A retrospective study of the prevalence of calcium deposits around the dens axis via cone beam computed tomography.

OBJECTIVE: This study aimed to evaluate the relationship between the presence of calcium deposits (CDs) around the dens axis and patients' age, gender, and systemic diseases. METHODS: This retrospective study was carried out by examining CBCT. Basic descriptive statistical analyses and normality tests were performed on all variables. The assumption of normality was checked using the Shapiro-Wilk method. The statistical significance level was accepted as a p-value less than 0.05. RESULTS: CDs were observed in a total of 99 (21.9%) individuals. The incidence of CDs statistically significantly increased with age (p < .01),while it didn't statistically significantly differ between genders (p = .47). 13% were systemically healthy, while 55% had hypertension. The incidence of CDs was statistically significantly higher in individuals with hypertension. CONCLUSIONS: In the presence of CDs, the patient should be referred to a medical doctor to confirm the diagnosis of CDS and prevent possible complications.

Evaluation of oral health-related quality of life in children with acute lymphocytic leukemia/acute myelocytic leukemia: A cross-sectional study.

OBJECTIVE: Chemotherapy and radiotherapy, used to treat childhood hematological malignancies (acute lymphocytic leukemia [ALL] and acute myelocytic leukemia [AML]) can negatively affect oral tissues and organs. This study aimed to evaluate the oral health-related quality of life in children with ALL/AML. MATERIALS AND METHODS: A total of 99 children, including 49 undergoing ALL/AML (41 with ALL and eight with AML) and 50 healthy volunteers, were included in this cross-sectional study. The mean age of the entire study group was 78.63 ± 34.41 months. The mean age of the ALL/AML and control groups was 87.12 ± 35.04 and 70.95 ± 34.85 months, respectively. The Simplified Oral Hygiene Index (SOHI), the Decayed, Missing, and Filled Teeth (DMFT/dmft) index, and the Turkish version of the Early Childhood Oral Health Impact Scale (ECOHIS-T) were administered to all children. The data were analyzed using SPSS software (version 22.0). The Pearson chi-square and Fisher's exact tests were used to compare demographic data. RESULTS: The age and gender distributions of the two groups were similar. According to ECOHIS-T, the children in the ALL/AML group had significantly more loss of function (eating, drinking, sleeping, etc.) than those in the control group. CONCLUSIONS: Oral health and self-care were negatively affected by childhood ALL/AML and its treatment.

Evaluation of Rheumatic Diseases Affecting the Temporomandibular Joint: A Cone Beam Computed Tomography Study and Literature Review.

INTRODUCTION: Due to the silent manifestation of temporomandibular joint (TMJ), dentists and rheumatologists may neglect treatment for this joint. AIMS: The aim of this study was to investigate the TMJ components in patients with various rheumatic diseases and to compare them with a control group based on cone beam computed tomography (CBCT) images. MATERIALS AND METHODS: This study comprised an assessment of the CBCT images of 65 patients (130 temporomandibular joints) with various rheumatic diseases (mostly rheumatoid arthritis) affecting the TMJ. Moreover, 65 patients (130 temporomandibular joints) with a similar age and gender distribution were examined as the control group. Pathologies were classified into a total of 12 types for the presence of any osseous changes in the condylar head or articular fossa or for joint space narrowing. Statistical analysis of all data was performed with SPSS version 18. The conformity of continuous variables to a normal distribution was examined by the Kolmogorov-Smirnov test. The Mann-Whitney U test was used to compare the means of two independent groups. The Pearson Chi-square test, Yates correction and Fisher's exact test were used in the analysis of categorical variables. RESULTS: The mean age of the patient and control groups was 50 ± 13 and 48 ± 16, respectively, and no statistically significant difference was found between the patient and control groups in terms of age distribution (p = 0.123). Condylar erosion, condylar flattening, subcondylar sclerosis, osteophytes, subcortical cysts, articular eminence resorption and articular eminence flattening rates were found to be statistically significantly higher in the patient group than in the control group (p < 0.05). CONCLUSIONS: Dentomaxillofacial radiologists should examine the bony components of the TMJ in patients with rheumatic diseases, and a multidisciplinary approach involving a dental specialist and rheumatologist is required.

Evaluation of demographic and clinical risk factors for high interdialytic weight gain.

Xerostomia and hyposalivation are highly prevalent in hemodialysis (HD) patients and this is effective in increased fluid intake. The aim of this study is to determine the demographic and clinical risk factors associated with high interdialytic weight gain (IDWG) in nondiabetic HD patients. In total, 52 eligible HD patients were recruited in this cross-sectional study. Patients were divided into two groups according to % IDWG: Group 1: High IDWG (≥3%) and Group 2: normal IDWG (<3%). Plasma osmolarity (POsm), unstimulated salivary flow rate (USFR), xerostomia inventory (XI), and dialysis thirst inventory (DTI) were evaluated. The mean age of the patients was 53.7 ± 15.7 years. The prevalence of xerostomia was 53.8%, and hyposalivation was in 40.3% in the patients. High IDWG was positively correlated with XI and DTI while it was negatively correlated with POsm and USFR. The area under the receiver-operating characteristics curve for POsm for high IDWG was 0.661, with sensitivity of 63.8% and specificity of 72.7% for a cut-off point of 297.4 mOsm/L. Logistic regression analysis showed that advanced age odds ratio (OR: 1.215, p = 0.019), pill burden (OR: 1.162, p = 0.031), C-reactive protein (CRP; OR: 1.308, p = 0.042), and low POsm (OR: 0.768, p = 0.046) were independently related to high IDWG. The prevalence of xerostomia and thirst was higher in HD patients with high IDWG compared to the normal IDWG group. Age, CRP, low POsm, and pill burden were independently associated with high IDWG.

The prevalence of temporomandibular disorders in chronic hemodialysis patients: a cross-sectional study.

Objective: This study aimed to investigate the prevalence of temporomandibular disorders (TMD) in patients with chronic hemodialysis and evaluate the risk factors of developing TMD.Methods: One hundred forty-six subjects were included in the study. The examination for TMD was based on the standardized Research Diagnostic Criteria for Temporomandibular Disorders. Axis I protocol was used to evaluate the prevalence of TMD sub-diagnoses.Results: The prevalence of TMD was 41.5% in hemodialysis patients and significantly higher than in the control group. The most common symptom was TMJ pain, and the most common TMD subtype was muscular type. Female patients had significantly higher TMD than males. C-reactive protein, hemoglobin, parathyroid hormone, and albumin were significantly associated with TMD.Conclusion: There was an elevated prevalence of TMD in hemodialysis patients.

The Relationship between carotid artery calcification and pulp stone among hemodialysis patients: A retrospective study.

The aim of this study was to determine the relationship between the presence of carotid artery calcification (CAC) and pulp stone (PS). A total of 60 chronic hemodialysis (HD) patients (30 CAC positive, 30 CAC negative) participated in this study. The mean age of patients was 54.7 ± 16.4 years, and 32 (53%) of them were male. CAC was defined as the presence of heterogeneous nodular opacities in the soft tissue in C3-C4 intervertebral area. Panoramic radiographs of the patients were evaluated for CAC and PS by two oral and maxillofacial radiologists. PS was evaluated in all healthy, decayed, and restored teeth except the third molar teeth, in the coronal, sagittal, and axial planes. The Statistical Package for the Social Sciences (version 20.0; SPSS, Inc., an IBM Company, Chicago, IL, USA) was used. A probability P <0.05 was considered statistically significant. The prevalence of PS in this study was 30% (18 patients) all group. A total of 1324 teeth were analyzed and PS was detected in 237 teeth (17.9%). The occurrence of PS in teeth in CAC-positive group (10 patients, 17.2% of 654 teeth) was similar to that in CAC-negative group (8 patient, 18.3% of 670 teeth). There was no statistical correlation between CAC and PS in chronic HD patients (P = 0.08). In the subgroup analysis, the presence of diabetes (P = 0.003), parathormone level (P = 0.02), calcium × phosphorus product (P = 0.04), and C-reactive protein levels (P = 0.002) were higher, and duration of HD (P = 0.03) was significantly longer in patients with CAC-positive and PS. In chronic HD patients, the presence of PS was not a strong predictor for the presence of CAC.

Thiocolchicoside associated with epileptic seizures in a chronic hemodialysis patient.

Thiocolchicoside (TCC) is a widely used centrally acting muscle relaxant. Epileptic seizures from the use of TCC are rarely reported. A 67-year-old male patient with endstage renal disease that was caused by hypertension was on maintenance hemodialysis (HD) for 22 months. He had taken TCC 8 mg capsules twice daily for four days due to painful myofascial spasm in neck and face muscles. At the end of the HD session, he had generalized tonic-clonic seizures. Epileptic seizures were brought under control with sodium valproate, and no recurrence of epileptic seizures was observed.

Evaluation of the relationship between the Demirjian and Nolla methods and the pubertal growth spurt stage predicted by skeletal maturation indicators in Turkish children aged 10-15: investigation study.

OBJECTIVE: The aim of this study was to investigate the possibility of evaluating the relationship between dental maturation and skeletal maturation without taking a hand-wrist radiogram outside of panoramic radiogram. MATERIALS AND METHODS: Panoramic and hand-wrist radiographs of 717 patients (383 girls and 334 boys), with ages ranging from 10 to 15 years, were evaluated. Dental maturity stages of the mandibular canine, first premolar, second premolar and second molar teeth were determined by Demirjian's and Nolla's methods. The skeletal maturation was determined by Fishman method and bone age was determined through the Greulich and Pyle method. RESULTS: All teeth showed positive and statistically significant correlations, the highest correlation was between the mandibular second premolar calcification stages and hand-wrist maturation stages. According to both dental age determination methods, mandibular second premolar was prominent in determining to the pubertal growth stages. CONCLUSIONS: There was a positive relationship between dental calcification stages and skeletal maturation stages, in the study population. Dental calcification stages of the second mandibular premolar showed the highest positive correlation with the skeletal maturation stages.

Garre's Osteomyelitis of the Mandible Caused by Infected Tooth.

AIM: Garre's osteomyelitis is a local thickening of the periosteum caused by a slight irritation or infection. We aimed to present the extraoral, intraoral, and radiographic findings and postoperative pursuits of two patients diagnosed with Garre's osteomyelitis. In this case report, although clinical findings indicate infection source, these clinical findings are strongly supported by cone-beam computed tomography images. In addition, it can be seen that when we have followed the case I, we have chosen the right path in treatment. CASE REPORTS: Two patients presented to our clinic due to severe swelling and facial asymmetry in the right and left mandibular region. As a result of the clinical and radiological examinations, the patients were diagnosed with Garre's osteomyelitis. Infected teeth that were responsible for the formation of Garre's osteomyelitis were extracted under antibiotic treatment in both cases. A complete improvement in postoperative control was observed in case I. On the other hand, the other case could not be followed up postoperatively. CONCLUSION: In Garre's osteomyelitis, new bone formation can occur in many pathological conditions. Therefore, it should be distinguished from other pathologies that cause new bone formation, such as Ewing's sarcoma, Caffey disease, and fibrous dysplasia.

Cone beam computed tomography imaging of superior semicircular canal morphology: a retrospective comparison of cleft lip/palate patients and normal controls.

OBJECTIVE: This study evaluated the prevalence and morphological characteristics of the superior semicircular canal (SSCC) in cleft lip and palate (CL/P) patients using cone beam computed tomography (CBCT). MATERIALS AND METHODS: CBCT images of 53 CL/P patients (28 males and 25 females) and a control group of 76 patients (42 males and 34 females) were evaluated. Retrospectively, 258 temporal bone images from 129 patients were evaluated in terms of SSCC morphology and divided into a normal pattern (0.6-1.7 mm in thickness), a papyraceous pattern (<0.5 mm), a thick pattern (>1.8 mm), a pneumatized pattern and dehiscent. The chi-squared test was used to compare differences among semicircular canal dehiscence (SSCD) patterns in the CL/P and control groups; p ≤ .05 was taken to reflect statistical significance. RESULTS: The characteristics of the SSCC were evaluated on CBCT images in patients with CL/P and controls. In total, 158 (61%) cases were normal (0.6-1.7 mm in thickness), 31 (12%) papyraceous (<0.5 mm), 8 (3%) thick, and 34 (13%) pneumatized. SSCD was observed in 27 (11%) cases. Statistically significant differences between the CL/P and control groups were evident in terms of SSCC morphology (p < .001). CONCLUSIONS: SSCD should be considered if a CL/P patient exhibits a vestibular system deficiency. Oral and maxillofacial radiologists should pay attention to SSCD when interpreting CBCT images. Future studies should use high-level spatial resolution CBCT to focus on cleft site and SSCC morphology in larger patient populations.
