ORAL HYGIENE REINFORCEMENTS IN

PURPOSE OF STUDY

PURPOSE

• Oral hygiene reinforcement
• Periodontal treatment
• Plaque control
• Ultrasonic debridement

VARIABLES

INDEPENDENT VARIABLE

- Oral hygiene reinforcement during 4 following visits after a 1 hour appointment with debridement and OHI

DEPENDENT VARIABLE

- Plaque and Bleeding

TYPE & STUDY OF DESIGN

DESIGN

• Parallel design
• Test group
• Control group

TEST GROUP

• 1 hr ultrasonic debridement
• OHI reinforcement at 4 appts
• 3 month recall
• OHI at weeks 2,4,8,9

CONTROL GROUP

• 1hr ultrasonic debridement
• OHI at 1st visit
• 3 month recall

SAMPLING STRATEGY

STUDY

• 6 month
• Perspective
• Controlled
• Parallel
• Randomized

TARGET GROUP

• 44 people
• Systemically healthy
• Chronic periodontitis
• Bone loss

SUBJECT EXCLUSIONS

• Less than 18 teeth
• Any systemic diseases
• SRP finished within the last 12 months

METHODS

METHODS

• BOP
• PI
• PPD
• CAL

TYPES OF CALIBRATION

EXAMINER

• 1 examiner
• Calibrated on 3 subjects
• 0.08-0.24 mm for PP
• -0.26-0.28 for CAL
• Blind study

INSTRUMENT CALIBRATION

• Hu-Friedy XP-23/QW
• 6 sites per tooth
• Parallel to the long axis

OUTCOMES MEASURED

3 MONTH RESULTS

• Reduction in bacteria
• Reduction in plaque
• Reduction in bleeding
• ONLY in TEST GROUP
• Disappeared at 6 mo.

POST 3 MONTH

• Test group had PPD reduction

RESULTS

Untitled Slide

RESULTS

• No significant difference
• Significant improvement

CONTROL GROUP

• Improvements in PPD
• Lower PI & BOP
• Reduction in PI and BOP

TEST GROUP

• All around improvement
• Greater PPD Reduction

COMBINED RESULTS

• No difference between
• - 5-7 mm pockets

CLINICAL SIGNIFICANCE

SIGNIFICANCE

Continuous OHI can help to form habits that that may be detrimental to oral health

AUTHORS INTERPRETATIONS

AUTHORS INTERPRETATIONS
- Lack of OH reinforcement. resulted in higher plaque and bleeding scores and accumulation of bacteria

AUTHORS INTERPRETATIONS CONT.
-Professional removal of dental biofilm every 3 months is beneficial in subjects with compromised plaque control

TREATMENTS

INCONSISTENCIES

• Baseline measured
• Same measurments taken at 3 & 6 mo.
• Both had 1 hr debridement
• Both had 3 month interval
• Teeth polished

BIAS

• Calibration on 1 examiner

VALIDITY

• OHI was consistent
• 1 Examiner screened and checked

OUR INTERPRETATIONS

OUR THOUGHTS

• OHI is important
• Do not want to overwhelm patients
• Excessive OHI May become disregarded
• Increased PI In test group

QUESTIONS ??

QUESTION 1
What experimental research group was used in this study?
A. Laboratory clinical trial
B. Cohort study
C. Randomized controlled
D. Animal research

Answer 1
C. Randomized controlled clinical trial- this specific type of scientific research tests a hypothesis and is used to test efficacy of specific interventions within a population where 1 group receives an Intervention (test group) and the other (control) does not

Question 2. What type of reliability is used when one examiner is calibrated
A. Inter-examiner
B. Intra-examiner
C. Co-examiner
D. Uni-examiner

Answer 2
B. Intra examiner- this is the type of calibration used with 1 examiner

Question 3 Which of the following is measured in the study
A. PI & BOP
B. BOP & PPD
C. CAL & PI
D. None of the above
E. All of the above

ANSWER 3

• All of the above

Question 4 What was the intervention used in this study?
A. OHI at 4 consecutive appts
B. Full mouth debridement
C. Delivery of antimicrobials
D. Use of antiseptic mouth rinse

Answer 4
A. Oral hygiene reinforcement in 4 consecutive appts- this study of clinical and microbiological outcome of a 1 hour ultrasonic debridement of CPP with and without sessions of OHI reinforcement.

Question 5. What interventions were used on both groups to keep consistency
A. Screening with an x ray
B. 1 hour ultrasonic debridement
C. Use of local anesthesia
D. All of the above

Answer 5
A&B- these were all used as interventions to keep the clinical trial consistent in both groups

Question 6. What criteria excluded a patient from the study
A. Less than 18 teeth
B. History of systemic disease
C. Chronic perio
D. A&B
E. None of the above

ANSWER 6

• A & B

Question 7 How many consecutive OHI reinforcement appts. Did the test group receive
A. 2
B. 4
C. 6
D. 8

Answer 7
B- 4 besides the initial and the 3 month OHI the test group received the 4 additional OHI appts

Question 8 Which of the following study methods reduces the bias in an experimental or evidence based study
A. Random sampling
B. Convienence Sampling
C. Judgmental sampling
D. Systematic sampling

Answer 8
A. Random sampling - this sampling allows everyone and anyone to have an opportunity to be included
