“…The average proportion of OTs among oral and maxillofacial lesions evaluated by histopathology increased from 3% (±2.9%) in studies that used the 1992 WHO classification of tumors to 4.0% (±1.3%) in those with the later classification ( 9 ). The mainstream of articles which were published after 2005 have used the 2005 WHO classification ( 7 - 14 ) except for few articles which used the latest 2017 classification ( 2 , 15 , 16 ). Therefore, in this study, we aimed to investigate the prevalence of OTs according to the WHO classification in 2017.…”

Background Odontogenic tumors (OTs) are considered important among oral lesions because of their clinicopathological heterogeneity and variable biological behavior. The purpose of this retrospective cross-sectional study was to evaluate the frequency and distribution of different types of odontogenic tumors based on the current 2017 WHO Classification of Head and Neck Tumors over a period of 5 years. This was achieved by reviewing the records of Cairo's educational hospitals and institutions and comparing the results with findings in the literature. Material and Methods The records of patients diagnosed with odontogenic tumors were obtained from six educational hospitals and a single institute in Cairo which included: Oral and Maxillofacial Pathology Department, Faculty of Dentistry, Cairo University; General Pathology Department, Faculty of Medicine, Cairo University; Oral Pathology Department, Faculty of Dentistry, Ain Shams University; Eldemerdash Hospital, Ain Shams University; El-Sayed Galal Hospital, Al-Azhar University; Ahmed Maher Teaching Hospital and National Cancer Institute. These records were reviewed over a 5-year (2014-2018) period and the odontogenic tumors were investigated for frequency, age, gender and site. The data were recorded, then analyzed using SPSS software. Results Intraosseous (central) odontogenic tumors constituted 2.56% of all 8974 registered oral and maxillofacial biopsies. A total of 230 cases of OTs were collected and reviewed. Of these, 97.8% were benign and 2.17% were malignant. The mandible was the most commonly affected anatomic location. Ameloblastoma, with a predilection for the posterior mandible, was the most frequent odontogenic tumor (55.65%), followed by cemento-ossifying fibroma (14.78%) and odontoma (9.13%). Females were more commonly affected than males. Most of the patients were in the third and fourth decades of life. There were no peripheral odontogenic tumors diagnosed in this period. Conclusions Some similarities and differences between our findings and those of previous studies of various populations were witnessed. OTs may greatly diverge according to the version of the classification used and by the sample size of the study. Retrospective analysis of the relative frequency of OTs in different countries will be helpful in enhancing the understanding of OTs, which is important for both oral maxillofacial surgeons and pathologists. Key words: Odontogenic tumors, epidemiology, world health organization classification, oral pathology.

“…8,27 Aiming to reduce these consequences, FNAC may be indicated because it is a low-cost and noninvasive technique; however, its use as a protocol for intraosseous jaw lesions is not unanimous. 13,19,26,28 Therefore, the present SR adds knowledge regarding the diagnostic capability of this technique, which could help to guide clinicians in making a more evidence-based decision when facing intraosseous jaw lesions on the daily clinical practice.…”

“…Even for experienced practitioners, the diagnosis of intraosseous jaw lesions can be difficult based solely on radiographic and clinical characteristics. Thus, for a more reliable diagnosis and correct surgical planning, a pretreatment IB is often chosen . However, this entails two surgical moments with consequences for the patient, such as pain, anxiety, and other risks arising from surgical intervention .…”

Purpose To systematically review (SR) and critically appraise studies that investigated the diagnostic capability of fine‐needle aspiration cytology (FNAC) in the assessment of intraosseous lesions of the jaws. Methods Six main electronic databases and three gray literature databases were searched aiming diagnostic studies, which were selected in a two‐phase process. Risk of bias (RoB) of included studies was assessed using the Revised Tool for the Quality Assessment of Diagnostic Accuracy Studies. Results A total of eight articles were included, of which six evaluated the FNAC smear technique exclusively, one assessed both smear and cell‐block techniques, while one investigated only the cell‐block technique. With regard to the FNAC smear technique, from 134 benign lesions investigated, concordance with the histopathological diagnosis was achieved in 64.17% of cases. In addition, considering the 32 malignant lesions assessed through this technique, concordance with histopathology was achieved in all cases. Regarding the cell‐block technique, only benign lesions (n = 40) were evaluated in the included studies, in which the concordance rate with histopathology was of 77.5%. The overall RoB judgment was “at risk of bias” for seven included studies mostly due to lack of information or reportedly absence of blinding of evaluator. Conclusions Within the limitations of this SR, FNAC presented modest to satisfactory diagnostic capability for the assessment of intraosseous jaw lesions, showing concordance rates higher than 64% for the smear and 77% for the cell‐block technique. Also, considerably high concordance rates were found for the assessment of malignant lesions regarding FNAC smear technique.

Objectives Due to time-consuming curricular and extracurricular activities, students in dentistry and medicine can profit from efficient learning strategies. One strategy could be the preparation with individually designed educational software that embed different multimedia sources. The aim of this study was to determine the efficiency of such a program compared with an e-book similar to a traditional textbook. Materials and Methods Dentistry students of the Johannes Gutenberg-University of Mainz passed an entrance multiple-choice test on the topic of odontogenic tumors and were then randomized into two groups. Afterward, both groups had 14 days to study on the topic of odontogenic tumors either with a learning software or an e-book. A final exam was then taken and the two groups were compared. Statistical Analysis A least significant difference post hoc analysis comparing the group average values was performed. The level of significance was p <0.05. Results Seventy-one students took part in the study. While students from the first and second clinical semester showed significantly better results and improvements with the e-book, an opposite effect was observed in students from the third and fifth clinical semester with significantly better results and improvements with the software. Conclusion Depending on the clinical experience and knowledge, a multimedia educational software can help students in dentistry to enhance efficiency in the preparation for exams.
