Various anomalies in the size, shape, number, structure and eruption of the teeth are often observed clinical conditions. Supernumerary teeth can be found in almost any region of the dental arch, and most of the times they are asymptomatic, and are routinely found during radiographic evaluation. The most common cause of impacted maxillary incisors is the presence of the supernumerary teeth. This paper describes a case of multiple supernumerary teeth associated with an impacted permanent maxillary central incisor in an 11-year old child along with its surgical and orthodontic management. 相似文献

Primary atonic post-partum hemorrhage during lower segment cesarean section, which was not controlled by ecbolics--oxytocin, methylergometrine, 15-methyl-prostaglandinF2alpha--was managed by applying a B-Lynch Brace Suture. The test of potential efficacy was the control of hemorrhage by bimanual uterine compression. Six primigravida patients at their term gestation, who underwent emergency cesarean section, all except one under spinal anesthesia, received this type of suture. Interestingly, in every case hemorrhage was controlled successfully with the compression suture. None of them received blood or blood products transfusions or developed disseminated intravascular coagulopathy. Postoperative recovery was good and all patients are in follow-up to assess their future reproductive activity. B-Lynch Brace Suturing is an invaluable procedure for the control of atonic primary post-partum hemorrhage following cesarean delivery. 相似文献

Accidental foreign body ingestion or aspiration is a common problem in children. Children often have a habit of inserting objects into their mouth. Some of these objects can be accidentally ingested or even aspirated which can be frightening and a stressful experience. But the presence of foreign objects in the teeth are rare. The foreign objects in the teeth may act as a potential source of infection and pain. In most of the cases, children avoid informing their parents due to fear of punishment. This paper presents two cases of foreign objects embedded in the deciduous teeth. In both the cases, parents were not aware of foreign body ingestion by their children. 相似文献

BACKGROUND & AIMS: Transient lower esophageal sphincter relaxation is the main mechanism for gastroesophageal reflux. Although there is evidence that transient lower esophageal sphincter relaxations are neurally mediated, another school of thought is that transient lower esophageal sphincter relaxations result from gastric distention, which shortens the sphincter to the point where it opens and the pressure decreases. We assessed the relationship of transient lower esophageal sphincter relaxation to gastroesophageal junction opening in an unsedated human model. METHODS: Seven healthy volunteers (6 men and 1 woman, aged 18-53 years) were studied while they were sitting. Manometry was performed by using a sleeve catheter passed through 1 nostril. A 5.3-mm endoscope was placed through the other nostril to obtain a retroflexed view of the cardia. The biopsy channel was connected to a barostat to distend the stomach with air at 15 mm Hg for 30 minutes. Manometric and endoscopic video-recording times were synchronized but scored independently. RESULTS: The transient lower esophageal sphincter relaxation onset invariably preceded gastroesophageal junction opening (median, 5.0 seconds; range, 0.5-20.7 seconds; P < .001). The transient lower esophageal sphincter relaxation nadir also typically occurred before gastroesophageal junction opening (median, 2.1 seconds; range, -4.2 to +19.5 seconds; P < .001). Once open, the gastroesophageal junction moved proximally for the duration of the transient lower esophageal sphincter relaxation. Termination of transient lower esophageal sphincter relaxations occurred about the time the time of gastroesophageal junction closure. CONCLUSIONS: These data refute the hypothesis that transient lower esophageal sphincter relaxations result from passive mechanical distraction of the gastroesophageal junction. Rather, transient lower esophageal sphincter relaxations must occur before the gastroesophageal junction can open. 相似文献

Burns can leave a patient with a severely debilitating disability even after treatment. The objectives of burn rehabilitation are to minimize the adverse effects caused by the injury while rehabilitating the patient''s physical and psychological well-being, maximizing social integration. Long-term success of maxillofacial prostheses mainly depends on the retention. Extra oral implant retained prostheses have proved to be a predictable treatment option for maxillofacial rehabilitation. Replacement of a severely deformed external ear with burned tissues may be satisfactorily accomplished by a cosmetic prosthesis anchored by implants integrated in the skull. The use of such implants is now a well-recognized method for creating a stable result in maxillofacial rehabilitation. This case report describes a safe, simple and economical method for the rehabilitation of a patient with missing right auricle using an implant supported silicone prosthesis. The implant was placed in the mastoid region of the temporal bone. Reconstruction of the ear was done with auricular silicone prosthesis, retained using magnets incorporated in an autopolymerizing resin shim to decrease the weight of the prosthesis on a single implant. This method eliminates the need of tedious laboratory procedures and exact casting and fitting requirements of a metal substructure while minimizing the overall weight and cost of the prosthesis while maintaining adequate support, esthetics and retention of the prosthesis. 相似文献

Carcinomas of the tongue constitute approximately 5% to 10% of oral carcinomas. Rehabilitation of these patients postsurgery is challenging because the motor control of the tongue is lost and postsurgical scarring reduces the vestibular depth needed to support and retain a denture. Implant-supported overdentures are a viable option to rehabilitate such patients. The restoration provides enhanced function and wearer comfort. 相似文献

Cyanoacrylates are tissue adhesives used for closure of surgical wounds. N-butyl cyanoacrylate is a biocompatible tissue adhesive used for closure of surgical wounds. In the present study evaluation and comparison the healing of oral wounds was done when closed with N-butyl cyanoacrylate and silk sutures in a rabbit model. It was found clinically that the sites treated with cyanoacrylate had less inflammation and healed better at 7 days as compared to the sutured sites. At 7 days the histological picture correlated with the clinical findings and the amount of inflammation was less on the cyanoacrylate site. At 21 days both the sites appeared similar clinically and histologically. It is concluded that N-butyl cyanoacrylate tissue adhesive results in faster initial wound healing as compared to silk sutures and can be used for closure of oral wounds. 相似文献
