This work aims to evaluate the clinical efficacy of low and high output power of a 980 nm diode laser in the treatment of dentin hypersensitivity.
Twelve teeth were selected having dentine hypersensitivity. Dentin hypersensitivity (DH) was assessed by tactile and thermal stimuli and measured by visual analogue scale
(VAS) Teeth were randomly divided into two groups namely: group A, treated with high power diode laser of 1 W and group B, treated with low power of 500 mW. A 980 nm diode laser was used for duration of 60 second. Teeth from both groups were subjected to one laser session. Dentin hypersensitivity was measured before and after laser application by 15 minutes and again evaluated after one week.
The obtained results for both groups, (before versus after 15 minute of laser sessions) showed a significant reduction in VAS scores (p-value < 0.05). Intergroup comparison showed that reduction in VAS scores was significantly high in group A. However, the comparison between after 15 minutes versus one week, mean reduction in VAS scores decreased in the two groups may indicate slit recurrence of hypersensitivity.
This study shows that a 980 nm diode laser with high output power of 1 W can be used effectively in providing immediate relief in severe cases of dentin hypersensitivity and still better after one week.

Background: The acute, non-spontaneous, short- or long-lasting nature of pain due to hypersensitivity that appears suddenly on stimulation warrants a therapeutic mode which would bring about a significantly greater, immediate reduction of dentinal hypersensitivity. Lasers may now provide reliable and reproducible treatment for this condition.
Objectives:the present study aimedto assess the immediate and long-term efficacy of diode laser in the treatment of dentinal hypersensitivityand to compare the efficacy of diode laser and 5% potassium nitrate gels in the treatment of dentinal hypersensitivity.
Subjects and methods:eighteenteeth diagnosed with dentine hypersensitivity were included in this split mouth study, and teeth were randomly divided equally into two groups: group A, which received treatment with GaAlAs (diode) laser, andgroup B, treated with desensitizer 5% potassium nitrate gel. DH was assessed by means of an air stimulus, and a visual analogue scale (VAS) was used to measure DH. The selected teeth in group A received laser therapy for one session. teeth subjected to diode-laser treatment were irradiated at 100 mW for 25 sec at 810 nm, with continuous-emission, noncontact mode, perpendicular to the surface, with scanning movements on the region of exposed root surfaces
Results:immediately. after the laser was applied, we observed an overall reduction in theresponse to air blast of 44.9% (mean 3.00, SD1.732) in group A, three times greater than that observed in the group B, which was 17.5% (mean 1.11, SD 0.928), after 10 days the reduction in VAS in the laser group was 58.3% (mean 3.89, SD1.616) which was more than the reduction in VAS observed in 5% potassium nitrate gel group which was 36.8%(mean 2.33, SD 1.871). both groups showed significant decrease between baseline and 10 days with pronouns effect on group A
Conclusions:A reduction of DH was recorded immediately and after 10 days in both groups(A and B), better results were noted in group A whencompared to group B.

To Evaluate The Effect Of Diode Laser As An Adjunct To Scaling And Root Planing In Treating Periodontitis Stage Iii

Periodontal disease is a chronic inflammatory multifactorial disease with microbial plaque and calculus being the prime factors.As the dental plaque biofilm accumulates, different bacterial species may colonise and develop into a biofilm. The subgingival plaque comprises of a complex microbiota consisting mainly of gram-negative anaerobic bacteria. The microorganisms most often detected at high levels include A. actiniomycetemcomitans, P. gingivalis, T. forsythia, and T. denticola.
The goals of periodontal treatment include the arrest and control of infection, removal of plaque and calculus, reduction in the amount of bioburden within the pocket, and providing an environment where the tissue can return to health.
The initial phase of treatment is SRP, which is considered as the gold standard. However, some microorganisms remain on the root surface even after root planing and scaling procedures.
LASER" is an acronym for "Light Amplification by Stimulated Emission of Radiation". The laser properties of monochromaticity, directionality and coherence make lasers unique and suitable for applications in the medical and dental fields
The Diode laser does not interact with dental hard tissues making it convenient for soft tissue operations, cutting and coagulation of gingiva, soft tissue curettage, or sulcular debridement
AIMS AND OBJECTIVES
This study aims to evaluate the effect of diode laser as an adjunct to SRP in treating periodontitis stage III based on periodontal parameters.
MATERIALS AND METHOD:
A randomised clinical trial with a split-mouth design was conducted. The clinical parameters of pocket depth plaque index, gingival index and clinical attachment loss level are measured at the baseline
Half of the mouth (right side)was treated with scaling and root planning alone, and the other half (left side) was treated with scaling and root planning and laser therapy and; measure the clinical parameters after one month
RESULTS:
The meanplaque index on the right side at baseline was 1.25and after one month was 0.16. The mean gingival index on the right side at baseline was 1.16, and after one month was0.3. The Mean pocket depth on the right side at baseline was 1.6 and after one month was 1.4.Clinical attachment loss on the right side at baseline was 2.9 mm, and after one month was 1.9 mm. The meanplaque index on the side at baseline was 1.05 and, after one month, was 0.05. The mean gingival index on the left side at baseline was 1.3, and after one month was0.08. Mean pocket depth on the left side at baseline was 2.0 mm and after one month was 0.5 mmClinical attachment loss on the left side at baseline was 2.7 mm and after one month was 1.01 mm.
CONCLUSIONS:
There is a reduction on both sides in all parameters, but on the side laser, more than the scaling and root planing only

Effectiveness of Diode Laser (808 nm) for Excisional and Incisional Biopsies of Oral Lesions
Abdalla, Luay Ahmed; Supervisor, -Elhadi Mohieldin Awooda; Co- Supervisor, -Sohad Sa'ad Elwakeel
Lasers have made a tremendous progress in the field of dentistry and have turned out to be crucial in oral surgery as collateral approach for soft tissue surgery. This rapid progress can be attributed to the fact that lasers allow efficient execution of soft tissue procedures with excellent hemostasis and field visibility. When comparing to scalpel, electrocautery or high frequency devices, lasers offer maximum postoperative patient comfort.
Methods: Ten patients agreed to undergo surgical removal of oral lesions of 808 nm diode lasers, power of 2 watt were used in continuous wave mode for excisional and incisional biopsies. The specimens were sent for histopathological examination and patients were assessed on intraoperative and postoperative complications.
Results: The obtained results showed that diode laser surgery was rapid, bloodless and well accepted by patients and led to complete resolution of the lesions. The excised specimen proved adequate for histopathological examination. Hemostasis was achieved immediately after the procedure with minimal postoperative problems, discomfort and scarring.
Conclusion: We conclude that diode lasers are rapidly becoming the standard of care in contemporary dental practice and can be employed in procedures requiring excisional biopsy of oral soft tissue lesions with minimal problems in histopathological diagnosis and minimal patient discomfort.
