An elevated number of failures were observed due to recurrent caries, highlighting the need for professionals to work with a health-promoting approach. The high variation on failure rate among the materials can be due to children's behavior during the procedure, which demands short dental appointments and a controlled environment.

Mental and oral health are among the main disabilities worldwide. This article helps to understand more about the relationship between both conditions, highlighting the importance for both clinicians and policy makers of considering individual's psychological status in management of oral health.

Objectives The purpose of this systematic review was to incorporate the information published on metastatic lesions in the in the oral and maxillofacial region into a comprehensive analysis of their demographic, clinical, and imaginological features and survival rate. Materials and methods An electronic search was undertaken in the subsequent databases: PubMed, Web of Science, Scopus, EMBASE, and LILACS. All papers included were case reports or case series. Absolute and relative frequencies were obtained by descriptive analysis. Overall survival was defined by the Kaplan–Meier method. Results This systematic review identified 217 studies from 33 countries, comprising 348 cases. Male individuals were more affected (n = 199/57.68%) in the 5th to 7th decades of life. The most usual primary site was the lung in men (n = 49/14.08%) and the breast in women (n = 40/11.49%). Jawbones were affected in 183 cases (53.19%), with the posterior mandible (n = 96/66.66%) representing the preferred site. In soft tissues, the gingiva (n = 80/23.25%) was more affected. Clinical presentation was a nodular mass with or without ulceration (n = 280/85.89%). Imaginological examinations revealed radiolucent/hypodense lesions (n = 115/59.28%). The mean survival time was eight months. Conclusion Despite the rare occurrence of metastatic lesions in the oral and maxillofacial region, the current systematic review offers substantial data that could assist clinicians and surgeons.

Positive association between periodontitis and halitosis was found in pooled results of population-based observational studies. However, this evidence is derived from cross-sectional studies.
