Long-term follow-up of a large multilocular odontogenic keratocyst. Analysis of recurrences and the applied treatments.

Recurrence is a well-known feature of odontogenic keratocyst (OKC). Compared with other odontogenic cysts, OKC is characterized by an infiltrating growth, aggressive biological behavior, and a greater tendency towards recurrence once removed, particularly when simple enucleation has been carried out. The recurrence rate is largely dependent upon the type of treatment applied; consequently, the planning of management must take into account the possible reasons why the cyst may recur.

Odontogenic maxillary sinusitis and fungus ball development secondary to a dental root retained for more than 25 years. A case report.

The displacement of a dental root fragment into the maxillary sinus is a serious complication of tooth extraction that can give rise to maxillary sinusitis. The condition can become chronic if the intrasinusal foreign body is not promptly removed, and Aspergillus fumigatus superinfection may ultimately result, forming a fungus ball. The present study describes the case of a 50-year-old man with fungal rhinosinusitis caused by the accidental displacement of a dental root over 25 years ago.

Third molar surgical difficulty scales: systematic review and preoperative assessment form.

Background: The main objective of this systematic review was to collect the pre-existing scales for assessing the difficulty of third molar extraction. The secondary objective was to design a proposal for a preoperative evaluation protocol for the difficulty of third molar extraction.

Material And Methods: Two independent researchers conducted an electronic search in Pubmed (MEDLINE), Cochrane, and Scopus databases during March 2021.

Giant deep lobe parotid tumor removal via total parotidectomy without mandibulotomy. A simple and safe technique.

The transmandibular route is often combined with the transparotid-transcervical approach when extensive surgical field exposure is required, as in the case of deep parotid lobe tumors measuring over 4 cm in size. This procedure implies great morbidity and prolongs surgery time. Furthermore, in cases where additional lip division is performed, the aesthetic outcomes may be poorer.

Therapeutic management of the odontogenic keratocyst. An energetic approach with a conservative perspective and review of the current therapeutic options.

Background: Odontogenic keratocysts (OKC) are cystic lesions appearing in the jaws, usually asymptomatic with a progressive growth into the bone. Many of them are diagnosed by a routine radiological examination.

Material And Methods: This study reports a 12-year-old girl that presented an asymptomatic large radiolucent unilocular lesion associated to the crown of 3.

Bifid mandibular condyles: A systematic review.

Background: Bifid mandibular condyle (BMC) constitutes an extremely rare disorder characterized by a duplication of the head of the mandibular condyle. Its prevalence ranges from 0.31% to 1.

Dentigerous cyst with parietal and intracystic calcifications: A case report and literature review.

Background: Dentigerous cyst appears surrounding the crown of an included tooth. On the radiographic exam, a radiolucent rounded well-defined lesion can be observed.

Material And Methods: This study reports a clinical case of a 34-years old man with a pericoronal radiolucent lesion associated to an impacted lower third molar with the presence of radiopaque material inside.

Malignant changes developing from odontogenic cysts: A systematic review.

The aim of this study was to systematically review scientific literature in orderto describe the characteristics and prognosis of malignant entities developing from odontogenic cysts. A search in Pubmed (MEDLINE) and Cochrane databases was conducted. The inclusion criteria were articles published in English related to the malignisation of odontogenic cysts in humans.
