Investigation of periodontal destruction patterns in smokers and non-smokers

Tooth- and implant-related prognostic factors in treatment planning

Following a comprehensive patient examination, including the assessment of periodontal and peri-implant diseases as well as considering the patient's needs, a pretherapeutic prognosis for each tooth and implant is given. Teeth and implants with a secure pretherapeutic prognosis require simple procedures and may be regarded as secure abutments for function and with a doubtful pretherapeutic prognosis usually need a comprehensive therapy. Such teeth and implants must be brought into the category with a secure prognosis by means of additional therapy such as endodontic, restorative, and surgical procedures. Teeth and implants with a hopeless pretherapeutic prognosis should be extracted/explanted during the initial phase of cause-related therapy (i.e., infection control). For example, teeth with vertical root fracture or unrestorable caries and implants with mobility or unrestorable malposition fall into the category of hopeless units. The primary goal of periodontal and peri-implant therapy should be to arrest disease progression. The latest consensus statement highlights that periodontitis can be successfully controlled and treated teeth can be retained for life. Nevertheless, for patients with uncontrolled contributing factors, the endpoints might not always be achievable, and low disease activity may be an acceptable therapeutic goal. Similarly, the management of peri-implantitis frequently requires surgical intervention following nonsurgical therapy due to incomplete treatment outcomes. Different surgical modalities can be effective and lead to significant improvement; however, achieving complete resolution of peri-implantitis is challenging, not always predictable, and can depend on multiple baseline factors. Therefore, this review aims at summarising available evidence on the rationale for incorporating systemic, lifestyle-related, clinical, and radiographic prognostic factors into treatment planning of patients diagnosed with periodontal and peri-implant diseases.

[Association between age-related macular degeneration and periodontal disease]

PURPOSE

To evaluate the association between age-related macular degeneration (AMD) and periodontal disease, two frequent conditions in the elderly, with some risk factors in common.

METHODS

Single center, pilot, case-control study performed in a center specialized in the diagnosis and management of AMD. Periodontal status was evaluated in 43 AMD patients and 19 controls. Fundus examination and a complete periodontal examination were performed in all subjects.

RESULTS

AMD patients have a greater percentage of 3-4mm clinical attachment loss compared to controls (47% vs. 38%, [P=0.039]). However, no significant difference was found between the groups with regard to the prevalence of severe periodontitis.

CONCLUSIONS

These results suggest an association between AMD and attachment loss characteristic of periodontal disease and support the need for larger prospective studies to elucidate the relationships between these 2 highly prevalent and potentially severe diseases.

Data visualization of the relationship between smoking and periodontal site-specific effects across the lifespan in the US adult population

BACKGROUND

Data visualization techniques were used to ascertain (1) site-specific effects of cigarette smoking on the periodontium compared to never-smokers; (2) patterns of site-specific effects by age among current and never-smokers using contour maps.

METHODS

Data from 10,713 dentate participants aged ≥30 years in NHANES 2009-2014 were used. Pocket depth (PD) and clinical attachment level (CAL) for six sites/tooth were ascertained by smoking status and plotted using contour maps to identify new patterns.

RESULTS

In the overall sample, 19% (n = 2015) were current smokers and 56% (n = 6013) were never-smokers. Contour maps of the overall sample showed teeth/sites most affected with mean PD > 2.1 mm were molars (2,3,15,18,19,30,31) in mesio-lingual (ML) and disto-lingual (DL) sites. Most affected sites for current smokers were interproximal sites of most posterior teeth. Among never-smokers, fewer teeth/sites were affected with PD > 2.1 mm, whereas among smokers, number of affected teeth/sites increased with age. Overall, teeth/sites most affected with mean CAL≥2.1 mm were noted in 2,3(ML), 3(DL), 14(DF, DL), 15(MF, ML), 18(ML), 19(DL, ML), and 30-31(ML, DL) with upper anterior teeth least affected. Among current smokers, several teeth/sites were affected (CAL≥2.1 mm): 2,3(all six sites), 4(ML, DL), 9(ML), 11-21(DL), 13-18(DF, ML, MIL, DL), 19-20(DF, ML, MIL), 14-18(MIF), 21(MIF, ML, DL), 22(MF), 23-27(MIL), 24-26(MIL, MF, DF in 26), 27(MF), 28(MF, ML, DL), 29-31(all 6 sites except MIF 30,31). As age increased, more teeth/sites were affected among smokers and by the 5th decade nearly all teeth/sites had CAL≥2.0 mm.

CONCLUSIONS

Contour mapping identifies patterns and dramatically visualizes the substantial periodontal site-specific differences. Current smokers had more affected teeth and/or periodontal sites with a different contour pattern than never-smokers.

Commercial Local Pharmacotherapeutics and Adjunctive Agents for Nonsurgical Treatment of Periodontitis: A Contemporary Review of Clinical Efficacies and Challenges

Periodontal infections tend to be site-specific, mostly confined to the periodontal pocket. With the surge of antibiotic-resistant bacteria, the trend is shifting towards other therapeutic modalities, especially locally delivered approaches that include other pharmacotherapeutic drugs and medical devices. This narrative review aimed to provide insights into the clinical efficacy of local drug delivery and adjunctive agents used in nonsurgical management of periodontitis. Electronic (PubMed/MEDLINE, CENTRAL, and EMBASE) and bibliographic searches of past systematic reviews were carried out to identify previous publications on the topic. Only relevant literature and randomized controlled trials published in English were selected. In addition, a literature review was developed based on the selected articles. Experimental drugs or agents were excluded. This review highlights the clinically proven and commercially available therapeutic agents related to the management of periodontal disease with comparisons of their clinical efficacies and challenges. A vast array of commercial local pharmacotherapeutic agents had been clinically tested, but the methodologies and clinical results varied within and between each agent used, causing difficulty in drawing conclusions and providing support to the superiority of one agent over another. Considering the benefit-cost ratio with the modest clinical results, the long-term usefulness of these agents remains debatable.

Tobacco-use patterns and self-reported oral health outcomes: A cross-sectional assessment of the Population Assessment of Tobacco and Health study, 2013-2014

BACKGROUND

Few studies consider simultaneously the oral health implications of nontraditional tobacco products and tobacco-use patterns. The authors aimed to evaluate self-reported gingival disease among cigarette smokers and users of other types of tobacco products.

METHODS

The authors used survey-weighted multivariable logistic regression to assess associations between different tobacco products, use patterns (for example, dual or multiple tobacco product use or product switching); and lifetime history of gingival disease diagnosis and treatment. They used the nationally representative (US) Population Assessment of Tobacco and Health study's Wave 1 (2013-2014) adult data (N = 32,320).

RESULTS

Overall, 12.1% of participants self-reported gingival disease diagnosis, and 19.1% reported receiving treatment. Groups with the highest adjusted relative odds for diagnosis (reference, lifetime tobacco never users) were pipe users (2.7; 95% confidence interval [CI], 1.3 to 5.3), e-cigarette users (2.9; 95% CI, 1.9 to 4.5), multiple tobacco product users (2.8; 95% CI, 2.4 to 3.4), and recent (< 12 months) quitters (2.8; 95% CI, 2.0 to 3.8). Similarly, odds of treatment report were highest among pipe users (2.3; 95% CI, 1.3 to 4.1), e-cigarette users (2.3; 95% CI, 1.3 to 4.1), multiple tobacco product users (1.6; 95% CI, 1.4 to 1.9), and recent quitters (1.7; 95% CI, 1.3 to 2.2).

CONCLUSIONS

Numerous tobacco-use patterns were associated with worse periodontal health compared with tobacco never users. These findings are consistent with previous biological and epidemiologic evidence linking tobacco use to poor periodontal health.

PRACTICAL IMPLICATIONS

Dental clinicians should anticipate various tobacco-use patterns among their patients, all of which may impact oral health. Oral health care professionals should remain informed of, screen for, and address the use of all tobacco products in practice.

Accuracy of cotinine serum test to detect the smoking habit and its association with periodontal disease in a multicenter study

Background

The validity of the surveys on self-reported smoking status is often questioned because smokers underestimate cigarette use and deny the habit. It has been suggested that self-report should be accompanied by cotinine test. This report evaluates the usefulness of serum cotinine test to assess the association between smoking and periodontal status in a study with a large sample population to be used in studies with other serum markers in epidemiologic and periodontal medicine researches.

Material and Methods

578 patients who were part of a multicenter study on blood biomarkers were evaluated about smoking and its relation to periodontal disease. Severity of periodontal disease was determinate using clinical attachment loss (CAL). Smoking was assessed by a questionnaire and a blood sample drawn for serum cotinine determination.

Results

The optimal cut-off point for serum cotinine was 10 ng/ml. Serum cotinine showed greater association with severity of CAL than self-report for mild-moderate CAL [OR 2.03 (CI95% 1.16-3.53) vs. OR 1.08 (CI95% 0.62-1.87) ] advanced periodontitis [OR 2.36 (CI95% 1.30- 4.31) vs. OR 2.06 (CI95% 0.97-4.38) ] and extension of CAL > 3 mm [ OR 1.78 (CI95% 1.16-1.71) vs. 1.37 (CI95% 0.89-2.11)]. When the two tests were evaluated together were not shown to be better than serum cotinine test.

Conclusions

Self-reported smoking and serum cotinine test ≥ 10ng/ml are accurate, complementary and more reliable methods to assess the patient’s smoking status and could be used in studies evaluating serum samples in large population and multicenter studies. Clinical Relevance: The serum cotinine level is more reliable to make associations with the patient’s periodontal status than self-report questionnaire and could be used in multicenter and periodontal medicine studies.

Gamma Glutamyl Transpeptidase, Smokeless Tobacco, Chronic Periodontitis: Exploring the Link

INTRODUCTION

Oxidative Stress (OS) is implicated in the pathogenesis of many systemic and oral diseases such as periodontal disease. Smokeless tobacco extract produces apoptosis and causes an imbalance between reactive oxygen species and antioxidants, such as Gamma Glutamyl Transpeptidase (GGT). Epidemiological research implied serum GGT within its normal range to be an early sensitive enzyme related to OS.

AIM

To assess how GGT fares as a biomarker in periodontitis subjects with or without the usage of smokeless tobacco and correlate it with clinical parameters.

MATERIALS AND METHODS

Ninety subjects were divided into three groups of healthy, chronic periodontitis, and smokeless tobacco users with chronic periodontitis from the dental outpatient department of P.M. Nadagouda Memorial Dental College and Hospital. Serum samples of patients were collected after obtaining consent and analyzed for GGT. Statistical Analysis was performed using ANOVA, and Pearson's correlation coefficient.

RESULTS

GGT levels were found to be significantly higher in chronic periodontitis patients compared to smokeless tobacco users with chronic periodontitis and healthy subjects. Conclusion: GGT may be used as a quick, easy and precise marker for measuring OS in patients with chronic periodontitis and smokeless tobacco users.

Quantitative Assessment of Calcium Profile in Whole Saliva From Smokers and Non-Smokers with Chronic Generalized Periodontitis

BACKGROUND

Measures of in vivo calcium status are important in understanding the mineralization capacity as it is an essential mineral component of both teeth and bone; and also play a vital role in the lipid profile and hormonal balance.

AIM

To evaluate the existence of any disturbances in calcium metabolism and absorption induced by smoking, by quantitatively assessing the variations in the salivary calcium level between smokers and non-smokers with periodontitis and relating to their periodontal status.

MATERIALS AND METHODS

A total of 50 male patients were selected and categorized as Group I (smokers with chronic generalized periodontitis) and Group II (non-smoker/ non-tobacco users with chronic generalized periodontitis). Clinical parameters such as Calculus Index and Community Periodontal Index were assessed. Subsequently two ml of unstimulated whole saliva was collected and subjected to biochemical analysis for the estimation of salivary calcium which was carried out in the next 20 min.

RESULTS

Salivary calcium levels were significantly higher in Group I (2.2700) compared to Group II (1.7260). Higher calculus index and CPI index score were also seen in Group I when compared to Group II.

CONCLUSION

Elevated salivary calcium level among the Group I emphasize the decreased calcium absorption efficiency among the smokers. High salivary calcium content hardens plaque more rapidly, indirectly influencing the level of oral hygiene.

Variations in tobacco control in National Dental PBRN practices: the role of patient and practice factors

We engaged dental practices enrolled in The National Dental Practice-Based Research Network to quantify tobacco screening (ASK) and advising (ADVISE); and to identify patient and practice -characteristics associated with tobacco control. Dental practices (N = 190) distributed patient surveys that measured ASK and ADVISE. Twenty-nine percent of patients were ASKED about tobacco use during visit, 20% were identified as tobacco users, and 41% reported being ADVISED. Accounting for clustering of patients within practices, younger age and male gender were positively associated with ASK and ADVISE. Adjusting for patient age and gender, a higher proportion of non-whites in the practice, preventive services and proportion on public assistance were positively associated with ASK. Proportion of tobacco users in the practice and offering other preventive services were more strongly associated with ASK and ADVISE than other practice characteristics. Understanding variations in performance is an important step toward designing strategies for improving tobacco control in dentistry.

Pattern of cigarette smoking effect on periodontal pocketing and attachment loss: a retrospective study

AIM

The aim of the present retrospective study was to evaluate the local effects of smoking on periodontium and to assess the patterns of periodontitis (pocket depths and attachment loss) in smokers and non-smokers.

METHODS

In this study, records of 126 non-smokers and 51 smokers (≥ 5 cigarettes/day) periodontitis patients were evaluated and probing pocket depth (PPD), clinical attachment level (CAL) and bleeding on probing (BOP) data were collected from clinical patients records. Patients' data were subject to two sample t-tests to assess the difference between the groups and to analysis of variance using the generalized linear model to seek associations between smoking and site positions, age and clinical parameters.

RESULTS

The difference between CAL of smokers and non-smokers was greatest at the anterior maxillary palatal sites (P = 0.002) and reached 1 mm. When the effect of different site positions as well as smoking as a between subject variable and age as a co-variate on the attachment level measurements were assessed using analysis of variance, significant effects for smoking, jaw (lower versus upper) and anterior-posterior position as well as age were detected. No significant interactions were found between smoking and any of the three position variables.

CONCLUSION

Lack of interaction between smoking and any of the three position variables indicates that the destructive effects of smoking on the periodontal tissues maybe mainly from systemic side-effects and almost independent of the site position within the mouth, although some additional local effects may be present in areas such as anterior palatal sites.

The effect of smoking on periodontal health of 15- to 16-year-old adolescents

BACKGROUND

Smoking is a severe risk factor for periodontal health in adults, but data on the effect of smoking on periodontal health in teenage populations are sparse. The aim of this study was to investigate the effect of duration and quantity of smoking on periodontal health in teenagers and possible differences between genders.

METHODS

The oral health of 501 adolescents (15- to 16-year-old boys [n = 258] and girls [n = 243]) was examined. A structured questionnaire about self-reported smoking and health habits was filled out, and bitewing x-rays were taken. Clinical examinations included measuring periodontal indexes, such as visible plaque index, bleeding on probing, root calculus (RC), probing depth, and attachment loss. Results were analyzed by generalized linear logistic regression.

RESULTS

Twenty-five percent of boys and 27% of girls were smokers. The boys and girls who smoked had higher RC values than non-smokers (P <0.001). The adjusted scores for smoking boys and girls were 17.3 (95% confidence interval [CI]: 8.6 to 31.7) and 13.6 (95% CI: 5.5 to 29.7), respectively. The adjusted scores for non-smokers were 10.4 (95% CI: 5.7 to 18.3) and 7.7 (95% CI: 3.3 to 17.3), respectively. Smoking boys and girls also had more periodontal pockets > or =4 mm than non-smokers: the score for boys was 4.6 (95% CI: 2.2 to 9.1), and the score for girls was 5.4 (95% CI: 1.1 to 23.2; P <0.001).

CONCLUSION

Smoking significantly impaired periodontal health in teenagers.

Comparison of periodontal and socioeconomic status between subjects with type 2 diabetes mellitus and non-diabetic controls

BACKGROUND

The association among periodontal conditions, socioeconomic status (SES), and diabetes has been reported. However, there is a lack of published data comparing periodontal conditions among individuals with poorly controlled type 2 diabetes mellitus (T2D). The aim of the present study was to compare the periodontal conditions and SES between subjects with T2D and non-diabetic controls.

METHODS

A total of 75 (31 males and 44 females) individuals with T2D (62 poorly controlled and 13 well-controlled) and 99 non-diabetic patients (healthy controls; 51 males and 48 females) participated in the study. Plaque index (PI), bleeding on probing (BOP), and probing depth (PD) were investigated. Random blood glucose level was recorded. Premolar and molar marginal bone loss (MBL) was measured digitally on scanned orthopantomograms.

RESULTS

Individuals with poorly controlled T2D had increased MBL in molars and maxillary premolars (P<0.05) compared to individuals with well-controlled T2D. PI, BOP, and PD of 4 to <6 mm were increased in individuals with poorly controlled T2D compared to those with well-controlled T2D (P<0.001). There was no difference between the diabetic groups when PD was >or=6 mm. Individuals with poorly controlled T2D had a lower SES compared to patients with well-controlled T2D (P<0.05). Illiteracy and the number of missing teeth were not different between the groups.

CONCLUSIONS

Radiologic and clinical indicators of periodontal destruction were increased in individuals with poorly controlled T2D. Low SES aggravated the periodontal condition in individuals with T2D.
