The etiology, treatment, and prevention of nursing caries.

Despite the decline in the dental caries rate over the last 20 years, one particular segment of the population does not seem to have benefited significantly. This group is composed of infants and children afflicted with widespread caries destruction of deciduous teeth, most commonly referred to as nursing caries. Untreated cases of the disease have resulted in pain, loss of function, premature tooth loss, delays in development, hearing and speech difficulties, and psychosocial disturbances. Among these children are some of the most paramount problems that dentistry has had to face. This article specifically discusses the epidemiology, clinical characteristics, etiology, risk factors, treatment, and prevention of nursing caries, to serve as an up-to-date reference for the general dentist who treats this patient population.

[Space maintenance following the premature loss of temporary teeth].

Despite contemporary techniques, we still don't have the ability of saving all deciduous teeth in their place on the dental arch until the time of physiological loss. A premature loss of temporary teeth interferes with the harmony of the adult dentition. The principal consequence of this premature loss is crowding, caused by migration of the adjacent teeth. This article ames to guide our policies in the decision making process whether or not maintaining space, in causes of premature loss of one or more deciduous teeth.

Sexual dimorphism in the tooth crown dimensions of the second deciduous and first permanent molars of Taiwan Chinese.

Sexual dimorphism in the crown components in the second deciduous molar (dm2) and the first permanent molar (M1) of the dental casts taken from Chinese living in Kaohsiung (Taiwan) was investigated. Mesiodistal and buccolingual crown diameters, and 4 main-cusp sizes in the maxillary molars and mesiodistal diameters of the trigonid and talonid in the mandibular molars were measured using a digital caliper (0.01 mm). Percentage sexual differences were calculated. With the exception of trigonid mesiodistal diameters, the mean values of males were larger than females. In both of dm2 and M1 the mean values of the trigonid mesiodistal diameters were slightly larger in females than in males, but the differences were not significant. Percentage sexual dimorphism was smaller in the mesiodistal diameters than in the buccolingual in both dm2 and M1. The crown components showed larger sexual difference in dm2 than in M1, while in the maxilla the external crown size showed larger sexual difference in M1 than in dm2. The buccal cusps showed larger sexual difference than the lingual in the maxillary molars and the talonid showed larger sexual difference than the trigonid in the mandibular. Sexual dimorphism of dm2 and M1 in their crown components displayed similar pattern, although the different degree was noted. This result is thought to relate to the fact these molars belong to the first dentition embryologically.
