Effects of radiation therapy on the morphology and composition of root dentin and cementum in primary teeth.

The aim of this study was to evaluate, in vitro, the effects of radiation therapy on the morphology and chemical composition of root dentin and cementum of primary teeth. Roots of human primary teeth were exposed to varying doses of irradiation using a linear accelerator: Group 1 = irradiation dose of up to 30 Gy (n= 6); Group 2 = irradiation dose of up to 42 Gy (n= 6); and Group 3 = irradiation dose of up to 54 Gy (n= 6). Non-irradiated human deciduous teeth were used as controls (n= 3).

Effect of low-level laser stimulation of acupuncture points in pediatric dentistry: a systematic review.

The biomodulatory potential of low-level laser therapy (LLLT) has prompted investigations of different outcomes in health. One line of research is the stimulation of acupuncture points for the relief of different signs and symptoms related to the stomatognathic system. In dentistry, some studies in pediatric dentistry have demonstrated the benefit of LLLT therapies in the management of dental anxiety in children.

VEGF and FGF-2 Released In Palatal Suture after Rapid Maxillary Expansion (RME).

Vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (FGF-2) have the ability to increase vascular proliferation and permeability. The aim of this study was to quantify the release of two diffusible angiogenic growth factors (VEGF and FGF-2) after rapid maxillary expansion (RME). Thirty animals were randomly assigned to two groups.

Oral rehabilitation in a patient with Jeune syndrome presenting with multiple teeth agenesis.

Jeune syndrome (JS) is a rare disease, with systemic manifestations, such as renal and hepatic insufficiency, retinal pigmentation, and respiratory insufficiency. Etiological factors have not been completely elucidated, but the molecular biology has contributed to the diagnosis and understanding of JS with DNA sequencing, showing the association among polymorphisms in different genes DYNC2H1 (MIM 603297) and TCTEX1D2 (MIM617353), which are the main genes associated with JS. There are a few reports on buccal findings in these patients; here, we present dental anomalies and clinical oral findings in a patient with JS, focusing on a multidisciplinary approach for rehabilitation.

Oral Rehabilitation of a Child with Hypohidrotic Ectodermal Dysplasia.

Hypohidrotic ectodermal dysplasia (HED) is a genetic condition characterized by abnormal development of two or more structures of the ectoderm, such as skin, hair, nails, teeth, or sweat glands. The most common dental anomalies are oligodontia and anodontia but taurodontism has also been described. These patients present a decrease of alveolar bone volume and alveolar ridge tapering due to congenitally missing teeth.
