Association between Molecular Mechanisms and Tooth Eruption in Children with Obesity.

Different works have reported earlier permanent teething in obese/overweight children compared to control ones. In contrast, others have reported a delayed permanent teething in undernutrition/underweight children compared to control one. It has been reported that becoming overweight or suffering from obesity can increase gingival pro-inflammatory drive and can affect orthodontic treatment (among other complications). In this sense, little is known about the molecular mechanisms affecting dental eruption timing. Leptin and adiponectin are adipocytokines signaling molecules released in overweight and underweight conditions, respectively. These adipocytokines can modulate osteocyte, odontoblast, and cementoblast activity, even regulating dental lamina initiation. The present review focuses on the molecular approach wherein leptin and adiponectin act as modulators of Runt-related transcription factor 2 (Runx 2) gene regulating dental eruption timing.

Adjuvant Effect of Titanium Brushes in Peri-Implant Surgical Treatment: A Systematic Review.

BACKGROUND: the prognosis of peri-implant surgery can be affected by poor decontamination of the implant surface, which could be improved with the use of titanium brushes. The objectives of this systematic review were to evaluate the effectiveness of titanium brushes in the decontamination of the implant surface in terms of plaque index, probing depth, bleeding on probing and bone loss/gain; as well as its effectiveness according to the type of peri-implant bone defect. METHODS: an electronic search was carried out in the PubMed, Scopus, Cochrane and Embase databases, as well as a manual search. The search strategy included four keywords: "Peri-implantitis", "Periimplantitis", "Implant Surface Decontamination" and "Titanium Brush". Randomized controlled studies published in the last 10 years were included and systematic reviews, in vitro studies and animal studies were excluded. RESULTS: 142 references were found, from which only four articles met the inclusion criteria. All of the studies included in the present review reported beneficial results in terms of probing depth, gingival index and radiographic bone loss and gain after implant surface decontamination adjuvated by titanium brushes. CONCLUSIONS: titanium rotary brushes show improvements in the evolution and prognosis of peri-implant surgery, although more long-term studies are needed to draw more solid conclusions.

Type 1 diabetes mellitus and periodontal disease: Relationship to different clinical variables

Objective: This study is designed to evaluate the frequency of periodontal disease in a group of patients with type 1 diabetes mellitus and how this relates with diabetes metabolic control, duration of diabetes, and presence of diabetic complications.
Methods: A comparison was made of periodontal parameters (plaque index, bleeding index, pocket depth and attachment loss) in a group of diabetic patients (n=90) versus a group of non-diabetics (n=90). Logistic regression analysis was performed to evaluate relationship between periodontal parameters and degree of metabolic control, the duration of the disease, and the appearance of complications. Results: Diabetics had greater bleeding index (p<0.01), deeper periodontal pockets (p<0.01) and more periodontal attachment loss (p<0.01) than non-diabetics. Deficient metabolic control and presence of diabetic complication were associated with higher bleeding index and pocket depth (p≤0.02). Conclusions: Patients with type 1 diabetes appear to show increased periodontal disease susceptibility, particularly those with poorer metabolic control or with diabetic complications (AU)

Dental caries in type 1 diabetics: influence of systemic factors of the disease upon the development of dental caries.

OBJECTIVES: Diabetes mellitus is one of the most common chronic diseases in the general population. A study is made of the presence of caries in type 1 diabetic patients. The specific aim was to determine whether such patients present a greater incidence of dental caries than non-diabetic individuals. An evaluation was also made of the relationship of caries to salivary flow and to factors inherent to the disease such as the degree of metabolic control, the duration of diabetes, and the existence of chronic complications. STUDY DESIGN: The study comprised 90 type 1 diabetics between 18 and 50 years of age, and a group of non-diabetic controls matched for age and sex. Visual and tactile exploration of the dentition was carried out in all cases. Oral hygiene was rated based on the O'Leary plaque index, and basal (unstimulated) and stimulated salivary flow were evaluated in both groups. In the diabetic group, correlations were established with disease control based on the mean glycosylated hemoglobin (HbA1c) value corresponding to the two years prior to examination; evolution of the disease in years; and the existence of complications such as diabetic neuropathy or retinopathy. RESULTS: Under similar conditions of oral hygiene and salivary flow, the diabetic group showed a higher incidence of caries than the control group (p<0.05). Likewise, on specifically analyzing the diabetic group, metabolic control of the disease, the duration of diabetes, and the existence of complications of the disease exerted an influence upon the development of dental caries. CONCLUSIONS: Qualitative salivary studies are advised to better account for this increased incidence of caries in the diabetic population.

Caries dental en diabéticos tipo 1: Influencia de factores sistémicos de la enfermedad en la instauración de la caries dental / Dental caries in type 1 diabetics: influence of systemic factors of the disease upon the development of dental caries

Objetivos: La diabetes mellitus es una de las enfermedades crónicas más prevalentes en población general. Se presenta un estudio que pretende evaluar la presencia de caries en los pacientes diabéticos tipo 1. El objetivo específico era comprobar si había o no mayor incidencia de caries en diabéticos tipo 1 comparándolos con un grupo de individuos no diabéticos. También, se comprobó la relación con las tasas de flujo salival y con los factores propios de la enfermedad como el grado de control metabólico, el tiempo de evolución de la enfermedad y la existencia de complicaciones crónicas. Diseño del estudio: Se estudiaron 90 diabéticos tipo 1 de edades comprendidas entre los 18 y los 50 años de edad y un grupo de pacientes controles no diabéticos pareados por edad y sexo. Se realizó una exploración visual y táctil, en todos los dientes de los sujetos explorados. Se tuvo en cuenta el grado de la higiene oral mediante el índice de placa de O’Leary, y se estudiaron las tasas de saliva basal y estimulada en ambos grupos. En el grupo diabético se relaciono con el control de la enfermedad mediante la obtención de la media de la hemoglobina glicosilada (HbA1c) de los dos años previos a la exploración, así como la evolución de su enfermedad en años y la existencia de complicaciones como neuropatía diabética o retinopatía. Resultados: Bajo similares condiciones de higiene oral y de flujo salival, el grupo diabético resultó tener una incidencia de caries mayor que el grupo control (p<0.05). Asimismo, al estudiar específicamente al grupo diabético, ni el control metabólico de la enfermedad, ni la evolución de la enfermedad, ni la existencia de complicaciones de la diabetes tenían influencia en la instauración de caries dental. Conclusiones: Se sugiere que habría que estudiar factores cualitativos salivales que explicasen esta mayor incidencia de caries en los diabéticos

Manifestaciones orales y manejo odontológico durante la menopausia / Oral manifestations and dental treatment in menopause

La menopausia es un proceso fisiológico que acontece en la quinta década de la mujer y en el que tiene lugar el cese permanente de la menstruación. Este proceso tiene como base unos cambios hormonales que tendrán como consecuencia una serie de manifestaciones clínicas de tipo general que han cobrado especial importancia por el aumento de la esperanza de vida en la mujer, lo que significa que la mayoría de estas mujeres padecerán dichos síntomas durante la última tercera parte de su vida. Sin embargo, no son sólo los síntomas generales (sofocos y alteraciones psicológicas) los que se manifiestan en la mujer menopaúsica, sino que también se producen síntomas a nivel oral. Así pues, existe un aumento en la incidencia de xerostomía, afecciones como el liquen plano, el penfigoide benigno, el síndrome de Sjögren, el conocido síndrome de ardor bucal y la discutida prevalencia de enfermedades periodontales. El manejo odontológico de estas pacientes presenta ciertas peculiaridades que deben ser consideradas, tales como el empleo de estimulantes de la secreción salival o de sustitutivos de la saliva en el caso de la hiposialía. No obstante, una correcta prevención, con un buen control de placa bacteriana, disminuirá los riesgos de aparición de muchas de las infecciones a nivel oral (AU)
