A capacidade reacional do osso e os nomes das doenças ósseas inflamatórias / The bone reactional capability and thenames of inflammatory bone diseases

As reações ósseas frente às demandas funcionais e agressões são diferentes de acordo com a morfologia do local, intensidade e duração da irritação e do estado sistêmico do paciente. Nesse trabalho, inicialmente procurou-se correlacionar esses três importantes fatores para compreender o resultado final na estrutura óssea, especialmente do ponto de vista imaginológico. Em seguida, são apresentados os conceitos dos nomes universalmente aceitos para identificar as doenças ósseas inflamatórias, de forma a facilitar a comunicação científica e clínica entre os profissionais.

The bone reactions before functional demands and aggressions are different according to the local morphology,intensity and duration of the irritation and systemic state of the patient. In this work, initially it was sought to correlate these three important factors to comprehend the final result on the bone structure, especially from the imaging point of view. Then, it was presented the concepts of universally accepted names to identify inflammatory bone diseases, in order to facilitate the scientific and clinical communication between professionals.

Correlation of periodontal status and bone mineral density in postmenopausal women: A digital radiographic and quantitative ultrasound study.

Background: Data suggest that postmenopausal women with osteoporosis are at an increased risk for periodontal attachment loss and tooth loss; however, the extent of relationship between these two diseases is still not clear. Aim: The aim of the study was to evaluate the correlation of periodontal status and bone mineral density (BMD) in postmenopausal women. Materials and Methods: The study population included 60 postmenopausal women aged 50-60 years (mean±SD: 55.5±3.4 years). Periodontal status was examined by plaque index, bleeding index, probing depth, and clinical attachment level (CAL). Digital panoramic radiograph was taken to measure the maxillary and mandibular alveolar bone density values. Skeletal (calcaneal) BMD was measured by quantitative ultrasound technique for T-score values. The recorded data for T-score, maxillary and mandibular alveolar bone densities, and periodontal status were subjected to statistical analysis for correlation and regression procedures. Results: The results showed that mandibular alveolar (r=0.907, P<0.001) and maxillary alveolar bone density (r=0.898, P<0.001) had significant positive correlation with calcaneal T-score. Probing depth (r=-0.316, P<0.05), bleeding index (r=-0.277, P<0.05), and plaque index (r=-0.285, P<0.05) showed weak but significant negative correlation with calcaneal T-score and alveolar bone density of both the jaws, whereas CAL showed weak correlation with T-score which could not reach to a statistically significance level (r=-0.221, P>0.05). Conclusion: Calcaneal BMD was related to alveolar bone loss and, to a lesser extent, to clinical attachment loss, implicating postmenopausal bone loss as a risk indicator for periodontal disease in postmenopausal women.
