In the kit, the mobile telephone is clamped onto the base and the adapter includes a plate movably mounted on the base and on which the spacer is rigidly affixed.

Abstract: A dental retractor including: right, left, upper and lower flanges extending around a retractor opening and intended to rest, in a service position, on the right labial commissure, the left labial commissure, the central part of the upper lip and the central part of the lower lip respectively, of a user. The retractor including: a structure on which the flanges are attached. The retractor including: right and left handles rigidly attached to the right and left ends of the structure respectively, and/or to the right and left flanges respectively, shaped so as to extend outside the mouth of the user in the service position. The structure and/or the attachment of the flanges on the structure is/are shaped so that the horizontal closing force required to bring the right flange and the left flange 10 mm closer together is greater than 5 N.

Abstract: A dental photography kit that includes a support, taking the form of a housing. The support includes a support attachment part. The kit includes a dental retractor that defines a retractor opening and that includes a retractor attachment part that is removably attached to the support attachment part when the retractor is in the mounted position on the support. The kit includes a camera that is removably attached to the support in an operating position in which the camera is oriented to receive an at least partial image of the retractor opening. The retractor attachment part is articulated on the support attachment part.
