This randomized clinical trial will aim to evaluate the effect of DryShield isolation (DSI) and Rubber Dam isolation (RDI) systems on arterial oxygen saturation (SpO2), heart rate (HR), blood pressure (BP), behavior, subjective pain and discomfort, and time required among children with different airway patency based on Modified Mallampati classification (MMC). Healthy, cooperative 6-12-year-old children who need fissure sealant in at least two contralateral fully erupted permanent first molars will be included. The airway patency will be determined using MMC by two trained and calibrated dentists. Participants will be categorized based on their MMC score into patent airway (MMC Class I and II) and non-patent airway (MMC Class III and IV). During the treatment, the dental procedure will be videotaped, and the vital signs, including SpO2, HR, and BP, will be recorded every three minutes. A Validated Arabic Version of the Wong-Baker Pain Rating and the Face, Legs, Activity, Cry, Consolability (FLACC) scales will be utilized to record the participants' pain levels. In contrast, Frankl's Behavior will record their behavior during the dental procedure. Following the dental treatment, the participants' subjective pain and discomfort will be evaluated using a previously validated Arabic interview questionnaire.

Arterial oxygen saturation
Timeframe: Baseline before starting the dental procedure and then during the procedure at three-minute intervals until the removal of the isolation system.
Behavior
Timeframe: During the dental procedure.
Subjective pain and discomfort
Timeframe: immediately after the end of the dental procedure.
Time required in minutes
Timeframe: During the dental procedure.
Heart rate per minute (beat per minute)
Timeframe: Baseline before starting the dental procedure and then during the procedure at three-minute intervals until the removal of the isolation system.
Systolic and Diastolic blood pressure in millimeters of mercury (mmHg)
Timeframe: Baseline before starting the dental procedure and then during the procedure at three-minute intervals until the removal of the isolation system.
Behavioral pain and discomfort
Timeframe: During the dental procedure
