“…This has been a logical first choice in testing, since surveys and personal observation had indicated that cross-brushing is practiced by the majority of dentifrice users (4,9,10). Probably cross-brushing is customary because it is easier than other technics, for it is employed in spite of the facts that other procedures are generally recommended by dentists (4,5,11,12,13,14), and that the cross-brushing method has been specifically condemned as likely to be harmful to the gingiva and cervical areas of the teeth (4,5,9,13,15,16).…”

In previous studies from this laboratory on the abrasion of dentin by brushing with dentifrice materials (1), the procedures were chosen to conform to those conditions which seemed to be present in the toothbrushing practice of the majority of dentifrice users. Toothbrushes, whole human teeth, and a crosswise brushing of the labial and lingual surfaces were employed, and under these conditions wear of exposed cementum or dentin was obtained whenever the tests were carried out with those types of dentifrices which contain abrasives.There were several details of the procedures which seemed worth further investigation. There might be some question of the influence of the brush itself in such tests, either because of its hardness or the manner in which it was used. It seemed important to ascertain the proper concentration of dentifrice to be employed in making abrasion tests, and the sites at which maximum wear takes place on the test objects. The influence of decalcification upon abrasion resistance was also studied in order to permit proper interpretation of the resultsof tests on dentifrices.The literature on abrasion testing has been reviewed in the previous paper except for the publication by Tainter and Epstein (2) which appeared recently. Their procedure makes use of human teeth and toothbrushes, but differs considerably from ours in technical details. To date their procedure has been concerned almost exclusively with enamel2 and hence a very sensitive method was needed for calipering loss by the test specimens. While the procedure has been used to a limited extent on dentin, it is not adequate for the purpose as will be hereinafter explained. PROCEDURES (a) Crosswise brushing machines. Whole teeth, toothbrushes and crosswise brushing on the labial or lingual surfaces were used as in the previous method (1), but new machines have been subsequently designed with 4 times as much capacity, and a shadowgraphic procedure has been substituted for the tedious microscopic method of measuring the depth of abrasion.

“…In CVS, 14% of patients are reported to have coronary ostial stenosis with AR [6], and about 87% of patients with coronary ostial stenosis have AR [7]. However, bilateral coronary ostial stenosis is rare [7]. Furthermore, AMI due to CVS complicated by both aortic regurgitation and bilateral coronary ostial stenosis, like our case, has been reported only once in English literature [8].…”

“…CVS is associated with aortitis, aortic insufficiency, coronary ostial stenosis, and aortic aneurysm, and patients are generally asymptomatic [5]. In CVS, 14% of patients are reported to have coronary ostial stenosis with AR [6], and about 87% of patients with coronary ostial stenosis have AR [7]. However, bilateral coronary ostial stenosis is rare [7].…”

A case of acute myocardial infarction due to cardiovascular syphilis with aortic regurgitation and bilateral coronary ostial stenosis

We report an interesting case of a 66-year-old man with acute myocardial infarction (AMI) with bilateral coronary ostial stenosis cardiovascular syphilis complicated by aortic regurgitation (AR). A 12-lead electrocardiogram and blood tests on arrival suggested AMI, and echocardiography showed moderate AR. Emergency coronary angiography showed bilateral coronary ostial stenosis. The patient underwent emergency surgical treatment, coronary artery bypass grafting, and aortic valve replacement with a bioprosthetic valve. On arrival, rapid plasma reagin and Treponema pallidum hemagglutination tests were 172.2- and 1187.5-fold, respectively. These results suggested cardiovascular syphilis, which was confirmed by pathological findings. The postoperative course was uneventful and the patient was transferred to another hospital on postoperative day 25. This patient received intravenous penicillin for 2 weeks and subsequently oral amoxicillin. When both AR and coronary ostial stenosis are found, it is necessary to consider the presence of cardiovascular syphilis.
