1/13. prognosis of replanted primary incisors after injuries.Between 1979 and 1997, 58 avulsed primary teeth were treated at the Pedodontic Clinic of Niigata University Dental Hospital. Among these, we replanted six avulsed incisors of four patients and treated two teeth of two patients replanted at other dental clinics. Referring to the clinical records, oral photographs and radiographs, we examined the injury age, cause of injury, condition of tooth storage, length of time until replantation, and also the prognosis after replantation. Three teeth of two cases remained until eruption of their permanent successors, and one tooth of one case remained under observation without extraction. Although the other four teeth of three cases resulted in extraction, no secondary infection was detected due to replantation. The following reasons were suspected for the poor prognosis of the four teeth. One avulsed tooth was not fixed immediately after replantation. One replanted tooth might not have been compatible with the alveolar socket. In the other two teeth, the periodontal vital tissues might have been removed before replantation. It is generally suggested that replantation of primary teeth is not a good option. However, from the present results, it was considered that replantation can be an effectual method when the condition of the avulsed primary tooth is suitable.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/13. Decoronation of an ankylosed tooth for preservation of alveolar bone prior to implant placement.A 12-year-old patient sustained avulsions of both permanent maxillary central incisors. Subsequently, both teeth developed replacement resorption. The left incisor was extracted alio loco. The right incisor was treated by decoronation (removal of crown and pulp, but preservation of the root substance). Comparison of both sites demonstrated complete preservation of the height and width of the alveolar bone at the decoronation site, whereas the tooth extraction site showed considerable bone loss. In addition, some vertical bone apposition was found on top of the decoronated root. Decoronation is a simple and safe surgical procedure for preservation of alveolar bone prior to implant placement. It must be considered as a treatment option for teeth affected by replacement resorption if tooth transplantation is not feasible.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
3/13. Extraction as a treatment alternative follows repeated trauma in a severely handicapped patient.Handicapped patients with protruding maxillary incisors are prone to repeated dental trauma. A 13-year-old girl with cerebral palsy, severe mental retardation and seizure disorder was referred to our department for restoring the traumatized anterior teeth. Despite drug combination, the frequency of seizure attack was around 10 times a month. The oral examination showed multiple caries, gingival hyperplasia, class II malocclusion with 14 mm overjet and deep overbite. During the first 3 years of a 7-year follow-up period, six episodes of anterior tooth trauma due to seizure attack occurred. The trauma-related treatment performed included endodontic therapy, multiple composite restorations, apical repositional flap, and finally extraction of all four upper incisors with fabrication of a semi-fixed band-retained denture. The denture restored normal overbite and overjet with improved esthetics. For 4 years following the fabrication of denture, no trauma occurred to the anterior teeth in later seizure attacks. Considering inadequate control of seizure disorder, little ability of the patient to receive comprehensive orthodontic treatment, poor prognosis of restorations, and possible future injuries, the removal of non-functional, nonesthetic, trauma-susceptible incisor teeth can be justified as an alternative to tooth preservation.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
4/13. Lingual displacement of an entire lower third molar. Report of a case with suggestions for prevention and management.Perfect knowledge of regional anatomy is the main factor in the prevention of tooth displacement during lower third molar extraction. Some technical expedients should be used to avoid the occurrence of this accident and to manage it if it anyway happens. The patient was seen just 2 days after his left lower third molar was lingually displaced during surgical extraction. Two mucoperiosteal flaps were made under general anaesthesia, one on each side of the mandible, to obtain good exposure of the previous bone access and to retrieve the tooth. No further complications occurred. Lower third molar extraction becomes complicated if tooth displacement happens. Predisposing factors of this accident are analyzed and the rules to minimize the risk of its occurrence and to simplify the retrieval of the displaced tooth are discussed.- - - - - - - - - - ranking = 1.5keywords = extraction (Clic here for more details about this article) |
5/13. Complete tooth extraction: a case report.Advanced Trauma and life Support protocol is used in trauma situations to identify life-threatening injuries, and after those are addressed, it provides a systematic approach to identify minor injuries. A 17-year-old male, who was involved in a motor vehicle accident, was treated for an open toe fracture. He also had an "avulsion injury" to his left hand and was missing a tooth. On follow-up two days later, he was found to have a tooth in his left hand after he presented with cellulitis of a hand wound. He was appropriately treated with foreign body removal, incision and drainage, and antibiotics. This case is not only presented for being unique but also to emphasize the importance of the secondary survey and serial examinations instructed by Advanced Trauma and life Support.- - - - - - - - - - ranking = 2keywords = extraction (Clic here for more details about this article) |
6/13. Self-inflicted orodental injury in a child with leigh disease.leigh disease is an inherited progressive mitochondrial neurodegenerative disease that affects the neurological, respiratory and cardiovascular systems and is associated with retardation of the intellectual and physical development. This report describes the case of a 4-year-old boy with leigh disease who presented with self-inflicted traumatic injury to the teeth, alveolar bone, lips and tongue during repeated episodes of intense orofacial spasms. Conservative management of the injury included repositioning the fractured alveolar bone, splinting the traumatized teeth and planning for a mouthguard. However, after a second incident of severe self-induced injury to the teeth and alveolar bone, extraction of the anterior teeth became inevitable to protect the child from further self-mutilation and to allow healing of the injured tissues.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
7/13. Treatment of avulsed teeth with Emdogain--a case report.The present case report describes the reimplantation of avulsed teeth with the treatment of Emdogain. Case was avulsed right maxillary permanent central and lateral incisor in a 9-year-old girl suffering from a traumatic injury. After pretreatment of avulsed teeth, Emdogain was applied to the root surface and into the extraction socket with subsequent replantation of the tooth. Evaluation parameters included horizontal and vertical percussion sound and periapical radiographs. At 1-2-6-12-month follow-up period, the clinical and radiographic appearance of the teeth showed resolution of mobility and no signs of replacement resorbption.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
8/13. A case of tourette syndrome presenting with oral self-injurious behaviour.Self-injurious behaviour (SIB) is deliberate harm to the body without suicidal intent, and the condition occurs in a number of psychiatric, behavioural and developmental disorders. This case report describes a 4-year-old female with SIB who presented to a paediatric dentist after the self-extraction of teeth as a result of oral motor tics. The girl repetitively ground her teeth in a monophasic lateral motion that resulted in luxation of her maxillary right primary canine, and produced generalized oral and facial pain. The parents consulted the dentist about their child's complaint of toothache. The oral findings were unexcephonable except for a mobile primary canine, but there was a history of unusual behaviour including hyperactivity, and after multidisciplinary consultation and exclusion of other systemic diseases, the subject was diagnosed as suffering from Tourette syndrome (TS). Preventive treatment using a dental splint was provided. Noncontingent reinforcement therapy was successfully used to diminish the subject's SIB.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
9/13. Congenital insensitivity-to-pain with anhidrosis (CIPA): a case report with 4-year follow-up.Congenital Insensitivity-to-pain with anhidrosis (CIPA) is a rare disorder in which pain perception is absent from birth, despite the fact that all other sensory modalities remain intact or minimally impaired and tendon reflexes are present. The challenge in dentistry is to manage the self-mutilation behavior avoiding serious damages especially to oral structures, hands and fingers. A Brazilian case of CIPA is presented and discussed with clinical documentation of the oral-related problems over a 4-year follow-up. A conservative treatment (mouthguard-like appliance) was proposed with the objective to avoid full mouth extraction.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
10/13. Immediate esthetic treatment of an avulsed/replanted permanent incisor with extensive root resorption: a case report.This article describes the treatment of a 10 year-old patient with complete root resorption of the maxillary permanent incisor following avulsion and replantation 4 years earlier. The remaining natural crown was used to immediately solve the esthetic problem created by its extraction. The crown was attached with an orthodontic wire and composite resin to adjacent teeth. This temporary treatment does not elicit any damage to adjacent teeth, and can be easily removed. Therefore, it does not affect any plans that might be considered in the future as the permanent treatment.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
