Evaluation of plasma reactive oxygen metabolites levels in obese subjects with periodontal disease.

Background: Obesity represents the systemic condition capable of influencing the onset and progression of periodontal disease. Obesity is associated with oxidative stress. Plasma level of reactive oxidative metabolites (ROMs) is measured as an indicator of oxidative stress in the body. The aim of this study is to assess and compare the plasma ROM levels in obese subjects with healthy and inflammatory periodontal status. Materials and Methods: Sixty subjects selected were grouped as 15 obese or overweight subjects with generalized chronic periodontitis, 15 obese or overweight subjects with generalized chronic gingivitis, 15 obese or overweight subjects with healthy periodontium, and 15 nonobese and healthy periodontium. The clinical periodontal parameters such as plaque index, gingival index, probing pocket depth, and clinical attachment level were measured. Blood samples were obtained to measure the plasma levels of ROM. Result and Conclusion: In this study, obese subjects with chronic periodontitis (Group I) had mean plasma ROM levels (442.3 ± 15.65 Carratelli unit [CARR U]) showing 100% subjects with high oxidative stress. Obese subjects with chronic gingivitis (Group II) had mean plasma ROM levels (358.7 ± 20.61 CARR U) indicating 86.7% subjects with oxidative stress. Obese subjects with healthy periodontium (Group III) had 46.7% subjects with slight oxidative stress, and the mean ROM level was 320.2 ± 17.57. Nonobese subjects with healthy periodontium (Group IV) had 80% of subjects with normal oxidative stress and the mean plasma ROM level was 296.9 ± 20.35 CARR U. The intra‑ and inter‑group comparison showed significant difference (P < 0.001). From our study, we report that obese subjects with periodontitis have more oxidative stress compared to obese subjects with healthy periodontium.

Multiple dental anomalies and aggressive periodontitis: A coincidence or an association.

Aggressive periodontitis (AgP) comprises a group of rare, often severe, rapidly progressive forms of periodontitis mostly characterized by an early age of clinical manifestation and a distinctive tendency for cases to aggregate in families. Abnormal dental morphology and position have been associated with severe periodontal diseases. The purpose of this paper is to report a case of multiple dental anomalies associated with AgP. This paper reports a case of unusual association of multiple dental anomalies to AgP. Clinical findings and history led to the diagnosis of localized AgP, and radiologically. It was associated with multiple dental anomalies, especially supernumerary roots. Thus, the present case represents a very interesting demonstration of AgP association with supernumerary roots and the nature of this association merits further investigations.

Plasma cell granuloma of gingiva.

An exceedingly rare case of gingival plasma cell granuloma is reported in a 40-year old female patient. The case presented as an exophytic mass of gingiva, clinically resembling traumatic fibroma. Histopathologic findings revealed dense sheets of plasma cells infiltrate. Immunohistochemistry for kappa and lambda light chains showed polyclonal (benign) staining pattern confirming a diagnosis of plasma cell granuloma. It is important to recognise this peculiar lesion because of its highly unusual incidence in involving the periodontium. Clinical features are usually suggestive of traumatic fibroma (benign) but histopathologicaly in early stages it closely resembles plasmacytoma (malignant). This case highlights the need to biopsy unusual lesions to rule out potential neoplasms and also emphasizes the need to submit all the excised tissue for histological examination regardless of clinical impression and/or perceived surgical success. Only by such practice can rare lesion of this type be diagnosed and their incidence studied.

Tissue engineering: prospect for regenerating periodontal tissues.

New advancements in technological fields, continually has had a major impact on dental practice. The emergence of tissue engineering and biomimetic concepts has enhanced the predictability of existing therapy and also has radically recast approaches towards the dentoalveolar reconstruction. Tissue engineering in the simplest sense is a combination of material sciences and biology to repair tissues and organs which will unquestionably offer an exciting therapeutic alternative that have never been available before. This article is a brief introduction to the ever expanding field of tissue engineering and its possible implication in periodontal regeneration.

Clinical evaluation of guided tissue regeneration procedure in the treatment of grade II mandibular molar furcations.

The management of furcation defects remains a challenge in periodontal therapy, Traditionally, furcation therapy involved scaling, rootplaning, furcation plasty and resective techniques. The purpose of this study was to clinically evaluate the potential of guided tissue regeneration in the treatment of mandibular molar grade II furcations using a nonresorbable barrier, TefGen-GTR and compare it with open flap debridement alone. Ten patients with similar bilateral grade II furcation lesions participated in the study. TefGen-GTR was placed in the experimental sites while the contralateral sites served as controls. Treatment effects were evaluated at six months reentry. Both groups showed gain in vertical and horizontal open probing attachment and defect depth reduction when compared to baseline values, with experimental sites showing statistically significant improvement over the controls. The results suggest that the nonresorbable Teflon barrier, TefGen-GTR, may be used as an alternative for treatment of grade II furcation invasions.
