RESUMO

O anseio por um sorriso harmônico tem se tornado cada vez maior, uma vez que muitos pacientes relatam desconforto ao sorrir, pois correlacionam a estética do sorriso a problemas de baixa autoestima e em alguns casos suscetibilidade a alterações psicossociais decorrente aos padrões estéticos impostos pela sociedade. O sorriso gengival é uma das grandes queixas relatadas por pacientes. A exposição excessiva de gengiva maxilar pode ser decorrente a fatores gengivais, ósseos, dentários e musculares. Dentre os tratamentos disponíveis para diminuir essa exposição, contamos com cirurgias periodontais, aplicação de toxina botulínica, tratamentos ortodônticos, cirurgia ortognática e reposicionamento labial. O tratamento adequado será definido de acordo com o fator etiológico de cada caso. Diante disso o objetivo do trabalho é realizar um relato de caso sobre aumento de coroa clínica estética. A paciente estava descontente com a exibição de uma grande quantidade gengival ao sorrir. Após estudos clínicos e de imagem o diagnóstico foi de erupção passiva alterada, tipo IB. O tratamento de escolha foi a gengivoplastia associada a remodelação óssea osteotomia e osteoplastia. O tratamento estético vai além de uma boa aparência, através deste trabalho, foi possível evidenciar impactos benéficos que o sorriso harmônico pode acarretar na vida do indivíduo, atendendo suas expectativas e a do cirurgião-dentista(AU)


The desire for a harmonic smile has become increasing, since many patients report discomfort when smiling, as they correlate smile aesthetics to problems of low self-esteem and in some cases susceptibility to psychosocial changes due to aesthetic standards imposed by society. Gummy smile is one of the major complaints reported by patients. Excessive exposure of the maxillary gingiva may be due to gingival, bone, dental and muscular factors. Among the treatments available to reduce this exposure, we have periodontal surgeries, botulinum toxin application, orthodontic treatments, orthognathic surgery and lip repositioning. The appropriate treatment will be defined according to the etiological factor of each case. Therefore, the objective of this work is to carry out a case report on aesthetic clinical crown augmentation. Patient discount with the display of a large amount of gingival when smiling. After clinical and imaging studies, the diagnosis was an altered passive eruption, type IB. The treatment of choice was gingivoplasty associated with bone remodeling, osteotomy and osteoplasty. Final comments and conclusions: The aesthetic treatment goes beyond a good appearance, through this work, it was possible to evidence beneficial impacts that the harmonic smile can have on the individual's life, meeting their expectations and that of the dentist(AU)

RESUMO

BACKGROUND: Utilizing Blended pedagogy (BP) in radiographic skills may prove to be an effective teaching strategy. However, studies on the use of BP in dentistry are quite limited in Pakistan, where teaching has mostly been via traditional Didactic Lectures (DL); and radiographic interpretation skills of undergraduate dental students are suboptimal. Therefore, this study aims to assess whether utilizing BP to teach radiographic interpretation skills is an effective teaching methodology in Pakistan. METHODS: This mixed-method study was conducted on final year dental students at Jinnah Medical and Dental College (JMDC). Two groups of students were utilized for this study, one taught by traditional DL and the other taught by BP for the same module. BP was conducted over six weeks. A post-module test was conducted in both groups. Additionally, the BP group completed a modified Community of Inquiry (CoI) survey tool and volunteered to discuss their experiences through a focused group discussion (FGD). Descriptive statistics were computed and independent sample t-test was used to analyse the difference between the scores of the two groups. Thematic analysis was performed for the qualitative data. RESULTS: The mean post-test scores were found to be significantly higher in the BP group (61.0 ± 10.2) compared to the DL group (44.4 ± 12.3) (p = < 0.001, CI = 95%, Cronbach Alpha > 0.8). The mean scores for the modified CoI instrument were 4.0 ± 0.29 for the whole instrument; 4.25 ± 0.22 for Teaching Presence, 3.71 ± 0.23 for Social Presence and 3.97 ± 0.16 Cognitive Presence, with all three having a Cronbach's alpha > 0.75. Thematic analysis revealed that BP students mutually agreed that BP method was beneficial with the appreciation of strong support from the facilitator. However, challenges like interrupted power supply and increased effort requirement from students were pointed out. CONCLUSION: Students taught radiographic interpretation skills with BP in comparison to DL had higher test scores and expressed a positive experience demonstrated via a modified CoI survey and FGD. Considering the encouraging results found, dental schools should incorporate BP in their teaching methodology and follow-up studies are needed to further support the use of BP as an effective teaching methodology in Dentistry.

RESUMO

Dental academia in Pakistan has recently achieved an important milestone. The name of Operative Dentistry speciality has been changed to Operative Dentistry & Endodontics (ODE). It was a much-needed change that was first felt about two decades ago. However, with the correction of name, there are certain challenges that this speciality has to manage now. These include improving the curriculum, setting up standards, and lastly, setting up its boundaries and scope of practice as some of its scope overlaps with a sister speciality called Prosthodontics. This overlapping of the boundaries of dental disciplines is a problem that is unique to Pakistan, India, and some East Asian countries where Operative Dentistry or Conservative Dentistry is combined with Endodontics. This paper aims to discuss the objective delineation of dental procedures and suggest a model of peaceful co-existence of sister dental specialities.

RESUMO

Aim: To assess the opinion of the students on the impact of COVID-19 pandemic on theoretical knowledge and clinical practice in dentistry at the Piracicaba Dental School ­ FOP/UNICAMP. Methods: A questionnaire was applied using the Google Forms platform, containing 20 questions related to the impacts of the pandemic on knowledge, mental health, and clinical and laboratory practice of dentistry. The satisfaction of the students with teaching was also evaluated. A total of 120 questionnaires were analyzed using R software, through tables and graphs of absolute and relative frequencies distribution. Results: COVID-19 affected the lives of 99% students who participated in the study. Due to distance learning resulting from the COVID-19 pandemic, 50% of the students considered locking or dropping out of college. Operative dentistry was the curricular component most affected by distance and lack of clinical practice. Although most students agreed that the workload of practical disciplines was or would be replaced, 95% felt some kind of deficit in clinical and laboratory practice even with the replacement of the workload. In addition, 93.3% of the students were afraid of not becoming a qualified professional due to the deficiencies on theoretical knowledge and clinical practice caused by the pandemic. Conclusions: Students showed dissatisfaction with the deficiency of clinical and laboratory practice resulting from the pandemic in operative dentistry curricular component. They reported fear and insecurity with their future professional lives. The indication of remote classes for dentistry should only be carried out in emergencies because this is an essentially practical course that suffers losses in learning

RESUMO

The dental operative microscope has been widely employed in the field of dentistry, particularly in endodontics and operative dentistry, resulting in significant advancements in the effectiveness of root canal therapy, endodontic surgery, and dental restoration. However, the improper use of this microscope continues to be common in clinical settings, primarily due to operators' insufficient understanding and proficiency in both the features and established operating procedures of this equipment. In October 2019, Professor Jingping Liang, Vice Chairman of the Society of Cariology and Endodontology, Chinese Stomatological Association, organized a consensus meeting with Chinese experts in endodontics and operative dentistry. The objective of this meeting was to establish a standard operation procedure for the dental operative microscope. Subsequently, a consensus was reached and officially issued. Over the span of about four years, the content of this consensus has been further developed and improved through practical experience.

RESUMO

BACKGROUND: The development of competencies in dentistry is a complicated process that calls for the development of not just cognitive and psychomotor abilities but also behaviors and attitudes that change as technical proficiency increases and meaningful patient encounters occur. This study examined the relationship between the number of clinical requirements completed by dental students and subsequent performance on tests of competence. The null hypothesis stated there would be no significant linear relationship different from zero between absolute clinical requirements and grades attained in various tests of clinical competence. METHODS: Retrospective assessment data for 81 students were used in this analysis. Data included the amounts of clinical requirements completed for operative dentistry, endodontics, periodontics, and fixed prosthodontics together with data on the respective performance in tests of competence. Correlation was ascertained between grades for tests of competence and the corresponding clinical requirements using a non-parametric Spearman's Rho test at an alpha level of 0.05. RESULTS: Fixed prosthodontics and posterior endodontics were the least common procedures completed by dental students. Statistically significant weak correlations were found between the amounts of clinical requirements performed for posterior endodontic(p = 0.005) and operative procedures (p = 0.006) and associated performance in tests of competence. A moderate correlation was found between the number of fixed prosthodontic procedures completed and associated performance in tests of competence. This latter correlation, however, was not statistically significant (p = 0.654). A significant weak correlation was found between requirements completed for periodontics and the associated test of competence (p = 0.04). A highly statistically significant moderate correlation was found between clinical requirements for anterior endodontics and the associated performance in the tests of competence (p < 0.001). CONCLUSION: The null hypothesis was rejected since a positive correlation was found between the absolute clinical requirements completed and grades in tests of competence. However, only a weak to moderate degree of correlation was found between the completion of clinical requirements and performance in tests of competence for common clinical procedures that new dental graduates should be able to perform.

RESUMO

La extracción dental es uno de los ejercicios más practicado entre dentistas y maxilofaciales. Actualmente en España la prevalencia de extracciones realizadas es del 32,1%, de los cuales el 23,6% son cordales. La extracción de un tercer molar puede ser muy variada, desde un acto de pocos minutos y gran simplicidad a una complicada y extensa cirugía. Son diver sas las complicaciones que pueden de rivar de ello, las inmediatas que ocurran intraquirúrgicamente o las mediatas, a las horas o días. La aparición de dichas complicaciones está influenciada por diversos factores como edad, sexo, medicación, hábitos, enfermedades y diente extraído. El objetivo de este estudio fue describir la tasa de complicaciones en las exodoncias de terceros molares erupcionados a priori sin necesidad de abordaje quirúrgico, realizadas por los alumnos del grado en Odontología de la de la Universidad Europea de Madrid. Un total de 311 extracciones de terceros molares erupcionados, realizadas entre los años 2018-2020 por alumnos de la Policlínica de la Universidad Europea de Madrid fueron analizadas. Se registraron la edad, sexo, diente extraído, hábitos, enfermedades, medicación habitual, medicación pautada por el operador, motivo de extracción, estado periodontal y complicaciones. El análisis de los datos se realizó con el paquete estadístico Stata IC v. 15.La edad media de los pacientes fue 48,3 (DE: 14,01) años, habiendo una equidad en el género. El molar extraído con mayor frecuencia fue el 2.8. La tasa de complicaciones fue del 4,5% (IC95%: 2,04% – 6,97%), un dato inferior al encontrado en la literatura, prevaleciendo la frac tura de corona o raíz (4,5%) y la alveolitis con un 1,93%.La tasa de complicaciones reflejada en este estudio es in ferior a la publicada por otros autores; posiblemente debi do a la elección de casos más sencillos para ser realizados por aquellos con menor experiencia (AU)


Dental extraction is one of the most practiced exercises among dentists and maxillofacial surgeons. Currently in Spain the prevalence of extractions performed is 32.1%, of which 23.6% are wisdom teeth. The extraction of a wisdom tooth can be very varied, from an act of a few minutes and great simplicity to a complicated and extensive surgery. There are several complications that can derive from it, the immediate ones occurring intraoperatively or the mediate ones, after hours or days. The appearance of these complications is nfluenced by various factors such as age, sex, medication, habits, diseases and extracted tooth. The aim of this study was to describe the rate of complications in extractions of erupted third molars initially without the need for surgical approach, performed by students of the bachelor in Dentistry of the European University of Madrid. A total of 311 extractions of erupted third molars performed between the years 2018-2020 by students of the polyclinic of the European University of Madrid were analyzed. Age, sex, extracted tooth, habits, diseases, regular medication, medication prescribed by the operator, reason for extraction, periodontal status and complications were recorded. Data analysis was performed with the Stata IC v. 15 statistical package. The mean age of the patients was 48.3 (SD: 14.01) years, with gender equality. The rate of complications was 4.5% (95%CI: 2.04% – 6.97%), lower than that found in the literature, with a prevalence of tooth fracture (crown or root) (4,5%) and dry socket (1.93%). The rate of complications reflected in this study is lower than that published by other authors; possibly due to the choice of simpler cases to be performed by those with less experience (AU)

RESUMO

Las enfermedades cardiovasculares constituyen una de las patologías sistémicas más prevalentes en el mundo occidental. Muchos pacientes cardiópatas han tenido un episodio coronario agudo y están siendo tratados con antiagregantes plaquetarios. La terapia con estos fármacos puede suponer un reto para el odontólogo, que debe enfrentarse a un importante dilema: o mantener el fárma co, con el consiguiente riesgo hemorrági co, o retirarlo, con la posibilidad de que se produzcan complicaciones tromboembólicas, suponiendo un riesgo para la vida del paciente. Por ello, los odontólogos deberíamos conocer cuál debe ser el manejo de este tipo de pacientes ante la perspectiva de realizar un procedimiento quirúrgico en la cavidad oral o incluso una simple extracción dentaria. Los objetivos de esta revisión narrativa son, en primer lugar, recordar la fisiología plaquetaria y los mecanismos de forma ción del trombo plaquetario; en segundo lugar, profundizar en los mecanismos de acción de los diferentes fármacos antia gregantes plaquetarios; y, en tercer lugar, ya que no existen guías clínicas al res pecto, realizar un abordaje crítico de las pautas existentes para el manejo odonto lógico de este tipo de pacientes, en aras de prevenir la aparición de posibles com plicaciones, no solo locales, sino, lo que es más importante, complicaciones sisté micas. En estos casos, antes de retirar la terapia antiagregante, convendría sope sar el riesgo hemorrágico versus el riesgo de generar un nuevo episodio tromboem bólico, como puede ser la trombosis dstent o la recidiva del accidente coronario agudo, eventos que podrían poner en riesgo la vida del paciente (AU)


Cardiovascular disease is one of the most prevalent systemic pathologies worldwide; those patients usually have had an acute coronary event which is treated with antiplatelet therapy. These drugs represent a challenge for the dentist, who must face a major dilemma: either maintain the drug, with the consequent bleeding risk, or withdraw it, with the possibility of thromboembolic complications, entailing a risk to the patient’s life. Therefore, dentists should know how to manage patients treated with these drugs when performing a surgical procedure or even a simple tooth extraction. The objectives of this narrative review are, firstly, to recall platelet physiology and the mechanisms of platelet thrombus formation; secondly, to go more deeply into the mechanisms of action of the different antiplatelet drugs; and thirdly, since there are no clinical guidelines on this topic, to critically review the existing guidelines related to the dental management, in order to prevent the appearance of possible complications, not only local, but more importantly, systemic complications. In these cases, before interrupting antiplatelet therapy,the risk of bleeding should be evaluated against the risk of generating a new thromboembolic episode, such as stent thrombosis or recurrence of the acute coronary accident, events that could put the patient’s life at risk (AU)

RESUMO

BACKGROUND: Dental education has placed continued emphasis on self-regulated learning (SRL) and its subprocess, self-assessment. This study set out to evaluate the effectiveness of a novel workplace assessment method in developing trainees' self-assessment of operative procedures. METHODS: A Direct Observation of Procedural Skills (DOPS) form was modified for the use and measurement of self-assessment. Participants were trained on how to conduct self-assessment using the designed assessment form and its grading rubric. Feedback and feedforward sessions were given to address self-assessment and performance issues. A P-value less than 0.10 was considered significant and the confidence level was set at 90%. RESULTS: Thirty-two Year 5 dental students with an age mean of 22.45 (SD = 0.8) completed five self DOPS encounters during the clinical operative dentistry module in 2022. The aggregated total deviation (absolute difference) between self-assessment and teacher assessment decreased consistently in the five assessment encounters with a significant mean difference and a medium effect size (P = 0.064, partial Eta squared = 0.069). Participants' self-assessment accuracy differed from one skill to another and their ability to identify areas of improvement as perceived by teachers improved significantly (P = 0.011, partial Eta squared = 0.099). Participants' attitudes towards the assessment method were positive. CONCLUSIONS: The findings suggest that the self DOPS method was effective in developing participants' ability to self-assess. Future research should explore the effectiveness of this assessment method in a wider range of clinical procedures.

RESUMO

This prospective study aimed to present, compare, and evaluate the suitability of five different magnetic resonance imaging (MRI) protocols (3D double-echo steady-state (DESS), 3D fast spin echo short-tau inversion recovery (SPACE-STIR), 3D fast spin echo spectral attenuated inversion recovery (SPACE-SPAIR), volumetric interpolated breath-hold examination (T1-VIBE-Dixon), and ultrashort echo time (UTE)) and for orthopantomogram (OPG)-like MRI reconstructions using a novel mandibular coil. Three readers assessed MR-OPGs of 21 volunteers regarding technical image quality (4, excellent; 0, severely reduced), susceptibility to artifacts (3, absence; 0, massive), and visualization of anatomical structures in the oral cavity and surrounding skeletal structures (4, fine details visible; 0, no structures visible). Average image quality was good (3.29 ± 0.83) for all MRI protocols, with UTE providing the best image quality (3.52 ± 0.62) and no to minor artifacts (2.56 ± 0.6). Full diagnostic interpretability of the osseous structures is best in VIBE-Dixon and UTE MR-OPGs. DESS provided excellent visualization of the finest details of the nervous tissue (3.95 ± 0.22). Intra-reader and inter-reader agreement between the readers was good to excellent for all protocols (ICCs 0.812-0.957). MR-OPGs provide indication-specific accurate imaging of the oral cavity and could contribute to the early detection of pathologies, staging, and radiological follow-up of oral and maxillofacial diseases.

RESUMO

MRI is increasingly used as a diagnostic tool for visualising the dentoalveolar complex. A comprehensive review of the current indications and applications of MRI in the dental specialities of orthodontics (I), endodontics (II), prosthodontics (III), periodontics (IV), and oral surgery (V), pediatric dentistry (VI), operative dentistry is still missing and is therefore provided by the present work.The current literature on dental MRI shows that it is used for cephalometry in orthodontics and dentofacial orthopaedics, detection of dental pulp inflammation, characterisation of periapical and marginal periodontal pathologies of teeth, caries detection, and identification of the inferior alveolar nerve, impacted teeth and dentofacial anatomy for dental implant planning, respectively. Specific protocols regarding the miniature anatomy of the dentofacial complex, the presence of hard tissues, and foreign body restorations are used along with dedicated coils for the improved image quality of the facial skull.Dental MRI poses a clinically useful radiation-free imaging tool for visualising the dentoalveolar complex across dental specialities when respecting the indications and limitations.

RESUMO

OBJECTIVES: Approaches for combining scores have been based on weighted mean (WM) without consideration for psychometric characteristics of each individual assessments. This study evaluates consequences of WM and composite score (CS) approach. METHODS: Data from two longitudinal cohorts (n = 219) were utilized for performance in three Operative Dentistry courses as basis to compare the two score-combining methods. Four assessments (two written and two practical exams) from each course were combined using WM and CS approaches. WM scores were calculated by multiplying the score by its weight and summing across assessments. The CS approach follow a modification of the Kane and Case method, by standardizing scores, taking into account the reliability and associations between each assessment score. t-Tests and Pearson's correlation were used to evaluate the consequences of the WM and CS approaches. In addition, changes in each student's rank across WM and CS were determined. RESULTS: Combining scores using CS method produced lower scores and higher percentage failure in all courses compared to WM. Students ranks were changed significantly when CS was used with only 15% of the cohorts retained their ranks. CONCLUSIONS: CS produced a composite that is correlated with WM but still being substantively different providing meaningful and psychometrically rigorous information.

RESUMO

To test and evaluate the second installment of DENTIFY, a virtual reality haptic simulator for Operative Dentistry (OD), on preclinical dental students, by focusing on user performance and self-assessment. Twenty voluntary unpaid preclinical dental students, with different background experience, were enrolled for this study. After the completion of an informed consent, a demographic questionnaire, and being introduced to the prototype (on the first testing session), three testing sessions followed (S1, S2, S3). Each session involved the following steps: (I) free experimentation; (II) task execution; S3 also included (III) completion of questionnaires associated with the experiment (total of 8 Self-Assessment Questions (SAQ)); and (IV) guided interview. As expected, drill time decreased steadily for all tasks when increasing prototype use, verified by RM ANOVA. Regarding performance metrics (Comparisons by Student's t-test and ANOVA) recorded at S3, in overall, a higher performance was verified for participants with the following characteristics: female, non-gamer, no previous VR experience and with over 2 semesters of previous experience of working on phantom models. The correlation between the participants' performance (drill time), for the four tasks, and user self-assessment evaluation, verified by Spearman's rho analysis, allowed to conclude that a higher performance was observed in students who responded that DENTIFY improved their self perception of manual force applied. Regarding the questionnaires, Spearman's rho analysis showed a positive correlation between the improvement DENTIFY inputs on conventional teaching sensed by students, also enhancing their interest in learning OD, their desire to have more simulator hours and the improvement sensed on manual dexterity. All participating students adhered well to the DENTIFY experimentation. DENTIFY allows for student self-assessment and contributes to improving student performance. Simulators with VR and haptic pens for teaching in OD should be designed as a consistent and gradual teaching strategy, allowing multiplicity of simulated scenarios, bimanual manipulation, and the possibility of real-time feedback to allow for the student's immediate self-assessment. Additionally, they should create performance reports per student to ensure self-perception/criticism of their evolution over longer periods of learning time.

RESUMO

OBJECTIVES: The aim was to investigate aspects of the teaching of restoration repair as a minimally invasive alternative to replacing defective direct composite restorations in undergraduate curricula teaching programs in Brazilian dental schools. METHODS: A 14-item validated survey questionnaire was mailed to directors/coordinators of operative/restorative dentistry teachers of Brazilian Dental Schools. Data were collected on demographic characteristics of the teachers and institutions, together with questions on the teaching of the repair of defective resin-based composite restorations as part of the school curriculum; the rationale behind the teaching; the nature of the teaching (preclinical and/or clinical); how techniques were taught, indications for repair, operative techniques, materials used, patient acceptability and expected longevity of completed repairs. RESULTS: Two hundred and twenty-two (94%) directors/ coordinators of dental curricula in Brazil were contacted. One hundred and thirty-one directors/coordinators (59%) replied, providing the e-mail address from the teacher responsible for the operative/restorative dentistry program in their school. Of these, 104 responded to the questionnaire (79% response rate). Ninety-three (89%) of the participating schools reported teaching composite repairs as an alternative to replacing restorations. Of the theoretical content, 43% was taught at preclinical and clinical levels, whereas most practical experience (53%) was acquired at clinical levels. Eighty-eight schools (95%) reported tooth substance preservation being the main reason for teaching repair techniques. All schools that taught repairs reported high patient acceptability. CONCLUSIONS: The teaching of composite restoration repair as an alternative to restoration replacement is established in undergraduate programs in most of the Brazilian dental schools surveyed. CLINICAL SIGNIFICANCE: The reasons for teaching restoration repair in Brazil were found to be quite unanimous among teachers, especially regarding the preservation of tooth structure. Variations were found in the clinical indications for repair, suggesting the need for further investigations. Monitoring repaired restorations should be encouraged and could contribute to future studies.

OBJECTIVES: To investigate the latest teaching policies for posterior resin composite placement versus amalgam and to determine the actual numbers of posterior resin composites versus amalgam restorations placed in American dental schools from 2008 to 2018. METHODS: Emails were sent to the deans of all 66 dental schools in the United States to collect data in the forms of: 1) Questionnaire on current teaching policies of posterior composite and amalgam restorations; and 2) Data entry form to collect the actual numbers of posterior composite and amalgam restorations placed in their clinics. Descriptive statistics were used to summarize ratios of posterior restorations. Inferential analysis (chi-square test and z-test) was employed to compare posterior restoration proportions over time and within each year. Level of significance was set at 0.05. RESULTS: For the teaching questionnaire, the response rate was 52% (n=34). Seventy-six per cent of the responding schools reported that they assign 50% or more of their preclinical restorative teaching time towards posterior resin composite placement, while 50% of the responding schools devoted 25% or less towards amalgam teaching. Data entry response rate was 26% (n=17). In 2008, amalgam and resin composite restorations were placed almost equally. However, resin composite restorations were placed significantly more frequently from 2009 onwards in all responding schools. The results revealed a significant ongoing increasing trend in placing posterior resin composites in all responding schools over time (p<0.05). CONCLUSIONS: Data analysis revealed a clear trend towards an increase in posterior resin composite restoration placement and a decrease in the number of amalgam restorations. However, the time assigned for posterior resin composite teaching is not aligned with quantity of restorations placed. Review and adjustment of the time allocated for teaching and training of each material are suggested.

RESUMO

The dental operative microscope has been widely employed in the field of dentistry, particularly in endodontics and operative dentistry, resulting in significant advancements in the effectiveness of root canal therapy, endodontic surgery, and dental restoration. However, the improper use of this microscope continues to be common in clinical settings, primarily due to operators' insufficient understanding and proficiency in both the features and established operating procedures of this equipment. In October 2019, Professor Jingping Liang, Vice Chairman of the Society of Cariology and Endodontology, Chinese Stomatological Association, organized a consensus meeting with Chinese experts in endodontics and operative dentistry. The objective of this meeting was to establish a standard operation procedure for the dental operative microscope. Subsequently, a consensus was reached and officially issued. Over the span of about four years, the content of this consensus has been further developed and improved through practical experience.
