[The change of calcitonin gene-related peptide positive fibers in inflammatory pulps].
Deep cavities were prepared on rats' molars, and fresh carious dentin was enclosed in to establish animal pulpitis model. Immunohistochemical method was used to observe the distribution of calcitonin gene-related peptide (CGRP) positive nerve fibers in rats' normal dental pulps and inflammatory pulps at 4d, 8d, 14d respectively. CGRP positive fibers were found throughout the normal pulps, a large number of fibers penetrated into dentinal tubules. ⋯ In 8d group, a necrotic zone could be found in the coronal pulps, lots of fibers accumulated around the necrotic zone. In the radical pulps, CGRP positive fibers formed multiple arborizations. 14d postinflammation, all the pulps were necrotic, and the periapexs were richly innervated by CGRP positive fibers. The results suggesting that CGRP may play a role in the inflammation and repair of dental pulp.

[Surgical correction of dentofacial deformities following temporomandibular joint ankylosis].
The paper presents 22 patients (9 male, 13 female; 13 unilateral, 9 bilateral) with temporomandibular ankylosis and dentofacial deformities treated by arthroplasty and orthognathic operations. The results were satisfactory. The key point is to ensure the function of mouth opening and correction of dentofacial deformities caused by ankylosis. The indications for one-stage or two-stage surgical correction are discussed.

[The relationship between family background and craniofacial morphology in class III malocclusions].
Fifty five children with deciduous dentition and 36 adults were selected from 160 Class III patients, 40 children with normal occlusion used as cephalometric control group. T test was operated between the children with normal occlusion, Class III malocclusion with positive family background and with negative family background separately, and distinct analysis was carried out between the two Class III groups. ⋯ Results show that craniofacial deformities of deciduous Class III malocclusion with positive family background are not more serious than those with negative one, and the rate of developing a skeletal class III malocclusion for patients with positive family background is not higher than those with negative one. It was implied that the value of family information collected by inquiring and cursorily examining the parents is limited for differential diagnosis between skeletal and functional class III malocclusion and it may mislead the prediction of treatment result in orthodontic clinic.
