Tongue-tie or ankyloglossia is a developmental anomaly of the tongue characterized by an abnormally short, thick lingual frenulum resulting in limited tongue movement. Ankyloglossia can affect feeding, speech and oral hygiene, as well as have mechanical and social effects. Diagnosis of tongue-tie is based on a clinical examination. Tongue mobility and appearance associated with the insertion, as well as the attachment and the shortness of the lingual frenulum should be evaluated. Ankyloglossia management should be considered at any age considering the risk-benefit evaluation and because of the highest vascularization and mobility of tongue; lingual frenectomy should be performed with less traumatic events to avoid postoperative complications. The aim of this article is to report 2 cases of ankyloglossia in young patients who were referred to the Department of Oral Surgery of the Faculty of Dentistry at the Mohamed V University of Rabat, Morocco. According to Kotlow's classification, both patients were diagnosed with Class II and treated with surgical frenectomy, followed by speech therapy for an immediate rehabilitation. A marked improvement in the movement of the tongue was observed at a follow-up visits in the treated cases.

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.

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.

Another aspect of diagnosis error concerns mucosal disease.We report a case of a 57-year-old male patient, with a complaint of a non-healing ulcer on the left posterior oral mucosa. The patient had consulted one month ago, a general dentist who considered the lesion as a dental abscess, without any radiographic examination, and prescribed antibiotics to him. The physical examination was difficult due to painful trismus which was <2½ cm. A single well-
