RESUMO
Blows to the facial region can cause root fractures especially in anterior teeth. Fractures below the alveolar crest have a very high potential for healing and treatment consists of reduction and rigid splinting immediately after trauma. The aim of the treatment is to obtain reunion of the fragments. Although the fracture can heal spontaneously, the prognosis will not be as good as the correctly treated ones. The purpose of this paper is to report a case of spontaneously healed root fracture.

A few cases of bifid, but no case of trifid mandibular condyle, have been reported in the literature. This article presents the first reported case of trifid mandibular condyle in a living subject with a history of previous trauma to the temporomandibular joint (TMJ). Additionally, the patient's other condyle was bifid. The patient had no complaint related to the functions of TMJ except for minimal weakness following chewing. The etiology and the prognosis of bifid and trifid condyle are discussed briefly. We considered computed tomography essential to rule out early stages of TMJ pathology in similar cases that resemble trifid mandibular condyle on conventional radiographs.

OBJECTIVE: To compare the degree of keratinization of buccal mucosa between nonsmoking menstruating and postmenopausal women without oral complaints whose iron status was established. STUDY DESIGN: Samples collected from 26 nonsmoking, regularly menstruating women (mean age, 26 years) and 18 nonsmoking, postmenopausal women without oral complaints (mean age, 57 years) were stained according to the method of Papanicolaou. Keratinization was evaluated by the karyopyknotic index (KI). Iron status was assessed with blood ferritin levels. RESULTS: Mean ferritin values of menstruating and postmenopausal women were statistically significantly different (mean ferritin value = 28.97 micrograms/L and 103.69 micrograms/L, respectively). The difference in the degree of keratinization of buccal mucosa between menstruating women (mean KI = 16.03%) and postmenopausal women (mean KI = 13.16) was statistically nonsignificant. CONCLUSION: Our results indicate that the degree of keratinization of buccal mucosa does not show any alteration after menopause.
