Aggressive periodontitis: A clinico-hematological appraisal

Correlation Between ABO Blood Grouping and Erythrocyte Sedimentation Rate (ESR) in Periodontal Diseases

This study investigates the relationship between erythrocyte sedimentation rate (ESR) and ABO blood grouping in the context of periodontal disorders. Periodontal diseases, chronic inflammatory conditions that damage the tissues supporting teeth, can lead to tooth loss if left untreated. ESR, a common hematological test indicating systemic inflammation, has been linked to the severity of periodontal disease. ABO blood grouping, a hereditary trait, is linked to a higher risk of various oral and systemic diseases. By synthesizing existing research, this study explores the potential of the connection between blood type ABO and ESR levels in individuals with periodontal disorders, examining studies that assess the distribution of ABO blood types and corresponding ESR values among periodontal patients.

Evaluating the Long-Term Outcomes of Periodontal Surgery vs. Non-Surgical Treatment in Aggressive Periodontitis

Background

Aggressive periodontitis is a severe form of periodontal disease characterized by rapid tissue destruction and tooth loss. The optimal treatment approach for managing this condition remains a topic of debate.

Materials and Methods

A retrospective cohort study was conducted, involving patients diagnosed with aggressive periodontitis who received either surgical or non-surgical treatment between 2010 and 2020. Clinical and radiographic data were collected at baseline and regular intervals over a 5-year follow-up period. Surgical interventions included flap surgery, guided tissue regeneration, and bone grafting, while non-surgical treatments comprised scaling and root planning with or without adjunctive antibiotics. The primary outcomes assessed included changes in probing depth, clinical attachment level, tooth loss, and patient-reported quality of life measures.

Results

A total of 120 patients were included in the study, with 60 patients in each treatment group. The surgical group demonstrated significantly greater reductions in probing depth and gains in clinical attachment level compared to the non-surgical group (P < 0.05). Tooth loss was significantly lower in the surgical group over the 5 years (P < 0.01). Patient-reported outcomes also favored the surgical group, with improved oral health-related quality of life. However, the surgical group had a higher incidence of postoperative complications.

Conclusion

This study suggests that periodontal surgery yields superior long-term outcomes in the management of aggressive periodontitis compared to non-surgical treatment.

Circulating inflammatory cell profiling and periodontitis: A systematic review and meta-analysis

Inflammation is a key driver of common noncommunicable diseases. Among common triggers of inflammation, chronic gingival inflammation (periodontitis) triggers a consistent humoral host inflammatory response, but little is known on its impact on circulating inflammatory cell profiles. We aimed to systematically appraise all the evidence linking periodontitis and its treatment to circulating inflammatory cell profiles. From 6 databases, 157 studies were eligible for qualitative synthesis and 29 studies for meta-analysis. Our meta-analysis showed that participants with periodontitis exhibited a significant mean increase in circulating CD4⁺ , CD4⁺ CD45RO⁺ , IFNγ-expressing CD4⁺ and CD8⁺ T cells, CD19⁺ CD27⁺ and CD5⁺ B cells, CD14⁺ CD16⁺ monocytes, and CD16⁺ neutrophils but decrease in CD8⁺ T and CD14⁺⁺ CD16^- monocytes. Our qualitative synthesis revealed that peripheral blood neutrophils of patients with periodontitis consistently showed elevated production of reactive oxygen species (ROS) when compared with those of healthy controls. Some evidence suggested that the treatment of periodontitis reversed the exaggerated ROS production, but limited and inconclusive data were found on several circulating inflammatory cell profiling. We conclude that periodontitis and its treatment are associated with minor but consistent alterations in circulating inflammatory cell profiles. These changes could represent key mechanisms explaining the association of periodontitis with other comorbidities such as cardiovascular disease, diabetes, and rheumatoid arthritis.

The Relationship Between Periodontal Disease and ABO Blood Groups: A Cross-Sectional Study

PURPOSE

The objective of this cross-sectional study was to evaluate the relationship between ABO blood groups and periodontal diseases.

MATERIALS AND METHODS

Four hundred sixteen subjects (223 females, 193 males) were recruited according to the eligibility criteria. Periodontal examination was performed, including full-mouth plaque index (PI), bleeding on probing (BOP), clinical attachment level (CAL), and interproximal bone loss (IBL). ABO blood group patterns were determined based on self-reports, confirmed by medical records. The chi-squared test was done to evaluate the data (p < 0.05).

RESULTS

Out of the 416 subjects, 52.2% were blood group O, whereas 27.8% were blood group A. 46.8% of patients with blood group O had gingivitis and 49.6% had periodontitis. 31.2% of patients with blood group A had gingivitis,while 29.5% had periodontitis. The blood group with the lowest percentage among patients with gingivitis was AB, with a rate of 6.2%; in this blood group, 8.1% had periodontitis.

CONCLUSIONS

There is no association between periodontal diseases and ABO blood group types.

Is there an association between ABO blood grouping and periodontal disease? A literature review

Introduction

Although several studies have investigated the relationship between ABO blood group and medical diseases, few reports have explored the association with oral diseases, including periodontal disease (PD).

Aim

The aim of this literature review was to assess the association between the ABO blood grouping and PD.

Methods

We searched PubMed and Google Scholar databases using the following terms in different combinations: “ABO blood group,” “periodontitis,” “aggressive periodontitis (AP),” “risk factor,” and “Rhesus factor.” Databases were searched for articles published from 1977 to August 2016. Titles and abstracts of articles were screened for English-language papers describing clinical studies, case reports, or retrospective studies of oral health status in patients with different ABO blood groups. Letters to the editor, historic reviews, and articles including unpublished data were excluded. Reference lists of included studies were reviewed for additional original and review studies.

Results

We identified eight articles describing studies of the relationship between ABO blood groups and PD. The findings suggested a possible genetic basis in the association of the blood group AB with AP. Four studies showed that chronic periodontitis was more common among patients with blood group O.

Conclusion

ABO blood subgroup and Rhesus factor could constitute risk predictors in the development of PD.

Association of human leukocyte antigens Class I and Class II antigens with chronic periodontitis in East India

CONTEXT

Human leukocyte antigens (HLAs) have an important role in the determination of susceptibility and resistance to periodontal diseases in humans, which may vary from population to population.

AIMS

The aim of this study was to find out the association of HLA Classes I and II genes with chronic periodontitis in East Indian population.

MATERIALS AND METHODS

In a cross-sectional study design, a total of sixty participants of chronic periodontitis (CP) (mean age: 44.12 ± 5.85) and sixty subjects of periodontal disease-free controls (NP) Periodontitis free controls (mean age 41.85 ± 7.71) were analyzed for their various HLA combinations using serologic (microlymphocytotoxicity test) method. The results are further compared with the HLA profile of 100 samples of blood donors for which periodontal status was unknown. All the data were statistically analyzed by applying Chi-square test.

RESULTS

HLA-B7 (P = 0.003), DR7 (P = 0.001), DR53 (P = 0.001), and DQ3 (P = 0.001) were identified as susceptible phenotypes to CP, whereas HLA-A1 (P = 0.010), A3 (P = 0.001), and Cw4 (P = 0.001) phenotypes were identified to be associated with disease resistance.

CONCLUSION

The HLA-B7, DR7, DR53, and DQ3 alleles may represent as risk factors for CP in Eastern Population of India, whereas HLA-A1, A3, and Cw4 may indicate to protective factors for CP of the same.
