasises the critical need for a nationwide household-level oral health survey in both pediatric and adult populations that would provide valuable information on the oral health status of these populations. CONCLUSION: In the future, Kuwait must invest more in oral disease prevention programs, especially among children and the high-risk communities of the population.
RESUMO
OBJECTIVE: The aim of this study was to compare peri-implant clinical and radiographic status and levels of advanced glycation endproducts (AGEs) in peri-implant sulcular fluid (PISF) in waterpipe users and cigarette smokers. METHODS: Waterpipe users, cigarette smokers, and never smokers were included. Demographic details were collected using a questionnaire. Characteristics of implants (dimensions, jaw location, depth of placement, insertion torque, and duration in function) were recorded. Peri-implant modified plaque and gingival indices (mPI and mGI), probing depth (PD), and crestal bone loss (CBL) were recorded in all groups. Volume of PISF and levels of AGEs were determined using standard techniques. Sample-size estimation was done on data from a pilot investigation, and correlation between clinicoradiographic and immunoinflammatory parameters was assessed using logistic regression models. Probability values <.05 were considered statistically significant. RESULTS: In all, 25, 25, and 24 cigarette smokers, never smokers, and waterpipe users, respectively, were examined. All participants were male and had comparable mean ages. Cigarette smokers and waterpipe users had a smoking history of 20.2 ± 3.5 years and 18.8 ± 0.6 years, respectively. The mPI (P < .01), CBL (P < .01), PD (P < 0.01), and mGI (P < .01) were significantly higher in cigarette smokers and waterpipe users than never smokers. There was no significant difference in clinicoradiographic status and AGE concentrations in waterpipe users and cigarette smokers. A statistically significant correlation was recorded between AGEs and PD in cigarette smokers (P < .01) and waterpipe users (P < .01). CONCLUSIONS: Waterpipe usage is not less hazardous to peri-implant tissue health than conventional cigarette smoking. It is imperative to caution patients with dental implants about the detrimental effects of tobacco products on oral health.

This cross-sectional study intends to evaluate dentists' perceptions of COVID-19's effects on the use of emergency dental care both during and after Kuwait's lockdown periods. A convenience sample of dentists employed by the Ministry of Health's various emergency dental clinics and School Oral Health Programs (SOHP) throughout Kuwait's six governorates were invited to take part in this study. To determine the impact of various demographic and occupational characteristics on the mean perception score of the dentist, a multi-variable model was developed. The study was conducted between June-September 2021, and a total of 268 dentists (61% males and 39% females) participated in this study. When compared to pre-lockdown periods, the overall number of patients seen by dentists had significantly decreased after the lockdown period. After lockdown, there were significantly more cases of acute pulpitis with apical periodontitis, abscesses, and pericoronitis than there were before lockdown (p < 0.05). After the lockdown, a significantly higher percentage of dentists (p < 0.05) reported using fewer droplets-generating procedures to manage patients with dental emergencies. After correcting for the other variables in the model, female dentists (ß = 0.146; 95% CI = 0.071 to 1.451) and non-Kuwaiti dentist (ß = 0.012; 95% CI = 0.234 to 1.854) had a significantly (p < 0.05) more positive perception of the utilization of dental services than others after adjusting for the other variables in the model. The majority of dentists perceive that the COVID-19 pandemic has had a negative impact on Kuwait's use of emergency dental services.
RESUMO
The aim of this study was to compare radiographic and clinical status and peri-implant sulcular fluid (PISF) prostaglandin E2 (PGE2) levels among patients with and without peri-implant disease. Patients with peri-implant mucositis (PiM) (Group 1) and peri-implantitis (Group 2) and individuals without peri-implant disease (Group 3) were included. Demographic information was collected, and peri-implant modified plaque and bleeding indices (mPI and mBI), probing depth (PD), and crestal bone loss (CBL) were recorded. PISF samples were collected and PGE2 levels measured. Statistical significance was set at P < .01. A total of 22 patients with PiM, 22 with peri-implantitis, and 23 without peri-implant disease (controls) were included. Scores of mPI (P < .01), mBI (P < .01), and PD (P < .01) were higher in patients with PiM and peri-implantitis than the controls. The volumes of collected PISF were significantly higher in patients with peri-implantitis (P < .01) compared to patients with PiM and the controls. The PISF volume was significantly higher in PiM patients (P < .01) than in the controls. There was a significant correlation between peri-implant PD and PISF PGE2 levels in patients with peri-implantitis (P < .001). Raised PISF PGE2 levels indicate poor peri-implant health; therefore, PGE2 is a potential biomarker for the assessment of peri-implant health status.

PURPOSE: To synthesise and characterise nanosilver sodium fluoride (NSSF) and assess the effect of applying this formulation in vitro on artificially demineralised root dentin lesions, compared with the application of silver diamine fluoride (SDF), sodium fluoride (NAF) or no treatment, in terms of mechanical, chemical and ultrastructural properties. MATERIALS AND METHODS: NSSF was prepared using 0.5 wt% chitosan solution. On 40 extracted human molars, the buccal aspect of the cervical thirds of roots were prepared and divided into 4 groups of 10 each: control (no treatment), NSSF, SDF and NaF (n = 10). The specimens were examined using scanning electron microscopy (SEM), atomic force microscopy (AFM), and x-ray photoelectron spectroscopy (XPS). Fourier transform infrared spectroscopy (FTIR), surface and cross-sectional microhardness and nano-indentation tests were performed to determine the mineral and carbonate content, microhardness, and nanohardness, respectively. Statistical analysis was performed to determine the differences between the different treatment groups for the set parameters using parametric and non-parametric tests. Tukey's and Dunnet's T3 post-hoc tests were further used for multiple comparisons between groups (α = 0.05). RESULTS: The control group (no treatment) was found to have statistically significantly lower mean scores for surface and cross-sectional microhardness compared with all other test groups (NaF, NSSF and SDF) (p < 0.05). Spearman's rank correlation test showed statistically insignificant differences between the mineral-to-matrix ratio (M:M) and carbonate content of all groups (p < 0.05). CONCLUSIONS: Treatment of root lesions with NSSF yielded comparable results to SDF and NaF under in-vitro conditions.

PURPOSE: Cortisol levels (CL) in peri-implant sulcular fluid (PISF) samples in relation to type-2 diabetes mellitus (T2DM) and peri-implantitis remain unaddressed. It is hypothesi?sed that PISF CL are higher in patients with type-2 diabetes and peri-implantitis than in healthy patients without and with peri-implantitis. The aim was to assess the PISF CL of peri-implantitis patients without and with T2DM. MATERIALS AND METHODS: Peri-implantitis patients with T2DM (group 1), T2DM patients without peri-implantitis (group 2), non-diabetic patients with peri-implantitis (group 3) and non-diabetic patients without peri-implantitis (group 4) were included. Demographics were recorded; and patients' medical and dental records were assessed. Peri-implant modified plaque-index (mPI), modified gingival index (mGI), and probing depth (PD) and crestal bone loss (CBL) were recorded. The PISF was collected and CL were determined. p < 0.01 was considered statistically significant. RESULTS: Each of the four groups included 16 subjects (n = 64) with no difference in mean age. In groups 1 and 2, the mean duration of T2DM was 10.5 ± 0.8 and 10.6 ± 0.4 years, respectively. Mean HbA1c levels (p < 0.01) were higher and clinicoradiographic parameters (p < 0.001) were worse in group 1 than in the other groups. The median PISF volume and mean CL were higher in groups 1 (p < 0.01) and 3 (p < 0.01) than groups 2 and 4. There was a statistically significant correlation between PD and CL in group 3 (p < 0.001). CONCLUSION: Cortisol levels in the PISF are higher in T2DM and non-diabetic patients with peri-implantitis than in healthy individuals with and without peri-implantitis. Hyperglycemia did not influence peri-implant clinicoradiographic parameters and CL in the present patient population.

INTRODUCTION: Health professionals' own beliefs and practices, especially their smoking status, has been described to strongly influence their willingness to provide brief tobacco interventions (5 A's) to their patients. This study examines the association between the smoking status of faculty members in US dental programmes and (1) practice pattern; (2) perceived confidence; and (3) perceived educational preparedness of new graduates in providing the 5 A's to their patients. METHODS: This study presents data from the National Tobacco Survey of Personnel in Dental and Allied Academic Programs (TSPDAP) conducted in 2018. Faculty members in US dental/allied dental schools were invited to participate in this survey. Data were stratified based on the smoking status of the respondents as "never" and "ever" smokers (smoked <100 and ≥100 cigarettes during their lifetime, respectively). Multiple logistic regression models were used to calculate the adjusted odds ratios (aORs) and 95% confidence intervals (CIs). RESULTS: Data of 1896 participants were analysed, of whom 1032 (54.4%) were categorised as "ever" smokers. In the final regression model, low perceived barrier score was significantly associated with high practice pattern (aOR, 0.94; 95% CI, 0.92-0.97), high perceived confidence (aOR, 0.92; 95% CI, 0.90-0.95), and high perceived educational preparedness (aOR, 0.97; 95% CI, 0.94-0.98) in delivering the 5 A's to patients. Similarly, high perceived effectiveness was significantly associated with high practice pattern (aOR, 1.08; 95% CI, 1.05-1.11), high perceived confidence (aOR, 1.10; 95% CI, 1.06-1.13), and high perceived educational preparedness (aOR, 1.06; 95% CI, 1.03-1.09) in delivering the 5 A's to their patients. The smoking status of the dental personnel did not show any significant association with practice pattern, perceived confidence, or perceived educational preparedness in delivering the 5 A's to their patients. CONCLUSIONS: The smoking status of oral health care personnel was not significantly associated with their participation in tobacco cessation interventions.

AIM: Previous studies have shown that children of caregivers with low oral health literacy (OHL) had more untreated caries than children of caregivers with adequate OHL. However, there is a paucity of information on this relationship among children and youth with special health care needs (CYSHCN). Accordingly, this study aims to assess the association between the caregivers' OHL and the oral health status of CYSHCN. METHODS: This cross-sectional study was conducted in four schools dedicated for CYSHCN. A 48-item questionnaire gathered information about the demographic and socioeconomic factors, the child/adolescent's medical condition, dental characteristics, caregiver self-efficacy and the child's dental attitude. The Comprehensive Measure of Oral Health Knowledge (CMOHK) questionnaire was used to assess the caregivers' OHL. The Löe & Silness gingival index (GI) and the Silness & Löe plaque index (PI) were used to assess gingival health and plaque levels, respectively. Directed acyclic graphs (DAGs) were utilized for the selection of the appropriate set of confounding variables for regression analysis. The mean score differences and 95% confidence intervals (CI) were estimated to quantify the associations of the various covariates with oral health outcome variables. RESULTS: This study included 214 child/caregiver dyads. Most participants were physically disabled (56.1%) followed by children with hearing difficulty (9.8%) and congenital anomalies/syndromes (7.9%). The mean PI and GI of the children was 1.26±0.52 and 1.30±0.47, respectively. The median CMOHK score was 12 and the respondents were dichotomized based on the median value. Low caregiver oral health conceptual knowledge was significantly associated with higher PI scores (ß [95% CI] = -0.26 [-0.41, -0.13]; p<0.001. Older participants (12-21-year-olds) had significantly higher plaque scores compared with younger participants (6-12-year-olds) (ß [95% CI] = 0.33 [0.18, 0.51]; p<0.001). Participants who brushed their teeth twice or more daily had significantly lower (ß [95% CI] = -0.15 [-0.43, -0.01]; p = 0.046). Conceptual knowledge score was not significantly associated with GI. CONCLUSION: This study found lower caregiver OHL levels to be associated with higher plaque scores for their child.

This study longitudinally examines the relationship between the frequency of toothbrushing and the development of selected components of metabolic syndrome (MetS), along with the potential role of salivary biomarkers in this relationship. In 2014, 6317 12-year-old children underwent health examinations (T1), of which, 348 children participated in the second stage of data collection in 2019 (T2). The association between the change in the metabolic status during the 5-year follow-up examination (between T1 and T2) and frequency of toothbrushing was assessed using multinomial logistic regression analyses. At T2, healthy adolescents had significantly higher odds of toothbrushing twice or more daily compared with adolescents with components of MetS (OR = 1.99, 95% CI 1.15-3.45). Adolescents who were healthy at T1 but developed components of MetS at T2, had significantly higher frequencies of dining-out compared with adolescents with components of MetS at both T1 and T2 (OR = 0.09, 95% CI 0.02 to 0.49). Adolescents who were 'healthy' at both T1 and T2 had significantly (p < 0.05) lower levels of C-reactive protein (T2), insulin (T1 and T2), interleukin-6 (T1) and adiponectin (T1) compared with adolescents who had components of MetS. Toothbrushing and frequency of dining-out were associated with the presence of MetS components.

The coronavirus disease 2019 (COVID-19) pandemic has had a significant impact on dental education worldwide. Due to the rapid spread of COVID-19 across Kuwait, it was essential for the Faculty of Dentistry (FoD) at Kuwait University to make appropriate modifications to the functioning of the dental school. The FoD's goal was not only to ensure a safe environment for its staff, students, and patients but also to sustain the students' academic progression. The FoD adopted several measures including the establishment of a COVID-19 response team, adoption of a blended-learning model, and phase-wise re-opening of the dental center. This paper discusses on the strategies that the FoD adopted, in response to the challenges posed by the pandemic.

PURPOSE: The authors hypothesise that whole saliva soluble-urokinase-type plasminogen-activator receptor (suPAR) and tumor necrosis factor-alpha (TNF-α) levels are higher in patients with poorly-controlled than well-controlled type-2 diabetes mellitus (DM) and non-diabetic controls. The aim was to assess the periodontal clinicoradiographic status and whole-salivary suPAR and TNF-α levels in type-2 diabetic and non-diabetic individuals. MATERIALS AND METHODS: Patients with and without type-2 DM were included. In all patients, hemoglobin A1c (HbA1c) levels were measured. Participants were divided into 4 groups. Group 1: patients with poorly controlled type-2 DM; group 2: patients with well-controlled type-2 DM; group 3: non-diabetic patients with periodontitis; group 4: non-diabetic patients without periodontitis. Clinicoradiographic periodontal parameters (plaque index [PI], gingival index [GI], clinical attachment loss [AL], probing depth [PD] and mesial and distal marginal bone loss [MBL]) were measured. The whole saliva total protein concentration (TPC) and suPAR as well as TNF-α levels were measured. The level of statistical significance was set at p < 0.01. RESULTS: One hundred patients (25 patients per group) were included. Scores of PI (p < 0.01), GI (p < 0.01), clinical AL (p < 0.01), PD (p < 0.01), number of missing teeth and mesial (p < 0.01) and distal (p < 0.01) MBL were statistically significantly higher in group 1 than in groups 2-4. Scores of PI, GI, clinical AL, PD, mesial and distal MBL, and numbers of missing teeth were higher in group 3 (p < 0.01) than in groups 2 and 4. The whole saliva TPC, suPAR and TNF-α levels were statistically significantly higher among patients in group 1 (p < 0.01) than in groups 2-4. CONCLUSION: Patients with poorly-controlled type-2 DM presented with poorer clinicoradiographic periodontal status and increased whole saliva levels of suPAR, TNF-α and TPC compared with patients with well-controlled type-2 DM and non-diabetic individuals.
