Catalogue of Etruscan and Roman-era dental appliances

Marshall Joseph Becker, Jean MacIntosh Turfa
This use of gold wire to fit a replacement tooth is the only example yet known from Rome (or Italy), and was excavated under controlled conditions from a tomb of the first–second century ce in the Collatina necropolis of Rome. A woman who died around 50 years of age was wearing the appliance to replace a mandibular central incisor probably lost to periodontal disease. If such appliances had been common, more examples should have survived. This Roman example of the Early Imperial Age falls within the same medical tradition known from the Hippocratic corpus, and also reflects specimens buried in the eastern Mediterranean, Levant and Egypt.
Dental Anatomy and Occlusion

Overbite is the amount of vertical overlap between the maxillary and mandibular central incisors, expressed as a percentage or in millimeters (Fig. 4-13). A normal overbite is 1 to 3 mm. When the upper incisors overlap most of the labial surface of the lower incisors, it is called a deep bite. An anterior opening with no overlap is an open bite, which is measured in millimeters (Fig. 4-14). Open bites may be of a dental or skeletal nature. An anterior dental open bite may include only a few teeth, and it is usually caused by habits (such as thumb sucking or tongue thrusting) or other factors. An anterior skeletal open bite might be caused by hyperdivergence of the maxilla and mandible (apertognathia), which is usually more difficult to treat orthodontically and might require orthognathic surgery. When there is no contact between posterior teeth, it is called a posterior open bite.
Sex-specific reference values for the crown heights of permanent anterior teeth and canines for assessing tooth wear

The body height had a significant correlation with clinical crown heights of maxillary and mandibular canines (Pearson correlation coefficient r = 0.294; p < .001 and r = 0.383; p < .001, respectively) and maxillary lateral and central incisors (r = 0.208; p = .007 and r = 0.206; p = .008, respectively), but not with crown heights of mandibular lateral and central incisors (r = 0.122; p = .115 and r = 0.055; p = .482, respectively) (Figure 2). However, men were an average of 11.4 cm taller than women (95% confidence, 9.4–13.4 cm; independent t-test), and stepwise multiple regression analysis showed that only gender was significantly related to the crown height of each tooth group, except for mandibular central incisors (adjusted R2 = ranged from 0.03 to 0.23; p < .05).
A foetus with a mass in the oral cavity: a rare case of oral eruption cyst

An EC accompanying an erupting primary tooth forms shortly before the tooth appears in the oral cavity. Mandibular central incisors and permanent first molars are the most common sites for EC (Nagaveni et al.2011). Ultrasound can help to detect the mobility, extent of involvement, and tissue characteristics of this lesion. In our case, an EC during the foetal period was detected as a lesion that comprised a solid mass and cystic fluid sprouting from the body of the mandible. Correspondingly, 2D sonography revealed it as a fixed homogeneous hyperechoic mass circumscribed by a layer of sonolucent space originating from the mandible. 3D imaging confirmed the relationship between the lesion and other tissue structures by creating a multiplanar reconstruction view (Fenster et al.2011).
Immediate and short-term effects of phototherapy on pain, muscle activity, and joint mobility in women with temporomandibular disorder: a randomized, double-blind, placebo-controlled, clinical trial

The evaluation of maximum vertical mandibular movement was performed using two measures: maximum opening without pain, for which the volunteer was instructed to place the mandible in a comfortable position and open her mouth as wide as possible without pain and without assistance; and maximum opening even with pain, for which the volunteer was instructed to place the mandible in a comfortable position and open her mouth as wide as possible even if feeling pain. All measurements were recorded in millimeters with the aid of digital calipers (Starrett®, Athol, MA) positioned between the maxillary and mandibular central incisors. The same procedure was performed three times, with a one-minute interval between readings. The mean of the three readings was used for the comparison between baseline and post-treatment evaluations.
