[Action of Calendula officinalis essence on bone preservation after the extraction].

Background: Calendula officinalis is a phytodrug used as analgesic, antiseptic and wound-healing agent due to its collagenogenic effect, which is why it is a convenient and affordable treatment that promotes alveolar bone preservation after tooth extraction in vivo. The aim of this study was to use Calendula officinalis during and after tooth extraction to determine its ability to preserve bone after this procedure.

Methods: We established two groups matched by age, gender and position of the third molar.

[Complex of amniotic deformities, adhesions, mutilations: Endless debate].

Amniotic deformities, adhesions, mutilations (ADAM) complex is a broad heterogeneous spectrum of congenital anomalies. ADAM complex is characterized by constriction rings, amputation of fingers or limbs and the presence of the amniotic band. However, it may also involve craniofacial disruptions, body wall defects and internal organ abnormalities.

[A case reported of an ameloblastic fibroma in which involved three right molars in a teenager].

Ameloblastic fibroma is a benign tumor of mixed odontogenic origin, which occurs in ages from 12 to 15 years, frequently in the molar area. Generally it is asymptomatic, however the biggest lesions can be associated to pain and swelling. Using X-ray they appear well defined, transparent, with a sclerotic radio-opaque border; occasionally they can simulate a dentigerous cyst.

[The third dimension tomography versus cranial X-ray cephalometry to predict maxilla advance by distraction in hypoplastic maxilla].

Background: the osteogenic distraction is the treatment for the correction of the hypoplastic maxilla secondary to the repair of a cleft lip-palate. Its planning is based on articulated models. Our objective was to describe the accuracy of three-dimensional Cephalometry (CT3D) for projecting jaw displacement.
