Application of a new composite mineralized collagen membrane in alveolar ridge preservation in dogs / 实用口腔医学杂志

Objective:To study the feasibility of a new composite mineralized collagen membrane in alveolar ridge preservation.Methods:The third mandibular premolars on both sides were extracted from 12 dogs,the 24 alveolar sockets were randomly assigned into A,B and C groups(n =8).The distal alveolar sockets of group A was immediately implanted with the new composite mineralized collagen membrane and bone graft material,those of group B with bone graft material,group C was the blank control.The healing of sockets was evaluated by gross observation,morphological measurements,X-ray microscope and photographs of spiral CT.Results:The horizontal width of the alveolar process of group A was bigger than that of group B (P ＜ 0.05),that of group B was bigger than that of group C (P ＜ 0.05).The region of extraction interest in spiral CT value was higher in group A than that in group B and C (P ＜ 0.05).The extraction sockets were generated new bone and the degree of reconstruction measurements was higher in group A than that in group B and C (P ＜ 0.05).Conclusion:The new composite mineralized collagen membrane can induce the regeneration of new bone,and preserve the alveolar.

A Importância da avaliação do coagulograma em pacientes submetidos a procedimentos de extração dentária / The importance of the evaluation of coagulogram in patients submitted to procedures for denatl extraction

Objetivo: descrever a importância da avaliação do coagulograma em pacientes submetidos aprocedimentos de extração dentária. Método: foi realizada uma revisão de literatura em artigosnacionais e internacionais, monografias e revistas sobre o assunto. Considerações finais:pacientes com alterações na hemostasia podem ser submetidos a procedimentos odontológicosdesde que o cirurgião-dentista realize, adequadamente, uma boa anamnese associada àinterpretação correta do coagulograma

Objective: to describe the importance of evaluate the coagulogram in patients submitted todental extraction procedures. Method: it was performed a literature review in articles fromnational and international journals and monographs about the subject. Final Thoughts: patientswith hemostasis disturbs can be submitted to dental procedures if the surgeon-dentist perform anadequate clinical history associated with a correct interpretation of the coagulogram
