The aims of the present study were to provide nationally representative data on fruit and vegetable consumption in Vietnam, and to assess the accuracy of the reported numbers of ‘standard servings’ consumed. Data analysed were from a multi-stage stratified cluster survey of 14 706 participants (46·5 % males, response proportion 64·1 %) aged 25−64 years in Vietnam. Measurements were made in accordance with the WHO STEPwise approach to surveillance of non-communicable diseases (STEPS) protocols. Approximately 80 % of Vietnamese people reported having less than five servings of fruit and vegetables daily in a typical week. Fruit and vegetable intake reported in ‘standard serving’ sizes was positively correlated with levels of education completed and household income (P<0·001 for trend). The correlations between summary values for each province reflect some known demographic, geographical and climatic characteristics of the country. For example, provinces at higher latitude had higher mean servings of vegetables (r 0·90), and provinces with higher proportions of urban population had higher mean servings of fruit (r 0·40). In conclusion, about eight in ten Vietnamese people aged 25–64 years did not meet WHO recommendations for daily consumption of at least five servings of fruit and vegetables. On the basis of the consistency of the data collected with other estimates and with physical and demographic characteristics of the country, the WHO STEPS instrument has construct validity for measuring fruit and vegetable intake, but with two issues identified. The issues were seasonal variation in reporting and a limitation on the usefulness of the information for associative analyses.

This article presents solutions to problems posed by missing teeth in the anterior sector of the arch by synthesizing three groups of parameters, those related to patients, those related to dentists, and those related to the orthodontist.

But the patient, or the parents of patients who are young children, in consultation with the treatment professionals, must make the final decision.

In general, the smile that orthodontists try to create at the end of treatment satisfies objective functional criteria as well as subjective esthetic criteria.

It’s obvious that in today’s society, a smile plays an important role in nonverbal communication: restoring or enhancing this smile is, in fact, the main reason patients consult their orthodontists.

After reviewing the literature, we were able to identify various factors involved in the perception of a smile and to underscore the esthetic connection between the smile and the face.

Is there a relationship between the smile and facial harmony?

What are the objective criteria that allow us to discern whether a smile is pleasant or not?

Our study confirmed that the esthetics of the face correlates with the perception of the smile and that the factors discussed in the literature pertaining to this correlation are valid.

However, the study has also made it possible to clarify the respective influence of various factors as they relate to a pleasant smile, an unattractive smile or an unsightly smile. Therefore, our study has shown that objective functional criteria are involved in the entirely subjective esthetic realm of a smile.

The objective of this work is to study the static and dynamic occlusion of dentitions in a Class III molar relationship to determine what might be the indications for treatment that would leave buccal segments in this position, and to evaluate the occlusal adaptions that would be needed to make it functionally acceptable.

The historiography of the Sanusiyya, if one can apply such a term to the literary crop of roughly a century dealing with this North African tarīqa (pl. turuq, Sufi brotherhood), falls into three distinct categories. The earliest writings appeared in the 1880s, thirty years after the tariqa had taken root in Cyrenaica (then the Ottoman province of Benghazi). The works of French authors such as Charmes, Rinn, Duveyrier, Le Chatelier, and co-authors Depont and Coppolani were all marked by the concerns of the French colonial and protectorate authorities in Algeria and Tunisia. According to Duveyrier, a Saharan explorer of repute and the crudest exponent of this group's views, not only were the Sanusis a band of fanatics given to murdering innocent missionaries and explorers, but they were also in the vanguard of the turuq inspired by the Pan-Islamic rhetoric of the Ottoman sultan and aligned against French colonialism in Muslim North Africa. Only this combination of factors could account for the pervasive and determined resistance to French policies in the region. Along with the Sanusiyya, Duveyrier singled out for attack a North African sheikh and confidant of the Ottoman sultan, Muhammad Zafir al-Madani. Charmes, Rinn, Le Chatelier, and Depont and Coppolani, while less vitriolic in their tone, certainly had the same general approach. The analysis of this “Algerian school” was dismissed at the turn of the century by two eminent Orientalists, Christiaan Snouck Hugronje and Carl Heinrich Becker.3 A generation later, European fears of the turuq diminished in the wake of World War I, as new ideologies and forces came to dominate a transformed Pan-Islamism. This notwithstanding, some of the suppositions of the early French authors were adopted by later scholars and have since been quoted and requoted.
