BVD is recognised as one of the most economically important endemic diseases of cattle. Bovine Viral Diarrhoea (BVD) is caused by the bovine viral diarrhoea virus (BVDV). The genus Pestivirus of the family Flaviviridae consists of four recognised species: Bovine viral diarrhoea virus type 1 (BVDV-1), Bovine viral diarrhoea type 2 (BVDV-2), Border disease virus (BDV) and Classical swine fever (CSF) virus . Pestiviruses are single stranded positive-sense RNA viruses. Although the natural host for BVDV is cattle, it can also affect sheep and wild animals, including deer and pigs. BVD is recognised as one of the most economically important endemic diseases of cattle.
Often, an electric device, known as an ultrasonic, sonic scaler, or power scaler may be used during scaling and root planing. Ultrasonic scalers vibrate at a frequency to help with removing stain, plaque and calculus. In addition, ultrasonic scalers create tiny air bubbles through a process known as cavitation.
This is how different hand scalers are from ultrasonic scalers. There are many brands on the market with a wide variety of features that determine clinical usage and the final clinical outcome for the patient.n my opinion it would be difficult, if not impossible, for most clinicians to put their hand scalers aside completely, but the tables are turning as the evidence mounts in favor of an ultrasonic scaler as our primary weapon against biofilm-based dental disease.
