ABSTRACT
The purpose of this article is to present a simple and easy method for in vitro analysis of root canal instrumentation that permits one to observe and measure the diameter of a root before and after instrumentation, using the teeth themselves as control.

Many diseases can cause orofacial pain, and the diagnosis must be established before final treatment. This case report presents a patient with orofacial pain that was diagnosed as an acute pulpitis. However, there was no evidence of this problem on examination. After 4 days, the patient showed multiples vesicles on the face, and a herpes zoster viral infection was diagnosed. The patient was treated with acyclovir and, after 2 yr, she still complains of facial sensitivity.

A series of dental outpatients in Brazil was anonymously screened for HIV antibodies in whole unstimulated saliva with an immunoglobulin G antibody-capture enzyme-linked immunosorbent assay. Salivary HIV antibodies were detected in 40 patients in the control group who were known to be HIV-seropositive but were not detected in any of a series of 40 known HIV-seronegative patients in the control group, confirming the very high sensitivity and specificity of the immunoglobulin G antibody-capture enzyme-linked immunosorbent assay. Only one patient from 84 consecutive dental outpatients of unknown HIV serostatus who were examined anonymously for HIV by immunoglobulin G antibody-capture enzyme linked immunosorbent assay showed HIV positivity (1.2% of the population).
PIP: Dental outpatients in Sao Paulo, Brazil, were anonymously screened for HIV through use of a salivary immunoglobulin G antibody-capture enzyme-linked immunosorbent assay. The ages of the 84 consecutive emergency dental patients ranged from 16 to 52 years. Pretesting of the saliva test in 40 patients confirmed to be HIV-positive through two serum assays, and 40 known HIV-seronegatives indicated this method is 100% accurate. Only 1 salivary test (1.2%) among the dental outpatients was positive for HIV antibodies. Salivary antibody testing has the advantages of absence of needlestick injuries, simplicity, ease of collection, lack of need for trained staff, greater compliance in high-risk groups, and better acceptability by children. Moreover, because of the lower titer of HIV in saliva than in blood and the HIV inhibitory action of saliva, this diagnostic method is associated with a reduced risk of occupational hazard during sample collection.

Two cases of bilateral double teeth involving the permanent maxillary central incisors are described. The difficulties in establishing the precise diagnosis are considered. The treatment plans also are discussed. The etiology and nomenclature of these dental formations and number of anomalies are reviewed.

Root canals of dogs' premolar teeth were exposed to contamination and to the development of periapical inflammation over a period of 45 days. Root canals were overinstrumented 2 mm beyond the apical foramen with file No. 60 and were underfilled by 2 to 3 mm short of the roentgenographic apex. Ninety days after endodontic treatment, healing and ingrowth of connective tissue into the root canal occurred in 67.8% of the cases. These results suggest that the diameter of the apical foramen and the intensity of the canal contamination are determining factors for periapical tissue repair in cases of pulpal necrosis.
