Management of oro-antral fistula: Two case reports and review.

Oro-antral Communication is an unnatural communication between the oral cavity and maxillary sinus and when it fails to close spontaneously, it remains patent and is epithelialized so that oro-antral fistula develops. It is a common occurrence following removal of maxillary premolars and molars because of anatomic proximity of root apices of these teeth and maxillary antrum. Signs and symptoms of oro-antral fistula varies from free escape of fluids, pain, pus leakage, voice alteration, to pan-sinusitis. Several surgical options exist for its management, in particular the buccal fat pad technique, which has proved to be an effective and a reliable technique. We report in this article two-succefull cases of oro-antral fistula managed with buccal fat pad.

A capillary angioma of the lips: an extremely rare situation in the oral cavity / Angioma capilar de los labios: una situación extremadamente rara en la cavidad oral

Hemangiomas are tumors identified by rapid endothelial cell proliferation in early infancy, followed mostly by involution over the time. However, 10-12 % of true hemangiomas don't involute and require surgical treatment. Hemangiomas are classified on the basis of their histological appearance as capillary, mixed and cavernous. We report a case of capillary angioma in a 13-year old boy who presented with a budding into the lower lip. The lesion was excised and histopathological report confirmed the diagnosis.

Los hemangiomas son tumores identificados por la rápida proliferación de células endoteliales en la primera infancia, seguidos principalmente por involución a lo largo del tiempo. Sin embargo, entre el 10 y el 12 % de los hemangiomas no intervienen y no requieren tratamiento quirúrgico. Los hemangiomas se clasifican en función de su aspecto histológico como capilares, mixtos y cavernosos. Reportamos un caso de angioma capilar en un niño de 13 años que presentó un brote en el labio inferior. La lesión fue extirpada y el informe histopatológico confirmó el diagnóstico.

Management of oroantral communication using buccal advanced flap.

Oroantral communication (OAC) or fistula (OAF) is an open pathological communication between the oral cavity and maxillary sinus which mostly occurs as a result of extraction of upper molars and premolars, iatrogenic complications or from dental infections, osteomyelitis, radiation therapy or trauma. Several alternative techniques modalities have been described throughout the years for the management of OAC and OAF which show both advantages and limitations. The most employed surgical flaps are of three types: advanced buccal flap, palatal flap and buccal fat pad flap. The authors present two clinical cases: oroantral communication and oroantral fistula, both were treated by using buccal advancement flap.

Non syndromic supernumerary teeth: management of two clinical cases.

Supernumerary teeth are extra teeth or tooth-like structures. Single, double, or multiple teeth that occur in one or both jaws may be erupted or unerupted and unilateral or bilateral. Supernumeraries are less common in primary dentition than in permanent dentition. The etiology of ST is still unknown. A number of theories have been postulated to try to explain their presence, including atavism (evolutionary throwback), tooth germ dichotomy, genetic and environmental factors, and hyperactivity of the dental lamina. However, all theories are hypothetical due to the inability to obtain sufficient embryologic material on their origin. The aim of this paper is two present two case reports of non syndromic supernumerary teeth in female patients and their management.

Esthetic Improvement of a Nasolabial Cutaneous Sinus Tract.

A cutaneous sinus tract of dental origin is relatively uncommon and may easily be misdiagnosed, owing to its uncommon occurrence and absence of dental symptoms. Such a lesion continues to be a diagnostic dilemma. The case described here presented a nasolabial cutaneous sinus tract of dental origin that was treated by a surgical approach with an excellent esthetic improvement.

Evaluation of the Knowledge and Attitudes of Dental Students toward Occupational Blood Exposure Accidents at the End of the Dental Training Program.

AIMS AND OBJECTIVES: This study was conducted to assess knowledge, attitudes, and behavior regarding occupational blood exposure accidents (OBEA) among dental students at the end of the whole dental education program. MATERIALS AND METHODS: The survey was performed using a student self-administered questionnaire during July 2015 in the dental teaching hospital in Rabat. It was conducted on 117 dental students registered in the 5th year. The results were analyzed by SPSS Software, Version 13.0. Univariate analysis was performed by descriptive statistics, and bivariate analysis was used to identify correlations between different variables. RESULTS: Eighty-three students answered the questionnaire (participation rate: 70%). Most participants had incomplete knowledge about the management and the risks of OBEA. Thirty-five participants (42%) experienced at least one occupational exposure to patients' blood. Needle recapping has been the main cause of such injuries (41%). Most accidents occurred, respectively, in the oral surgery (51%) and the restorative dentistry (17%) departments. According to many participants, they had received insufficient education concerning this topic. CONCLUSIONS: More effective education on prevention and management of OBEA is highly recommended to reduce the prevalence of such injuries. Dental schools should set up a local management unit for following and supporting the exposed students.

Central odontogenic fibroma of the maxilla.

Central odontogenic fibroma (COF) is an uncommon tumor that accounts for 0.1% of all odontogenic tumors; it has been defined as a benign neoplasm of the jaw. Clinically, the lesion grows slowly and leads to cortical expansion. Radiologically, the most common finding is multilocular radiolucency. The lesions are associated with the crown of an unerupted molar, premolar, or incisor tooth and in some cases, with root resorption or displacement. Histologically, the lesion is characterized by mature collagen fibers and numerous fibroblasts. COF responds well to surgical enucleation with no tendency for malignancy or recurrence. We report a case of a 15-year-old female patient presented with painless swelling of the left side of the maxilla since her childhood. Radiographs revealed an expanding ill-defined radiolucency with a displacement of the adjacent tooth. The impacted tooth was pushed posteriorly. The lesion was removed surgically. There were no postoperative complications.

Florid osseous dysplasia: report of two cases and a review of the literature / Displasia ósea florida: reporte de dos casos y revisión de la literatura

Florid osseous dysplasia (FOD) is a benign condition of the jaws in which the normal architecture of bone is replaced by a fibrous tissue containing a variable amount of bone and cementum-like tissue. This lesion is most commonly seen in middle aged black women. FOD appears as dense, lobulated masses, often symmetrically located in the mandible, rarely in the maxilla. The lesion is usually asymptomatic and benign. However, a secondary infection may occur and its treatment can be difficult and complicated. This paper reports the case of two patients. The first one is a white woman aged 65 and the second one is a black woman aged 70, both diagnosed with FOD, revealed by secondary infections. The diagnosis was based on clinical and radiographic findings, as biopsy is contraindicated. Radiological and clinical features of FOD and its management will be also discussed on the basis of recent literature.

La displasia ósea florida (DOF) es una patología benigna del maxilar y mandíbula en la que se sustituye la arquitectura normal del hueso por un tejido fibroso que contiene una cantidad variable de tejido óseo y cementoide. Esta lesión es más frecuente en mujeres negras de edad media. La DOF aparece como una masa densa, lobulada, a menudo situada simétricamente en la mandíbula, rara vez en el maxilar. La lesión suele ser asintomática y benigna. Sin embargo, una infección secundaria puede ocurrir y su tratamiento puede ser difícil y complicarse. Este artículo reporta el caso de dos pacientes. La primera es una mujer blanca de 65 años y la segunda es una mujer negra de 70 años, ambas diagnosticadas con DOF, revelada por infecciones secundarias. El diagnóstico se basó en los hallazgos clínicos y radiológicos, ya que la biopsia está contraindicada. Las características clínicas y radiológicas de la DOF y su manejo son discutidos en base a la literatura reciente.
