7 Dec

In recent years there is a concern increasingly higher on the harmful effects of smoking in terms of an increase in the frequency of smokers in the population. Numerous studies have shown the link between various diseases of the mouth and smoking, there is in this sense a concern for public awareness on the harmful effects of smoking.

Increasingly more evidence indicating smoking as a major risk factor for periodontal disease (disease of the supporting tissues of the teeth). Smoking affects the prevalence, extent and severity of these diseases. Various studies in America and Europe show a prevalence of periodontitis 1.5 to 7.3 times higher in smokers compared to non-smokers. The number of years the person has smoked is a significant factor in tooth loss, coronal caries severity and periodontal disease.

The mechanisms by which smoking acts periodontal disease are not fully understood. It has been shown that there is a qualitative change of the microorganisms involved in the production of periodontal disease in smokers. Smoking also produces a decrease in the local immune response by decreasing the number and impaired neutrophil function (defensecells) and a decrease in the production of antibodies. It has been shown an increase of tissue destructive enzymes in the conditions of local microcirculation damage (decrease blood supply and nutrients caused by smoking).

Of great interest is the involvement of smoking in cancers in oral- maxillofacial area. Oral cancer has a frequency of 5% of all cancers and the frequency is increasing.

Studies by various authors regarding the etiology of oral cancer indicates that tobacco consumed in various forms plays an important role in this respect. 90 % of patients with oral cancer use tobacco (cigarettes, pipe,and cigar, chewing tobacco). Smoking cigarettes seems to be more harmful than smoking a cigar or pipe. Various studies show that men who smoke are at risk 30 times greater than nonsmokers in triggering oral malignant tumors , while former smokers shows a nine times greater risk than non-smokers . Talk to your dentist in Puerto Vallarta about the risks of smoking according to your age and gender group.

An increased incidence of oral cancer in women has been demonstrated in recent years and a decrease in men given that the percentage of men who quit smoking is higher than that of women. Studies show that about 90 % of deaths from cancer of the oropharynx in males can be attributed to smoking (in women the percentage is 61 %).

As with periodontal disease mechanisms of action are not fully known, which makes tobacco to be considered a risk factor and not a causal factor. Thus, there is a well-established relationship between lip cancer and smoking pipe.

It would seem that tobacco cause damage in the cells of the oral and oral-pharyngeal mucosa causing rapid growth of abnormal cells in the tissue repair process. Clinical & Experimental Research has shown involvement in oral cancers of chemicals that cause changes in cellular DNA by producing mutant cells. These substances are the results from burning tobacco tar and rolling papers. Approximately 12 substances with carcinogenic effect have been identified. The risk of oral cancer is mainly related to the number of cigarettes consumed per day and the period of time. A former smoker’s risk of developing oral cancer field becomes equal to that of a nonsmoker only after 10 years of non-smoking.
