Age related impairments in ingestion from a large population based-sample.

OBJECTIVES: Epidemiological data regarding the evolution of problems related to mastication and swallowing with age are lacking. This study aims to (i) describe changes in oral function with age, using data from a large French population, (ii) validate online, self-report uses of an ICF questionnaire in older persons, and (iii) assess whether impairment is related to avoidance of certain foods, xerostomia, body mass index (BMI) and oral health related quality of life (OHRQoL). METHODS: Volunteers aged ≥18 years with internet access completed a series of questionnaires on sociodemographic, anthropometric and oral health characteristics (oral function, Xerostomia Index (XI), OHRQoL, reasons for avoidance of certain food). Oral function was assessed using items derived from the International Classification of Functioning (ICF). Five ICF items related to ingestion function and six items related to activities and participation were used. A validation study was undertaken to identify those with poor chewing ability and low salivary flow amongst older participants reporting impairment. FINDINGS: 39 597 individuals were included. The prevalence of individuals with impairment for ICF items related to ingestion function and oral activity (eating, drinking and speaking), and the percentage of participants with poor OHRQoL increased significantly with age (p < 0.001). Each ICF item was significantly associated with OHRQoL (p < 0.001), XI (p < 0.001), BMI (p < 0.001) and avoidance of certain food due to chewing or swallowing difficulties. CONCLUSION: Overall, 21.5% and 13.5% of the study population had chewing and/or biting impairments respectively, which might affect food selection and consumption. These findings raise individual and population-based issues. Further studies are needed to assess whether impairment in oral function might increase frailty in older individuals, and also to compare data with those from other countries.

Does malocclusion affect ingestion: a systematic review.

OBJECTIVES: The multifactorial aspect of malocclusions and their consequences on ingestion function is rarely described in the literature. The aims of this review are (i) to investigate the relationship between oral ingestion and malocclusion and (ii) to gather malocclusion tools that could help screen subjects at risk of malocclusion-related ingestion disorders. MATERIAL AND METHODS: A systematic review was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocol (PRISMA-P 2015) guidelines. The analysis methods and inclusion criteria have been documented in a protocol published in the Prospective International Register of Systematic Reviews (PROSPERO) under the registration number CRD42023395840. The bibliographic search involved the PubMed®, Cochrane and PROSPERO databases. RESULTS: A total of 29 articles published between 2007 and 2023 were retained by the search criteria for the qualitative synthesis. Twenty of the studies found that the severity of malocclusion has a negative impact on oral ingestion. This review highlights that malocclusion and ingestion impairments are associated but it is not possible to determine causality due to the observational approach of many of the studies. CONCLUSION: Malocclusion has a negative impact on ingestion function. During orthodontic consultations, particular interest should be directed towards chewing, biting, and swallowing disorders, which can affect patients' nutritional status. This review offers arguments for designing further studies assessing the extent to which malocclusions may affect nutritional status. CLINICAL RELEVANCE: Orthodontic treatment should focus on improving patients' ingestion.

Oral implant rehabilitation under general anesthesia for patients with cognitive and physical disabilities: A 14-year cohort study.

STATEMENT OF PROBLEM: Oral rehabilitation with implants is an alternative to the provision of removable dentures in all patients for whom missing teeth require replacement. However, individuals with cognitive, mental health issues, and/or physical disabilities are often excluded from implant-supported prostheses because of the high perceived risk of failure linked to poor oral health, presence of parafunction, or systemic conditions. PURPOSE: The purpose of this cohort study was to describe the protocols, outcomes, and survival rates of oral rehabilitation with implant-supported prostheses in patients with cognitive and physical disabilities treated under general anesthesia (GA) in a French unit of Special Care Dentistry. MATERIAL AND METHODS: A retrospective cohort study was conducted on patient files. Data collected included demographics and information about the surgical and prosthetic phases of rehabilitation. Clinical and radiological reports were retrieved to establish the survival, success, and failure rates of implant placement according to the Health Scale for Dental Implants (HDSI) classification. RESULTS: A total of 298 dental implants had been placed under GA in 57 patients between January 2007 and August 2021. The prevalence of technical and biological postoperative complications was found to be 14% and 13% respectively. Thirty implants were determined to be failures. The estimated survival time in the population studied for loaded implants was 144.7 months [138.0; 151.3]. The cumulative survival rate was estimated to be 86% at 157 months. CONCLUSIONS: Implant-supported prostheses were found to be effective, and oral rehabilitation carried out under the conditions described was determined to be stable.

Implant-supported prostheses in patients with special needs: A systematic literature review of protocols and outcomes.

STATEMENT OF PROBLEM: Implant-supported prostheses for individuals with special needs have been considered high-risk because of the prevalence of poor oral hygiene and parafunction in this population; however, systematic evidence on protocols and outcomes is scarce. PURPOSE: The purpose of this systematic review was to summarize implant procedures and outcomes for the special needs population. MATERIAL AND METHODS: A systematic literature review was conducted using PubMed, Embase, and Scopus databases in accordance with the preferred reporting items for systematic reviews and meta-analyses (PRISMA) methodological framework. Data collected included patient information, location and number of implants, surgical and prosthetic procedures, behavior support techniques, postoperative follow-up, complications, and criteria for outcome assessment. Survival rates were pooled for quantitative analysis, and a separate analysis pooling data from groups of special needs patients that present similar risks was undertaken. RESULTS: The qualitative analysis included 79 studies involving 759 patients and 2269 implants. The quantitative analysis included 65 studies concerning 666 patients with special needs and 1886 implants. The overall weighted implant survival rate was 95.4%, with a mean follow-up duration of 40.7 ±29.5 months. CONCLUSIONS: In individuals with special needs considered suitable for implant-supported prostheses by their clinician, implant survival rates were similar to those reported in the general population.

Consensus on the terminologies and methodologies for masticatory assessment.

A large number of methodological procedures and experimental conditions are reported to describe the masticatory process. However, similar terms are sometimes employed to describe different methodologies. Standardisation of terms is essential to allow comparisons among different studies. This article was aimed to provide a consensus concerning the terms, definitions and technical methods generally reported when evaluating masticatory function objectively and subjectively. The consensus is based on the results from discussions and consultations among world-leading researchers in the related research areas. Advantages, limitations and relevance of each method are also discussed. The present consensus provides a revised framework of standardised terms to improve the consistent use of masticatory terminology and facilitate further investigations on masticatory function analysis. In addition, this article also outlines various methods used to evaluate the masticatory process and their advantages and disadvantages in order to help researchers to design their experiments.

Revisiting Orstavik's PAI score to produce a reliable and reproducible assessment of the outcomes of endodontic treatments in routine practice.

INTRODUCTION: Orstavik's periapical index is widely used for radiographic assessment of periapical status. This study analyses the reliability and reproducibility of a modified guide for the interpretation of the periapical index (PAI) scores recorded by undergraduate students. MATERIALS AND METHOD: Two groups of 4th-year students were asked to assess the PAI scores of 100 X-rays two or three times depending on the group. The reliability of their judgment was evaluated by comparing the students' assessments to those of a standard, based on the evaluations made by three teachers. Short-term stability was evaluated for two lengths of interval separating the Test and Retest phases, respectively, 1 week for Group 1 and 2 weeks for Group 2. Long-term stability was evaluated by having Group 1 repeat the Retest phase after 15 months. RESULTS: Overall mean success rates ranged from 61% to 65% according to the student group and the study phase. Intergroup comparisons showed no statistical difference. The reliability of the PAI score evaluation by students was excellent in both groups. Short-term and long-term stability were also excellent regardless of the duration of the interval between the study's phases. DISCUSSION: The image misinterpretations are discussed according to the study phases and the PAI score values. CONCLUSION: Undergraduate students can be trained to use the modified guide for scoring PAI for self-evaluation of the outcomes of the root canal treatments and re-treatments they are asked to perform during their clinical sessions.

Impairments in Food Oral Processing in Patients Treated for Tongue Cancer.

Patients surgically treated for oral cancer are affected by several underestimated deglutition disorders risk factors. This study aims to characterize the level of these food oral processing (FOP) impairments in a group of patients treated by surgery for tongue cancer. Twenty-seven consecutive patients surgically treated for tongue cancer were evaluated concerning their chewing capacity (Mastication-test), and responded to questions concerning their capacity to bite, chew and manipulate food with their tongue, and their quality of life. According to the Mastication-test, 16 patients suffered total FOP incapacities (TI group), characterized by high tumor stage, invasive carcinological surgery and necessity of reconstructive surgery; 12 patients were partially or not impaired (PI/NI-group). Tongue movement score and number of dental units were lower in the TI group than in the PI/NI-group. Subjective FOP criteria were clearly impaired in the TI group and correlated with a poor oral health-related quality of life. One year after surgery, there is a decrease in BMI for TI group patients while the PI group patients had a significant increase in BMI. All patients surgically treated for oral cancer suffered FOP impairments, but not with the same severity. Totally impaired subjects are at higher risk from long-term malnutrition. Functional evaluation of FOP should form part of the post-operative follow-up for all patients suffering from tongue cancer, using a quick combined evaluation of chewing efficiency, oral health quality of life and nutritional status.

Oral health and chemotherapy act as cofactors in malnutrition in the elderly with other cancers than head and neck malignancies.

OBJECTIVES: This study explores whether the chemotherapy regimen has a role in inducing oral health problems and malnutrition in elderly patients with other cancers than head and neck malignancies. MATERIAL AND METHODS: An observational cross-sectional study was designed to compare the relationships between oral health and nutritional status between four groups of elderly differing in cancer or chemotherapy regimen. Data were collected using a questionnaire including the Mini-Nutritional Assessment (MNA), the Geriatric Oral Health Assessment Index (GOHAI) and questions about perception of xerostomia. The oral examinations recorded the number of functional dental units (PFU) and the presence of oral lesions. RESULTS: The sample comprised 46 patients receiving chemotherapy, 48 patients on a non-chemotherapy regimen, 45 persons in complete remission not under treatment and 53 non-cancer patients. Oral health perception was significantly worse in chemotherapy patients. They reported limiting the kinds of food they consumed, the discomfort felt when eating and took medications for oral pain. Oral lesions were frequent in chemotherapy participants. Nutritional status was related to the cancer treatment regimen (OR = 4.17; p value = 0.017), the presence of oral lesions (OR = 4.51; p value = 0.003), perception of xerostomia (OR = 3.54; p value = 0.012), the number of PFU (OR = 2.51; p value = 0.046) and GOHAI score (OR = 1.617; p value = 0.019). CONCLUSION: The presence of oral lesions and the chemotherapeutic regimen were highly associated with nutritional status in older patients with cancer. CLINICAL RELEVANCE: Dental professionals should be asked to intervene preventively and per-therapy to optimise oral health status in elderly patients with other cancers than head and neck malignancies.

The "Plan" phase of a Deming cycle: Measurement of quality and outcome of root canal treatments in a university hospital.

INTRODUCTION: In many countries, dental students are taught in private or university hospitals where they treat patients under the supervision of teachers. Assessing the quality of root canal treatments (RCT) would provide information about the quality of care patients receive when treated by students. METHODS: This study describes the six-step "Plan" phase of a Plan-Do-Check-Act (PDCA) cycle that identifies and analyses clinical practices in endodontics in a university dental hospital service. RESULTS: Step 3 reported that the proportion of RCTs of adequate quality reached 57.1% and this proportion was significantly decreased when specific indicators for treatment difficulties were present. The proportion of successful RCTs after 1 year was 65.6%, and its variation was influenced by the preoperative periapical status rather than the quality of RCTs. The consensual meeting in Step 6 proposed to introduce three new procedures for the further Do, Check and Act phases of the PDCA cycle. CONCLUSION: This study encourages systematic evaluation of RCTs and provides the first step of the methodology that can be reproduced in private and hospital practices where students are asked to treat patients.

Common risk indicators for oral diseases and obesity in 12-year-olds: a South Pacific cross sectional study.

BACKGROUND: Despite the increasing need to prevent obesity and oral diseases in adolescents worldwide, few studies have investigated the link existing between these conditions and their common risk factors. This study aims to evaluate the oral health and weight status of New Caledonian Children (aged 6,9,12 years) and to identify, amongst 12-year-olds, risk indicators that may characterize the groups of children affected by oral diseases, obesity or both diseases. METHODS: This survey evaluated in 2011-2012 the oral health and stature-weight status and related risk indicators in a national representative sample of 6, 9 and 12 years-old children in New Caledonia. Dental status, chewing efficiency, height, weight and waist circumference were clinically recorded at school. The body mass index (BMI) and the waist to height ratio (WtHR) were calculated. For BMI the WHO Cut-offs were used. Twelve years-old participants responded to a questionnaire concerning socio-demographic and behavioural variables. For statistical analysis, the Clinical Oral and Global Health Index (COGHI) was developed and used. Twelve years-old children were categorised into four groups; Oral Diseases (ODG), Obesity (OG), Obesity and Oral Diseases (ODOG) and a Healthy Group (HG). A multivariate analysis was conducted using mixed-effects multinomial logistic regression models. RESULTS: Prevalence of overweight and obesity was greatly increasing from 6 years (respectively 10.8% [8.8;13.3] and 7.8% [6.0;9.9]) to 12 years (respectively 22.2% [19.9;24.7] and 20.5% [18.2;22.9]) and one third of the 12-yr-olds had an excess of abdominal adiposity. At age 12, 36.6% of the children were healthy (HG), 27.3% had oral diseases (ODG), 19.7% were obese (OG) and 16.5% had both conditions (ODOG). Geographical location, ethnicity, tooth-brushing frequency and masticatory disability were significant risk factors for the OG, ODOG and ODG groups. Ethnicity and masticatory impairment were common risk indicators for the association of oral diseases and obesity. CONCLUSIONS: In NC health promotion programs should be specifically addressed towards Native populations who are particularly exposed to oral diseases and obesity, integrating a multiple risk factors approach, in order to prevent the onset of chronic diseases in adulthood. The impact of masticatory ability on children's weight status is a major issue for future research.

Social inequalities in oral health in a group of older people in a Middle Eastern country: a cross-sectional survey.

BACKGROUND AND OBJECTIVE: The percentage of Lebanese older people has increased considerably. Given that Lebanese seniors are marginalized in the health policy-making process, we suggest a high social inequality in oral health that has not been studied so far. The purpose of our study was to describe and compare oral health status in a group of Lebanese older people according to their socioeconomic status (SES) MATERIALS AND METHODS: Participants were recruited from three different primary health care clinics in Beirut, Lebanon. Data were collected from an administered questionnaire that included sociodemographic variables, perception of oral health, and regular dental visits. Oral examination included the number of missing and decayed teeth, the prosthetic status, and the number of functional dental units (FUs). The SES of the participants was determined by educational level, previous or actual work, and neighborhood level. RESULTS: 264 participants aged 71.4 ± 6.27 years (64.7% female) were included in the study. Regular dental visit, dental status, FU, and oral health perception were significantly related to the participants' place of residence, educational level, and work. Moreover, the mean number of missing teeth (p = 0.048) and decayed teeth (p = 0.018) was significantly elevated in the low SES. CONCLUSION: There is a clear socioeconomic inequality in oral health among the Lebanese older people. Further researches should explore the potential contribution of psychosocial and behavioral factors in explaining these disparities.

Assessment of the oral health knowledge of healthcare providers in geriatric nursing homes: additional training needs required.

OBJECTIVES: This study was aimed at assessing the knowledge of oral health and training needs of health workers in geriatric nursing homes. BACKGROUND: Providing daily oral care to dependent elderly people is the best way to prevent oral disorders. Because there are no dental hygienists in France, health workers play an important role in providing oral care in nursing homes and should have correct and adequate knowledge. MATERIALS AND METHODS: Health workers from 8 geriatric nursing homes in Puy de Dôme (France) completed a 58-item questionnaire. Oral health knowledge regarding dental decay, periodontal diseases, oral hygiene and denture care was assessed. Univariate and bivariate analyses were performed. RESULTS: A total of 99 health workers took part in the study. The total mean score was significantly different if health workers had received training in oral disorders (49.3 ± 11.7 vs. 43.9 ± 10; p < 0.05) or in the maintenance of oral health (50.5 ± 10.5 vs. 42.9 ± 10; p < 0.01). The mean scores obtained in the 'dental decay' subsection and in the 'oral and denture hygiene' subsection were the lowest. CONCLUSION: Geriatric nursing home staff need training in understanding the impact of oral health on general health. Theoretical knowledge of oral diseases has to be improved in order for health workers to understand oral hygiene procedures and to help them identify early oral disorders.

Validation of the child oral health impact profile (COHIP) french questionnaire among 12 years-old children in New Caledonia.

BACKGROUND: The Child Oral Health Impact Profile (COHIP) is an Oral Health Related Quality of Life (OHRQOL) tool that assesses the impact of oral diseases on quality of life in children. This study aimed to assess the validity of the COHIP French questionnaire (45 items) and to evaluate the OHRQOL of 12-years children in New Caledonia. METHODS: After cultural adaptation of the COHIP questionnaire, data were collected from clinical oral examinations and self-administered questionnaires in a representative sample of children aged 12 years in New Caledonia. Questions related to socio-demographic status or children's perception of their oral and general health were added to the COHIP questionnaire. Studying the association between COHIP scores and health subjective perceptions or dental status indicators assessed concurrent and discriminant validity. The items of the COHIP were subjected to principal components analysis. Finally, reproducibility and reliability were evaluated using Intraclass Correlation Coefficients (ICC) and Cronbach's alpha coefficient. RESULTS: Two hundred and thirty-six children participated in the main study; mean age was 12.6 ± 0.31 years, 55.1 % were girls and diverse ethnic groups were represented. A preliminary reliability analysis has led to calculate COHIP scores with 34 items as in the English version, scores ranged from 35 to 131 (mean ± SD, 101.9 ± 16.84). Lower COHIP scores were significantly associated with the self-perception of poor general or oral health. COHIP was able to discriminate between participants according to gender, ethnic group, oral hygiene, dental attendance, dental fear and the presence of oral diseases. Test-retest reliability and scale reliability were excellent (ICC = 0.904; Cronbach's alpha coefficient = 0.880). Four components were identified from the factor analysis. CONCLUSION: The French 34-items COHIP showed excellent psychometric properties. Further testing will examine the structure and utility of the instrument in both clinical and epidemiological samples.

Bisphosphonate-related osteonecrosis of the jaw: awareness and level of knowledge of Lebanese physicians.

PURPOSE: Bisphosphonate-induced osteonecrosis of the jaw (ONJ) is a potentially destructive complication, particularly encountered in oncology. It is supposed that awareness and good knowledge of this disease by physicians are important factors of its early detection and management. This study aims to evaluate the level of knowledge among a sample of Lebanese physicians with regard to this complication. METHODS: An observational cross-sectional study was conducted at Hôtel-Dieu de France hospital between March and June 2013. Data were collected through a self-administered questionnaire distributed to 190 eligible physicians in the departments involved in prescribing bisphosphonates and managing the ONJ. RESULTS: A total of 136 valid responses were obtained (response rate 71.6 %). Eighty-six (63.2 %) physicians were treating patients with bisphosphonates: the most prescribed form being the weekly oral bisphosphonates for osteoporosis followed by zoledronate several times yearly for bone malignancies. Fifty-one (37.5 %) participants were unaware of bisphosphonate-related ONJ. Furthermore, the level of knowledge was relatively poor: the mean score of all participants was 12.42 ± 10.08, while 77 (56.6 %) had a global score more than 16 over 30. There were statistically significant associations between the level of knowledge and physicians' specialty (p value <0.0001), whether or not they prescribe bisphosphonates (p value = 0.039), the most frequently form prescribed (p value = 0.048), whether or not they attend patients already on bisphosphonate (p value = 0.047), whether or not they have observed (p value = 0.004) and treated (p value = 0.002) exposed necrotic bone of the jaw. CONCLUSIONS: Our study revealed a deficient knowledge regarding bisphosphonate-related ONJ among Lebanese physicians. Appropriate training strategies to increase their awareness are required.

A follow-up study of pulpotomies and root canal treatments performed under general anaesthesia.

OBJECTIVES: A previous study considered whether the proportions of clinically satisfactory root canal treatments (RCT) done under general anaesthesia (GA) or under local anaesthesia were equivalent, but the proportion of treatment with long-term satisfactory endodontic outcomes remains unknown. Moreover, no evaluation of pulpotomies performed under GA has been reported. MATERIALS AND METHODS: From 614 endodontic treatments (ETs) performed on permanent teeth under GA, 225 [193 RCT and 32 pulpotomies (P)] were examined after follow-up periods of 1-6 months (71 cases), 6-24 months (77 cases) and over 2 years (77 cases). Changes in the periapical index between the treatment date (T0) and the control time (T1) allowed the treatment to be classified as "success," "uncertain outcome" or "failure." Explicative variables for success of ET were the duration of follow-up and tooth-related criteria expected to affect the outcomes of endodontic treatment. RESULTS: Overall, 87 % of ETs were scored as "success," while 9 % were uncertain and 4 % were failures. There was no difference in the distribution of success in relation with the type of tooth, the pulpal status, the level of endodontic difficulty, the periapical status or the technical quality of RCT. The proportion of endodontic cases with high level of difficulties was higher in the P group than in the RCT group. CONCLUSION: Longer follow-ups and higher numbers of cases are needed to analyse the factors affecting success and failure in endodontic treatments performed under GA. CLINICAL RELEVANCE: The relatively high rates of success of pulpotomies and RCT support undertaking endodontic treatment under GA.

Measuring oral health-How can the International Classification of Functioning help?

There is a need for a theoretically informed, contextualized approach to measuring oral health from a multidisciplinary perspective that goes beyond the commonly used clinical indices and sociodental measures. This commentary aims to discuss the potential for the WHO's International Classification of Functioning, Disability and Health (ICF) to provide a model for the development of indicators for oral health. It is suggested that the ICF might provide both a theoretical model and an operational classification for indicators of oral health. The ICF model states that human experience of physical, cognitive and social functioning is universal and, thus, can be described and qualified. Human function is given social and environmental context within the model at both an individual and population level. The ICF can not only capture data regarding oral health and function at the physiological level (e.g. chewing) but also at the social level (e.g. sharing meals). It is able not only to capture aspects of preventive behaviour (e.g. caring for teeth) but also aspects of social facilitation (e.g. economic self-sufficiency) or ability to fulfil a social role (e.g. remunerative employment). It also includes aspects of social environment, such as healthcare services or political, economic and legal systems. Case studies are given as examples of the potential use of the ICF in the oral health domain. Examples are also given of the first steps that have been made towards operationalization of the ICF in data collection and oral health research. The challenges of encompassing such a comprehensive model into a practical oral health measure are discussed.

In Vitro Resistance of Natural Molars vs. Additive-Manufactured Simulators Treated with Pulpotomy and Endocrown.

Endocrowns are designed to restore endodontically treated teeth with root canal treatment (Rct). Recently, endocrowns were proposed for teeth treated with full pulpotomy (FP). No data exist on in vitro evaluations for this combination. This study aimed to evaluate the mechanical behavior of pulpotomy-treated teeth with endocrowns according to different protocols for preparation design and materials and to assess whether 3D-printed resin simulators could be a reliable alternative for human teeth during in vitro strength tests. One hundred and ten extracted natural molars were randomized into 11 groups according to the type of endodontic treatment, the material used, and the design of peripheric preparation. One hundred and ten resin simulators were separated similarly. The samples were embedded in epoxy resin blocks before being subjected to oblique compressive load until failure. For natural teeth, the variance analysis separated two homogeneous groups, one regrouping the endodontically treated or pulpotomy-treated teeth without coronal restoration and the other one regrouping all the other samples, i.e., the untreated teeth (positive controls) and the treated and restored teeth. The strength resistance was lower for the resin simulators than for natural teeth in all groups. Within the limit of this study, strength resistance is not the most important criterion for choosing the type of material, preparation, or endodontic treatment for endocrowns. Resin simulators are not efficient for in vitro strength studies.

Comparison of the OHIP-14 and GOHAI as measures of oral health among elderly in Lebanon.

BACKGROUND: The respective abilities of the GOHAI and OHIP-14 to discriminate between aged patients with different levels of oral diseases have rarely been studied in developing countries. The aim of this study was to compare the discriminative abilities of the OHIP-14 and the GOHAI in an elderly Lebanese population, and particularly to identify persons with different masticatory function. METHODS: A sample of elderly, aged 65 years or more, living independently was recruited in two primary care offices in Beirut, Lebanon. Data were collected by means of personal interview and clinical examination. The Arabic OHIP-14 and GOHAI questionnaires were used after cultural adaptation for use in Lebanon. The internal consistency, reproducibility and concurrent validity were verified. To test their discriminative abilities, the ADD (GOHAI and OHIP) and SC (GOHAI and OHIP) scores were dichotomized according to the 25th and 75th percentile respectively and logistic regressions were conducted using socio-demographic, clinical and subjective explanatory variables. RESULTS: Two hundred and six participants were included; mean age was 72 years and 60% were women. Good psychometric properties were observed for both questionnaires for internal consistency (Cronbach's alpha>0.88), reproducibility (ICC>0.86) and concurrent validity. Strong correlations were found between GOHAI and OHIP-14 scores but a high prevalence of subjects with no impact was observed using the OHIP-14. Both questionnaires were able to discriminate between participants according to age, perception of temporomandibular joint (TMJ) pain or functional status as represented by the number of dental Functional Units (FU). GOHAI was more discriminant since it identified participants with high dental care needs: high numbers of decayed teeth, low numbers of teeth and socially deprived status. CONCLUSIONS: Lebanese elderly with high dental care needs and impaired oral health were identified more easily with the GOHAI. These results may guide the choice of dental indicators to use in a national geriatric survey.

Is endodontic treatment performed under general anaesthesia technically acceptable?

OBJECTIVES: Undertaking endodontic treatment under general anaesthesia (GA) is often described as difficult and hazardous, but no study reports on safe and efficacious conditions for endodontic treatment under GA. This study aims to evaluate whether compromises made for the endodontic treatment of permanent teeth under GA are acceptable. It describes the quality of endodontic treatment undertaken in two series of consecutive patients treated either under GA or local anaesthesia (LA). MATERIALS AND METHODS: Post-operative data sheets and periapical radiographs were collected for 255 permanent teeth treated under GA during a 4-year period (GA group, 125 patients with special needs) and for 246 permanent teeth treated under local anaesthesia over 7 months (LA group, 180 healthy patients). The radiographic criteria for quality of endodontic treatment (RCQET) were considered satisfactory when (1) the root filling was within 2 mm of the apex; (2) the filling displayed no voids or defects; and (3) all the visible canals had been obturated. The type of tooth, pulpal status and periapical status were considered independent variables for RCQET. RESULTS: The proportion of satisfactory RCQET reached 63% in both groups and differed by type of tooth, being significantly lower for molars than for other teeth. CONCLUSION: From a technical point of view, compromises made for the endodontic treatment of permanent teeth under GA are acceptable. Further studies should be conducted to evaluate the long-term success of endodontic treatment performed under GA. CLINICAL RELEVANCE: This study supports the feasibility of endodontic treatment for patients treated under GA.
