the incidence of stone disease among patients with congenital renal anomalies including malrotated kidney is more than in normal population due to poor urine drainage and stasis (1). various minimally invasive options have been used for the management. ureteroscopy and holmium:yag laser lithotripsy have been reported with favorable outcomes (2). we report a 30-year-old male who presented to our...

background and aims. previous researches, conducted mostly on extracted teeth, have shown that efficacy of calculus removal decreases with increasing pocket depth, but there is still a lack of clinical studies concerning the correlation be-tween residual calculus and varying pocket depths. the objective of the present clinical study was to assess the efficiency of mechanical tooth depuration by...

 Gingiva is a common region of inflammatory and reactive lesions. Systemic conditions, including hormonal imbalance in pregnant women, may cause exaggerated response to irritations such as calculus or infection.

Although there are many excellent ways presenting the principle of the classical calculus, the novel presentations probably leads most naturally to the development of the non-Newtonian calculus. The important point to note is that the non-Newtonian calculus is a self-contained system independent of any other system of calculus. Since this self-contained work is intended for a wide audience, inc...
