Brushing duration of Philips Sonicare

FlexCare+ versus a manual toothbrush

Milleman J, Putt M, Jenkins W, Jinling W, Strate J. Data on le, 2009

Objective To compare the brushing duration with the Sonicare FlexCare+ versus a manual

toothbrush after two weeks of home use.

Methodology Fifty-six healthy subjects (24 females, 32 males) were enrolled in an IRB-approved

randomized, parallel-design two-week study. At Visit 1, eligible subjects were

randomized to either Sonicare FlexCare+ Gum Care mode or a manual toothbrush

and were provided brushing instructions. They performed an on-site brushing session

immediately thereafter, which was timed and video recorded from behind a one-way

mirror for duration data collection. A home-use period of two weeks commenced

with the assigned product in order for subjects to familiarize with the device. At

Visit 2, the subjects were asked to brush with their assigned product. The recording

procedure was repeated. Subjects were remunerated and dismissed. Statistical

analysis was performed using the Wilcoxon signed rank test.

Results Twenty-eight subjects were randomized to Philips Sonicare FlexCare+ and twenty-

eight to a manual toothbrush. A longer median brushing duration was observed

for Philips Sonicare FlexCare+ users at both time points. Sonicare FlexCare+ (180

seconds) compared to a manual toothbrush (90 seconds) at Visit 1 (p<0.0001).

Sonicare FlexCare+ (181 seconds) compared to a manual toothbrush (71 seconds)

at Visit 2 (p<0.0001).

Conclusion Subjects brushing with Philips Sonicare FlexCare+ using Gum Care mode brushed

signicantly longer (p<0.0001) than with a manual toothbrush following

a familiarization period of two weeks.

Do you have a question about the Philips FlexCare+ and is the answer not in the manual?

This document describes a study comparing the brushing duration of the Philips Sonicare FlexCare+ toothbrush with a manual toothbrush. The primary function of the Philips Sonicare FlexCare+ is to provide an effective and potentially longer brushing experience compared to traditional manual toothbrushes.

Function Description

The Philips Sonicare FlexCare+ is an electric toothbrush designed to facilitate oral hygiene. While the document doesn't explicitly detail its internal mechanisms, it highlights its ability to encourage users to brush for a longer duration. This suggests that the device likely incorporates features that guide users to maintain brushing for an extended period, which is generally recommended for optimal plaque removal and gum health. The study specifically mentions the "Gum Care mode" of the Sonicare FlexCare+, indicating that the device offers different operational modes tailored to specific oral care needs. This mode likely focuses on gentle yet effective cleaning along the gumline, which is crucial for preventing gingivitis and promoting healthy gums. The core function, therefore, is to deliver a superior and more consistent brushing performance than a manual toothbrush, primarily by influencing user behavior regarding brushing duration. The device aims to make the recommended brushing time more achievable and perhaps more comfortable for the user.

Usage Features

The study provides insights into how the Philips Sonicare FlexCare+ is used and its impact on user behavior.

Encouraged Longer Brushing Duration: A key usage feature is its ability to promote longer brushing times. The study found that users of the Sonicare FlexCare+ brushed for significantly longer periods (180-181 seconds) compared to manual toothbrush users (71-90 seconds). This suggests the device incorporates features that make it easier or more intuitive for users to reach and maintain the recommended two-minute brushing time, and even exceed it. This could be due to built-in timers, quadrant pacing, or a more engaging brushing experience that encourages extended use.
Gum Care Mode: The mention of "Gum Care mode" indicates that the Sonicare FlexCare+ offers specialized brushing programs. Users can select this mode for a targeted approach to gum health, which might involve a different intensity, frequency, or pattern of brush head movement. This provides versatility, allowing users to customize their brushing experience based on their specific oral health requirements.
Familiarization Period: The study included a two-week home-use period for subjects to "familiarize with the device." This implies that while the Sonicare FlexCare+ is designed for ease of use, there might be a slight learning curve associated with its electric operation, different modes, or the sensation of sonic vibrations, compared to the familiar action of a manual toothbrush. This familiarization period is a practical aspect of its usage, ensuring users can effectively integrate the device into their daily routine.
On-site Brushing Sessions: The methodology describes subjects performing "on-site brushing sessions" which were timed and video recorded. While this is part of the study design, it highlights the typical usage scenario: the device is used for daily brushing. The fact that these sessions were observed suggests that the device's operation is straightforward enough for users to perform independently after initial instructions.
Assigned Product for Home Use: Subjects were provided with the "assigned product" for home use. This indicates that the device is intended for regular, unsupervised daily use in a home environment, forming part of a consistent oral hygiene regimen.

Maintenance Features

The provided document does not explicitly detail maintenance features of the Philips Sonicare FlexCare+. However, based on the nature of electric toothbrushes, certain general maintenance aspects can be inferred:

Brush Head Replacement: Electric toothbrushes, including sonic models, typically require regular replacement of the brush head. This is essential for maintaining optimal cleaning performance and hygiene. Over time, bristles wear out and become less effective at removing plaque. While not stated, it is highly probable that the Sonicare FlexCare+ has detachable brush heads that can be easily replaced by the user.
Charging: As an electric device, the Sonicare FlexCare+ would require charging. This usually involves placing the toothbrush handle on a charging base. The frequency of charging would depend on battery life and usage patterns. The document does not specify the type of charger or battery life, but it's an inherent maintenance aspect of any rechargeable electric toothbrush.
Cleaning the Device: Regular cleaning of the toothbrush handle and brush head (after each use) is crucial for hygiene. This typically involves rinsing the brush head thoroughly under water and wiping down the handle to prevent the buildup of toothpaste residue or other debris. While not explicitly mentioned, this is a standard maintenance practice for all toothbrushes, especially electric ones where residue could accumulate around the charging contacts or internal components.
Storage: Proper storage, often on its charging base or in a designated holder, contributes to the longevity and hygiene of the device. This prevents the brush head from coming into contact with other surfaces and allows it to air dry.

In summary, the Philips Sonicare FlexCare+ is presented as an advanced oral care device that significantly improves brushing duration, likely through integrated guidance and specialized modes like Gum Care. While the document focuses on its performance benefits, the usage implies a straightforward daily routine with a short familiarization period, and maintenance would typically involve brush head replacement, charging, and general cleaning, common to most electric toothbrushes.
