The study identified and analyzed the relationship between cone-beam computed tomography (CBCT) and markers of oxidative stress in patients with chronic generalized periodontitis (CGP) without somatic pathology and with bronchoectatic disease. 90 patients with CGP were examined, which were divided into two groups: patients with CGP without somatic pathology (n=40) and patients with CGP with comorbid pathology in the form of bronchiectatic disease (n=50). Somatically healthy persons with intact periodontal disease (n=40) were examined as a control group. Enzyme immunoassay was used to determine the levels of malondialdehyde (MDA), advanced oxidation protein products (AOPP) and total superoxide dismutase (total SOD) of all three types — Cu/Zn-SOD + Mn-SOD + Fe-SOD) in oral fluid. In patients with CGP observed intensification of oxidative stress expressed in an increase in oxidation products of lipids and proteins, as well as a decrease in antioxidant protection. Greater intensification of the process of oxidative stress and deeper changes in periodontal tissues were detected in patients with CGP with bronchiectatic disease. According to the results of correlation analysis, statistically significant, positive relationships of different strength between changes in the level of MDA, AOPP, total SOD and CBCT parameters in patients with CGP, both without somatic pathology, and with bronchiectatic disease were revealed. The revealed interrelations evidence of the influence of the intensification of the process of oxidative stress on a condition of periodontal tissues at patients with CGP. The strength of the identified relationships between most of the indicators characterizing CB CT deep periodontal lesions was greater in patients with CGP with bronchiectatic disease.

The Relationship

ABSTRACT Objectives Exact location of the inferior alveolar nerve (IAN) bundle is very important. The aim of this study is to evaluate the relationship between the mandibular third molar and the mandibular canal by cone-beam computed tomography. Study design This was a cross-sectional study with convenience sampling. 94 mandibular CBCTs performed with CSANEX 3D machine (Soredex, Finland) and 3D system chosen. Vertical and horizontal relationship between the mandibular canal and the third molar depicted by 3D, panoramic reformat view of CBCT and cross-sectional view. Cross-sectional view was our gold standard and other view evaluated by it. Results There were significant differences between the vertical and horizontal relation of nerve and tooth in all views (p < 0.001). Conclusion The results showed differences in the position of the inferior alveolar nerve with different views of CBCT, so CBCT images are not quite reliable and have possibility of error.

Objective: This study aimed to investigate the prevalence of apical periodontitis (AP) in patients with type II diabetes mellitus (DM) with either optimal glycemic control (OGC) or poor glycemic control (PGC) compared with nondiabetics using cone beam computed tomography (CBCT). Subjects and Methods: The periapical status of 75 teeth with adequate root canal treatment performed at least 1 year ago that could be visualized in the field of view of CBCT images of 43 DM patients (29 females, 14 males) was compared with a control group consisting of 162 teeth of 86 nondiabetics (56 females, 30 males). In addition, the DM group was divided into subgroups according to the patients’ mean glycated hemoglobin level as either having OGC or PGC. The periapical status of the teeth was evaluated using the CBCT periapical index (CBCTPAI), and AP was diagnosed as a CBCTPAI ≥1. χ2, Fisher’s exact test, and independent-samples t tests were used for the statistical analysis, and p < 0.05 was considered significant. Results: Significant differences between the DM group and the control group were observed (p< 0.05) in terms of AP (the frequencies of both CBCTPAI ≥1 and CBCTPAI ≥3) and the frequency of cardiovascular disease, while there were no significant differences between the DM subgroups (p > 0.05). Conclusion: The prevalence of AP and severe bone destruction in periapical tissues was significantly higher in the DM patients compared with the nondiabetic patients.

Aim. The aim of the present study was to examine the relationship between articular eminence inclination, height, and thickness of the roof of the glenoid fossa (RGF) according to age and gender and to assess condyle morphology including incidental findings of osseous characteristics associated with osteoarthritis (OA) of the temporomandibular joint (TMJ) using cone beam computed tomography (CBCT).Materials and Methods. CBCT images of 105 patients were evaluated retrospectively. For articular eminence inclination and height, axial views on which the condylar processes were seen with their widest mediolateral extent being used as a reference view for secondary reconstruction. Condyle morphology was categorized both in the sagittal and coronal plane.Results. The mean values of eminence inclination and height of males were higher than those of females (P<0.05). There were significant differences in the RGF thickness in relation to sagittal condyle morphology. Among the group of OA, the mean value of the RGF thickness for “OA-osteophyte” group was the highest (1.59 mm), whereas the lowest RGF values were seen in the “OA-flattening.”Conclusion. The sagittal osteoarthritic changes may have an effect on RGF thickness by mechanical stimulation and changed stress distribution. Gender has a significant effect on eminence height (Eh) and inclination.

Objectives. To assess the relationship between dental follicle width and maxillary impacted canines’ descriptive and resorptive features with three-dimensional (3D) cone-beam computed tomography (CBCT). Methods. The study comprised 102 patients with cone-beam computed tomography 3D images and a total of 140 impacted canines. The association between maxillary impacted canine dental follicle width and the variables of gender, impaction side (right and left), localization of impacted canine (buccal, central, and palatal), and resorption of the adjacent laterals was compared. Measurements were analyzed with Student’s t-test, Kruskal-Wallis test, and Mann–Whitney U statistical test. Results. According to gender, no statistically significant differences were found in the follicle size of the maxillary impacted canine between males and females (p>0.05). Widths of the follicles were determined for the right and left impaction sides, and no statistically significant relation was found (p>0.05). There were statistically significant differences between root resorption degrees of lateral incisors and maxillary impacted canine follicle width (p<0.05). Statistically significant higher follicle width values were present in degree 2 (mild) resorption than in degree 1 (no) and degree 3 (moderate) resorption samples (p<0.05). Conclusions. No significant correlation was found between follicle width and the variables of gender, impaction side, and localization of maxillary impacted canines. Our study could not confirm that increased dental follicle width of the maxillary impacted canines exhibited more resorption risk for the adjacent lateral incisors.

Background Dental caries can be affected or altered by the body’s oxidant / antioxidant balance and oxidative stress. Aim/Hypothesis To examine the relationship between dental caries and Total Oxidant Status (TOS), Total Antioxidant Status (TAS), and Oxidative Stress Index (OSI). Design The study group consisted of 52 children with dental caries (DMFS/dfs ≥ 5), and the control group consisted of 42 healthy children (DMFS/dfs = 0). The saliva samples, unstimulated and mid-morning, were collected from all children. Participants’ saliva samples were acquired by spitting for 5 minutes, after which the samples were frozen and stored at 4 ° C and kept at -80 ° C until analysis. NCSS (Number Cruncher Statistical System) 2007 (Kaysville, Utah, USA) was used for the statistical analysis. Results TOS of the patient group cases were statistically significantly higher than those of the control group (p=0,004; p<0,01). OSI values of the patient group cases were statistically significantly higher than those of the control group (p=0,008; p<0,01). Conclusion OSI and TOS as markers of oxidative stress levels were found to be significantly higher in the group of patients with dental caries than in the healthy group.
