We are currently seeking participants for a new research study regarding the relationship between ‘Diabetes and Periodontal disease’.

You are eligible to participate in the study if you are:

• Aged 18 or over;
• Your diabetes was diagnosed at least six months ago and;
• You have at least 10 teeth remaining in your mouth

About the study

The research program is being conducted by Dr Allauddin Siddiqi and Professor Alexandro Quaranta from Griffith University’s School of Dentistry and Oral Health.

Many people with diabetes or periodontal disease are unaware of their conditions and don’t understand the impacts they can have on the severity of their conditions. The growing number of diabetic patients around the world pose an urgent need to educate health professionals and diabetic patients about the impact of periodontal health on diabetes and vice versa. An active collaboration between medical and dental professionals is the key for integrated approach to diabetic patient care.

This research is designed to evaluate the knowledge and attitude of diabetic patients towards oral health and its systemic effects. The research will aim to minimize the burden of disease (diabetes) in the health sector by reducing/controlling the glycaemic level of diabetic patients through educating them about the relationship between oral and systemic health and vice versa.

Participant information sheet

Research title: Awareness of bidirectional relationship between “Diabetes and Periodontal disease” among medical professionals and diabetic patients: An overlooked connection 

Researchers: Dr Allauddin Siddiqi, BDS, PDD, MSc, PhD (School of Dentistry and Oral Health, Griffith University), Alex Quaranta (Discipline lead, Periodontics, School of Dentistry and Oral Health, Griffith University), and Professor Boyen Huang (Head, School of Dentistry, CSU).


Before you decide whether or not you wish to participate in this study, it is important for you to understand why the research is being done and what it will involve. Please take the time to read the following information carefully and discuss it with others if you wish.

  1. What is the purpose of this study?

Many people living with diabetes or periodontal/gum disease are unaware of their oral and dental conditions. Similarly, they are ignorant of the fact that these two conditions have a direct relationship in terms of the severity of the disease. This research is aimed at investigating the knowledge and attitude of both medical professionals/diabetic educators and people living with diabetes towards the oral health of diabetic patients. The current research will develop educational strategies aimed at prevention and early management of periodontal/gum disease in people living with diabetes that will improve the quality of life of these individuals.

  1. Why have I been invited to participate in this study?

You have been invited to this study because you are registered with Diabetes NSW or you contacted us and self-identified as a person living with diabetes. You are eligible to participate in the study if your diabetes was diagnosed at least six months ago, you have more than ten remaining teeth and you are over 18 years old.

  1. What does this study involve?

There are two parts to this study. You may participate in either one or in both.

Part 1: The first part of study involves an online survey, which should take you around 10-15 minutes to complete. The link to the survey is at the end of this information sheet. To participate in this part of the study, after reading the remaining information on this form, you just need to follow the link and complete the survey. Alternatively, you can request a paper copy of the survey from the reception desk at the clinic. Submission of the completed survey will indicate your consent to participate in this part of the study.

Part 2:  The second part of the study involves a free dental examination/consultation and oral hygiene education session at the School of Dentistry and Oral Health, Griffith University. This examination will provide the researchers with further information on the relationships between periodontal disease

and diabetes. If you participate in this part of the study, you will be examined by the chief researcher Dr Allauddin Siddiqi at one of the dental clinics affiliated with GU, and appropriate instructions and referrals will be made if a need for further treatment is identified. The examination should take no more than 15 minutes. Every participant attending for an examination will be given an oral hygiene pack (a tooth paste, a tooth brush, and a mouth rinse) at the end of the appointment.

If you decide to participate in this part of the study after reading this information you will need to complete a Consent Form and return it as per the instructions on the form. You will then be contacted by the researcher or the receptionist at the dental clinic to make an appointment for your examination.

  1. Are there risks and benefits to me in taking part in this study?

No risks are anticipated for participants in this. However, should you feel any distress or concern following completion of the survey, please contact your GP, diabetes educator or the researcher for support.

You may personally benefit from participation by way of increased awareness of the links between diabetes management and oral health care.

  1. How is this study being paid for?

This study has minimal costs. Colgate Palmolive have donated the oral hygiene products provided to all participants attending for an examination. The same company has alsodonated one year’s supply of oral hygiene products, for which all participants can go into a draw.

  1. Will taking part in this study (or travelling to) cost me anything, and will I be paid?

No, being involved does not cost you anything, except for any expenses you may incur travelling for the examination.

  1. What if I don’t want to take part in this study?

Participation in this research is entirely on a voluntary basis. If you do not want to participate in this research, you are under no obligation to do so. Whether or not you decide to participate, is your decision and will not disadvantage you. In particular, a decision not to participate will have no impact on you attending Oral health centre, Griffith University or any of its clinics in the future.

  1. What if I participate and want to withdraw later?

The survey will not collect any identifying information. It will therefore not be possible to withdraw your survey if you choose to withdraw from the study after you have submitted the survey.

If you decide to withdraw from participation prior to submission of the survey, simply close your browser window. This will result in an incomplete survey being submitted, however all such surveys will be destroyed by the researchers and not included in the final data set.

  1. How will my confidentiality be protected?

The data will be kept in a password projected folder accessible only to the investigators and will be stored with the researcher on password protected computer devices. All relevant files will be deleted after 5 years.

  1. What will happen to the information that I give you?

Data will be analysed and reports produced for publication in peer reviewed journals. The reports will focus on establishing guidelines for our medical professionals when they treat diabetic patients and to educate them regarding the bidirectional relationship between diabetes and periodontitis. This will then enable them to better educate people living with diabetes about maximising their oral health.

  1. What should I do if I want to discuss this study further before I decide?

If you would like further information please contact either of the researchers via the email at the top of this document.

  1. Who should I contact if I have concerns about the conduct of this study?
