Noninvasive Total Cholesterol Level Measurement Using an E-Nose System and Machine Learning on Exhaled Breath Samples.

In this paper, the first e-nose system coupled with machine learning algorithm for noninvasive measurement of total cholesterol level based on exhaled air sample was proposed. The study was conducted with the participation of 151 people, from whom a breath sample was collected, and the level of total cholesterol was measured. The breath sample was examined using e-nose and gas sensors, such as TGS1820, TGS2620, TGS2600, MQ3, Semeatech 7e4 NO2 and 7e4 H2S, SGX_NO2, SGX_H2S, K33, AL-03P, and AL-03S.

Ability assessment of the craniofacial structures radiological anatomy on panoramic radiography among dental student during pandemic of Covid-19. Ability assessment on OPG among dental student during pandemic of Covid-19.

Orthopantomography (OPG) is a routine imaging method in dental practice and an essential di- agnostic tool in dentistry. However, OPGs are challenging to interpret due to many overlapping structures. Graduates of dental schools should be aware of image distortions caused by various factors and be able to distinguish them from typical structures to make an accurate diagnosis.

A proposal for a database of sounds generated by temporomandibular joints and a tool for automateddiagnosisbasedonanRDC/TMDquestionnaire.

The prevalence of TMD indicates a need to develop new tools that are useful in the case of screening examinations. These methods can support diagnosis at the early stage of the disorder. The purpose of this research was to develop a comprehensive tool that would function as both a database of sounds generated by TMJ and as software which facilitates automated diagnosis.

A comparison of temporomandibular disorder headache in young adults in relation to perceived stress.

Chronic pain in the head and face region has a predicted prevalence of 20% in Europe, and is more common in women than men. The etiology of temporomandibular disorder (TMD) is multifactorial, and high levels of psychological stress amplify its symptoms. We were interested in how headache reported in RDC/TMD is associated with stress.

New Methods for the Acoustic-Signal Segmentation of the Temporomandibular Joint.

(1) Background: The stethoscope is one of the main accessory tools in the diagnosis of temporomandibular joint disorders (TMD). However, the clinical auscultation of the masticatory system still lacks computer-aided support, which would decrease the time needed for each diagnosis. This can be achieved with digital signal processing and classification algorithms.

The effect of root canal rinsing protocol on the push-out bond strength to the dentin cementation of the fiber post.

B a c k g r o u n d: Studies on the effect of root canal rinsing protocols on fiber post bonding to dentin are inconclusive. This study reports investigation of this topic. O b j e c t i v e s: to determine effects of irrigation protocol by means of a push-out test on the strength of adhesion between the post and dentin in an in vitro study.

A Novel Method of Temporomandibular Joint Hypermobility Diagnosis Based on Signal Analysis.

Despite the temporomandibular joint (TMJ) being a well-known anatomical structure its diagnosis may become difficult because physiological sounds accompanying joint movement can falsely indicate pathological symptoms. One example of such a situation is temporomandibular joint hypermobility (TMJH), which still requires comprehensive study. The commonly used official research diagnostic criteria for temporomandibular disorders (RDC/TMD) does not support the recognition of TMJH.

Candida prevalence and oral hygiene due to orthodontic therapy with conventional brackets.

Background: Conventional brackets are often used during orthodontic therapy of patients with malocclusion. The complex construction of such brackets greatly inhibits oral hygiene, which predisposes to increased carriage of microbiota. Orthodontic brackets could act as reservoir of yeast and predispose to oral candidosis.

Relationship between oral hygiene and fungal growth in patients: users of an acrylic denture without signs of inflammatory process.

Objectives: To answer to the following questions: is there any relationship between oral hygiene and the growth of yeast in patients without mucosal inflammation; and is there a need for mycological examination patients without mucosal inflammation?

Background: Patients with candidiasis may report varied symptoms, but such infections are most often asymptomatic. In addition to its high incidence in denture users (60%-100%), there is a concern that species from the oral cavity may colonize the upper gastrointestinal tract and lead to septicemia, which has a 40%-79% mortality rate and can require a prolonged hospital stay. It is thus important for all physicians to be aware of the risk factors, diagnosis, and treatment of oral candidiasis in older patients.

The Evaluation of Anthropometric Measurements of Young Polish Women's Faces.

Unlabelled: Face proportions are under constant evaluation during prosthetic or surgical diagnostics and treatment. The aim was to evaluate the proportions of the faces of young Polish women as compared with other ethnic groups.

Materials And Methods: The evaluation included 60 photographs of the faces of women, average age 17.

Relation between Headache and Mastication Muscle Tone in Adolescents.

Headache is a common problem in the population, which decreases the quality of life and makes everyday functioning difficult. It often coexists with typical symptoms of temporomandibular disorders. The objective of the study was to clarify whether there is a relationship between the presence of headache in young volunteers and the mastication muscle tone.

[Interdisciplinary surgical and prosthetic treatment of adenocarcinoma of the palate].

Introduction: The palatal mucosa requires careful testing prior to prosthetic treatment. Pathological changes may occur during the period of use of a dental prosthetic, especially when worn constantly. Aim of the report: We describe the case of a patient who experienced extensive changes in the mucosa of the hard palate over 12 years of dentures used.

Frequency of temporomandibular disorders diagnoses based on RDC/TMD in a Polish patient population.

Objective: To assess the frequency and age distribution of Axis I and Axis II diagnoses among Polish patients with temporomandibular disorders (TMD).

Method: One hundred sixty-three (n = 163) consecutive adult patients seeking TMD treatment were assessed based on the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) guidelines. Descriptive statistics on the frequency of diagnoses and mean age of the diagnostic groups was performed.
