Bleaching Effect of Solo and Combined Kiwi Extract and Ozone and Their Impact on Enamel

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: bleaching with 2% kiwi extract.; 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
Experimental: bleaching using 2,350 ppm ozone gas.; 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

Experimental: bleaching with 38% hydrogen peroxide.; 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; Bleaching

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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
