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.

Objective: The purpose of the present study was to investigate the articular eminence inclination and height according to age and gender in patients with temporomandibular joint (TMJ) dysfunction and healthy controls using cone beam CT (CBCT). Methods: The measurements were performed on CBCT records of 52 TMJ dysfunction patients (11 males and 41 females) and 41 control patients (17 males and 24 females). The eminence inclination and height were measured on the CBCT images. Results: The eminence inclination and height values were higher in males than in females in both TMJ dysfunction patient and control groups; however, these differences were not statistically significant (p . 0.05). While no statistically significant differences were found in the eminence inclination and height values between the age groups (p . 0.05) in the TMJ dysfunction patient group, there were statistically significant differences in the control group. The eminence inclination was highest between the ages of 21 and 30 years and showed a decrease after the age of 30 years. Additionally, the eminence inclinations of the control patients were statistically higher than those of the TMJ dysfunction patients. Conclusion: There were no statistically significant differences in eminence inclination and height according to gender. The eminence inclination reaches its highest value between the ages of 21 and 30 years and shows a decrease after the age of 31 years in healthy patients. The eminence inclination was steeper in healthy control patients than in patients with TMJ dysfunction.

Objectives: 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. Methods: 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. Results: 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 caninepremolar 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. Conclusions: 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. Dentomaxillofacial Radiology (2012) 41, 152-158. doi: 10.1259/dmfr/10586700 Keywords: bone cyst; computer-assisted three-dimensional imaging; panoramic radiography; cone beam computed tomography; salivary glands Introduction Stafne bone defect (SBD) was first described by Stafne in 1942, who reported 35 asymptomatic unilateral radiolucent cavities in the posterior region of the mandible. Lesions were located between the mandibular angle and the third molar, below the inferior dental canal and above the mandibular base. 1 Many other terms have been used to describe this entity, including aberrant or ectopic salivary gland; static, latent or idiopathic defect, cavity or cyst; mandibular salivary gland inclusion; lingual mandibular bone cavity, concavity or depression; and Stafne cyst, defect or cavity. [2][3][4][5][6][7][8][9][10][11] The posterior lingual variant has an incidence of between 0.10% and 0.48% when diagnosed radiologically. However, some cadaver studies have revealed that the incidence of the lesion may be as high as 6.06%. The age range is quite wide, although there is a clear predilection for males in the fifth or sixth decade. 3,6,9 When the term SBD is found in the literature, it usually refers to the posterior lingual variant. The anterior lingual variant is seven times less frequent than the posterior and is usually located between the incisor and the premolar areas, above the insertion of the mylohyoid muscle. 2,11When reviewing the literature regar...

Objectives: The purpose of the present study is to determine the nature of the complaints that bring patients to our clinic and to what degree these complaints affect their quality of life (QoL). We also aimed to determine any associations between gender, education or harmful habits and each patient's oral health-related quality of life (OHQoL). Methods: A total of 1090 patients, consisting of 651 females (59.7 %) and 439 males (40.3 %), were included in this study. Of these patients, 220 constituted healthy controls. Two patient-centered outcome measures, the 14 item OHIP-14 and the 16 item OHQoL-UK measures were used. Results: Most of the patients presented with toothache and caries (50.1 %), 11.2 % had suffered tooth loss and had denture needs, 9.2 % had periodontal problems, 1.8 % had temporomandibular joint (TMJ) disorders, 3.8 % had buried third molars, 2.4 % had orthodontic and aesthetic disorders, 1.3 % had suffered injury due to trauma, and 20.2 % came only for control checkups. OHQoL was best in the control group and the worst in patients who had suffered trauma. In addition, we noted correlations between gender, education and harmful habits, and that of the patient's oral health-related quality of life. Conclusion: According to our results, OHQoL is associated with the oral complaints of patients. Furthermore, OHQoL may not only be associated with the oral health status of patients, but factors such as gender, education and harmful habits may also play a role.

Objectives: The aim of this study was to determine the prevalence of root dilaceration in a Turkish dental patient population with respect to sexes and dental localization in relation between sex and this anomaly. Study Design: A retrospective study was performed using periapical radiography of 2,124 patients ranging in age from 15 to 65. All data (age, sex and systemic disease or syndrome) was obtained from the files. These patients were analyzed for root dilaceration. Descriptive characteristics of sexes, jaws, and dental localization were recorded. The Pearson chi-squared test was used. Results: Of 2,251 patients, 214 (9.5%) had root dilaceration. Root dilacerations were determined in 276 (4.3%) of 6386 teeth belong to 2251 patients. Anomalies were found in 9.8% of males compared with 9.3% of females. However, this difference was not statistically significant (p>0.05). Root dilacerations were similarly distributed between 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%), maxillary first molars (6.7%). Root dilaceration was not detected in maxillary central incisors, mandibular central incisors and mandibular lateral incisors. Conclusion: According to our results, root dilaceration is an uncommon developmental anomaly which mostly occurs in the posterior teeth that is not also possible to have trauma. The radiographic diagnosis of this anomaly is important before surgery and orthodontics treatment, but firstly endodontic treatment.
