Quantitative and Qualitative Maxillary Jaw Bone Assessment Using Cone Beam Computed Tomography of a Diabetic Versus a Nondiabetic Sample of Egyptian Population.

Abstract

Background and purpose:Evaluation of maxillary bone is very essential for the diagnosis, treatment planning, and management of maxillofacial procedures. This study aimed to evaluate the maxillary jaw bone quality and quantity in a sample of Egyptian patients with diabetes mellitus (DM) compared to another nondiabetic sample using Cone Beam Computed Tomography (CBCT) and also to correlate between the maxillary jaw bone quality and quantity and other factors as glycated haemoglobin (HbA1c) values, disease duration, type of medication, extraction period, and gender.Methods:After approving the study protocol by the local Ethics Committee, sixteen patients with diabetes mellitus and sixteen control subjects were included in this study. Three maxillary bone measurements (alveolar ridge height, bucco-palatal dimension, and trabecular bone density) were performed on selected CBCT cross-sectional images. These measurements were performed by two radiologists once and one of them carried out the measurements twice. Results:Thisstudy demonstrated that there was no significant difference between the normal and diabetic groups regarding all maxillary measurements except for the maxillary trabecular bone density of the normal group which was statistically lower than that of the diabetic group. Maxillary trabecular bone density was correlated significantly with most of the studied variablessuch as disease duration, type of DM medication, teeth extraction period, and gender.Conclusion:Diabetes is not an absolute contraindication for any maxillofacial surgeries and each diabetic patient indicated for any maxillofacial surgery should be evaluated independentlyregarding the maxillary bone quality and quantity as well as the contributing local factors.

An appraisal of bone resorption in completely edentulous diabetic and nondiabetic patients at prospective implant site in anterior mandible using digital volumetric tomography and its correlation with glycemic control: A case–control study

“…In the present study, no subject in any group showed mean height less than the prescribed height <11 mm. Many studies have evaluated height parameter at various implant sites, some have measured it at the midline,[ 6 21 ] at edentulous sites,[ 6 32 33 34 ] some have measure it near the premolar region with inclusion of safe distance from anterior loop,[ 6 35 ] some have conducted prospective studies where implants were placed in prospectively[ 36 ] Studies which evaluated the width parameter are scarce and involve methods formulated by the researchers for standardization;[ 21 35 ] however, it must be realized that height and width are interdependent quantities but often height adjustments are done to accommodate for the necessary adequate width. The present study is unique in the sense that all the prescribed prospective implant site[ 26 ] have been measured for the height parameter.…”

“…[ 41 ] Kenawy et al ., in 2017, compared bone resorption and bone density between diabetic and nondiabetic patients and found no significant difference between bone quantity, there was decreased bone density in diabetic patients. [ 33 ] Taylor et al ., in 1998, tested and proved the hypothesis that noninsulin-dependent diabetes mellitus patients have a higher progression of residual ridge resorption. [ 42 ] the present study supports these findings as the ORI was found to be lower in diabetic patients as compared to nondiabetics.…”

Relation of Cone Beam Computed Tomography Assessment of Mandibular Bone Density to Dual Energy X-Ray Absorptiometry in Type 2 Diabetes Mellitus Patients

“…CBCT technique was used to assess the mandibular bone density related to the edentulous bounded saddle. Before performing any measurements, a precise panoramic curve was accurately drawn on a selected axial cut at approximately the mid-tooth level of the mandibular teeth (14). The inferior alveolar nerve canal was accurately traced until the mental foramen using the panoramic image.…”
