The aim of this study was to determine whether self-collected pure saliva (SCPS) is comparable to nasopharyngeal (NP) swabs in the quantitative detection of SARS-CoV-2 by RT-PCR in asymptomatic, mild patients with confirmed COVID-19. Thirty-one patients aged from 18 to 85 years were included between 9 June and 11 December 2020. A SCPS sample and a NP sample were taken for each patient. Quantitative PCR was performed to detect SARS-CoV-2 viral load. Results of SCPS vs. NP samples testing were compared. Statistical analyses were performed. Viral load was significantly correlated (r = 0.72). The concordance probability was estimated at 73.3%. In symptomatic adults, SCPS performance was similar to that of NP swabs (Percent Agreement = 74.1%; p = 0.11). Thus, the salivary test based on pure oral saliva samples easily obtained by noninvasive techniques has a fair agreement with the nasopharyngeal one in asymptomatic, mild patients with a confirmed diagnosis of COVID-19.

The primary objective of this study was to evaluate the effects of sealants in preventing pit and fissure caries in primary molars. The secondary objective was to assess the sealant retention during a 2‐yr study period. A 2‐yr split‐mouth randomized clinical trial including 90 3–7‐yr‐old children was conducted in the paediatric dental department of Montpellier hospital. The dentition of each included patient was divided into an experimental side and a control side, with annual follow‐up visits. Caries increments, measured as the number of new occlusal cavitated lesions, were not different between the sealed (mean 0.23) and the control primary molars (mean 0.29). A multiple mixed‐effects logistic regression showed that male gender, moderate/high caries risk, and a higher oral hygiene index score, had a statistically significant effect resulting in higher caries increments in the primary molars, than did female gender, low caries risk, and lower oral hygiene index scores. Sealing showed no statistically significant influence on the development of new caries lesions. After 2 yr, the percentages of partially or totally lost sealants were 22.7% and 32.0%, respectively. In this sample of children, the caries increment was not significantly different between the sealed and the unsealed molars. At the end of this 2‐yr study, more than half of the sealants were totally or partially lost, which could explain the low sealant effectiveness.

Background: Despite extensive prevention programs, dental hygiene remains inadequate, particularly among children under the age of six, and early childhood caries (ECC) are still a concern. Oral hygiene behavior and preventive practices seem difficult to change at a family level. Aim. The present study aimed to better understand the reasons behind this behavior and to identify the different barriers to the implementation of adequate preventive measures. Methods: A qualitative study was conducted in the pediatric dentistry service of the Montpellier University Hospital (France) in 2019. A thematic analysis concerning three domains was performed: family environment, dental literacy, and oral hygiene. Results. The main barriers encountered by the parents were, respectively, (1) a weakness in the organization of familial life, together with a low-medium family income and a lack of authority, (2) ignorance of the necessity of treating carious primary teeth, and (3) a lack of time for brushing or supervising their children’s teeth. Conclusion: These results showed that oral hygiene and primary teeth care could not be easily achieved in the family environment of the participants, and oral health strategies should be focused not only on children but also on their parents.

Adolescence is closely associated with a high risk of caries. The identification of specific bacteria in an oral microniche, the interdental space of the molars, according to carious risk can facilitate the prediction of future caries and the anticipation of the progression or stabilization of caries in adolescents. A cross-sectional clinical study according to the bacteriological criteria of interdental healthy adolescents and carious risk factors—low and high—using a real-time polymerase chain reaction technique was conducted. The presence of 26 oral pathogens from the interdental microbiota of 50 adolescents aged 15 to 17 years were qualitatively and quantitatively analyzed. Bacteria known to be cariogenic (Bifidobacterium dentium, Lactobacillus spp., Rothia dentocariosa, Streptococcus cristatus, Streptococcus mutans, Streptococcus salivarius, Streptococcus sobrinus, and Streptococcus wiggsiae) did not present differences in abundance according to carious risk. Periodontal bacteria from the red complex are positively correlated with carious risk. However, only 3 bacteria—S. sobrinus, E corrodens and T. forsythia—presented a significant increase in the highest group. Estimating the risk of caries associated with bacterial factors in interdental sites of molars in adolescents contributes to the better definition of carious risk status, periodicity and intensity of diagnostic, prevention and restorative services.

Clinical research on herbal-based dentifrice +/− mouth rinse products is very limited compared with the plethora of research on conventional oral care products under normal oral hygiene conditions. The aim of this study was to determine the anti-inflammatory effects of a novel plant Carica papaya leaf extract (CPLE) on interdental bleeding in healthy subjects. In this randomized, single-blind parallel-design study, the eligible subjects were generally healthy non-smokers, aged 18–26, who exhibited healthy periodontal conditions upon study entry. The participants were equally randomized into the following four groups: CPLE dentifrice, CPLE dentifrice and mouthwash, sodium lauryl sulfate (SLS)-free enzyme-containing dentifrice and SLS-free enzyme-containing dentifrice with essential oil (EO) mouthwash. Subjects were instructed to brush their teeth twice a day without changing their other brushing habits. Interdental bleeding (BOIP) was measured from inclusion (T0) until the fourth week (T4) of the study. Clinical efficacy was assessed after one, two, three and four weeks of home use. The analyses compared BOIP between groups and were then restricted to participants with ≥70% and then ≥80% bleeding sites at T0. Pairwise comparisons between groups were performed at T0 and T4, and a logistic regression identified correlates of gingival bleeding (T4). Among 100 subjects (2273 interdental sites), the median percentage of bleeding sites per participant at T0 was 65%. The bleeding sites dramatically decreased in all groups between T0 and T4 (relative variations from −54% to −75%, p < 0.01 for all). Gingival bleeding did not significantly differ between the CPLE dentifrice and the SLS-free dentifrice +/− EO mouthwash groups (from p = 0.05 to p = 0.86), regardless of the baseline risk level. Among the CPLE dentifrice users, fewer bleeding sites were observed when toothpaste and mouthwash were combined compared to bleeding sites in those who used toothpaste alone (21% vs. 32%, p = 0.04). CPLE dentifrice/mouthwash provides an efficacious and natural alternative to SLS-free dentifrice +/−EO-containing mouthwash when used as an adjunct to mechanical oral care to reduce interdental gingival inflammation.

Effective sterilization of reusable instruments contaminated by Creutzfeldt–Jakob disease in dental care is a crucial issue for public health. The present cross-sectional study investigated how the recommended procedures for sterilization were implemented by French dental practices in real-world settings. A sample of dental practices was selected in the French Rhône-Alpes region. Data were collected by a self-questionnaire in 2016. Sterilization procedures (n = 33) were classified into 4 groups: (1) Pre-sterilization cleaning of reusable instruments; (2) Biological verification of sterilization cycles—Monitoring steam sterilization procedures; (3) Autoclave performance and practitioner knowledge of autoclave use; (4) Monitoring and documentation of sterilization procedures—Tracking and tracing the instrumentation. Answers were provided per procedure, along with the global implementation of procedures within a group (over 80% correctly performed). Then it was verified how adherence to procedure groups varied with the size of the dental practice and the proportion of dental assistants within the team. Among the 179 questionnaires available for the analyses, adherence to the recommended procedures of sterilization noticeably varied between practices, from 20.7% to 82.6%. The median percentages of procedures correctly implemented per practice were 58.1%, 50.9%, 69.2% and 58.2%, in Groups 1, 2, 3 and 4, respectively (corresponding percentages for performing over 80% of the procedures in the group: 23.4%, 6.6%, 46.6% and 38.6%). Dental practices ≥ 3 dental units performed significantly better (>80%) procedures of Groups 2 and 4 (p = 0.01 and p = 0.002, respectively), while no other significant associations emerged. As a rule, practices complied poorly with the recommended procedures, despite partially improved results in bigger practices. Specific training regarding sterilization procedures and a better understanding of the reasons leading to their non-compliance are needed.

The objective of the present study was to analyze the clinical outcomes of 447 monoblock ceramic chairside computer-aided design/computer-aided manufacture (CAD/CAM) reconstructions over a 7-year functional period. Of these reconstructions, 212 were peripheral crowns and 235 were endocrowns. The restorations were placed between 2003 and 2008 in a total of 323 patients. They were created using a chairside CAD/CAM method and the same materials in all cases. All of the crowns were manufactured and glued during the same clinical session by the same practitioner. Data were descriptively analyzed and survival probabilities were calculated using Kaplan-Meier statistics. Of the 447 restorations, only 6 failures occurred, resulting in a success rate of 98.66%. All of the failures were the result of a partial ceramic fracture. Of the six ceramic fractures, five appeared on peripheral crowns and one on an endocrown. All fractures appeared in the first 24 months, including two in the first month. Log-rank test comparing incidence rates between crowns and endocrowns showed no significant differences (P = .08). This survival rate study reinforced the use of CAD/CAM full ceramic crowns and endocrowns on molars, showing a much more favorable survival rate for endocrowns.

Purpose In France, all incarcerated prisoners are required to undergo a dental examination (Ministère de la santé et de la protection sociale, 2004 and Ministère de la justice, 2004). However, only one in two prisoners benefits from this oral health check-up. Oral teleconsultation could improve the quality of oral care in prisons. The paper aims to discuss these issues. Design/methodology/approach The focus of this study was therefore to apply oral teleconsultation as an experiment. Using an oral teleconsultation system, a dentist and a nurse were separately asked to give patients a score, according to how urgently their dental issue needed to be treated. This score will henceforth be referred to as the “dental emergency scores given”. Findings The separate dental emergency scores given by the dentist and the nurse were compared and the results demonstrate the following: – 36.7 per cent (11) of the two scores were equal – 53.3 per cent (16) of the two scores differed by 1 point – 10 per cent (3) of the two scores differed by 2 points. The average score of the nurse was 2.23 and that of the dentist was 2.13. The small disparity should not obscure the fact that 63 per cent of the diagnoses turned out to be incorrect. Practical implications Dental care could easily be improved with oral teleconsultation as a care plan could be developed for each patient. Social implications The condition of one’s dental health is, of course, very important for general health, but it also affects social aspects. Good oral hygiene and health are very important when looking for a job after having been released from prison. Originality/value This is the first study on oral teleconsultation in prisons. Dental care is rarely studied on prisoners. Telemedicine in dentistry is just beginning all over the world. This study is the first step of an extensive project in the University Hospital of Montpellier and the Villeneuve-les-Maguelone prison.

The aim of this study, applied in the field of periodontal diseases, was first to analyze the fatty acid levels in two groups of patients and then to propose a method for selecting the most relevant predictors. Two groups of patients, 29 with moderate or severe periodontitis and 27 who served as controls, were clinically examined, and their fatty acids in serum were measured by gas chromatography. The levels of these 12 fatty acids were the variables of the analysis. Logistic regression, together with the area under the receiver operating characteristic (ROC) curves, allowed determining a composite score which led to a subset of the most relevant covariables. The fatty acid levels differed significantly between the 2 groups in multivariate analysis (P=0.03) and the best logistic model was obtained with only 3 predictive variables: arachidonic acid, linoleic acid, and DHA. Fatty acid levels in serum of patients were significantly different according to the presence of moderate or severe periodontitis. By taking into account the comparison of ROC curves, our approach could optimize the choice of variables in multivariate analyses and could better fit it with diagnosis and prognosis of oral diseases in dental research.

Gap at the implant-healing abutment junction can increase the risk of bacterial proliferation. In this study, we determined the leakage at the microgap, and we evaluated hand screwing among clinicians.The torques tested with nitrogen gas flow were 10, 15, 20, and 30 N cm, and 54 clinicians were asked to torque down a healing abutment as for a surgical procedure.There were no significant differences between 10 and 15 N cm, with a total lack of tightness. For 20 and 30 N cm, there was a notable decrease in leakage. The torque achieved by hand was There was a significant difference related to the strength of tightening. Under the conditions of our experiment, the gap of connection was reduced with a torque of ≥20 N cm. Only a small portion of the clinicians could obtain these values by hand. Therefore, a dynamometrical manual wrench should be used to minimize the gap during the osseointegration period.

Although the bond strength of self-adhesive bonding agents is inferior to that of other families of adhesives, it is still adequate for orthodontic purposes provided prior enamel etching is performed. To determine the efficacy of RelyX™ Unicem® (3M) self-adhesive cement both in vitro and in vivo and to compare it with the combination of MIP® (3M), a moisture-insensitive primer, with a traditional hydrophobic adhesive, Transbond Supreme Low Viscosity® (3M). Comparison of bonding results on 23 trial dentures using RelyX™ Unicem® (3M) with bonding results on 29 trial dentures using a combination of MIP® and Transbond Supreme Low Viscosity® (3M), by means of a multipurpose Instron® 4444 testing machine. Results: the breaking force of MIP®/Transbond Supreme Low Viscosity® (3M) (mean: 144 ± 37.5 Newtons) was significantly higher than that of RelyX™ Unicem® (3M) (mean = 110 ± 26 Newtons) (P = 0.001). A 12-month prospective, randomized, monocentric, single-blind clinical study in order to investigate the failure rate of orthodontic attachments according to the type of adhesive used, and the precise site of the debonding. Bracket bonding was performed on 16 patients with randomized allocation of the two adhesives to each of the semi-arches. Results: The failure rates were: 15.3% for the MIP®/Transbond Supreme Low Viscosity® (3M) combination and 8.2% for the RelyX™ Unicem® (3M), with a significant difference (P = 0.039). The more posterior the bonded teeth, the greater the superiority of RelyX™ Unicem® (3M). The in vivo results did not concord with those obtained in vitro. RelyX™ Unicem® (3M) exhibited lower adhesion values in vitro and yet it presented a debonding rate almost half that of the MIP®/Transbond Supreme Low Viscosity® (3M). The viscosity of RelyX™ Unicem® (3M) and its moisture tolerance would appear to account for these results. With prior etching, RelyX™ Unicem® (3M), a self-adhesive, self-etching bonding agent is compatible with use in the orthodontic indirect bonding technique. The MIP®/Transbond Supreme Low Viscosity® (3M) combination, though very effective, still remains sensitive and requires special care during usage.

Connaître l’efficacité de la colle auto-adhésive RelyX™ Unicem® (3M), à la fois in vitro et in vivo, et la comparer à l’association d’un adhésif hydrophile, le MIP® (3M), et d’une colle traditionnelle hydrophobe, le Transbond Supreme Low Viscosity® (3M). Comparaison du collage de 23 maquettes au RelyX™ Unicem® (3M) au collage de 29 maquettes à l’association MIP®/Transbond Supreme Low Viscosity® (3M), à l’aide d’une machine à essai universelle Instron® 4444. Résultats : la force de rupture du MIP®/Transbond Supreme Low Viscosity® (3M) (moyenne = 144 ± 37,5 Newton) était significativement supérieure à celle du RelyX™ Unicem® (3M) (moyenne = 110 ± 26 Newton) (p = 0,001). Étude clinique prospective sur 12 mois, randomisée, monocentrique, en simple insu, afin d’étudier le taux de décollements des attaches orthodontiques selon le type de colle utilisée, et la localisation du décollement ; le collage des attaches a été effectué sur 16 patients, avec un tirage au sort des deux colles pour la répartition par hémi-arcade. Résultats : les taux d’échecs étaient de 15,3 % pour l’association MIP®/Transbond Supreme Low Viscosity® (3M) et de 8,2 % pour le RelyX™ Unicem® (3M), avec une différence significative (p = 0,039). Plus les dents concernées par le collage étaient postérieures, plus la supériorité du collage au RelyX™ Unicem® (3M) était grande. Les résultats obtenus in vivo n’ont pas été conformes à ceux obtenus in vitro. Le RelyX™ Unicem® (3M) présentait des valeurs d’adhérence inférieures in vitro et pourtant, il présentait un taux de décollements quasi deux fois inférieur à celui du MIP®/Transbond Supreme Low Viscosity® (3M). La viscosité du RelyX™ Unicem® (3M) et sa tolérance à l’humidité semblent pouvoir expliquer ces résultats. Le RelyX™ Unicem® (3M), colle automordançante et auto-adhésive, avec mordançage préalable, est compatible avec une utilisation en orthodontie en technique de collage indirect ; l’association MIP®/Transbond Supreme Low Viscosity® (3M) aussi performante soit-elle, reste sensible et exigeante quant à son protocole d’utilisation.

To evaluate the prevalence of palatine tonsilloliths. 150 consecutive CT examinations (75 males and 75 females) were read. Tonsilloliths were found in 37 patients (24.6%; confidence interval 17.7-31.6%), of which 18 (48%) had a bilateral location. No influence of sex or age was observed (p = 0.37 and p = 0.57, respectively). 26 patients (70%) had more than 1 concretion. The largest tonsillolith was 7 mm. None of the tonsilloliths found were involved in the reason for prescribing the CT. The radiographic density of the tonsilloliths was between 216 and 2959 HU. Palatine tonsilloliths could affect approximately one-quarter of the population. This prevalence is likely to be underestimated in daily clinical practice because small concretions do not result in any functional impairment and are not visible on orthopantomographs.

In clinical situations carious dentine tissues can be discriminated by most caries fluorescence detection tools, including a new fluorescence intra‐oral camera. The objectives of this study were: (i) to analyze the Raman spectra of sound, carious, and demineralized dentine, (ii) to compare this spectral analysis with the fluorescence variation observed when using a fluorescence camera, and (iii) to evaluate the involvement of the Maillard reaction in the fluorescence variations. The first positive hypothesis tested was that the fluorescence of carious dentine obtained using a fluorescence camera and the Raman spectra variation were closely related. The second was that the variation of fluorescence could be linked with the Maillard reaction. Sound dentine, sound dentine demineralized in aqueous nitric acid solution, carious soft dentine, sound dentine demineralized in lactic acid solution, sound dentine demineralized in aqueous nitric acid solution and immersed in methylglycoxal solution, and sound dentine demineralized in aqueous nitric acid solution and immersed in methylglycoxal and glucose solutions, were studied using micro‐Raman spectroscopy. Modifications in the band ratio of amide, phosphate, and carbonate were observed in the decayed and demineralized groups compared with the sound dentine group. The results indicate that a close relationship exists between the Maillard reaction and fluorescence variation.

Dietary fluoride supplements were first introduced to provide systemic fluoride in areas where water fluoridation is not available. Since 1990, the use of fluoride supplements in caries prevention has been re‐evaluated in several countries. To evaluate the efficacy of fluoride supplements for preventing dental caries in children. We searched the Cochrane Oral Health Group's Trials Register (to 12 October 2011), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 3), MEDLINE via Ovid (1950 to 12 October 2011), EMBASE via Ovid (1980 to 12 October 2011), WHOLIS/PAHO/MEDCARIB/LILACS/BBO via BIREME (1982 to 12 October 2011), and Current Controlled Trials (to 12 October 2011). We handsearched reference lists of articles and contacted selected authors. We included randomised or quasi‐randomised controlled trials comparing, with minimum follow‐up of 2 years, fluoride supplements (tablets, drops, lozenges) with no fluoride supplement or with other preventive measures such as topical fluorides in children less than 16 years of age at the start. The main outcome was caries increment measured by the change in decayed, missing and filled tooth surfaces (DMFS). Two review authors, independently and in duplicate, assessed the eligibility of studies for inclusion, and carried out risk of bias assessment and data extraction. In the event of disagreement, we sought consensus and consulted a third review author. We contacted trial authors for missing information. We used the prevented fraction (PF) as a metric for evaluating the efficacy of the intervention. The PF is defined as the mean caries increment in controls minus mean caries increment in the treated group divided by mean caries increment in controls. We conducted random‐effects meta‐analyses when data could be pooled. We assessed heterogeneity in the results of the studies by examining forest plots and by using formal tests for homogeneity. We recorded adverse effects (fluorosis) when the studies provided relevant data. We included 11 studies in the review involving 7196 children. In permanent teeth, when fluoride supplements were compared with no fluoride supplement (three studies), the use of fluoride supplements was associated with a 24% (95% confidence interval (CI) 16 to 33%) reduction in decayed, missing and filled surfaces (D(M)FS). The effect of fluoride supplements was unclear on deciduous or primary teeth. In one study, no caries‐inhibiting effect was observed on deciduous teeth while in another study, the use of fluoride supplements was associated with a substantial reduction in caries increment. When fluoride supplements were compared with topical fluorides or with other preventive measures, there was no differential effect on permanent or deciduous teeth. The review found limited information on the adverse effects associated with the use of fluoride supplements. This review suggests that the use of fluoride supplements is associated...
