The prevalence of carotid artery calcification on the panoramic radiographs of patients with renal disease.

OBJECTIVES: To determine the prevalence of carotid calcification on dental panoramic radiographs in end-stage renal disease (ESRD) patients on haemodialysis and renal transplant recipients. METHODS: Panoramic radiographs of 69 adult patients with renal disease (34 with haemodialysis and 35 with renal transplantations) (age range 17-74 years; mean age 39.45 years) and 50 controls (age-match, free of systemic disease) were examined on panoramic radiographs for any unusual radiopacity adjacent to or just below the intervertebral space between C3 and C4. Patients with such calcifications were referred to ultrasound examination. Using Chi-squared tests, calcification prevalence rates were statistically compared. RESULTS: The statistical difference between renal disease patients and control group was significant (chi2 = 17.91, P < 0.001). On comparison of haemodialysis patients and renal transplant recipients with controls, statistical difference (P=0.007) was found to be significant. CONCLUSION: Carotid artery calcification was higher in haemodialysis patients and renal transplant recipients. These patients with such calcifications should be referred for further evaluation and treatment of carotid arteries, coronary arteries and vascular risk factors.

Bilateral bifid mandibular condyle.

Bilateral bifid mandibular condyles are rare and may appear as a congenital or developmental anomaly. A case of bilateral bifid mandibular condyles is reported. The patient had no history of trauma and no link was apparent with respect to the patient's medical history. In this case, the condition was an incidental panoramic radiographic finding. Magnetic resonance imaging findings revealed bilateral anterior disc displacement without reduction. The radiographic appearance of this anomaly and the literature on bilateral bifid condyles are reviewed.

The prevalence of tongue lesions in 5150 Turkish dental outpatients.

OBJECTIVE: The aim of this study was to assess the prevalence of nine tongue conditions and relate to data obtained about oral hygiene or habits in Turkish dental outpatients. SUBJECTS: A total of 5150 subjects (2837 women, 2313 men) were included in this study. RESULTS: Of the 5150 subjects, 2690 subjects were detected as having tongue lesions with a prevalence of 44.2 and 62.0% for women and men, respectively. The difference was found to be statistically significant (P < 0.0001). There was a strong correlation between tongue lesions and increasing age. There was also a strong association between tongue lesions and smoking, black tea drinking, and fair or poor oral hygiene. Hairy and coated tongue was significantly higher in males. Contrary to this, papillary atrophy was more prominent in women. CONCLUSION: A strong correlation was found between tongue lesions and age, sex, oral hygiene and habits in Turkish dental outpatients. An efficient oral health program such as the elimination of risk habits and attention to cultural practices may improve tongue hygiene.

The relationship between gastric-oral Helicobacter pylori and oral hygiene in patients with vitamin B12-deficiency anemia.

OBJECTIVE: The aim of this study was to determine whether a relationship exists between gastric and oral Helicobacter pylori and oral hygiene in patients with vitamin B12 deficiency. STUDY DESIGN: One hundred eight patients with vitamin B12 deficiency who were H pylori -positive in their gastric mucosa were enrolled in the study. These patients were divided into 3 groups determined by Oral Hygiene Index (OHI) scores of good, fair, or poor. H pylori was detected in the dental plaque with camphylobacter-like organism test gels. All patients were treated with a combination regimen to eradicate H pylori. RESULTS: H pylori positivity in dental plaque was correlated with OHI scores; the positivity was 28.5%, 90.2%, or 100% in patients with good, fair, or poor OHI scores, respectively. The eradication of H pylori was associated with recovery from anemia and increased serum vitamin B12 level (P <.0001 and P <.0001). The patients with poor OHI scores had the most frequent gastric recurrence of H pylori (58.3%) compared with those with fair OHI scores (41.2%) and good OHI scores (4.8%). CONCLUSIONS: H pylori seems to be an etiologic factor in vitamin B12 deficiency, since anemia was cured and the level of vitamin B12 in the serum increased as a result of its eradication. However, eradication of H pylori from gastric mucosa alone is not enough to prevent gastric recurrence of the bacteria. Proper oral hygiene must be established to eliminate H pylori in dental plaque. Therefore, we suggest that control of H pylori in dental plaque is necessary to control recurrence of H pylori.
