Immunohistochemical comparison of indermil with traditional suture materials in dental surgery.

The aim of this experimental study was to evaluate the effects of indermil on the closure of oral mucosa wounds in comparison with conventional sutures by investigating interleukin 1β (IL-1β) and tumor necrosis factor α (TNF-α) markers immunohistochemically in an animal model.The animals were anesthetized by intraperitoneal injection of ketamine (90 mg/kg body weight). Straight incisions were made to the buccal mucosa of the animals.

Effects of polyglecaprone 25, silk and catgut suture materials on oral mucosa wound healing in diabetic rats: an evaluation of nitric oxide dynamics.

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).

Intractable bimaxillary osteomyelitis in osteopetrosis: review of the literature and current therapy.

Purpose: Osteopetrosis (OP), also known as Albers-Schönberg disease, is a rare metabolic bone disease caused by a congenital defect in the development or function of the osteoclasts resulting in generalized increase in skeletal mass. Osteomyelitis is a recognized complication, and prevention of dental infections can be difficult. The locations of osteomyelitis in the jawbones have been either in the mandible or maxilla.

Use of a Simple Appliance to Prevent Mucosal Irritation by the Distractor Rod during Vertical Distraction: Case Report.

Patient discomfort due to the excessive length of the distractor rod is one of the disadvantages of alveolar distraction osteogenesis. Although this seems to be a minor complication, it can cause severe mucosal irritation on the opposite arch, and uncontrolled forces can lead to the loosening of the screws and the inactivation of the distractor. The purpose of this case report is to introduce an acrylic appliance that is very useful in avoiding the mucosal irritation caused by the long distractor rod.

Closure of palatal defects following excision of palatal pleomorphic adenomas.

Aim: The purpose of this study is to compare different palatal defect closure techniques following excision of palatal pleomorphic adenomas (PPA) in four cases and to review the associated dental literature.

Methods And Materials: Excision of all four PPA's was performed under local anesthesia. Three different closure techniques used among the cases included an intact mucosal flap, a pedicled buccal fat pad, or secondary healing.

Fixation of vertically distracted segment with dental implants after breakage of distraction device: case report.

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.

Incomplete mobilization of the maxilla resulting in failed maxillary distraction: a case report.

Maxillary distraction osteogenesis has become an accepted alternative method in the treatment of patients with severe maxillary hypoplasia in craniofacial syndromes and cleft-related deformities. Insufficient distraction, undesirable soft tissue changes, and occurrence of defective distraction vectors are among the potential complications of intraoral maxillary distraction osteogenesis. A 2-stage procedure combining maxillary advancement by distraction technique with genioplasty and mandibular setback surgery was planned to correct jaw deformities in a 22-year-old patient with severe maxillary retrusion, mandibular prognathism, and excessive lower facial height.

Total impaction of deciduous maxillary molars: two case reports.

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.

Biomechanical comparison of different plating techniques in repair of mandibular angle fractures.

Objective: The purpose of this study was to evaluate the biomechanical behaviors of different miniplate fixation techniques for treatment of fractures of the mandibular angle.

Study Design: Twenty sheep hemimandibles were used to evaluate 4 different plating techniques. The groups were fixated with Champy technique, biplanar plate placement, monoplanar plate placement, and 3-dimensional (3D) curved angle strut plate.

The effects of hemostatic agents on peripheral nerve function: an experimental study.

Purpose: In the practice of oral and maxillofacial surgery, hemostatic agents are sometimes placed in close proximity to peripheral nerves. In the present study, we evaluated immediate and delayed effects of 4 hemostatic agents (oxidized regenerated cellulose, 5% colloid silver-added gelatine sponge, bovine collagen, bone wax) on peripheral nerve function.

Materials And Methods: A total of 25 rat sciatic nerves were prepared, and the amplitudes were recorded with a physiological data acquisition system.

Biochemical and histopathological findings of N-butyl-2-cyanoacrylate in oral surgery: an experimental study.

Objectives: The increasing use of cyanoacrylates in dentistry, particularly as an adhesive and sealing glue, has raised concerns regarding its potential toxicity in humans. Several different forms of these compounds including methyl- (MCA), ethyl- (ECA), isobutyl-, isohexyl-, and octyl CA have been developed to eliminate tissue toxicity. N-butyl-2-cyanoacrylate is becoming an increasingly popular method for wound closure under low tension.

Alveolar distraction osteogenesis of bone graft reconstructed mandible.

This case report describes a patient who had severe mandibular bony deficiency as a result of excision of aggressive central giant cell granuloma. The defect was reconstructed with iliac bone graft. Four years later vertical distraction osteogenesis was performed on the grafted mandible in order to obtain a satisfactory bony height of mandibular ridge.
