The proposed study will test the following hypotheses:

  1. Pre-operative daily dual supplementation with Juice Plus+ (fruit & vegetable) for 11 weeks will result in reduced post-operative morbidity in terms of quality of life, pain and trismus after 1 week following surgical removal of lower third molars, when compared to placebo.
  2. Pre-operative daily dual supplementation with Juice Plus+ (fruit & vegetable) for 11 weeks will reduce serum markers of oxidative stress, following surgical removal of lower third molars, when compared with placebo.

Condition Intervention
Postoperative Morbidity
Wound Healing
Dietary Supplement: Juice plus

Study Type: Interventional
Study Design: Allocation: Randomized

Official Title: Efficacy of Adjunctive Juice Plus in Reducing Post-operative Morbidity and Improving Quality of Life After Lower Third Molar Surgery: a Randomized Controlled Clinical Trial

Further study details as provided by University of Birmingham:

Primary Outcome Measures:
  • Quality of Life [ Time Frame: first postoperative week ]
    QOL as assessed by PoSSe scale (Ruta et al., 2000)

Secondary Outcome Measures:
  • trismus [ Time Frame: postoperative week ]
    trismus will be assessed by investigator at 48h and 1 week postoperative, and every postop day by patient

  • postoperative pain [ Time Frame: postoperative week ]

    pain will be assessed by patient on VAS on each postop day. groups will be compared for the following:

    • total (sum) of pain scores over 1 week
    • proportion of patients reporting >50% pain on day 2 and day 7
    • time until pain consistently <50%
    • proportion of patients reporting 20mm increase in pain after postoperative day 3

  • analgesic use [ Time Frame: first postoperative week ]
  • plasma total antioxidant capacity (TAOC) [ Time Frame: baseline (preop) and 1 week postop ]
    group differences between plasma TAOC changes between baseline and 1 week postop

  • serum biomarkers of oxidative stress [ Time Frame: first postoperative week (baseline and 1 week) ]
    differences in change from baseline to 1 week of mean protein carbonyls, isoprostanes and 8OHdG

  • serum concentration of acute phase reactants [ Time Frame: first postoperative week ]
    change between baseline and 1 week of: CRP, fibrinogen, WBC

  • adverse events [ Time Frame: first postoperative week ]

Enrollment: 246
Study Start Date: June 2010
Study Completion Date: April 2013
Primary Completion Date: April 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Juice Plus Dietary Supplement: Juice plus
Juice Plus (2 capsules bds) for 11 weeks (10 weeks preop and 1 week postop)
Placebo Comparator: Placebo Dietary Supplement: Juice plus
Juice Plus (2 capsules bds) for 11 weeks (10 weeks preop and 1 week postop)

Detailed Description:

In general antioxidant status appears to influence wound healing in humans and in animal models of acute trauma, with low antioxidant concentrations and excessive oxidative stress being associated with impaired healing. Whilst antioxidant supplementation has been reported to improve plasma antioxidant status and wound healing in animal models of acute trauma, there is remarkably little data from human studies.

The use of Juice Plus+ has been reported to increase serum concentrations of important antioxidants and reduce serum markers of oxidative stress. However, to date there are no reported studies concerning the potential for Juice Plus+ to improve patient-based outcome measures following the surgical removal of lower third molars. This study therefore proposes to investigate the impact of daily supplementation with Juice Plus+, in improving outcomes following surgical trauma. While the rationale for the proposed study is primarily predicated on the established role of oxidative stress and antioxidant micronutrients in chronic inflammatory diseases, the proposed randomized controlled clinical study represents an efficient way of evaluating the potential for adjunctive Juice Plus+ use in improving wound healing and reducing post-operative morbidity following surgical procedures on humans.
