DPPSCs, isolated from human third molars, are the most relevant cell model to draw conclusions about the role of biomaterials on dental tissue regeneration. Cytotoxicity, alkaline phosphatase (ALP) activity, and calcium deposition analysis were evaluated at different differentiation time points.

Implant-supported fixed prostheses in a Patient with Osteogenesis Imperfecta: A 4-year follow-up.

Osteogenesis Imperfecta (OI) is a rare autosomal dominant connective tissue disorder in wich, the bone quality and density is affected. OI includes some metabolic disorders and have a wide range of clinical presentations. In Osteogenesis Imperfecta bone has a very low density and it is a disorder currently treated with bisphosphonates.

Management of Ankyloglossia and Breastfeeding Difficulties in the Newborn: Breastfeeding Sessions, Myofunctional Therapy, and Frenotomy.

The problems of suction in newborns give rise to multiple consequences for both the mother and the newborn. The objective of this paper is to present a case of ankyloglossia ("tongue-tie") and the suction problems that were treated by a multidisciplinary team. The subject is a 17-day-old male patient, with ankyloglossia and suction problems during breastfeeding (pain in the breastfeeding mother, poor weight gain, and long breastfeeds).

Multidisciplinary management of ankyloglossia in childhood. Treatment of 101 cases. A protocol.

Background: Partial ankyloglossia is a limitation which restricts the possibility of protrusion and elevation of the tip of the tongue due to the shortness of either the lingual frenulum or the genioglossus muscles or both. The principal objective of this paper is to present our protocol of action for the treatment of ankyloglossia. The specific objectives are to study patients with ankyloglossia treated by the Service of Maxillofacial Surgery and the Service of Speech Therapy of our pediatric Hospital, describe the diagnostic procedures, the pre-surgical intervention, the surgical technique undertaken and the post-surgical rehabilitation taking into account the level of collaboration of the patients, and finally, describe the surgical complications and the referral of patients.

Gingival bleeding of a high-flow mandibular arteriovenous malformation in a child with 8-year follow-up.

Intraosseous arteriovenous malformations (AVMs) in the head and neck region are uncommon. There are several types and they can have a wide range of clinical presentations. Depending on the blood flow through the AVM, the treatment may be challenging for the attending team and may lead to life-threatening hemorrhages.

Effect of implant design in immediate loading. A randomized, controlled, split-mouth, prospective clinical trial.

Objectives: The aim of this study was to evaluate the effect of two different designs, tapered vs cylindrical, on the primary stability of implants placed with an immediate loading protocol in edentulous mandibles to support fixed prostheses within occlusal contacts during the first 48 h.

Material And Methods: Tapered and cylindrical implants were placed in a split-mouth study using the same implant protocol in ten patients with edentulous jaws. A total of 20 tapered implants (test group) and 20 cylindrical implants (control group) were placed.

Dental pulp of the third molar: a new source of pluripotent-like stem cells.

Dental pulp is particularly interesting in regenerative medicine because of the accessibility and differentiation potential of the tissue. Dental pulp has an early developmental origin with multi-lineage differentiation potential as a result of its development during childhood and adolescence. However, no study has previously identified the presence of stem cell populations with embryonic-like phenotypes in human dental pulp from the third molar.

Thermal changes and drill wear in bovine bone during implant site preparation. A comparative in vitro study: twisted stainless steel and ceramic drills.
