RESUMO
Introduction: Developing regenerative endodontic treatment (RET) is an exciting approach to managing immature permanent teeth with pulp necrosis. RET is usually performed in two clinical steps: disinfection (first step) and tissue engineering (second step). Recently, laser therapy has entered the field of RET. This study aimed to provide an overview of the literature that employed laser therapy for root regeneration. Methods: A comprehensive search was performed on four databases, including PubMed, Web of Science, Scopus, and Google Scholar. The searched keywords were laser, regenerative endodontics, immature permanent teeth, and dental pulp necrosis, and related English-published articles were included up to October 2023. Results: Thirteen studies utilized a laser for RET. In the first step of RET, both high-power and low-level lasers (through photodynamic therapy [PDT]) may be applied for canal disinfection. In contrast, regenerative procedures in the second step of RET are just accelerated by low-power lasers (biostimulation). The literature does not support the benefit of laser-assisted irrigation in improving the clinical success of RET. There is some evidence that laser-assisted disinfection with a diode laser may provide comparable results to triple antibiotic paste in reducing bacterial counts in root canals while providing slightly better clinical and radiographic outcomes. PDT may be an effective and suitable adjunct to conventional disinfection methods in immature, necrotic teeth. Conclusion: Low-power lasers may be beneficial tools for improving the results of regenerative endodontics through chemical disinfection in the first step (PDT) or by biostimulation in the second step of RET.
RESUMO
Background: Trauma is a leading cause of death and disability in developing countries, with maxillofacial fractures being a significant part of such cases. This study focuses on maxillofacial traumas among insured patients in Razavi Khorasan province (2016-2021), exploring the impact of gender, age, and trauma causes on injury prevalence and treatment approaches. Methods: This retrospective cross-sectional study utilized the records of the patients who were treated for maxillofacial fractures in Mashhad Shahid Kamyab Hospital or a Private Trauma Center, from 2016 to 2021. Demographic characteristics of the patients (age and gender), educational backgrounds of surgeons, accident causes, year and location of the fractures, and reasons for referrals were recorded. The data were statistically analyzed using SPSS 20, and the significance level was set at 0.05. Results: We examined the records of 60 patients (44 males, 16 females). Males (73.4%) exhibited a significantly higher prevalence of maxillofacial traumas compared to females (26%) (P Value < 0.05). Falling was identified as the most common cause of fractures (51.7%), followed by impacts from hard objects and motor vehicle accidents (MVA) (P Value = 0.63). Mandible fractures were observed in 48% of patients, followed by zygomaticomaxillary and panfacial fractures, subsequently (P Value < 0.05). Conclusion: The study findings highlight the impact of age, gender, and trauma causes on maxillofacial fractures and treatments among patients with certain insurance. Understanding the origins and patterns of these fractures offers crucial insights for shaping effective health policies, providing valuable guidance for addressing such injuries in this population.
