The 2020 International Association of Dental Traumatology (IADT) Guidelines feature several important changes in the treatment recommendations for traumatic dental injuries (TDIs) from the previous 2012 iteration of these Guidelines. This evidence-based narrative review aims to provide a detailed appraisal of five specific changes incorporated in the 2020 IADT Guidelines, based on the available literature evidence that may have prompted these changes. The paper discusses three excellent additions/changes to the new Guidelines: (i) inclusion of a core outcome set for reporting TDIs; (ii) more conservative management of primary dentition TDIs including the changed recommendations for radiation exposure and managing primary dentition luxation injuries; and (iii) the changes in the treatment recommendations for permanent dentition avulsion injuries. The paper further debates whether two other changes made in the current IADT Guidelines for-(i) intrusion injuries in immature teeth; and (ii) complicated crown-root fractures in mature teeth-have sufficient evidence to support the changed recommendations.

OBJECTIVE: Many treatment options accepted for unsalvageable traumatized teeth in adults would seem contraindicated in children and adolescents. Instead, growing patients need interim restorative measures, thus extensively preserving their local bone and soft tissue structures and, ideally, preparing the involved site for later definitive restoration while they transform to skeletal maturity. This narrative topic review addresses the interim management in case of very deep intra-extra-alveolar fractures, extensive infection-related root resorption, tooth ankylosis, and anterior tooth loss in growing patients, and seeks to empower the clinician to select the appropriate treatment approach.
METHODS: The literature up to 2021 was reviewed based on several scoping searches on PubMed and the Cochrane Library using relevant terms. Due to the complexity of the topic (with various poor prognosis scenarios and the differing therapeutic options), a systematic review was deemed inappropriate.
CONCLUSIONS: Suitable interim treatment options include extrusion of teeth showing deep intra-extra-alveolar fractures, and decoronation of ankylosed teeth as well as resin-bonded fixed dental prostheses, natural tooth pontics, and primary tooth autotransplantations after tooth loss. The interim management options described in this article represent compromises chosen in the absence of better alternatives after a careful risk-benefit analysis. However, if adequately performed, the presented treatment options have the potential to achieve the temporary restoration of function and esthetics in growing patients. Close clinical and (if appropriate) radiologic monitoring of these patients is considered mandatory to ensure early detection of possible complications that might jeopardize or could render impossible subsequent therapeutic measures.

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 follow up 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 Hebrew Edition is part of the IADT global effort to provide accessibility to these guidelines worldwide.

OBJECTIVE: The purpose of this pilot study was to evaluate the relationship between the vertical position of the maxillary central incisal edge and the maxillary canine relative to the maxillary lip line in repose of dentate patients. This may be beneficial for clinicians in establishing guidelines for the rehabilitation of edentulous patients.
METHODS: One hundred and four Caucasian dentate patients (59 men and 45 women) between the ages of 30 and 59 years were evaluated. A millimeter ruler was used to measure the maxillary right central incisor edge and the maxillary right canine tip to the maxillary lip in repose. Data were collected in reference to sex and age.
RESULTS: For the female group, average central incisor exposure in relation to the relaxed maxillary lip line was 3.8 mm, and the range of exposure was -1 to +8 mm. In the 30- to 39-year olds (17 patients), the average was 4.1 mm with a range of 0 to 8 mm. The average in the 40- to 49-year-old group (16 patients) was 2.8 mm with a range of -1 to +6 mm. In 50- to 59-year olds (12 patients), the average was 1.8 mm with a range of -1 to +5 mm. In the male group, the average central incisor exposure was 2.5 mm, and the range was -3 to +7 mm. The average for the 30- to 39-year-old group (20 patients) was 3.2 mm with a range of 0 to 7 mm. For the 40- to 49-year group (18 patients), the average was 2.4 mm and for 50 to 61 years (21 patients), it was 1.4 mm with a range of -3 to +5 mm in both latter age groups. The canine position for the female group average exposure was 0 mm, with a range of -2 to +2 mm. For the 30- to 39-year old group, average exposure was 1 mm with a range of -1 to +2 mm. The 40- to 49-year-old group exposed an average of 0.4 mm with a range of -1 to +2 mm. For the 50- to 59-year old group, canine exposure was -0.5 mm with a range of -2 to +1 mm. The male average canine exposure was -0.5 mm, and the range was -3 to +2 mm. For the 30- to 39-year old group, the average was 0.9 mm with a range of -1 to +2 mm. The 40- to 49-year-old group exposed an average of 0.2 mm, with a range of -1 to +2 mm. For the 50- to 59-year old group, average was -0.9 mm with a range of -2 to +1 mm.
CONCLUSIONS: There was a large range of maxillary central incisal exposure in relation to the maxillary lip line. The average dimension of central incisor exposure represented less than 30% of the subjects in the study and could not be used predictably to assess incisal edge position. The range of canine exposure was narrower. The average dimensions of canine exposure to the lip were within 1 mm for both men and women in all age groups. Further studies are needed to confirm these preliminary results. The average dimensions for the different sex and age groups related to canine exposure represented a greater proportion of the subjects. Therefore, it is suggested that the average canine exposure dimension can be used clinically to assess anterior incisor edge position when restoring edentulous patients.

Crown fractures and luxations occur most frequently of all dental injuries. An appropriate treatment plan after an injury is important for a good prognosis. Guidelines are useful for delivering the best care possible in an efficient manner. 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 current best evidence, based on literature research and professional opinion. In this first article of three, the IADT Guidelines for management of fractures and luxations of permanent teeth will be presented.

Occasionally, patients require restorative treatment during or after orthodontic therapy. Patients with worn or abraded teeth, peg-shaped lateral incisors, fractured teeth, multiple edentulous spaces, or other restorative needs may require tooth positioning that is slightly different from a nonrestored, nonabraded, completely dentulous adolescent. Generally, orthodontists are not accustomed to dealing with patients who require restorative intervention. Should the objectives of orthodontic treatment differ for the restorative patient compared with the nonrestorative patient? How should the teeth be positioned during orthodontic therapy to facilitate specific restorations? Should teeth be restored before, during, or perhaps after orthodontics? The answers to these and other important questions are vital to the successful treatment of some orthodontic patients. This article will provide a series of eight guidelines to help the interdisciplinary team manage treatment for the orthodontic-restorative patient.
