The pandemic of the 21st century had a significant influence on the lives of the world population in a negative way. This situation determined a change of lifestyle; it caused the necessity of social isolation for a great number of people. In fact, people tended to avoid crowded environments, social events, to reduce medical checks and sports activities, favoring sedentary life because of fear of the virus. Read More

This case describes the treatment of syngnathia with a popliteal-pterygium syndrome. Although short-term successful surgical treatment has been described in literature, long-term follow up is essential, as the mouth opening limitations can be repetitively reoccurring. This requires new, individual treatment strategies as demonstrated in this case. Read More

The clinical syndrome known as posterior bite collapse (PBC) consists of multiple, often pathognomonic factors that deviate from normal, or an occlusion wherein the posterior occlusion is compromised and may ultimately destroy the functional protective capacity of the entire dentition. Secondary clinical sequelae may include accelerated periodontitis progression, temporomandibular disorders (TMD), increasing mobility/fremitus, additional tooth loss, anterior flaring, and loss of occlusal vertical dimension. Etiologic factors may include tooth loss without replacement, orthodontic malocclusions and dentoskeletal disharmonies, periodontitis, accelerated retrograde occlusal/interproximal wear, severe caries, or iatrogenic and conformative dentistry.

Chronic pain imposes a significant burden to the healthcare system and adversely affects patients' quality of life. Traditional subjective assessments, however, do not adequately capture the complex phenomenon of pain, which is influenced by a multitude of factors including environmental, developmental, genetic, and psychological. Quantitative sensory testing (QST), established as a protocol to examine thermal and mechanical sensory function, offers insight on potential mechanisms contributing to an individual's experience of pain, by assessing their perceived response to standardized delivery of stimuli.

Abstract: Temporomandibular joint (TMJ) ankylosis in children can alter facial development and affect oral hygiene and function. Surgical release of the ankylosis is the mainstay of treatment. The authors hypothesize that preoperative arterial coil embolization is safe and effective in preventing major blood loss during TMJ surgery (loss prompting blood transfusion or hemodynamic instability requiring vasoactive medication administration) in children with TMJ ankylosis.

Background: Ankylosis of the temporomandibular joint (TMJ) is a pathological disorder which results in patients' limited or even complete failure of mouth opening. When TMJ ankylosis occurs during the growing age, moderate to severe micrognathia might be the proposed scenario of such cases, accompanied by obstructive sleep apnea and hypopnea syndrome (OSAHS). TMJ reconstruction using total TMJ prostheses with mandibular advancement (MA) can simultaneously improve the function and aesthetic profile of such patients. Read More
