Citizen science to improve patient and public involvement in GUideline Implementation in oral health and DEntistry (the GUIDE platform).

Background: Citizen science is a way to democratise science by involving groups of citizens in the research process. Clinical guidelines are used to improve practice, but their implementation can be limited. Involving patients and the public can enhance guideline implementation, but there is uncertainty about the best approaches to achieve this.

Do electronic cigarette devices/vapes impact the colour of dental ceramics?

Design: In vitro primary research study.

Case Selection And Method: Five frequently used restorative dental ceramic materials (pressable ceramics (PEmax), pressed and layered ceramics (LEmax), layered zirconia (LZr), monolithic zirconia (MZr) and porcelain fused to metal (PFM)) were selected and manufactured in shade A1. Samples of each material were prepared in discs and kept in water at 37°C for 24 hours then aged via thermocycling.

Are zirconia crowns the superior choice when restoring primary posterior molars?

Data sources Electronic database searches were carried out using predefined search terms using Embase, Google Scholar, Medline, The Cochrane Library, The Cochrane Central Register of Controlled Trials and Latin American and Caribbean Health Sciences Literature. The Trip medical database was also used to identify randomised control trials investigating stainless steel and zirconia crowns. Studies published from 1 January 2000 until 6 June 2021 were included, and reference lists of included studies analysed to ensure data saturation along with grey literature searches.

Clinical and radiographic assessment and restoration of maxillary sinus function in relation to oro-antral fistula closure: a systematic review.

Background: The purpose of this study was to determine current practice in assessment of maxillary sinus health during oro-antral fistula closure.

Method: A systematic review using specific MeSH headings between 1990 and September 2021 on Medline, Ovid, and PubMed was performed. The inclusion criterion was closure of oro-antral fistula in adult patients.

Obstetric and Newborn Weak D-Phenotype RBC Testing and Rh Immune Globulin Management Recommendations: Lessons From a Blinded Specimen-Testing Survey of 81 Transfusion Services.

Context.—: Modern RHD genotyping can be used to determine when patients with serologic weak D phenotypes have RHD gene variants at risk for anti-D alloimmunization. However, serologic testing, RhD interpretations, and laboratory management of these patients are quite variable.

Pulpotomy for the Management of Irreversible Pulpitis in Mature Teeth (PIP): a feasibility study.

Background: Progression of dental caries can result in irreversible pulpal damage. Partial irreversible pulpitis is the initial stage of this damage, confined to the coronal pulp whilst the radicular pulp shows little or no sign of infection. Preserving the pulp with sustained vitality and developing minimally invasive biologically based therapies are key themes within contemporary clinical practice.

CORE OUTCOME SETS AND DENTAL PATIENT REPORTED OUTCOMES.

In clinical research, outcomes are the results or 'endpoints' that are measured to assess whether clinical interventions have been successful or whether one treatment works better than another. There are a vast number of outcomes that have been reported in dental trials; the number, diversity and questionable relevance of these outcomes can lead to research wastage. Ultimately, this can lead to uncertainty for patients and dental professionals as to the most effective prevention and treatment options available as the evidence available may not use outcomes important to them.

Developing a core outcome set for periodontal trials.

Background: There is no agreement which outcomes should be measured when investigating interventions for periodontal diseases. It is difficult to compare or combine studies with different outcomes; resulting in research wastage and uncertainty for patients and healthcare professionals.

Objective: Develop a core outcome set (COS) relevant to key stakeholders for use in effectiveness trials investigating prevention and management of periodontal diseases.

Interventions for treating cavitated or dentine carious lesions.

Background: Traditionally, cavitated carious lesions and those extending into dentine have been treated by 'complete' removal of carious tissue, i.e. non-selective removal and conventional restoration (CR).

Selective Caries Removal in Permanent Teeth (SCRiPT) for the treatment of deep carious lesions: a randomised controlled clinical trial in primary care.

Background: Dental caries is one of the most prevalent non-communicable disease globally and can have serious health sequelae impacting negatively on quality of life. In the UK most adults experience dental caries during their lifetime and the 2009 Adult Dental Health Survey reported that 85% of adults have at least one dental restoration. Conservative removal of tooth tissue for both primary and secondary caries reduces the risk of failure due to tooth-restoration, complex fracture as well as remaining tooth surfaces being less vulnerable to further caries.

How can local anaesthesia be improved in the management of irreversible pulpitis?

Background Pain management in endodontic treatment is often managed with local anaesthetic, occasionally supplemented with oral medication. Currently, there is little evidence to suggest the best combination of local anaesthetic and oral medication to provide optimal pain control in symptomatic irreversible pulpits. A network meta-analysis was carried out to identify the best agent/technique for pulpal anaesthesia in both the maxilla and mandible in irreversible pulpits.

Does a history of periodontal disease affect implant survival?

Data sources Three electronic databases were searched (Medline, EMBASE and Cochrane Central) with date of publication between January 2003 and May 2018. Only articles written in English were included. Following electronic searches, the authors conducted manual searches of oral implant/periodontal journals from January 2012 to May 2018.

Heterogeneity in Approaches for Switching From Universal to Patient ABO Type-Specific Blood Components During Massive Hemorrhage.

Context.—: ABO mistransfusions are rare and potentially fatal events. Protocols are required by regulatory agencies to minimize this risk to patients, but how these are applied in the context of massive transfusion protocols (MTPs) is not specifically defined.

Examining the impact of oral hygiene advice and/or scale and polish on periodontal disease: the IQuaD cluster factorial randomised controlled trial.

Objective To compare the clinical effectiveness and cost benefit of different frequencies of scale and polish (S&P) treatments in combination with different types of oral hygiene advice (OHA).Design Multi-centre, multi-level cluster randomised factorial open trial with blinded outcome evaluation. UK dental practices were cluster randomised to deliver OHA as usual or personalised.

A comparison of techniques for the explantation of osseointegrated dental implants.

Data sources A search of electronic databases (Embase and PubMed) was carried out along with manual and grey searches of published and unpublished journals. Publication year was from first available until 23 August 2018.Study selection Titles and abstracts from the original search were reviewed by two authors.

Do viruses play a role in peri-implantitis?

Data sources A search of electronic databases (EMBASE, MEDLINE, Cochrane Oral Group Trials Register and the Cochrane Central Register of Controlled Trials) along with a manual search of various Science Citation Indexed journals.Study selection Four cross-sectional studies and one case-control study were included where percentage levels of Herpes Simplex Virus Type 1 (HSV1), Epstein-Barr Virus (EBV) and Cytomegalovirus (CMV) were sampled for in both peri-implantitis affected and healthy implant sites, with the latter used as the control. Studies were excluded that investigated any other infective agent, had fewer than ten participants, was performed in vitro or involved subjects with only periodontal disease.

Small Bowel Diverticulosis: Pathogenesis, Clinical Management, and New Concepts.

Purpose Of Review: Small bowel diverticulosis is a well-known clinical entity whose diagnosis and management has evolved in recent years. This review covers pathophysiology, incidence, and prevalence, and it also provides an update on modern diagnosis and management. Meckel's diverticula are covered elsewhere in this volume.

WITHDRAWN: Operative caries management in adults and children.

Background: The management of dental caries has traditionally involved removal of all soft demineralised dentine before a filling is placed. However, the benefits of complete caries removal have been questioned because of concerns about the possible adverse effects of removing all soft dentine from the tooth. Three groups of studies have also challenged the doctrine of complete caries removal by sealing caries into teeth using three different techniques.

Routine scale and polish for periodontal health in adults.

Background: Many dentists or hygienists provide scaling and polishing for patients at regular intervals, even for those at low risk of developing periodontal disease. There is debate over the clinical and cost effectiveness of 'routine scaling and polishing' and the optimal frequency at which it should be provided for healthy adults.A 'routine scale and polish' treatment is defined as scaling or polishing, or both, of the crown and root surfaces of teeth to remove local irritational factors (plaque, calculus, debris and staining), which does not involve periodontal surgery or any form of adjunctive periodontal therapy such as the use of chemotherapeutic agents or root planing.

One-to-one oral hygiene advice provided in a dental setting for oral health.

Background: Effective oral hygiene measures carried out on a regular basis are vital to maintain good oral health. One-to-one oral hygiene advice (OHA) within the dental setting is often provided as a means to motivate individuals and to help achieve improved levels of oral health. However, it is unclear if one-to-one OHA in a dental setting is effective in improving oral health and what method(s) might be most effective and efficient.

Improving the Quality of Dentistry (IQuaD): a cluster factorial randomised controlled trial comparing the effectiveness and cost-benefit of oral hygiene advice and/or periodontal instrumentation with routine care for the prevention and management of periodontal disease in dentate adults attending dental primary care.

Background: Periodontal disease is preventable but remains the most common oral disease worldwide, with major health and economic implications. Stakeholders lack reliable evidence of the relative clinical effectiveness and cost-effectiveness of different types of oral hygiene advice (OHA) and the optimal frequency of periodontal instrumentation (PI).

Objectives: To test clinical effectiveness and assess the economic value of the following strategies: personalised OHA versus routine OHA, 12-monthly PI (scale and polish) compared with 6-monthly PI, and no PI compared with 6-monthly PI.
