Abstract:
Background: Periodontal disease is considered one of the main pathologic diseases
occurring in humans. The use of Diode laser in treatment of periodontitis is an
innovative opportunities .
The aim of study: is examining the new challenging indications of this modern
technology for the daily practice of periodontology as new and efficacious
alternativefor chronic periodontitis treatment, And comparing its effectiveness with
the antimicrobial effect of two newly extracted menthe oils (M. pipperita and
spearmint oil).
Methods: Subgingival plaque samples from fifteen cases with severe chronic
periodontitis were analysed. From each case five samples were
collected;control(without treatment), and the other four samples were subjected to
alternative conditions of radial firing tip with 1.5 W, or 2Wwith 11% air, 20% water,
and pulse duration 60 sec.or 90 sec.. Pocket depths of all periodontal sites were
measured.Microbiological smear on blood agar were examined to compare reduction
in bacterial count with each condition.In addition antimicrobial effect of each oil
Detected
Results: showed that 96.79%.of samples exposed to the combined condition of 2 W
pulse duration 90 sec.showed the least reduction in bacterial count .Followed by those
exposed to 2W for 60sec.where bacterial growth reduced in 96.85% of
samples.Bacterial growth shown in 95.11% of samples exposed to1.5Wfor 90
sec.Antimicrobial activity of M. pipperita oil was effective against periodontic
pathogens in 71.4% of cases ,where as Spear mint had no Antimicrobial activity.
In conclusion: Use of diode laser supports effective treatment of periodontitis and
showed a significant reduction of periodontopathic bacteria more than other methods
which can maintain good periodontal health.
