Abstract: A device for centering and guiding at least one drill bit of a dental handpiece when drilling a hole in the jaw of a patient in cooperation with a surgical guide equipped with a tubular drill bushing. A support holds a tubular guide sleeve permanently in a coaxial and sliding position with respect to the drill bit. The tubular guide sleeve is able to engage with slight play in the tubular drill bushing. The support insures the engagement of the guide sleeve in the tubular drill bushing at the latest when the drill bit starts to drill in the patient's jaw, thus insuring the centering and guiding of the drill bit.

Abstract: A dental handpiece carries a drill and drives it in relative motion in a direction of penetration. The handpiece includes a body with a proximal end and a distal end, a removable head connected to the body's distal end, able to hold the drill, abutment means fixed on the dental handpiece by fixation means and able to limit the depth of penetration of the drill in the body of a patient. The abutment means, protruding from the dental handpiece, are fixed and locked on the dental handpiece by locking means which are actuated by the simple movement of joining the head to the body.

Abstract: UV-photoprotective, topically applicable cosmetic/dermatological compositions contain: (a) at least one dibenzoylmethane compound, (b) at least one 1,3,5-triazine compound that is photosensitive in the presence of a dibenzoylmethane compound, and (c) at least one siliceous s-triazine compound substituted with two aminobenzoate or aminobenzamide groups, or a tautomeric form thereof, the 1,3,5-triazine compounds being improvedly photostable in such compositions.

Abstract: The bone recovery device of the invention comprises an axial main body with an axial cavity passing through it, a front connector incorporating an axial passage and adapted to be fixed to the main body, a filter with a tubular filtering wall adapted to be fitted into the main body, and a scraper piston that slides inside the filter. The scraper piston blocks the end of the filter, and a radial outlet is provided in the axial main body, with an annular cavity left free around the filter between the filter and the axial main body. A canula is inserted into the distal end of the filter. The recovery device may therefore be used to recover bone retained by the filter during aspiration through the canula by the radial outlet, and bone fragments may be extracted by sliding the piston and withdrawing the canula. The recovery device may therefore be used several times without demounting it.

Abstract: Photostable UV-photoprotecting cosmetic sunscreen compositions contain (a) an effective UV-photoprotecting amount of at least one dibenzoylmethane compound sunscreen, (b) an effective radiation-photostablizing amount of at least one pyrrolidinone compound having the formula (I) below: and, advantageously, at least one liquid fatty phase and at least one lipophilic active sunscreen agent of low solubility, formulated into (c) a cosmetically acceptable support therefor.

Abstract: A device (14) belonging to a first network is controlled from a terminal (13) able to communicate through a second network by means of a communication protocol. The device is adapted to implement at least one application able to be remotely controlled through the first network, by a control entity (15), by means of a control protocol. A network entity connects the first and second networks. This network entity receives, from the terminal, a control message (31) conforming with the communication protocol. Then, it translates the control message conforming with the communication protocol into a translated control message (32) conforming with the control protocol adapted for controlling the application. Then, it transmits the translated control message to the control entity.
