Guidelines for the evaluation and management of traumatic dental injuries

Interim prosthesis design and socket preservation for a non-salvageable traumatic injury in a young adult: a minimalistic approach to traumatic injuries in children

Long-term prognosis of complicated traumatic injuries depends on precise treatment planning. Establishing a balance between a patient's age, prognosis, financial hurdles, and treatment needs is challenging. This case highlights the need for meticulous and realistic treatment planning to achieve long-term favourable outcomes in traumatic injuries in young adults.A young child sustained a traumatic injury that caused avulsion of #21 and intrusion along with palatal luxation of #11. The child reported to the dental clinic with intraoral swelling and pain a week after the injury. Socket preservation was done so that uniform bone contour could be achieved for implant placement at a later stage. We modified a 'Hollywood appliance' as an interim prosthesis to ensure that the ridge was not immediately loaded where socket preservation was done.After a follow-up of 3 years, there is significant bone deposition and the child is satisfied with aesthetics.

Effects of Er:YAG Laser on the Attachment of Human Periodontal Ligament Fibroblasts to Denuded Root Surfaces Simulating Delayed Replantation Cases: An In Vitro Study

Objective: To investigate the effects of Er:YAG laser on the attachment of human periodontal ligament fibroblasts (hPDLFs) to denuded root surfaces simulating delayed replantation cases. Background data: Dental avulsion is one of the most severe dental traumas, which is often treated with replantation. In delayed replantation scenarios, poor prognosis, including root resorption, usually occurs due to poor root surface conditioning and nonviable hPDLF attachment. Methods: Thirty-six root fragments (5 × 5 × 2 mm) were obtained from periodontium tissue-free premolar root surfaces. Specimens were randomly and equally assigned to the following: Group A, untreated control; Group B, 25 J/cm² and 10 Hz of Er:YAG laser irradiation; and Group C, 50 J/cm² and 10 Hz of Er:YAG laser irradiation. Some specimens in each group were then prepared for surface topography visualization under SEM, others were subjected to coculture with hPDLF suspension, and cell adhesion was further evaluated by SEM. Results: Group A presented homogenous smooth root surface, with fewer and round-shaped cells attached; Group B and C exhibited rather rough and irregular morphologies, and spindle-shaped fibroblasts were firmly attached by numerous lamellipodia and extensions. After a 3-day coculture, the number of fibroblasts attached in Group A was significantly lower compared with the other two laser-treated groups (p = 0.008 < 0.05). No significant alterations were observed between the two laser groups (p = 0.135 > 0.05). Conclusions: Er:YAG laser-treated root surfaces are compatible for the attachment of PDLFs, which suggests that Er:YAG laser irradiation may be used as a promising strategy for root surface conditioning in delayed replantation cases.

Guidelines for the Management of Traumatic Dental Injuries: 1. Fractures and Luxations of Permanent Teeth

Traumatic dental injuries (TDIs) of permanent teeth occur frequently in children and young adults. Crown fractures and luxations are the most commonly occurring of all dental injuries. Proper diagnosis, treatment planning and followup are important for improving a favorable outcome. Guidelines should assist dentists and patients in decision making and for providing the best care effectively and efficiently. The International Association of Dental Traumatology (IADT) has developed a consensus statement after a review of the dental literature and group discussions. Experienced researchers and clinicians from various specialties were included in the group. In cases where the data did not appear conclusive, recommendations were based on the consensus opinion of the IADT board members. The guidelines represent the best current evidence based on literature search and professional opinion. The primary goal of these guidelines is to delineate an approach for the immediate or urgent care of TDIs. In this first article, the IADT Guidelines for management of fractures and luxations of permanent teeth will be presented.

The association of overjet with traumatic dental injuries: a systematic review protocol

REVIEW QUESTION

The objective of this review of association (etiology) is to identify the relationship between different overjet measurements and developing a traumatic dental injury (TDI) across different dentition stages. Specifically, the review will elucidate the critical level, in millimetres, at which an overjet will place an individual at an increased risk of developing a TDI within each specific dentition stage. The specific review questions are.

National Athletic Trainers' Association Position Statement: Preventing and Managing Sport-Related Dental and Oral Injuries

OBJECTIVE

To provide athletic trainers, health care professionals, and all those responsible for the care of athletes with clinical recommendations for preventing and managing sport-related dental and oral injuries.

BACKGROUND

Participation in competitive sports continues to grow at both the interscholastic and intercollegiate levels. Therefore, exposure to, and the incidence of athletic-related injury, including orofacial injury, will also likely increase. At the time of this writing, the leading governing agencies for interscholastic (National Federation of State High School Associations) and intercollegiate (National Collegiate Athletic Association) sports require only protective orofacial equipment (eg, mouthguards) for 5 and 4, respectively, of their sanctioned sports. Although orofacial injuries represent a small percentage of all sport-related injuries, the financial burden associated with these injuries (eg, tooth avulsion) can exceed $15 000 over an adult life. Therefore, effective management of sport-related dental injuries is critical to the long-term financial, physical, and emotional health of people who have experienced dental trauma.

RECOMMENDATIONS

Based upon the current evidence regarding sport-related orofacial injury, we provide recommendations related to planning considerations, education, and mouthguard efficacy, material, fabrication, and care considerations. Additionally, suggested best practices for managing sport-related dental injury are also given for athletic trainers and other health care professionals.

Timely management of knocked out teeth - are the nurses aware?

AIMS AND OBJECTIVES

To assess working and trainee nurses' knowledge and awareness regarding the emergency handling of traumatic injuries to the teeth. The research was conducted in four different parts of Karnataka, a state in India.

BACKGROUND

Traumatic injuries to teeth and the facial region are common among children and young adults. Most traumatic dental injuries can be avoided, or would be less serious, if an extensive knowledge and awareness of these injuries existed, especially among people who frequently come across them.

DESIGN

The study is a cross-sectional, questionnaire-based survey conducted among nurses of Karnataka.

METHODS

The questionnaire was given to nurses in different parts of Karnataka, India. Six hundred and two nurses completed a 15-item questionnaire, assessing their knowledge and practices in the management of traumatic injuries to the teeth.

RESULTS

Most of the nurses knew that an avulsed tooth can be replaced in the socket and approximately 70% knew mouthguards and other protective measures are available. The nurses' knowledge was, however, inadequate given their exposure to emergency cases and this was borne out by the fact that the study subjects reported that they require still more adequate training in emergency handling of dental injuries.

CONCLUSION

This study reveals that nurses in the current study have less knowledge than expected. Sufficient training should be provided, not only to doctors and dentists in emergency departments, but also to paramedical technicians and nurses to ensure proper care and appropriate advice is available to parents of children experiencing dental trauma. Hence, this study recommends an extensive health education programme in this field.

RELEVANCE TO CLINICAL PRACTICE

As nurses play a vital role in the emergency dental services provided to patients, the importance of dental injury and its emergency management must be included in their curriculum.

Delayed removal of a primary incisor embedded in the upper lip after dental trauma: a case report about the importance of soft tissue examination

This article describes a child patient who initially had inadequate treatment and suffered concomitant soft tissue trauma involving complete displacement of a primary central incisor into the lip tissue. The primary tooth was subsequently removed by surgery under general anesthesia. Despite the delay in diagnosis, there was an excellent outcome following removal of the embedded tooth. This paper again emphasizes the importance of an accurate history, physical, and radiographic evaluation of these patients in the acute phase. The importance of soft tissue inspection even in cases that are presented late for dental trauma management is also highlighted. This case shows that educated emergency room staff preferably including an oral and maxillofacial surgeon is required for a proper emergency management in orofacial traumas.

The endodontic management of traumatized permanent anterior teeth: a review

Despite the many journal articles and reviews that have been published regarding the treatment of trauma to teeth, the endodontic management of these injuries is often still not fully understood. The purpose of this review is to establish clear and up-to-date guidelines for practitioners who are faced with treating dental injuries on a day-to-day basis, based on an assessment of current available scientific information relating to the endodontic management of these injuries. Treatment is discussed under the headings: infractions, uncomplicated crown fractures, complicated crown fractures, crown-root fractures, root fractures, luxation injuries, avulsion, root resorption, pulp canal obliteration and open-apex teeth. Emphasis is placed on the treatment of traumatized immature teeth where maintenance of pulp blood supply is important to encourage continued development of the root system. Only the treatment of traumatized permanent anterior teeth is reviewed. Information contained in this article is based on a review of the literature on dental trauma which involved a MEDLINE search using the key words "dental trauma" and the individual topics listed above. The guidelines produced by the International Association of Dental Traumatology, the American Academy of Pediatric Dentistry and the American Association of Endodontists were also reviewed and the recommendations contained in this paper are in concert with the major recommendations of these bodies.

Treatment of extrusive luxation by intentional replantation

BACKGROUND

The accepted treatment for extrusive luxation is repositioning of the extruded tooth at the earliest possible opportunity.

CASE REPORT

Repositioning was not possible in a patient who presented for treatment 4 days after the accident, and therefore, an intentional replantation was performed instead. The tooth was carefully extracted, the blood clot removed from the alveolus and the tooth was then replanted.

CONCLUSION

Intentional replantation involves the deliberate removal of a tooth and its reinsertion into the alveolus almost immediately afterwards. It is now an accepted endodontic procedure. The favourable outcome of this case suggests that intentional replantation of severely extruded teeth may be a treatment option in cases where the tooth cannot be repositioned and if treatment conditions are adequately followed.

Traumatic intrusion of permanent teeth. Part 3. A clinical study of the effect of treatment variables such as treatment delay, method of repositioning, type of splint, length of splinting and antibiotics on 140 teeth

A prospective study of 140 intruded permanent teeth was examined for the following healing complications: pulp necrosis (PN), root resorption (RR; surface, inflammatory and replacement resorption), and defects in marginal periodontal bone healing (MA). The occurrence of these healing complications was related to various treatment factors such as treatment delay, method of repositioning (i.e. expecting re-eruption, orthodontic reposition and surgical reposition), type of splint (rigid, semirigid and flexible), length of splinting (days) and the use of antibiotics. Treatment delay, i.e. before and after 24 h, had no effect upon healing. Active repositioning in individuals with incomplete root formation (surgical or orthodontic) had a negative effect upon the three healing parameters compared with spontaneous eruption. In teeth with complete root formation and an age of 12-17 no repositioning was still the best treatment in regard to MA. In individuals older than 17 years of age, cases were not anticipated to spontaneously erupt and in these cases, the general choice of treatment was either active orthodontic or surgical repositioning. The former procedure appeared in this treatment scenario to slightly reduce the risk of MA complications. However, this treatment procedure was also found to be more time demanding (an average of 22 consultations for orthodontic repositioning compared with 17 consultations for surgical repositioning). If a surgical repositioning was performed, the type of splint (i.e. flexible, semirigid or rigid) appeared to have no significant effect on the type of healing. The same applied to the length of splinting time (shorter or longer than 6 weeks). No effect of dentin covering procedures for associated crown fractures (enamel-dentin fractures) could be demonstrated. Likewise, antibiotics had no apparent effect upon healing. In conclusion, in patients with intruded teeth with incomplete root formation, spontaneous eruption should be expected. In patients with completed root formation and with an age of 12-17 spontaneous eruption can still occur, but must be monitored very carefully. In older patients (i.e. >17 years) with completed root formation, either surgical or orthodontic extrusion should be attempted. The latter procedure appeared to lead to a slight reduction (not significant) in the risk of MA complications. The extent and direction of the intrusion may however favour surgical repositioning.

Management of dental trauma in primary care: a postal survey of general dental practitioners

OBJECTIVES

To determine the self-perceived knowledge and attitudes of general dental practitioners (GDPs) concerning management of dental trauma in primary care. To identify potential barriers to the management of dental trauma in primary care.

DESIGN AND SETTING

A self-completion postal questionnaire survey of 417 GDPs in six local health authority districts in northeast England.

MAIN OUTCOME MEASURES

Likert scale responses to 20 statements designed to test self-perceived knowledge and attitudes. Following descriptive statistical analysis. Factor analysis with principle components analysis was undertaken to identify areas of correlation in questionnaire responses, followed by Chi squared test, Spearman's Rank Correlation and analysis of variance (ANOVA) to measure association between variables.

RESULTS

The response rate was 74%. Enamel and dentine fractures were the most common injury, with 45% of GDPs responding seeing more than 10 cases of dental trauma in the preceding year and 53% of respondents seeing one to three cases of complicated crown fracture. Seventy-eight per cent believed that NHS remuneration was inadequate, but only 8% would refer patients with dental trauma to secondary care for this reason. Half of the GDPs believed that trauma could be treated more effectively in practice if NHS payments were greater. GDPs were significantly more likely to agree with this statement if they had previously undertaken a postgraduate course in the treatment of dental trauma (p=0.002). Single handed GDPs were statistically significantly more likely to agree with the statements 'I would not treat dental trauma cases at my practice because the NHS payment is inadequate' (p=0.008) and 'Treating dental trauma at my practice requires too much of my clinical time to be worthwhile' (p=0.002). Ninety-six per cent of GDPs disagreed that treatment of dental trauma rested solely within secondary care. Ninety-six per cent of GDPs agreed that they had a responsibility to provide initial emergency treatment for trauma patients prior to referral. Eighty-eight per cent of GDPs felt that aids to management would be useful.

CONCLUSIONS

Although GDPs believed that financial remuneration was inadequate, this did not prevent them treating trauma cases. They strongly agreed that they had responsibility for the management of dental trauma in primary care and that they believed trauma could be treated more effectively in practice if payment was greater. Time constraints were perceived as a barrier to long-term management of complex trauma cases in primary care. GDPs would welcome the use of management aids.

Possibilities of preventing traumatic dental injuries: A prospective study

Introduction The aim of this study was to investigate the most important etiological factors related to traumatic dental injuries, type of required treatment, period from injury to initial treatment and Frequency of recall appointments. Material and methods The sample consisted of 283 children with dental injuries managed at the Department of Dentistry of the Faculty of Medicine in Novi Sad. during the last 7 years. Retrospective data relied on trauma protocols of this department, whereas collected data referred to etiological factors, type of initial treatment, period from injury to initial treatment, recall appointments and complications of traumatic dental injuries. These results were compared with other similar national and international studies, in order to promote implementation of preventive strategies that would reduce the increasing frequency of dental trauma. Results Fall accidents were the most common cause of dental trauma. Injuries were most frequent in autumn, in the street, and in the afternoon hours. Single tooth injury was predominant, while the injured mostly denied previous injuries. Almost half of the injured patients did not seek professional help in the first 24 hours after the injury. 40% of treated patients missed their recall appointment. Conclusion Knowledge of the etiology is important for planning preventive, measures, but because of the complexity of etiological factors, it is difficult to prevent traumatic dental injuries. It is also important to underline the importance of immediate initial treatment of traumatized patients, and significance of their regular professional supervision. Generally speaking, almost all treatment procedures in management of traumatic dental injuries include preventive component.

Post-traumatic use of dental implants to rehabilitate anterior maxillary teeth

The treatment sequel of post-traumatic teeth for the use of dental implants in the anterior maxillary region to rehabilitate anterior maxillary missing teeth was evaluated. Files of 53 healthy patients reporting anterior dental trauma were reviewed. All patients had an anterior maxillary dental implant because of tooth loss after trauma. At initial examination, 18 patients (34%) had root canal treatment and an inflammatory lesion, 15 (28.3%) had a missing tooth on admission, 12 (22.6%) had a prior operation (i.e. root-end surgery or crown lengthening), 4 (7.5%) presented an ankylotic root, and 4 (7.5%) had a root remnant not suitable for rehabilitation, with no inflammatory periapical lesion. Treatment sequences and complications were recorded. Augmentation procedure (i.e. onlay bone graft or guided bone regeneration) was performed in 43 patients (81.1%), and 2 patients (3.8%) had orthodontic extrusion prior to tooth extraction and implantation. Implants were placed immediately in 25 patients (47.2%) and 4 (7.5%) had immediate loading at the time of implantation. Complications and postoperative incidents (fistula, inflammation, swelling hematoma, etc.) were observed in 24 patients (45.3%). There was no difference in complication and postoperative incident rates with regards to the implantation technique. Complications were found at the prosthetic phase in seven patients (13.2%; six fistula and one implant failure). When patients were divided into two groups, with and without an inflammatory lesion, a significantly lower complication and postoperative incident rate were found in the non-inflammatory group (P = 0.057). This study reaffirmed the necessity for scrupulous diagnosis of teeth and alveolar bone after a traumatic injury. Treatment is multidisciplinary, requiring surgical, orthodontic, endodontic, operative, and prosthetic compliance. A specially designed treatment plan for each patient is necessary. General rules do not apply.

Treatment Options of Untreatable Traumatized Anterior Maxillary Teeth for Future Use of Dental Implantation

The anterior maxilla is the most traumatized region during childhood. Posttraumatic complications occasionally lead to tooth loss as well as the need for future implants. Unfortunately, it is contraindicated to place dental implants during childhood. A waiting period of approximately 8 to 10 years before completion of growth is required. For this patient to become a candidate for future dental implants, it is necessary to ensure the continuous growth and to preserve the dimensions of the alveolar process until growth has ceased from time of injury until joint maturation. To achieve these goals, it is essential to coordinate the treatment sequence at the time of trauma. After loss of a traumatized anterior permanent maxillary incisor in young adults, treatment options are limited: orthodontic closure of the gap and reshaping the adjacent teeth, or tooth extraction and maintaining the gap with a temporary restoration. Orthdontic space closure has limited indications and requires prosthetic restoration of at least 2 teeth. Extraction and temporary restoration will usually lead to bone augmentation before implantation. Other possible treatment options include orthodontic extrusion of the root remnant (in cases of untreatable root fracture or complicated crown-root fracture) and a temporary crown to serve the patient until the completion of growth and development, autogenous tooth transplantation, intentional extraction and immediate tooth replantation, distraction osteogenesis, and decoronation. Because general rules do not apply, individual treatment plans are necessary.
