Safety and effectiveness of an innovative SS-suction device to control moisture in dental procedures

Abstract

Control of moisture is critical for retention of sealants, which can reduce the incidence of caries in high-risk groups. Objectives: We investigated the safety and efficacy of the novel SS-suction device in the laboratory and a small clinical trial in children aged 6 to 8-years-old. Methods: First, a laboratory test of 52 SS-suction devices was conducted to determine the pressure generated by the chin plate to maintain suction at different intervals and to determine the pressure resistance of the spring to maintain suction in a child's mouth. Second, 12 healthy children with sound lower molars participated in a clinical trial of the use of SS-suction during sealant application. Results: The laboratory test showed that when pressed to the maximum distance of 25 mm, the chin plate produced a pressure of 247.5 ± 116.6 mmHg. At this pressure, the SS-suction could be used safely for up to 120 min without damaging the soft tissues. In the clinical study, the dentists inserted and removed the SS-suction in 7.80 ± 2.48 s. The range by which the chin plate was pressed down varied between 0 and 13 mm. The highest pressure on the skin was 120 mmHg (at 13 mm) and the device effectively maintained suction and effectively removed water and saliva. The time required to apply sealant was 7.01 ± 2.26 min. Conclusions: The SS-suction is a safe, effective device for two-handed application of sealants in children, with no negative side effects. Clinical significance: We demonstrate the unique SS-suction device can quickly drain water and saliva to help dentists treat young patients using a two-handed approach; this device provides good control of moisture during sealant application. The device prevents the tongue and cheeks from interfering with the operation area, reduces tension, and does not require a dental assistant.
