Natal and neonatal teeth: A systematic review of prevalence and management
The purpose of this systematic review was to identify and review the literature concerning natal and neonatal teeth.
Study design and methods:
The literature search was conducted using several databases. Specific terms were used in the search, which includes articles from 1950 to 2011, supplementary searching by hand was also used. Relevant studies were selected according to predetermined inclusion criteria.
Studies meeting the inclusion criteria were only found with regards to prevalence and management of natal and neonatal teeth. Prevalence ranged from near 0 to 1:10 while extraction or maintenance of teeth comprised the management options.
There is significant need for further research, under specific scientific preconditions, to provide an evidence-based treatment for patients and to determine the prevalence of natal and neonatal teeth more precisely.

- "/pdj the mandibular central incisor region, with approximately 90% reported to be primary teeth and 10% supernumerary teeth; however, their cause is unclear, although considered to be related to heredity and the superficial position of the tooth germ [2e4]. Natal and neonatal teeth should be preserved to avoid future space management issues, while extraction should be considered when excessive mobility is seen to prevent aspiration or alleviate feeding difficulties such as RigaeFede disease, which causes sublingual ulceration of the tongue   . In the present report, we describe an uncommon case of an epulis that appeared after exfoliation of natal teeth in an infant Japanese boy. 2. Case report An 8-day-old infant boy was referred by a general practitioner to the Clinic of Pediatric Dentistry of Osaka University Dental Hospital for examination of natal teeth. "

ABSTRACT: An 8-day-old infant boy was referred to the Clinic of Pediatric Dentistry of Osaka University Dental Hospital for examination of natal teeth. An intraoral examination showed that two natal teeth had emerged into the oral cavity in the region of the mandibular primary central incisors, with the edge of one in the region of the mandibular right primary central incisor found to be in contact with the undersurface of the tongue. The affected tooth displayed severe mobility and the edge appeared to produce sublingual erosion; thus, it was extracted. In addition, a natal tooth in the opposite quadrant appeared to be attached to the surrounding gingiva with moderate mobility. Although we attempted to preserve that tooth, his parents reported that it was spontaneously exfoliated a few days later. Five months later, the patient returned to our clinic with swelling of the gingiva in the mandibular left primary central incisor region and a pedunculated epulis-like lesion was recognized in the gingiva of the mandibular left primary central incisor. A periapical X-ray photograph demonstrated thin radiopaque tissue with the appearance of a root in the area of the previously exfoliated natal tooth. We decided to remove the epulis-like lesion and associated thin hard tissue under local anesthesia. Histopathological analysis demonstrated that the lesion was composed of periodontal fibers covered by a layer of squamous epithelium cells, along with hemorrhage and vasodilatation under the mucosa. Taken together, the pathologist diagnosed the lesion as an epulis with inflammatory change.

ABSTRACT: A girl aged 0 years 11 months was referred to our clinic by a local pediatrician for examination of a missing tooth crown of a primary mandibular left lateral incisor. Our intraoral examination showed that seven primary incisors had emerged into the oral cavity, while no tooth crown was noted in the region of the primary mandibular left lateral incisor. A calcified structure was identified close to the gingival margin, which had a bone-like appearance and color, with no inflammation seen in the gingiva around the structure. Furthermore, the pulp space could be seen through the layer of hard tissue located close to the gingival region. A periapical radiograph taken at the first visit demonstrated a root-like structure with dentin and pulp, whereas enamel was not detected. The structure was speculated to be the root of the primary mandibular left lateral incisor, which was in the developmental stage. As there were no abnormal signs or symptoms, we decided to perform periodical examinations at 3-month intervals. Periapical radiographs taken at 1Y0M and 1Y7M showed root formation with no unusual conditions observed around the affected tooth.
