Principles and practice of operative dentistry . Fig. 618.—Salivary calculus. Fig. 619.—Salivarv Fig. 620.—Glands of Series. ,\ 50. DEPOSITS UPON THE TEETH. 597 upon the cervices of the teeth in the form of isolated islands, usually uponthe lingual surface or in the form of a narrow band directly beneath thefree margins of the gums. It is generally dark green or brown in color,very hard, brittle, and tenacious, requiring in some instances considerableforce to dislodge it. This variety of calculus is most often found in themouths of robust individuals, in those who live high, and those withrheumatic and gouty tendencies. The pathologic effect of this variety of calculus is to establish a lowgrade of chronic inflammation of the gums, ulceration of the gingival mar-gins, resorption or necrosis of the margins of the alveoli, and recession ofthe gums. These conditions are the result of the mechanic irritation pro-duced by the impingement of the calculus upon the margins of the gumsand the pericementum. Acute inflammatory symptoms are rarely presented in this form ofsalivary calculus
