Every dental practice in Spain must have a written sterilization protocol validated by the practice director. Regional health authority inspectors check for it during both planned and unannounced visits. This guide details what your protocol must contain and what inspectors look for.
In Spain, every dental practice must have a written sterilization protocol, accessible to all staff and available for presentation during inspections. This document describes the procedure to follow at each step of the sterilization chain and assigns responsibilities. Real Decreto 1594/1994 requires systematic sterilization, and the healthcare center registration requirements enforced by each autonomous community's Consejería de Sanidad (regional health authority) expect a documented protocol as part of the practice's quality management system. The protocol must be validated by the practice director (director del centro).
The designation of the person responsible for sterilization within the practice. A detailed description of each step in the sterilization chain (pre-disinfection, cleaning, rinsing, drying, packaging, autoclaving, storage). The maintenance and validation schedule for the autoclave (initial qualification, annual requalification, preventive maintenance). The frequency of biological and physico-chemical controls. The traceability method used (paper or digital register). The medical waste management procedures. The continuing education plan for staff.
For a step-by-step breakdown of the sterilization chain, see our dental sterilization chain guide.
A cycle is valid when the recorded parameters match the selected program and all indicators are compliant. In Spanish dental practice, the reference cycle is 134°C for 18 minutes (prion cycle), recommended for instruments in contact with nervous or lymphoid tissue. The autoclave must be Class B to sterilize hollow instruments (turbines, contra-angles) and wrapped loads, in accordance with UNE-EN 13060.
Before the first load of each working day, a Bowie-Dick test (pre-vacuum autoclaves) or Helix test (hollow instruments) validates proper autoclave function. A failed cycle or a non-compliant indicator requires repackaging and resterilization of the entire load.
For details on biological controls, see our autoclave biological controls guide.
The Consejería de Sanidad (regional health authority) of each autonomous community conducts inspections of dental practices as part of healthcare center oversight. While there is no single national evaluation grid equivalent to the French ADF grid, inspectors across communities consistently check: premises organization (separate sterilization area, forward-flow principle respected), equipment (validated autoclave, functional cleaning equipment), procedures (written protocol, traceability, biological controls), and documentation (sterilization register, autoclave maintenance log, staff training certificates).
Spain's over 40,000 registered dentists operate under the supervision of both the Consejería and the Colegio de Dentistas (dental professional college) in their province. The most frequently flagged issues during inspections: missing instrument-to-patient traceability, absent or incomplete written protocol, undocumented biological controls, and non-compliance with the forward-flow principle in the sterilization area. Under Real Decreto 192/2023 (implementing the EU MDR), reprocessing validation requirements have been strengthened, and inspections are expected to tighten further.
The protocol must define the traceability method used. Spanish regulations do not prescribe a format -- paper registers remain legally accepted. But their limitations are well documented: missing pages, illegible handwriting, forgotten entries, no instrument-to-patient link, risk of loss in case of disaster.
A digital register eliminates these risks. SecuSteri automatically imports the autoclave report, links each instrument to its cycle, and generates a signed, tamper-proof record. Each cycle is archived according to the plan's retention period, accessible at any time during an inspection.
