EFFECT OF IMPRESSION TECHNIQUES ON SOFT TISSUE VERTICAL DISPLACEMENT IN REMOVABLE PARTIAL DENTURE. A PILOT STUDY

Abstract Purpose: The purpose of this study was to evaluate the vertical displacement of soft tissue during different impression procedures using various spacing of the custom tray, and to determine which impression technique would allow the minimal movement. Material and Methods: 21 partially edentulous subjects were selected and enrolled in the study. Each one of them was subjected to four different impression procedures: three alginate impressions with different spacing of the custom tray and one composed with different impression materials, then casts were constructed. Light-curing acrylic occlusal platform was constructed on the primary model and perforated in 10 different points. The plate was positioned on each of the 4 plaster models, then in the mouth; and the distance between the plate and the top of the crest was measured. Each measurement was repeated three times and the mean was recorded. Repeated measures analyses of variance followed by Bonferroni multiple comparisons were conducted to explore the difference among the groups. The alpha error was set at 0.05. Results: The mean measurement of the distance between the plate and the top of the crest was significantly different among groups (-p-valu

Cross-cultural adaptation and psychometric properties of an Arabic language version of the Brief Illness Perception Questionnaire in Lebanon

Background: Patients’ positive illness perceptions (IPs) significantly contribute to treatment success. The Brief Illness Perception Questionnaire (Brief IPQ) is widely used in various diseases for assessing IPs. It was developed in English-speaking countries and studies on it in Arab countries are scarce.Objectives, Setting and design: This observational cross-sectional study aimed to cross-culturally adapt the Brief IPQ English version into a modern Arabic language version and determine its psychometric properties in a sample of Lebanese cardiac disease patients. This study was approved by the Institutional Review Board of Saint Joseph University of Beirut, Lebanon.Participants: A convenience sample of 30 patients with cardiac disease were recruited during routine visits to cardiologists’ offices in Beirut, Lebanon. Inclusion criteria were at least one cardiac disease for at least 6 months with no acute episode or exacerbation of the disease during the 6 preceding months, age]18 years, and the ability to read and comprehend Arabic. The pre-final version of the Brief IPQ Arabic version was tested for face and content validity. The meaning, comprehensibility, and acceptability were studied by individual interviews. For discriminant validity and internal consistency of the Brief IPQ Arabic version (Brief IPQ-Ar), 100 patients were recruited in a similar manner using the same inclusion criteria. To assess reproducibility, 30 patients, selected randomly from the 100 patients, filled the questionnaire a second time, 34 weeks after its first administration and under the same conditions.Main outcome measures: Psychometric properties of the Brief IPQ-Ar among Lebanese patients suffering from cardiac diseases.Results: Semantic equivalence between the Brief IPQ-Ar questions and patients’ descriptions was 100%. Cronbach’s alpha was 0.717, which shows good internal consistency. Reproducibility was satisfactory (ICC values > 0.776). Moreover, the Brief IPQ-Ar discriminated participants according to the type of cardiac disease and treatment-related characteristics.Conclusions: We confirmthat the Brief IPQ-Ar is appropriate for exploring IPs in cardiac disease patientswhose first language is Arabic. Further research should be conducted to test this Arabic version in other types of diseases.Keywords: adaptation; Arabic; Brief IPQ; cardiology; cross-cultural; psychometri

Adaptation et validation transculturelle d’un questionnaire de qualité de vie liée à la santé orale des sujets complètement édentés au Liban

The objectives of the present study were to adapt and validate transculturally the Arabic version of the OHIP-EDENT in a group of completely edentulous Lebanese individuals aged 60 or over. A sample of edentulous subjects aged 60 and over was recruited from the Department of Removable Prosthodontics, at the Saint-Joseph Unoversity of Beirut, and from a private medical clinic in Beirut. The Arabic version of OHIP-EDENT was applied. It comprised 19 items grouped into seven dimensions:functional limitation, pain, psychological discomfort, physical incapacity, psychological incapacity, social incapacity and handicap. Reproducibility, internal consistency, concurrent validity and discriminant validity were assessed. Two hundred and two participants were included in the study. The average age was 72.94 ± 7.378 years and 51% were women. The OHIP-EDENT presented good reproducibility (Intra-class correlation coefficient equal to 0.922), good internal consistency (Cronbach’s Alpha coefficient equal to 0.929) and good concurrent validity. OHIP-EDENT was significantly associated with using functional prostheses, prosthetic status, stability of the prostheses and the number of years the prostheses were worn (p \u3c0.05).The Lebanese version of OHIP-EDENT has shown good psychometric properties. The properties of OHIP-EDENT should be compared with other OHRQoL tools according to cross-sectional and prospective studies to confirm the results obtained

ORAL HEALTH OF COMPLETELY EDENTULOUS PATIENTS DURING THE COVID-19 PANDEMIC AND ITS IMPACT ON THEIR NUTRITIONAL STATUS: A PILOT STUDY

The COVID-19 pandemic, declared by the WHO on May 2020, has forced governments around the world to adapt several restrictive measures causing difficulties of access to oral healthcare. In Lebanon, a lack of data on these difficulties and their consequences for completely edentulous people prompted the realization of a pilot study evaluating the impact of this pandemic on access to oral healthcare and on the oral health status, oral health-related quality of life (OHRQoL), and nutritional status of these individuals. The study was conducted at the Removable Prosthodontics Department of the Faculty of Dentistry at Saint-Joseph University of Beirut through a personal interview including the use of the Lebanese version of the Oral Health Impact Profile for Edentulous Patients (OHIP-EDENT) and the Arabic versions of the Activity of Daily Living index (ADL), and the Mini Nutritional Assessment index (MNA) questionnaires, followed by a clinical examination. Data collection from 17 completely edentulous subjects showed high difficulty in accessing oral healthcare and negative repercussions on their oral health, OHRQoL and nutrition

Détermination de l’âge dentaire en odontologie médico-légale

The study of the dentition is a common manner for age determination. In this article, we will discuss the pertinent methods to estimate the dental age of unknown dead or young alive people. In children, histological techniques as well as tooth eruption or calcification are appropriate to assess dental age in postmortem. After 15 years, it becomes difficult to estimate the age, since the phenomena related to the tooth eruption or calcification is completed. Therefore, the rate of racemization and Lamendin method are pertinent to determine the age adults in postmortem. Finally, in young alive people where age determination has legal interest, the mineralization of the wisdom tooth is a fundamental criterion for evaluating dental age. The determination of age depends on physiologic, environmental, genetic and pathologic factor. Thus, the age estimation in Lebanese population might be appraised using the methods universally adopted after adjustment, to obtain an accurate evaluation

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

Abstract 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.</p
