Grievances in cases using antibiotics due to orodental problems and assessment of the need for antibiotics.

OBJECTIVE: To assess the complaints of patients who were prescribed antibiotics following orodental problems and the need for antibiotics prescribed for this purpose. SETTING: Examinations were carried out in the Department of Oral Diagnosis and Radiology, Ege University, Turkey. PARTICIPANTS: A total of 203 patients (129 females and 74 males) between 8-70 years of age (mean age 37.7 +/- 13.9). INTERVENTION: Examination and report. MAIN OUTCOME MEASURES: Frequency of unnecessary antibiotic use. RESULTS: Antibiotic therapy was not necessary for 151 (74.4 per cent) cases. Antibiotics were unnecessarily prescribed in 45 cases of acute irreversible pulpitis, 10 chronic apical abscess, 6 acute apical paradontitis, 7 gingivitis, 10 periodontitis, 4 epulis, 2 TMJ (temporomandibular junction) dysfunction, 2 sharp ridge of alveolar bone, 1 burning mouth syndrome and 1 recurrent aphthous stomatitis. In 108 (53.2 per cent) of the cases, the prescribed antibiotics were found to be penicillins, 102 of which were broad-spectrum. It was also determined that only 6 (7.7 per cent) of the 78 cases diagnosed as acute apical abscess were given drainage as local therapy. CONCLUSIONS: Principles for treating dental infections suggest that an antibiotic should only be used to supplement and not substitute for conventional surgical methods. Therefore, in cases with acute apical abscess, mechanical treatment (drainage) should be the first step. Inappropriate antibiotic use is quite widespread in dentistry. Dentists should avoid inappropriate use of antibiotics. To prevent inappropriate administration, necessary precautions need to be taken against dispensing antibiotics without prescription.

A comparison of a film-based and a direct digital dental radiographic system using a proximal caries model.

OBJECTIVES: To compare the diagnostic accuracy of a dental radiographic film (Ektaspeed Plus) with the Sens-A-Ray direct digital imaging system using a proximal caries model. To study the effects of a scattering medium and compare the interpretations of dentists with dental students. METHODS: We used 20 extracted premolar and molar teeth with 10 sound and 15 naturally carious surfaces, and prepared artificial cavities in the remaining 15 surfaces. Seven dentists and seven senior dental students reported the presence of lesions using a five point confidence scale. We analysed our data by Receiver Operating Characteristic (ROC) analysis and by obtaining sensitivities and specificities. RESULTS: ROC areas showed no significant differences in the diagnostic accuracy achieved by dentists and dental students or by the addition of 20 mm of water as a scattering medium. A paler set of exposures produced significantly poorer diagnostic accuracy, but a darker set gave insignificant differences. Highly significant differences were found between the ROC areas for film and Sens-A-Ray and natural caries and artificial cavities, but the magnitudes of the differences were small. Sensitivities and specificities showed greater differences between methods and identified inferior interpretation of sound surfaces by students. CONCLUSIONS: Film was superior to Sens-A-Ray in the interpretation of proximal caries. The effects of a scattering medium were insignificant or trivial. Students were less reliable than dentists in the interpretation of sound surfaces but performed equally well with respect to natural caries and artificial cavities.

Multiple dens invaginatus. A case report.

A case of dens invaginatus in all four quadrants is reported. Although it is seen mostly in maxillary permanent incisors, mandibular involvement is rare. In this article, in addition to the involvement of the maxillary lateral incisors, the involvement of the right and left mandibular premolars has been presented as well.
