Dental treatment approaches of amelogenesis imperfecta in children and young adults: A systematic review of the literature

OBJECTIVE

The aim of this review was to compare various types of restorations used in children and young adults affected with amelogenesis imperfecta (AI) to determine the most effective restorative treatment.

METHODS

This systematic review included randomized controlled trials, retrospective and prospective cohorts conducted on children and young adults diagnosed with amelogenesis imperfecta and written in French or English. A systematic search was conducted using four databases, namely Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE via PubMed, Science Direct and Scopus, using a selection of MeSH terms: "Amelogenesis Imperfecta," "Therapeutics," "Treatment Outcome," "Adult, young," "Child," "Dental Restoration, Permanent," "Dental Restoration, Temporary," and "Esthetics, Dental."

RESULTS

Out of 138 articles identified in the initial search, four articles met all the inclusion criteria. The results showed that ceramic restorations had better quality scores and longevity compared to other restorations.

CONCLUSION

Ceramic restorations could be considered the restorative treatment modality of choice for AI-affected children and young adults. However, more high-quality clinical trials involving young patients affected with AI are required to evaluate and compare the outcomes of different restorative approaches.

CLINICAL SIGNIFICANCE

Young patients affected with amelogenesis imperfecta usually suffer from low self-esteem, psychological problems and social avoidance, caused by the alteration of teeth such as discoloration, sensitivity, fractures and reduced size. For the dentist, selecting the appropriate restorative treatment for AI in young patients could be a veritable challenge. Therefore, it is important to have an evidence-based modality. For this reason, in this review, the different restorative approaches used in AI-affected young patients were compared to recommend the most effective treatment.

Public health policies in dental traumatology: A call for action!

Traumatic dental injuries (TDI) are a prevalent public health concern, requiring preventive measures as well as timely and appropriate interventions to prevent adverse outcomes and optimize patients' prognosis. Although dental trauma injuries require prompt clinical intervention, some challenges persist in effectively managing these injuries. In dental traumatology, the implementation of public health policies assumes critical importance, these policies play an important role in addressing preventive measures and mitigating the repercussions of TDI. This review aims to emphasize the importance of developing comprehensive public health policies in dental traumatology, recognizing the strategic importance of this approach and its benefits. By proactively addressing issues associated with dental injuries, these policies have extensive implications for individual quality of life and public health in general. Furthermore, this review will present a suggested structured framework for the development of public health policies, encompassing key domains including prevention, intervention, and education in dental traumatology. The creation and implementation of these policies will address dental trauma through prevention programs, research, and development, and will provide a significant step toward enhancing the well-being of the population and dental trauma victims' prognosis promoting a more resilient healthcare system.

Unusual approach to treat malocclusion with traumatically missing and hopeless maxillary unilateral incisors: A case report

Orthodontic cases requiring tooth extraction sometimes involve post-traumatic incisors. For adolescent cases in which trauma causes the maxillary unilateral incisors to be missing or have poor prognoses, it is worth considering these teeth as candidates for extraction, and this unusual approach is seldom reported in the literature. An adolescent patient with a missing maxillary left lateral incisor and an ankylosed maxillary left central incisor sought treatment for dental protrusion and crowding. An unusual orthodontic approach was used, which involved the extraction of the maxillary left central incisor and mandibular first premolars. After treatment, the maxillary right central incisor was successfully translocated across the midpalatal suture and transformed into the left central incisor. Additionally, well-aligned teeth and enhanced smile aesthetics were achieved, and the treatment outcomes remained stable throughout the follow-up period.

What is important to medical students' online learning of dental trauma in medical education

Traumatic dental injury (TDI), a topic not normally offered in the medical curriculum is made available through the medical school as an online learning course. Online learning provides an educational pathway for cross-disciplinary learning without any change to the existing curriculum. This research identified important key features that should be included in the design of an online course to provide a positive online learning experience for medical students. Ten important features were identified for medical educators to consider when they develop an online course to introduce dental trauma. These features are (1) prioritising information to TDI, (2) providing specific facts and information to TDI, (3) information must be easily retrieved, (4) providing career-related information, (5) promoting self-confidence, (6) promoting learning of new knowledge, (7) easy-to-understand content materials, (8) establishing a logical sequence of learning, (9) visual illustrations to complement written text and (10) promoting self-directed learning.

Prevalence of traumatic dental injuries in emergency dental services: A systematic review and meta-analysis

OBJECTIVES

This study aimed to perform a systematic review and meta-analysis regarding the prevalence of traumatic dental injuries (TDI) in emergency dental services.

METHODS

Seven electronic and two grey literature databases were searched, up to December 2021, for studies that reported the TDI prevalence among dental emergencies. The Joanna Briggs Institute critical appraisal checklist for prevalence studies, and The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach were used to assess the risk of bias and quality of evidence respectively. The R software was used to perform a proportion meta-analysis on a random-effects model to estimate the pooled prevalence and respective 95% CI.

RESULTS

From a total of 1476 studies identified after excluding duplicates, 38 met the inclusion criteria, and another five were identified through hand searching, summing 43 included observational studies with a total sample of 209099 individuals searching for emergency dental care. The overall pooled prevalence of TDI was 15.4% (95% CI: 11%-21%, I² = 100%). Paediatric dental emergency services and age group from 0 to 21 years presented the highest prevalence, 29% (95% CI: 22%-38%, I² = 99.5%) and 24% (95% CI: 15%-35%, I² = 98%) respectively.

CONCLUSIONS

The overall pooled prevalence of TDI in emergency dental services was 15.4%, and 24% in the age group under 21 years. Considering the impact of prompt and correct emergency care in the long-term prognosis of TDI, such knowledge is relevant to organize emergency healthcare and support public policies in this area.

Splinting in the management of dental trauma in the primary dentition: a systematic review

PURPOSE

The purpose of this study was to gather existing data on the efficacy of tooth splinting (TS) in patients with traumatized primary teeth, evaluating their overall prognosis and reported complications.

METHODS

Electronic searches were performed in seven databases up to Februray/2023. Clinical studies published in the last two decades and presenting the following characteristics were included: (a) reporting on children with traumatized primary teeth; (b) describing the efficacy of splinting those teeth. Studies describing imobilization of dental avulsion were excluded.

RESULTS

A total of 163 potentially relevant studies were initially found. After title/abstract screening, and full-text evaluation, three retrospective studies with moderate to high risk of bias were included. The studies described the outcomes of TS in primary teeth with luxation (intrusion, extrusion, lateral displacement), intra-alveolar root fracture, and/or alveolar fracture. High clinical success rate was observed for teeth with root fracture. Benefits of spliting teeth with lateral luxation were not identified, although it may be a reccomended approach. No study was found evaluating TS for alveolar fracture.

CONCLUSION

Based on a low level of evidence, the findings highlight a better clinical success rate of the use of TS in the management of deciduous teeth with root fractures.

Dental undergraduate students' ability in the diagnosis of root fractures: Comparative analysis of different imaging methods

OBJECTIVE

The aim of this study was to evaluate the diagnostic ability of dental undergraduate students to detect horizontal and oblique root fractures (ORFs) using different imaging techniques.

MATERIALS AND METHODS

Nine teeth were selected and randomly divided in three groups in order to create a fracture line without fragments separation: control (without fracture), horizontal root fracture (HRF), and ORF. The root fracture was created using perpendicular force and was confirmed by transillumination. A model with two adjacent teeth was created, and different imaging techniques were performed: conventional periapical radiograph; mesially and distally shifted periapical radiographs; cone-beam computer tomography (CBCT). Twenty students that had participation on dental trauma clinic at the year of 2019 were invited to identify root fractures by a five-point scale: (i) fracture definitely not present, (ii) fracture probably not present, (iii) uncertain whether fracture is present or not, (iv) fracture probably present, and (v) fracture definitely present. Data were analyzed by Kappa test for agreement evaluation.

RESULTS

Comparing each student to the gold standard, there was a variation in reproducibility and performance from poor to substantial (0.042-0.667). Reproducibility values ranged from poor to good for all periapical radiographs both in the diagnosis of ORF (-0.33-0.667) and in HRF (0-1).

CONCLUSIONS

In CBCT images, the students' ability was lower in HRF detection in comparison with the oblique ones. The students showed limited capacity to diagnose root fractures; however when CBCT was used, the performance was more satisfactory than when periapical radiographs were used.

Developing a prototype dental trauma e-learning course for medical education

This article aims to demonstrate how an expert feedback process was used to identify emerging issues within a prototype extracurricular course on dental trauma and show how the feedback was addressed prior to piloting the course more widely. Dowse's Design Research Model was adapted for the design and development of a prototype dental trauma e-learning course. This paper will focus on step five, gathering expert feedback and the evaluation process. Four critical features emerged from the feedback that ought to be incorporated into the e-learning course design, namely, 1) keep resources clinically relevant; 2) keep resources simple to learn; 3) make resources easy to understand; and 4) support self-learning. The results demonstrate the value of an expert feedback process for improving a prototype designed to address a major gap in knowledge among medical doctors identified in the literature.

Introduction of an interactive tool (the Dental Trauma Guide) in the undergraduate dental teaching to manage traumatic dental injuries

BACKGROUND/AIMS

Traumatic dental injuries (TDI) are complex problems where lack of proper care may result in serious complications. The need to improve the management of TDI is a frequently addressed concern. Methods of improvement in their diagnosis and management are continuously evolving. The interactive Internet tool, the Dental Trauma Guide (DTG), helps to simplify diagnostic and management dilemmas. However, it is not a freely available tool. The aim of the current study was to assess the knowledge and diagnostic skills of undergraduate dental students with access to the DTG compared with students without such access, in order to validate and promote this tool in dental education.

MATERIALS AND METHODS

Two groups of students were randomly selected where one group of final year dental undergraduate students were exposed to lectures, demonstrations, discussions and tutorials on the management of TDI according to the standard undergraduate curriculum in Sri Lanka. Another test group of 21 students were provided with access to DTG during their training in paediatric dentistry. At the end of the study period, students were assessed on their knowledge of TDI using MCQs (Multiple Choice Questions) and OSCEs (Objective Structured Clinical Examination), based on the DTG.

RESULTS

The students with access to the DTG were more knowledgeable in providing the correct answers to three out of the seven OSCE questions. Evaluation based on the MCQs did not reveal a significant difference (p = .913). However, users of the DTG showed a statistically significant difference with better overall knowledge based on their answers (p = .028). Following this period of evaluation, all of the students were provided with access to the DTG to supplement their learning experience.

CONCLUSION

The Dental Trauma Guide is a useful supplementary tool for undergraduate students to arrive at a correct diagnosis and treatment plan for TDI.

Management of Dental Avulsion Injuries: A Survey of Dental Support Staff in Cairns, Australia

Background/Aim: The aim of this study was to assess the knowledge of dental support staff in providing appropriate first-aid advice regarding dental avulsion emergencies. Methods: This study was reported according to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines for cross-sectional studies. Dental support staff (includes dental assistants, administrative staff and other non-clinical staff) were contacted and data were collected from 50 private dental clinics across the Greater Cairns Area, Queensland, Australia. These data were collected through an online survey throughout 2020. Descriptive statistics and Pearson’s Chi-squared test was used to analyze the data and any associations between categorical outcomes. Results: This survey yielded a response rate of 34.1% with a margin of error of 10.3%. More than four-tenths of participants (42%) reported that they had received some form of dental avulsion management training previously. All but five participants (92%) denoted that they would immediately replant an avulsed permanent tooth. More than half of all participants would choose to rinse a soiled avulsed tooth with fresh milk (55%) and transport that tooth in fresh milk (65%) should they not be able to replant the tooth at the site. Almost nine in every ten participants (85%) expressed willingness to further their training in this area. Knowledge in replanting avulsed permanent teeth was found to be significantly impacted by gender, age, years of experience and participation in formal avulsion training. Male participants were found to be significantly more likely (p = 0.025) to replant a permanent avulsed tooth than their female counterparts. Participants who were 40 years of age and above were found to be significantly more likely to choose fresh milk to transport avulsed teeth (p = 0.0478). Older participants (p = 0.0021), alongside those who had greater years of experience (p = 0.0112) and those who had undertaken formal avulsion training (p = 0.0106) were all significantly more likely to express greater confidence in their ability to manage dental avulsion injuries. Participants who had previously received some form of education regarding avulsion injury management were also most likely to warrant further education and training in this area (p < 0.0001). Conclusion: This study demonstrated that dental support staff in the Greater Cairns Area seem to have a fair grasp of first-aid knowledge regarding the management of dental avulsion injuries. This result indicates that this knowledge has been picked up through years of experience, rather than a formal education. Despite this, one would expect people who work in the dental industry to be able to provide accurate and appropriate assistance during dental emergencies, hence, further training is warranted to ensure optimum patient outcomes.

A proposal to introduce dental trauma into medical education: An insight

THE PROBLEM

This proposal aims to tackle the common poor management of traumatic dental injury (TDI) by medical doctors and subsequent poor healthcare outcomes for patients. The literature reports that most medical doctors, in either private practice or hospital emergency departments, lack the knowledge, skills, and confidence needed to adequately assess and manage victims of TDI. This is due to little or no clinical dentistry and dental trauma education being included in their medical studies.

THE GAP IN THE LITERATURE

From a review of the literature, there is a clear lack of learning provision for medical students on the topic of dental anatomy and trauma. In addition, there appears to be no formal university theoretical and clinical training during medical school.

THE PRACTICAL IMPLICATIONS

The introduction of dental trauma into the medical curriculum will provide students with a better understanding of the importance of early management for better patient outcomes. Medical doctors competent in managing emergency dental trauma procedures will be able to provide a higher standard of care that could prevent potentially lifelong negative repercussions for the patient.

Traumatic Intrusion of a Maxillary Canine Tooth: 3 Cases

Of the six recognized types of tooth luxation injuries, intrusion generally carries the most guarded long-term prognosis due to the high risk of complications, including root resorption, ankylosis, marginal bone loss, and pulp canal obliteration or necrosis. The degree of traumatic intrusion and stage of root development affects the outcome and treatment planning. This report describes the clinical history, oral and radiographic examination findings, and rationale for surgical extraction in 2 dogs and 1 cat with traumatic intrusion of a maxillary canine tooth.

Traumatic Dentoalveolar and Maxillofacial Injuries in Cats: Overview of diagnosis and management

PRACTICAL RELEVANCE

Maxillofacial and traumatic dentoalveolar injuries can cause pain and inflammation, and reduce function of the mouth, impacting a cat's quality of life. Many traumatically induced feline fractures have been reported to involve the mandible or skull and, in cats with maxillofacial trauma, traumatic dentoalveolar injuries are particularly prevalent. Traumatic dentoalveolar injuries can also often be found in otherwise healthy cats.

CLINICAL CHALLENGES

Some traumatic dentoalveolar injuries require emergency treatment; timely recognition and managment is therefore important for achieving the optimal outcome. Multiple approaches exist for the management and repair of maxillofacial traumatic injuries. However, those for traumatic dentoalveolar injuries may be more limited.

AUDIENCE

This review is aimed at feline and general practitioners, as well as veterinarians with expertise in dentistry.

EVIDENCE BASE

The authors draw on their clinical experience and evidence from the literature, where appropriate, to produce an overview of foundation guidelines. It is hoped that this will serve as a stimulus for deeper consideration as to what constitutes 'best practice' principles for cats with traumatic dentoalveolar and maxillofacial injuries.

Multidisciplinary treatment options of tooth avulsion considering different therapy concepts

BACKGROUND

Avulsion of permanent front teeth is a rare accident, mostly affecting children between seven and nine years of age. Replanted and splinted, these teeth often develop inflammation, severe resorption or ankylosis affecting alveolar bone development and have to be extracted sooner or later.

OBJECTIVES

The purpose of this study was to evaluate different therapy concepts to create a structured concept for the treatment of avulsions.

RESULTS

Based on existing therapy concepts, a concept for different initial conditions (dry time, age, growth, tooth, hard and soft tissues) was developed and is presented here.

CONCLUSION

A great deal of research has been performed during recent years and guidelines for the management of avulsions have been published. With the help of this literature it is possible to identify the best treatment procedure for each tooth.

CLINICAL RELEVANCE

The prognosis of avulsed teeth can be improved by considering evidence-based therapy concepts. Resorption, ankylosis and tooth loss could be minimized.

Outcome of restorative treatment in young patients with amelogenesis imperfecta. a cross-sectional, retrospective study

OBJECTIVES

The longevity of dental restorations in patients with amelogenesis imperfecta (AI) is limited. The aim of this paper is to compare oral health and longevity of dental restorations in a group of young patients with AI compared to a control group.

METHODS

Patients included were 82 patients with AI, 40 boys and 42 girls, 6 to 25 years old (mean age 14.5±4.3 years) and a control group matched in age, gender and residential area. All patients received an examination recording dental caries, gingivitis, previous therapy, replaced restorations, tooth sensitivity, and number of dental visits. Patient dental records, extending from 6 to 10 years before the study, provided data on previous care.

RESULTS

Annual mean number of dental visits in the AI group was 2.9±1.7 compared to 1.9±1.2 in the control group (p<0.001). DMFS was 8.1±15.6 in the AI group compared to 1.0±2.0 in the control group (p<0.001). The longevity of dental restorations was significantly lower in the patients with AI, with 24.7±35.1% of the AI group requiring replacement of fillings during the observation period compared to 9.23±23.7% in the control group (p=0.001). Patients with hypomineralized/hypomaturized AI have restorations of shorter longevity than those with hypoplastic AI (p<0.01). Porcelain crowns had significantly longer survival than composite resin materials in the AI group (p<0.001). Clinical Significance This study shows the need for long-lasting restorative solutions for patients with AI. It also shows the importance of establishing an early permanent therapy plan for these patients to avoid frequent dental visits.

Periodontal ligament strain induced by different orthodontic bracket removal techniques: nonlinear finite-element comparison study

OBJECTIVES

The goal of this work was to biomechanically analyze several different methods of bracket debonding and compare the strain they induce in the periodontal ligament (PDL).

METHODS

The CT dataset of an anatomical specimen was divided into four segmental models of the mandible. Each model covered one tooth (32, 42, 44, and 47). One of these teeth (32) was characterized by marked loss of periodontal attachment. After suitable finite-element models were generated, material properties were defined as nonlinear for PDL and anisotropic for the alveolar bone. This was followed by simulating four bracket debonding techniques: frontal and lateral torquing, bracket-wing compression, and shear stress applied with specially designed pliers.

RESULTS

The greatest strain was measured at the periodontally compromised tooth site 32 in response to frontal and lateral torquing. Both techniques also resulted in great strain around the other three teeth. Strain was markedly lower with the shear technique and virtually negligible with the compression technique. All simulated tooth sites confirmed the PDL-sparing effect of bracket-wing compression.

CONCLUSION

The severity of PDL strain during orthodontic bracket removal depends on the debonding method used. The technique of compressing the bracket wings appears to trigger the smallest effect on PDL. Clinical studies should be undertaken to confirm these findings.

Orbital and facial fractures

This article reviews the importance of particular radiologic findings related to facial trauma and their implications for clinical and surgical management. An emphasis is placed on critical imaging signs that warrant immediate surgical attention.

Critical thinking in patient centered care

Health care providers can enhance their critical thinking skills, essential to providing patient centered care, by use of motivational interviewing and evidence-based decision making techniques.

BACKGROUND AND PURPOSE

The need for critical thinking skills to foster optimal patient centered care is being emphasized in educational curricula for health care professions. The theme of this paper is that evidence-based decision making (EBDM) and motivational interviewing (MI) are tools that when taught in health professions educational programs can aid in the development of critical thinking skills. This paper reviews the MI and EBDM literature for evidence regarding these patient-centered care techniques as they relate to improved oral health outcomes.

METHODS

Comparisons between critical thinking and EBDM skills are presented and the EBDM model and the MI technique are briefly described followed by a discussion of the research to date.

CONCLUSIONS

The evidence suggests that EBDM and MI are valuable tools; however, further studies are needed regarding the effectiveness of EBDM and MI and the ways that health care providers can best develop critical thinking skills to facilitate improved patient care outcomes.

Massachusetts emergency departments' resources and physicians' knowledge of management of traumatic dental injuries

BACKGROUND

Hospital emergency departments (ED) are confronted with triaging and managing dental emergencies of both traumatic and non-traumatic origin. However, the literature suggests that there exists inadequate knowledge of the management of traumatic dental injuries (TDI) among medical professionals who must be knowledgeable and have the appropriate resources needed to triage or treat patients presenting with TDI.

AIM

The aims of this study were to (i) evaluate the resources of Massachusetts emergency departments (MEDs) for TDI, (ii) determine the knowledge of management of TDI among MED physicians, and (iii) investigate potential factors that affect their knowledge.

MATERIALS AND METHODS

Surveys were mailed to MED directors and their physicians. The director survey contained questions regarding institutional information for each emergency department (ED). The physician survey contained questions about physician characteristics and tested their knowledge of managing dental trauma.

RESULTS

A total of 72 surveys (16 MED directors and 56 physicians) were returned and included in the analysis. Only 50% of the MEDs had on-site dental coverage, 43.8% had 24-h off-site dental coverage, and none had a formal written dental trauma protocol. MED physician's knowledge of the appropriate management of luxations and avulsions was generally good, but poor for dental fractures. The MED physician's knowledge for the emergent nature of the various injuries was generally good with that of avulsions being the best. Physicians were more likely to have a better knowledge of managing dental trauma if they were specialists in pediatric emergency medicine (P = 0.001) or their hospitals had an academic affiliation (P = 0.05).

CONCLUSIONS

Based on the findings from this study, educational campaigns must be undertaken to improve both the resources available to the ED, and the knowledge of physicians regarding emergency management of TDI. In addition, efforts should be made by local dental organizations to provide ED with lists of dentists who are knowledgeable and willing to be available 24 h day⁻¹ to consult with and, if necessary, treat TDI. These efforts would enhance the long-term outcomes for patients sustaining dental trauma who present to hospital ED.

Prevalence and nature of dentoalveolar injuries among patients with maxillofacial fractures

OBJECTIVE

Although not previously reported, experience suggests that dentoalveolar injury is -common among patients with maxillofacial fractures. The objective of this study was to evaluate and describe the prevalence and nature of dentoalveolar injuries in patients identified with maxillofacial fractures.

METHODS

Medical records of 43 dogs and cats diagnosed with maxillofacial fractures between 2005 and 2012 were reviewed to identify patients with concurrent dentoalveolar injury. Medical records of patients with dentoalveolar injury were abstracted for the following information: signalment (including sex, age and skull type), mechanism of maxillofacial trauma, location and number of maxillofacial fractures, dentoalveolar injury type and location and the number of dentoalveolar injury per patient. Statistical evaluation was performed to determine associations between signalment, mechanism of trauma, location and number of maxillofacial fractures and the prevalence and nature of concurrent dentoalveolar injury.

RESULTS

Dentoalveolar injuries are common among patients with maxillofacial trauma. Age and mechanism of trauma are significant predictors of the presence of dentoalveolar injuries in patients with maxillofacial trauma.

CONCLUSIONS AND CLINICAL RELEVANCE

The findings of this study serve to encourage veterinarians to fully assess the oral cavity in patients with maxillofacial fractures as dentoalveolar injuries are common and can be predicted by age and mechanism of trauma.
