Enamel surface alterations after repeated conditioning with HCl

BACKGROUND The aim of this study was to investigate the influence of etching time with 15% hydrochloric acid (HCl) on the enamel surface destruction by studying the resulting roughness and erosion depth. METHODS The vestibular surfaces of 12 extracted, caries free human incisors were divided into four quadrants, and each quadrant was etched with 15% HCl for different numbers of etching cycles...

Bond strengths of different orthodontic adhesives after enamel conditioning with the same self-etching primer.

AIM To determine the shear bond strengths (SBS) of stainless steel brackets bonded with seven light-cured orthodontic adhesives after the enamel was conditioned with the same self-etching primer. METHODS A total of 140 extracted human molars were randomly divided into seven groups (N = 20). In all the groups, the enamel was conditioned with Transbond Plus SEP (TPSEP). Stainless steel brackets...

The in vitro effect of repeated bonding on the shear bond strength with different enamel conditioning procedures.

The aims of this study were to evaluate the effect on shear bond strength (SBS), adhesive remnant, and enamel surface of repeated bonding of new brackets on the same tooth using different methods of enamel conditioning. One hundred and thirty-five bovine incisors were used. Brackets were bonded to enamel using one of the following conditioning procedures: (1) 37 per cent phosphoric acid, (2) 37...

Enamel Surface Roughness after Orthodontic Bracket Debonding and Composite Resin Removal by Two Types of Burs

  Objective: Increased enamel surface roughness following orthodontic bracket debonding leads to increased plaque accumulation and enamel decalcification. Therefore, different methods are employed to achieve smoother enamel surfaces after bracket debonding. This study compared enamel surface roughness following orthodontic bracket debonding and composite resin removal using white stone and tung...

Alterations in Serum Enzymes after Repeated Exposure to Malathion.

The alterations in serum pseudo-cholinesterase, transaminases, and aldolase observed in 12 agricultural workers exposed to the organo-phosphorus insecticide, malathion, over a period of six months are recorded. A comparison with a series of unselected controls and a series of manual workers is made. Evidence is produced that the majority of the agricultural workers have been suffering from mino...
