ABSTRACT
BACKGROUND: Dental caries remains a significant problem in England, affecting 11% of 3-year-olds and 23% of 5-year-olds. While current approaches have been extensively investigated, their ability to (1) control pain and infection; (2) prevent hospital admissions, and (3) be implemented within the National Health Service (NHS) contractual arrangements, remains unsatisfactory. Silver diamine fluoride (SDF) is an alternative, non-invasive approach that has proven efficacy in arresting caries progression in primary teeth, principally from studies conducted outside of Europe. Its use in primary dental care in the UK is limited, despite the acknowledged need. The clinical and cost-effectiveness of SDF has not been compared to usual care in the UK. Before a pragmatic randomised controlled trial (RCT) can be conducted to compare SDF to usual care for caries management in young children, there are several uncertainties that require investigation. This study aims to establish whether such an RCT is feasible. METHODS: This mixed-method parallel design study is a feasibility study with an embedded process evaluation, to compare SDF with usual treatment in primary dental care in the UK. It will be individually randomised, with 13 dentists and therapists, in 8 different dental primary care sites with a sample size of 80 child participants aged 1-8 years old. The aim will be to recruit ten participants per site with equal arm allocation. Follow-up will be for 1 year. The study will inform whether an RCT is feasible by resolving several key uncertainties. The acceptability and implementation of SDF and the research processes will be explored. Patient and Public Involvement and Engagement representatives will be involved throughout recruitment and retention strategies, participant documentation, analysis, engagement and dissemination. DISCUSSION: The ability to conduct an RCT will be evaluated. If feasible, this RCT has the potential to evaluate the effectiveness of a non-invasive approach for the management of untreated caries in young children. A feasibility study also offers the opportunity to consider factors associated with the implementation of SDF at an early stage through a process evaluation that will inform the definitive trial and an implementation strategy for SDF by identifying relevant barriers and facilitators.

ABSTRACT
INTRODUCTION: Cariogenic bacterial acids dissolve the inorganic elements in dentine, leaving the dentine matrix exposed. Host-derived matrix metalloproteinases (MMPs) play an essential role in caries progression as they are significant regulators of extracellular matrix turnover and can degrade exposed collagen. This paper investigates the expression of MMP2 and MMP9 across various stages of caries in primary human teeth and relate this with a diagnosis recorded by the International Caries Detection and Assessment System (ICDAS). METHODS: Twenty-four sections (150 µm in thickness) from extracted teeth, clinically diagnosed using ICDAS, were immunohistochemically treated with monoclonal anti-MMP2 and anti-MMP9 antibodies. Positive staining was visualised by immunofluorescence using a VectorFluor Duet Double Labeling Kit. Images from triplicate samples for each ICDAS score were analysed using ImageJ software. Collagen degradation in caries lesions was detected using a hydroxyproline assay. RESULTS: MMPs were weakly detected in caries with ICDAS 1-2 scores, and an insignificant increase was detected in ICDAS 3. However, a significant increase in MMP expression was seen in caries with an ICDAS score of 4-6. There was a strong positive correlation between the ICDAS score and MMP2 (r [6] = 0.86, p = 0.002) and between ICDAS and MMP9 (r [6] = 0.82, p = 0.004). Data were analysed using two-way ANOVA followed by Tukey multiple comparison test (*p < 0.05). CONCLUSION: The use of ICDAS to assess the severity of caries lesions and how this correlates with the presence of MMP in these lesions validates the modern approach to caries management with a minimally invasive concept.
ABSTRACT
DESIGN: Narrative review. REVIEW QUESTION: What are the implications of new nicotine and tobacco products on adolescent health? PRODUCTS: E-cigarettes and oral nicotine products such as pouches, lozenges, tablets, gum, and gummies. RESULTS: These products can be addictive and can cause respiratory, cardiovascular and oral potential health problems. They also have effects on brain development. Products are attractive to adolescents, with more than 1:10 American adolescents uses them. CONCLUSIONS: The use of nicotine and tobacco products by adolescents puts their health at risk and may, in some instances, lead to nicotine addiction. Those providing healthcare for adolescents have an opportunity to provide advice and signpost people to resources to help them stop using such products. There is also a need for legislation to restrict the sale of e-cigarettes and tobacco products.

Introduction Caries in the primary dentition affects around one-quarter of children in England. There is uncertainty and varying practice regarding the management of these children within NHS primary dental care. Silver diamine fluoride (SDF) is an approach that is not well-adopted nationally. This study aims to explore the factors affecting treatment choices for caries management in young children within primary dental care, including the use of SDF.Methods Semi-structured interviews were carried out via video conferencing with general dental practitioners and therapists working in NHS primary care. The topic guide covered factors which influence the management of caries in primary teeth, with SDF-specific questions. These were transcribed verbatim and analysed using thematic analysis.Results A total of 13 interviews were conducted with dental professionals working across Yorkshire and the East Midlands. Decision-making for caries management was dependent on inter-related factors, which also influenced SDF use. Treatment decisions were taken on a case-by-case basis, but were influenced by the child, their parents, the dental professional and service factors, along with the clinical technique.Conclusion Many individual- and system-level factors influence treatment decisions for early childhood caries. However, issues relating to remuneration and governance appear to be specific barriers to adoption of SDF in primary dental care.
ABSTRACT
Introduction The use of silver diamine fluoride (SDF) is relatively new to the UK. It is unknown how it is being used and for what indications in UK paediatric dental services.Aim To: 1) establish how SDF is being used across different paediatric dental settings in the UK; and 2) consider parental and patient views on the treatment experience and side effect of discolouration.Method A multi-site service evaluation was carried out across six paediatric dentistry units covering hospital and community services. Data were collected prospectively from 17/02/2020 to 02/03/2022. Simple descriptive statistics were used to analyse the data.Results Data were collected for 54 patients. The included patients had an age range of 2-13 years, with a mean of 4.9 years. The reason SDF was chosen was reported as: to avoid general anaesthetic (n = 25); to avoid extractions (n = 8); stabilisation (n = 25); acclimatisation (n = 24); and insufficient cooperation for other treatment (n = 17). In total, 42 cases had SDF applied to the primary dentition. This was in the anterior dentition for 18 patients and the posterior dentition for 15, with nine patients having SDF applied both anteriorly and posteriorly. The majority of children and parents were accepting of the technique and immediate aesthetic outcome.Conclusion In the services involved in this multi-site service evaluation, SDF is used for young patients in the primary dentition for the purpose of caries arrest. The technique was viewed positively by the majority of parents and children.

DESIGN: Systematic review. REVIEW QUESTION: Does splinting of traumatised primary teeth improve clinical outcomes? CASE SELECTION: Clinical studies published after 2003 reporting trauma (luxation, root fracture or alveolar fracture) to primary teeth, with a minimum follow-up of 6 months, were eligible for inclusion. Case reports were excluded, but case series were included. Studies reporting the outcome of splinting following avulsion injuries were excluded, as current guidance does not recommend re-implantation of teeth for these injuries. DATA ANALYSIS: Two researchers independently assessed the risk of bias in the included studies, with a third researcher resolving any disagreements. The same two independent researchers conducted a quality assessment of the included studies. RESULTS: Three retrospective studies met the inclusion criteria. Only one of these studies had a control group. High success rates were reported for the management of teeth with root fractures. A benefit for splinting teeth with lateral luxation was not identified. No alveolar fractures were included. CONCLUSIONS: This review suggests that the outcome of the management of root fractures in primary teeth may benefit from flexible splinting. However, the evidence base is low.

DESIGN: Investigator blind randomised controlled trial. INTERVENTION: One hundred and forty-five parents or carers of children up to four years of age were recruited from families attending a clinic for premature children in Brazil. The aim was to assess the influence of Oral Health Literacy (OHL/OHL-AQ) on the effective and safe use of fluoride toothpaste. The participants were stratified into adequate (12-17) and marginal/inadequate OHL (0-11) and randomly allocated into one of four intervention groups as follows, based on how information was provided: 1. written, 2. oral, 3. written & photograph, 4. oral & photograph. Socioeconomic status was also recorded. Prior to the intervention, the participant's ability to apply the correct amount of toothpaste (1000 p.p.m F-) was assessed. DATA ANALYSIS: Data were analysed using the t-test and one-way ANOVA. The chi-squared test was used to evaluate associations between participants' ability to select the correct toothpaste, sociodemographic characteristics, oral health habits and OHL. RESULTS: The majority of the sample were female (89%), with the whole sample's mean age being 31.9 ± 8.3 years. The OHL-AQ score ranged from 2-16 (mean: 11.3 ± 3.0). Before or after the intervention, having a higher level of OHL was associated with a tendency to deliver the more correct amount of toothpaste onto the brush. The interventions did lead to an improvement in the volume of toothpaste used across all groups. Only schooling was associated with the correct choice of toothpaste. CONCLUSIONS: Parents or guardians with higher OHL used less, and consequently more ideal amounts of, fluoride toothpaste for children compared to those with a lower level of OHL. This was the case both before and after the educational interventions. The allocation to intervention group did not predict the amount of toothpaste used. Finally, only schooling predicted the choice of correct fluoride toothpaste.

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. However, root canal treatment involving complete removal of the pulp is often the only option (other than extraction) given to patients with irreversible pulpitis, with substantial NHS and patient incurred costs. The European Society of Endodontology's (ESE 2019) recent consensus statement recommends full pulpotomy, where the inflamed coronal pulp is removed with the goal of keeping the radicular pulp vital, as a more minimally invasive technique, potentially avoiding complex root canal treatment. Although this technique may be provided in secondary care, it has not been routinely implemented or evaluated in UK General Dental Practice. METHOD: This feasibility study aims to identify and assess in a primary care setting the training needs of general dental practitioners and clinical fidelity of the full pulpotomy intervention, estimate likely eligible patient pool and develop recruitment materials ahead of the main randomised controlled trial comparing the clinical and cost-effectiveness of full pulpotomy compared to root canal treatment in pre/molar teeth of adults 16 years and older showing signs indicative of irreversible pulpitis. The feasibility study will recruit and train 10 primary care dentists in the full pulpotomy technique. Dentists will recruit and provide full pulpotomy to 40 participants (four per practice) with indications of partial irreversible pulpitis. DISCUSSION: The Pulpotomy for the Management of Irreversible Pulpitis in Mature Teeth (PIP) study will address the lack of high-quality evidence in the treatment of irreversible pulpitis, to aid dental practitioners, patients and policymakers in their decision-making. The PIP feasibility study will inform the main study on the practicality of providing both training and provision of the full pulpotomy technique in general dental practice.

ABSTRACT
Background Dental caries in children's permanent teeth remains a global burden. In contrast to the traditional approach of treating the disease through surgical operative intervention, minimum intervention has increasingly been recommended for managing children with dental caries.Aim This scoping review aimed to describe the literature related to the provision of minimum intervention dentistry for children with caries and to identify research gaps.Methods Electronic databases (Medline via Ovid, PubMed, Web of Science and Scopus) were searched, together with grey literature databases, and key organisation websites. Data was extracted on a piloted extraction template and a thematic analysis was undertaken.Results Sixty-seven relevant articles were identified. No empirical literature was identified that assessed a complete minimum intervention care pathway to managing caries. Five themes were identified from the scoping literature: evidence base, clinician attitude and skills, practice implementation, acceptability and environmental factors.Conclusions The majority of articles were opinion papers. There is a paucity of empirical evidence supporting the clinical and cost-effectiveness of a minimum intervention pathway for children with dental caries in primary dental care. The scoping review has identified some potential barriers to the implementation of such a care pathway, including regulatory and remunerative frameworks and clinical training/education.
ABSTRACT
BACKGROUND: Melatonin's effectiveness as an anxiolytic medication has been confirmed in adults; however, its efficacy in a paediatric population is unclear. A number of small studies have assessed its use in children as a pre-operative anxiolytic, with conflicting results. METHODS: We undertook a systematic review of pre-operative melatonin use in children. Four databases (MEDLINE, Embase, the Cochrane Central Register of Controlled Trials and Web of Science), and ' ClinicalTrials.gov ' were searched for ongoing and completed clinical trials of relevance. Citation tracking reference lists and relevant articles were also accessed. The review was unrestricted by comparator or outcomes. Eleven studies were judged eligible for inclusion. There were high levels of heterogeneity in melatonin administration (in terms of dose and timing). Variable outcomes were reported and included: anxiety; anaesthetic success; analgesia; sedation; post-operative recovery; and safety. Outcomes were not always assessed with the same measures. RESULTS: Evidence to support melatonin's anxiolytic properties in this setting is conflicting. Melatonin was associated with reduced sedative effects, post-operative excitement and improved emergence behaviour, compared to comparator drugs. One study reported the benefit of melatonin use on sleep disturbance at two weeks post-surgery. No adverse safety events were identified to be significantly associated with melatonin, affirming its excellent safety profile. CONCLUSION: Despite potential advantages, including improved emergence behaviour, based on current evidence we cannot confirm whether melatonin is non-inferior to current "usual care" pre-medications. Further consideration of melatonin as an anxiolytic pre-medication in paediatric surgery is needed.

Aim The aim of this study was to establish the diagnostic efficacy of panoramic radiographs in six clinical situations for paediatric patients: caries, acute dental infections, dental trauma, dental anomalies, developmental disorders and pathological conditions.Data sources The authors searched the following databases: Medline, Embase, the Cochrane Oral Health Group's Trials Register, the Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews, the Database of Abstracts of Reviews of Effects and the Cochrane Health Technology Assessment database. Forward citation searches of included studies were carried out. There were no language restrictions. The dates were restricted to include studies published between 1990-2018.Study selection Inclusion criteria: children under the age of 18 for whom the diagnostic accuracy of panoramic radiography was compared to either clinical or an alternative radiographic examination for the six included indications. Exclusion criteria: panoramic radiographs taken for orthodontic indications outwith those stated in the aim. Studies of all designs were included. Screening of titles, abstracts and full texts were completed independently and in duplicate by two authors. Disagreement was resolved by discussion including a third author. A total of 3,420 abstracts were screened, from which 175 full texts were reviewed. Sixteen studies across the six indications were included in the review.Data extraction and synthesis Data extraction was performed independently and in duplicate by two authors, with a third resolving disagreement. A standardised form was used which was initially piloted on ten papers. A narrative synthesis was carried out due to heterogeneity of the included studies precluding data synthesis.Results Assessment of bias was completed using the QUADAS 2 tool. Of 16 included studies, the majority were of high or unclear risk of bias for domains including: patient selection, conduct or interpretation of the index test, reference standard, and patient timing and flow. Regarding detection of caries, one study was included which demonstrated clinical examination detected more carious surfaces than panoramic radiographs (6.0%, 95% CI 4.1-7.8%), but that bitewing radiography combined with panoramic radiography led to a higher diagnosis of approximal lesions than clinical examination alone by 4.3% (p <0.0001). Concerning acute dental infection, one study was included that did not present diagnostic accuracy data. Three studies related to dental trauma were included, all of which examined condylar fractures. Only one study reported diagnostic accuracy data: 70% diagnostic accuracy with panoramic radiography compared to 92% utilising CT scans. Four studies included examined diagnosis of a spectrum of dental anomalies. The only study to provide data on diagnostic accuracy reported a sensitivity of 50% for correct identification of supernumerary teeth on panoramic radiographs, with a specificity of 97.2%. Five included studies pertained to developmental disorders. One study gave data on diagnostic accuracy of panoramic radiographs. This showed sensitivity of 68.2% for identification of abnormalities in familial adenomatous polyposis. Two studies included were related to pathological conditions - one reported that panoramic radiographs gave 75% sensitivity to identify abnormal condylar morphology in patients with TMJ synovitis, with a specificity of 66.7%.Conclusions The study concluded that more research is required concerning the diagnostic accuracy of panoramic radiographs for oral conditions in order to produce clinical guidance based on high-quality evidence.

There is a requirement to ensure that in vitro studies that use demineralized human dentine models are reliable and clinically relevant. The literature reports several strategies for these studies with a lack of consensus on the mode of action of the different demineralizing acids on human dentine. This in vitro study aims to characterize the effect of clinically relevant acids on human dentine, using standardized substrates and complementary analytical techniques. The study focuses on an analysis of the mineral content and the integrity of the collagen following partial demineralization. Samples of human dentine were exposed to a range of acids commonly encountered in the oral cavity. Characterization of the mineral content used Vickers micro-hardness, energy-dispersive spectroscopy, and X-ray fluorescence. Characterization of the collagen integrity was undertaken by means of scanning electron microscopy and hydroxyproline assay. The following conclusions were reached: (i) each demineralizing agent tested had a unique effect on the mineral levels; (ii) chelating agents, strong acids, and weak acids affect the mineral and organic phases of dentine in significantly different ways with no correlation between them; and (iii) the demineralizing agents caused some degree of collagen denaturation, citric acid causing the most damage. Overall, there is no clear link between the type of demineralizing agent and the effect on the organic and inorganic dentine. The choice of demineralizing agent should be aligned to the experiment objectives so that the selected dentine (caries or erosion) model is fit for the purpose.

BACKGROUND: The 'Melatonin for Anxiety prior to General anaesthesia In Children' (MAGIC) trial was designed to compare midazolam and melatonin as pre-medications for anxious children (aged five to fourteen), undergoing day-case surgical procedures under general anaesthesia. Low recruitment is a challenge for many trials, particularly paediatric trials and those in 'emergency' settings. A qualitative study as part of MAGIC aimed to gather stakeholder perspectives on barriers and enablers to recruitment. METHODS: Sixteen stakeholders from six sites participated in semi-structured interviews about their experiences of setting up the MAGIC trial and recruiting patients as part of the internal pilot. Data was analysed using framework analysis. RESULTS: Participants identified barriers and enablers to recruitment. Barriers and enablers related to the study, participants, the population of anxious children, practitioners, collaboration with other health professionals, ethics, specific settings and the context of surgical day units and the wider health system. Attempting to recruit anxious children from a surgical day unit is particularly challenging for several reasons. Issues include the practicalities of dealing with a child experiencing anxiety for parents/guardians; professional unwillingness to make things more difficult for families and clinicians and nurses valuing predictability within a busy and time-sensitive setting. CONCLUSIONS: Multi-site RCTs face recruitment barriers relating to study-wide and site-specific factors. There are multiple barriers to recruiting anxious children due to undergo day-case surgery. Barriers across domains can interrelate and reinforce each other, reflecting challenges relating to populations and settings. For example, in the case of anxious children, parents and other health professionals are concerned about exacerbating children's anxiety prior to surgery. They may look for ways to keep things predictable and avoid the uncertainty of an RCT. Pre-trial engagement work could help address concerns among collaborating health professionals. Using rapid ethnography during set-up or an internal pilot to focus on how the protocol will be or has been operationalised in practice may help identify issues. Allowing time to reflect on the findings of internal pilots and implement necessary changes could facilitate higher recruitment during the main phase of a trial.

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. However, despite its prevalence there is no consensus on how much caries to remove prior to placing a restoration to achieve optimal outcomes. Evidence for selective compared to complete or near-complete caries removal suggests there may be benefits for selective removal in sustaining tooth vitality, therefore avoiding abscess formation and pain, so eliminating the need for more complex and costly treatment or eventual tooth loss. However, the evidence is of low scientific quality and mainly gleaned from studies in primary teeth. METHOD: This is a pragmatic, multi-centre, two-arm patient randomised controlled clinical trial including an internal pilot set in primary dental care in Scotland and England. Dental health professionals will recruit 623 participants over 12-years of age with deep carious lesions in their permanent posterior teeth. Participants will have a single tooth randomised to either the selective caries removal or complete caries removal treatment arm. Baseline measures and outcome data (during the 3-year follow-up period) will be assessed through clinical examination, patient questionnaires and NHS databases. A mixed-method process evaluation will complement the clinical and economic outcome evaluation and examine implementation, mechanisms of impact and context. The primary outcome at three years is sustained tooth vitality. The primary economic outcome is net benefit modelled over a lifetime horizon. Clinical secondary outcomes include pulp exposure, progession of caries, restoration failure; as well as patient-centred and economic outcomes. DISCUSSION: SCRiPT will provide evidence for the most clinically effective and cost-beneficial approach to managing deep carious lesions in permanent posterior teeth in primary care. This will support general dental practitioners, patients and policy makers in decision making. Trial Registration Trial registry: ISRCTN. TRIAL REGISTRATION NUMBER: ISRCTN76503940.

Aim To provide an international perspective on COVID-19 (SARS-CoV-2) safety measures and discuss the medico-legal perspective of providing dental care during the COVID-19 pandemic.Data sources This paper is a narrative review. The authors are drawn from academic dentistry and academic law.COVID-19 safety measures in dental clinics Dental care professionals are considered to be at high risk of exposure and subsequent transmission of COVID-19. Therefore, it is of great importance that dental professions put in place measures to prevent cross infection from the virus. These measures include screening patients and spacing of appointments to allow fallow time. Within the clinic, there is a requirement for adequate ventilation (perhaps aided by air cleaners and disinfection air fogging devices) together with cleaning and use of alcohol gels to ensure hands are clean. With regards to dental treatment, the measures expected are also itemised, such as the use of virucidal antiseptic mouthwash, use of personal protective equipment, rubber dam and moving to non-aerosol generating procedures wherever possible.COVID-19 safety measures and the law The point is made that the need for the implementation of these precautions is not only necessary for cross-infection prevention but also for the avoidance of legal issues. The paper discusses the liability of a dentist, both criminal and civil, should a person contract COVID-19 as a result of attending for dental treatment. Although opinion varies across legal jurisdictions, the general consensus is that a practitioner would only be liable if they had been negligent. This is not just the case when guidelines are available, whether legally enforced or not, as the practitioner is required to deliver care in an up-to-date and evidence-based manner. There is a need to document persuasions taken to protect the practitioner from litigation.Conclusion Dentists should follow the scientific evidence to reduce as much as possible the risk of them contracting or spreading COVID-19. In addition, to avoid criminal or civil legal consequences, all procedures to avoid cross infection should be documented, as in not doing so, the practitioner will not be able to prove they were carried out.

Aim This systematic review and meta-analysis of randomised controlled trials (RCTs) aimed to compare the efficacy of different caries removal techniques: complete caries removal (CCR), selective caries removal (SCR) and stepwise caries removal (SWR) for deep carious lesions in vital primary teeth.Data sources The design of this review followed the PRISMA guidance ( http://www.prisma-statement.org/ ). Relevant studies were identified using electronic databases (PubMed [Medline], Cochrane Library, EMBASE) and finally reference lists were screened. The US National Institutes of Health Trials Register (NIHTR; http://clinicaltrials.gov ) and World Health Organisation International Clinical Trials Registry Platform (WHO ICTRP; http://apps.who.int/trialsearch ) were used to help assess publication bias, as it was not possible to test funnel plot asymmetry. Duplicates were located and eliminated using EndNote X7 programme.Study selection To be included, studies had to be published RCTs comparing SCR or SWR with CCR as caries removal strategies for deep carious lesions in vital primary teeth. The outcomes were pulp exposure, pulpo-periodontal complications (clinical and radiological failures) and/or restorative failures. RCTs applying these caries removal techniques were excluded if one of the other trial arms did not involve caries removal (that is, Hall Technique, therapeutic sealing of cavity lesions). Initially, 1,374 potentially eligible articles were identified, out of which 15 (English or French language only) were selected for full-text screening, which included ten relevant references corresponding to eight studies.Data extraction and synthesis Two authors independently extracted data using a piloted data extraction sheet, with a third reviewer resolving any disagreements. The authors performed conventional intention-to-treat and per-protocol meta-analyses, and calculated odds ratios (ORs) as effect estimates in the random-effects model, using Revman5.Results The eight included RCTs were conducted between 1977 and 2018. They include 669 patients and 824 teeth, with follow-up ranging from four weeks to 24 months. Collective results showed reduced risk of pulp exposure after SCR (OR: 0.10, 95% CI [0.04, 0.25]) or SWR (OR: 0.20, 95% CI [0.09, 0.44]), compared with CCR. There was a higher risk of composite restorative failure (OR: 2.61, 95% CI [1.05, 6.49]) using United States Public Health Service (USPHS) criteria, after SCR was compared with CCR only in intention-to-treat analysis. However, when comparing the risk of clinical or radiographic failure of pulpo-periodontal complications, no difference was found between SCR, CCR or SWR.Conclusion The conclusions of the paper are that there is a significant decrease in pulp exposure risk with SCR and SWR in comparison with CCR. However, there is a need for further studies with less risk of bias powered to report on the long-term outcomes of pulpo-periodontal health and restoration longevity.

Study selection Medline via PubMed and Embase were searched on 6 November 2019 and all studies up to this date were included, including case reports and case series. This was noted as being due to the limited number of studies available in this research area. The outcome measured was clinical success, which was defined as the tooth being present and an assumption that it was sound and asymptomatic at the end of the study. Studies that did not include a minimum of six months' follow-up were excluded, as were editorial letters, in vitro studies and studies not reported in English.Data extraction and synthesis One reviewer searched databases for appropriate studies, then a second reviewer assisted in assessing studies by title and abstract. For each eligible article the operator, sample size, and a full dental diagnosis were recorded. Treatment method, follow-up and treatment success were also assessed.Results The systematic review included eleven studies. The GRADE approach was used to assess quality of evidence. Three studies were of high quality, six of low quality, and two of very low quality. Cochrane and Robins-I risk tools were used to assess bias. All randomised controlled trials were assessed to be of high risk of bias, due to the blinding process not being stated. Six non-randomised controlled trials were assessed to be of critical risk of bias, as the measurement of treatment outcomes was not stated. There was a high risk of bias determined overall.The review reported a 90.5% (range 70-100%) success rate over a mean follow-up period of 28.4 months (range 6-73.6 months) for coronal pulpotomies, which is in line with the results from adult studies. For partial pulpotomies the review reported a 91.3% (range 78.5-100%) success rate over a mean follow-up period of 34.4 months (range 12-140 months), which is slightly lower than reported in adult studies.Only one study on conventional pulpectomies was included in the review that reported a success rate of 36% for a small sample of patients (n = 10).No studies on apexification of molar teeth were included in the review. Therefore, further evidence is required to assess the success of this therapy.One case report showed success with regenerative endodontics for a single molar. Therefore, significant further evidence will be required to assess this approach.Conclusion The systematic review ascertained that partial and coronal pulpotomies had successful treatment outcomes for treating compromised first permanent molar teeth.

Objective To evaluate the effectiveness of school dental screening in improving oral health status and the use of dental services. This review is an update of the original review published in 2017. As you would expect of a Cochrane review, the methodology was of high quality.Study selection Inclusion criteria: randomised controlled trails (RCTs) that evaluated school dental screening compared with no intervention or with another type of screening. The outcome of six of the trials presented dental attendance as the main outcome, while one trail (Nelson 2019) measured the main outcome as receipt of dental care. The studies had an average follow-up period of three to four months, with none reporting on the long term. A total of 3,093 records were identified in the initial search. Twenty-seven full-text copies were requested, and 17 reports and one ongoing study were excluded. Seven studies met the inclusion criteria (reported in nine articles).Results The systematic review included seven trials (four from the UK, two from India and one from the USA) involving 20,192 children aged 4-15 years. Based on the Cochrane risk of bias tool, two trials were determined to be at low risk of bias, two trials were high risk of bias and three trials were assessed to be at unclear risk of bias. Due to the inconsistency in evidence, the review was unable to draw conclusions between traditional screening versus no screening. The comparison between criteria-based screening versus no screening was evaluated, showing a pooled effect estimate of RR 1.07 (95% CI 0.99 to 1.16), which suggested a possible benefit for screening. Criteria-based screening was compared to traditional screening (RR 1.01, 95% CI 0.94 to 1.08), with no evidence of a difference in effectiveness. No trials reported on the potential adverse effects of school dental screening programmes.Conclusion The systematic review found there was very low certainty of evidence to support the role of school screening programmes in improving dental attendance. There was a low certainty of evidence to conclude that criteria-based screening, personalised referral letters or screening supplemented with motivation improve dental attendance.

Aim This narrative review aims to report on the impacts of COVID-19 on the provision of dental education in the 67 dental schools in the United States (US). Having set the scene and current challenges, it aims to suggest some strategies to overcome the issues facing dental schools going forward.Background In the US the Occupational Safety and Health Administration classified dentists in the very high risk category because of the potential for exposure to the virus as a result of aerosol generating procedures (AGP). In the last 20 years there have been two previous outbreaks of coronaviruses (severe acute respiratory syndrome and Middle East respiratory syndrome) which resulted in no long-term changes in the provision of dental education. The recent paper from Wuhan, China described action in the height of the infection but no sustainable actions to deliver dental education going forward.Challenges The challenges identified include: protecting the health of students, faculty and staff; ensuring the continuity and quality of dental education; ensuring confidence in health and safety measures; and keeping up with guidance. There is some variation across the US but most schools have suspended clinical teaching and implemented stay at home policies. Others have implemented social distancing in laboratories including clinical skills. The final challenge is ensuring that students have the teaching, experience and are assessed to ensure the competency of the graduating student.Solutions Technology in teaching and learning offers many opportunities. For didactic teaching distance learning has been implemented. There are 'off the shelf' programmes for teaching and assessment. The development of bespoke content is time consuming and one solution is for schools to share material. Although still requiring social distancing, manikins and haptics offer some opportunities for skills training. The need for excellent information sharing with faculty and students is emphasised.Conclusion Schools should re-evaluate their policies and curricula and incorporate appropriate methods of distance learning permanently into their teaching. Students should have outreach and multi-professional support in order to allow them to assist in the community during public health crises. Finally, gaps have been identified in US dental schools preparedness for pandemics.
