Chemical-physical characteristics of artificial saliva substitutes: rheological evaluation.

Objective: We aimed at evaluating some chemical-physical properties of artificial saliva substitutes easily available on the E.U. market, such as viscosity, pH, buffering capacity, superficial tension, density and spinnbarkeit and to compare the results with human natural saliva bibliographic data.

Temporomandibular disorders and neck pain in primary headache patients: a retrospective machine learning study.

Objectives: To evaluate the linkage underpinning different clinical conditions as painful TMD and neck pain in patients affected by primary headaches.

Materials And Methods: In this machine learning study, data from medical records of patients with headaches as migraine, tension-type headache (TTH) and other primary ones, referring to a University Hospital over a 10-year period were analysed. VAS was used to evaluate the intensity of the TMD and neck pain.

Periodontal Disease and Vitamin D Deficiency in Pregnant Women: Which Correlation with Preterm and Low-Weight Birth?

Periodontal disease seems to be correlated with low vitamin D serum levels, preterm birth (PTB) and low birth weight (LBW), although the literature still lacks a consensus. This study aimed to investigate this correlation in a cohort of pregnant women over 20 weeks of gestation from the University Hospital "Maggiore della Carità", Novara, Italy. We assessed serum levels of vitamin D and oral health status through the following indexes: Oral Hygiene Index (OHI), Plaque Control Record (PCR), Gingival Bleeding Index (GBI), and Community Periodontal Index of Treatment Needs (CPTIN).

Changes in salivary flow rate and pH in pregnancy.

Objective: To evaluate changes in pH and Flow Rate (FR) of the Unstimulated Whole Saliva (UWS) in a sample of pregnant women in different gestational periods.

Patients And Methods: After collecting demographic data and medical histories, as well as conducting an oral examination, a sample of pregnant women were instructed on how to prepare prior to the sample collection. At a time between 11.

Functional status and oral health in patients with amyotrophic lateral sclerosis: A cross-sectional study.

Background: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease affecting upper and lower motor neurons. The current practice of caring for patients affected by ALS involves a multidisciplinary team without any indication about oral health care.

Objective: We sought to investigate the functional status and oral health in patients with ALS to define a specific multidisciplinary management.

Salivary pH and flow rate in menopausal women.

Objective: This study aims at determining pH and Flow Rate (FR) of Unstimulated Whole Saliva (UWS) in a sample of 120 ♀ (60 menopausal women and 60 healthy fertile women with similar mean age); detecting the DMFT index (Decayed, Missing, Filled Teeth index) and evaluating any correlations between pH, FR, age and DMFT.

Patients And Methods: Concerning the day before sample collection, patients were advised to keep a relaxed attitude and not to practice sports. They were also told to not eat or drink during the hour preceding sampling procedures.

Evaluation of salivary surface tension in a cohort of young healthy adults.

Objective: To determine salivary pH, flow rate (FR) and surface tension (γs) in a cohort of 30 healthy young adults. To acquire cohort biological independent variables (age, gender, weight, height, medications, smoking, pathologies, and allergies) and to correlate them with pH, FR and γs obtained values. Evaluate the possible variation of the γs values during the time after the withdrawal and the influence of the operational abilities of the experimenting operators.

Salivary flow rate and pH in patients with oral pathologies.

Objective: Determine salivary pH and flow rate (FR) in a sample of 164 patients who came to Oral Pathology ambulatory, 84 suffering from oral lesions and 80 without oral lesions. Another aim was to evaluate factors that influence salivary flow rate.

Patients And Methods: Subjects underwent clinical examination and completed an anamnestic questionnaire in order to obtain useful information that was used to classify participants in different groups.

Determination of breath alcohol value after using mouthwashes containing ethanol in healthy young adults.

Objective: To evaluate breath alcohol value and blood alcohol concentration after using mouthwashes containing ethanol in a panel of healthy young adults. To determine zeroing time of these values and if subjects' body mass index or gender influenced it. Breathalyzer test is a practice performed to detect alcohol-impaired-drivers that can be penalized.

Kinematic viscosity of unstimulated whole saliva in healthy young adults.

Objective: To analyze kinematic viscosity and pH of unstimulated whole saliva, evaluate possible variations after sampling, identify any gender differences and detect possible correlations between them.

Subjects And Methods: The sample consisted of sixty-four healthy young adults (37 females and 27 males, mean age 25.2 years).

Daily and annually variation of unstimulated whole saliva flow rate and pH and their relation with body profile in healthy young adults.

Aim: To analyse pH and flow rate (FR) of unstimulated whole saliva (UWS), detecting their possible correlations both among themselves and with body profile; in addition to identify daily, annually and gender differences.

Materials And Methods: Eighty-one (47 ♀; 34 ♂) healthy young adults (mean age 22.7±4.

High prevalence of human cytomegalovirus in a population of periodontally healthy subjects.

Background: Human cytomegalovirus (HCMV) appears to be more frequent in periodontally affected patients than in healthy control groups. Based on this assumption, it has been suggested that HCMV may play a role in the pathogenesis of periodontal disease.

Objective: The objective of this uncontrolled study was to assess the occurrence of HCMV in a large unselected population of periodontally healthy subjects.

Mental health in patients with systemic sclerosis: a controlled investigation.

Background: Despite the undeniable impact of systemic sclerosis (SS) on quality of life, only a few studies so far have focused on its psychiatric or psychological aspects. We aimed at assessing psychiatric symptoms and self-image in inpatients with SS and comparing them with patients with either a very mild skin condition or a serious skin condition.

Methods: Three groups were recruited: (i) 38 consecutive female inpatients with SS; (ii) 38 age-matched female outpatients with melanocytic naevi; (iii) 35 age-matched female inpatients with melanoma.

Incisor and mandibular movement during retrusion.

Human mastication, respiration, speech, swallowing and suckling are directed by the jaw muscle activites, the temporo-mandibular joints, the ligaments and by the occlusal dental contacts. Mastication is usually assessed by border movements of the mandibular incisors. While the border movements of opening, protrusion and lateratrusion are often used to determine the mandibular functions, the movement of retrusion is rarely considered in the study of the human oro-facial functions.

Psoriasis, stress and psychiatry: psychodynamic characteristics of stressors.

The aim of this investigation was to learn how a stressful event, often very mild, can determine a relapse of psoriasis. The research was carried out with clinical interviews and with the administration of Rorschach Psychoreactive, MMPI and H-T-P tests to 80 in-patients. Our data revealed a high prevalence of psychic disorders: 71.

Characteristics and possible significance of the answers to Rorschach from patients suffering from psoriasis.

The authors have tried to ascertain the statistical significance of the differences between the answers to H. Rorschach Psychodiagnostic tests given to 80 male and female adult patients, suffering from psoriasis and by 'normal' patients. The absolute frequencies and the averages of the results concerning 55 items obtained through the administration of Rorschach to patients with psoriasis were compared with the results of the test made to the general population.
