Before dental treatment, a clinic should record the patient’s allergies, every current medicine (especially blood thinners and bone medicines), conditions such as diabetes, high blood pressure and heart disease, pregnancy or breastfeeding, and recent lab values with their dates. Confirm it again at the start of each new course of treatment, and keep it where the dentist sees it before treating — not in a file nobody opens.
This is a documentation and safety checklist for the clinic, not clinical guidance. What any answer means for treatment is the dentist’s decision, together with the patient’s physician where needed.
Why does a dental clinic need a written medical history?
Dentistry involves local anaesthetic, procedures that can bleed, and medicines that interact with what patients already take. A written history does three jobs:
- It informs the dentist before an injection, an extraction or a prescription.
- It informs everyone else — the associate who sees the patient next month, the assistant preparing the tray, the front desk booking a long procedure.
- It records that the question was asked. If something goes wrong, a dated, signed history shows what the clinic knew and when.
The checklist: what to ask and what to record
| Item | What to record | Why the clinic needs it written |
|---|---|---|
| Allergies | Medicines, local anaesthetic, latex and anything else, with the reaction and when it happened; or “no known allergies” with the date | Checked before every injection and prescription |
| Current medicines | Name, strength and how often, including over-the-counter, ayurvedic and homeopathic products and supplements | The dentist checks interactions before prescribing |
| Blood thinners | The medicine, who prescribed it and why, and any recent report (such as INR) with its date | Planning procedures that can bleed |
| Diabetes | Type, medicines or insulin, and the latest sugar or HbA1c report with its date | Planning appointments, surgery and healing |
| Blood pressure | Known high blood pressure and its medicines; any reading taken in the clinic, with date and time | Planning long or stressful procedures |
| Heart conditions | Past heart attack, stents, valve problems, pacemaker, heart surgery; the cardiologist’s name | The dentist may need to consult the physician |
| Bone medicines | Bisphosphonates or other bone medicines: name, tablet or injection, how long, and the reason | Relevant when planning extractions and implants |
| Pregnancy and breastfeeding | Status and, for pregnancy, the number of weeks; the obstetrician’s name | X-rays, medicines and timing of treatment |
| Other conditions | Asthma, epilepsy, thyroid, kidney or liver disease, bleeding disorders, anaemia, hepatitis B or C, HIV, TB, joint replacement, organ transplant, cancer treatment (especially radiotherapy to the head and neck, or chemotherapy) | Each can change how and when treatment is done |
| Past dental experiences | Fainting, a reaction to anaesthetic, heavy bleeding after an extraction, severe anxiety | Helps the team prepare for the next visit |
| Habits | Smoking, gutkha, khaini, paan or areca nut, alcohol | Relevant to healing and to oral health generally |
| Contacts | The family physician and an emergency contact, with phone numbers | Someone to call when the dentist has a question |
Ask about steroids and medicines for mental health, too: they belong in the medicine list like everything else, and patients may leave them out unless asked.
How should the questions be worded?
Patients answer the question they understand, not the one you meant. Use plain words in the patient’s language, and ask about the things patients do not think of as “medicine”:
- Not “Are you on anticoagulants?” but “Do you take any medicine to thin the blood — for example after a heart problem, a stroke or a stent?”
- Not “Any osteoporosis therapy?” but “Do you take any tablet or injection for weak bones?”
- Not “Medical conditions?” but “Do you have sugar, BP, thyroid or any heart problem?” — the words many patients in India use themselves.
- Add “Are you taking any ayurvedic, homeopathic or home medicine?” — these are often missed.
- Ask every woman for whom it could apply, privately, “Are you pregnant, or could you be, or are you breastfeeding?” — at every new course of treatment, not just the first visit.
Keep the form in the languages your patients read, for example English, Hindi and Gujarati. For patients who cannot read, a staff member reads each question aloud and notes that they did.
How should lab reports be recorded?
Patients often bring reports for sugar, HbA1c, INR, platelets or haemoglobin. Record them so they can be trusted later:
- The test name, exactly as on the report.
- The value and the unit — a number without its unit is meaningless.
- The report date — an old value is not a current value.
- The lab’s name and the reference range it prints.
- The report itself, scanned or photographed into the record.
Keep earlier values rather than overwriting them, so the dentist can see the trend. Make sure the name on the report is the patient’s. What a value means for treatment is the dentist’s call, not the front desk’s.
When should the medical history be re-confirmed?
- At the start of every new course of treatment. A patient back after a year may have started new medicines.
- At each visit, briefly: “Any change in your health or medicines since last time?” Record the answer, even when it is “no change”.
- Before procedures that can bleed, such as extractions, implants and gum surgery.
- Before prescribing. The prescription is only as safe as the medicine list; see what a dental prescription in India should contain.
- After a hospital stay or a new diagnosis, whenever the patient mentions one.
Every re-confirmation should leave a trace: the date, the person who checked, and what changed.
How do you make sure it is seen before treatment?
The most complete history is useless if nobody looks at it. Build the check into the visit itself:
- Put alerts where the dentist looks. On paper, a coloured sticker on the file cover for allergies and blood thinners. In software, a banner on the patient’s record.
- Read it back to the patient before work starts: “You told us you are allergic to … and you take … — is that still right?”
- Check it again when prescribing, against the allergy and medicine list.
- Link it to consent. Confirming the history is part of taking consent for a procedure; see what a dental consent form should include.
Who fills in the history, and who signs it?
A workable pattern for a busy clinic: the patient fills in the form (on paper, a tablet or their phone) before the first visit; the front desk checks that no question is left blank; the dentist reviews it, asks follow-up questions, and signs and dates it. If a family member answers for the patient, note who gave the information.
When you move from paper files to software, bring the medical history across first, before old treatment notes. Our guide to moving from paper records to dental software covers the rest.
Keeping it private
A medical history is personal health information. Only the people who need it should see it, it should not be discussed across the waiting room, and it should not travel through staff members’ personal phones. India’s Digital Personal Data Protection Act, 2023 applies to it like any other personal data the clinic holds.
How Odontra helps
In Odontra, allergy and medical alerts show on the patient’s record before you treat and are checked again when you prescribe. In the visit guide, the doctor reads the allergies, conditions and medicines back to the patient and confirms them before work starts. With Odontra AI (Pro and Premium), a photo of a prescription or medicine strips becomes a medicine list with blood thinners, bone medicines, steroids, diabetes and BP medicines flagged, and a photo of a blood report puts values such as sugar, HbA1c, INR and platelets on the record with their dates, flagged high or low — the flag describes the number, and the dentist decides what it means. Nothing is saved until a person ticks it. Patients can also photograph their own prescription while registering in the patient app.
