[Risk of oral piercing].

Oral and facial piercing with different kinds of body art are being observed more frequently in medical and dental practices. Principally, piercing is not a new form of body art and is traditional in different geographical areas. Various materials are used. Besides tongue and lip piercing, different locations of the face such as the eyebrows and the nose are anatomical areas of piercing. The aim of this article is to demonstrate different forms of oral piercing, illustrated by own observations. The piercing procedure is briefly described. Piercing is usually performed without local anaesthesia and stepwise. In a literature review, the possible risks and complications are summarised. Postprocedural complications are oedema, haemorrhage and infection. Other complications are foreign body granulomas or allergies, particularly against nickel. Dentists, and oral- and maxillofacial surgeons should be in a position to advise patients with oral or facial piercings or those who plan to have this type of body art performed.

Clinical management of the mandibular molars.

The complex variety of clinical problems posed by the lower molars requires maximum care in diagnosis and in treatment planning. In this article several therapeutic solutions to these problems are presented. The need to treat positional anomalies of the second molars and to control their drifting in cases of bracing and mandibular insertion, may be an effective auxillary means of treatment of those malocclusions in which lengthening of the dental bracing zones is indicated.

An experimental study of increased vertical dimension in the growing face.

Five juvenile rhesus monkeys were used in an experiment designed to study the structural adaptations in the craniofacial complex that resulted from increases in vertical dimension. The bite was opened 2,3,10, or 15 mm. by means of cast bite splints cemented on the maxillary arch. Adaptations were monitored in these animals by means of serial cephalometric radiography with metallic implants. The results of this study indicate that any change in the vertical dimension of the face results in specific structural adaptations throughout the craniofacial complex. The most significant adaptation occurred in the maxillary region, in which the normal downward displacement of this region was decrease and the anterior displacement was increased. Adaptation were less evident in the mandible, except in those animals in which a severe bite opening was produced; resorption in the region of the gonial angle was evident. Dentitional adaptations were of secondary importance. This study demonstrates that the maxillary complex is a very plastic structure which responds to changes in bite opening and altered muscle length. The clinician should be aware of the changes that result from various alterations of vertical dimension to make sure that these changes are not antagonistic to his over-all treatment goal. He may also take advantage of these changes when designing treatment strategies for certain clinical cases.

Short-term changes in the mesiodistal position of teeth following removal of approximal contacts in the monkey Macaca fascicularis.

A capacitance transducer was used to measure the changes in the distance between pairs of adjacent teeth following the removal of tooth contact. Ten pairs of incisors and cheek teeth were studied over periods of several hours in three adult monkeys. Compared with minor changes in control tooth pairs, there was a sustained approximation of the capacitance plates for periods up to 2 h. Removal of tooth contacts with the teeth adjacent to the test pairs of teeth caused separation of the plates. It is proposed that removal of approximal tooth contact allows the transseptal fibre system to contract and produce approximation of the adjacent teeth.
