A saliva ejector is a small, low-volume suction device used in dentistry to remove saliva and light fluids from the mouth. It is commonly placed along the cheek or floor of the mouth during routine dental procedures. Its main role is to help keep the treatment area drier and easier to see. It is used in dental exams, cleanings, and many restorative (filling) appointments.
cotton roll isolation is a method dentists use to keep teeth drier during treatment by placing small, absorbent cotton rolls inside the mouth. It helps control saliva and moisture around the tooth being worked on. It is commonly used during fillings, sealants, and other routine procedures where a reasonably dry field is needed. It is often combined with suction and cheek or tongue retraction for better visibility and access.
isolation is the set of techniques used to keep a tooth and the surrounding working area dry, clean, and accessible during dental treatment. It commonly involves tools like a rubber dam, cotton rolls, suction, and cheek retractors. Dentists use isolation during procedures where saliva, blood, or tongue movement could interfere with materials or visibility. It is a routine part of many restorative and endodontic (root canal) workflows.
rubber dam is a thin sheet used to isolate one or more teeth during dental treatment. It creates a barrier that helps keep the working area dry and easier to see. It is commonly used in restorative dentistry (fillings) and endodontics (root canal treatment). It is held in place with small accessories such as a frame and a clamp.
A glutaraldehyde desensitizer is a dental liquid used to reduce tooth sensitivity, especially on exposed dentin. It is most commonly applied by dental professionals during restorative procedures or before placing indirect work like crowns. Its goal is to calm sensitivity by sealing or reducing fluid movement inside tiny dentin channels. It is used in clinics, not as an at-home product.
A desensitizer is a dental material used to reduce tooth sensitivity, most often from exposed dentin. It is commonly applied in the dental office after cleaning, during restorative procedures, or after periodontal care. Some desensitizer products are painted on and set chemically, while others are light-cured. In simple terms, it helps “seal” sensitive tooth surfaces so triggers like cold air or sweets are less likely to cause pain.
wet bonding is a dental adhesive technique where dentin is kept slightly moist during bonding. It helps resin-based adhesives penetrate etched dentin and form a stronger seal. It is commonly used in composite (tooth-colored) fillings, repairs, and bonding procedures. The goal is reliable adhesion while reducing gaps at the tooth–restoration interface.
The oxygen inhibition layer is a thin, tacky surface film that can remain on light-cured dental resins after curing in air. It forms because oxygen in the air interferes with the final surface polymerization (hardening) of resin materials. It is most commonly discussed with composite fillings, bonding agents (adhesives), and resin-based sealants. Clinicians may preserve it between layers for bonding, or remove it when finishing the outer surface.
The air inhibition layer is a thin, sticky surface film that can remain on light-cured dental resins after curing. It happens because oxygen in the air interferes with the final part of resin polymerization at the surface. It is commonly discussed with composite fillings, bonding agents (adhesives), sealants, and some resin cements. Clinicians may use it intentionally between layers or remove it when a final hard, polished surface is needed.
A smear plug is a small, localized “plug” of resin material placed into a prepared tooth area. It is most commonly discussed in relation to composite (tooth-colored) restorations. The goal is to help the material adapt closely to the tooth surface in tight or irregular areas. The term is often informal and may be used differently by different clinicians.
