BACKGROUND: Masticatory muscle-pain patients often complain about sensorimotor changes, but the effects of pain on the psychophysical properties remain unclear. This study aimed to investigate the effects of Delayed-Onset Muscle Soreness (DOMS) on the jaw's position sense (PS) and occlusal sensitivity (OS). METHODS: Twelve participants underwent intense concentric-eccentric jaw exercises. Self-reported muscle fatigue and pain, pain-free maximum mouth opening (MMO), pain pressure thresholds (PPTs) at right and left masseter and right and left anterior temporalis, maximum voluntary bite force (MVBF), PS, and OS were recorded before, immediately after, 24h, 48h, and one week after the exercises...

Control over the integrative self-sorting of metallo-supramolecular assemblies opens up possibilities for introducing increased complexity and function into a single self-assembled architecture. Herein, the relationship between the geometry of three ligand components and morphology of three self-sorted heteroleptic [Pd2 L2 L'2 ](4+) cages is examined. Pd-mediated assembly of two bis-monodentate pyridyl ligands with native bite angles of 75° and 120° affords a cis-[Pd2 L2 L'2 ](4+) cage while the same reaction with two ligands with bite angles of 75° and 60° gives an unprecedented, self-penetrating structural motif; a trans-[Pd2 (anti-L)2 L'2 ](4+) heteroleptic cage with a "doubly bridged figure eight" topology...

The role of capnography in esophagogastroduodenoscopy (EGD) is controversial. Simultaneous supplemental oxygen, position of patient, open mouth breathing pattern, and anatomy of the oral and nasal cavity can influence capnography accuracy. This study first measured capnographic data via the nasal or oral cavity during sedated EGD. Secondly, we investigated the influence of supplementary oxygen through the oral cavity on the capnographic reading. Patients with ASA class I or II status admitted for routine EGD exams were enrolled...

BACKGROUND: A link between progressive dental malocclusion, the use of a continuous positive airway pressure mask and GH-secreting pituitary macroadenoma (acromegaly) has not been previously reported. The present clinicopathological analysis stresses that tooth malposition should not be seen exclusively as a local process. CASE PRESENTATION: A 62-year-old caucasian man with no relevant medical history reported difficulty chewing food and perceived voice alteration during his annual periodontal check-up...

Children with low levels of thyroid hormones (hypothyroidism) have delayed tooth eruption, enamel hypoplasia, micrognathia, and anterior open bite, whereas children with hyperthyroidism may suffer from accelerated tooth eruption, maxillary, and mandibular osteoporosis. However, it is still unknown whether thyroid function variations within the normal or subclinical range also have an impact on hard dental tissues in healthy children. The objective of this study was, therefore, to investigate the association between thyroid function from the fetal period until early childhood and dental development at school age...

Orthodontic treatment in adult patients with a skeletal discrepancy can be challenging. In this case report, we achieved both sagittal and vertical control by combining the classic sliding mechanics straight-wire technique with miniscrew anchorage. We treated a 21-year-old Chinese woman with a severe high mandibular plane angle, a retrusive chin, and a gummy smile. Her diagnosis included a skeletal Class II skull base with a mild anterior open bite, a protrusive maxilla, and a backwardly rotated mandible. This case underscores the importance of anchorage control in both the sagittal and vertical directions...

This clinical case report presents the nonsurgical orthodontic treatment of a patient with skeletal Class II malocclusion, posterior crossbite, anterior open bite, accentuated dental discrepancies in both arches, and an odontoma. The proposed treatment involved maxillary expansion, extraction of atypical maxillary lateral incisors and mandibular first molars, and intrusion of maxillary teeth with the aid of mini-implants. The results obtained with these procedures included good tooth alignment, normal overbite and overjet, removal of the odontoma, and a harmonious smile...

Fine-tuning communication is well documented in mammalian social play which relies on a large variety of specific and non-specific signals. Facial expressions are one of the most frequent patterns in play communication. The reciprocity of facial signals expressed by the players provides information on their reciprocal attentional state and on the correct perception/decoding of the signal itself. Here, for the first time, we explored the Relaxed Open Mouth (ROM), a widespread playful facial expression among mammals, in the South American sea lion (Otaria flavescens)...

In open bite case treatments, a proper diagnostic differentiation is essential in determining the appropriate corrective procedures. Dental open bites are generally more responsive to treatment with orthodontics alone, whereas skeletal open bites often require a combination of orthodontics and orthognathic surgery. Patient selection and treatment principles for non-surgical open bite treatment routinely include fixed appliances both labial or lingual. However, removable clear aligners have gained a consistent popularity in the treatment of complex cases including open bite malocclusions...

Snake venom metalloproteases (SVMPs) are members of the a disintegrin and metalloprotease (ADAM) family of proteins, as they possess similar domains. SVMPs are known to elicit snake venom-induced haemorrhage; however, the target proteins and cleavage sites are not known. In this work, we identified a target protein of vascular apoptosis-inducing protein 1 (VAP1), an SVMP, relevant to its ability to induce haemorrhage. VAP1 disrupted cell-cell adhesions by relocating VE-cadherin and γ-catenin from the cell-cell junction to the cytosol, without inducing proteolysis of VE-cadherin...
