[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. We used with patients on the experimental group Calendula officinalis diluted 10% as an irrigant during surgical extraction of third molars. We performed the conventional way with the control group irrigating with saline solution. Subsequently, both groups continued to make mouthwash for a week with the irrigating agent. Every week for a month, each patient underwent periapical radiography, out of which we took measurements of alveolar ridges and depth of alveolar bone, which were compared.

CONCLUSIONS

There is statistically significant evidence to state that Calendula officinalis favorably affects bone preservation after extraction.

[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 treatment is generally conservative. This report describes an ameloblastic fibroma in a 14-year-old male, which involved the three right molars and both the ascending ramous and the coronoid process, which was treated conservatively with the extraction of the affected teeth, tumor extirpation and osseous curettage.

[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.

METHODS

three patients with hypoplastic maxilla. Interventions estimation of the advance required of lateral maxilla through Cephalometry of skull (CLC), CT3D and an articulated model (gold standard). Two months after distraction finalized the advance predicted was compared.

RESULTS

the error of the advance projection in each patient was smaller with the CT3D versus CLC (+1, +1 and +1 mm versus -10, -14 and -9mm). Corrections post-distraction were of +25 %, +26 % and +38.4 % on the programmed one. CT3D predicted better the correction (+19 %, +10.8 %, +33.4 % versus CLC: -50 %; -60.8 % and -34.6 %). Chewing alterations were not seen in any patient.

CONCLUSIONS

the planning of the necessary advance for distraction in patients with hypoplastic maxilla by CT3D can shorten the time of studies and should be consider as next to the projection of articulated model.
