  In the world of dental sterilization assurance, biological indicators (BIs) are the most reliable method of verifying whether a sterilizer is functioning effectively. These indicators test the true effectiveness of a sterilization cycle by challenging it with highly resistant bacterial spores. But what happens when it's not the test BI that fails, but the control BI?

  While a failed test BI raises red flags for a potential sterilization breach, a failed control BI introduces an entirely different set of concerns. This article breaks down what a control BI is, what its failure means, and the exact steps your office should take to investigate and correct the issue.

  What is a Control BI?

  A Control BI is a self-contained biological indicator that is not exposed to the sterilization process. Its job is to serve as a positive control to prove that the spores

  When it comes to infection control in dental settings, the science behind your sterilization materials matters. One of the most advanced and trusted materials in the field is SMMS, short for Spunbond-Meltblown-Meltblown-Spunbond. This multi-layered nonwoven fabric plays a critical role in keeping sterilized instruments safe until use.

  So, what exactly is SMMS, and why does it outperform traditional single-ply wraps?

  SMMS: A Four-Layer Engineered Barrier

  SMMS is a composite structure made of:

  • Two outer spunbond layers
  • Two inner meltblown layers

  Each layer serves a distinct and essential purpose:

  1. Spunbond Layers (Outer

  Sterilization wrap is a critical element to instrument reprocessing. When used correctly, it creates a critical barrier that protects sterile instruments from contamination until point of use. But what happens when your SMMS wrap starts melting in the autoclave? It’s more than frustrating, it’s a red flag. This guide walks you through common causes and solutions when your sterilization wrap doesn’t perform as expected.

  Understanding the Material: What Is SMMS Wrap?

  SMMS (Spunbond-Meltblown-Meltblown-Spunbond) is a four-layer nonwoven material commonly used in sterilization wrap. It's engineered to resist microbial penetration and mechanical wear while allowing steam to pass through during sterilization. When SMMS wrap melts, the problem usually isn’t the wrap itself, it’s the processing conditions.

  Troubleshooting: Where Things Go Wrong

  Here’s a practical breakdown of what to investigate if your SMMS wrap is melting or distorti

• Animals and Plants in the Dental Office: What IPAC Standards Say

  Posted: March 11, 2026

  Infection Prevention and Control (IPAC) is at the heart of safe dental care. While much of the conversation focuses on sterilization, PPE, and operatory protocols, questions often arise about something more everyday: Can we have animals or plants in the dental office?

  The answer lies in understanding accessibility laws, IPAC standards, and the principle that everything in the patient care environment must be capable of being cleaned and disinfected.

  Animals in the Dental Office

  Service animals, such as trained dogs assisting patients with disabilities, are permitted in dental offices under accessibility and inclusion laws. These animals must be allowed entry and cannot be denied access to care.

  Emotional support or personal pets, however, are not protected under these laws and are not permitted in dental offices unless they qualify as certified service animals.

  That said, staff members sometimes wonder if they can bring
