Age estimation from alveolar bone loss, re-evaluation of Ruquet's method.

There are many dental age estimation methods, but all the methods do not correspond, especially for aging methods for adults and mature individuals, to the reality of the forensic field, which favors simple, effective, and easy-to-use methods. Ruquet (2015) developed a method based on alveolar bone loss that predicts age for individuals between 25 and 60 years old and is even more accurate for those 25-40 years old. This study re-evaluated Ruquet's alveolar bone loss method using three-dimensional imaging of individuals whose age and sex were known, without taking into account their medical conditions.

Conformational variations of the medial epicondyle of the humerus: A case study of fusion anomaly on dry bones.

The estimation of a biological profile in biological anthropology is a central point in the study of human remains. To specify this profile, the observation of variations, and pathologies on the skeleton is a tool that makes an individual unique. In this research, the focus was on the distal part of the humerus.

Concordances and correlations between chronological, dental and bone ages: A retrospective study in French individuals.

Bone and dental maturations are subject to physiological, environmental and pathological variables and are unique to each individual. Numerous methods for age estimation appeared to answer a new demand explained by the contemporary migratory movements and the increase of the crime rates. The objective of this study was to observe the relationships between skeletal and dental maturation stages to estimate which methods can be applied to a French population.

Early Neurological Assessment and Long-Term Neuromotor Outcomes in Late Preterm Infants: A Critical Review.

: Late preterm (LP) infants (born between 34 and 36 weeks of gestational age) are considered at higher risk of neonatal morbidities, mortality, and neurological impairments than full-term born infants (FT). The aim of this study was to provide a critical review of the literature outlining the different aspects of neurological function reported both in the neonatal period and in the follow up of late preterm infants. : A comprehensive search of the MEDLINE, Embase, PsycINFO, and CINAHL electronic databases was made, using the following search terms: 'Late preterm infants', 'Near term infants', 'neurological assessment', 'neurological outcome', 'neuromotor outcome', cerebral palsy', 'CP', 'motor impairment', including all the studies reporting clinical neurological assessment of LP (including both neonatal period and subsequent ages).

Educational outcomes of a new curriculum on interproximal oral prophylaxis for dental students.

Objective: The aim of this study was to evaluate the effectiveness of a preclinical oral prophylaxis education program by examining the effectiveness of the teaching module on changes to the students' attitudes towards their individual hygiene behaviors with interdental brushes (IDBs).

Methods: As being part of a new didactic program on oral interproximal prophylaxis, all preclinical third-year students (n = 96) enrolled in the 2014/15 academic year received theoretical, preclinical, and clinical lessons on interproximal prophylaxis. The evaluation of educational outcomes was linked to observed changes in students' hygiene behaviors using interdental brushes.

Estimation of Age Using Alveolar Bone Loss: Forensic and Anthropological Applications.

The objective of this study was to utilize a new odontological methodological approach based on radiographic for age estimation. The study was comprised of 397 participants aged between 9 and 87 years. A clinical examination and a radiographic assessment of alveolar bone loss were performed.

Optimal placement of the two anterior implants for the mandibular All-on-4 concept.

The novelty of the All-on-4 concept for a mandibular implant-supported fixed dental prosthesis is the inclination of the posterior implants. Typically, the anterior implants are placed lingually relative to the canine/incisor teeth and perpendicular relative to the occlusal plane. According to the laws of elementary biomechanics, the long axis of the implant unit should be aligned to the axis of the occlusal loading forces during clenching in the maximal intercuspal position.

Age determination of adult individuals by three-dimensional modelling of canines.

Accurate age determination is fundamental in both forensic medicine and anthropology. Many methods that relate dental characteristics to adult age have been proposed, but there is still no simple and reliable method that does not damage the study material. The aim of this work was to propose a relevant and practical technique for determining age in adults that could be used in both living and deceased individuals.

Odontological approach to sexual dimorphism in southeastern France.

The aim of this study was to establish a prediction formula to allow for the determination of sex among the southeastern French population using dental measurements. The sample consisted of 105 individuals (57 males and 48 females, aged between 18 and 25 years). Dental measurements were calculated using Euclidean distances, in three-dimensional space, from point coordinates obtained by a Microscribe.

Three-dimensional modeling of the various volumes of canines to determine age and sex: a preliminary study.

Canines are usually used in anthropological and forensic sciences for sex and age determination. The best methods to estimate age are based on secondary dentine apposition, evaluated from periapical X-rays. The aim of this study was to propose a new method of sex and age estimation using 3D models to obtain more precise predictions using tooth volumes.

Estimation of gestational age from tooth germs: Biometric study of DentaScan images.

The few available studies on fetal age estimation concern very small samples, and statistical analysis is sometimes inadequate. In this survey, we used germs of deciduous teeth to estimate fetal age. Forty-nine fetuses and 40 mandibles were scanned, and observations and measurements were made on DentaScan images.

Characteristics and prediction of the alveolar bone loss: essay of modeling.

The alveolar bone loss is a phenomenon which intervenes throughout the life and which can be aggravated by the action of individual and behavioural factors. From this observation we shall try to characterize it and to propose formulas of prediction of the alveolar bone loss according to the age of the patient. We shall expose an analysis of factors bound to the alveolar bone loss and propose a modeling of the alveolar bone loss according to the age in an essentially predictive purpose.

Assessment of oral status and oro-pharyngeal candidosis in elderly in short-term hospital care.

Objectives: To evaluate prevalence of oral candidosis and predisposing conditions in hospitalized elderly patients.

Design: We examined 104 elder patients recently hospitalized in two geriatric hospitals for shortterm hospital care.

Methods: Information was collected on patients' sex, age, mental and physical disabilities, smoking habits, medical prescriptions, oral pathologies, denture wearing, oral hygiene habits and oral hygiene level.

Gingival contour assessment: clinical parameters useful for esthetic diagnosis and treatment.

Background: The purposes of this study were to quantify some clinical parameters that are useful as esthetic guidelines when the gingival contour is modified and to compare the left and right sides of the six maxillary anterior teeth.

Methods: Maxillary casts mounted on an articulator according to the axis orbital plane were photographed from 103 young adults. The angle formed between the gingival line and the maxillary midline (GLA) and the distance between the gingival zenith of the lateral incisor and the gingival line (LID) were measured.

Validation of biometric study of fetal mandibles by 3D tomodensitometric images.

We carried out a biometric study of the mandible during the last two trimesters of fetal life using three-dimensional tomodensitometric images. We first validated the method of fetal mandible measurement from three-dimensional reconstructions, and then compared these measurements with direct measurements on dissected mandibles. Thanks to the biometric technique on three-dimensional images, dissection of mandibles is no longer necessary, allowing the material to be conserved for later studies.

[Probabilistic approach to age estimation of children by dental maturation].

Two probabilist methods of age prediction in children are proposed: they are both based on the radiological presence of erupted teeth or germs. Using an apprenticeship sample of known age and sex, we established several discriminant models (+/- 13, +/- 16, +/- 18 years old). We also evaluated a Bayesian model with the following age groups: < 13, [13-16[, [16-18[, > or = 18 years old, or [X and Y] years old.

New forensic approach to age determination in children based on tooth eruption.

The present study proposes equations for age determination both in living and dead children, obtained with the help of stepwise ascending multiple linear regression. The equations should be applied, based on the number of erupted teeth and tooth germs, which were detected on radiographs, during clinical examination and in infant skeletal remains. The proposed equations proved to be efficient just like Demirjian's method used as a reference today, and permit age estimation till 20 years of age.

[Determining factors in the wearing of a removable prosthesis: the role of familial example. Prosthetic risk: the influence of parental behavior].

The aim of the present study was to provide a fuller clarification of the influence of sociocultural and socioeconomic data on the bucco-dental ageing. In Particular, was suspected, the influence of the parental behavior towards the wearing of their own prostheses in the wearing of removable prostheses among the descendants. The study was led in a dental service (CHU of Marseille) on 260 from 50 to 70 years old persons.

Limits of the Lamendin method in age determination.

This study shows that epithelial attachment level, used as age determination criterion in Lamendin's method, is not reliable for adults of either sex above the age of 49 years with periodontal diseases in any quadrant. The underestimation of calculated age increases from 7 to 19 years with chronological age. On the other hand, the present paper confirms the pertinence of dentin translucency as an age indicator in Lamendin's method.
