Background The Internet is a growing source of knowledge and can provide information about oral health. This ecological study aimed to characterize the interests of Google users on toothpaste in different countries. Methods This longitudinal retrospective study analyzed the toothpaste-related interest of Google users from ten distinct countries between January 2004 and December 2020. The monthly variation in Relative Search Volume (RSV) and the main related queries were determined using Google Trends. Autoregressive Integrated Moving Average (ARIMA) forecasting models were built to establish the predictive RSV values for mouthwash for an additional 12 months. Auto-correlation plots and a general additive model (GAM) were used to diagnose trends and seasonality in RSV curves. Additionally, the influence of social isolation during the COVID-19 pandemics was analyzed. Results Although not detected by ACF and PACF analyses, the heuristic analysis showed an increase in the interest in toothpaste-related information in all countries, with a stable trend observed in the 12-month forecasts, except for the increases in the United Kingdom and South Africa. Also, GAM analyses demonstrated a non-significant monthly or quarterly seasonal influence on data. In addition, the social isolation of the COVID-19 pandemic did not influence the online information-seeking behavior of Google Search users linked to this topic. Discussion The heuristic analysis of the time series indicated an increase in the interest of Internet users in toothpaste between January 2004 and December 2020. This increase may reflect the population's growing autonomy for solving their own health problems. The Internet seems to be the most popular source of information. As such, this information may enable the implementation of specific public oral health policies and oral-care communications based on the population´s needs. Along these lines, information monitoring and improvements in oral health literacy may contribute to the reduction of currently existing social and economic barriers. Conclusion The interest of Google Search users in information about toothpaste increased in all ten countries. These trends were not influenced by the outbreak of the COVID-19 pandemic in most countries.

Objetivo: O objetivo desta revisão bibliográfica foi descrever estudos que buscaram analisar a efetividade da tomografia computadorizada cone beam (TCFC) na análise da densidade mineral óssea (DMO) da região maxilo-mandibular. Foram incluídos nesta revisão artigos referentes ao uso da TCFC na análise da DMO da região maxilo-mandibular de 2009 até 2020, publicados nas base de dados: PUBMED, EMBASE e Scopus.Resultados: Foram selecionados 17 artigos que investigaram o uso da TCFC no estudo da DMO maxilo-mandibular. Muitos pesquisadores utilizaram-se da micro-tomografia, tomografia computadorizada multislice e análise histomorfométrica para realizar comparações com a TCFC.Conclusões: As evidências bibliográficas sugerem que a TCFC, tanto através dos seus valores de escala de cinza quanto pelos seus parâmetros 3D estruturais, se apresenta como um método de relevância clínica, confiável e fácil, de análise proporcional da densidade óssea da região maxilomandibular.

BACKGROUND This study aimed to compare the periodontal status of liver transplant candidates (LTCs) with healthy controls. METHODS Fifty liver transplant candidates (LTC group) and fifty patients without liver disease (control group) underwent a complete periodontal examination. The groups were matched according to sex, age, and smoking status. A structured questionnaire was applied to record demographic data, systemic health, and information related to liver disease. Full-mouth complete periodontal examination of six sites per tooth was performed: gingival recession (GR), probing depth (PD), attachment loss (AL), bleeding on probing (BOP), and visible plaque index (VPI). The groups were compared in regard to periodontal clinical variables. RESULTS Patients with cirrhosis had greater prevalence of periodontitis than healthy controls (P

Objetivos: Determinar la prevalencia de caries dental en los niños del centro de educación básica especial Helen Keller situado en el Callao, Perú durante el 2015. Material y Métodos: Estudio observacional, transversal sobre los datos de 30 niños del centro de educación básica especial Helen Keller. Información recogida por alumnos de la Facultad de Estomatología de la Universidad Peruana Cayetano Heredia (UPCH), en el centro educativo durante el año 2015. Se analizaron las características de los niños (edad, sexo, y diagnóstico sistémico). Para caries dental se utilizó el índice CPOD/ceod y el índice CPOS/ceos. Resultados: El 90% (n=27) de los escolares presentó caries dental. El retardo mental fue la condición más prevalente (43,3%, n=13). Se encontró un índice de CPOD de 2,9 (DE 3,8) y en dientes deciduos (ceod) de 6,0 (DE 4,0). Conclusiones: Existe una alta prevalencia de caries dental en los niños del centro de educación básica especial Helen Keller Callao, Perú en el año 2015. Objectives: Determine dental caries prevalence of children from a basic educational center for special needs, Helen Keller school situated at Callao, Perú during 2015. Material and Methods: Cross-sectional study on a sample of 30 children from the basic educational center for special needs, Helen Keller school. The data was collected from Universidad Peruana Cayetano Heredia (UPCH) during 2015 at mentioned school. Children characteristics were analyzed (age, sex, systemic diagnosis) in frequencies, and dental caries prevalence. We analyzed dental caries per each tooth (DMFT/dmft index) and each surface (DFMS/dmfs index). Results: 90% (n=27) of scholars had dental caries. Mental retardation, was the most common condition (43.3%, n=13). We found a DMFT index of 2.0 (SD 3.8) and in deciduous teeth (dmft index) of 6.0 (SD 4.0). Conclusions: There is a considerable proportion of children that have dental caries in Basic educational center for special needs Helen Keller, Callao, Perú during 2015.
