Cherubism is a rare, nonneoplastic, fibro-osseous disease. It is an autosomal-dominant disorder in which the normal bone is replaced by cellular fibrous tissue and immature bone. It is genetically inherited, although many nonfamilial cases have been reported. Cherubism is a bone disease clinically characterized by bilateral, painless enlargements of the jaws. The mandible is the most severely affected craniofacial component, in which uncontrolled growth of the malady deteriorates the aesthetic balance of the face. A malocclusive and abnormal dentition, worse in the mandible, can be seen. Histopathologically, numerous randomly distributed multinucleated giant cells and vascular spaces within a fibrous connective tissue stroma with or without eosinophilic collagen perivascular cuffing were apparent. The appearance of the affected children is normal at birth. Between the ages of 2 and 7 years, swellings within the mandibular body or tuberosities of maxilla appear. This article relates to a postpubertal nonfamilial cherubism case that was noticed with multiple radiolucencies in radiographic examination and its effects on teeth.

Masseter muscle hypertrophy is a rare condition of unknown cause which is important in the differential diagnosis of head and neck masses, located in the cheek. Several treatment options reported for masseter hypertrophy, which range from simple pharmacotherapy to more invasive surgical reduction. Botulinum toxin type A is a powerful neurotoxin which is produced by the anaerobic organism Clostridium botulinum and when injected into a muscle causes interference with the neurotransmitter mechanism producing selective paralysis and subsequent atrophy of the muscle. Injection of botulinum toxin type A into the masseter muscle is generally considered a less invasive modality and has been advocated for cosmetic sculpting of the lower face. Botulinum toxin type A injection is considered to be a beneficial treatment modality in masseter muscle hypertrophy patients. The aim of this article is to report two cases of masseteric muscle hypertrophy which were treated with botulinum toxin type A injection. Marked changes in facial feature were achieved 3 months after the procedure.

Objectives: The purpose of this study is to investigate the effects of monocryl (Polyglecaprone 25), silk and catgut suture materials on wound healing in diabetic rats and to evaluate NO (nitric oxide) dynamics., Study Design: Fourty-eight male Wistar-Albino rats weighing 220-270 g were used in this study. The rats were categorized into 2 groups, as control group (n=24) and streptozotocin (STZ) induced diabetic group (n=24). For each group, incision wounds were created on the inner cheek mucosa of the animals and wounds were closed primarily with three different types of sutures. These materials were sized 3-0 monocryl (polyglecaprone 25), silk and catgut sutures swaged on. Excisional biopsies were performed at 2nd, 7th, 14th and 21st day (2 rats per day) from the initial surgical procedure. Effects of these suture materials on wound healing and NOS (nitric oxide synthase) activities were compared immunohistochemically in the study. eNOS and iNOS (Endothelial and induced nitric oxide synthase) activities were classified as mild (+), moderate (++) and severe (+++)., Results: Mild eNOS activities were seen in both diabetic and control groups at 2nd day specimens. Activities of silk and catgut were similar both in diabetic and control groups at 14th day, this activity in monocryl was mild. 21st day specimens revealed that monocryl has mild eNOS activity than silk and catgut sutures. iNOS activities in diabetic group were greater than control groups and the degrees of the activity in monocryl, silk and catgut sutures were mild, severe and moderate at the 7th day. At the 14th day there was no iNOS activity in diabetic monocryl group., Conclusion: All of the materials have the potential capacity to be well tolerated however monocryl seemed to have more beneficial effects on wound healing in diabetic subjects.

Objective: The objective of the present study was to investigate the pain on injection of articaine with adrenaline, prilocaine with phenylpressin , and lidocaine with adrenaline., Study Design: The study sample was comprised of 497 consecutively seen patients received 497 maxillary buccal infiltration injections or inferior alveolar block injections of 4% articaine with 1:200.000 adrenaline, 3% prilocaine with 1.08 mcg phenylpressin, or 2% lidocaine with 1:100.000 adrenaline. Immediately after the injection, patients were asked to rate their injection pain on a six-point scale., Results: There were no significant differences among the anesthetic solutions for injection pain. Patients usually reported mild or no injection pain for all of anesthetic administrations., Conclusion: Under the conditions of this study that lidocaine with adrenaline, articaine with adrenaline and prilocaine with phenylpressin seemed to be similar for pain on injection and they could be quite painless.

Distraction osteogenesis is an efficient method to augment the mandibular alveolar process for dental implants. Complications of this procedure include fracture of the basal bone, breakage of distractor, wound dehiscenses, undesirable soft tissue changes, and defective movement of the transported segment. We report a case of breakage of the distractor after mandibular alveolar vertical distraction osteogenesis. Mandibular alveolar vertical distraction osteogenesis was applied to 53-year-old woman for prosthetic rehabilitation. Fracture of the distraction device occurred on the 13th day of the activation phase. Radiographic examination revealed the fracture of the distractor rod and lingually displaced alveolar segment. Lingually displaced segment was successfully advanced to the desired position, and fixed to the basal bone using dental implants before the maturation of the distracted bone. We consider that this technique is eligible for the management of these kind of complications.

Aim: The purpose of this report is to present two cases of totally impacted maxillary deciduous molars, considered a rarity in dental practice., Background: Primary tooth impaction is quite rare during the development of primary dentition. Various factors contribute to the impaction of a deciduous tooth, including anklyosis, congenitally missing permanent teeth, defects in the periodontal membrane, trauma, injury of the periodontal ligament, precocious eruption of the first permanent molar, defective eruptive force, or a combination of these factors., Reports: Case #1: An 18-year-old male presented with a complaint of spontaneous repetitious pain in the maxillary right premolar region. The maxillary right second premolar was clinically absent. Panoramic and periapical radiographs revealed an impacted second premolar close to the inferior wall of the maxillary sinus and an impacted deciduous molar deeply embedded in bone within the maxillary sinus. Case #2: A 14-year-old girl presented with a complaint of crowding of the maxillary teeth. The maxillary right second premolar and the maxillary permanent canines were clinically absent. A panoramic radiograph revealed an impacted maxillary right second premolar and an impacted deciduous molar embedded within bone close to the inferior wall of the maxillary sinus., Summary: The total impactation of deciduous teeth is a rare condition, and few cases have been reported in the literature. The condition generally affects the mandibular second deciduous molar and the maxillary first deciduous least often. In this paper, two cases of totally impacted maxillary deciduous molars are reported.

Aim: The purpose of this case report is to present a case of a non-syndrome male patient with multiple supplemental supernumerary teeth in three quadrants of his mouth., Background: Supernumerary teeth are described as the teeth formed in excess of the number found in a normal dentition. Prevalence of supernumerary teeth varies between 0.1% and 3.8% in the general Caucasian population. Multiple supernumerary teeth are not a common occurrence, although a single or a few supernumerary tooth/teeth in each case have been widely reported in the literature., Report: An 11-year-old male presented for a routine preventive dental visit. A routine panoramic radiograph showed the presence of multiple supernumerary teeth which were located in the maxillary right canine incisor region, the maxillary left premolar region, and the mandibular right premolar region. The family's medical history was non-contributory, and an extraoral examination did not reveal any abnormality., Summary: It is rare to find multiple supernumerary teeth in individuals with no other associated diseases or syndromes. This case report presents a case of a non-syndrome male patient with multiple supplemental supernumerary teeth in three quadrants of his mouth.

We compared the biomechanical behaviour of various rigid internal fixation techniques for treatment of fractures of the mandibular condylar process. Fifteen sheep hemimandibles were used to evaluate three bicortical plating techniques. A custom-made 3-point biomechanical test model was used for the samples. Each group was tested with compression forces by an Instron Lloyd LRX machine. The resistance to forces (N) that caused displacements of 1.75 and 3.50mm were compared using the Instron software programme and displacement graphics. There were no significant differences among the three groups for displacements of 1.75 and 3.50mm. Our study showed that the titanium miniadaptation plates, minicompression plates, and the absorbable miniplates did not differ significantly in their biomechanical behaviour.
