A case of a hippopotamus bite on the shoulder of a fisherman has been reported. In addition to the osteoarticular aspect representing a therapeutic problem, the infectious aspect was marked by sepsis, with a death in less than 48 hours. Based on this observation, a protocol for the initial management of large animal bites was submitted.展开更多

The etiology of apical root resorption is multifactorial but largely depends upon the type of orthodontic tooth movement and treatment duration. Study Objective: The primary aim of this study is to examine the association of external apical root resorption and vertical correction in anterior open bite malocclusions using panoramic radiographs for evaluation. Materials and Methods: Pre-treatment and post-treatment panoramic radiographs of 16 patients with anterior open bite malocclusions were scored to assess root resorption of anterior teeth (U/L 3-3). Initial and final root length and total tooth length for U/L 3-3 were measured on panoramic radiographs in Dolphin imaging. Results: Of the 24 pairs of measurements, 7 had a significant p-value (p Conclusions: A statistically significant amount of root resorption was observed, from pre-treatment to post-treatment radiographs. All mandibular anterior teeth except the mandibular right lateral incisors showed evidence of root resorption.展开更多

It can lead to a poor outcome in both the mother and the fetus. We describe our approach to envenomation in pregnancy based on the currently available evidence. Case: We reported two case of snakebite in the third trimester of pregnancy having caused placental abruption with expelling a fresh still born baby and a live baby. In both cases, consumption coagulopathy occurred. managed by polyvalent anti-snake and blood transfusion. Their investigations became normal and they were discharged of hospitalization. Conclusion: Snakebite envenomation in pregnant is a maternal and fetal emergency. Treatment must be quick and well adapted.展开更多

文摘BACKGROUND Temporomandibular joint(TMJ)disorders are closely related to high-angle and skeletal Class II malocclusion.Sometimes pathological changes in the mandibular condyle can cause open bite to occur after growth is complete.CASE SUMMARY This article is about the treatment of an adult male patient with a severe hyperdivergent skeletal Class II base,an unusual and gradually occurring open bite and an abnormal mandibular condyle anterior displacement.Because the patient refused surgery,four second molars with cavities and root canal therapy were extracted,and four mini-screws were used for intrusion of the posterior teeth.The treatment duration was 22 mo,and after the treatment,the open bite was corrected and the displaced mandibular condyles were seated back to the articular fossa as shown by cone-beam computed tomography(CBCT).Based on the patient’s open bite history,the result of clinical examinations and CBCT comparisons,we believe it is possible that the occlusion interference was eliminated after the four second molars were extracted and the posterior teeth were intruded,and the patient's condyle spontaneously returned to its physiologic position.Finally,a normal overbite was established,and stable occlusion was achieved.CONCLUSION This case report suggested that identifying the cause of open bite is essential,and the TMJ factors for hyperdivergent skeletal Class II cases should be particularly examined.For these cases,intruding posterior teeth may place the condyle in a more appropriate position and provide an environment suitable for TMJ recovery.
