Periodontal health status and smoking among young adults

Anxiety in periodontally healthy, stage III/IV periodontitis with and without smoking: a cross-sectional study

BACKGROUND

Psychological stress and smoking have been known as pertinent risk factors associated with various inflammatory diseases like periodontal disease. So, the aim of this study was to evaluate and correlate anxiety in Periodontally healthy, Stage III/IV Periodontitis patients with and without smoking.

METHODS

120 participants included in the study were divided equally into four groups of healthy non-smokers (Group I), healthy smokers (Group II), non-smokers with untreated Stage III or IV periodontitis (Group III) and smokers with untreated Stage III or IV periodontitis (Group IV). The anxiety levels of the patients were assessed using the Zung's self-rating anxiety scale. Socioeconomic status, smoking exposure through a questionnaire and the clinical parameters Probing pocket depth (PPD), Clinical attachment levels (CAL), Gingival index (GI) and Plaque index (PI) were recorded.

RESULTS

The clinical periodontal parameters were compared within and across the groups at the four different anxiety levels and depicted a significant increase with the increase in the anxiety levels of the patients. The correlation of CAL with the anxiety score in Group III and Group IV was high positive (r = 0.926 and 0.823) and highly significant. (p-value < 0.0001 respectively). Also, a strong positive association was seen between duration, frequency of smoking and anxiety scores. (r = 0.824 and 0.853 respectively).

CONCLUSION

The anxiety scores showed a positive correlation with PPD and CAL in Group III and IV and it was high positive in smokers.

Epidemiological methods used in the periodontal health research in military personnel: a systematic review

INTRODUCTION

Periodontal disease is a prevalent pathology in military personnel worldwide. The objective is to analyse the methodological features of periodontal health research performed in military personnel in their home countries.

METHODS

A PRISMA systematic review of literature was carried out in PubMed, EMBASE and Web of Science databases on military periodontal health studies. Study design type, language, publication date, year, country, size and sample selection, age, sex, military, diagnostic procedure, examiners, periodontal, gingival and oral hygiene index were extracted.

RESULTS

Eighty-eight out of 5355 studies found were selected, published between 1921 and 2020, with samples ranging from 52 to 16 869 individuals, generally not randomised, and consisting mainly of men with a mean age of 25 years. Predominant studies were cross-sectional descriptive studies, carried out in the Army, on American military personnel, and in the English language. Most of the studies used the WHO periodontal probe handled by two or more examiners. The Löe and Silness gingival index and the Silness and Löe plaque index were the most used indexes to assess gingival condition and oral hygiene, respectively. Community Periodontal Index of Treatment Needs was the most widely used periodontal index.

CONCLUSIONS

Research on periodontal health carried out in military populations from the 1920s to the present has been performed from an almost exclusively descriptive approach. Issues such as the characteristics and representativeness of the samples, the epidemiological design and the different gingival-periodontal indexes used may limit the comparability of the study results.

Cigarette smoking and its consequences on periodontal health in teenagers: a cross-sectional study

OBJECTIVES

Smoking has been extensively investigated as a risk factor for periodontal disease and many studies have confirmed it. The aim of this study was to show data from Croatia on periodontal health among high school students, with the focus on association of tobacco use and oral hygiene habits, and the periodontal parameters.

METHODS

Pocket probing depth (PPD), bleeding on probing, supragingival calculus, and oral hygiene habits were recorded for each examinee out of 517 high school students. PPD was measured at 4 interproximal sites on all first molars and central incisors (index teeth).

RESULTS

There were 34.6% smokers among subjects, who started smoking on average at the age of 14. More than half of the smokers (55.3%) smoked 1-10 cigarettes per day and intensity of smoking increased with age. PPD was significantly greater (p = 0.012) in smokers (1.69 mm) than in non-smokers (1.59 mm). In non-smoking subjects, increased values of PPD were in direct proportion to the reduced frequency of brushing, while there was no difference in smokers. The number of cigarettes smoked and duration of smoking had a great influence on PPD. Smokers had on average more teeth with supragingival calculus than non-smokers, while non-smokers had more bleeding on probing, and the difference was statistically significant (p < 0.001).

CONCLUSIONS

This study indicated that cigarette smoking was associated with decreased periodontal health even in this young population. Irregular oral hygiene was associated with decreased periodontal health only in non-smokers. Therefore, it should be important to inform young smokers about the negative effects of cigarette smoking on periodontal health, to provide consultations and reinforce smoking prevention measures.

Assessment of the correlations between nicotine dependence, exhaled carbon monoxide levels and oral hygiene status: an observational study

Background and aim

Cigarette smoking has negative effects on general health, including oral health. The aim of our study was to assess the correlations between nicotine dependence, exhaled carbon monoxide levels and oral hygiene status.

Methods

Smoker and non-smoker participants were enrolled in this observational study. The Fagerström test was used to classify nicotine dependences: low (score: 0–3), medium (score: 4–6) or high (score: 7–10). The oral hygiene status was classified according to the oral hygiene indices of plaque, calculus and gingival inflammation. Lastly, the exhaled carbon monoxide levels were measured with a MicroSmokelyzer (Bedfont Scientific Ltd., Kent, United Kingdom).

Results

Sixty five participants (50 smokers in the study group and 15 non-smokers in the control group) were enrolled between 11th and 29th of January 2016. No statistical differences were observed between the study group and the control group in terms of age (mean age±SD 23.5±1.9 and 24.0±1.5, respectively) or gender (50% and 26.6%, respectively). A statistically significant difference was observed between the 2 groups in terms of plaque, (p=0.036), calculus (p=0.001) and gingival indices (p<0.001). A positive correlation was found between the exhaled levels of carbon monoxide and the general Fagerström score (r=0.97, p<0.001) or the Fagerström score in smokers (r=0.93, p<0.001); a negative correlation was observed between the exhaled carbon monoxide levels and the number of tooth brushings daily (r=−0.41, p=0.001). The plaque index was statistically significantly associated with the exhaled carbon monoxide levels (p=0.008), general Fagerström score (p=0.016) and number of tooth brushings daily (p<0.001). The calculus and gingival indices were statistically significantly associated with the exhaled carbon monoxide levels (p<0.001), general Fagerström score (p<0.001) and score in smoker participants (p=0.029 and p=0.001, respectively) as well as the number of tooth brushings daily (p<0.001).

Conclusion

Our study found a significant association between the plaque, calculus and gingival indices and smoking. Moreover, nicotine dependence was significantly associated with the number of daily tooth brushings and the gingival index.

Association between Smoking and Periodontal Disease in Korean Adults: The Fifth Korea National Health and Nutrition Examination Survey (2010 and 2012)

BACKGROUND

This study aimed to evaluate an association between smoking, smoking cessation, and periodontal disease in Korean adults.

METHODS

The data were collected from 8,336 participants, aged between 20 and 64 years, who participated in the fifth Korea National Health and Nutrition Examination (2010 and 2012). Smoking status was assessed using self-administered questionnaires. Periodontal disease was defined as a community periodontal index ≥3 points. Logistic regression analysis was used to evaluate an association between smoking, smoking cessation, and periodontal disease after adjusting for age, sex, education, monthly income, diabetes, obesity, alcohol intake, and frequency of tooth brushing.

RESULTS

The risk of periodontal disease was higher among current smokers (odds ratio [OR], 1.49; 95% confidence interval [CI], 1.21-1.83) than never smokers. Among current smokers, the risk of periodontal disease was increased in smokers of ≥10 cigarettes/d, ≥20 years duration, and >10 pack-years compared with never smokers (P<0.05). Among former smokers, the risk of periodontal disease after 10 years since cessation declined to 0.56 (95% CI, 0.42-0.75) compared with current smokers and was indistinguishable statistically from never smokers.

CONCLUSION

Periodontal disease is significantly associated with smoking status in Korean adults.

Periodontal conditions of Colombian university students aged 16 to 35

Epidemiological data on the periodontal health and oral hygiene practices of young individuals in Latin America are limited. This study was conducted in a sample of 355 first-year students randomly selected from 3,251 new students entering the largest university in Colombia. Participants received a periodontal examination and were interviewed about oral hygiene practices. Specifically, this study assessed the relationship between oral hygiene practices (including smoking tobacco) and plaque accumulation and/or periodontal bleeding on probing (BOP). Participants had extensive plaque accumulation and BOP, with a mean O´Leary plaque index of 56% and mean BOP of 37%. Both measures were higher for proximal surfaces. Plaque indices of at least 50% were not associated with any oral hygiene factors; however, plaque index and use of dental floss were associated with a BOP of at least 50%. Frequency of tooth brushing was higher in female than in male participants. Only 5% of participants reported smoking tobacco. On average, participants had 2.7±4.6 pockets of at least 4 mm (18% of participants had ≥5 and 9% of participants had ≥10 pockets of this depth, respectively). On average, participants had 2.1±4.4 sites with clinical attachment loss of at least 2 mm (15% and 6% of participants had ≥5 and ≥10 sites with this level of loss). Only 8% of participants were diagnosed with moderate periodontitis, and no participants were diagnosed with severe periodontitis. In conclusion, although participants had high levels of plaque and BOP, signs of advanced destructive periodontal disease were minimal.

Periodontal disease and stroke: a meta-analysis of cohort studies

This review aimed to determine the association between periodontal disease and stroke incidence by a meta-analysis of cohort studies. Cohort studies that evaluated the incidence of stroke (fatal or non-fatal, ischaemic or haemorrhagic) and baseline periodontal status and calculated relative risk values were included. The quality of the included studies was assessed using an evaluation grid. The analyses were conducted separately for three outcomes: periodontitis, gingivitis and loss of teeth. Adjusted values of relative risk or of hazard ratio were used to assess risk values in each study. Random effects meta-analyses were conducted when data could be pooled. From the 743 references retrieved, only nine cohort studies were suitable for inclusion in this review. Quality scores of the studies varied greatly. Three prospective studies, which used reliable indicators of periodontal disease, obtained the highest scores. Conversely, three studies that used a subjective evaluation of stroke incidence or diagnosed stroke without imaging obtained the lowest score. The results of the meta-analyses varied depending on the outcome considered and the type of stroke. The risk of stroke was significantly increased by the presence of periodontitis [relative risk 1.63 (1.25, 2.00)]. Tooth loss was also a risk factor for stroke [relative risk 1.39 (1.13, 1.65)]. The risk of stroke did not vary significantly with the presence of gingivitis. This review shows that periodontitis and tooth loss are associated with the occurrence of stroke.

Effect of cigarette smoking on the periodontal health status: A comparative, cross sectional study

CONTEXT

Survey.

AIMS

The objective of the study was to evaluate the periodontal health status among cigarette smokers and non cigarette smokers, and oral hygiene measures.

SETTINGS AND DESIGN

Cross sectional study.

MATERIALS AND METHODS

The study included 400 male (200 cigarette smokers and 200 non smokers) aged 18-65 years. The subjects were randomly selected from the patients attending dental out-patient department of civil hospital and Himachal Dental College, Sundernagar. Community Periodontal Index (CPI) score was recorded for each patient and a questionnaire was completed by each patient.

STATISTICAL ANALYSIS USED

Chi square and t-test.

RESULTS

Periodontal condition as assessed by CPI score showed that there was statistically significant difference in the findings between cigarette smokers and non-smokers.

CONCLUSIONS

Within the limits of this study, positive association was observed between periodontal disease and cigarette smoking. It was found that cigarette smoking was associated with lesser gingival bleeding and deeper pockets as compared to non-smokers.

Estudo de base populacional sobre as condições periodontais e determinantes socioeconômicos em adultos residentes no município de Guarulhos (SP), Brasil, 2006

OBJETIVO: Este estudo descreveu a prevalência de condições periodontais e sua associação com variáveis demográficas, socioeconômicas e comportamentais em adultos de 35 a 44 anos residentes no município de Guarulhos, São Paulo, 2006. MÉTODOS: Foi realizado estudo transversal de base populacional com delineamento amostral por conglomerados. Os inquéritos e os exames foram realizados nos domicílios sorteados. Para avaliação da condição periodontal foi utilizado o índice Community Periodontal Index (CPI). Os dados foram apurados pelo programas EPIINFO 6 e STATA 10. Para o modelo de associação empregou-se a razão de prevalências (RP), calculada por meio de análise de regressão de Poisson, com correção para delineamento de amostras complexas e ponderação pelo peso populacional. RESULTADOS: Foram examinadas 263 pessoas em 237 domicílios. No estudo multivariado, com modelo ajustado para amostras complexas e ponderação populacional, a prevalência de sangramento gengival e cálculo dentário esteve associada significativamente ao fato de ser homem (RP=1,12, p=0,04), fumante (RP=1,11, p=0,01), ter menos de oito anos de estudo (RP=1,14, p=0,01) e não visitar o cirurgião-dentista (CD) há mais de dois anos (RP=1,19, p=0,00). Para a presença de bolsa periodontal, houve associação com adultos que relataram o hábito de fumar (RP=1,71, p=0,02) e apresentavam mais de dois anos sem frequentar o CD (RP=1,97, p=0,03). CONCLUSÃO: Houve maior prevalência (62,7%) de indivíduos com sangramento gengival e cálculo dentário em relação à presença de bolsas periodontais rasas ou profundas (26,6%); as primeiras, reversíveis, têm possibilidades de resolução por meio de procedimentos de atenção básica em saúde bucal.

Socio-economic position, smoking, and plaque: a pathway to severe chronic periodontitis

AIM

To report periodontal status and elucidate the relationship among socio-economic position (SEP), plaque accumulation, tobacco smoking, and periodontitis in a representative sample of adult Jewish people, aged 35-44 years, living in Jerusalem.

METHODS

This cross-sectional study was conducted using a stratified sample of two hundred and fifty-four 35-44-year-old adults in Jerusalem (limited to the Jewish population). A clinical examination (Community Periodontal Index and Plaque Index) and a self-administered questionnaire were applied.

RESULTS

Two hundred and fifty-four adults, mean age 38.6 (SD=3.3) years, participated. The response rate was 88%; intra-examiner κ values were above 0.87. The average number of healthy sextants was 1.18, while the average number of sextants with bleeding, calculus, shallow periodontal pockets, and deep periodontal pockets was 1.3, 2.6, 0.7, and 0.1, respectively. Lower level of education was associated with severe chronic periodontitis (SCP, p=0.012) and also with smoking (p=0.030) and higher level of plaque (p<0.001). Smoking was associated with higher level of plaque (p<0.001), which in turn was associated with SCP (p=0.020).

CONCLUSION

This study presented a potential explanatory pathway for the relationship between SEP and SCP. Low level of education was proposed as a distal determinant, leading to tobacco smoking and higher levels of plaque, and finally to SCP.

Periodontal health in Europe: future trends based on treatment needs and the provision of periodontal services--position paper 1

This review gives an update on recent epidemiologic data on periodontal diseases and a description of current periodontal services in Europe. A Medline search of articles published within the last decade with the keywords epidemiology, prevalence, periodontitis, tooth loss, and Europe was performed. Data on provision of dental services originated from international databases. Epidemiologic data on the prevalence of edentulism, the number of missing teeth, the prevalence of probing depth (Community Periodontal Index - CPI >or= 3 or Pocket Depth - PD >or= 4 mm), and clinical attachment loss (CAL >or= 4 mm) displayed a fragmentary picture within Europe. With respect to the limited data on periodontal health, Spain, Sweden, and Switzerland ranked as the healthiest among European countries in contrast to Germany where increased tooth loss and the highest prevalence of CAL >or= 4 mm were reported. The role of dental auxiliaries especially of dental hygienists and/or the medico-legal framework in which they work, appears to be an important factor in provision of effective periodontal care. Actual epidemiologic data on periodontal diseases are non-homogeneous and absent from several European countries. This emphasises the need for more national representative epidemiological studies with a uniform design to permit comparability between different nations. Merging actual epidemiologic data with former data on provision of periodontal care may help to explain differences in periodontal parameters on a population basis and to define future provision of dental care.
