Influence of Environmental Factors on the Efficacy of Non-surgical Periodontal Treatment. A Pre-post Quasi-experimental Study
February 23, 2021 updated by: Nicola Discepoli, University of Siena
Periodontitis is a biofilm-mediated chronic inflammatory disease which causes the destruction of the supporting tissues of the tooth.
Risk factors for periodontitis include familiarity for periodontal diseases, diabetes, cardiovascular diseases, metabolic syndrome, obesity and stress.
Some studies demonstrated how these risk factors negatively influence the patients' response to non-surgical periodontal treatment.
The success of non-surgical periodontal therapy is defined through the treat-to-target concept (i.e. a maximum of 4 sites with Probing Pocket Depth >5mm and presence of Bleeding on Probing); therefore, periodontal treatment is successful whenever this threshold is reached.
Moreover, given the available data regarding the association between more severe forms of periodontitis and a lower frequency of physical activity, a worse sleep quality and more perceived stress, it is reasonable to hypothesize that these factors could influence the patients' response to non-surgical periodontal treatment.
With regards to diet, despite many studies appraised the anti-inflammatory effect of the mediterranean diet, no study has ever related adherence to Mediterranean Diet to oral health status.
The novelty that the present study would introduce is the evaluation of how environmental factors (i.e.
diet, physical exercise, perceived stress) influence patients' response to non-surgical periodontal therapy.

---|---|
patients affected by untreated Periodontitis
patients coming to the Unit of Periodontics at the University of Siena will be screened for the inclusion in the study.
All patients eligible for the inclusion in the study will undergo non-surgical periodontal treatment and will be administered a questionnaire about lifestyles (adherence to mediterranean diet, sleep quality, physical activity, perceived stress).
Patients will be then reevaluated at 3 months after the completion on non-surgical periodontal therapy.
|
all included patients will be subjected to non-surgical periodontal therapy
All patients will be asked to complete a set of questionnaires regarding:

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Treat-to-target after treatment (yes/no)
Time Frame: outcome measured at reevaluation (3 months after the completion of non-surgical periodontal treatment)
|
Binary outcome defining the success of non-surgical periodontal treatment.
The treat-to-target is reached whenever patients at reevaluation have a maximum of 4 sites with Probing Pocket Depth (PPD) >5mm and presence of Bleeding on Probing (BoP)
|
outcome measured at reevaluation (3 months after the completion of non-surgical periodontal treatment)

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Influence of adherence to Mediterranean diet on the success of non-surgical periodontal treatment (treat-to-target)
Time Frame: outcome measured at reevaluation (3 months after the completion of non-surgical periodontal treatment)
|
results obtained from the questionnaire about adherence to Mediterranean Diet (Gnagnarella et al. 2018) will be placed in a logistic regression model, whose aim will be to investigate the influence of adherence to Mediterranean diet (predictors) on the success of non surgical periodontal treatment (treat to target; dependent variable).
Adherence to Mediterranean diet is evaluated on a scale between 0 and 9; the higher the score, the higher the adherence to Mediterranean Diet.
|
outcome measured at reevaluation (3 months after the completion of non-surgical periodontal treatment)
|
Influence of Sleep Quality on the success of non-surgical periodontal treatment (treat-to-target)
Time Frame: outcome measured at reevaluation (3 months after the completion of non-surgical periodontal treatment)
|
results obtained from the questionnaire about Sleep Quality (Pittsburgh Sleep Quality Index) will be placed in a logistic regression model, whose aim will be to investigate the influence of sleep quality (predictor) on the success of non surgical periodontal treatment (treat to target; dependent variable).
Sleep quality is evaluated on a scale between 0 and 21; the higher the score, the poorer the Sleep Quality.
|
outcome measured at reevaluation (3 months after the completion of non-surgical periodontal treatment)
|
Influence of Physical Activity on the success of non-surgical periodontal treatment (treat-to-target)
Time Frame: outcome measured at reevaluation (3 months after the completion of non-surgical periodontal treatment)
|
results obtained from the questionnaire about Physical Activity (International Physical Activity Questionnaire) will be placed in a logistic regression model, whose aim will be to investigate the influence of amount of Physical activity (predictor) on the success of non surgical periodontal treatment (treat to target; dependent variable).
Physical activity is evaluated on a scale between 0 and 2 (0= low physical activity; 1= moderate physical activity; 2= intense physical activity).
|
outcome measured at reevaluation (3 months after the completion of non-surgical periodontal treatment)
|
Influence of Perceived Stress on the success of non-surgical periodontal treatment (treat-to-target)
Time Frame: outcome measured at reevaluation (3 months after the completion of non-surgical periodontal treatment)
|
results obtained from the questionnaire about Perceived stress (Italian Perceived Stress Scale) will be placed in a logistic regression model, whose aim will be to investigate the influence of perceived stress (predictor) on the success of non surgical periodontal treatment (treat to target; dependent variable).
Perceived Stress is evaluated on a scale between 0 and 40; the higher the score, the higher the stress perceived.
