ABSTRACT
Objective: The Aim Of The Current Study Was To Evaluate The Effect Of Antioxidants (Vitamin C, E And Zinc) Clinically And Radiographically On The Investing Tooth Structure Of Patients With Chronic Periodontitis.

Materials and Methods: This Study Was Conducted�on 20 Patients, Suffering From Chronic Periodontitis, Divided Into 2 Groups 10 Patients Receive Vitamin C, E And Zinc (test Group), 10 Patient Didn?t Receive Vitamin C, E And Zinc (control Group). Clinical Recordings (GI And CAL) Were Scored For Each Participant In The Study Before And After Non- Surgical Periodontal Treatment.�GCF Samples Were Obtained From Each Patient Included In The Present Study And The Amount Of MPP-8 In The GCF Samples Was Determined Using PCR. Radiographic Assessment For Bone Height Done By Digital Panoramic Radiographs. All Participant Were Followed Up At 1 Month And 3 Months.

Results: The GCF Concentration Of MPP-8 Was Significant Difference On ?mean % Of Change In MMP-8 Between Control Group And Test Group After 1 Month, 3 Months With P=0.023 And P=0.004 Respectively. Regarding To Radiographic Assessment Of Bone Height, It Showed A Significant Increase In Mean ? Bone Height In Control Group After 1 Month And After 3 Months With P=0.002 And P�0.001 Respectively. And Also There Was A Significant Increase In Mean ? Bone Height In Test Group After 1 Month And After 3 Months At P=0.004 And P�0.001 Respectively.

Conclusions: Radiographs Plays Integral Role In The Assessment Of Periodontal Diseases. They Provide Information About The Status Of Periodontium That Cannot Be Obtained Clinically. They Are Helpful In Evaluation Of Amount Of Bone, Present Condition Of Alveolar Crest, Bone Loss In The Furcation Area, Width Of The PDL, Local Irritating Factors And Poorly Contoured Restorations.
