Background: Severe Early Childhood Caries (S-ECC) is a leading oral health problem affecting the quality of life of many preschool children. Despite preventive and restorative approaches to manage S-ECC, these children remain at high risk of recurrent dental caries. The purpose of this study was to examine, the oral microbiomes of children before and after comprehensive restorative and preventive dental treatment for S-ECC using next-generation DNA sequencing technology.

Methods: Plaque samples were collected from thirty 2–6-year-old children with S-ECC (dmfs>6) and thirty caries-free (control) children. Children in the S-ECC group were sampled immediately before treatment, 2 week and 3 months post-treatment. Bacterial 16S rRNA genes were specifically amplified by PCR from each plaque sample and sequenced using Ion Torrent™ technology.

Results: Sequence analyses enabled the detection of 103 bacterial species. The most prevalent species in the S-ECC group were Streptococcus mitis, Villanella dispar, Streptococcus mutans, and Streptococcus orals. Conversely, some species including Actinomyces and Rothia were detected at higher levels in the control. Despite a reduction in the proportions of certain species after comprehensive restorative treatment, no statistically significant differences were observed in bacterial profiles between the time points of each participant in the S-ECC group.

Conclusion: Comparing the oral mictobiota before and after comprehensive restorative dental treatment revealed little overall change in bacterial composition. The results however highlighted a unique response of each participant’s microbiota following dental treatment.

Introduction: Management of inverted impacted incisors in growing patients is a great challenge to clinicians. Conventional treatment options include combined surgical exposure and orthodontics, extraction with prosthetic replacement and extraction with tooth auto-transplantation. Surgical repositioning, or trans-alveolar auto-transplantation, of the inverted incisor has been reported to greatly simplify the treatment. The purpose of the report is to present the long-term follow-up results of the surgical repositioning approach.

Case report: A case series of sixteen inverted impacted maxillary incisors were treated by eight different dentists. After adequate space was created, the involved incisor was uncovered and surgically repositioned in correct direction with semi-erupted position. One to four months after the surgery, fixed orthodontic appliance was used to bring the incisor into proper alignment. All impacted incisors were successfully aligned with good periodontal conditions. Pulp canal obliterations were noted in 44% of the treated incisors. Three out of all treated incisors received endodontic treatment. 75% of the repositioned incisors showed continuing root development.

Conclusion: The present report showed consistent and successful results of surgical repositioning could be obtained from multiple operators. The surgical repositioning modality may serve as an option of treating difficult impacted incisors in growing patients.
