1/16. Abrasion, erosion, and abfraction combined with linear enamel hypoplasia: a case report.Linear enamel hypoplasia is a developmental disturbance of enamel resulting in clinically visible horizontal defects in enamel that are present on eruption of the tooth. Nondevelopmental lesions of the hard tissues of the tooth, including carious, abrasion, erosion, attrition, and abfraction lesions, require varying amounts of time after tooth eruption to develop. Because linear enamel hypoplasia lesions are present on eruption and are exposed to the factors responsible for abrasion, erosion, and abfraction, nondevelopmental lesions could occur within them in any combination. This report describes a patient with multiple teeth with linear enamel hypoplasia lesions containing nondevelopmental defects as well as nondevelopmental defects that occurred separately. Severe pain and a unique lesion morphology were associated with the linear enamel hypoplasia defects. Affected teeth were extracted because of advanced periodontitis and were sectioned to determine the nature of the enamel and dentin lesions.- - - - - - - - - - ranking = 1keywords = periodontitis (Clic here for more details about this article) |
2/16. 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 = 10.724644215235keywords = periapical (Clic here for more details about this article) |
3/16. Talon cusp causing occlusal trauma and acute apical periodontitis: report of a case.- The talon cusp, or dens evaginatus of anterior teeth, is a relatively rare dental developmental anomaly characterized by the presence of an accessory cusp-like structure projecting from the cingulum area or cemento-enamel junction. This occurs in either maxillary or mandibular anterior teeth in both the primary and permanent dentition. One of the main problems caused by accessory cusps are occlusal interferences. The anomalous cusp even can generate occlusal trauma and reversible acute apical periodontitis of the opposing tooth. This article reports a case of talon cusp affecting the permanent maxillary left lateral incisor that caused clinical problems related to occlusal trauma and apical periodontitis caused by a premature contact. The treatment of the occlusal interference produced by the taloned tooth is described.- - - - - - - - - - ranking = 6keywords = periodontitis (Clic here for more details about this article) |
4/16. Non-Hodgkin's lymphoma disguised as odontogenic pain.A patient was treated for infraorbital swelling, nonvital teeth and a periapical lesion.

5/16. Barodontalgia due to odontogenic inflammation in the jawbone.A case is presented of severe anterior mandibular pain, which first appeared during descent of a long commercial flight, and lasted 3 d for a 28-yr-old military helicopter pilot. Apical periodontitis due to pulpal necrosis of the #31 tooth was diagnosed as the causative pathology of the pain. This pain was not ever felt in his daily routine helicopter flights, up to 6000 ft, only in the pressurized chamber of a commercial flight to 7000-ft conditions. Although barodontalgia, dental pain evoked by barometric pressure change in an otherwise asymptomatic tooth, has relatively low prevalence nowadays, it seems that periodic dental vitality tests and panoramic imaging of the jaws are worthwhile for aircrew members.- - - - - - - - - - ranking = 1keywords = periodontitis (Clic here for more details about this article) |
6/16. Barodontalgia at 12,000 feet.persons susceptible to barodontalgia include those with peridontal abscesses, carious teeth, maxillary sinus congestion, or those who have had recent extractions or restorations. A 38-year-old man had acute pain while he was in a depressurized chamber. Treatment of a periodontal abscess alleviated the problem.- - - - - - - - - - ranking = 0.0085869870331487keywords = abscess (Clic here for more details about this article) |
7/16. Does osteomalacia contribute to development of oral complications of oxalosis?Two renal dialysis patients with oral manifestations of oxalosis had undecalcified sections of iliac and alveolar bone and teeth examined histologically in an attempt to explain the development of tooth mobility and tooth loss. osteomalacia was detected in all bone specimens and attributed to aluminum toxicity after the histochemical localization of aluminum at the calcification front between osteoid and calcified matrix. aluminum was also detected histochemically in the cementum of teeth. calcium oxalate crystals were present in bone marrow, teeth, and gingiva. It is proposed that tooth mobility and tooth loss in oxalosis result from the combined effects of osteomalacia and oxalate crystal deposition within the periodontium. To prevent avoidable tooth loss it is suggested that patients with oxalosis who develop tooth mobility should have aluminum toxicity and osteomalacia excluded as causal factors.- - - - - - - - - - ranking = 0.0016833540279735keywords = alveolar (Clic here for more details about this article) |
8/16. herpes zoster infection presenting as an acute pulpitis.A major reason for referral to an endodontic practice is management of pain. Most cases are diagnosed as being of pulpal or periapical origin. However, some turn out quite differently than their initial appearance. This case report presents a patient referred to the endodontic clinic because of symptoms mimicking an irreversible pulpitis. On examination no obvious cause of the symptoms could be found. The patient was treated conservatively after which a herpes zoster viral infection was diagnosed. This case stresses the importance of a thorough investigation of all signs and symptoms and the delay of definitive treatment until a diagnosis is made.- - - - - - - - - - ranking = 2.6811610538087keywords = periapical (Clic here for more details about this article) |
9/16. chronic pain associated with a foreign body left under the soft tissue flap during periapical surgery.A case is reported of a patient who requested treatment for chronic pain of 7 yr duration. After several unsuccessful endodontic procedures, a cotton pellet was discovered under the soft tissue near the apex of the left maxillary cuspid. It was theorized that the cotton was left under the tissue flap during a previous apicoectomy procedure. After the cotton was removed the patient subsequentially reported that the pain was relieved.- - - - - - - - - - ranking = 10.724644215235keywords = periapical (Clic here for more details about this article) |
10/16. osteoblastoma in the anterior maxilla mimicking periapical pathosis of odontogenic origin.A patient with a 6-yr history of chronic orofacial pain and periapical pathosis in the anterior maxilla presented for evaluation and treatment. Previous root canal therapy had failed to resolve the persistent pain. Further evaluation suggested a non-odontogenic etiology of the patient's symptoms. Exploratory surgery revealed an osseous cavity across the maxillary anterior palatal midline filled with osteoid and early mineralized bone. The tumor was surgically removed in toto. A diagnosis of benign osteoblastoma was made.- - - - - - - - - - ranking = 13.405805269044keywords = periapical (Clic here for more details about this article) |
