Tooth autotransplantation is one of the methods used for tooth loss rehabilitation in children. Premolars are usually used as autotransplants requiring esthetic alterations. The purpose of this paper is to present an innovative, alternative and inexpensive way to restore auto-transplanted teeth using the crown of the tooth of the recipient site. A seven-year-old male with a non-contributory medical history presented with an intrusion of his permanent maxillary right central incisor. The tooth underwent orthodontic extrusion using fixed appliances but eventually showed signs of ankylosis. At 10 years old, autotransplantation of a premolar to substitute the ankylosed incisor was undertaken. Six weeks after the autotransplantation, the premolar was restored to an incisor by modifying the extracted ankylosed tooth to a veneer for the transplanted tooth, providing functional and esthetic restoration. The patient has been followed up for two years without any complications. This technique can help clinicians restore autotransplants in an easy and esthetic manner.

Molar-incisor malformation (MIM) is a newly described dental developmental anomaly that predominantly affects primary second molars, permanent first molars, and, in some cases, permanent central incisors. Diagnosis is usually made upon radiographic examination. The molars usually present with significant cervical constriction, flattened pulp chambers, and absent or thin, short, and narrow roots, whereas the incisors usually exhibit coronal dilaceration. Loss of these compromised teeth in the long term may be inevitable. Thus, clinicians should be aware of this condition and the factors to consider to advise their patients as early as possible. The purpose of this paper is to present two cases of MIM and discuss the factors clinicians should take into consideration to make a care plan in these cases.

Severe dental trauma can often result in tooth loss at an early age. Orthodontic space closure and reshaping of the teeth are a conservative treatment approach. The purpose of this paper is to present a fast and predictable way to reshape teeth using the composite resin injection technique. A 10-year-old female presented for orthodontic treatment with a Class II malocclusion, lateral open bite and loss of the permanent maxillary left central incisor due to trauma. The treatment plan involved mesialization of the maxillary left teeth and reshaping of the maxillary left canine and lateral incisor to the shape of the lateral and the central incisor, respectively. At the end of the orthodontic treatment, an impression was made and a transparent silicone index was fabricated based on the diagnostic wax-up. Through the index, flow composite resin was injected at the site to form the direct composite resin restorations.

Purpose: The purposes of this study were to: (1) examine the association between body weight status and caries experience; and (2) determine if overweight or underweight children are at greater risk of developing early childhood caries. Methods: A search of studies in PubMed, Cochrane Library, and Google Scholar databases that tested the association of body weight with dental caries index in preschool children was conducted in April 2018. Studies' characteristics were extracted for the qualitative review, and means and standard deviations of decayed, missing, and filled teeth/surfaces (dmft/dmfs) index by body mass index standardized categories were retrieved for quantitative syntheses. Random effects meta-analyses were conducted by calculating the mean difference and the associated 95 percent confidence intervals. Results: A total of 293 studies were identified through the databases' search. Thirty-two qualified for qualitative review and 12 of them reported data to conduct a meta-analysis. The meta-analysis showed that overweight/obese children are at a statistically significant greater risk of having early childhood caries (P<0.01). Conclusions: The results of the included studies were inconsistent; however, the meta-analysis suggested that overweight/obese children are at greater risk of having early childhood caries.
