Effect of wire diameter and extent of wire composite splint on the mobility of luxated and anchor primary teeth: A typodont study.

BACKGROUND/AIMS: The recommendations for splinting are well established for the injuries of permanent dentition; however, ambiguity still exists for the injuries in primary dentition. Hence, this study aimed to determine the most appropriate dimensions of stainless steel wire and its extent, for achieving the physiologic mobility in primary dentition. MATERIAL AND METHODS: This study was designed as an in vitro experiment by using a typodont model of primary dentition. The baseline mobility of primary maxillary incisors was calibrated to the physiologic mobility of natural primary incisors by using a Teflon tape wrapped around the roots of resin teeth. Splinting was done using a stainless steel wire of 0.2 mm (Group I), 0.3 mm (Group II), and 0.4 mm (Group III). These groups were subdivided (a, b, and c) on the basis of the extent of the splint, and pre splint mobility (Pre-PV) and post-splint mobility (Post-PV) were tested by Periotest M. The splint effect was calculated by subtracting Post-PVs and Pre-PVs. RESULTS: The normal values of mobility in healthy human volunteers ranged from 10.5 to 13. The overall splint effect was higher in Group III irrespective of the extent of the splint, whereas it was found to be the lowest in Group I (b and c). The splint effect increased with the extent of the splint in all the groups. Among all the groups, the splint effect on the anchor teeth was observed to increase with the extent of the splint and the diameter of the wire. CONCLUSION: The mobility of the injured and anchor teeth splinted with 0.2-mm stainless steel wire was similar to the pre-splint and physiologic mobility. The most favorable extension was one tooth adjacent to the injured tooth on each side for both 0.2- and 0.3-mm wires.

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.

Prevalence of Traumatic Injuries to Primary Anterior Teeth among Children aged 2-6 Years in National Capital Region of Delhi, India.

AIMS: The aim of this study was to assess subject wise and tooth wise distribution and prevalence of traumatic injuries to the anterior teeth of 2- to 6-year-old children. MATERIALS AND METHODS: A cross-sectional survey was performed. Primary maxillary and mandibular anterior teeth of 1,800 children aged between 2 years and 6 years, who attended 20 pre-schools in National Capital Region Delhi, India, were examined by a single examiner, and a questionnaire was filled in person by the parent/guardian. Andreasen's classification was used to classify the traumatic injuries. The Chi-square test was used to statistically analyze the variation in traumatic dental injuries (TDIs) with age and gender. Multiple logistic regression was used to determine the influence of independent variables on the occurrence of TDIs. RESULTS: The prevalence of TDIs was 17%. Significant and highly significant differences were found between boys and girls for cause and location of trauma (p < 0.05) and tooth type involved (p < 0.001) with boys being more prone to such injuries. The commonest cause of injury was due to falls and the location was playground. The teeth most commonly affected were the maxillary central incisors (36.9%) followed by maxillary lateral incisors (3.3%), and the least affected were the maxillary and mandibular canines (0.3%). CONCLUSION: The prevalence of traumatic injuries to the anterior teeth in 2- to 6-year-old children in National Capital Region of Delhi, India, was 17%. There is a need to run educational programs to increase parents' awareness of the risks of dental trauma and emphasize preventive measures. CLINICAL SIGNIFICANCE: Parents should be made aware of the widespread prevalence, risk factors, and consequences of trauma to primary dentition, so that they can seek appropriate care timely. The time elapsed between injury and dental care is of utmost importance.

Root Fracture and Extrusive Luxation in Primary Teeth and Their Management: A Case Report.

BACKGROUND: Extrusion, lateral luxation, and intrusion are among the most serious types of dental trauma. Only a few studies have specifically focused on extrusion; the present one was aimed at reporting a case of domestic traumatic dental injury to primary tooth and describing the measures taken in managing the trauma in order to avoid future consequences to the underlying permanent tooth germ. CASE REPORT: A 3.5-year-old boy reported a dental injury with extrusion and root fracture of deciduous tooth 5.1. After intraoral and radiographic evaluation, the element was repositioned and stabilized by an orthodontic flexible splint attached to the adjacent teeth. Several follow-up checkups were made and showed good healing of the tissues and physiological exfoliation of the tooth, with a healthy and unaffected corresponding central permanent incisor. CONCLUSION: This case report strengthens the importance of well-timed diagnosis and treatment and of regular follow-up of traumatized teeth as they may affect both dentitions with a negative impact on Oral Health-Related Quality of Life. Conservative treatment should be taken into consideration when possible, being in some cases more appropriate.

Managing a Complex Crown Fracture in 1892 - Treatment Highlights within Current Contemporary Practices.

Historically, many teeth that had been traumatized resulted in extractions and replacements with a fixed partial denture (bridge). However, in rare situations some clinicians provided creative approaches to tooth retention much like what is done today, 125 years later.

Traumatic dental injuries in the primary dentition - a review.

Traumatic oral injuries in children involve trauma to the dentition and the surrounding oral soft tissue structures. They usually present as an emergency hence their management poses a challenge globally. Treatment of a tooth fracture, displacement or loss is determined by the type and severity of the injury independent of the etiology. It necessitates the experience for behavior management in a child, ascertaining a patient centered diagnosis, formulating a definitive treatment plan, explanation and consent of oral care to the parents or carer with optimal operator skills. This article provides an overview on the types of oral injury in a child patient, their recognition, diagnosis and management based on credible, practical and readily understandable evidence.

Nasopalatine canal and periapical radiolucency fusion following dentoalveolar trauma: A CBCT-based case-control study.

BACKGROUND/AIM: There is a lack of evidence regarding the radiological characteristics of a periapical radiolucency (PRL) fusion with the nasopalatine canal (NPC) following dentoalveolar trauma. The aim of this study was to assess the NPC enlargement resulting from fusion with a PRL and its relationship with the surrounding anatomical structures. MATERIAL AND METHODS: A total of 100 patients was retrospectively recruited and divided into two groups: case group and control group. The case group consisted of 50 cone-beam computed tomography scans of the maxilla of patients (32 males, 18 females; age range: 11-83 years) with a known history of dentoalveolar trauma in the maxillary anterior region and the presence of an undiagnosed and/or asymptomatic NPC and PRL fusion. An age- and gender-matched control group of 50 patients (32 males, 18 females; age range: 11-82 years) without trauma history to the upper anterior teeth, demonstrating normal maxillary scans, was recruited. A subjective scoring criterion was established for assessing the characteristics of the fused lesion and its relationship with the buccal/palatal alveolar cortex, nasal cavity cortex, NPC cortical border, and maxillary sinus floor. RESULTS: The fused NPC and PRL was mainly lobular in appearance (88%) with non-corticated well-defined margins (80%). Male patients showed larger (68%) dimensions compared with female patients (32%). The NPC cortical bone was the most commonly perforated structure in relation to fusion (72%), whereas maxillary sinus cortical bone was the least effected (2%). A statistically significant difference was observed between the NPC dimensions in the control and test groups, with fused lesions having larger mesiolateral, craniocaudal, and buccopalatal dimensions (P < .001). CONCLUSIONS: Periapical radiolucencies should be treated as soon as possible before they fuse with NPC. In case of fusion, surgical enucleation should be considered as the treatment of choice.

Esthetic Rehabilitation of Primary Anterior Teeth using Temporization Material: A Novel Approach.

Pediatric dentists should always aim for esthetic and functional rehabilitation of decayed/traumatized primary teeth. The most common method for restoring such teeth involves the use of "strip crowns" with composites, while the recent trend is toward using other extracoronal restorations including preve-neered stainless steel crowns and zirconia crowns. All these restorative options have shown good success rates, but also have some limitations. This case series depicts novel clinical technique of using a temporization material for full-coronal restoration(s) in primary anterior teeth. This included the chair-side custom fabrication of full-coronal restoration using temporization material, which has resulted in good immediate esthetics and might be a cost-effective alternative for restoring primary anterior teeth in future.

Physiological Root End Closure in a Traumatized Young Permanent Tooth Using Collagen Particles as Pulpal Dressing.

The management of traumatized young permanent teeth has always been a challenge to the clinician, considering the importance of retaining the vitality of the tooth. Recently, collagen particles have been successfully used as pulpotomy medicaments in primary teeth. This case report shows the use of collagen particles as pulpal dressing in a traumatized young permanent tooth of a nine-year-old child presenting with complicated fracture of young permanent left maxillary central incisor. Partial pulpotomy was performed with collagen particles (Biofil-AB) as pulpal dressing. At six months follow up, apexogenesis was found to be nearly complete. Thus, collagen can be considered as a potential pulpal medicament for apexogenesis procedures.

Smartphones and dental trauma: the current availability of apps for managing traumatic dental injuries.

BACKGROUND/AIM: There is a general consensus regarding the lack of awareness regarding the emergency management of traumatic dental injuries amongst laypersons and dental professionals. This article aims to provide an overview of the apps available for traumatic dental injuries using smartphones. These apps may serve as a gateway for raising awareness of traumatic dental injuries. MATERIALS AND METHOD: Three smartphone devices were used to access their respective app stores (Nokia Lumia 635 with Windows Phone OS 8.1; iPhone 5 with iOS 8.1; Samsung Galaxy Ace II with Android OS v2.3.6 Gingerbread). Nine phrases were searched: broken tooth/teeth; chipped tooth/teeth; dental emergency; dental injury; dental trauma; fractured tooth/teeth; knocked-out tooth/teeth; tooth/teeth injury; and tooth/teeth trauma. RESULTS: Seven apps for the Android and one app for the Apple operating system were relevant. The only Apple iOS app retrieved (Dental Trauma) was also found for the Android OS (Dental Trauma First Aid) and had the endorsement of the International Association of Dental Traumatology. AcciDent was the only app dedicated to traumatic dental injuries targeted solely towards dental professionals. Five other apps (Chipped Tooth Solution, Dental Crown Repair, Fixing Cracked Tooth, Repairing the Front Tooth and Solution to Broken Tooth) appeared to come from the same source (KBES). No traumatic dental injury apps were found for the Windows Phone OS. CONCLUSION: There are apps available for both patients and dentists that range in quality and on the whole lack real-life photographs. Future apps should continue to provide good quality, evidence-based and validated material.

Diagnóstico do trauma oclusal: extrapolações para a região óssea peri-implantar podem ser feitas / Diagnosis of occlusal trauma:extrapolations for peri-implant bone region can be done

As imagens oferecem uma linguagem que revela o dinamismo tecidual ósseo. A densidade óssea e a configuração espacial variam em suas estruturas e indicam uma menor ou maior reação e capacidade de adaptação às demandas funcionais, como cargas mastigatórias nos dentes naturais ou nos implantes osseointegrados. No planejamento de um tratamento reabilitador, é fundamental planejar a distribuição de carga e avaliar as condições dos dentes remanescentes e sua relação com o osso vizinho. Detectar a resposta óssea ao trauma oclusal preexistente pode favorecer uma avaliação mais precisa das condições mastigatórias e dos vícios parafuncionais: uma verdadeira história prévia funcional dos dentes remanescentes. Ressalta-se que as interferências e sobrecargas oclusais demoram meses, ou anos, para induzir os sinais e sintomas clássicos do trauma oclusal enquanto entidade clínica. Quando o dente apresenta-se com necrose pulpar e com sinais de trauma oclusal, o ideal será direcionar a anamnese e exames para um diagnóstico de traumatismo dentário superposto, mesmo em dentes posteriores. Não há fundamentação científica segura para afirmar-se que interferências ou sobrecargas oclusais provocam necrose pulpar. Um questionamento muito comum: até que ponto as forças ortodônticas de ancoragem podem ser aplicadas nos implantes osseointegrados? As forças ortodônticas não superam, em qualquer situação, a intensidade, amplitude e variabilidade das forças oclusais. Se um implante pode receber cargas mastigatórias, o mesmo pode se aplicar às forças ortodônticas de ancoragem.

Images provide a language to describe the dynamics of bone and tissue. Bone density and space distributionvary and indicate greater or lower reaction and adaptation to functional demands, such as masticatory loads,on natural teeth or osseointegrated implants. In rehabilitation, load distributions have to be planned, and theremaining teeth and their relation with neighboring bone should be evaluated. The detection of bone responsesto pre-existing occlusal trauma may provide a more accurate evaluation of masticatory conditions and parafunctionalhabits, that is, a true functional history of remaining teeth. Occlusal interference and overloads takemonths or years to induce classical signs and symptoms of occlusal trauma as a clinical entity. When a toothhas pulp necrosis and signs of occlusal trauma, the evaluation of history, as well as all tests, should be directedto the diagnosis of superposed dental trauma even when posterior teeth are affected. There is no scientific basisto confirm that occlusal interferences and overloads lead to pulp necrosis. A frequent question: Up to whatpoint should orthodontic forces be applied to osseointegrated implants? Orthodontic forces are not greater, inany situation, than occlusal forces in terms of intensity, amplitude and variability. If an implant can bear masticatory loads, it may also receive orthodontic forces resulting from anchorage.

A conservative approach toward restoration of fractured anterior tooth.

Reattachment of the fractured anterior tooth is a highly conservative and aesthetic treatment that has gained popularity in the recent past. Presented here is one such case in which a combination of external enamel bevel and internal dentinal groove has been used to enhance the bonding between the fractured fragment and the remaining tooth. The treatment was found to be successful both functionally and aesthetically at the 18-month follow-up.
