Review
Infections of orbit and periorbita are frequent, leading to significant morbidity. Orbital cellulitis is more common in children and young adults. At any age, infection from the neighboring ethmoid sinuses is a likely cause and is thought to result from anatomical characteristics like thin medial wall, lack of lymphatics, orbital foramina, and septic thrombophlebitis of the valveless veins between the two. Other causes are trauma, orbital foreign bodies, preexisting dental infections, dental procedures, maxillofacial surgeries, Open Reduction and Internal Fixation (ORIF), and retinal buckling procedures. The septum is a natural barrier to the passage of microorganisms. Orbital infections are caused by Gram-positive, Gram-negative organisms and anaerobes in adults and in children, usually by Staphylococcus aureus or Streptococcus species. Individuals older than 15 years of age are more likely to harbor polymicrobial infections. Signs include diffuse lid edema with or without erythema, chemosis, proptosis, and ophthalmoplegia. It is an ocular emergency requiring admission, intravenous antibiotics, and sometimes surgical intervention. Computed tomography (CT) and magnetic resonance imaging (MRI) are the main modalities to identify the extent, route of spread from adjacent structures, and poor response to intravenous antibiotics and to confirm the presence of complications. If orbital cellulitis is secondary to sinus infection, drainage of pus and establishment of ventilation to the sinus are imperative. Loss of vision can occur due to orbital abscess, cavernous sinus thrombosis, optic neuritis, central retinal artery occlusion, and exposure keratopathy, and possible systemic sequelae include meningitis, intracranial abscess, osteomyelitis, and death. The article was written by authors after a thorough literature search in the PubMed-indexed journals.

This study aimed to evaluate the effectiveness of conventional occlusal analysis in contrast with digital occlusal analysis in natural dentition. Occlusal analysis allows the identification of normal and abnormal occlusal contact points that alter the craniomandibular cervical system. We searched for articles with keywords [[dental occlusion]], [[natural dentition]], [[occlusal adjustment]], [[Immediate Complete Anterior Guidance Development]] [[mastication]], [[bite force]], [[premature contact]], [[occlusal balance]] [[articulating paper]]], [[spray]], [[Occlusal contacts]], and [[bite strength]]. They were considered observational , odds ratio and case control studies. We found 189 items. After evaluating the abstracts and full texts of the articles, 10 papers met the inclusion criteria. It was found that occlusal analysis allows the identification of the relationship between poor occlusion and the sensitivity of the teeth due to occlusal trauma, which is also related to temporomandibular joint pain in dynamic occlusion. The contacts of greater strength were observed in nonfunctional cusps, 48%, without ruling out the functional cusps, 24%. Despite being the universal method of occlusal control to date, the use of joint paper, remains subjective compared to the digital occlusal control device. Posture is considered directly related to occlusal trauma and temporomandibular disorders; without proper occlusal analysis, a clear diagnosis of the patient's joint condition cannot be obtained. Digital occlusal analysis is more objective than traditional occlusal analysis.

Review
In Denmark, approximately 700 patients with ischaemic stroke and large vessel occlusion are treated annually with mechanical thrombectomy (MT). Treatment is proven up to 24 hours if the patients still have salvageable brain tissue and includes patients with occlusions in the anterior and posterior cerebral circulation, and with large volume infarcts. Future studies may expand the treatment indication, as argued in this review. Danish national data on MT have shown that the implementation in daily clinical routine is as effective and safe as reported in the randomized clinical trials.

Stainless steel crowns (SSCs) are the preferred restoration of pediatric dentists for children requiring a pediatric dental rehabilitation due to their low cost and durability. Despite low technique sensitivity SSC placement can be challenging in some clinical situations including when placed on primary canines. Primary canines restored with SSCs often result in premature contacts and posterior open bite making acquiring an "as the patient presented" (ATPP) occlusion difficult when providing a pediatric dental rehabilitation. Opening of the posterior occlusion due to premature canine contact in a dental rehabilitation is often viewed as unavoidable. This technique article describes a simple method to address this clinical situation and reviews basic principles and techniques for placing SSCs.
