AIMS: To investigate parents' ability to perceive pain experienced by their offspring with Down syndrome (DS). METHODS: Data were gathered by the use of the Oral Assessment in Down Syndrome Questionnaire in a cross-sectional survey design in France. A sample of parents of 204 children with DS and 161 of their siblings without DS was accrued. RESULTS: Parental reports of difficulty discerning if their child with DS was in pain did not change with age of the child, remaining at a prevalence of 28% to 32%. Reports of difficulty discerning where that child felt pain diminished with older age from 74% to 27%. The likelihood of parents reporting difficulty discerning if and where their child with DS had pain was greater than for a sibling without DS. However, reports of pain experience for the 2 groups were the same. Moreover, different functional and dysfunctional behavioral variables were found to be predictors of these 2 pain perception variables. CONCLUSION: Parental perception of pain is less discriminant for children with DS than for their siblings without DS. [ABSTRACT FROM AUTHOR]

Objective: Coronal pulpotomies were recently re-investigated as an alternative to root canal treatment in vital permanent teeth. General dentists may be interested in knowing how to perform full pulpotomy, in particular in face of difficult endodontic cases of vital teeth. Material and methods: A systematic review was undertaken on the PubMed and Cochrane databases in order to determine which procedure should be applied for pulp capping and coronal restoration in routine dental practice. Fifty-three publications were included and allocated to one of two methodological categories: histological and clinical studies. Results and conclusions: There is no evidence to recommend one single procedure for full pulpotomy in vital permanent teeth that can be indicated for different pulpal diagnoses which differ greatly in terms of the inflammation process from healthy teeth to irreversible pulpitis. For each clinical case, all actions aiming to prevent pre-operative contamination, to control per-operative infection and to achieve a complete seal above the radicular pulp sections are unavoidable steps that should be complied with. Reproducing procedures adopted in high quality trials could insure high success rates. [ABSTRACT FROM AUTHOR]

(p. 18) Knapp brings this argument to bear on the second part of his agenda: a "historiographical analysis of Shakespeare's dramatic authorship", examining both how Shakespeare and his society viewed his authorship and the effects of these views on Shakespeare's plays (p. 19). When Knapp analyzes the problems of the historicists' theory of collaborative dramatic authorship, this historicist strategy works very well, and generally, his arguments on this topic are well-constructed and logical. Knapp presents instances in Shakespeare's works (and others') in which Shakespeare talks about authors or authorship, or even about theater, and attempts to apply these texts to his ideas about Shakespeare as an author and about early modern authorship in general.

Oral food perception depends on somatosensory information that includes taste and can be modified by oral components and/or functions such as mastication. The purpose of this study was to describe the interplay between oral health, mastication and taste. A review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist was conducted on 615 publications found by both PubMed and backward research. Thirty-one studies have been included. The results showed that the decline in taste ability observed during the healthy ageing process could be potentiated by the deterioration of oral health and poor oral hygiene. Prosthetic treatment could modify taste ability and oral food perception. A palatal covering with removable dentures can have an impact on taste perception which may depend on taste modality. During the mastication sequence, taste is apparently scattered throughout the oral cavity, probably through saliva. The deterioration of masticatory function modifies taste perception. Oral health and oral care should consider factors influencing patients' food perception and relations between taste and mastication. Therefore, dentists may modulate these factors to improve food perception and patients' eating pleasure and quality of life. [ABSTRACT FROM AUTHOR]

The paper reviews human mastication, focusing on its age-related changes. The first part describes mastication adaptation in young healthy individuals. Adaptation to obtain a food bolus ready to be swallowed relies on variations in number of cycles, muscle strength and volume of emitted saliva. As a result, the food bolus displays granulometric and rheological properties, the values of which are maintained within the adaptive range of deglutition. The second part concerns healthy ageing. Some mastication parameters are slightly modified by age, but ageing itself does not impair mastication, as the adaptation possibilities remain operant. The third part reports on very aged subjects, who display frequent systemic or local diseases. Local and/or general diseases such as tooth loss, salivary defect, or motor impairment are then indistinguishably superimposed on the effects of very old age. The resulting impaired function increases the risk of aspiration and choking. Lastly, the consequences for eating behaviour and nutrition are evoked. [ABSTRACT FROM AUTHOR]

This article reports the second stage of a validation process. It investigates the discriminatory ability of three video indicators of mastication for a group of people with Down's syndrome, representing a target group with neurological disabilities. The variables were generated through video recordings of 11 adults with Down's syndrome and 12 healthy subjects eating four natural foods varying in hardness. The collected variables were masticatory time, number of masticatory cycles, and number of open masticatory cycles. The analytical approach attempts to test four hypotheses exploring the variations of the video indicators according to food hardness for both groups. It was demonstrated that masticatory time and the number of masticatory cycles have very strong, positive correlations and the number of open masticatory cycles has a fair, positive correlation with the food hardness rankings for both groups. Video evaluation of the test variables using real foods in people with Down's syndrome was found to be a valid means of evaluating aspects of their masticatory function. [ABSTRACT FROM AUTHOR]

In the literature, the enamelin gene ENAM has been repeatedly designated as a possible candidate for caries susceptibility. Here, we checked whether ENAM variants could increase caries susceptibility. To this aim, we sequenced coding exons and exon-intron boundaries of ENAM in 250 children with a severe caries phenotype and in 149 caries-free patients from 9 French hospital groups. In total, 23 single-nucleotide polymorphisms (SNPs) were found, but none appeared to be responsible for a direct change of ENAM function. Six SNPs had a high minor allele frequency (MAF) and 6 others were identified for the first time. Statistical and evolutionary analyses showed that none of these SNPs was associated with caries susceptibility or caries protection when studied separately and challenged with environmental factors. However, haplotype interaction analysis showed that the presence, in a same variant, of 2 exonic SNPs (rs7671281 and rs3796704; MAF 0.12 and 0.10, respectively), both changing an amino acid in the protein region encoded by exon 10 (p.I648T and p.R763Q, respectively), increased caries susceptibility 2.66-fold independent of the environmental risk factors. These findings support ENAM as a gene candidate for caries susceptibility in the studied population. [ABSTRACT FROM PUBLISHER]

Background This study aims to evaluate whether an e-learning curriculum was sufficient to impart the necessary knowledge to dentists to allow them to implement an oral health promotion intervention in an institution for persons with disability. Materials and methods Participants were asked to complete a 10-module online training course and to implement a standardised intervention in an institution. The outcome measures were as follows: online tracking of progress; multiple choice questionnaires completed at the end of most modules; self-efficacy questionnaire completed before and after online training; completion of training and calibration in the use of a standardised risk assessment form; initiation and full completion of an oral health promotion intervention in an institution; satisfaction of participants with the online training experience; and evaluation of the impact of the intervention by the institution staff. Results The study sample included 26 dentists. The 10 modules were passed by 24 dentists, and the mean value of the highest overall score recorded in the multiple questionnaires was 88.4% (±4.0). Twenty participants completed the self-efficacy questionnaire before and after training; the mean values of scores after training were statistically different and higher than those at baseline. Questionnaire regarding satisfaction with the online training experience was completed by 22 participants; all of them stated that they were satisfied with the online training experience. Conclusions The results indicate that the online training course helped participants to increase self-efficacy and to provide interventions in institutions. This study could have implications for both undergraduate and postgraduate dental education in France. [ABSTRACT FROM AUTHOR]

Persons who have multiple untreated carious lesions are at high risk of chewing difficulties and consequently an unhealthy diet, but few data are available on the impact of untreated caries on mastication in adults. This study in adults with multiple untreated caries lesions aimed to evaluate chewing deficiencies using physiological and psychosocial indicators. Forty-five patients, mean (±SD) decayed teeth 11.5 (±5.2), and 20 fully dentate caries-free subjects were observed during mastication of raw carrot and two jelly model foods differing in hardness. Criteria for chewing evaluation were carrot bolus granulometry, food refusals, chewing activity (chewing time, number of chewing cycles, chewing frequency) and oral health-related quality of life (GOHAI). Dental status was characterized by caries experience (DMFT) and posterior functional pairs of teeth. Adults with multiple untreated caries lesions suffered from chewing deficiencies, demonstrated by a decrease in food comminution related to the number of posterior functional teeth, food selection and functional alterations in oral health-related quality of life. The ability to adapt chewing activity to food hardness was preserved in this group. Further studies should be conducted to determine whether chewing function could be improved after dental treatment.

Objective: This study aimed to measure modifications of mastication after immediate loading full-arch prosthesis (ILFAP) rehabilitation. Materials and method: Fourteen patients were observed before and 6 months after ILFAP rehabilitation when masticating two natural, standardized foods (peanut and carrot) and three model foods with increasing hardness. The granulometry of the expectorated boluses from carrot and peanuts was characterized by median particle size (D50), determined at the natural point of swallowing. Chewing time (CT), number of chewing cycles (CC), and chewing frequency (CF) were video recorded. A self-assessment questionnaire for oral health-related quality of life [Geriatric Oral Health Assessment Index (GOHAI)] was also used. Results: After ILFAP rehabilitation, the mean D50 values for carrot and peanuts were smaller [Repeated Model Procedures (RMP), F = 41, p < 0.001]. Mean CT and CC values recorded with the three model foods decreased, while CF increased regardless of the model food hardness (RMP, F = 14, F = 10, and F = 11, respectively, p < 0.001). The GOHAI score increased from 43 ± 9 to 56 ± 3 ( t test, p < 0.001). Conclusion: ILFAP rehabilitation improves the ability to reduce the bolus particle size and the ability to discriminate between different food hardnesses in the 6 months post-surgery period. Clinical relevance: This study encourages the clinical development of immediate loading implantation with a fixed full-arch prosthesis protocol. [ABSTRACT FROM AUTHOR]

Genetic approaches have shown that several genes could modify caries susceptibility; AmelogeninX (AMELX) has been repeatedly designated. Here, we hypothesized that AMELX mutations resulting in discrete changes of enamel microstructure may be found in children with a severe caries phenotype. In parallel, possible AMELX mutations that could explain resistance to caries may be found in caries-free patients. In this study, coding exons of AMELX and exon-intron boundaries were sequenced in 399 individuals with extensive caries (250) or caries-free (149) individuals from nine French hospital groups. No mutation responsible for a direct change of amelogenin function was identified. Seven single-nucleotide polymorphisms (SNPs) were found, 3 presenting a high allele frequency, and 1 being detected for the first time. Three SNPs were located in coding regions, 2 of them being non-synonymous. Both evolutionary and statistical analyses showed that none of these SNPs was associated with caries susceptibility, suggesting that AMELX is not a gene candidate in our studied population.

This article presents a commentary on the practice of mastication in humans. It discusses key points emerged from a group of studies, including a need to differentiate impaired from normal mastication and the claim that the concept of masticatory efficiency is equivocal. In addition, the article outlines possible criteria of impaired mastication.

There is no established quantitative, objective method to differentiate individuals with good masticatory function from those lacking this attribute. The aim of this study was to specify a normal range of median particle size values for masticated raw carrots collected just before being swallowed. The masticatory normative indicator (MNI) value thus obtained was based on seven studies carried out by different investigators using different methods for measuring particle size in carrot boluses. A simple mathematical transformation of variables and the choice of an interval of ±1.96 times the standard deviation gave 4.0 mm as the upper limit of normal median particle size for carrots in a population of young persons with good oral health. This value identifies boluses that may be considered as resulting from impaired mastication, as illustrated in healthy individuals with experimentally hampered mastication, denture wearers, and individuals presenting with obesity or Down syndrome.

The functional and anatomical characteristics of Down's syndrome have direct repercussions on oral health; orofacial dysfunction results and feeding and swallowing are impaired. These problems have been described in an earlier article. Different techniques are proposed for the prevention of the development of orofacial dysfunction in Down's syndrome. In particular, early myofunctional therapy coupled with appliance wear has been shown to be successful over the long term when multidisciplinary management is possible. Functional or conventional orthodontic treatment may be successful for older children when performed concurrently with the use of appropriate behaviour management techniques. More recently, techniques for the compensation of masticatory dysfunction in adults have been proposed, although further research is necessary to confirm their efficacy. The aim of this second article was to review techniques for the prevention, treatment and compensation of orofacial dysfunction in persons with Down's syndrome from birth to adulthood.

The functional and anatomical characteristics of Down's syndrome have direct repercussions on oral health. Orofacial dysfunction is on account of poor neuromotor control, muscle weakness, dental anomalies, dysmorphology and intercurrent illness. In particular, feeding and swallowing are impaired. The aim of this first article was to summarize the orofacial difficulties encountered by persons with Down's syndrome at all stages of life and to explain their aetiology. Indicators are proposed for the identification of masticatory problems within this population and reduced masticatory efficiency is discussed in relation to repercussions on oral and general health and on the social integration of persons with Down's syndrome. A second article will describe techniques for preventing, treating and compensating for masticatory dysfunction in this population. [ABSTRACT FROM AUTHOR]

Purpose. This study aims to evaluate the difficulty experienced during routine hygiene and healthcare in various domains by persons with special needs attending a dental clinic compared to controls. Method. Data were gathered from 98 patients (mean age 18 SD±10.9 years) and 27 control subjects (mean age 17.3 SD±10.6 years) using a 19-item questionnaire of difficulty. Results. Seven acts showed greater difficulty in the study group: cleaning teeth (OR = 15.34; 95% CI: 3.46 - 70.10), washing ears (OR = 7.58; 95% CI: 1.70 - 33.94), dental treatment (OR = 5.54; 95% CI: 2.23 - 13.80), ear examination (OR = 3.80; 95% CI: 1.22 - 11.86), dental examination (OR = 3.06; 95% CI: 1.27 - 7.42), blood tests (OR = 2.58; 95% CI: 1.08 - 6.16) and swallowing a tablet (OR = 2.06; 95% CI: 0.01 - 0.46). Patients treated under sedation expressed significantly greater difficulty without sedation for dental examination (OR = 3.04; 95% CI: 1.21 - 7.65) and dental treatment (OR = 3.87; 95% CI: 1.54 - 9.73). Conclusions. Difficulty encountered in the acceptance of routine hygiene and healthcare could be used as an indicator for the need for Special Care facilities for outpatient treatment. Educational, behavioural and pharmacological procedures that can improve these situations are discussed. [ABSTRACT FROM AUTHOR]

AIMS: The aim of this study was to compare physiological reactivity during oral care between elderly and young subjects. MATERIALS AND METHODS: Heart rate (HR), systolic and diastolic blood pressure (SBP and DBP) and blood oxygen saturation (SPO2) were recorded seven times during two consecutive dental impression sessions in 31 complete denture wearers (aged 60.7+/-11.44 yrs) and 31 young subjects (aged 21.8+/-1.5 yrs). Subjects also reported pain and anxiety on a visual analogue scale. RESULTS: In the group of young subjects, SBP and DBP increased after the first impression and remained unchanged after the second. In the group of elderly persons, SBP and DBP increased significantly during both first and second dental impressions. Intergroup comparisons showed a longer-term relative increase in SBP and DBP in the group of elderly subjects. CONCLUSIONS: These results emphasize the need to screen cardiovascular parameters during dental care in elderly subjects. [ABSTRACT FROM AUTHOR]

Chewing efficiency may affect nutritional status in the elderly. Many elderly patients are complete denture wearers, and often present cognitive problems. Those two factors make evaluation of mastication difficult with experimental methods. Analysis of video recording may be a simple way to routinely assess chewing parameters. This study aimed at validating several parameters of video evaluation versus electromyography (EMG), which is considered the ‘gold standard’. The design was a prospective randomized study, carried out at the Faculty of Dentistry, University of Auvergne, Clermont-Ferrand, France. Twelve complete denture wearers chewed four model foods differing in hardness. Sessions were videotaped and EMG recordings were registered. Mastication time, number of masticatory cycles and cleaning time were recorded simultaneously by video and EMG. Two investigators independently analyzed the videos twice, in random order. Evaluation of criterion validity: a positive video/EMG correlation was found for the parameters ‘chewing time’ (0·89, Pearson) and ‘number of masticatory cycles’ (0·94, Spearman), whereas no statistical difference was found between these two EMG and video variables ( t-test). Inter and intra-rater reliability gave a positive intraclass coefficient (ICC) for duration of mastication (0·86–0·98), number of masticatory cycles (0·90–0·97) and cleaning time (0·90–0·98). Discriminatory ability was studied usinganova ( P = 0·01): variation was significant in masticatory duration (F = 10), number of masticatory cycles (F = 10) and cleaning time (F = 4). Video may be a useful assessment tool in prosthetic rehabilitation and can be applied to help choose the type of food (solid, semi-liquid or liquid) to administer to dependent persons, particularly those suffering from dementia.

Persons with intellectual disability have difficulty in cooperating with outpatient care, and many are referred for general anaesthesia. Intellectual disability has traditionally been a contraindication for conscious sedation. We evaluated the behavioural impact, effectiveness, and tolerance of sedation in this population using a fixed 50% nitrous oxide/oxygen mixture as a single agent. We used dental treatment as a model of outpatient care; 349 patients (192 males, 157 females; mean age 22y [SD 14]; range 3-81y) were recruited over a 12-month period at seven centres. Sedation was deemed successful if planned dental treatment was completed. Behaviour was scored with the modified Venham scale. Out of 605 sessions, 91.4% were successful. No serious adverse effects occurred. Minor adverse events (such as nausea) occurred in 10.1% of sessions. We conclude that the use of safe and effective conscious sedation may reduce the indications for general anaesthesia. [ABSTRACT FROM AUTHOR]

Down syndrome induces a neuromotor deficiency that affects the orofacial musculature, and thus could be implicated in the feeding difficulties affecting people with this disease. This study aimed to investigate the differences in chewing indicators between a group of 11 adults with Down syndrome and a group of 12 healthy subjects without Down syndrome. Chewing ability was evaluated by means of video recordings taken during a standardized meal that included 10 natural foods. The variables collected were masticatory time, number of masticatory cycles, chewing frequency, number of open masticatory cycles, and number of food refusals. There were several differences in both directions for masticatory time and number of masticatory cycles between the two groups. In addition, with the exception of purée, the group with Down syndrome had significantly lower mean chewing frequency than the reference group, and was unable to eat all the foods presented.

This study aimed at investigating the influence of teaching requirements on the clinical activity of a dental hospital.The annual clinical activity of seven classes of fifth-year students (n = 294) was monitored between 1994 and 2001 within the conservative dentistry and endodontic departments of a French dental hospital. The variables chosen were: (i) the mean number of procedures performed per student, and (ii) the proportion of different types of treatment within the global activity (i.e. endodontic treatment, anterior, and posterior restorations). These data were analysed in relation to changes in student assessment criteria over time.Quantitative clinical teaching requirements were removed for the academic year 1998—99 and student clinical activity subsequently decreased by 32.7%, going from 51.9 ± 12.2 dental procedures on average per student in 1997—98, to 29.1 ± 7.2 in 2000—01. The mean number of patients treated per student also declined significantly during this period. The size of the minimum clinical requirement altered over the years prior to being removed altogether and a positive correlation existed between the volume of activity and the minimum requirement over this time. The types of treatment provided changed independently from the assessment criteria over the study period. There was a decrease in the percentage of amalgams placed and an increase in the number of posterior composites. A negative correlation existed between the evolution of these two types of treatment.This study demonstrates that the clinical activity of a department in a dental teaching hospital is directly related to the assessment criteria fixed by the university. This may have repercussions for hospital services. [ABSTRACT FROM AUTHOR]

This article reports the second stage of a validation process. It investigates the discriminatory ability of three video indicators of mastication for a group of people with Down's syndrome, representing a target group with neurological disabilities. The variables were generated through video recordings of 11 adults with Down's syndrome and 12 healthy subjects eating four natural foods varying in hardness. The collected variables were masticatory time, number of masticatory cycles, and number of open masticatory cycles. The analytical approach attempts to test four hypotheses exploring the variations of the video indicators according to food hardness for both groups. It was demonstrated that masticatory time and the number of masticatory cycles have very strong, positive correlations and the number of open masticatory cycles has a fair, positive correlation with the food hardness rankings for both groups. Video evaluation of the test variables using real foods in people with Down's syndrome was found to be a valid means of evaluating aspects of their masticatory function. [ABSTRACT FROM AUTHOR]

Objectives: The aim of this study was to evaluate the socioeconomic status of French undergraduate dental students. Methods: A 46-item questionnaire was completed by the dental students of six universities between 1992 and 1995. Subjects related to family background, housing, schooling, income, expenditure and participation in student life were investigated. Results: A total of 1192 out of 1207 questionnaires were returned. Both genders had equal access to dental training. The average overall cost of the four last years of the dental course was 30,302 French francs and varied greatly between faculties, as did the number of hours spent at the faculty for lectures, tutorials and practicals, and clinical work. Overall, the majority of students carne from a well off social background, and had a relatively high quality of life while a small minority received no support from their families. Thirty-four per cent of students had never worked. One third of students smoked and one third regularly consumed medication of some sort. A third did not participate in any sport. Only 25% students bought dental text books and 42% of the students reported using the library regularly. Conclusions: This study offers an accurate description of the socio-economic status of French dental students that could be used as a reference for comparable studies in other European countries.

The aim of this article is to demonstrate that the presence of orofacial dyskinesia is often owing to underlying facial dysmorphology in persons with Down's syndrome. A series of cases is presented where orofacial dyskinesia was successfully treated by therapy establishing occlusal stability. The diagnosis of dyskinesia owing to dysmorphology should be precluded before any link with the degree of intellectual disability or neurological deficit is presumed. A multidisciplinary approach may be necessary to diagnose and treat these patients. [ABSTRACT FROM AUTHOR]

Background: Conscious sedation is used in dentistry to improve access and quality of care in patients who have difficulty coping with treatment. The aim of this prospective study was to describe a postgraduate training course in conscious sedation for dentists, with specific evaluation of the safe and effective administration of a 50% nitrous oxide in oxygen premix. Methods: 45 practitioners were trained between 2002 and 2004. They carried out 826 sessions of inhalation sedation in 662 patients. The clinical competency of this group was compared with an expert group. Results: There was no difference between trainees and experts in ability to complete the planned dental treatment under sedation (89.6% vs 93.2%). Trainees were less successful than experts for patients with intellectual disability (87.4% vs 94.2%, p < 0.01). For both groups, the degree of cooperation improved between initial induction and each perioperative step (Wilcoxon test, p < 0.01). However, for trainees, Venham behaviour scores varied with the type of patient (Kruskal Wallis test, p < 0.001). No major adverse effects were recorded. Trainees reported more minor adverse effects than experts (13% vs. 5.3% respectively, Fisher exact test, p < 0.001) Conclusion: The trainee practitioners provided effective and safe inhalation sedation. This challenges the current French restriction of the 50% nitrous oxide in oxygen premix to the hospital setting. Further emphasis is required on the teaching of behaviour management skills for patients with intellectual disability. [ABSTRACT FROM AUTHOR]
