Hemangioma is the clinical term for a benign vascular neoplasm due to proliferation of the endothelial lining of blood vessels. Their most frequent location is the body skin and oral mucosa. One of the treatment modalities for hemangiomas is intralesional injection of sclerosing agents which cause the damage of blood vessels followed by their obliteration. The objective of the study was to describe the facility of application and evaluate the efficiency of sclerotherapy with aethoxysklerol 1%. Method. The case presented with intraoral submucosal hemangioma of the cheek was treated by intralesional injection of aethoxysklerol 3% diluted in water for injections at a 4 : 1 ratio (0.75%) at the first appointment and 3 : 1 (1%) at the second appointment. The effect of sclerotherapy was evaluated on the following visits in time intervals of two weeks. Results. The hemangioma disappeared without complications after the second injection of aethoxysklerol 1%. The successful results of the study were comparable to the data of literature with variations according to the used sclerosant agent, its concentration, the number of injections, and the intervals between each session. Conclusion. Since sclerotherapy is a very effective, inexpensive, and easy-to-apply treatment, it should be the treatment of choice, especially for intraoral superficial hemangiomas.

Cystic lesions of the jaws such as keratocysts (scientific community still continues to use the term 'odontogenic keratocyst' more favourably than 'keratocystic odontogenic tumour' although both terms remain acceptable synonyms), follicular cysts, radicular cysts, and residual cysts may reach large proportions, causing considerable bone destruction. Enucleation of cystic lesions in the jaw produces bone defects, which may recover spontaneously or with assisted healing with the use of autogenous bone graft or other bone substitute materials. This clinical study presents a spontaneous bone regeneration after residual cyst enucleation in the distal part of the maxilla. The progress of recovery is followed by clinical and radiographic examination and subjective data obtained from the patient. Bone regeneration and cystic cavity reduction was observed in the panoramic image after six months and after one year. The physiological process of coagulation provides the basic process for the spontaneous bone formation even if an osseous defect is considerably large, provided that the defect is surrounded by adequate bony walls.

The presence of an embedded foreign body in the oral and maxillofacial region is not unusual, but the impaction of a foreign body with vegetative nature is rare. Prompt diagnosis and surgical removal of these foreign bodies will minimize their associated complications. This case report presents a patient with recurrent submandibular abscess and persistent facial cutaneous sinus tract caused by a retained blade of grass inside the facial soft tissue. The fact that the plain radiograph misdiagnosed the presence of a foreign body meant that the pathology persisted for about three months, and the patient underwent hospitalization, surgical procedures, and antibiotic regimens; however all of these failed until the foreign body was detected and removed. Conclusion. To avoid misdiagnosis of foreign body presence in the orofacial region, notably suspected foreign bodies with low radiopacity, the clinician must perform careful clinical examination and use the ultrasonography. Also, in the uncertain cases where the pathology persists, despite having undertaken surgical procedures and antibiotic regimens, the clinician should pay more attention to the patient's history which may suggest the presence of the foreign body.

Introduction: Hemisection refers to the surgical separation of multirooted teeth when the decay or resorption is restricted to one root, followed by removal of the affected root with preservation of the healthy root with its crown portion and its usage as abutment for subsequent prosthetic restoration. Aim: The aim of this case report was to raise awareness among dentists that preservation of tooth structure in the form of hemisection may be considered an alternative treatment modality in cases of multirooted teeth with extensive caries restricted to one of the roots. Case description: This describes the hemisection procedure of right mandibular second molar performed in a 35-year-old female referred for extraction. Intraoral examination and intraoral periapical (IOPA) radiography revealed extensive decay of tooth 47, restricted to the distal root, with satisfactory condition of the mesial root and its crown portion to be preserved by hemisection and used as abutment for a fixed prosthetic restoration. 6 weeks after the successful hemisection, a three-unit metal-porcelain fixed denture was performed, using the retained mesial root of mandibular second molar (47) and the mandibular second premolar (45) as abutments and replacing the missing mandibular first molar (46). Conclusion: Preservation of tooth structure by performing hemisection in carious multirooted teeth in cases when caries is restricted to one of the roots should be considered a valuable alternative treatment instead of extraction; therefore, it should be discussed with patients as one of the treatment options whenever suitable and possible to perform. Clinical significance: The rationale of hemisection in our case is that it enabled the preservation of tooth structure by supplying an abutment for construction of a three-unit fixed partial denture, thus providing the patient the opportunity to maintain occlusal function with reduced financial cost over dental implants.
