SIDS plane: A simple and innovative alternative to Frankfurt horizontal plane.

Aims And Objectives: To derive a new horizontal plane which can be a suitable alternative to Frankfurt horizontal plane (FH plane).

Materials And Methods: 200 pre-treatment lateral roentogenic cephalograms from patient records in the department of orthodontics and dentofacial orthopaedics were traced. The landmarks were identified and marked and the measurements were carried out.

Effect of ER, CR: YSGG laser debonding on enamel surface changes in stainless steel and ceramic brackets - An study.

Aim: The aim of this in-vitro study was to observe and analyze the various enamel surface changes that occur due to laser debonding of metal and ceramic brackets, done by means of Er, Cr:YSGG laser.

Materials And Methods: 90 extracted premolars were randomly allocated into one of six groups with 15 teeth each. The groups represent metal brackets (Groups A1, A2, A3) and ceramic brackets (Groups B1, B2, B3).
