Dental Traumatology

Tooth aspiration is one of the rare sequelae of dental trauma. When this does occur, the right bronchus is usually involved in adults due to the anatomical configuration. In this unusual case, two teeth were aspirated with one entering each lung. While the outcome from cases of aspiration of foreign bodies is usually favourable, this case serves to illustrate one of the possible unfavourable consequences.

Bilateral pulmonary aspiration of intact teeth following maxillofacial trauma

Abstract A material of 885 luxated, non‐vital incisors was evaluated radiographically with respect to healing of periodontal tissues including inflammatory root resorption and occurrence of ankylosis and cervical root fractures. The results were assessed after completion of calcium hydroxide treatment and 4 years after filling of the root canal with gutta‐percha. After treatment with calcium hydroxide, periapical healing occurred in 95% of the teeth. Four years after filling with gutta‐percha, periapical healing was present in 91% of the teeth. In the remaining teeth, recurrent or persistent periapical radiolucency was more frequent in overfilled than adequately filled teeth (P = 0.0001). There was no difference between immature and mature teeth. Inflammatory root resorption healed in 192 of 197 teeth (97%); in 5 teeth it developed into ankylosis. Ankylosis occurred in 13 teeth, all of which were intruded into the alveolar bone at the time of injury. The frequency of cervical root fractures was markedly higher in immature than mature teeth (P&gt;0.0001). Among immature teeth, the frequency of fractures was dependent on the stage of root development [x 2 = 31,6) and ranged from 77% in teeth with the least to 28% in teeth with the most developed roots. The frequency of fractures was also related to the defects after healing of inflammatory root resorption in the cervical area of the root, significant at P&lt; 0.0001.

钙羟基磷灰石治疗脱位无生机上颌切牙并充填古塔胶的预后：回顾性临床研究

Abstract – The main purpose of this review is to present the aetiological factors and the mechanism that cause dilaceration of the maxillary central incisors. In early developmental stages, the permanent tooth germ of the maxillary incisor is situated palatally and superiorly to the apex of the primary incisor and gradually changes direction in a labial direction with its crown coming closer to the resorbing primary root. For reasons of this close relationship between the permanent tooth germ and the apex of the primary incisor, it is believed that an acute trauma to the primary predecessor can cause dilaceration of the long axis of the permanent successor. Clinically, dilaceration can be revealed by palpation high in the labial sulcus or in the hard palate, while its radiographic view is characteristic. The therapeutic approach to the dilacerated maxillary central incisors has to be carefully planned and needs the cooperation of several specialities to attain the final objective.

Letter to the Editor

Abstract – This case report describes a 7‐year‐old boy who avulsed and inhaled a primary maxillary incisor. Over the next number of weeks, he developed a persistent, productive cough, which was unresponsive to antibiotic therapy. Radiographic examination revealed a small radiopaque tooth‐shaped object in the right hilar lung region. The aspirated tooth was subsequently successfully removed by bronchoscopy under general anaesthetic. Despite the delay in diagnosis, there was an excellent outcome following removal of the aspirated tooth.

Aspiration of an avulsed primary incisor: a case report

ABSTRACT Background/Aim Traumatic Dental Injuries (TDIs) are an emerging public health problem and a realm of research for oral health enthusiasts. Certain populations can be more vulnerable to injuries such as those with a sensory deficit. Nevertheless, literature is scarce, especially for those with hearing impairment. Therefore, the aim of the study was to compare the prevalence and patterns of TDI in children and adolescents with severe‐to profound hearing impairments and children without hearing impairments. Material and Methods Three hundred and ninety participants (195 severe to profound hearing impaired and 195 age and sex‐matched controls) between 4 and 18 years were recruited from a tertiary care setting. A single calibrated examiner evaluated TDI for both groups. Among those with TDI, a vestibular function test (VFT) was also performed to assess postural balance. A single examiner from the Department of Otorhinolaryngology evaluated the VFT results. Results The overall prevalence of TDI was found to be 12.82% among the severe to profound hearing‐impaired individuals, and 11.79% in controls. The majority of participants were aged between 7 and 13 years, in the mixed dentition stage, and were males. Among the cases, the majority had profound hearing loss (≥ 91 dB HL) and bilateral ear involvement. The most common type of TDI was uncomplicated crown fractures. Falls were identified as the most common cause of TDI in both groups. Vestibular dysfunction and loss of postural control were identified in 12 out of 14 patients tested with VFT. A significant association was found between TDI and the dentition type, that is, primary dentition was more affected among the severe to profound hearing impaired as compared to controls ( p &lt; 0.05). Conclusion There was no significant association between the severity of hearing impairment and the prevalence of dental trauma in children and adolescents with severe to profound hearing impairment. However, hearing‐impaired individuals were susceptible to trauma at an early age compared to their healthy counterparts.

Comparative Effectiveness of Regenerative Endodontic Treatment Versus Apexification for Necrotic Immature Permanent Teeth With or Without Apical Periodontitis: An Umbrella Review

再生根管治疗与根尖诱导成形术治疗伴有或不伴有根尖周炎的坏死未成熟恒牙的比较效果：一项伞形综述

ABSTRACT Calcium hydroxide apexification has been used in the treatment of immature teeth with pulp necrosis and apical periodontitis for more than 50 years. However, the guidelines of the European Academy of Paediatric Dentistry (EAPD) and the American Association of Endodontists (AAE) ‘Clinical recommendations for a regenerative procedure’ recommend against calcium hydroxide apexification. The American Association of Endodontists “Clinical considerations for a regenerative procedure” do not list calcium hydroxide apexification as a treatment option for immature teeth with pulp necrosis. This review analyses the strength of the science that led to calcium hydroxide no longer being recommended by the EAPD and AAE regenerative guidelines. Many differences in the studies and failure to include adequate controls have resulted in inconsistent outcomes between studies. Furthermore, prior in vitro studies have assessed narrow mechanical properties of teeth without a theoretical fracture mechanics model. Cvek's concerns regarding the thinness of the dentinal walls remain as a primary risk for tooth fracture with Class 3 root development fractured with an incidence of 77% compared to a fracture incidence of just 2% for mature teeth. This review develops a simple fracture mechanics approach to the phenomenon of transverse root fracture that provides a theoretical framework to why fragile roots are more likely to fracture when compared to mature teeth. Furthermore, the effect of the varying size access cavities has not been previously considered. Systematic reviews and clinical studies do attest to the success of all approaches for the treatment of immature teeth with pulp necrosis. Calcium hydroxide apexification is one of the recommended treatments in the International Association of Dental Traumatology guidelines. However, mineral trioxide aggregate (MTA) and hydraulic calcium silicate cements (HCSC's) may provide better outcomes and have the convenience for the patient of a shorter treatment time. Regenerative endodontic treatment (RET) is recommended when the tooth roots are very immature with Cvek Class 1–3 root development. However, the treatment of immature teeth with pulp necrosis remains a clinical challenge as does the risk of tooth fracture.

ABSTRACT Background/Aim The aim of this study was to investigate the impact of traumatic dental injury (TDI) on oral health‐related quality of life (OHRQoL) of preschool children, and further inform public oral health care policies and strategies for this age group TDI patients. Materials and Methods This retrospective and cross‐sectional study was conducted in the Department of Pediatric Dentistry, West China Hospital of Stomatology, Sichuan University, Chengdu, China. It included 314 children aged from 2 to 5 years, with 90 children diagnosed with TDIs and 224 without TDIs. Parents or primary caregivers completed questionnaires, and the responses were gathered for statistical analysis to evaluate the impact of TDIs. The OHRQoL was assessed using the Early Childhood Oral Health Impact Scale (ECOHIS). Results The total ECOHIS score and the scores for the 13 individual items were significantly higher in children with TDIs compared with those without TDI ( p &lt; 0.001). In the child impact section, eating and masticatory function were the most severely affected (40%), while most of parents experienced strong feelings of self‐blame in the family impact section (61.1%). A positive correlation was observed between the number of injured teeth and the total ECOHIS score ( p = 0.001), while the time elapsed since TDI indicates a negative correlation with the total ECOHIS score ( p &lt; 0.001). Additionally, children with severe TDIs had higher ECOHIS scores than those with mild TDIs, indicating a greater impact on OHRQoL ( p = 0.006). In contrast, tooth discoloration, the caregiver's relationship to the child, caregiver education level and the position of the affected teeth did not significantly influence the total ECOHIS score ( p &gt; 0.05). Conclusions TDIs have a significant impact on OHRQoL in preschool children, highlighting the need for greater societal attention. Strengthening preventive and proper treatment measures for TDIs, along with enhancing health education programs, is strongly recommended.
