Friction is a fundamental aspect of orthodontic movement. Researchers and clinicians must be acquainted with its biomechanical and physical principles, as well as the potential alterations that may occur with the use of diverse materials. This literature review presents an approach of the physical principles at work in frictional mechanics, an analysis of the friction, at macro and microscopic level, of different orthodontic materials; describes the influence of friction on tooth movement and presents an update on friction research and its relationship to various materials.

Introducción: las personas que experimentan Ansiedad al tratamiento Dental (AD) pueden evitar las citas odontológicas e incluso posponer los tratamientos, incluyendo el tratamiento periodontal. El objetivo de este estudio fue 1) determinar la AD en pacientes con periodontitis antes del primer paso y después del segundo paso del tratamiento de la periodontitis (tratamiento periodontal no quirúrgico) y 2) recopilar características sociodemográficas y clínicas de la población estudiada. Métodos: se invitó a participar a pacientes con periodontitis que nunca habían recibido instrumentación subgingival, que asistían a la Clínica de Periodoncia de la Facultad de Odontología de la Universidad de Costa Rica. Del expediente electrónico se obtuvo la siguiente información: estadio periodontal, Índice de Placa (PI) e Índice de Sangrado Gingival (ISG). Se aplicó un cuestionario antes del primer paso y después del segundo paso del tratamiento de la periodontitis. Los datos recolectados incluyeron: factores sociodemográficos, hábitos de tabaquismo, condición de exfumador, dolor y la Escala de Ansiedad Dental de Corah Modificada (MDAS). Resultados: 51 pacientes completaron el estudio, 19 hombres y 32 mujeres, con un promedio de edad de 46 ± 11,16 años. La mayoría de los participantes refirió haber terminado la enseñanza media (37,3%). En cuanto al hábito de fumado, el 46% de los participantes eran no fumadores. De los no fumadores, el 7,8% eran exfumadores. El dolor máximo del paciente en el último mes disminuyó después de completar el segundo paso del tratamiento de la periodontitis (p=0,002). El diagnóstico periodontal más prevalente fue el Estadio III seguido del Estadio II. El PI medio fue del 61,4 % y el GBI medio fue del 39,5 %. El miedo al sonido de los instrumentos rotatorios y los raspadores ultrasónicos mejoró después del tratamiento periodontal. La AD se redujo en comparación con el valor inicial, según la puntuación total del MDAS y para todas las sub-puntuaciones del MDAS. Conclusión: la autopercepción de la AD mejoró en el trascurso del tratamiento periodontal en nuestro entorno clínico.
简介：有牙科治疗焦虑症（DAT）的人可能会逃避牙科就诊，甚至推迟治疗，包括牙周治疗。本研究的目的是：1）确定牙周炎患者在牙周炎治疗第一步和第二步（非手术牙周治疗）之前和之后的牙周治疗焦虑；2）收集研究人群的社会人口学和临床特征。方法：邀请哥斯达黎加大学牙科学院牙周病诊所从未接受过龈下器械治疗的牙周炎患者参与研究。从电子档案中获取了以下信息：牙周阶段、牙菌斑指数（PI）和牙龈出血指数（GBI）。在牙周炎治疗的第一步和第二步之前和之后进行了问卷调查。收集的数据包括：社会人口因素、吸烟习惯、戒烟状况、疼痛和改良科拉牙科焦虑量表（MDAS）。结果：51 名患者完成了研究，其中男性 19 人，女性 32 人，平均年龄为 46 ± 11.16 岁。大多数参与者表示已完成中学教育（37.3%）。在吸烟习惯方面，46%的参与者不吸烟。在不吸烟者中，7.8%曾经吸烟。完成牙周炎第二步治疗后，患者最近一个月的最大疼痛感有所减轻（P=0.002）。最常见的牙周诊断是 III 期，其次是 II 期。平均 PI 为 61.4%，平均 GBI 为 39.5%。对旋转器械和超声波洁牙机声音的恐惧在牙周治疗后有所改善。根据 MDAS 总分和所有 MDAS 分项得分，AD 与基线相比均有所降低。结论：在我们的临床环境中，牙周治疗过程中自我感觉的AD有所改善。

Introduction: therapeutic options for incisors affected by Molar Incisor Hypomineralization range from very conservative procedures to those considered to be more invasive. Clinicians must select the appropriate approach, considering the outcomes of the procedures. Methods: this case series presents clinical outcomes of five female patients with aesthetic complaints associated with the Molar Incisor Hipomineralization. Results: macroabrasion, microabrasion and dental vital bleaching were used as combination techniques in three cases. Resin infiltration was indicated for a specific case, considering the oncoming orthodontic treatment. Composite restoration was performed in one patient with posteruptive enamel breakdown. Conclusions: clinicians must select the appropriate approach according to an individualized evaluation of each case, considering factors such as the patient's expectations, dental age, psychosocial period, the severity of the condition, presence of sensitivity and the presumed aesthetic result of the selected treatment. The advantages and disadvantages of the techniques are presented.

Introduction: women and trans people who have engaged in sex work are triply vulnerable since they are victims of discrimination due to their employment status, their gender, and the risks that this work entails. This situation impacts their health situation. This study aimed to know the perceptions about health (physical, mental, and oral) of four women who work in prostitution in Medellin, based on their life experiences and those related to their social context. Methods: qualitative research with an ethnographic approach was conducted to analyze the situations mentioned. Four women participated, two Venezuelans and two Colombians, and semi-structured interviews were conducted. Qualitative content analysis was performed, which allowed the generation of four categories (mental health, oral health, general health, and quality of life). Results: her discourses made it possible to elucidate the connection between the living conditions and the health situation. The lack of job opportunities, a migratory process of profound economic and social changes, and a Colombia with inequities and barriers to access to health and social services are determining processes of a general and singular order of the precarious conditions of oral health and general. Conclusions: the participating population is in a situation of social and health vulnerability, which shows the need for public policies and strategies based on the social reality that contribute to generating equity in health.

Introduction: the Oroantral Communication (OAC) is the space that is created between the maxillary sinus and the oral cavity, which if not treated will progress to an Oroantral Fistula (OAF) or chronic sinus disease. The most common predisposing factor for a COA is the extraction of the upper posterior teeth (usually the first or second molars). The aim of this study was to carry out a literature review with emphasis on clinical implications and treatment alternatives of a COA through an update and review of information of interest. Methods: a literature review was carried out through a collection and analysis of bibliography of oroantral communications and the comparison and treatment alternatives. Discussion: various techniques have been proposed for the management of an AOC, among which are local flaps, as well as the use of biomaterials, which have given favorable results in closing the defect. Conclusion: the treatment of an AOC has as purpose to prevent its progression to an AFO, the development of sinusitis and/or that the defect increases; To do this, the clinician must be familiar with the various techniques based on the patient's needs.

Introduction: the in vitro study compared the dynamic cyclic fatigue resistance of 3 reciprocating NiTi files with heat treatment. Methods: we distributed 30 new endodontic files in three groups. The endodontic files selected for this experiment were: AF Blue R3 25/06 (AFB) (Fanta Dental, Shanghai, China), X1 Blue File 25/06 (X1B) (MK Life, Porto Alegre, RS, Brazil), and Reciproc Blue 08/25 (RB) (VDW, Munich, Germany. We measured the time to file fractureand the length of the fractured fragment. ANOVA analysis was used, followed by the Tukey test for multiple comparisons, with a significance level of 5% (P < 0.05). Results: the mean time in seconds until the file fractured was 170.7 ±15.1 for AFB files, 110.4 ±26.8 for X1B, and 163.3 ±22.9 for RB files. This difference was statistically significant when comparing X1B to AFB (p: 0.000) and X1B to RB (p: 0.000). However, there are no statistically significant differences between RB and AFB (p:0.739). Conclussions: this study found that RB and AFB files exhibit similar resistance to cyclic fatigue.
前言:体外研究比较了3种往复NiTi锉经热处理后的动态循环疲劳抗力。方法:将30个新根管锉分为三组。本实验选用的牙根管锉为:AF Blue R3 25/06 (AFB)(芬达牙科，中国上海)，X1 Blue File 25/06 (X1B) (MK Life，巴西RS阿雷格里港)和Reciproc Blue 08/25 (RB) (VDW，德国慕尼黑)。我们测量了锉状骨折的时间和骨折碎片的长度。采用方差分析，多组比较采用Tukey检验，显著性水平为5% (P < 0.05)。结果:AFB锉的平均骨折时间为170.7±15.1秒，X1B锉的平均骨折时间为110.4±26.8秒，RB锉的平均骨折时间为163.3±22.9秒。当比较X1B与AFB (p: 0.000)和X1B与RB (p: 0.000)时，这种差异具有统计学意义。然而，RB和AFB之间无统计学差异(p:0.739)。结论:本研究发现RB和AFB锉具有相似的抗循环疲劳性能。

Introduction: the objective of this study was to evaluate the relationship between incisor inclination at the end of orthodontic treatment with the anterior teeth alignment stability using PAR index. Methods: analytical cross-sectional study, the angle formed between the plane (Silla-Nasion) (U1-NS) and the inclination of the upper incisor and the angle between axial inclination of the lower incisor and mandibular plane (Go-Gn), were measured in 47 initial and final lateral radiographs of patients who finished orthodontic treatment. The anterior sector PAR index was applied to pretreatment (T0), posttreatment (T1) and follow-up (T2) casts. Statistical analysis was performed using frequency and percentage distributions, T test, Anova I, Anova II and Manova; significance p = 0,05. Results: no association was found between upper and lower incisor inclination, alignment stability and PAR weighted score between T2-T1 (p> 0,05). The PAR decreased 75,29% from T0 to T1 and 58,79% from T0 to T2, with a recurrence of 16,5%. There was no association between retainer type and PAR weighted score. From T0 to T2 there was an association between the interaction of the incisor inclination of upper (p = 0,03) and lower (p = 0,04), with the weighted total score of the PAR index. Conclusion: there was no association between the modification of the incisor inclination with the stability of the anterior sector. At the end of orthodontic treatment there was a high level of correction in the anterior-superior and inferior sector, however, there was a recurrence of 16,5%.

At the end of orthodontic treatment there was a high level of correction in the anterior-superior and inferior sector, however, there was a recurrence of 16,5%.","PeriodicalId":272900,"journal":{"name":"Revista Facultad de Odontología","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128323807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Introduction: Nickel-Titanium (NiTi) endodontic files are made of hyperelastic material with shape memory. However, these files suffer a sudden fracture during the endodontic treatment, which is considered an unfavorable prognosis. Many studies have been conducted to establish fatigue resistance focused on file brands and determine which is better. Although the most common failure mechanisms have been established for motorized endodontic files, the information is scattered, making it difficult to develop clear research trends. Methods: a scoping review was carried out using Scopus, Dimensions.ai, Web of Science, and Science Direct databases to answer screening questions related to the predominant fracture mechanism in NiTi files, test types, and equipment used for experimentation and to identify the most active authors.Results: using the general search terms, 432 research papers were found, of which 75 were finally selected after eliminating duplicates and applying exclusion criteria. Conclusions: typical failure mechanisms for rotatory and reciprocating files were identified based on the panoramic review and bibliometric indicators. Also, the standard mechanical tests for endodontic files and the characteristics of their assemblies were summarized. The most active authors in the area and their nationality were tagged. Finally, gaps for future research are proposed to generate a comprehensive knowledge of NiTi file failure.
镍钛(NiTi)牙髓锉是一种具有形状记忆的超弹性材料。然而，这些锉在根管治疗过程中会突然骨折，这被认为是一个不利的预后。已经进行了许多研究，以建立集中在文件品牌的抗疲劳性，并确定哪一个更好。虽然已经建立了电动牙髓锉最常见的失效机制，但由于资料分散，难以形成明确的研究趋势。方法:使用Scopus, Dimensions进行范围综述。ai、Web of Science和Science Direct数据库，以回答与NiTi文件中主要断裂机制、测试类型和用于实验的设备相关的筛选问题，并确定最活跃的作者。结果:使用一般检索词，共检索到432篇研究论文，剔除重复并应用排除标准，最终筛选出75篇。结论:基于文献计量指标和全景综述，确定了旋转和往复式文件的典型失效机制。综述了牙髓锉的标准力学试验及其组件的特点。对该地区最活跃的作者及其国籍进行了标记。最后，提出了未来研究的空白，以获得对NiTi文件失效的全面认识。

Dental extraction is one of the most common and most frequent surgical procedures performed by oral and maxillofacial surgeons. This surgical procedure is carried out in a controlled environment that ensures success in most cases. However, unexpected complications with a high risk of causing temporary or permanent disabling injuries may develop. This review focuses on rare complications that can occur when performing dental extractions. In order to fulfill the purpose of this review, a literature search was carried out in different databases; 34 articles reporting rare complications were selected, all were case reports. It was found that the most reported unusual complications after dental extraction were spinal epidural abscess and emphysema. Low mortality associated with these complications was also observed. Similarly, there are currently few publications on unusual complications as a result of tooth extraction. These rare complications should be reported more frequently in order to expand our Knowledge and to establish care protocols
