Gingivitis is a highly prevalent oral condition that can be studied in humans via the 21‐d experimental gingivitis model, which allows for investigations into the induction and resolution of gingivitis. In this study, we used the autolysis of saliva as a source of peptides to predict the activity of human proteases in saliva during induction and resolution of inflammation. Healthy volunteers, with no remarkable oral or systemic conditions, were recruited into the study and stimulated saliva samples...

In the dental pulp surrounded by rigid dentinal walls, an increase in fluid volume will be followed by a rapid increase in interstitial fluid pressure. To maintain pressure homeostasis, a fluid drainage system is required. The dental pulp and apical periodontal ligament lack lymphatic vessels, and the questions are how the transport can take place inside the pulp and where the lymphatic vessels draining fluid from the apical periodontal ligament are located. The drainage of fluid within the pulp...

Cervicofacial infections of dental aetiology can be life-threatening and with the closure of dental practices following the onset of the COVID-19, it would be anticipated that their prevalence presenting to maxillofacial surgery would increase and services may be overwhelmed, with patients presenting later with a potential subsequent increase in morbidity. A retrospective analysis of patients with cervicofacial infection of dental aetiology referred to maxillofacial surgery during the initial six...

In the past, in the Oral and Maxillofacial (OMFS) department in Ninewells hospital Dundee, we have placed a tracheostomy in patients undergoing free flap surgery as the standard protocol. During the COVID pandemic this has changed. The patients now receive an extended intubation period the night of their surgery. Could this be a positive and a permanent change?

In 2018, NHS England released guidelines restricting the prescription of over-the-counter medicines (OTC). This was a project initially targeted at primary care, but we felt that it could also be used to improve services in secondary or tertiary care. We were interested to investigate our OTC prescribing pattern within a busy maxillofacial department and therefore carried out a service review. All outpatient prescriptions were reviewed between October 2017 and October 2018. The review was then repeated...

Achieving compression in the fracture line gap by open reduction and internal fixation leads to more primary bone healing and therefore hastens the healing process and patient's rehabilitation. We aimed to evaluate the application of compression by a modification in screw insertion in miniplates to improve the efficiency of the previous relevant methods. In this in vitro experimental study 20 sheep hemimandibles were prepared. Following intentional fracturing of the hemimandibular bodies, the specimens...

Lower eyelid retraction or ectropion bring suffering to the patients both physically and mentally. Efforts to explore pertinent surgical treatments are still needed. Here we have described our preferred surgical technique for lower eyelid ectropion repair with pre-expanded island forehead flaps or pedicled forehead flaps. Between July 2007 and March 2017, a retrospective review of 12 patients who suffered from cicatricial lower eyelid ectropion as a result of trauma, surgery, or infection was conducted.

We thank Chavez-Rimache et al. for their letter, in which they highlighted the importance of further study into acute steroid administration to patients with odontogenic cervicofacial infections. As they highlighted, existing systematic reviews and meta-analysis of other head and neck conditions suggest benefits with few side effects.

The 8th edition of the UICC TNM (UICC 8) staging rules for oropharyngeal squamous cell carcinoma (OPSCC) acknowledges dichotomous disease biology based on the human papillomavirus (HPV) tumour status. This retrospective study was undertaken to validate those staging rules in a single UK treatment centre. Given a recent resurgence of interest in primary surgery for OPSCC, a secondary objective was to identify subsets of patients who might benefit. Patients presenting with OPSCC between 2010 and 2017...

The use of corticosteroids as a combined therapy with antibiotics in deep cervicofacial infections of odontogenic origin is controversial. On one hand, it is considered that parenteral administration of high doses of corticosteroids, once or twice, can improve recovery in trismus, reducing pain as a result of its anti-inflammatory effect. On the other hand, there is concern regarding its adverse effects, such as immunosuppression, which could also aggravate the infection by weakening the immune response.

A 48-year-old blacksmith presented to A&E after sustaining facial injuries while operating a metal punch press. Radiographs revealed the presence of a metallic foreign body within the cheek, but this was clinically impalpable. By using a neodymium rare earth magnet extraorally, it was possible to identify the position of the fragment several centimetres lateral to the entry wound. Triangulation of the fragment's position allowed retrieval under local anaesthetic through the original penetration...

When patients attend the emergency department with facial fractures that require surgery and are immediately admitted, surgery can be delayed as theatre time is prioritised for other more urgent patients. One solution is to send the patient home and admit them as an elective patient at a later date. The aim of this study was to investigate the outcomes of patients admitted directly and those seen as elective patients following fracture of the mandible or zygomatic complex. Data were taken from the...

Abstract Objectives Increasing evidence suggests that aberrant expression of microRNAs (miRNAs) is involved in the pathogenesis of primary Sjögren’s syndrome (pSS). The aim was thus to characterize the miRNA profile in saliva, salivary gland tissue, and plasma from patients with pSS and compare findings with those of patients having Sjögren‐like disease (non‐pSS). In addition, to correlate miRNA levels and clinicopathological features of pSS. Methods miRNA real‐time quantitative polymerase...
