“…In our study, the PBF levels of the traumatised teeth were approximately 25 AU (26.32 ± 17.14), which were similar to the results reported by Setzer et al and Todea et al [23,24]. In the period immediately after the trauma, changes in the vascularization of the pulp tissues and its dynamics have occurred due to the injury, resulting in a statistically significant increase in the PBF levels of the affected teeth in the test group compared to those in the control group.…”

“…In this context, results of studies conducted by Akpinar et al, Gopikrishna et al and Polat et al have reported false-positive outcomes due to the interference of laser transmission in case of discoloration of the tooth crown or contamination of the backscattered light from the periodontal tissues [ 26 , 27 , 28 ]. The following factors have a great impact on the accuracy of the LDF values: the probe design and its position, single or multiple isolated teeth and the mineral contents of the inspected hard dental tissues [ 14 , 23 , 26 ]. Hence, future studies need to investigate the implementation of a new non-invasive technology, as a diagnostic tool of traumatised teeth.…”

Aim: This study aimed to evaluate the efficacy of laser Doppler flowmetry (LDF) in determining the changes in the pulpal blood flow (PBF) during post-traumatic period of the traumatised permanent teeth. Methods: 88 teeth of 44 patients (mean age 10.30 ± 2.38) were recruited according to the eligibility criteria and divided into two groups: test group (44 traumatised teeth) and control group (44 sound and healthy teeth). The measurement of PBF was performed, using a LDF monitor. Results: The analysis of the LDF outcomes in function of diagnosis indicated that the measurements of the traumatised teeth were significantly higher than those of non-traumatised teeth (p ˂ 0.05). Conclusions: LDF application provides dentists with fundamental benefits in terms of an early and precise investigation of PBF. In addition, LDF is a useful monitoring tool for revascularization of traumatised teeth and reliable objective diagnostic indicator of pulp vitality. Trial registration: ClinicalTrials.gov (Registration number: NCT04967456).

“…The position of drilling corresponding to the test teeth in the impression was situated in the middle of the tooth surface and distanced from the gingival margin about 3-5mm [20], and the diameter of the drilling hole was consistent with the probe. The subjects were asked to keep in the seated, calm and relaxed state after the LDF was preheated and calibrated, and then the silicone rubber impression was reset to the detected area in the test area (Fig 1[21]).…”

Aim: To measure the pulpal blood flow (PBF) of the upper incisors using the laser Doppler flowmetry (LDF) and to calculate the endodontic vitality clinical reference range using PBF as an indicator in the healthy children. To clarify the factors that might interfere the detection and interpretation of the results. Methods: Seven to twelve-year-old school-age children were recruited randomly. The basic characteristics of the subjects are described in terms of age and gender. The mean, standard deviation, and reference range of the subjects’ PBF values are described based on their age, sex, and tooth position. Multi-factor analysis of variance was implemented, mainly including age, gender, and tooth position. Results: 1) The clinical reference range of the anterior teeth PBF in children of different ages was preliminary defined that was approximately among the range of 7-14. 2). A statistically significant correlation between PBF and age in school-aged children (P < 0.05) was detected and no statistical significance between genders (P > 0.05) was detected. The PBF detection value of lateral incisors was higher than that of central incisors, and the difference was statistically significant (P < 0.05). Conclusion: The determination of the range of clinical reference of anterior teeth PBF in children by LDF could provide a good theoretical basis and reference basis for further promotion of its application.

Objetivo: Discutir todos os tipos de traumatismos dentários, descrevendo seus diagnósticos e planos de tratamento. Revisão bibliográfica: O traumatismo dental é uma emergência odontológica cujo tratamento frequentemente é multidisciplinar, sendo um problema de saúde pública pela alta prevalência. Pode acontecer em qualquer faixa etária, mais prevalente em crianças do gênero masculino. Por existir mais de um tipo de lesão, é primordial uma completa anamnese com auxílio de exames complementares, para obter um diagnóstico adequado, e com isso, realizar o correto tratamento a fim de obter prognósticos de forma satisfatória. Pode ser classificado de diversas formas diante de suas características clínicas, podendo variar desde trincas de esmalte a luxações. É importante o tratamento correto para cada caso e estes vão desde restaurações com resinas compostas, contenções, tratamento endodôntico e até mesmo o reimplante dental, devendo sempre avaliar possíveis sequelas em relação a cada caso individualmente. Considerações finais: Lesões dentárias traumáticas representam um desafio mundial, sendo fundamental a qualidade do tratamento de urgência, os cuidados domiciliares do paciente e o acompanhamento adequado, assegurando prognósticos favoráveis, limitando o surgimento de alterações pulpares e perirradiculares que, se diagnosticados e tratadas a tempo, poderão evitar a perda do elemento dental.
