Why isolation performance matters in restorative dentistry
Effective isolation is crucial for successful restorative dentistry. Properly controlling moisture and microbes helps to establish a dry working field to ensure reliable and high-quality treatment results. [i] Dental dams offer an engineered solution for this, preventing patients from aspiring or ingesting foreign objects, protecting soft tissue, and even reducing risk of infection.
It is integral that the material offers dependability once tension is applied. Elasticity and tear resistance are both important factors that can significantly impact whether isolation is maintained throughout a procedure, or whether it is compromised. Therefore, choosing the right dental dam is a big decision.
Advances in engineering
By excluding moisture and saliva from the tooth being restored, the bond between the restorative material and tooth is improved, whilst also minimising infection risk. Poor bonding can compromise the restoration, both in terms of success and longevity compared to other isolation materials.
Other methods of isolation include the use of cotton rolls combined with aspiration by saliva ejectors. However, although this method is relatively low-cost and widely available, cotton rolls are clinically inefficient due to the frequent requirement of replacing sodden ones throughout treatment to ensure a dry operating field.[ii]
Research indicates that restorations might be more likely to remain in place and be in good condition after six months when using a rubber dam instead.i Dental dams also offer reassurance to dental professionals regarding the spread of pathogens too as it has been reported that up to 70% of airborne particles could be reduced around a 3-ft diameter of the operational field when a dam is used.[iii]
Having been introduced to the dental profession by Dr Sanford C Barnum on 15 March 1864,[iv] the application of dental dams has been significantly improved and is now used frequently as a more practical approach to isolation.
Key characteristics for efficient workflows
Restorative cases are often time consuming and demand uninhibited, broad access to the oral cavity.[v] This requires the dental dam material to demonstrate excellent, long-term elasticity and stability under tension.[vi] Elasticity allows the dental dam to stretch over clamps and tooth contours without compromising soft tissue or access, meaning its elasticity must be controlled and adaptable to avoid thinning or loss of tension.vi
Additionally, tension is linked to tear resistance, whereby tears commonly occur at specific points of stress.[vii] Materials that offer consistent thickness and controlled elasticity allow the forces to be distributed more evenly, which reduces the risk of failure.[viii] As even the most minor tears can interrupt the continuum at any point during the procedure, strong resistance is integral. This could otherwise compromise the isolation of the tooth and subsequently impact the time-frame and potential success of the treatment.
Recent advances in non-latex, synthetic dental dams have introduced greater benefits beyond a solution to latex allergies. Unlike natural latex designs, the synthetic approach can be engineered to deliver greater elasticity and tear resistance. This level of consistency and reliability is highly valuable in restorative dentistry as predictable handling is crucial for efficient workflows and continuous aesthetic quality.
Material predictability for the best results
Using dental dams – with this predictable material behaviour – significantly reduces interruptions during treatment. Dental dams that uphold tension maintain greater consistency during treatment for many different patients. When clinicians are less likely to pause due to tears or overstretched isolation tools, focus and workflows are less frequently interrupted. Though these disruptions might be minor in moment, their consequences can greatly compromise results – increasing cognitive load and chair time whilst diminishing patient satisfaction.[ix]
Selecting the best isolation materials
When selecting a dental dam product for use in your practice, considering these factors is important for continuous success in treatments.
The new HySolate SyntX Dam from COLTENE is the most advanced latex free dental dam for faster isolation and confident retraction. With exceptional tear resistance, the HySolate SyntX Dam is engineered with polyisoprene – combining incomparable elasticity and tear resistance without allergy risks. The dam also comes with a pre-printed template, making them easy to learn and use, whilst also streamlining workflows further by minimising preparation time. COLTENE supports stable isolation throughout treatment with its revolutionary HySolate SyntX Dam.
Stable isolation supports predictable restorations
Restorative success is impacted not only by clinician technique and skill, but by the materials used throughout the process. Dental dams that maintain elasticity and tension – and that provide excellent tear resistance – allow procedures to flow more smoothly and predictably. By working with controlled materials, workflow predictability and efficiency is enhanced significantly.
