Patient Preference, Retention, Time
Conditions
Brief summary
The trial aimed to evaluate the sealant retention, patient's preference and chair time needed during pit and fissure sealant placement under two isolation techniques \[Dryshield system (DS) and cotton roll isolation (CRI)\] in a university setting.
Detailed description
In children, 80-90% of dental caries is found in the pits and fissures of the posterior permanent teeth. Pit and fissure sealants (PFS) can be used effectively to prevent dental caries. When applied correctly, dental PFS accomplish three main objectives: preventing dental caries development, hindering dental caries development in its initial phases, and inhibiting the spread of bacteria that cause dental caries. To be effective, PFS need to be applied under sufficient moisture control around the specific teeth undergoing treatment. Therefore, proper isolation of the teeth is one of the most important steps when placing sealants to ensure their retention. Cotton roll isolation (CRI) has been widely used for sealant placement, and is the most common method among pediatric dentists. However, the placement of cotton rolls on the lateral part of the tongue or inadequate isolation during CRI has both been reported to produce gagging, tasting the contents and requiring frequent replacement of the wet cotton rolls. A previous study demonstrated that new moisture control systems such as Isolite, produce sealant retention rates comparable to cotton roll isolation, while decreasing procedure time. DryShield (DS) has recently been introduced as an all-in-one isolation system. It is similar to the Isolite as it combines the tasks of fluid evacuation, tongue and cheek retraction, and serves as a bite block, but differs in that it is autoclavable and does not provide illumination. Its design allows it to suction and isolate half the oral cavity at a time. Therefore, it should presumably facilitate sealants placement under a more controlled environment, while reducing chair time for the dentist. Few trials have compared the PFS chair time and patient acceptance of DS to the CRI. The goals of this study were to evaluate patients' preferences, time efficiency, and retention of PFS using DS compared to CRI in a single randomized clinical study.
Interventions
DEVICEDryshield
DryShield combines the tasks of high-suction evacuator, saliva ejector, bite block, tongue shield, and oral pathway protector in one easy-to-use device. The DryShield solution® is a patented autoclavable isolation system (MA, USA)
DEVICECotton roll isolation
Cotton Roll Isolation requires placing cotton rolls along the buccal mucosa, especially over the parotid glands ducts for maxillary teeth. For the mandibular teeth, the cotton rolls are placed in the buccal vestibule and the floor of the mouth (between the lower buccal mucosa and underneath and/or between the tongue). With this technique, a high-speed evacuation of saliva and water is used.

Primary purpose
PREVENTION
Masking
SINGLE (Outcomes Assessor)
Masking description
The participants, care providers and the principle supervisor were not blinded since they know which isolation technique was used during the placement of sealant. But the outcome assessor was blinded and he assessed the sealants placement after 6, 12, and 18 months.
Intervention model description
All eligible study participants were randomised using simple block random allocation to ensure balanced randomization for each isolation system. Each participant was given an envelope and a printed participant number. Each number identified the isolation technique used for sealant placement and the isolation application sequence to be used.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Fissure Sealant Retention at 6 months | Change in sealant retention at 6 months | Patients were clinically evaluated by a study supervisor as a blinded outcome assessor after 6 months of sealant placement. The evaluation was according to Simonsen's criteria: Completely retained, Partially retained, or Missing. |
| Change in Fissure Sealant Retention at 12 months | Change in sealant retention at 12 months | Patients were clinically evaluated by a study supervisor as a blinded outcome assessor after 12 months of sealant placement. The evaluation was according to Simonsen's criteria: Completely retained, Partially retained, or Missing. |
| Change in Fissure Sealant Retention at 18 months | Change in sealant retention at 18 months | assessor after 18 months of sealant placement. The evaluation was according to Simonsen's criteria: Completely retained, Partially retained, or Missing. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Placement time of sealants using Dryshield vs Cotton roll isolation | 0 Day (After the completion of initial sealant placement and removal of the isolation device) | The placement time for sealant application was recorded with a stopwatch by the dental assistant as follows for the two techniques: the insertion of the isolation aids (DS or CRI) in the oral cavity constituted the start time, and the end time was when the isolation system was completely removed from the participant's mouth after the sealants application. |
| Patient preference for Dryshield or Cotton roll isolation | 0 Day (After the completion of initial sealant placement and removal of the isolation device) | A six-item interview-based questionnaire was administered to assess participants' acceptance of the isolation technique used. |
