Diagnosis and possible causes of vertical root fractures.

Thirty-two cases of vertical fractures were studied in an attempt to identify the causes and diagnostic signs normally present. In all of the patients except two, osseous defects were present and could be probed. The majortiy (65.63 percent) had only mild pain or a dull discomfort. Seventy-five percent showed diffuse widening of the periodontal ligament space. This study suggests that excessive force during lateral condensation of the gutta-percha caused 84.38 percent of the fractures. A secondary cause was the forcing or tapping of inlays or dowels into place. The majority (78.13 percent) of the patients were over the age of 40. In all but nine of the cases, treatment consisted of the extraction of the involved teeth.

Endodontic perforations which resulted in alveolar bone loss. Report of five cases.

Five cases in which perforations of mandibular molars into the furca occurred during endodontic instrumentation of the canal are presented. This resulted in alveolar bone loss. All were relatively asymptomatic, which could present a problem in diagnosis of the periodontal defect. The prognosis is questionable. The only tooth retained was treated surgically by an apically positioned flap and opening of the furca area to make it accessible to cleansing. The best treatment is the avoidance of the perforation. This is accomplished by considering the configuration of the canals and the size of the reamer than can follow it. Overinstrumentation with an endodontic instrument that is too large in diameter should be avoided.

Primary herpetic gingivostomatitis accompanying lesions on fingers: report of case.

A case is presented of primary herpetic gingivostomatitis with herpes simplex virus infection involving the right thumb and little finger of an 18-year-old white man. The lesions all started at the same time. The disease was allowed to run its course except for symptomatic treatment. The diagnosis was made both from clinical signs and laboratory isolation of the virus.

Alveolar bone loss associated with vertical root fractures. Report of six cases.

Six cases of vertical root fractures accompanied by vertical bone loss are presented. Possible causes for these fractures are suggested. Four vertical fractures probably resulted from the use of excessive pressure at the time of obturation of the canals. One vertical root fracture may have been caused by the cementation of a post, and another may have been caused by the cementation of an inlay in an endodontically treated tooth. All of the fractures resulted in alveolar bone loss to the apical extent of the fracture lines. The definitive treatment in each case was extraction of the tooth or root amputation. In one case successful treatment was accomplished by apically positioning the flap.
