Öğe A retrospective comparative fractal and radiomorphometric analysis of the effect of 3 generations of anti-epileptic drugs on the mandible(Elsevier Science Inc, 2023) Temur, Katibe Tugce; Magat, Guldane; Ozcan, SevgiObjective. The present study investigated the possible impacts of anti-epileptic drugs (AEDs) on trabecular and cortical bone in the mandible.Study Design. Fractal dimension (FD) and the radiomorphometric parameters of mandibular cortical width (MCW), panoramic mandibular index (PMI), and mandibular cortical index (MCI) were assessed on 497 dental panoramic radiographs (DPRs) of patients in the case group and controls. AEDs were compared according to 3 generations, duration of use, and patient age and sex.Results. FD of the angle and body of the mandible and MCW were significantly lower in the case group than in the control group (P < .001). FD values in the ramus and angle were lower in first-generation and third-generation AEDs than in second-generation drugs (P < .011). FD in the mandibular body was lower in first-generation and second-generation AED users than in third-genera-tion drugs (P = .017). Drug use for at least 1 year resulted in significantly lower values for all FDs and MCW values and more class 3 MCI assessments than short-duration use, but PMI was higher with more than 1 year of AED use (P < .020). Age and sex had no significant effects.Conclusions. AEDs caused significant changes in bone compared with controls in some FD values, MCW, and MCI. The effect of drug generation is pronounced in trabecular bone. Anti-epileptic drug use for more than 1 year had a greater effect than short-term use.

This study aimed to categorize the impacted mandibular teeth in a group of adult patients by two different classifications and determine their relationship with pathological changes. Material and Methods: Preoperative panoramic radiographs of 1165 patients who had previously undergone removal of impacted mandibular third molar teeth were analyzed. Impacted teeth were categorized according to the Winter and Pell & Gregory classifications. Associated pathological findings included caries in adjacent molar teeth, pericoronal radiolucencies, possible cyst or tumor finding, and root resorption in adjacent molar teeth. Results: The most common pathological findings associated with impacted mandibular third molars were pericoronal radiolucency (33.7%) and caries in second molars (24.9%), respectively. Distal decays were detected in second molars adjacent to those in mesioangular, Class I, and Level A positions. Radiolucency was found most frequently in those in vertical, Class II, and Level B positions (p<0.001). Cyst and tumor were found to be most common in those in horizontal, Class III, and Level C positions (p <0.001). Finally, resorption was found to be most common in impacted teeth in the horizontal and Class II positions (p<0.001). Discussion: Considering the positions of impacted mandibular third molars may provide an estimate of the possible future pathologies. This study may provide dentists and oral and maxillofacial surgeons with guiding findings in deciding on prophylactic removal of impacted teeth.Öğe Can tooth color be used as part of caries risk assessment? A cross-sectional study Tooth color and dental caries burden(Bayrakol Medical Publisher, 2021) Hatipoglu, Omer; Maras, Edanur; Temur, Katibe TugceAim: This study aimed to investigate whether the colors of the maxillary central incisor (MCl) and the maxillary first premolar (MPl) can serve as indicators to estimate dental caries risk. Material and Methods: A total of 140 healthy dentistry students aged 18-25 years participated in this cross-sectional study. The MCl and MPl were polished with a polishing brush for 20 seconds. After polishing, in room light, L.*, b*, chroma, and hue values were measured from three different regions of the teeth with the VITA Easyshade spectrophotometer device. After color evaluation, dental caries burden was determined according to the Decayed, Missing, and Filled Teeth (DMFT) index. A questionnaire addressing demographic features, dietary habits, and smoking habits was also administered. Spearman's correlation tests and multiple linear regression analyses were conducted. Result No significant correlation was found between DMFT scores and L* values. The DMFT index was positively correlated with the a*, b*, and chroma of the MCl but was negatively correlated with hue. in terms of the MPl, no significant correlation was detected between DMFT and color parameters. Smoking and tooth-brushing had significant effects on MCl b* and chroma and on MCI a*, b*, and chroma, respectively. No significant effect of confounding factors was observed on MPl L*, a*, b*, chroma, or hue. Discussion: This study concludes that dental caries risk may be predicted with color values of the MC1. However, the same does not apply for the MPl. The ability to predict dental caries by evaluating the color of the MC1 shows the potential for color to be used as a part of caries risk assessment.Öğe Evaluation of fractal analysis and radiomorphometric measurements of mandibular bone structure in bruxism and non-bruxism paediatric patients(Springer, 2024) Onsuren, Asli Sogukpinar; Temur, Katibe TugceObjectives The goal of this examination was to compare the impact of probable sleep/awake bruxism on the mandibular trabecular bone structure by fractal analysis (FA) with digital panoramic radiograph (DPR) and radiomorphometric measurements in paediatric patients with bruxism. Methods The examination included 130 participants with 63 patients with probable sleep/awake bruxism and 67 control groups. Bilateral regions of interest (ROI) in three regions were examined as ROI1: mandibular ramus, ROI2: mandibular angulus, ROI3: anterior to the molar teeth. Radiomorphometric measurements were taken of the mandibular cortical width (MCW), panoramic mandibular index (PMI), and mandibular cortical index (MCI). p < 0.05 was approved for statistical significance. Results The ROI-1, ROI-2, and ROI-3 values were defined to be statistically significantly high in the bruxism group (p < 0.05). No significant difference was found between the groups in the other values (p > 0.05). There was no difference in the age and gender for any of the parameters (p > 0.05). Conclusion In children and adolescents, the mandibular trabecular bone can be affected by bruxism. FA can be used as an auxiliary method for finding the mandibular trabecular differences of patients with bruxism in paediatric dentistry just as it can for adults.Öğe Evaluation of mandibular trabecular bone by fractal analysis in pediatric patients with hypodontia of the mandibular second premolar tooth(Bmc, 2024) Temur, Katibe Tugce; Magat, Guldane; Cukurluoglu, Aykagan; Onsuren, Asli Sogukpinar; Ozcan, SevgiBackground It is still unclear whether the trabecular structure of the jaw is different in individuals with hypodontia than in those without hypodontia; this is important for clinicians. The aim was to determine whether the mandibular trabecular bone structure of children and adolescents with hypodontia differs from the control group by using the fractal analysis (FA) method in this study. Methods A total of 138 panoramic radiographs of 69 cases and 69 control subjects (mean age 13.2 +/- 10.1) were evaluated. The age and gender of subjects in the case and control groups were matched. Three regions of interest (ROIs) were selected from the panoramic radiographs. ROI1 refers to the center of the ramus rising above the mandibular foramen. ROI2 refers to the area between the apical level of the mandibular molar and the upper border of the mandibular canal. ROI3, the missing tooth region, refers to the apical third of the mesial side of the erupting or fully erupted permanent mandibular first molar. Mann-Whitney U and Wilcoxon tests were used. p < 0.05 was accepted for the significance value. Results The mean fractal dimension (FD) values of ROI1, ROI2, and ROI3 were 1,25, 1,20, and 1,13, respectively. The means FD values obtained from the ramus region were higher than the other regions (p < 0.05). The FD values did not differ significantly according to gender and age (p > 0.05). The FD values of the case group were lower than the control group for ROI3 (p < 0.05). Conclusion The results of this study showed that the mandibular trabecular bone quality of pediatric patients with one missing tooth was different from the healthy group. The difference in the mean FD values from the ROIs indicates that the ramus has a denser structure than the mandibular corpus. Clinicians should factor this into their dental treatment planning process.Öğe Evaluation of the effect of sickle cell disease on the mandibular bone of children and adolescents by image texture and radiomorphometric analysis(Springer, 2023) Temur, Katibe Tugce; Magat, Guldane; Yilmaz, Melis; Ozcan, SevgiObjectivesSickle cell disease (SCD) can cause osteoporotic changes in the jaw bones. In this study, it was aimed to evaluate possible bone changes using fractal analysis (FA) and morphometric analyses in dental panoramic radiographs of children and adolescents diagnosed with both homozygous and heterozygous forms of SCD.MethodsSixty-five individuals (33 SCD, 32 controls) aged 6-17 years were included in the study. Four separate areas of interest (ROI) were selected for the right and left sides of all panoramic radiographs, and the FA value of the ROIs was calculated. Mandibular cortical width (MCW), panoramic mandibular index (PMI) and mandibular cortical index (MCI) and were evaluated. Data were statistically analyzed and p < 0.05 was accepted for statistical significance.ResultsFractal values of right and left ROI1 (the center of the mandibular angle.) and ROI4 (the cortical bone), and right ROI2 (the middle of the mandibular ramus) were statistically lower in the case group (p < 0.05). Right ROI2 and ROI4 fractal values of individuals in the case group were lower than those on the left side (p < 0.05). While MCI categories did not differ from the case-control group (p > 0.05), PMI and MCW values were lower in the case group (p < 0.05). All evaluated parameters did not differ according to age and gender (p > 0.05).ConclusionThe results of this study showed that SCD affects the mandible. FA, MCW and PMI parameters can be used to detect early osteoporotic changes in the disease.Öğe Incidental dental anomalies and jawbone pathologies in Turkish pediatric patients of the Eastern Mediterranean region(Bayrakol Medical Publisher, 2021) Temur, Katibe TugceAim: The present study aimed to examine the prevalence of incidental dental anomalies and jawbone pathologies in a group of pediatric patients from the Eastern Mediterranean region. Material and Methods: Sociodemographic data of the patients were extracted from digital automation records. Moreover, panoramic radiography archives of pediatric patients, who applied to the School of Dentistry, Sutcu Imam University for examination for any reason, were scanned so that dental anomalies and jawbone pathologies were determined. The study was conducted by an oral and maxillofacial radiologist. Results: The study examined the panoramic radiographs of 1432 pediatric patients aged 5-17 years. The most prevalent incidental dental anomaly and jawbone pathology were impacted teeth (4.8%) and periapical lesion (21.8%), respectively. Nevertheless, while the least prevalent incidental dental anomalies were ectopic teeth (0.2%), taurodontism, and macrodontia (0.6%), we found the least prevalent pathological finding to be odontoma (0.2%). Discussion: This retrospective study on a group of pediatric patients from the Eastern Mediterranean region revealed that the most prevalent dental anomaly was impacted teeth, while the most prevalent pathology was periapical lesion. Ultimately, in the early detection of such findings, all regions should be routinely evaluated in panoramic radiographys.Öğe The location of the mandibular foramen as a guide in mandibular block anesthesia in children by age: A radiographic analysis(Ondokuz Mayis Universitesi, 2022) Temur, Katibe Tugce; Soğukpinar Önsüren, AslıKnowing the correct location of the mandibular foramen (MF) is a significant factor in the success of inferior alveolar nerve block (IANB). The primary clinical guide for this anesthesia in children with continued growth and development may be the location of MF. The present study was carried out retrospectively on panoramic radiographs of children aged 5-14 years. Three linear measurements were performed on panoramic radiographs to evaluate the distance of the MF to the occlusal plane (OP), anterior border of the ramus (ABR), and mandibular base (MB). The participants’ ages were divided into five groups: (G1) 5-6 years, (G2) 7-8 years, (G3) 9-10 years, (G4) 11-12 years, and (G5) 13-14 years. The results revealed a statistically significant increase in the mean values from G2 to G4 in all measurements. However, it was determined that there were no statistically significant differences between G1 and G2 and between G4 and G5 by the mean measurement values, respectively. Besides, the results of the measurements did not significantly differ by sex. Overall, it was concluded that MF was slightly below OP under 8 years of age and moves in the poster superior direction until the permanent dentition period. This result may guide clinicians in IANB in children. © 2022 Ondokuz Mayis Universitesi.

This research seeks to investigate the impact of maternal oral and dental health on the incidence of P-PROM and its association with inflammatory markers in the blood. Methods: This study adopts a prospective case-control design methodology. The study involved 70 women diagnosed with P-PROM and delivered by an obstetrician and 79 women who had healthy deliveries with no prenatal complications. The values for DMFT (Number of decayed, missing and filled teeth) index, Gingival Index (GI), Plaque index (PI), Pocket depth (PD), Clinical attachment loss (CAL) and medical history were recorded. Mann-Whitney U test and hierarchical binomial logistic regression analysis were applied. It was considered statistically significant at p < 0.05. Results: The case group’s DMFT, PI, GI, PD values were statistically significantly higher than the control group (p < 0.001). There was no relationship between DMFT, GI, PD, CAL and inflammatory blood markers (p > 0.05). In the regression analysis for possible risk factors that may be effective in P-PROM, oral and dental health parameters were the most effective. Conclusions: Oral and dental health of women with P-PROM was found to be worse than that of the control group. Oral and dental health may be a potential risk factor that may contribute to adverse pregnancy outcomes associated with P-PROM. © The Author(s) 2024.
