Every dental practice in Italy must have a written reprocessing protocol approved by the practice owner. The ASL can request it during announced and unannounced inspections. The 2010 ISPESL Linee Guida and UNI/TR 11408:2011 are the reference documents. The Legge Gelli (Art. 5 and Art. 6) makes documented adherence to published guidelines a condition of criminal non-punishability. This guide describes what the protocol must contain, how it must be structured, and how documented compliance becomes a legal protection in professional liability proceedings.
In Italy, every dental practice must have a written reprocessing protocol, approved by the practice owner (titolare dello studio, the legal employer under D.Lgs 81/2008) and accessible to all staff. This protocol is a formal document that describes every phase of reprocessing, the related controls, and the corrective actions in the event of non-conformity. D.Lgs 81/2008 Title X (Art. 274) establishes systematic reprocessing as an obligation for the healthcare facility, and the ISPESL Linee Guida of May 2010, together with UNI/TR 11408:2011, define the operational content of the protocol. The ASL (in Lombardia: ATS) may request it during planned or unannounced inspections.
This is not merely a poster on the wall — it is an operational document that describes how, when, and by whom each phase is performed. Its absence or insufficiency is a non-conformity frequently documented in inspection reports, and it is decisive in assessing non-punishability under Art. 590-sexies of the Criminal Code introduced by the Legge Gelli (Law 24/2017).
A complete reprocessing protocol for an Italian dental practice must include: a detailed description of every phase of the reprocessing chain (decontamination, washing, rinsing, drying, inspection, packaging, autoclave cycle, storage, traceability — per ISPESL Linee Guida 2010 and UNI/TR 11408); the products used at each phase (commercial name, concentration, contact time); the autoclave's sterilization parameters (program, temperature, pressure, duration, prion cycle 134°C/18 min); the autoclave class (UNI EN 13060 — Class B mandatory for hollow instruments); the frequency and type of controls (daily Bowie-Dick or Helix, Class 1 chemical indicators per UNI EN ISO 11140-1 on every load, biological spore indicators at intervals based on risk analysis); the procedure for a failed cycle or non-conform test; the autoclave maintenance plan (periodic servicing, annual performance qualification per UNI EN ISO 17665-1, calibrations, gasket replacement); identification of staff authorized to operate the autoclave; and the traceability procedure (what is recorded, how, where it is archived, retention period 5–10 years).
The protocol must be updated when a product, device, or procedure changes. Each update must be dated and signed by the responsible person. Staff training on the protocol must be documented.
Cycle validation consists of verifying that the recorded parameters (temperature, pressure, duration) match the parameters of the selected program. A cycle is conform when the autoclave report shows that the required values were reached and held for the required time — typically 134°C for 18 minutes for the prion cycle. UNI EN ISO 17665-1 defines the annual performance qualification (OQ) of the sterilization process.
Beyond physical parameters, validation includes: verifying that the day's Bowie-Dick or Helix test was conform; checking that chemical indicators changed color correctly; documenting the biological-indicator result, where required by the control plan; visually inspecting pouch integrity after the cycle (no moisture, intact seal). A non-conform cycle voids the entire load — instruments must be repackaged and resterilized.
Article 7 of the Legge Gelli establishes dual liability: the struttura sanitaria (healthcare facility) bears contractual liability (Civil Code Art. 1218, 10-year prescription) and the practitioner bears extracontractual liability (Art. 2043, 5-year prescription). This is the only context in which "struttura sanitaria" is the correct term — it is the exact wording of the law.
The combined effect of Art. 5 + Art. 6 of the Legge Gelli (with Art. 590-sexies of the Criminal Code) grants criminal non-punishability to the practitioner only when: (1) the published guidelines were followed; (2) adherence is documented. Without a written protocol and without records, non-punishability does not apply. The reprocessing protocol, cycle records, periodic controls, and digital archive together form the legal-defense element for the practice owner and staff.
In every Region, the ASL (Azienda Sanitaria Locale) — in Lombardia ATS (Agenzia di Tutela della Salute) — is the authority that inspects dental practices. Inspections may be planned (within the public-health service's inspection calendar) or unannounced (in response to a complaint or health alert). The inspector verifies: the existence of the written protocol, its adequacy against current rules, that staff know and apply it, that sterilization records are complete and up to date, and that the periodic controls (Bowie-Dick, biological) are performed as documented.
FNOMCeO and the Albo degli Odontoiatri at the provincial CAO may also receive and handle complaints regarding shortcomings in clinical practice, including sterilization. Registration is mandatory.
Every autoclave cycle must produce an individual record including: cycle start and end date and time, cycle number (sequential or generated by the autoclave), program used, parameters reached (maximum temperature, pressure, sterilization-phase duration), result (conform/non-conform), list of instruments included in the load, operator identification, and any observations ("reduced load", "cycle repeated after Bowie-Dick failure").
The autoclave's printed or digital report must be retained alongside the record, for the period required by the ISPESL Linee Guida and the regional directive (5–10 years). In a digital system like SecuSteri, the report is imported automatically, parameters are extracted, and the record is generated without manual intervention — eliminating transcription errors and ensuring availability within the 7 days required by Article 4 of the Legge Gelli.
