Microplastics (MP) and endocrine disruptors, such as bisphenol-A (BPA) have both become significant environmental concerns worldwide, although assessments in estuarine environments are still scarce. In this regard, Guanabara Bay is one of the most important Brazilian systems, displaying economic relevance, it has suffered increasing anthropogenic effects for decades. Thus, study aimed to assess...

Dust fallout can have diverse impacts ranging from major health problems to environmental concerns. It harbour disease-causing microorganisms and toxic heavy metals, it is therefore critical establish the microbial mineral compositions of dust in a particular site elucidate possible related implications for humans entire environment. In this study, samples were collected Arandis, town Erongo re...

BACKGROUND: The complete removal of root filling material is one the main goals non-surgical endodontic retreatment. Thus, development new techniques and instruments aiming to promote this task presents clinical significance. AIM: purpose study was assess amount residual canal materials (gutta-percha/sealer) after using two different retreatment systems ultrasonic tip. METHODS: Forty-five mandi...

Background and objective: Selecting a material with lower marginal gap is the key factor for successful dental prosthesis. With less of crown aggregation bacterial plaque at gingival margins, that result in periodontal diseases secondary caries could be limited. Methods: A mandibular right first molar sound tooth was prepared reference model according to preparations guideline heavy chamfer fin...

Aim: This study was conducted to throw light on the effect of papain –based gel (Papacarié) on microleakage and microshear bond strength of two esthetic restorative materials ; glass ionomer restoration (Fuji IX GP) and light cured hybrid composite resin (Valux Plus, 3M ESPE). Methods: Microleakage test: thirty primary molars with carious occlusal surfaces were randomly assigned into three grou...

Unrestrained utilization of plastic has reached an intemperate state, menacing environment and human lives. The preliminary focus this research was to investigate divulge the contemporary status microplastics (MPs) in commercialized open pan salts from Cox's Bazar Maheshkhali channels. A total 27 samples were obtained. analyzed for prevalence MPs by FTIR Raman spectroscopy (RS); prevailing amou...

ABSTRACT This study aims to report the occurrence of Heilipus draco in seeds Ocotea puberula, and describe main injuries caused effects on germination, as well parasitoid hymenopterans. To this end, fruits seven trees were selected, extreme south Atlantic Forest, Brazil. Fruit collection was carried out weekly middle third canopy, forming lots, from beginning fruit formation until total dehisce...

Objective: To evaluate the microleakage at junction between amalgam-composite resin restorations using different bonding systems. Material and Methods: In this in-vitro study, standard class II cavities were prepared on 40 human maxillary premolars. The axial gingival floor depths of 2 mm 1 below (cementoenamel junction), respectively. samples divided into 4 groups (n = 10). all groups, a layer...
