RESUMO
The aim of the SmoCar (Smoking in the Caribbean) study was to estimate the prevalence of smoking and the disparities in the smoking practices of three regions in the Caribbean: Jamaica, Dominican Republic, and Puerto Rico. The secondary objective was to assess the prevalence and severity of gingivitis in relation to the smoking practices. The study population comprised 1,847 (weighted N = 1,830) individuals (18 years and older) who were volunteer participants from the capitals of Jamaica, Dominican Republic, and Puerto Rico. A structured interview was used to assess the participants' smoking behaviors. The gingival index was used to determine the extent of gingival inflammation. Polytomous regression was used to estimate the adjusted odds ratios (aORs) for smoking status (current, past, or never), according to risk factors (sex, age-group, education, marital status, tooth-brushing frequency, and city of residence). Logistic regression models were used to assess the associations between different smoking status variables and mild to moderate/severe gingivitis. The majority of the participants were never-smokers, with current smokers being found most commonly in Kingston (33.22%), followed by San Juan (12.76%) and Santo Domingo (8.8%). Both current (aOR = 2.22, 95% confidence interval [1.45, 3.40]) and past (aOR = 1.87, 95% confidence interval [1.19, 2.93]) smoking (vs. never smoking) was strongly associated with severe gingivitis. Smoking was the most prevalent in Jamaicans and the least prevalent in Dominicans. The study population of current smokers was found to have a fourfold increased risk of severe gingivitis and a twofold increased risk of moderate gingivitis.

Traditionally, a healthy mouth is a good indicator of good general health. Poor oral hygiene reflects the health of the oral cavity and is a risk factor for overall health. Although oral diseases like dental decay and periodontitis are prevalent, awareness of oral diseases is still limited. Oral disorders include a wide range of diseases that may not be confined to the oral anatomical structures but may be manifestations of systemic diseases. Identification of the risk factors of dental and oral diseases, including socio-economic determinants, plays a major role in the type of oral health care, and in the promotion of dental health awareness. This article reviews oral diseases in the Caribbean and aims to raise awareness of this subject while suggesting a research agenda for the region.
RESUMO
AIM: Human papillomavirus (HPV) has been reported to be associated with oral and oropharyngeal cancer. However, little information is available about the epidemiology of oral HPV infection in Jamaica. The purpose of the present study was to assess the prevalence of oral HPV strains using the oral rinse method in HIV and non-HIV Jamaican patients, as well as to determine the association of HPV with sexual practices, smoking, and alcohol use. METHODS: A cross-sectional study was conducted on patients attending The University of the West Indies Mona Dental Polyclinic and the Centre for HIV/AIDS Research and Education Services. Salivary samples were tested through molecular analysis for 37 HPV genotypes using the linear array HPV genotyping test. A survey questionnaire was used to obtain demographic details, smoking history, alcohol practice, sexual practice, and history of HPV testing. RESULTS: The HPV prevalence was 8.65% in 18-64 y olds (N = 104), with a slight female predilection (55%). No high-risk HPV types were found. HPV-84 was the most common type in both HIV and non-HIV patients; 66.7% of HPV-positive participants reported that they had six or more lifetime sexual partners. CONCLUSION: The prevalence of oral HPV was similar to that in other countries. No statistically-significant relationship was observed between the prevalence of HPV and either the number of sexual partners, smoking, or alcohol history. A nationwide study on oral HPV detection might be helpful in developing a HPV vaccination policy in Jamaica.

In the human biological system, the individual cells divide and form tissues and organs. These tissues are hetero-cellular. Basically any tissue consists of an epithelium and the connective tissue. The latter contains mainly mesenchymally-derived tissues with a diversified cell population. The cell continues to grow and differentiate in a pre-programmed manner using a messenger system. The epithelium and the mesenchymal portion of each tissue have two different origins and perform specific functions, but there is a well-defined interaction mechanism, which mediates between them. Epithelial mesenchymal interactions (EMIs) are part of this mechanism, which can be regarded as a biological conversation between epithelial and mesenchymal cell populations involved in the cellular differentiation of one or both cell populations. EMIs represent a process that is essential for cell growth, cell differentiation and cell multiplication. EMIs are associated with normal physiological processes in the oral cavity, such as odontogenesis, dentino-enamel junction formation, salivary gland development, palatogenesis, and also pathological processes, such as oral cancer. This paper focuses the role EMIs in odontogenesis, salivary gland development, palatogenesis and oral cancer.
