Preparation Techniques

Acid-etching of enamel surfaces has been performed routinely to bond adhesive resin materials to sound dental enamel as a caries-preventive measure. The effect of fluoride pretreatment on acid-etching of enamel has been reported to produce inconsistent and unsatisfactory etching patterns. The failure to obtain an adequate etch has been postulated to be due to fluoride precipitation products deposited on the enamel surface. The purpose of this study was to evaluate the effects of fluoride pretreatment on acid-etching of carieslike lesions of human dental enamel.Caries-like lesions of enamel were created in vitro on human molar and premolar teeth. The teeth were divided into two fluoride treatment groups. The specimens were exposed for 4 minutes to either a 2% Sodium Fluoride (NaF) solution or a 10% Stannous Fluoride (SnF2) solution. The specimens were then washed in deionized-distilled water. Each tooth was sectioned into four test regions. This was carried out to compare the effects of various time exposures (0 to 2 minutes) and differing concentrations (10 to 60% w/w) of phosphoric acid (H3PO4) on etching of caries-like lesions. Standard preparation techniques for SEM were performed on the specimens.

Topical Fluoride

Although fluoride levels become elevated in sound enamel following a topical fluoride treatment, the caries-preventive effect of fluoride is thought to be due primarily to the role of fluoride in remineralization of clinically undetectable enamel lesions and hypomineralized enamel. During lesion formation, redistribution of fluoride from the enamel surface to the subsurface demineralized enamel occurs. This results in a surface zone with a relatively low fluoride content. In order to maintain an intact surface zone over a carious lesion, it may be necessary to replenish the fluoride levels with an exogenous fluoride source. By acid-etching the lesion surface, a more reactive surface is made available for fluoride interaction. In addition, porosities and etching patterns may be created, allowing for bonding of a caries-resistant resin material to the lesion surface. The purpose of this study was to determine the integrity of the caries-like lesion surface following acid-etching and subsequent stannous fluoride treatment (SnF2).

Self Harm

Abstract. Background: Indigenous Australians experience a suicide rate over twice that of the general population. With nonfatal deliberate self-harm (DSH) being the single most important risk factor for suicide, characterizing the incidence and repetition of DSH in this population is essential. Aims: To investigate the incidence and repetition of DSH in three remote Indigenous communities in Far North Queensland, Australia. Method: DSH presentation data at a primary health-care center in each community were analyzed over a 6-year period from January 1, 2006 to December 31, 2011. Results: A DSH presentation rate of 1,638 per 100,000 population was found within the communities. Rates were higher in age groups 15–24 and 25–34, varied between communities, and were not significantly different between genders; 60% of DSH repetitions occurred within 6 months of an earlier episode. Of the 227 DSH presentations, 32% involved hanging. Limitations: This study was based on a subset of a larger dataset not specifically designed for DSH data collection and assesses the subset of the communities that presented to the primary health-care centers. Conclusion: A dedicated DSH monitoring study is required to provide a better understanding of DSH in these communities and to inform early intervention strategies.

Care Problems

The rural Kumiai community of San Antonio Necua is one of the few remaining indigenous communities in Baja California, Mexico. Necuan health and health care problems are best understood through a consideration of the effects of colonialism and marginalization on indigenous groups in northern Baja California as well as a tradition of medical pluralism in Mexico. The lack of traditional healers and biomedical providers in the community, high rates of preventable or manageable illnesses, and a blend of biomedical, folk mestizo, and traditional indigenous beliefs about health and illness reflect current conditions of rural poverty and economic isolation. Descriptions of health and health care problems are based on ethnographic fieldwork among the Kumiai, their Paipai relatives, and their primary nongovernmental aid organization.

This study is related to the practice of slavery happened in indigenous communities in North Borneo since under the rule of the Sultanate of Sulu and Brunei. The aim of this study to see how slavery is considered as a unique practice and the slave role in daily life, including the type of slaves and relationship between the slave and their owners. This study will use information about slavery in North Borneo which are available from various sources such as diary, Official records of British North Borneo Chartered Company (BNBCC), Reports, News paper, Microfilm, books and articles. Slavery in North Borneo basically influenced by the role of datu’s and pengiran of the Sulu Sultanate and Brunei which sparked demand for slaves. This causes a form of slavery that occurred in the indigenous tribes such as Suluk, Bajau, Iranun, Dusun and Murut. The practice of slavery grow rapidly along with pirate activities which are intertwined with the slave trading in the Borneo sea. However, before settling by James Brooke in Sarawak and BNBCC in North Borneo, the abolition of slavery activities was implemented.

Kajian ini bertujuan untuk melihat bagaimana amalan perhambaan dianggap sebagai sebuah amalan yang unik dan peranan golongan hamba tersebut dalam kehidupan harian termasuklah jenis hamba dan bentuk hubungan di antara hamba itu sendiri dan pemilik hamba. Kajian ini akan menggunakan maklumat mengenai perhambaan di Borneo Utara yang boleh didapati daripada pelbagai sumber seperti catatan diari pegawai British, rekod-rekod Syarikat Berpiagam Borneo Utara British (SBBUB), laporan, akhbar, Mikrofilem, Buku-buku dan Artikel yang telah dihasilkan oleh sarjana awal. Perhambaan di Borneo Utara pada dasarnya banyak dipengaruhi oleh peranan pembesar daripada Kesultanan Sulu dan Brunei yang mencetuskan permintaan terhadap hamba. Hal tersebut menyebabkan wujud perhambaan yang berlaku dalam suku peribumi seperti Suluk, Bajau, Iranun, Dusun dan Murut. Amalan ini berkembang pesat bersama dengan aktiviti perlanunan yang saling berkait dengan perdagangan hamba di sekitar perairan Borneo. Namun demikian, menjelang pertapakan James Brooke di Sarawak serta SBBUB di Borneo Utara, penghapusan aktiviti perhambaan ini telah dijalankan.

Meteorological Phenomenon

This article explores how the Nahua of late Postclassic Mesoamerica (1200–1521 CE) created living and material embodiments of their wind god constructed on the basis of sensory experiences that shaped their conception of this divinized meteorological phenomenon. In this process, they employed chromatic and design devices, based on a wide range of natural elements, to add several layers of meaning to the human, painted, and sculpted supports dressed in the god’s insignia. Through a comparative examination of pre-Columbian visual production—especially codices and sculptures—historical sources mainly written in Nahuatl during the viceregal period, and ethnographic data on indigenous communities in modern Mexico, my analysis targets the body paint and shell jewelry of the anthropomorphic “images” of the wind god, along with the Feathered Serpent and the monkey-inspired embodiments of the deity. This study identifies the centrality of other human senses beyond sight in the conception of the wind god and the making of its earthly manifestations. Constructing these deity “images” was tantamount to creating the wind because they were intended to be visual replicas of the wind’s natural behavior. At the same time, they referred to the identity and agency of the wind god in myths and rituals.
