Obstructive sleep apnea syndrome (OSAS) is a respiratory disorder affecting up to 49 % and 23 % of middle to older aged men and women respectively. CPAP (continuous positive airway pressure) is the gold-standard treatment for severe apneas. In mild and moderate forms of OSAS, mandibular advancement devices (MAD) are equally a first line of treatment. Both CPAP and MAD have their advantages and side effects. Patient tolerance to these two therapies varies according to different patient-parameters. In order to guide physicians and patients in choosing between these two treatments, we present a description of both treatment modalities.Sjögren Syndrome is an autoimmune disorder presenting as Sicca syndrome (dry-eye, dry mouth) and most often multiorgan involvement with various clinical manifestations. The diagnostic criteria defined by the American College of Rheumatology (ACR) and the European League Against Rheumatism (EULAR) include biologic, histologic parameters and functional measurements. Part of this workup can be performed by the ENT specialist. It encompasses minor salivary gland biopsy, sialometry, Schirmer lacrymal test and major salivary gland ultrasound. These tests and their performances are described. The growing importance of major salivary gland ultrasound as a follow-up and diagnostic tool is also discussed in this article.A quarter of cutaneous melanomas occur on the head and neck. Despite close collaboration between the dermatology, oncology, pathology, nuclear medicine and otorhinolaryngology departments, the survival of patients presenting with this type of melanomas remains inferior to that of other parts of the body. learn more The morbidity of head and neck surgery significantly alters the quality of life. Therefore, specific multidisciplinary expertise is required. We present here the specificities of ENT management.For safe procedures, the surgeon performing thyroid gland surgeries must know precisely the anatomical relationships of the inferior laryngeal nerve with other cervical structures, in particular the inferior laryngeal artery and its branches. Classic descriptions of these relationships are based almost exclusively on the observation of Caucasian populations. However, this study shows that there are important differences between Caucasian and Sub-Saharian ethnic group, differences that any surgeon having the opportunity to operate in Africa should know to limit the risk of iatrogenic nerve damage and its morbid consequences.The surgical management of unilateral and bilateral vocal cord paralysis depends on the severity of the condition, the potential for spontaneous recovery, the patient's age and vocal expectations. link2 Standardized re-innervation surgeries, unilateral non-selective and bilateral selective, are viable alternatives to static procedures currently under evaluation in prospective studies. Neurorraphy of the ansa cervicalis loop to the recurrent laryngeal nerve allows lasting vocal recovery and potentially superior results to medialization and thyroplasty, by maintaining the visco-elastic properties of the vocal cord and preventing its atrophy. Selective bilateral reinnervation shows potential for recovery of inspiratory abduction with improved respiratory function without vocal deterioration.

To study the potential benefits of a post-cure thermal treatment on key physico-mechanical properties of light-cured resin-based composites for use in indirect restorations, a CAD/CAM composite block being used as control.

Six commercial composites were light-cured before being thermally treated in a furnace at 90°C during 15 minutes (CAD/CAM composite used as a control). The properties measured with or without thermal treatment were degree of conversion, flexural strength, elastic modulus, Vickers microHardness, organic mass content and eluted and absorbed mass before and after storage in ethanol. The data were analysed using one-way ANOVA, and Weibull distributions.

A general increase in the properties measured was observed for all materials after thermal treatment, except a general decrease in mass elution and absorption (most statistically significant p⟨0.05). Weibull analysis showed a tendency (p⟩0.05) of increased reliability of the flexural strength after thermal treatment for all materials.

The present data revealed clear physico-mechanical improvements after thermal treatment of light-cured composites. Such method could hence be beneficially used to produce indirect restorations as compared to stratifying and light-curing the same composites in situ. However, most properties of the control CAD/CAM composite were higher, but CAD/CAM technologies aren't available everywhere.

The aim was to identify heavy users of public health (PHS) and public oral health (POHS) services and combined and concurrent users of these services.

Numbers of 18+ year-old patients and their visits to POHS (12,124 patients) and PHS (28,479 patients) were collected from two patient registers in a Finnish town in 2013. The combined dataset consists of 32,481 patients. Using a highest decile criterion for both for POHS and PHS, those patients who had made 8 or more visits were categorised as heavy users. Patients who had made total of 10 or more visits to the POHS and/or PHS were categorised as combined heavy users. Patients who had made 8 or more visits to both the POHS and PHS were categorised as concurrent heavy users (195 patients).

Heavy users of POHS were more often men and those of PHS more often women. Combined heavy users were likely to be women and to be older. The combined heavy users accounted for 40% of all visits of POHS and/or PHS. Among them 30% did not have any POHS visits and 4% did not have any PHS visits. Concurrent heavy use was rare, involving 0.06% of all patients, but made 3.4% of all visits.

Of the patients making 10 or more POHS and/or PHS visits, only five percent were concurrent heavy users of both services. As many non-communicable diseases share common risk factors the combined heavy users of PHS should be directed to use POHS and vice versa.

The study sought to explore the consent rate and associated potential bias across a cohort in a large longitudinal population based study.

Data were taken from a study designed to examine the effects of the reintroduction of community water fluoridation on children's oral health over a five-year period. Children were recruited from a fluoridated and non-fluoridated area in Cumbria, referred to as Group 1 and Group 2.

Data were available for 3138 individuals. The consent rate was 12.91 percentage points lower in Group 2 than Group 1 (95% CI -16.27 to -9.56, p⟨0.001). The population in Group 2 was more deprived (higher Index of Multiple Deprivation (IMD)) than Group 1 before consent was taken. Consent was not associated with deprivation in either group.

The cohort appeared to be unaffected by IMD-related non-consent. However there was a difference in consent rate between the two groups. With the population in Group 1 being more deprived than Group 2, it will be important to incorporate these differences into the analysis at the end of this longitudinal study.

Materials and Methods From a prepared typodont-tooth (#36), ten CAD/CAM provisional polymethylethacrylate crowns were fabricated with the E4D system. Each provisional crown had its occlusion adjusted. They were scanned (E4D) and the .stl files of the crown preparations were merged with the files from the adjusted crowns (3 shape software) to produce ten polished monolithic zirconium oxide crowns. For comparison, provisional and monolithic zirconium oxide crowns were scanned (True-Definition scanner), the .stl files aligned, converted into a normalized 76x76-matrix, analyzed with ANOVA with repeated measures and Tukey's test. To generate deviation distribution tables and difference plots, .stl files (provisional crowns and monolithic zirconium oxide crowns) were merged with Geomagic software. Results There were significant differences between provisional crowns and monolithic zirconium oxide crowns. The differences were manly in the fissure area. 86% of the calculated deviations were between + 0.06mm and - 0.04mm, 42.4% of all data points were within ± 0.022mm with a SD of 0.005mm. The main differences were in the fissures, requiring clinically none or only minimal occlusal adjustments for these zirconium oxide crowns.The objective of this study was to evaluate the use of naphazoline hydrochloride in comparison with aluminum chloride for vertical gingival displacement. The inclusion criteria were patients with a good general systemic condition; periodontal health; and thick gingival biotype. Moreover, the exclusion criteria were smoking individuals; canine teeth or central incisors with carious lesions, abrasion, erosion, prosthetic abutments or unsatisfactory restorations; patients with periodontal disease; and users of continuous medication. 72 teeth were included and the Square Block Design was used to randomize the samples. Three measures were obtained from each tooth, and mean vertical gingival displacement was calculated. A descriptive analysis of the average displacement was performed. The normality test used was the Lilliefors' Test and for comparison between treatments, the Kruskal-Wallis Test was used. The Bartlett's Test for homogeneity of variances was used and a 5% (p ⟨ 0.05) significant level was considered. Thus, the Aluminum Chloride and Naphazoline Hydrochloride showed no statistically amount of gingival retraction than the control group (p = 0.3822). The average of gingival vertical displacement in all groups were less than 0,5 mm. link3 The technique used did not allow any amount of horizontal displacement on obtained models.

Oral squamous cell carcinoma (OSCC) is the most prevalent form of oral cancer. Very few researches have been carried out for the automatic diagnosis of OSCC using artificial intelligence techniques. Though biopsy is the ultimate test for cancer diagnosis, analyzing a biopsy report is a very much challenging task. To develop computer-assisted software that will diagnose cancerous cells automatically is very important and also a major need of the hour.

To identify OSCC based on morphological and textural features of hand-cropped cell nuclei by traditional machine learning methods.

In this study, a structure for semi-automated detection and classification of oral cancer from microscopic biopsy images of OSCC, using clinically significant and biologically interpretable morphological and textural features, are examined and proposed. Forty biopsy slides were used for the study from which a total of 452 hand-cropped cell nuclei has been considered for morphological and textural feature extraction and further analysis.
