Agreement on Third Molar Classification
This observational and cross-sectional study design was developed in a private dental clinic from Aracaju, Sergipe, Brazil over the course of 12 months and was approved by the Ethics Committee in Research of University Hospital, Federal University of Ser-gipe, under number of protocol 0068.0.107.000-09. Initially, fifty digital panoramic radiographs which presented at least one lower third molar with indication for surgical removal were involved in this research.
From this initial sample, the study included patient radiographs of both males and females aged from 18 to 30 years. On the other hand, it excludes those radiographs which presented inappropriate technical standard, absence or bad positioning of the isolateral second molar and molars largely destroyed or reduced to roots fragments. Subsequently, twenty of the initial fifty radiographs were selected for inclusion in the research, totalizing 40 teeth for the agreement analysis.
These digital radiographs were impressed in photographic paper (Fujicolor Crystal Archive 20x28 cm), numbered from 01 to 20 and organized systematically. They were then individually evaluated by sixty examiners equally divided into two groups: under-graduates and professionals. Only undergraduates who had already completed the discipline of Oral and Maxillofacial Surgery were included in the group of 30 students. In turn, the 30 professionals were composed by 10 oral and maxillofacial surgeons (OMFS), 10 oral radiology specialists and 10 clinical dentists from Aracaju/Sergipe.
The lower third molars were analyzed and the examiners findings recorded on an objective formulary according to the following variables: angulation, class and position. Information about the criteria defined by both the Winter and the Pell & Gregory systems for third molars classification ( Table 1) were provided to all examiners before the radiographic analysis which ensured that this study was not evaluating the individual knowledge of examiners but rather to estimate the agreement degree for either of the two classification systems. During this study both the buccal and lingual inclinations of the Winter’s system were disregarded since an occlusal radiography, which would be required to record them, was not available.
All statistical analysis was done with the SPSS (version 17.0) statistical package. The level of significance was p< 0.05 and data were presented with 95% confidence intervals for the mean where applicable. Differences from baseline relative frequencies were equality distributed by Levene test and then the Variance Test – ANOVA was applied for the four groups of examiners, in order to analyze if there was significant difference inter-groups. Only in the statistically significant variables, a post-test (Bonferroni Test) was used with the purpose of identifying which examiner group demonstrated disagreement. The agreement intra-group of examiners was evaluated by descriptive analysis.

Developing a Dental Diagnostic Terminology
COHRI charged the diagnostic codes work group with developing a dental diagnostic terminology that 1) all COHRI members can utilize; 2) shall be easy to use, intuitive, and inclusive of existing terminologies because two schools have used the Z codes for many years and oral surgeons use the ICD system for surgical diagnoses; 3) shall be loaded into the EHR system; 4) shall be hierarchically organized to facilitate retrieval of terms and mappable to other terminologies and ontologies, such as SNODENT in the future; and 5) shall be developed for rapid implementation. There were two primary motivations driving the creation and development of the terminology. The first was to enhance the academic and clinical experience of dental students. The second was to facilitate the integration of data between dental schools and the data analyses for research and quality improvement purposes. It was furthermore decided that the diagnostic terminology created would be called “EZcodes.”

Formative and Summative OSCE Assessment of Head and Skull Examination
At the end of the module, the students who agreed to be videotaped participated in a formative videotaped assessment in the context of an OSCE station. The examination was performed on a standardized patient and was recorded. Afterwards the videos were shown to two examiners who were blinded with regards to the group assignment. They assessed the performance of the students with the standardized checklist (Additional file 2) used for head and skull examinations. The checklist is used in OSCE’s since 2007 and has been described previously [31 ]. The validation process of the checklist has been presented on the annual congress of the DGMKG (german society for cranio-maxillofacial surgeons) in 2009. The examiners were a second year resident (i.e., at the beginning of clinical training) and an attending doctor in the Department of CMF-Surgery. Both examiners rated the video material in an independent manner and assessed the students according to the OSCE checklist.
Four months after the skills lab week and the internship, the surgical OSCE took place as an obligatory final exam (summative).
Videotaping the entire exam was not possible since all students did not agree to being videotaped. For this reason, two examiners were at the head & skull examination of the OSCE station and rated the students. One examiner was an attending doctor in the Department of CMF-Surgery, the other examiner was an attending doctor in a related surgical discipline. These examiners were not members of the faculty and were also blinded with regards to group assignment. All raters participated in the mandatory examiner training at the faculty, which consists of a 30 min online tutorial and a 30 min simulation of a video rating.
Furthermore, we requested the time and the way of preparation the students prepared for the final OSCE exam referring to the head & skull examination, with a structured questionnaire.

Evaluating Oral Health in Patients
The OHAT score consists of eight categories with three possible scores (0 = healthy, 1 = some changes, and 2 = unhealthy) (Table 2) [14 (link)]. The total score is the sum of the various sub-scores. Based on the results of the dental examinations, including oral photographs and medical records, OHAT score of each patient was retrospectively evaluated by two observers (EI and KS). EI is an oral and maxillofacial surgeon with ≥ 10 years of experience, and KS is a dental hygienist with ≥ 10 years of experience. The OHAT-J, which includes images of each category and point scale in Japanese, is well-known among dentists and dental hygienists in Japan [21 ,22 ]. In this study, the dentist (EI) and dental hygienist (KS) evaluated the OHAT score after visual training and calibration by using this picture (S1 Data). Finally, the OHAT score of each patient was determined through discussion among the observers.

Retrospective Study of Ultra-Wide Dental Implants
This retrospective clinical study was conducted after receiving approval from the Institutional Review Board (IRB) of Seoul National University Bundang Hospital (IRB No. B-2208-774-111).
From January 2008 to December 2010, 81 subjects underwent dental implant placement therapy at the Department of Oral and Maxillofacial Surgery of Seoul National University Bundang Hospital. Eighty-eight ultra-wide implants with diameters of 6 mm and 7 mm were placed in 81 patients. Among them, 1 case was excluded due to the inability of follow-up checks because prosthetic treatment was not conducted at this hospital, 1 case was excluded due to the inability for evaluation because radiographs were not taken at the time of the final observation, and 14 cases within 12 months of the follow-up period after prosthetic loading were excluded from the study. As a result, a retrospective clinical study was conducted on 78 implants placed in 71 patients.
The reasons for using ultra-wide implants were as follows: First, an ultra-wide implant was selected as the initial choice due to poor bone quality. Second, if an implant with a diameter of 5 mm or less was attempted during surgery, but initial fixation was not obtained, an ultra-wide implant was used. Third, an ultra-wide was used for replacement after the removal of failed implants.(Table 1)
All patients underwent surgeries performed by one oral and maxillofacial surgeon, and primary stability was measured during the initial surgery, while secondary stability was measured for ultra-wide implants during the second surgery. All of the patients visited the hospital for a regular one-year check-up and underwent clinical examinations and periapical radiographs. Clinical examinations evaluated pocket depth, suppuration, and pus. MBL values were evaluated with periapical radiographs.
Resonance frequency analysis (RFA) was used to measure implant stability (primary and secondary). In this study, the implant stability quotient (ISQ) was measured and RFA was evaluated using an Osstell Mentor (Gothhenburg, Sweden), an integration diagnostic tool. The ISQ figure was recorded between 0-100 with the manufacturer statement of successful implants being above 65 ISQ, while values below 50 ISQ were the criterion for failure or risk of failure of the implant. Among the placed implants, primary stability was not measured for five implants and secondary stability was not measured for two implants.
The mean age of the patients was 54.2 years old with 39 males and 32 females. The age group in which implants were placed was the largest in their 50s, followed by those in their 60s and 40s.(Table 2) The mean healing period was 22 weeks after implant placement before prosthetic loading. The mean follow-up period for patients was 97.8 months. The healing period was set as the period from the time of surgery to second therapy or initial impression taking for prosthesis fabrication. The final observation period was set as the period from the time of prosthetic loading to the time of the final visit. The diameter and length of the implant, the implant site (upper/lower jaw), surgery stage, and the presence of additional surgical procedures (guided bone regeneration [GBR] and sinus lift) were evaluated.(Table 3)
The success and survival of the implants and MBL according to the variables were evaluated.

Surgical Removal of Metastatic Lymph Nodes
Within 2 weeks of CT scan, surgical removal of MLNs and MRLNs was performed bilaterally. Surgery was performed by a board-certified dentist and oral surgeon (SG) or board-certified oncologic surgeon (PA). Surgery was performed through two lateral incisions or a single ventral incision depending on surgeon preference. Intra- and post-operative complications were recorded.
Resected LNs were submitted for histopathological evaluation by a single board-certified pathologist (CB). Sectioning of LNs was performed as serial 2.5mm cross sections perpendicular to the long axis. All resulting pieces of tissue were processed, embedded, stained with hematoxylin and eosin, and examined histologically. Exceptions were made for LNs that were grossly enlarged, abnormal, and considered likely metastatic. For these LNs, representative sections were sampled to confirm metastasis, identify the tissue as LN origin, and determine presence or absence of extra-nodal extension. Histopathology results were reported as micro (< 2mm) or macro (>2 mm) metastasis.

Assessing Bone Quality via HU Analysis
To evaluate bone quality, HU values in the ramus were analyzed using Simplant software (Dentsply Sirona). HUs were measured in 2 rectangular areas in Images A and B. The rectangle was located 3 mm (anterior area) or 8 mm (posterior area) in front of the backward point (Fig 4A and 4B). The width of the rectangle was set at 1.5 mm, and the length was defined as the distance from the buccal surface to the lingual surface. Anterior and posterior HUs were defined as the average HU in Images A and B, respectively. These measurements were conducted 3 times by 2 oral surgeons, and the mean values were analyzed (S1C–S1F Fig in S1 Raw data). Measurements were performed once a month, and 2 surgeons performed the measurements individually.

Short Sagittal Split Ramus Osteotomy for Mandibular Prognathism
The Ethics Committee of the Faculty of Medicine, Tokyo Medical University reviewed and approved the study design (study approval number: T2021-0061). Informed consent was obtained from all individual participants included in the study. A total of 27 Japanese patients (13 men and 14 women) who were treated by SSRO at Tokyo Medical University Hospital between January and December 2020 were analyzed. The age of the patients at the time of orthognathic surgery ranged from 17 to 51 years (mean: 25.5 years; median: 24.0 years). SSRO procedures were performed basically according to the Hunsuck-Epker modification, which is known as short lingual osteotomy (SLO) [9 (link),10 (link)]. Patients who underwent extraction of the lower third molars or advanced movement of the proximal segment during SSRO were excluded. Patients who underwent advanced movement of the proximal segment during SSRO were also excluded because SSRO procedures in these patients were basically performed according to the Obwegeser-Dal Pont method. Features of the jaw deformities were mandibular prognathism with/without maxillary retrusion and/or facial asymmetry.
A modified version of SLO that has been described in a previous study [11 (link)], in which an ultrasonic bone-cutting device is used to determine the posterior osteotomy boundary, was performed in all cases. Briefly, after incision of the mucosa of the anterior border of the ramus, the periosteum was detached from the inferior border to the posterior border of the lateral aspect of the ramus, and then was also detached from the medial aspect extending horizontally in a posterior direction from between the sigmoid notch and mandibular foramen up to the posterior border of the ramus. Horizontal osteotomy was performed above the lingula of the mandible using a Lindemann bur. The cortical bone was cut from the lateral aspect of the anterior mandibular body to the medial aspect of the ramus using a reciprocating saw. Vertical osteotomy of about 10 mm was then conducted from the posterior edge of the horizontal osteotomy line toward the inferior border, using an ultrasonic bone-cutting device (SONOPET; Stryker Corporation) to split the sagittal surface of the ramus.
To ensure that all surgeries were performed using the same surgical technique, the chairman of our department, who has been performing craniofacial surgeries for more than 30 years and specializes in orthognathic surgery, participated and supervised all surgeries. The same instruments were used in all surgeries in this study. Nine surgeons, including the chairman, performed all operations. The 9 surgeons were all members of the Japanese Society of Oral and Maxillofacial Surgeons, who have been performing craniofacial surgery for 9 or more years.
