a 7.5 year-old girl was seeking orthodontic treatment because of severe ectopic eruption of maxillary first permanent molars. it was a rare case that represented approximately horizontal view in panoramic radiograph. the severity of problem was high, but since the patient had maxillary deficiency, it was important to perform the treatment without extraction. treatment began with extraction of u...

The mechanism of root formation and tooth eruption is a complex process which is not fully understood. Prior to a tooth emerging into the oral cavity, root genesis is initiated by derivatives of the enamel organ. The dental follicle mediates an eruption pathway allowing for movement of the developing tooth in a coronal direction. As the tooth moves towards the oral cavity, root formation occurs...

Ectopic eruption into the dental environment is common, whereas eruption into other sites is rare. Diverse anatomical locations such as the mandibular condyle, coronoid process, palate, maxillary sinuses and nasal cavity can infrequently be the site of ectopic tooth eruption. One of the nondental sites for ectopic eruption is the maxillary sinus. Here, we present a case of dentigerous cyst with...

Eruption cysts are benign cysts that appear on the mucosa of a tooth shortly before its eruption. They may disappear by themselves but if they hurt, bleed or are infected they may require surgical treatment to expose the tooth and drain the contents. Here we present 2 case reports of eruption cysts presenting with different chief complaint. The treatment included incising the eruption cyst and ...

Abstract Impaction of maxillary central incisors is not common. Treatment of an impacted central incisor is challenging as it relates to facial esthetics and dental function. Although impaction of permanent teeth is rarely diagnosed in mixed dentition period, an impacted central incisor is usually diagnosed when there is a delay in the eruption of tooth. Tooth impaction may result from...

The aim of the present paper is to determine the beginning, order, median time, termination, dynamics, continuity and intensity of the permanent tooth eruption, as well as its calendar, in a sample of Zagreb children. The study included 2768 children (1398 boys and 1370 girls). All subjects were classified in one-year age groups. The continuity of tooth eruption occurs from 5.1 years to 14.97 y...

Several different theories have been advanced to explain the mechanism of tooth eruption. This has been defined by Massler and Schour' as the process whereby a developing tooth migrates from an intraosseous location in the jaw to its functional position within the oral cavity. They also evaluated each of these theories with regard to clinical and experimental observations. Substantial factual e...

In ungulates, a set of deciduous teeth is replaced by a set of permanent teeth during their first 2 years of life. Little is known about factors causing variation in timing of tooth eruption, but overall size, condition or mineral deficiencies may play a role. The pattern of incisor (I) and canine (C) eruption was investigated in 2241 yearlings from five populations of red deer Cervus elaphus i...

OBJECTIVE The aim of this study was to present a literature review and case series report of tooth abnormalities in congenital infiltrating lipomatosis of the face (CIL-F). METHODS Four typical cases of CIL-F are presented. Tooth abnormalities in CIL-F documented in the English literature are also reviewed. The clinical and radiological features of tooth abnormalities are summarized. RESULT...
