A 2-plane micro-computed tomographic alveolar bone measurement approach in mice

Purpose: This study introduces a standardized 2-plane approach using 8 landmarks to assess alveolar bone levels in mice using micro-computed tomography. Materials and Methods: Bone level differences were described as distance from the cemento-enamel junction (CEJ) to alveolar bone crest (ABC) and as percentages of vertical bone height and vertical bone loss, comparing mice infected with Porphyromonas gingivalis (Pg) to controls. Eight measurements were obtained per tooth: 2 in the sagittal plane (mesial and distal) and 6 in the coronal plane (mesiobuccal, middle-buccal, distobuccal, mesiolingual, middle-lingual, and distolingual). Results: Significant differences in the CEJ-to-ABC distance between Pg-infected mice and controls were found in the coronal plane (middle-lingual, mesiobuccal, and distolingual for the first molar; and mesiobuccal, middle- buccal, and distolingual for the second molar). In the sagittal plane, the distal measurement of the second molar was different. The middle-buccal, mesiobuccal, and distolingual sites of the first and second molars showed vertical bone loss relative to controls; the second molar middle-lingual site was also different. In the sagittal plane, the mesial sites of the first and second molars and the distal site of the second molar showed loss. Significantly different vertical bone height percentages were found for the mesial and distal sites of the second molar (sagittal plane) and the middle-lingual and distolingual sites of the first molar (coronal plane). Conclusion: A reliable, standardized technique for linear periodontal assessments in mice is described. Alveolar bone loss occurred mostly on the lingual surface of the coronal plane, which is often omitted in studies.

Osteoma is a benign osteogenic tumor composed of cancellous or compact bone, classified as peripheral, central, or extraskeletal. Peripheral osteomas are uncommon. Excluding the maxillary sinuses, the maxilla is a rare site for osteomas. The purpose of this report was to describe clinicopathological and radiological features of two peripheral osteomas occurring in the jaws, one located in the mandible and another in the edentulous maxillary alveolar ridge. The tumors were asymptomatic and were fully excised without any complications or recurrence. The lesions were submitted to histopathological analysis and diagnosed as peripheral osteoma, compact type.

Medicinal plants with antimicrobial action havebeen investigated for uses against biofilms, among which,Cymbopogon nardus, citronella, stands out as a promisingspecies. The present study aims to evaluate the antimicrobialand antibiofilm action of the essential oil of C. nardus (EOCN) and geraniol on Gram-negative and positivebacteria from the determination of minimum inhibitoryconcentration (MIC) and minimum bactericidal concentrationand inhibition of biofilms. In the results, the EOCNproduced a 41 mm halo on S. aureus, which was susceptiblewith MIC values of 0.5 and 0.25 mg/mL for theEOCN and geraniol respectively, both with bactericidaleffect. The antibiofilm action was confirmed, the EOCNand geraniol reduced the biofilm biomass of S. aureus up to100% between 0.5 and 4 mg/mL concentrations. Thereduction of cell viability was 0.25 and 1 mg/mL, ofEOCN and geraniol, respectively. EOCN and geraniol wereshown to be promising antibiotic against S. aureus.
