Abstract: A head for an oral care implement comprises a mounting surface and at least one tuft extending from the mounting surface. The tuft comprises a first group of filaments and at least a second group of filaments. The first group of filaments is surrounded by the second group of filaments. The filaments of the first group have a first length and the filaments of the second group have a second length, the first length being different from the second length. The difference in length between the first length and the second length is about 1.1 mm to about 1.9 mm.

Abstract: An oral care implement comprises a head and a handle, the head having a length extension and the handle having a length extension, the length extension of the head and the handle together defining an overall length extension of the oral care implement along a longitudinal axis. The overall length extension of the oral care implement is from about 194 mm to about 197 mm and the ratio of the length extension of the handle to the overall length extension of the oral care implement is from about 0.59 to about 0.65.

Abstract: An oral care implement comprises a head and a handle made of a first material. The handle has a distal end and a proximal end closest to the head. The handle comprises a thumb rest made of a second material, the second material being different from the first material. The thumb rest comprises an area from about 202 mm2 to about 360 mm2 and has a concave shape. The thumb rest comprises a portion being inclined with respect to a remaining portion of the thumb rest by an angle ? of about 20° to about 25°, the angle ? being defined by a first line and a second line. The first line extends between a most elevated point and a lowest point of the thumb rest, and the second line extends between the lowest point and an end point of the thumb rest, the end point of the thumb rest being closest to the distal end of the handle.

Abstract: A personal care device having a handle having an engagement portion and a persona care attachment are described. The personal care attachment has a housing attached to the engagement portion and a contact element carrier. The contact element carrier is movably coupled to the housing. A plurality of contact elements is arranged on the contact element carrier, and wherein the personal care attachment is driven at a frequency of between about 150 Hz to about 175 Hz and has a sound intensity level of less than about 75 dB(A).

Abstract: A head for an oral care implement comprises a mounting surface and at least one tuft extending from the mounting surface. The tuft comprises a first group of filaments and at least a second group of filaments. The first group of filaments is surrounded by the second group of filaments. The filaments of the first group have a longitudinal axis and a cross-sectional area extending in a plane perpendicular to the longitudinal axis, and the cross sectional area has a substantially circular shape with a first diameter. The filaments of the second group have a longitudinal axis and a cross-sectional area extending in a plane perpendicular to the longitudinal axis, and the cross sectional area has a substantially circular shape with a second diameter. The first diameter is smaller than the second diameter. The first diameter is about 0.15 mm to about 0.16 mm, preferably about 0.152 mm (6 mil) and the second diameter is about 0.17 mm to about 0.18 mm, preferably about 0.178 mm (7 mil).
