📌 POINTS TO PONDER 

🔹Reversal phenomenon is the decline from maximal calculus accumulation. It is due to vulnerability of bulky calculus to mechanical wear from food, cheeks, lips and tongue. 

🔹Calculus can also occur readily in germ free animals. 

🔹Calculocementum is the calculus embedded deeply in the cementum and which appears morphologically similar to cementum. 

🔹Calculus is the most prominent plaque retentive factor and is a secondary etiologic factor for periodontitis.

🔹It can also occur readily in germ-free animals.
