Context: Glucose uptake may be considered the rate-limiting step for the growth and metabolism of the cancer cell. Studies on GLUT1 have shown that GLUT1 is involved in cell survival and proliferation in both healthy and pathological circumstances. GLUT1 expression is regarded as one of the crucial elements in the development of local aggressiveness, tumour invasiveness, and metastasis, particularly in malignant tumours. The role of glut1 in odontogenic cysts and tumours has remained uncertain.
Aim: The aim of the study is to assess the expression of Glut1 in dentigerous cysts, odontogenic keratocysts, and ameloblastoma.
Settings And Design: The study was conducted in GSL Dental College. The study design was a resprospective immunohistochemical study.
Methods And Material: Formalin-fixed, paraffin-embedded blocks of histologically confirmed cases (n = 50), 10 cases of odontogenic keratocysts, dentigerous cysts, ameloblastomas solid, ameloblastomas unicystic, and dental follicles each. Brown colour staining was considered as positive staining for GLUT1. Quantitative analysis was performed by counting the number of labelled cells, and semi-quantitative analysis was conducted by assigning immunostaining intensity scores.
Statistical Analysis: Chi-square test was used to compare differences between the groups. A value of ≤0.05 was considered as statistically significant.
Results: Odontogenic keratocysts and unicystic ameloblastoma showed ≥50% of label cells with strong intensity of staining. Odontogenic keratocysts and solid ameloblastoma showed sub-cellular localisation of staining in the cytoplasm and membrane. Dentigerous cysts exhibited combined nucleus, cytoplasm, and membrane sub-cellular localisation of staining.
Conclusions: The development of ameloblastomas, odontogenic keratocysts, and dentigerous cysts appears to be influenced by GLUT-1. Variation in its expression may aid in explanation of some of the differences in biological activity of these lesions.

Background: To spare important anatomical structures from damage during treatment of cystic odontogenic lesions, decompression has become a conservative alternative to enucleation. Marsupialization, in combination with the use of a custom-made decompression prosthesis, is an effective method of inducing reduction and bony infill of cystic lesions of the jaw.
Methods: In this case series and review of the literature, we describe three patients with odontogenic cysts of the mandible who were treated with custom-made decompression obturator prostheses (DOP) at the Memorial Sloan Kettering Cancer Center Dental Service.

Purpose: This study aimed to evaluate odontogenic keratocysts associated with basal cell nevus syndrome (BCNS) using computed tomography (CT) and magnetic resornance imaging (MRI) including diffusion-weighted imaging (DWI) and compare them with sporadic cases.
Materials And Methods: This study investigated 17 outpatients who underwent panoramic radiography, CT, and MRI between August 2012 and January 2021. Five of these patients had BCNS had 16 odontogenic keratocysts, for which the authors recorded detailed findings.

Background: Odontogenic cysts of the jaws are pathologies that require timely recognition and management. The initial diagnosis is based on clinical and radiographic appearance and dental history. A variety of surgical treatments are used for odontogenic keratocyst (OKC) depending on the clinical and radiographic presentation.

Malignant transformation arising in the background of jaw cysts is a rare and often misdiagnosed condition, particularly when developing from residual root-derived cysts. We present a case of epithelial malignancy originating from a residual root-derived cyst in the mandible of a man around 50 years old. Histological evaluation of the sections revealed that the epithelial lining of the cystic lesion contained well-differentiated squamous cell carcinoma components.
