This article highlights the importance of proper suturing of mucosa, gingiva, and skin after surgical procedures and trauma. Several factors play a role in promoting good healing, including optimal tension on the sutured wound, adequate blood flow, and careful selection of suture materials. The selected suture material depends on various factors, such as type of tissue, location of the wound, and healing time.

The oral mucosa is made up of an epithelium supported by the lamina propria and the submucosa. When the mucosa is damaged, wound healing is characterized by distinct, sequential phases. How does the healing process proceed? Both primary and secondary wound healing, encompasses haemostasis, inflammation, proliferation, and remodelling.

A 50-year-old woman presented at the outpatient clinic of the department of oral and maxillofacial surgery with a severe swelling around the left eye 1 week after removal of the second molar in the upper jaw. Despite administration of antibiotics 2 days after the removal of the molar because of periorbital swelling, the inflammation spread to the intraorbital space with eventual loss of the left eye. Timely recognition of the symptoms of (the onset of) an orbital infection after dental treatment and immediate referral to an oral and maxillofacial surgeon and/or ophthalmologist for adequate treatment can be vision-saving.

We developed a hybrid Monte Carlo self-consistent field technique to model physical gels composed of ABA triblock copolymers and gain insight into the structure and interactions in such gels. The associative A blocks of the polymers are confined to small volumes called nodes, while the B block can move freely as long as it is connected to the A blocks. A Monte Carlo algorithm is used to sample the node configurations on a lattice, and Scheutjens-Fleer self-consistent field (SF-SCF) equations are used to determine the change in free energy.

Purpose: This study determined the average distances and angles between anatomic landmarks within the orbit, with an emphasis on localization of the orbital process of the palatine bone. This information will help the surgeon with treatment planning and surgical procedures.

Patients And Methods: Four anatomic landmarks were identified retrospectively on computed tomograms of 100 adult Caucasian patients (50 men and 50 women): the top of the infraorbital margin superior to the infraorbital foramen (point A), the top of the orbital process of the palatine bone (point B), the anteriormost bony portion of the superior orbital fissure (point C), and the ventrolateral aspect of the bony entrance of the optic canal (point D).

Sodium dodecyl sulfate (SDS) is used to denature and solubilize proteins, especially membrane and other hydrophobic proteins. A quantitative method to determine the concentration of SDS using the dye Stains-All is known. However, this method lacks the accuracy and reproducibility necessary for use with protein solutions where SDS concentration is a critical factor, so we modified this method after examining multiple parameters (solvent, pH, buffers, and light exposure).

Triblock copolymers, with associative end-groups and a soluble middle block, form flower-like micelles in dilute solutions and a physical gel at higher concentrations. In a gel the middle blocks form bridges between domains/nodes that contain the ends. We combine the self-consistent field theory with a simple molecular model to evaluate the pair potential between the nodes.

Biodegradable fixation systems could reduce or eliminate the problems associated with removal of titanium plates. A multicenter randomised controlled trial (RCT) was performed in the Netherlands from December 2006-July 2009, and originally 230 injured and orthognathic patients were included. The patients were randomly assigned to either a titanium control group (KLS Martin) or to a biodegradable test group (Inion CPS).

In a recent RCT comparing biodegradable (Inion CPS) with titanium (KLS Martin) plates and screws for fixation of osteotomies or fractures, we found that in 21% of the cases the surgeon decided intra-operatively to switch from biodegradable to titanium. The aim of the current retrospective cohort study was to analyse the reasons for these switches in order to find predictor variables that may be helpful in the decision to use biodegradable devices or not. The surgeons' opinion about the biodegradable system, and if there was a learning curve in the application of the biodegradable system were also investigated.

Clear cell renal cell carcinomas are characterized by 3p loss, and by inactivation of Von Hippel Lindau (VHL), a tumorsuppressor gene located at 3p25. Recently, SETD2, located at 3p21, was identified as a new candidate ccRCC tumor-suppressor gene. The combined mutational frequency in ccRCC tumors of VHL and SETD2 suggests that there are still undiscovered tumor-suppressor genes on 3p.

The use of thin layers of a surface bound (polyelectrolyte) hydrogels for measuring the concentration of metal ions from electrolyte solutions is our motivation for modeling such hydrogels. The gels are composed of polymeric species with conformational degrees of freedom on the nanometer scale. The polymer conformations are affected by the presence of cross-links in the gel on a five to ten times larger length scale, and the repulsive interactions generated by the charges along the chains.
