Introduction: Cysts of the jaws constitute an heterogenous group of lesions occurring in the maxillofacial region. Their diagnosis is challenging and necessitating a meticulous correlation of clinical, radiological, and pathological features. Pathologists often face numerous difficulties stemming from inadequate clinical and radiological information, along with limited samples. Nevertheless, clinicians are not always aware of the pathologist's concerns, making difficult to know exactly which pertinent clinical information they should deliver in their request form. The objective of this article is to illustrate the microscopic diagnostic pitfalls associated with cystic lesions of the jaws and enhance communication between oral surgeons and oral pathologist. Corpus: This section starts by examining the essential clinical and radiological data necessary for a precise pathological diagnosis. Subsequently, we discuss about the differential diagnosis of jaw cystic lesions, categorizing them into five distinct subsets based on their microscopic features, particularly their histological lining. For each subset, we engage in a detailed discussion concerning the primary diagnostic challenges and their implications for treatment decisions. Conclusion: Pathologist and clinicians are not irreconcilables: improved communication, rooted in a mutual understanding of each other's concerns, leads to optimizing the diagnosis and subsequently the treatment of jaw cysts.

Objectives The indication for removal of asymptomatic fully impacted third molars is still controversial. In this study, radiological and histological investigation of the dental follicle of asymptomatic impacted mandibular third molars was performed, aiming to provide a reference for clinical prophylactic extraction of these teeth. Methods Patients with impacted mandibular third molars were included and the maximum width of the dental follicle around the crown was measured in horizontal, sagittal and coronal sections by cone beam computed tomography. The dental follicles were stained with haematoxylin-eosin, analysed by a pathologist and classified as normal, inflammatory or cystic. A Chi-squared test was used to analyse the association of the incidence of inflammation and cysts with the clinical variables of the impacted mandibular third molars. Results Thirty-seven samples were normal dental follicles; 52 samples showed inflammatory infiltration with an incidence of 57.14%; 2 samples with a maximum dental follicle width of 2–3 mm were diagnosed as odontogenic cysts, and the incidence was 2.20%. There was no significant difference in the incidence of inflammatory and cystic dental follicles between males and females, or between different age groups (P > 0.05). With an increase of the maximum width of the dental follicle, there was a rise in the incidence and degree of infiltration of chronic nonspecific inflammation. Conclusion Asymptomatic impacted mandibular third molars tend to be extracted, especially for teeth with a 2–3 mm maximum width of the dental follicle on radiological examination.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
