The Autoclave Log, Cold Sterile Tray, and a Needlestick
A dental hygienist joins a small practice in Lewiston. On her first Monday, she finds that the autoclave log has no biological spore test entry for six weeks; the last chemical indicator strip is dated five weeks ago. Cured instruments are removed from the autoclave and placed in a tray, but heat-sensitive items and some prophylaxis angles are soaked in a glutaraldehyde “cold sterile” solution, rinsed, and used. Handpieces are wiped with alcohol between patients. The office has no written infection-control manual. The dentist tells her to “just get through the 14 patients; we’ll fix the log later.” During the first appointment, she sustains a needlestick while recapping an anesthetic needle after using it on a patient whose HIV status is unknown.
1. Identify the infection-control deficiencies and what the hygienist should do before continuing with patient care.

Several deficiencies fall below the Board’s infection-control rule, which incorporates current CDC and OSHA standards. Critical items-instruments that penetrate tissue-must be sterile. Soaking heat-sensitive items in glutaraldehyde is high-level disinfection, not sterilization, and is not acceptable for critical instruments. Handpieces are semi-critical or critical devices and must be cleaned and heat-sterilized between patients, not wiped with alcohol. The autoclave must be monitored mechanically, chemically with each load, and biologically with spore testing at the interval required by current guidance-weekly is the usual standard-and the results must be logged. A six-week gap means the practice cannot demonstrate that sterilization is working.
The hygienist should not use instruments of unknown sterility or improperly processed handpieces. She should notify the dentist immediately, stop the affected procedures, and help establish a compliant process before seeing more patients. If the dentist refuses to correct the conditions, she should decline to provide care in that setting and report the ongoing risk to the Board. A written infection-control manual and staff training also need to be in place.
2. What is the correct immediate management of the needlestick?
Read the worked answer
The needlestick is a bloodborne-pathogen exposure and must be handled immediately, not at the end of the day. She should wash the wound with soap and water, flush mucous membranes if involved, and report the exposure to the employer right away so the written exposure-control plan is activated. She needs prompt medical evaluation, including baseline testing and consideration of post-exposure prophylaxis for HIV and follow-up for hepatitis B and C according to current public health guidance. The source patient should be approached for testing only through the proper confidential process; the hygienist should not attempt to learn the patient’s status informally.
The exposure must be documented in the OSHA sharps injury log and the practice’s exposure report, without identifying the patient unnecessarily in the log. Recapping with two hands is prohibited; the incident should trigger a review of safe sharps practices, including use of a one-handed scoop or a safety device. The patient’s confidentiality must be protected throughout. If the practice has no exposure-control plan or refuses to arrange evaluation, the hygienist should seek care independently and report the practice’s noncompliance.
3. What reporting and documentation obligations arise from these findings?
Read the worked answer
The hygienist should create a contemporaneous, factual record of what she observed: the missing spore tests, the expired chemical indicator, the cold-sterile use for critical items, the handpiece wiping, the absence of a manual, and the needlestick. She should report the exposure through the employer’s exposure-control system and keep her own copy of the medical evaluation and follow-up instructions. The employer must maintain the sharps injury log and OSHA records as required.
Reporting to the Maine Board depends on the response. If the dentist corrects the sterilization and exposure-control failures promptly, internal remediation and documentation may be sufficient. If the practice continues to use improperly processed instruments or retaliates against her for raising the issue, she should report the ongoing infection-control violations to the Board. She should also consider whether the needlestick resulted from a prohibited practice-recapping-that the employer must correct. Her duty to patients includes refusing to participate in unsafe care; her duty to herself includes protecting confidentiality and obtaining timely medical follow-up.
