Pain sensation during noncarious cervical lesions preparation with air abrasion method

 

Summary:

  • Air abrasion technique enable minimally invasive preparation of noncarious cervical lesions, ensuring greater comfort of treatment and decrease pain sensation among patients. The aim of the study was to evaluate the intensity of pain during above-mentioned lesions preparation with air abrasion method. Air abrasion unit Sandman Futura / intensity of experienced pain measured with numerical scale NRS, the treatment consisted of 58 cavities.
  • Total painless was found in 74% cases with using 29 μm abrasive and in 67% cases with 45-μm abrasive. During lesions preparation with 45 μm abrasive statistically significant stronger pain than with 29μm abrasive was suffered. Air abrasion can be a method of choice for treatment of noncarious cervical lesions because of limited pain sensation while working specially with 29 μm abrasive.

 

 

Furthermore this study also shows significant higher bonding strength using low pressure air abrasion than high pressure air abrasion adding water spray.

The conclusions are based on the empiric data from this study. – The preferred method for treatment of tooth surface is using air abrasion without adding water spray.

Secondly the study shows that using the 45 micron particle size give a stronger bonding surface but using 29 micron still gives a far stronger bonding strength that the other methods and can reduce any possible sensibility.

Furthermore by using the air abrasion method the risk of micro fractures are eliminated avoiding possible well known future complications such as secondary caries and loss of fillings.

Research on bonding strength to the surface of tooth with usage of scratch test method

 

Summary:

This study confirmed the validity of the assumptions presented by manufacturers to air abrasion. In fact the bonding strength for different bond materials on the tooth surface is significant higher by using air abrasion than for conventional drilling method using a turbine.

The empiric data shows that the bonding strength increases from 72 % – 117 % between using Sandman Futura low pressure air abrasion and traditional drilling method. These figures shows that the increase is so significant that it will have major impact on dental clinic works using this method.

This result also confirms many previous studies documenting this fact. E.g. a study from Leuven Catholic University, Dental Department, 2007-2008 by Professor Van Meerbeck and Professor Lambrechts.

Furthermore this study also shows significant higher bonding strength using low pressure air abrasion than high pressure air abrasion adding water spray.

The conclusions are based on the empiric data from this study. – The preferred method for treatment of tooth surface is using air abrasion without adding water spray.

Secondly the study shows that using the 45 micron particle size give a stronger bonding surface but using 29 micron still gives a far stronger bonding strength that the other methods and can reduce any possible sensibility.

The efficacy of air abrasion technology

 

Summary:

Pits and fissures that are successfully sealed may prevent or arrest early developing occlusal lesions. Success of a sealant is related to its integrity.

Comparison of the microleakage of pit and fissure sealants after conventional bur and air abrasion preparation of the pits and fissures have shown that air abrasion tooth surfaces demonstrated less microleakage than conventionally prepared tooth surfaces.

The highly roughened enamel surface resulting from air abrasion reduces microleakages and sealant integrity affects the efficacy of air abrasion.

Investigating the efficacy of air abrasion technology the teeth were roughened with air abrasion that sealant was applied without acid, omitting a step in the bonding procedure.

The omission of the acid etch and subsequent drying steps resulted in one-third less chair-time in comparison with sealants placed conventionally with acid etching.
