Periodontal Care Needs In Diabetic Patients: A Study Of The Prolanis Group In Banjarbaru City

South Kalimantan has seen a significant rise in dental and oral health issues, particularly periodontal diseases, which are prevalent among diabetic patients. This research aimed to analyze the periodontal status and the corresponding treatment needs of the Prolanis group, consisting of diabetic mellitus (DM) patients, at Sungai Ulin Health Center and South Banjarbaru Health Center, Banjarbaru City, during the second year of the study. A descriptive-analytical approach was employed to assess the periodontal tissue condition using the Community Periodontal Index of Treatment Needs (CPITN). A total of 65 respondents were examined, and the results indicated that 49.23% of the participants had tartar, while 30.78% displayed healthy periodontal conditions. Counseling on oral hygiene and scaling treatments were provided. The study emphasizes the importance of regular dental check-ups and proper oral hygiene practices, particularly in diabetic patients, to prevent further complications. Recommendations include brushing teeth twice daily and reducing the intake of cariogenic foods.

A Cross-Sectional Study of Serum Levels of Several Vitamins in Healthy and Unhealthy Periodontal Conditions

Vitamins are examples of micronutrients, which are nutrients needed in very minute quantities. They're crucial to metabolism and keeping tissues working properly. The purpose of this study was to determine whether vitamin deficiencies are associated with an increased risk of periodontitis. There was a total of 110 participants: 55 with chronic periodontitis spread throughout the mouth and 55 periodontally healthy individuals. Clinical parameters that were assessed included: Clinical attachment loss (in millimetres) and gingival index (in millimetres). Vitamin B12, vitamin D, folate, as well as vitamin E levels in serum samples were measured. Also measured were Beta-carotene and Beta-cryptoxanthin levels. The acquired data was aggregated and analysed using statistical programmes. All periodontal status clinical measures in the periodontitis group were statistically significantly different from those in the healthy volunteers group (p < 0.0001). Vitamin A precursors Beta-carotene and Beta-cryptoxanthin, folate, D, vitamins B12, and E, and vitamin E were all significantly lower in the periodontitis group compared to the healthy volunteers, but the difference was only statistically significant for vitamins B12 as well as D (p < 0.05). Finally, we conclude that serum micronutrient levels, particularly those of Vitamin A, Vitamin B12, and Vitamin D, may be modifiable risk factors for periodontal disease. In addition to practicing good dental hygiene on a regular basis, eating a diet rich in the right kinds of vitamins may play a significant part in warding off periodontitis.

Evaluation of NETosis (Neutrophil Extracellular Traps) biomarkers in smokers and nonsmokers periodontitis patients

Background To evaluate the NETosis biomarkers citrullinated histone H3 (citH3), neutrophil elastase (ELA), calprotectin (CALPRO), and myeloperoxidase (MPO) as indicators of inflammation in the severe stages of periodontitis III and IV in both (smokers and nonsmokers) patients, and to determine the correlation between NETosis biomarkers and clinical periodontal parameters. Methods This study recruited male subjects with an age range of (20-60) years; 60 were stage III and stage IV periodontitis patients, 30 were cigarette smoker, and 30 were nonsmokers. After applying the inclusion and exclusion criteria to evaluate their eligibility for recruitment, 25 control subjects with a healthy periodontal status and good oral hygiene maintenance were included. Unstimulated saliva was obtained and evaluated using an enzyme-linked immunosorbent assay, and the following periodontal parameters were documented: [plaque index, bleeding on probing, periodontal pocket depth, and clinical attachment loss]. Results The mean levels of all salivary NETosis biomarkers citH3, ELA, CALPRO, and MPO were elevated in the periodontitis groups (smokers and nonsmokers) than in controls. Moreover, the mean NETosis biomarker‘s mean levels were significantly higher in smoker than in nonsmokers. In addition, the correlations were significant between CALPRO and CitH3 in smokers and between ELA and CitH3 in nonsmokers. Conclusions The results of this study showed that the chosen salivary biomarkers of NETosis revealed elevated clinical accuracy in differentiating the studied periodontitis groups (smokers and nonsmokers) from controls. In addition, cigarette smoking increases the risk of periodontitis, and neutrophils in smokers with periodontitis exhibited more susceptibility to form neutrophil extracellular traps when compared with nonsmokers.

Metagenomic Characterization and Comparative Analysis of Removable Denture-Wearing and Non-Denture-Wearing Individuals in Healthy and Diseased Periodontal Conditions.

Removable denture wearers are at an increased risk of developing periodontal diseases due to biofilm deposition and microbial colonization on the denture surface. This study aimed to characterize and compare the metagenomic composition of saliva in denture wearers with different periodontal statuses. Twenty-four community-dwelling elders were recruited and grouped into denture wearers with active periodontitis (APD), non-denture wearers with active periodontitis (APXD), denture wearers with stable periodontal health conditions (SPCD), and non-denture wearers with stable periodontal health conditions (SPCXD). Saliva samples were collected and underwent Type IIB restriction-site-associated DNA for microbiome (2bRAD-M) metagenomic sequencing to characterize the species-resolved microbial composition. Alpha diversity analysis based on the Shannon index revealed no significant difference between groups. Beta diversity analysis using the Jaccard distance matrix was nearly significantly different between denture-wearing and non-denture-wearing groups (p = 0.075). Some respiratory pathogens, including Streptococcus agalactiae and Streptococcus pneumoniae, were detected as the top 30 species in saliva samples. Additionally, LEfSe analysis revealed a substantial presence of pathogenic bacteria in denture groups. In the cohort of saliva samples collected from community-dwelling elders, a remarkable abundance of certain opportunistic pathogens was detected in the microbial community.

Periodontal considerations during orthodontic intrusion and extrusion in healthy and reduced periodontium.

In patients with advanced periodontal disease, pathological tooth migration may occur, which may require subsequent orthodontic treatment for both aesthetic and functional purposes. When planning orthodontic treatment mechanics, intrusive or extrusive forces are frequently indicated. Understanding tissue reactions during these movements is essential for clinicians when devising a comprehensive orthodontic-periodontal treatment plan. This knowledge enables clinicians to be fully aware of and account for the potential effects on the surrounding tissues. The majority of our understanding regarding the behavior of periodontal tissues in both healthy and compromised periodontal conditions is derived from animal studies. These studies offer the advantage of conducting histological and other assessments that would not be feasible in human research. Human studies are nevertheless invaluable in being able to understand the clinically relevant response elicited by the periodontal tissues following orthodontic tooth movement. Animal and human data show that in dentitions with reduced periodontal support, orthodontic intrusion of the teeth does not induce periodontal damage, provided the periodontal tissues do not have inflammation and plaque control with excellent oral hygiene is maintained. On the contrary, when inflammation is not fully controlled, orthodontic intrusion may accelerate the progression of periodontal destruction, with bacterial plaque remnants being displaced subgingivally, leading to further loss of attachment. Orthodontic extrusion, on the other hand, does not seem to cause further periodontal breakdown in dentitions with reduced periodontal support, even in cases with deficient plaque control. This is attributed to the nature of the tooth movement, which directs any plaque remnants coronally (supragingivally), reducing the risk of adverse effects on the periodontal tissues. This specific type of tooth movement can be leveraged to benefit periodontal conditions by facilitating the regeneration of lost hard and soft periodontal tissues in a coronal direction. As a result, orthodontic extrusion can be employed in implant site development, offering an advantageous alternative to more invasive surgical procedures like bone grafting. Regardless of the tooth movement prescribed, when periodontal involvement is present, it is essential to prioritize periodontal therapy before commencing orthodontic treatment. Adequate plaque control is also imperative for successful outcomes. Additionally, utilizing light orthodontic forces is advisable to achieve efficient tooth movement while minimizing the risk of adverse effects, notably root resorption. By adhering to these principles, a more favorable and effective combined orthodontic-periodontal approach can be ensured. The present article describes indications, mechanisms, side effects, and histological and clinical evidence supporting orthodontic extrusion and intrusion in intact and reduced periodontal conditions.

Comparison of growth factor levels in injectable platelet-rich fibrin obtained from healthy individuals and patients with chronic periodontitis: a pilot study

BackgroundThis study aimed to assess and compare the concentrations of growth factors, white blood cells (WBCs), and platelets in injectable platelet-rich fibrin (i-PRF) derived from people with healthy periodontal conditions and those with chronic periodontitis.MethodsVenous blood samples were obtained from 30 patients diagnosed with chronic periodontitis (test group) and 30 participants with healthy periodontal conditions (control group). The i-PRF was then acquired from centrifuged blood. The growth factors (VEGF, IGF-1, TGF-β1, PDGF-BB and EGF) released from the i-PRF samples were compared between groups with ELISA testing. The amounts of WBCs and platelets were also compared.ResultsNo significant differences in the concentrations of growth factors were found between the groups (the mean values for the control and test groups were, respectively: IGF: 38.82, 42.46; PDGF: 414.25, 466.28; VEGF: 375.69, 412.18; TGF-β1: 21.50, 26.21; EGF: 138.62, 154.82). The test group exhibited a significantly higher WBC count than the control group (8.80 vs. 6.60, respectively). However, the platelet count did not show a statistically significant difference between the groups (control group 242.0 vs. test group 262.50). No significant correlation was observed between WBC count and growth factor level in either group.ConclusionsThe growth factor levels in i-PRFs did not exhibit significant difference between the two groups. This suggests that the levels of these growth factors may be unaffected by the periodontal disease.

Salivary Fractalkine Differentiating Periodontitis from Periodontally Healthy Subjects.

The chemokine "Fractalkine" (CX3CL1) and its corresponding receptor (CX3CR1), chemokine belonging to the CX3C family, have an essential role in developing several systemic inflammatory disorders. Accordingly, the proliferation, adhesion, and migration of inflammatory cells are all affected by it. In light of this, the present study attempts to address the following questions: (1) Is the salivary level of fractalkine and its receptor associated with periodontitis patients with different severities? (2) Is it possible to distinguish periodontitis from periodontally healthy subjects? This study included 30 individuals who had been considered controls, having healthy periodontium, and 90 patients with varying stages of periodontitis. The patients were equally divided into three groups: those with Stage I, Stage II, and Stage III. After each subject's saliva was collected, periodontal markers including bleeding on probing (BOP), probing pocket depth (PPD), and clinical attachment loss (CAL) were recorded. Enzyme-linked immunosorbent assays (ELISA) were used to detect the protein levels of salivary CX3CL1 and CX3CR1. In comparison to the control group, patients with periodontitis had statistically increased salivary concentrations of CX3CL1 and CX3CR1 (P < 0.001). Additionally, all clinical periodontal indicators (BOP, PPD, and CAL) had a strong association with salivary CX3CL1 and CX3CR1 levels. Furthermore, by using the ROC (receiver operating characteristic), both biomarkers showed a good ability to differentiate periodontitis from periodontally healthy subjects, and an excellent ability to distinguish Stage I and Stage III periodontitis from periodontally healthy subjects. The AUC for salivary CX3L1 and its receptors, CX3R, was 0.93 and 0.8, respectively, to distinguish Stage I from patients with good periodontal health. In contrast, the biomarkers' AUC for separating individuals with Stage III periodontitis from those in healthy periodontal conditions was 1. Fractalkine and its receptor are linked to periodontitis and may distinguish between periodontitis and healthy periodontal tissues, suggesting its role as a possible part of periodontal disease pathogenesis.

Bilateral transposed and impacted upper canines: case report

The aim of the study was to report, through a clinical case, the treatment of bilaterally impacted upper canines. A 9-year-old patient presented with prolonged retention of deciduous canines. Radiographic analysis revealed bilateral and horizontally impacted canines. After extraction of the deciduous teeth and access to the impacted canines, a transpalatal bar associated with a cantilever was used for traction without compromising neighboring teeth. Due to the location and complexity of the case, the upper canines underwent transposition with the first premolars. The lower arch was aligned and exhibited diastemas, which were treated with elastomeric chains and bull loops for space closure. The treatment goals were achieved with excellence in aesthetics, function, and healthy periodontal conditions

Association Between Periodontal Pathogens and Severity of Periodontal Diseases Among Adolescents in Kunming City: China

Objective: To investigate the association between periodontal pathogens and periodontal status among adolescents in Kunming City.Material and Methods: A total of 560 adolescents from five high schools within five urban districts in Kunming participated in this study. Clinical periodontal examination was assessed, and the levels of Porphyromonas gingivalis (P. gingivalis), Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans), Prevotella intermedia (P. intermedia), and Fusobacterium nucleatum (F. nucleatum) in saliva samples were examined using a real-time polymerase chain reaction (PCR). The relationship between periodontal pathogens and the severity of periodontal disease was investigated using multivariate logistic regression analysis. Results: The presence of P. gingivalis, A. actinomycetemcomitans, and P. intermedia was positively correlated with the extent of probing depth, clinical attachment level (CAL), and bleeding on probing. P. gingivalis and A. actinomycetemcomitans were detected at approximately 55-58% among adolescents with healthy periodontal status. P. gingivalis and A. actinomycetemcomitans were detected in all adolescents diagnosed with periodontitis (stage I or II), which was an increased number compared to healthy adolescents. It was found that P. gingivalis (odd ratio (OR)=7.03, 95% confidence interval (CI) 3.77-13.11) and A. actinomycetemcomitans (OR=5.37, 95% CI 2.73-10.57) were strongly associated with stage II periodontitis. F. nucleatum had no significant relationship with the occurrence of gingivitis and periodontitis.Conclusion: P. gingivalis, A. actinomycetemcomitans, and P. intermedia are important microbiological risk factors for periodontal diseases in adolescents.

Prevalence of oral lesions and evaluation of the periodontal status among diabetic females attending Princess Nourah Bint Abdulrahman University (PNU).

To evaluate the prevalence of different oral lesions and periodontal status among diabetic Saudi female patients in the College of Dentistry, PNU University. A retrospective study was performed by reviewing the files of all patients who visited the College of Dentistry, PNU University, during the last 5 years. We selected diabetic 20-40-year-old Saudi female patients. Ethical approval was obtained from the Institutional Review Board of PNU University. Data collection sheets were used to gather information on demographics, education, medical and dental history, and extra and intra-oral findings. Data on the duration of diabetes, any major complications, and type of diabetes therapy were retrieved from medical records. The data were entered into an Excel sheet, and descriptive statistics were performed. The analytical phase proceeded to correlate oral lesions with patient age, type of diabetes, and periodontal status. A total of 226 diabetic patients were found after reviewing the records. The most common oral mucosal lesions were traumatic ulcers (10.2%), cheek biting (8.8%), and fissured tongue (8.4%). Furthermore, 81.86% of them had periodontitis, and 18.14% had a healthy periodontal status. The prevalence of periodontitis among diabetic female patients is higher than that of oral lesions. Stage III periodontitis showed the strongest association to oral lesion.

Analysis of oral microbiome on temporary anchorage devices under different periodontal conditions

BackgroundTemporary anchorage devices (TADs) are maximum anchorages that have been widely used in orthodontic treatment. The aim of the study was to uncover whether a history of periodontitis would influence microbiome colonization on the TAD surface.ResultsPatients were grouped by periodontal evaluations before the orthodontic treatment. Patients with healthy periodontal conditions were classified as the healthy group, and patients diagnosed with periodontitis stage II or even worse were classified as the periodontitis group. Scanning electron microscopy (SEM) was used to analyze the existence of biofilm on the surface of 4 TADs from the healthy group and 4 TADs from the periodontitis group. Fifteen TADs from the healthy group and 12 TADs from the periodontitis group were collected. The microorganisms on the surface of TADs were harvested and analyzed by 16S rRNA gene sequencing. α-diversity indices and β-diversity indices were calculated. Wilcoxon’s test was used to determine differences between genera, species as well as KEGG functions. SEM analysis revealed bacteria colonization on the surface of TADs from both groups. Principal coordinate analysis (PCoA) based on β diversity revealed differential sample clusters depending on periodontal conditions (P < 0.01). When comparing specific genera, Fusobacterium, Porphyromonas, Saccharibacteria_(TM7)_[G-1], Dialister, Parvimonas, Fretibacterium, Treponema were more enriched in TADs in the periodontitis group. In the KEGG analysis, TADs in the periodontitis group demonstrated enriched microbial activities involved with translation, genetic information processing, metabolism, and cell motility.ConclusionsThis analysis elucidated the difference in total composition and function of TADs oral microorganisms between patients periodontally healthy and with periodontitis.

Association between Periodontitis and HbA1c Levels in Non-Diabetic Patients: A Systematic Review and Meta-Analysis.

A high detection rate of diabetes among dental visitors has been reported recently. This systematic review aimed to evaluate the association between periodontitis and glycated hemoglobin (HbA1c) levels among non-diabetic individuals. The EMBASE, MEDLINE, Web of Science, Cochrane Library, PubMed, and Open GREY databases were searched, and observational studies published until 1st June 2023 were identified. A methodological quality assessment was conducted based on the original and modified versions of the Newcastle-Ottawa scale. Cohort, case-control, and cross-sectional studies that performed clinical periodontal examinations and measured HbA1c levels in non-diabetic adults were included. A meta-analysis was conducted to estimate the weighted mean difference (WMD) between individuals with and without periodontitis. In total, 29 case-control and 5 cross-sectional studies were selected from 2583 potentially eligible articles. Among them, sixteen case-control and three cross-sectional studies with moderate to high quality were selected for the meta-analyses. The HbA1c levels in periodontitis patients were significantly higher than those in individuals with healthy periodontal conditions (WMD = 0.16; p < 0.001) among the non-diabetic populations. This study reveals a significant association between periodontitis and HbA1c levels in non-diabetic populations. Thus, HbA1c screening may be recommended to detect potential hyperglycemia in non-diabetic periodontitis patients.

Cystatin SN (CST1) as a Novel Salivary Biomarker of Periodontitis.

Identification of biomarkers could help in assessing periodontal health status and monitoring treatment outcomes. Therefore, the aim of this cross-sectional study was to identify potential innovative salivary biomarkers for the diagnosis of periodontitis using an untargeted proteomic approach. Forty-five healthy non-smoker participants diagnosed as having periodontally healthy conditions (H), severe periodontitis (P), and healthy but reduced periodontium after active periodontal treatment (T) were consecutively enrolled (15 per each group) in the study. A higher number of spots were identified in the proteome of unstimulated whole saliva collected from H and T subjects compared with P group, mainly within the range of 8-40 kDa. Protein spots of interest were analysed by MALDI-TOF-MS, allowing the identification of cystatin SN (CST1) isoform, as confirmed by Western blot. CST1 was markedly expressed in the H group, while it was absent in most P samples (p < 0.001). Interestingly, a distinct CST1 expression was observed in saliva from T patients. CST1 was negatively correlated with the percentage of pathological sites (p < 0.001) and was effective in discriminating active periodontitis from healthy periodontal status (whether H or T). Therefore, salivary CST1 may be a promising non-invasive biomarker for periodontal disease diagnosis and monitoring.

Poor oral health predicts cognitive impairment in elders

AbstractBackgroundTooth loss, periodontal disease, dementia, and Alzheimer’s disease share several risk factors in older adults. Several previous studies have reported positive associations between these dental problems and global cognitive defects. However, limited is known about the relationships among multiple dental/periodontal statuses and different cognitive domains.MethodThis six‐year (2011‐2017) cohort study includes 515 older adults (65+). Global cognition was assessed by Montreal cognitive assessment‐Taiwan version (MoCA‐T). For cognitive domains, we used logical memory tests (immediate and delayed theme and free recall) in Wechsler Memory Scale‐Third Edition (WMS‐III) to assess memory. Trail Making Test A and B was used to assess attention and executive function, respectively. Digit span‐forward and backward was used to evaluate attention and working memory/short‐term memory, respectively. Verbal fluency tests were used to assess category/semantic fluency. A Z‐score was calculated for each cognitive domain‐specific test according to baseline mean and standard deviation. Oral health status includes tooth defect (dental caries, tooth wear, cervical abrasion, retained root or crown fracture), periodontal health (disease severity from healthy periodontal status, gingivitis to periodontitis), and arch integrity (no tooth loss nor retained root or crown fracture). Generalized linear mixed models were used to assess the associations above adjust important covariates.ResultAt baseline, periodontitis was associated with poor performance in executive function [Trail Making Test A: b = ‐0.14, 95% confidence interval (CI) = ‐0.27 to ‐0.01]. The association between baseline severity of tooth defect and poor memory decreased (logical memory‐immediate theme recall: b = ‐0.05, 95% CI = ‐0.10 to ‐0.01); similarly finding was found for attention domain (digit span‐forward: b = ‐0.04, 95% CI = ‐0.07 to ‐0.001). At baseline, loss of arch integrity was associated with a better working memory/short‐term memory (digit span‐backward: β = 0.18, 95% CI = 0.01 to 0.36); as follow‐up time increased, this association decreased over six years (β = ‐0.04, 95% CI = ‐0.07 to ‐0.003).ConclusionPeriodontitis, tooth defects, or arch integrity was associated with poor performance of cognitive domains (memory, attention, and executive function) over time. A oral health evaluation may serve as predictors of the preclinical phase of dementia in its upcoming years.

Knowledge and practices regarding oral health and hygiene and its correlation with periodontal health in pregnant women, visiting hospitals of prime foundation

Objectives: To determine the periodontal health of pregnant women by using Community periodontal index of treatment needs (CPITN). To determine the oral health knowledge of pregnant women during pregnancy. To determine the correlation of knowledge and oral hygiene practices with periodontal health in pregnant women. To compare periodontal health, oral health knowledge and practices in different social classes during pregnancy. Methods and materials: A Cross-sectional study was carried out on 384 pregnant patients visiting gynea OPDs of Mercy, Kuwait, prime teaching hospitals and dental OPD of Peshawar dental hospital following inclusion and exclusion criteria and written consent was taken. Closed ended questionnaire was used consisting of 5 parts i-e age, trimester, oral health assessment (CPITN), oral health knowledge, oral hygiene practices and socioeconomic status. Results: Out of 384 patients 222 (57.8%) had healthy Periodontal status, followed by 75 (19.5%) having pocket depth between 3.5 to 5.5, calculus having 66 (17.2%), bleeding on probing were only 21 (5.5%) patients, whereas no patients were having pocket more than 5.5. 22(5.7%) had good oral health knowledge, 350 (91.1%) had satisfactory and 12 (3.1%) had poor oral health knowledge.

Paraoxonase-1, a novel link between periodontitis and ischemic heart disease: A case-control study.

Periodontitis is a chronic inflammatory disease and might be a potential risk factor for ischemic heart disease (IHD). However, the link between periodontitis and atherosclerosis is not yet fully understood. Paraoxonase-1 (PON-1) is a new biomarker representing both anti-atherosclerotic and antioxidant activity, which also acts against dental biofilm formation and periodontitis. The possible contributing role of PON-1 in the relationship between periodontitis and atherosclerosis has not been studied to date. The aim of the present study was to investigate the serum level of PON-1 with regard to the periodontal status in IHD patients. In this case-control study, 67 patients with IHD underwent a periodontal examination and were accordingly allocated to one of the 2 study groups: the case group with chronic periodontitis (n = 36); or the control group with a healthy periodontium (n = 31). Serum PON-1 activity was measured by means of colorimetric analysis. There were no significant differences between the groups in terms of demographic data, cardiac risk factors, initial biochemical test results, cardiac pump function, and the number of grafted vessels. The activity of PON-1 in cardiac patients suffering from periodontitis was significantly lower than in cardiac patients with a healthy periodontal status (53.01 ±7.53 U/mL and 59.11 ±9.95 U/mL, respectively; p = 0.007). This finding suggests that the combination of IHD and periodontitis is associated with lower PON-1 activity. Further studies might be required to assess the possible role of periodontal treatment in increasing PON-1 activity and reducing IHD severity.

Dental Implants in Patients with Osteogenesis Imperfecta - Clinical and Radiographic Outcome in Six Patients.

To investigate the survival rate of dental implants in patients diagnosed with osteogenesis imperfecta (OI). The study is a retrospective analysis of six individuals (2 males, 4 females) with OI (type I, III and IV) with a total of 25 dental implants. Clinical examination included plaque index, gingival index, periodontal pocket depth for each implant, presence of pus, and loosening of the implant(s). Marginal bone loss was measured on radiographs. The observation period ranged from 2-17 years (mean:7.5 years, median: 5 years). The overall implant survival rate was 80%. One patient with OI type III lost five implants. However, four out of five lost implants functioned for 11 years. Dental implant treatment seems to be a valid option for replacing missing teeth in OI patients. It is recommended that patients diagnosed with OI undergo the same preoperative evaluation as regular dental implant patients with special emphasis on a healthy periodontal status and ideal oral hygiene.

Periodontal Status and Gingival Conditions of the Tea Workers

Background: Periodontitis and gingivitis are prevalent chronic inflammatory diseases. The examination of the periodontal and gingival conditions is complex and requires a proficient dental healthcare provider to detect the patient’s definite problems.&#x0D; Methodology: The study was designed as a cross-sectional study to assess the periodontal status and gingival conditions of the 372 tea workers in the purposively selected Premnagar tea garden located in Moulvibazar district, Sylhet 3200, Bangladesh. ‘Community Periodontal Index’ (CPI) was used to measure the periodontal status.&#x0D; Results: Most of the workers (38.2%) were from the age group ≥37 years and illiterates (62.1%). More than two-fourths (57.8%) had detected calculus during probing, one-fourth (25.3%) had a shallow pocket and only 11.6% had healthy periodontal status. The prevalence of poor periodontal status was 88.4%. Among the dental cleaning aids such as toothbrush users, 15.6% had healthy periodontal status, whereas the smokeless tobacco non-users (22.6%) and pan-supari non-chewers (75.0%) had healthy periodontal conditions. The level of periodontal status factors was statistically significant with age, educational qualification, and monthly household income (p&lt;0.05) of the workers.&#x0D; Conclusion: The study warrants poor periodontal health status among the tea workers. It is essential to do the periodical assessment of the periodontal condition, risk factors analysis, and management complications by establishing dental health corners in tea garden health settings.&#x0D; Eastern Med Coll J.
