Brief Summary

ozone therapy has been extensively used in dentistry to manage wounds healing, dental caries, oral lichen planus, gingivitis and periodontitis, halitosis, osteonecrosis of the jaw, post-surgical pain, plaque and biofilms, root canal treatment, dentin hypersensitivity, tempro-mandibular joint disorders and teeth whitening, And based on the above, in this study kiwi extract and ozone gas will be used individually and combined to evaluate the resultant effects on bleaching, enamel microhardness and micromorphology.

Conditions

Discoloration, Tooth

Outcome Measures

Primary Outcomes (4)

• Color change assessment

  all participants will be requested to return after 24 hours to permit rehydration of tooth surfaces before shade assessment Tooth Shades will then record using colorimeter. The color change (ΔE) will be calculated using the formula: ΔE= {(ΔL) 2+ (Δa) 2+ (Δb)

  24 Hours

• Color change assessment

  all participants will be requested to return after one month for tooth shades recording using colorimeter. The color change (ΔE) will be calculated using the formula: ΔE= {(ΔL) 2+ (Δa) 2+ (Δb) at one month

  one month

• Color change assessment

  all participants will be requested to return after one month for tooth shades recording using colorimeter. The color change (ΔE) will be calculated using the formula: ΔE= {(ΔL) 2+ (Δa) 2+ (Δb) at three months

  three month

• Color change assessment

  all participants will be requested to return after one month for tooth shades recording using colorimeter. The color change (ΔE) will be calculated using the formula: ΔE= {(ΔL) 2+ (Δa) 2+ (Δb) at six months

  six months

Study Arms (4)

bleaching with 2% kiwi extract.

EXPERIMENTAL

The fresh pulpy kiwi will be bought 200 gm of kiwi fruits were cleaned, cut into round shapes and blended with 15 mL of distilled water in a blender to obtain about 50 mL of kiwi concentrate. This concentrate will be filtered and then transferred into a cooling centrifuge to be processed at 2000 rpm for about 20 minutes at a temperature of 40°C. The extract thus collected will be stored at 4°C till further use.

Device: Bleaching

bleaching using 2,350 ppm ozone gas.

EXPERIMENTAL

A 2,350 ppm ozone concentration at a 615 cc per minute flow rate will be supplied by a well-known ozone producing machine. The ppm of ozone supplied will be verified via an ozone detection device, and the ozone flow rate will be verified by a flow meter directly before the start of the experiment. Ozone gas will be distributed to the tooth surfaces through special trays to assure a perfect seal to prevent any ozone leakage and to be safely employed to humans

Device: Bleaching

bleaching with 2% kiwi extract followed By 2,350 ppm ozone gas.

Device: Bleaching

bleaching with 38% hydrogen peroxide.

EXPERIMENTAL

Application of 38% H2O2 gel for 20 minutes. Then, the H2O2 gel will be removed, and teeth will be sprayed for 10 seconds with water from a 3-in-1 syringe

Device: Bleaching
