Consequences of hyposalivation in relation to cancer treatment and early management of radiation-induced caries: case reports.

Given the prevalence of head and neck carcinoma and the salivary changes induced by the oral side effects of radiotherapy, such patients are at higher risk/susceptibility of developing dental caries. Radiation-caries is often under-treated in patients undergoing cervicofacial radiotherapy, yet these lesions can increase the risk of osteoradionecrosis due to necessary subsequent dental extractions. Moreover, xerostomia is accompanied by difficulties with speech, chewing and swallowing.

Manual Hair Removal for Intraoral Flaps: a Simple Practice for Professional Education and Patient Cancer Care.

After resection of malignant tumors of the head and neck, reconstructions are commonly performed using surgical free flaps. In non-irradiated patients, hair may continue to grow at the reconstruction site after surgery, causing undesirable effects such as difficult to maintain oral hygiene, food and saliva accumulation, halitosis, dysphagia, moral distress, and impact on intimacy and sexuality. Until a standardized laser therapy protocol is available, manual depilation is an option that should not be underestimated to improve the patient's quality of life and available to every oral healthcare team.

The dental microscope in endodontic education: A feasibility study of a distance learning course.

This study aimed to evaluate the feasibility of preclinical training, specifically in root canal preparation, using a virtual educational system equipped with an operating microscope. Ten postgraduate general dentistry trainees and practitioners undergoing postgraduate training in endodontics participated. The telesimulation course included three steps: theory, demonstration of practical work by the teacher and lastly practical training by the participants.

The predatory mite Pronematus ubiquitus curbs Aculops lycopersici damage under greenhouse conditions.

Background: The tomato russet mite, Aculops lycopersici, is a major worldwide pest infesting tomato crops for which only few control methods are available. At present, no commercialized beneficial organism has proven to be an effective biological control agent of the pest. As there is a strong need to develop alternatives to synthetic insecticides, we assessed the efficacy of an iolinid mite, Pronematus ubiquitus, as a preventive method against A.

Effect of Dynamically Arrested Domains on the Phase Behavior, Linear Viscoelasticity and Microstructure of Hyaluronic Acid - Chitosan Complex Coacervates.

Complex coacervates make up a class of versatile materials formed as a result of the electrostatic associations between oppositely charged polyelectrolytes. It is well-known that the viscoelastic properties of these materials can be easily altered with the ionic strength of the medium, resulting in a range of materials from free-flowing liquids to gel-like solids. However, in addition to electrostatics, several other noncovalent interactions could influence the formation of the coacervate phase depending on the chemical nature of the polymers involved.

An automated landmark method to describe geometric changes in the human mandible during growth.

Objective: The principal aim of this study was to assess an automatic landmarking approach to human mandibles based on the atlas method. The secondary aim was to identify the areas of greatest variation in the mandibles of middle-aged to older adults.

Design: Our sample consisted of 160 mandibles from computed tomography scans of 80 men and 80 women aged between 40 and 79 years.

Evaluation of Phytoseiid and Iolinid Mites for Biological Control of the Tomato Russet Mite (Acari: Eriophyidae).

Our search for a suitable biological agent to control the tomato russet mite (TRM), , was initiated in 2013. , and showed a promising pest reduction potential in a curative control strategy. Although these beneficials had a low survival on tomato and were not able to eradicate the pest, plants did not present typical TRM damage.

Root and canal morphology of the permanent teeth in medieval and current French population.

Objective: This work describes and compares the root and root canal morphology of a medieval population dating from the 8th to 10th century from the southwest of France, and a current French population.

Design: The root morphology of 579 teeth from 70 medieval individuals was analyzed using cone beam computed tomography, and compared with 690 teeth from a current French population of 329 individuals. The Vertucci classification was used to describe the root canal configuration.

Non-infectious granulomatous disorders of the upper lip: clinicopathological analysis of 11 patients.

Background: Non-infectious granulomatous disorders of the upper lip represent a special chapter of oral and maxillofacial pathology. In this work we report a case-series of this process, to analyse its main clinicopathological features and find differential data that allow us improve its diagnosis and understand its pathogenesis.

Methods: We present 11 cases of non-infectious granulomatous disorders of the upper lip, 8 women and 3 men with an age range of 29-84 years, who have been attended at the Oral Medicine Department of the IUCT (France) and the Oral Medicine Unit of the UPV/EHU (Spain).

Knowledge and Opinions of French Dental Students in Operative Dentistry - Management of Deep Carious Lesions.

Purpose: A questionnaire survey was recently undertaken among French dental students (FDSs) to investigate their practices, knowledge and opinions in various domains of minimal intervention (MI) in cariology. The present work focuses on management of deep carious lesions (DCLs).

Materials And Methods: The questionnaire was administered (Spring 2018) to all the fifth-year students of the 16 French dental schools.

Smartphone oral self-photography in teledentistry: Recommendations for the patient.

In the current context of the coronavirus disease 2019 pandemic, the deployment of telemedicine has accelerated considerably. Like telemedicine, teledentistry involves the use of telecommunication technologies to provide medical information and services. Teledentistry can contribute to remote assessment (teletriage) and continuity of care (telemonitoring).

Sexual dimorphism of the mandibular conformational changes in aging human adults: A multislice computed tomographic study by geometric morphometrics.

The aging process has an impact on mandibular bone morphology and can therefore affect shape sexual dimorphism. Understanding the effect of senescence on mandibular shape changes is particularly important to correctly estimate the sex of an individual and predict age-related conformational modifications. The purpose of this study was to assess age-related changes in mandibular shape and sexual dimorphism.
