Resumo: | Abstract Objective: assess the distribution and quantity of osteoclasts on periodontal ligament of rabbit’s molars in physiological conditions. Methodology: one hundred and seventy-six histological sections were analyzed, obtained through bone blocks removed from the first molar regions on both sides of the mandible of 44 rabbits. Sections were stained with TRAP technique. Results: osteoclasts were found in 53,98% of the slides and were absent in 46,02%. These cells were usually located on the cervical and median third. Nonparametric Friedman Exact test evidenced a statistically significant difference between the thirds, and Dunn’s a Posteriori test indicated such difference between apical and cervical thirds and apical and median thirds (p<0,05). Conclusion: physiological re-modeling of the alveolar bone occurs when stress generated is sufficient to induce monocytes differentiation in osteoclasts. These cells are more concentrated on the cervical and median thirds due to the direction of the dental movement. Keywords: Osteoclasts. Periodontal ligament. Bone Remodeling |

Bone RemodelingObjetivo: avaliar a distribuição e a quantidade dos osteoclastos no ligamento periodontal de molares de coelhos em condições fisiológicas. Metodologia: foram analisadas 176 secções histológicas obtidas através de blocos de osso removidos da região de primeiro molar de ambos os lados da mandíbula de 44 coelhos. As secções foram coradas pela técnica de TRAP (Fosfatase ácida tartarato-resistente). Resultados: na análise dos resultados, em 53,98% das lâminas não havia osteoclastos, enquanto que em 46,02% a presença desta célula foi detectada. Quando presentes localizaram-se mais nos terços cervical e médio. O teste não-paramétrico Exato de Friedman evidenciou diferença estatisticamente significante entre os terços e o teste a Posteriori de Dunn indicou essa diferença entre os terços apical e cervical, e apical e médio (p<0,05). Conclusão: conclui-se que o remodelamento fisiológico do osso alveolar acontece quando o stress gerado sobre ele é suficiente para induzir a diferenciação de monócitos em osteoclastos. Estas células concentram-se mais nos terços cervical e médio devido à direção do movimento dentário.Submitted by ROBERTO PAULO CORREIA DE ARAÚJO (ppgorgsistem@ufba.br) on 2017-06-19T16:40:57Z No. of bitstreams: 1 2_v.12_3.pdf: 745144 bytes, checksum: d1dab946d56ac62ad1140b0df327977d (MD5)Made available in DSpace on 2017-06-19T16:40:57Z (GMT).
