    ABSTRACT: Objectives: Orthodontists usually evaluate the mid-palatal sutural opening with occlusal radiography. The purpose of this paper is to evaluate the sutural opening with ultrasonography (USG) in a series of patients undergoing RPE. Methods: The study included 87 USG images and 87 occlusal radiographies from 29 healthy patients (mean age, 13.9 years; range, 11-20 years; 12 boys, 17 girls) who required RPE treatment. The sutural opening was assessed with USG and the amount of sutural expansion as mesio-distal length was measured immediately after appliance practice (T0), 10 turns (T1), and 20 turns (T2) during the expansion period. Sutural expansion evaluated by occlusal radiographies was scored at every stage. Measurements obtained by USG and scores observed in the occlusal radiographies were compared by nonparametric Kendall's tau test. Results: Both USG and radiographic images revealed normal anatomical structure during pre-expansion (stage T0). On USG, sutural expansion was seen in 19 patients at stage T1. There was no expansion at this stage in 10 patients. At stage T2, on USG and radiography, an increase in the amount of expansion was observed in 19 patients with sutural expansion at stage T1 and sutural expansion was observed in 5 patients without sutural expansion at stage T1. No expansion was observed at both stages T1 and T2 in 5 patients. USG measurements and occlusal scores in both T1 and T2 turns showed statistically significant correlation (p<0.001). Conclusion: The results indicate that USG might be a useful method to assess mid-palatal sutural opening in patients undergoing RPE.

    ABSTRACT: Heterotrophic soft tissue calcification occurs with the deposit of calcium salts in soft tissue rather than bone. The aim of this report is to describe cone-beam computed tomographic (CBCT) and ultrasonographic (US) findings of 2 cases of soft tissue calcifications that were initially diagnosed as submandibular or parotid sialolithiasis. Multiple soft tissue calcifications were evaluated by panoramic radiography, CBCT imaging, and US imaging in a 50-year-old male patient and a 30-year-old male patient. Calcifications were detected in the soft tissue of the submandibular area at axial, coronal, and multiplanar reformatted examinations and were prediagnosed as sialolithiasis. US examination was conducted to determine the complete relation between the soft tissues and the calcifications. In conclusion, high-resolution dental volumetric tomography with a low radiation dose is the optimal diagnostic tool to analyze the skeletal structure of the maxillofacial region in 3 dimensions. However, it is not sufficient to examine the soft tissues. US imaging is a useful diagnostic tool to evaluate the relation between the soft tissues and the calcifications in the submandibular area.

    ABSTRACT: Objective: This study was conducted to describe the frequency of diabetes in dental patients, and to compare three different screening methods: the random finger plasma glucose (RFPG) test, the Finnish diabetes risk score (FINDRISC) survey and a special clinical guideline developed for dental patients. Methods: The study design was cross-sectional, descriptive and comparative. The data were collected between August 2011 and February 2012. A total of 702 dental patients participated in this study. The screening tools were RFPG, FINDRISC and a clinical guideline. Data were analyzed using the Chi-squared test, the t test, analysis of variance, and the Pearson correlation test. Results: The frequency of diabetes was 8.3% for the participants. The prevalence of participants at risk for undiagnosed diabetes was 20.1% according to the RFPG test, 29.9% according to the FINDRISC, and 29.8% according to the clinical guideline. Correlation analysis showed a significant positive correlation between the screening methods (p<0.001 for each). Conclusion: The overall frequency of diabetes was 8.3%. It was found that the three screening methods used in this study were statistically similar. However, FINDRISC and clinical guideline as the questionnaire screening tools indicated a little larger group than RFPG with respect to diabetes risk.

    ABSTRACT: Objective The aim of this study was to investigate the frequency of ponticulus posticus (PP) using cone beam computed tomography (CBCT) and to describe the radiological characteristics of the detected cases. Study Design The presence and types of PP were investigated on 730 CBCT images. Results PP was found in 17.4% (127) of the 730 CBCT scans. Of these 127 patients, 79 (10.8 %) had bilateral PP and 48 (6.6 %) had unilateral PP. Male predominance was found with a prevalence of 19.5% (54 of 277) and female prevalence was 16.1% (73 of 453). The prevalence of PP increased with age; the highest prevalence of PP was seen in those who were 49 to 81 years of age. Conclusions This study shows that PP is not an uncommon anatomical variation and natural incidental finding on CBCT.

    ABSTRACT: Objective: The aim of this study was to determine and compare the reliability to accomplish of common mandibular landmarks and to determine the incidence of incisive canals, anterior looping, and lingual foramina in children from panoramic and CBCT images. Design: Panoramic and CBCT images from 100 children and adolescent patients were randomly selected. In order to grade the visibility of mandibular anatomical landmarks, a four-point rating scale was used. Results: In panoramic images, the mandibular canal could be observed in 92.5% of cases, with good visibility in 12.0%. The mental foramen could be observed in 44.5% of cases, while none had good visibility. Anterior looping of the mental nerve was present in 16.5% of the cases, and none had good visibility. An incisive canal could be identified in 22.5% of cases, with only 1.5% showing good visibility. The lingual foramen could be visualized in 61.0% of cases, with good visibility in 6%. In CBCT images, the mandibular canal, the mental foramen, and the lingual foramen could be observed in 100% of the cases, with good visibility in 51.0%, 98.5%, and 45.0% of cases, respectively. Anterior looping of the mental nerve was present in 26% of cases, with 2% having good visibility. An incisive canal could be identified in 49.5% of cases, with only 75% showing good visibility. Conclusions: This study confirms the applicability of CBCT images to visualize critical structures in children.

    ABSTRACT: Background/purposeDuring root canal therapy, third roots of mandibular first molars (MFMs) provide an important route for bacterial leakage that can lead to root canal treatment failure and the need for additional surgical intervention. Therefore, the aim of this study was to investigate root and canal morphology of permanent MFMs in a Turkish population using cone beam computed tomography (CBCT).Materials and methodsWe collected 533 CBCT images of MFMs; 81 subjects had unilateral molars and 226 subjects had bilateral molars. The following observations were made: (1) root number; (2) number of canals per root; and (3) root canal configuration in each root using Vertucci's classification with additional modifications.ResultsThe frequency of three-rooted MFMs was 2.4%. Of the 533 MFMs examined, two canals were present in 0.4%, three canals in 69.9%, four canals in 28.7% and five canals in 1.0%. The most common canal morphology in the mesial roots was Vertucci type IV (59.5%), followed by type II (32.8%). The distal roots showed predominantly Vertucci type I (74.7%), followed by types II (12.3%) and IV (9.7%).Conclusion Our results showed a low frequency (2.4%) of three-rooted MFMs in a Turkish population. This close to the average root number among people of European descent. Root and canal configurations of MFMs were consistent with previously reported data. CBCT may be recommended as an effective diagnostic modality for identifying root and canal configuration.

    ABSTRACT: The aim of this study was to describe agenesis of permanent teeth, excluding the third molars, in a sample of children in Eastern Turkey. This retrospective study assessed 1,291 digital orthopantomograms (OPT) (678 males and 613 females), taken at the Faculty of Dentistry, Ataturk University, Erzurum. The chi-square test was used to compare maxillary and mandibular hypodontia in males and females. Eighty children were found to have at least one tooth absent from their permanent set of teeth. The prevalence of tooth agenesis was 6.2%. A total of 135 permanent teeth were missing as a result of the congenital condition. Tooth agenesis was found more frequently in females than in males. Although there was no significant difference between genders in the prevalence of hypodontia among the children (p>0.05), the difference between genders in children who had congenitally missing teeth (CMT) reached a statistically significant level (p<0.05). When hypodontia in a Turkish paediatric population was compared to other populations, the characteristics were found to be similar to the Western population. However, the population in Eastern Turkey differs from the population in Asia, where there is less incisor tooth agenesis and more second molar tooth agenesis.

    ABSTRACT: The aim of this study was to investigate whether or not the Greulich-Pyle (GP) method is adequate for Turkish children. A group of 767 individuals (425 girls and 342 boys) between 7 and 17 years were studied. Bone age (BA) from plain radiographs of left hands and wrists by GP standards was estimated. The total mean differences between BA and chronological age (CA) for girls and boys were found to be 0.20 and -0.13 years, respectively. There were significant differences between BA and CA in age groups 7-, 8-, 10-, 11-, 12-, 13-, 15-, and 16-year-olds for girls and 7-, 10-, and 12-year-olds for boys. The results of this study suggest that the mean differences between BA and CA are low enough to be of no practical significance, and thus, for the time being unless any other methods will be proved more useful, this method could be used in all age groups.

    ABSTRACT: The aim of this study was to investigate the frequency of Stafne bone defect (SBD) and to describe the clinical and radiological characteristics of detected cases. A retrospective study was performed using panoramic radiographs from 34 221 patients undergoing dental treatment in the Department of Oral and Maxillofacial Radiology at Erciyes University and Ataturk University, Turkey. After finding an image compatible with SBD in the radiographs, multislice CT (MSCT) on seven patients and cone beam CT (CBCT) on six patients were performed to confirm the diagnosis. Of the 34 221 patients, 29 (0.08 %) had SBDs, of whom 4 were female (13.8%) and 25 were male (86.2 %). The age range of patients with SBD was 18-77 years (mean age 49.6 years). SBD was found in the lingual molar region in 28 patients and in the lingual canine-premolar region of the mandible in 1 patient. The contour of the concavities on CT images (MSCT and CBCT) was detected. The MSCT revealed glandular tissue within the defects. According to our results, SBD is an uncommon anomaly. Examination of MSCT images supports the presence of aberrant submandibular glands within these mandibular defects, suggesting that pressure from submandibular gland tissue had caused the SBD, as generally thought. Both CBCT and MSCT can provide adequate support for the detection of SBDs. The CBCT could be suggested as the most suitable non-invasive diagnostic modality for this bony configuration of the mandible since it provides a lower radiation exposure dose than MSCT.

    ABSTRACT: The purpose of this study was to investigate the relationship between median rhomboid glossitis (MRG) and Candida and bacteria species, prevalence and possible association with age, gender, smoking, denture wearing, and diabetes mellitus. Tongue examinations were performed on 4244 consecutive patients. Of all the examined patients, 30 diagnosed with MRG were selected as the study group and another 30 patients were selected as the control group, and these 2 groups were compared in terms of age and gender. Tongue cultures from these 60 patients were subjected to bacterial and mycological examinations. MRG frequency was detected to be 0.7%. In mycological examination, Candida species were determined in 90.0% of the MRG patients and in 46.6% of the control group. This difference was statistically significant. Multivariate logistic regression indicated that diabetes mellitus and 20-39 years of age were significantly related to MRG. However, the association between MRG, gender, smoking, and 40-69 years of age was not statistically significant. It was determined that although there was a significant association between MRG, Candida and diabetes mellitus, the possible risk factors such as gender, smoking, and denture wearing for oral candidiasis were invalid for MRG.

    ABSTRACT: Rhabdomyosarcoma (RMS), a tumor of skeletal muscle origin, is the most common soft tissue sarcoma encountered in childhood and adolescence. The common sites of occurrence are the head and neck region, genitourinary tract, retroperitonium, and, to a lesser extent, the extremities. In the head and neck region, the most commonly affected sites are the orbit, paranasal sinuses, soft tissues of the cheek, and the neck. RMS is relatively uncommon in the oral cavity, and the involvement of the jaws is extremely rare. Here, we report a case of oral RMS in a 13-year-old child and describe the clinical, radiological, histopathological, and immunohistochemical findings.

    ABSTRACT: The aim of this study was to investigate the frequency and characteristics of mesiodens among a group of orthodontic patients in Turkey. A retrospective study was performed using panoramic radiographs of 3,351 patients ranging in age from 8 to 16 subjected to dental treatment in the Department of Oral and Maxillofacial Radiology and Department of Orthodontics (Erzurum, Turkey) between 1996 and 2008. All medical and demographic data (age and sex) were obtained from the files. Descriptive characteristics of mesiodentes, including number, shape, position, complication caused by mesiodens and treatment were recorded. The Chi-squared test was used. Results show that the frequency of mesiodens was 0.3% with the ratio of boys (6 cases) to girls (4 cases) being 1.5:1 and this was not statistically significant (P>.05). Of the 10 children, 8 (80.0%) had 1 mesiodens and 2 (20.0%) had 2 mesiodentes bilaterally to midline. Of the 12 mesiodentes, 8 (66.7%) were fully impacted, 7 (58.3%) in a vertical position and 9 (75.0%) conical shape. The most common complication caused by mesiodens was delayed eruption of the permanent incisors in 4 cases (40.0%). The frequency of mesiodens in Turkish orthodontic patients was found to be 0.3% and more frequently in males with the ratio being approximately 1.5:1. Most of the mesiodentes were in conical shape (75.0%). Sixty-seven percent of the cases were fully impacted.

    ABSTRACT: The aim of this study was to investigate whether or not the Nolla method is appropriate for Turkish children for the determination of the dental age (DA). A group of 719 children between the ages of 6 and 18 years were included in the study. DAs from orthopantograms by the Nolla method were estimated. The results obtained were compared with chronologic age (CA). Paired t and the Wilcoxon tests were performed. Both genders were underestimated in dental maturity when compared with the reference samples in total (-0.3 years) (p<0.01). The differences in girls were statistically significant in total and in all groups except for 7-7.9. The differences in boys between the CAs and DAs were not statistically significant in total and in all groups except for 7-7.9 and 8-8.9. Although the accuracy of this method was suitable for boys, according to our findings, it was not suitable for girls.

    ABSTRACT: The aim of this study was to determine the prevalence and characteristics of pneumatized articular eminence (PAT) by cone beam CT (CBCT) and to present a review of the PAT literature. A retrospective study was performed using sagittal and coronal CBCT images of 514 patients in the Department of Oral and Maxillofacial Radiology, Ataturk University, Turkey. Age and gender were recorded for all patients and, for the cases of PAT, laterality and types were also recorded. The χ(2) test was used. Of the 514 patients, 41 (8.0%) had PAT, of whom 25 were female (61.0%) and 16 were male (39.0%). This difference was not statistically significant (P > 0.05). The age range of the patients with PAT was 15-62 years (mean 30.6 ± 11.4). Of the 41 patients, 31 (75.6%) had unilateral and 10 (24.4%) had bilateral PAT. 17 (41.5%) PATs were unilocular and 24 (58.5%) were multilocular. It is possible that PAT is a more frequent condition than is commonly perceived. In differential diagnosis of suspected cases or in cases for which surgical treatment is planned, panoramic radiographs should be supplemented with CBCT.

    ABSTRACT: The purpose of this study was to investigate the presence of allergy in patients with benign migratory glossitis (BMG) using patch and prick tests. Eighty patients (40 BMG and 40 healthy controls) received patch and prick tests. If at least one test result was positive, patients were considered to be allergic. The prick test was positive in 10 patients (25.0%) of the study group and in 4 patients (10.0%) of the control group. The patch test was positive in 12 patients (30.0%) of the study group and in 6 patients (15.0%) of the control group. When results of both tests were evaluated together, the study group showed a positive rate of 47.5% (n = 19), whereas the control group showed a positive rate of 22.5% (n = 9) (P = .02). Our results revealed that a combination of prick and patch tests can significantly enhance the diagnostic accuracy of predisposition of allergy in patients with BMG.

    ABSTRACT: The aim of this study was to determine the prevalence of root dilaceration in a Turkish dental patient population, considering factors such as dental localization and the relationship between the sexes in this anomaly. A retrospective study was performed using periapical radiography of 2,124 patients, who ranged in age from 15 to 65 years old. All data (age, sex and systemic disease or syndrome) were obtained from the patient files and analyzed for root dilaceration. Descriptive characteristics of sexes, jaws, and dental localization were recorded. The Pearson chi-squared test was used. Of the 2,251 patients, 214 (9.5%) were found to have root dilaceration. Root dilacerations were determined in 276 (4.3%) of 6386 teeth, belonging to a total of 2251 patients. Anomalies were found in 9.8% of males, compared with 9.3% of females, a difference that was not statistically significant (p>0.05). Root dilacerations were distributed fairly evenly between the maxilla and mandible. The most frequently root dilacerated teeth were found to be mandibular third molars (12.8%), followed by maxillary third molars (7.4%), and maxillary first molars (6.7%). Root dilaceration was not detected in maxillary central incisors, mandibular central incisors or mandibular lateral incisors. root dilaceration is an uncommon developmental anomaly which occurs mostly in the posterior teeth, which are not prone to suffer trauma. The radiographic diagnosis of this anomaly is important before surgery, and especially before endodontic treatment or orthodontic treatment.

    ABSTRACT: The objectives of the present study were to investigate the frequency of impaction, agenesis, angular position, and related pathologic changes of third molar teeth in a group of orthodontic patients. Our sample included the panoramic radiographs of 351 orthodontic patients aged 20 to 26 years (mean 22.8). The descriptive characteristics of agenesis, impaction, angular position, and pathologic changes of third molars were recorded. The chi(2) test was used for analysis. The proportion of third molar agenesis was 17.3% with no statistically significant gender differences (18.4% for women and 15.8% for men). The frequency of impacted third molars (ITMs) was 35.9% (24.2% in men and 45.0% in women; P < .05). The frequency of maxillary ITMs was 43.2% (192 of 444 teeth), and the frequency of mandibular ITMs was 56.8% (252 of 444 teeth). The position observed most often was mesioangular inclination, with a frequency of 50.0%. Only 10.4% of the ITM teeth were affected by any pathologic changes, and most of these changes were associated with the horizontal position. The present results showed that agenesis accounted for 17.3% and impaction for 35.9% of the pathologic features in this group of Turkish orthodontic patients aged 20 to 26 years of age. Mesioangular inclination was seen in 50.0%, and a small proportion (10.4%) had pathologic changes of the ITMs.
