Malposition tooth (etopic eruption tooth). Malposition tooth are abnormal eruption teeth in the jaw. It can be: transversion or not (labioversion and hard palate). There are many causes of large tooth and small jaw; supernumerary teeth; primary teeth exist too long; odontoma, cleft palate or cleft lip. Malposition tooth causes effect to function and esthetics

Congenital absence of the primary canines is very rare. Congenital absence of primary teeth often causes their successors to not develop at all or affects the eruption of their successors. The purpose of this paper was to report the cases of 2 children with early eruption of the maxillary permanent canines at ages 4 and 6 years, respectively, following congenital absence of their maxillary primary canines, which are not common in earlier studies. Although tooth eruption and shedding exhibit some physiological variation, certain clinical cases are extreme. Premature eruption of the maxillary permanent canines may cause complications in terms of the space available for the eruption of adjacent teeth. Additionally, early eruption of permanent teeth increases the need for more careful oral hygiene. Therefore, the pediatric dentist must be alert to such rare cases.

Retained deciduous teeth are defined as the succedaneous permanent teeth have erupted while the primary teeth were retained, or the permanent teeth unerupted while the primary teeth remained in the permanent dentition. One case of multiple retained deciduous teeth was reported.

The ectopic eruption of a supernumerary tooth can occur in the sinonasal area, but due to its rarity, few cases of ectopic tooth eruption in the maxillary sinus have been reported. A fungus ball in the paranasal sinuses usually involves just one sinus, most frequently the maxillary sinus. Here, the authors present a case of an ectopic supernumerary tooth embedded in a fungus ball of the maxillary sinus.

OBJECTIVETo explore an effective orthodontic method for treating impacted dilacerated maxillary central incisors.

METHODS12 impacted teeth of 11 cases were chosen. The position of the impacted teeth and the relations with neighbour tissues were assessed by X-ray images, oral examination and plaster model, etc. The impacted teeth were induced to erupt with the closed-eruption technique and fixed orthodontic appliances, root canal therapy, apicoectomy and prosthetic treatment.

RESULTS12 impacted teeth were moved into arches, and the occlusal relationship was normal. There were no root resorption or conglutination in those impacted teeth. The labial impacted teeth of nine cases had bigger labial crown torsion. The root apexes of four impacted teeth were palpable under mucosa of the labial sulcus and operated by root canal therapy and apicoectomy. One of them received prosthetic treatment. Others (five cases) hadn't accepted root canal therapy, and were observed temporarily. The effects of two palatal impacted teeth was stable.

CONCLUSIONIt was a good method to expand indication with sequence orthodontic treatment. The impacted dilacerated maxillary central incisors could be aligned with good esthetical and functional effect.

Ectopic eruption of the maxillary permanent first molar refers to its deviation from the normal position due to some factors during the eruption process, which will lead to root resorption and early loss of the adjacent second primary molar, mesial movement itself, or serious malocclusion. To solve these problems, the Society of Pediatric Dentistry of Chinese Stomatological Association organized pediatric dental experts from 16 universities and hospitals, including West China Hospital of Stomatology, Sichuan University, Peking University School and Hospital of Stomatology, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine to carry out a panel discussions. The research, and diagnosis and treatment experiences of ectopic eruption of maxillary permanent first molar at home and abroad in recent years were also referred to. The present guideline was eventually developed for the reference of dental clinicians.
