1/16. Delayed apical healing after apexification treatment of non-vital immature tooth: a case report.We report the endodontic treatment of a non-vital permanent immature tooth in which unexpected complications such as exacerbation of apical periodontitis followed by external root resorption occurred after that the initial stages of the healing process were clinically and radiographically evident. After continued treatment stable repair was obtained.- - - - - - - - - - ranking = 1keywords = process (Clic here for more details about this article) |
2/16. Implant periapical lesion: a clinical and histologic case report.A new pathologic entity called implant periapical lesion has been recently described. This lesion could be produced by contamination of the implant surface, overheating of bone, overloading of the implant, presence of a pre-existing bone pathology, presence of residual root fragments and foreign bodies in bone, implant placement in an infected maxillary sinus, implant placement in a poor bone quality site, or lack of biocompatibility. A 49-year-old female patient underwent the placement of a screw-shaped titanium dental implant in the premolar region of the right mandible Six months after implant insertion, the patient presented with a persistent pain resistant to analgesics. No fistula was present at a clinical intraoral examination. A periapical x-ray showed the presence of a radiolucency at the apical portion of the implant; this image was confirmed by a CT Scan. The implant was removed. After implant removal, the pain disappeared completely. The specimen was processed to obtain thin ground sections. The histologic examination showed the presence of necrotic bone in the external and apical portion of the antirotational hole of the implant. The etiology of the implant failure in this instance could be related, probably, to an implant contamination of the apical portion of the implant.- - - - - - - - - - ranking = 1keywords = process (Clic here for more details about this article) |
3/16. Delayed eruption of premolars with periodontitis of primary predecessors and a cystic lesion: a case report.Apical periodontitis after pulp therapy in a primary tooth can cause delayed eruption of the permanent successor. A case of bilateral delayed eruption of mandibular premolars is presented. The patient. a 13-year-old girl, was referred by her dentist. Oral findings showed that the right first and left second primary molars were retained. Other premolars had erupted. An orthopantomogram revealed apical periodontitis, affecting both retained primary molars. The right first mandibular premolar was impacted against the alveolar bone and root of the second premolar, and there was a large cystic lesion in close association with the left second mandibular premolar. Both primary molars were extracted, and the cystic lesion was treated by marsupialization. Fenestration and traction were performed on the right first premolar. Correct tooth alignment was achieved with orthodontic appliances. If the problem had been detected earlier, treatment of the premolars might have been easier. Clinical and radiological follow-up, therefore, of primary teeth that have undergone pulp therapy procedures should be performed until eruption of succedaneous teeth.- - - - - - - - - - ranking = 265.14286342422keywords = alveolar (Clic here for more details about this article) |
4/16. Hemisection for treatment of an advanced endodontic-periodontal lesion: a case report.AIM: To emphasize the importance of primary endodontic treatment when dealing with endo-perio lesions and to demonstrate the considerable healing potential of the endodontic aspect. CASE REPORT: After several years of unsuccessful symptomatic periodontal treatment, an advanced endo-perio lesion on a right-mandibular first molar was successfully treated by root-canal treatment and hemisection after the re-evaluation of the lesion. This successful treatment appeared to have a positive effect on the patient's general well-being. KEY learning POINTS: The origin of a combined endo-perio lesion is indicated by its clinical and radiographic appearance. The periodontal situation is often misinterpreted. The prognosis for the endodontic element of treatment is excellent. Local pathologic processes in the oral cavity may affect a patient's general health.- - - - - - - - - - ranking = 1keywords = process (Clic here for more details about this article) |
5/16. Endoperiodontal lesion. A case report.The purpose of this case report is to present an unusual endoperiodontal lesion on tooth 46 in an 8-year-old child. The absence of any carious process and the presence of the typical radiographic aspect of an infrabony defect, led us to consider the periodontal aetiopathogenesis. In spite of all this, an accurate periodontal probing of all the teeth and the use of the pulp tester for teeth 46 and 36 led us to diagnose properly a truly endodontic lesion. The endodontic treatment of the involved tooth achieved the complete healing of the lesion.- - - - - - - - - - ranking = 1keywords = process (Clic here for more details about this article) |
6/16. Secondary hyperparathyroidism: a case report.A thorough diagnostic examination is essential before providing endodontic treatment. The sequence of diagnostic procedures must begin with a well-organized review of the medical history. In the early screening process, a health history that reveals a systemic disorder must be investigated further because it may have a significant impact on the dental diagnosis and ultimate endodontic treatment. There are a number of systemic diseases that can cause bone lesions throughout the body. Chronic renal failure is one disorder that may stimulate a secondary hyperparathyroidism that can cause a variety of bone lesions. In some instances these lesions appear in the periapical region of teeth and can lead to a misdiagnosis of a lesion of endodontic origin. The following case report of a patient referred for endodontic treatment demonstrates the importance of understanding the effects of end-stage renal disease on the dental structures.- - - - - - - - - - ranking = 1keywords = process (Clic here for more details about this article) |
7/16. Localized vertical maxillary ridge preservation using bone cores and a rotated palatal flap.The aim of vertical augmentation of the alveolar ridge is to restore resorbed alveolar ridges. This technique is critical to the placement of dental implants in a favorable position and the enhancement of restoration esthetics. The present report describes a technique for surgical preservation of the anterior maxillary process using maxillary bone from the surgical site and raising a soft tissue rotated palatal flap. Maxillary lateral incisor extraction and periapical surgery of the central incisors were first carried out. Two bone cores were harvested from the neighboring buccal vestibular region and placed in the sockets of the lateral maxillary incisors. After 3 months, implants were placed; 12 weeks later, the prosthetic restorations were cemented. There were no complications after 2 years of follow-up. This technique constitutes a viable approach for preserving the anterior sector alveolar ridge with the posterior placement of dental implants.- - - - - - - - - - ranking = 1704.3095206688keywords = alveolar, ridge, process (Clic here for more details about this article) |
8/16. Management of periodontitis associated with endodontically involved teeth: a case series.The pulp and the periodontal attachment are the two components that enable a tooth to function in the oral cavity. Lesions of the periodontal ligament and adjacent alveolar bone may originate from infections of the periodontium or tissues of the dental pulp. The simultaneous existence of pulpal problems and inflammatory periodontal disease can complicate diagnosis and treatment planning. The function of the tooth is severely compromised when either one of these is involved in the disease process. Treatment of disease conditions involving both of these structures can be challenging and frequently requires combining both endodontic and periodontal treatment procedures. This article presents cases of periodontitis associated with endodontic lesions managed by both endodontic and periodontal therapy.- - - - - - - - - - ranking = 266.14286342422keywords = alveolar, process (Clic here for more details about this article) |
9/16. Peri-implant pathology caused by periapical lesion of an adjacent natural tooth: a case report.An implant was removed 6 months after restoration because of peri-implant pathosis. The implant had been placed adjacent to the mandibular right second premolar and close to a periapical lesion of the endodontically treated adjacent first premolar. Along with removal of the failed implant and an apicoectomy of the problem tooth, guided bone regeneration was used to restore the alveolar ridge defect at the site of the failed implant. A replacement implant was placed 6 months later and successfully restored after healing.- - - - - - - - - - ranking = 394.84013919511keywords = alveolar, ridge (Clic here for more details about this article) |
10/16. abscess of the orbit arising 48 h after root canal treatment of a maxillary first molar.AIM: To discuss a rare, but severe complication arising following routine root canal treatment. SUMMARY: An orbital abscess is reported that occurred following routine root canal treatment. A young, healthy female patient, with no history of chronic paranasal infection had undergone root canal treatment of the right maxillary first molar. On hospital admission, she presented with extensive periorbital swelling and discreet diplopia. Computed tomography imaging identified massive purulent sinusitis and subsequent involvement of the orbit via the inferior and medial orbital wall within 48 h after completion of root canal treatment. Immediate surgical drainage of the maxillary sinus and the orbit was established and a high dose of perioperative antibiotics (amoxicillin/Clavulanic acid, Gentamycin, metronidazole) were administered. Vision remained undisturbed and mobility of the globe recovered within 10 days. KEY learning POINTS: Rapid exacerbation of a periapical inflammation may occur following root canal treatment and may even involve the orbit. A typical speed of disease progression or ophthalmic symptoms should alert the clinician to at least consider unusual early orbital spread of odontogenic infection. When extra-alveolar spread and especially orbital spread is suspected, immediate referral to a maxillofacial or other specialized unit is mandatory.- - - - - - - - - - ranking = 265.14286342422keywords = alveolar (Clic here for more details about this article) |
