The White Plaque on the Tongue
During a routine prophylaxis in Norfolk, hygienist Elena notices a 1.5 cm white, non-scrapable plaque on the left lateral border of a patient’s tongue. The patient says it has been present for three weeks and is not painful. The patient smokes one pack per day and drinks alcohol socially. The patient asks, “Is that cancer? Should I worry?” Elena has taken continuing education in oral pathology but is not a dentist. The supervising dentist is in the building finishing a root canal and will be available in about 30 minutes. Elena wants to reassure the patient, finish the cleaning, and tell the patient to “watch it.” The patient is anxious and asks Elena to “just tell me it’s nothing.”
1. May Elena tell the patient the lesion is “nothing” or “not cancer”? Why or why not?
Read the worked answer
No. Elena may recognize that the lesion needs evaluation, but she may not give a definitive diagnosis or rule out cancer. Nebraska’s practice-of-dentistry definition and the dental hygiene regulations reserve diagnosis and treatment planning to the dentist. A dental hygienist’s scope includes data collection, patient education, and referral, not definitive oral pathology diagnosis.
Telling an anxious patient “it’s nothing” would be false reassurance and could delay care. The lesion’s duration, location, non-scrapable appearance, and the patient’s tobacco and alcohol use are red flags that require dentist evaluation. Elena should say something like, “I can’t diagnose this. It needs to be looked at by the dentist today because it has been there for three weeks.” She should not speculate about cancer or benign conditions.
2. What findings should Elena document, and how should she arrange follow-up?
Read the worked answer
Elena should document the lesion’s location, size, color, texture, duration, and whether it is scrapable or painful; the patient’s tobacco and alcohol use; the patient’s question and Elena’s response; and the referral to the dentist. She should avoid diagnostic labels such as “leukoplakia” unless the dentist uses them. A neutral entry is safer: “1.5 cm white, non-scrapable plaque, left lateral tongue, present three weeks; dentist evaluation requested.”
Elena should arrange for the dentist to examine the area before the patient leaves, if possible, or schedule the earliest available examination. If the dentist cannot see the patient, Elena should follow the office’s referral policy and document that the patient was advised not to wait. She should not simply tell the patient to “watch it.” A patient who refuses evaluation should have that refusal documented, along with the advice given.
3. If the dentist examines the lesion and says “come back in six months,” what should Elena do if the patient asks her whether that is safe?
Read the worked answer
Elena should not override the dentist’s clinical judgment, but she can explain the importance of follow-up and encourage the patient to ask the dentist directly about the reasons for the six-month interval. If the patient is worried or the lesion changes, Elena should facilitate another appointment rather than reassure the patient that nothing is wrong.
Elena may say, “The dentist has recommended rechecking it in six months. If it grows, bleeds, hurts, or you are worried before then, call us.” She should document the dentist’s recommendation, the patient’s questions, and any advice to return sooner. If Elena believes the interval is inconsistent with the office’s protocol, she should raise that with the dentist privately rather than undermine the dentist in front of the patient.
