Dental Epidemiology Survey (5 year olds) privacy notice for parents and carers

We keep this privacy notice under regular review and it was last updated in March 2022.

This notice explains what personal data (information) we hold about you and how we collect, use and may share information about you. We are required to give you this information under data protection law.

Who we are

Kent County Council (KCC) collects, uses and is responsible for certain personal information about you. When we do so we are regulated under the United Kingdom General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018 (DPA 2018). We are responsible as ‘controller’ of that personal information. Our Data Protection Officer is Benjamin Watts, whose contact details are set out at the bottom of this privacy notice.

The Dental Epidemiology Survey is delivered by Kent Community Health Foundation Trust (KCHFT), on behalf of KCC, every 2 years. This survey enables us to collect information on the health of people’s teeth and mouths (their oral health), so that we can plan and improve local dental services. This year the survey will be collecting information about the oral health of 5 year old children across Thanet, Gravesham, Dartford and Swale. Parents and carers who have a child aged 5 in participating schools in these districts will be asked if they give permission (called a ‘common law consent’) for their child to take part in the survey and have a brief dental check (examination) at their school, to take place during Terms 4 to 6 (April to July 2022).

The personal information we collect and use

Information collected by us

If you give permission to your child taking part in the survey and having a dental check, we will collect the following personal information when you provide it to us:

  • Your child’s personal details, including their name, address (including postcode), date of birth, sex, school name and district and school class.
  • Your full name (as the child’s parent or carer) and, if you choose to provide it, your contact telephone number so that we can contact you to offer advice if there are any concerns about your child’s teeth or mouth.

We also collect the following ‘special category data’ (personal data which is more sensitive and is treated with extra care and protection) when you provide it to us:

  • Information about your child’s racial or ethnic origin
  • Information relating to your child’s oral health (e.g. the number of decayed, filled, or missing teeth that they may have).

How we use your personal information

We use your personal information for the following purposes:

  • To plan, organise and deliver the survey, and make sure we only carry out a dental check on children who are aged 5 at the time of the survey.
  • So that we can contact you to offer advice and support if we find any concerns about your child’s teeth or mouth during the dental check.
  • To better understand children’s oral health across Thanet, Gravesham, Dartford and Swale, and how this may have changed over the last 2 years.
  • To plan and improve how we can best support children and families to care for their mouths and teeth.

Reasons we can collect and use your personal information

When we collect your personal data, we rely on the following legal bases:

  • Article 6(1)(c) - processing is necessary for compliance with a legal obligation to which the controller is subject.
  • Article 6(1)(e) - processing is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller.

When we collect your ‘special categories of personal data’, (such as health, race, ethnicity) we rely on the following legal bases:

  • Article (9)(2)(h) - processing is necessary for the provision of health or social care or treatment or the management of health or social care systems and services.

We rely on the health or social care purpose and public health conditions from Schedule 1 of the Data Protection Act 2018 when relying on Article(9)(2)(h) to process your special category data.

We take the following appropriate safeguards in respect of your special category and/or criminal convictions data when relying on the conditions above:

  • We have a retention schedule which explains how long data is retained
  • We maintain a record of our processing in our ‘Record of Processing Activities’ and record in it any reasons for deviating from the periods in our Retention Schedule.

How long your personal data will be kept

In line with the NHS Records Management Code of Practice, we will hold and use your child’s personal information until their 25th birthday, after which the information is made inaccessible to system users or securely destroyed. Any paper copies will be securely destroyed after 1 year.

We will hold your telephone number, when you provide it to us, for 1 year after which time this information will be securely destroyed.

Who we share your personal information with

In the course of working with you, we may collect information from, or share it, with some of the following third parties (non exhaustive list):

  • Kent Community Health Foundation Trust (KCHFT) will be conducting the Dental Epidemiology Survey on KCC’s behalf. KCHFT will remove as much as possible of the identifiable information that you provide.

We will also share a limited, de-identified data set with Kent Public Health Observatory (part of KCC) who will be analysing the survey results.

We will share personal information with law enforcement or other authorities if required by applicable law or in connection with legal proceedings.

We will share personal information with our legal and professional advisers in the event of a dispute, complaint or claim. We rely on Article 9(2)(f) where the processing of special category data is necessary for the establishment, exercise or defence of legal claims or whenever courts are acting in their judicial capacity.

Transferring your information outside of the UK

KCHFT uses Wordpress as part of processing your personal data which is hosted using Microsoft Azure cloud services, within the EU. This means that we will transfer your data outside of the UK to the EU for processing.
