2/8. Deposition of calcified tissue around an overextended gutta-percha cone: case report.CASE REPORT: Root canal treatment was performed in a mandibular right second premolar with a periapical lesion and apical resorption. The root canal was prepared with K-files using the step-back technique and 3% NaOCl as an irrigant; during obturation gross overfilling of gutta-percha occurred. The tooth was permanently restored with a post and core along with a crown. Although healing of the periapical lesion occurred and the patient reported that he was symptom-free, the tooth was extracted after 4 years because of a subgingival root fracture. Following extraction the tooth was examined with SEM. The examination revealed the presence of newly formed calcified tissue at resorption sites on the root apex. This newly formed tissue extended from the surface of the root around the apex to the extruded gutta-percha cone to which it was well adapted, forming a bridge between the cone and the root.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
3/8. Reversible and irreversible painful pulpitides: diagnosis and treatment.The foregoing clinical evidence indicates that when pain is severe, or when mild to moderate pain is present with a previous history of pain in the aching tooth, with or without periapical radiolucency, the tooth is in the IRPP category. Treatment dictates endodontic therapy or extraction. On the other hand, when clinical evidence indicates that the pain is mild or moderate with no previous history of pain, normal pulp vitality, and there is no positive percussion sign, the pulp is in the RPP category. Treatment dictates indirect or direct pulp capping in teeth with or without periapical radiolucency. The success rate favours teeth with no periapical radiolucency, 98%; in teeth with periapical radiolucency the success rate is less favorable, 43%. Efforts should be made to maintain pulp vitality. Endodontic therapy can always be done, if in time the pulp develops necrosis.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
4/8. Clinical significance of the structural integrity of the superior aspect of the mandibular canal.BACKGROUND: Sparse data can be found regarding the structural integrity of the superior aspect of the mandibular canal. In many cases, the mandibular canal must be carefully evaluated prior to defining patient treatment. methods: In this case report, a 54-year-old patient presented with a periapical infection involving the mesial root of the mandibular right second molar (#31). Radiographic evaluation revealed that the periapical lesion extended from the apex of the tooth to the superior aspect of the mandibular canal. Upon surgical removal of the tooth, an apical communication between the extraction socket and mandibular nerve was located. A guided bone regeneration procedure was performed to protect the nerve from subsequent damage and to prepare the site for future implant placement. Implants were placed in the area approximately 5 months following the regenerative procedure. RESULTS: After implant placement, the patient experienced normal function and no mandibular symptomatology. Implants have been in function for the past 4 years. CONCLUSIONS: Many factors, both pathologic and developmental, can lead to a discontinuity of the superior aspect of the mandibular canal. Normally, a thin cortical plate of bone protects the nerve. When a lack of structural integrity of the canal roof is discovered, enucleation of a periapical infection or subsequent implant placement can lead to potential disruption of the nerve. Limited information is available regarding the integrity of this protective cover. This case report underscores the importance of proper clinical diagnosis before implant placement in the posterior mandible.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
5/8. Nonsurgical endodontic treatment of dens invaginatus with large periradicular lesion: a case report.The endodontic treatment of teeth with severe Type 3 dens invaginatus, characterized by an infolding of enamel and dentin, extending deep into the pulp cavity near the root apex, may be complicated and challenging. Because of the bizarre root canal anatomy and widely open apex, a combination of nonsurgical and surgical endodontic treatment or extraction is the most common choice of therapy. This article describes a nonsurgical endodontic treatment of a tooth with severe Type 3 dens invaginatus and an associated large periradicular lesion. After complete removal of the invaginated central mass of hard tissue and long-term calcium hydroxide treatment, nonsurgical endodontic treatment was performed. Complete healing of the periradicular lesion was observed at 25-month and 74-month follow-up examinations.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
6/8. Non-surgical root canal treatment of Dens invaginatus: reports of three cases.Dens invaginatus is a rare developmental malformation of teeth showing a deep infolding of enamel and dentine which may extend deep into the root. To date, conventional root canal therapy, endodontic surgery and extraction have been reported as treatment modalities, when the pulpo-dentinal complex of such teeth is affected. In the present report, non-surgical endodontic treatment of three maxillary lateral incisors with invaginatus (DI) is discussed. The Tri Auto ZX rotary system was used for shaping the root canals of two affected teeth and the Profile system was used in the third. Teeth with periradicular lesions received calcium hydroxide as an interim therapy. Two teeth were obturated with gutta percha points and AH Plus sealer using cold lateral compaction. In the third case, obturation was accomplished using a coated carrier system (Thermafil) due to the specific shape of the root canal system. Twelve months postoperatively all teeth were asymptomatic with resolution of the periapical radiolucency on two affected teeth, as confirmed radiographically. Healing was achieved without any need for further surgical intervention.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
7/8. Impacted teeth: prophylactic extractions or not?Pathologic changes related to impacted teeth are infrequent. However, considerable damage to bone and adjacent teeth may result if they do occur. Four patients are described in whom different circumstances existed with impacted teeth. Extractions are indicated when the anatomic location of the impacted teeth is most favorable and when the patient's systemic and hematologic condition is least compromising, even if the teeth are asymptomatic at that time.- - - - - - - - - - ranking = 4keywords = extraction (Clic here for more details about this article) |
8/8. Adenomatoid odontogenic tumour in a 12-year-old boy.We present a rare finding of adenomatoid odontogenic tumour (AOT) in a 12-year-old boy who was referred to the Department of Paediatric dentistry at the Eastman Dental Hospital for the extraction of a carious maxillary permanent molar. First presentation revealed that the maxillary right permanent lateral incisor and canine were unerupted. Radiological examination revealed a circumscribed radiolucent area associated with the distal aspect of the maxillary right permanent lateral incisor. The patient was admitted to our day care Unit where the carious maxillary molar was extracted and the radiolucent area associated with the maxillary right permanent incisor was explored. Pathological examination confirmed the lesion as adenomatoid odontogenic tumour. We present a brief review of the literature and consider how differential diagnosis of this tumour from more common odontogenic lesions can be established.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
