RESUMEN
Follicular lymphoid hyperplasia is a rare reactive benign lesion of the oral mucosa. This is also known as pseudolymphoma as the features mimic the malignant counterpart Follicular lymphoma. In present case, a 34 year old male patient came with a nodular swelling in the posterior-lateral left side of tongue. Medical or dental history was non contributory. Swelling was painless, well demarcated, and about peanut sized. The swelling was provisionally diagnosed as either neurilemmoma, mucocele, or traumatic fibroma. Complete excision was performed, and tissue was sent to a private laboratory. Histopathological findings seen were germinal centers having a core of monotonous cells of the same size and demarcated mantle area mimicking the lymphoma. Immunophenotyping revealed diffused positivity for kappa and lambda expressions. CD10 was diffusely positive in germinal centers and BCl 2 was positive in the mantle area while negative in germinal centers. The final diagnosis given was follicular lymphoid hyperplasia. The entity mentioned in the present paper is an unusual variant of the benign lymphoproliferative lesion and very few cases are reported in the tongue area. Thus, it is important to understand the nature of this benign lesion in all aspects to avoid diagnostic dilemmas due to its malignant mirroring characteristics.
RESUMEN
Background: Dental implants use has significantly increased and the concentration of metal ions into blood may have detrimental effect of human body. The present study aimed to determine metal ions levels in blood of dental implants patients. Materials and Methods: 48 patients scheduled for dental implant surgery was assessed for measurement of titanium and aluminum pre-operatively and post-operatively at 6 weeks, 3 months, 6 months, and 1 year. Results: Out of 48 patients, males were 22 (45.8%), and females were 26 (54.2%). The mean ± SD titanium metal levels in blood pre-operatively was 2.34 ± 0.47 mg/dl, at 6 weeks was 2.35 ± 0.48 mg/dl, at 3 months was 2.37 ± 0.52 mg/dl, at 6 months was 2.37 ± 0.42 mg/dl, and at 1 year was 2.38 ± 0.51 mg/dl. A non-significant difference was seen (P > 0.05). The mean ± SD aluminum metal levels in blood pre-operatively was 4.4 ± 0.12 mg/dl, at 6 weeks was 4.45 ± 0.14 mg/dl, at 3 months was 4.7 ± 0.13 mg/dl, at 6 months was 4.7 ± 0.21 mg/dl, and at 1 year was 4.8 ± 0.17 mg/dl. A non-significant difference was seen (P > 0.05). Conclusion: A non- significant increase in titanium and aluminum ions level in blood of patients receiving dental implants was observed.
RESUMEN
Background: Abutment surfaces are being designed to promote gingival soft tissue attachment and integration. This confirms implant survival for long term by forming a seal around the prosthetics. Objectives: This study was done to compare the biocompatibility of three implant abutments: titanium uncoated, Ti-nitride coated, and modified polyetheretherketone (PEEK) with human gingival keratinocytes. Materials and Methods: The titanium-uncoated, titanium-nitride-coated, and modified PEEK discs (13 mm × 3 mm) were fabricated and compared with uncoated polyester cell culture discs, which were used as controls. These three implant abutments were evaluated for biocompatibility with respect to human gingival keratinocytes for viability, morphology, proliferation, and migration by scanning electron microscopy imaging and scratch wound healing assays. Measurements of roughness show changes between the investigated surfaces. Results: Keratinocytes cultured on all examined surfaces indicated adhesion and attachment. An assay of cell viability showed no substantial variances among the groups. The modified PEEK surface showed greater cell proliferation and migration among the three abutment materials. Conclusion: All three abutment material surface types showed similar epithelial biological responses. However, modified PEEK material showed the highest biocompatibility.
Résumé Contexte: Les surfaces des piliers sont conçues pour favoriser la fixation et l'intégration des tissus mous gingivaux. Cela confirme l'implantation survie à long terme en formant un joint autour des prothèses. Objectifs : Cette étude a été réalisée pour comparer la biocompatibilité de trois Piliers Implantaires : titane non revêtu, revêtu de nitrure de titane et polyétheréthercétone modifié (PEEK) avec des kératinocytes gingivaux humains. Matériaux et Méthodes: les disques PEEK non revêtus de titane, revêtus de nitrure de titane et modifiés (13 mm × 3 mm) ont été fabriqués et comparés à des disques de culture cellulaire en polyester non revêtus, qui ont été utilisés comme témoins. Ces trois piliers implantaires ont été évalués pour biocompatibilité vis-à-vis des kératinocytes gingivaux humains pour la viabilité, la morphologie, la prolifération et la migration par balayage électronique l'imagerie microscopique et les tests de cicatrisation des plaies. Les mesures de rugosité montrent des changements entre les surfaces étudiées. Résultats: Les kératinocytes cultivés sur toutes les surfaces examinées ont indiqué une adhérence et une fixation. Un test de viabilité cellulaire n'a montré aucune écarts entre les groupes. La surface PEEK modifiée a montré une plus grande prolifération et migration cellulaire parmi les trois matériaux de pilier. Conclusion: Les trois types de surfaces de matériaux de pilier ont montré des réponses biologiques épithéliales similaires. Cependant, le matériau PEEK modifié a montré la biocompatibilité la plus élevée. Mots-clés: Biocompatibilité, implant, kératinocytes, prothèses, microscopie électronique à balayage.

INTRODUCTION: The use of tobacco in all forms is increasing day by day globally causing its ill effects on oral as well as overall health of the people and affecting their sense of well-being and quality of life. AIM AND OBJECTIVES: The present study was done to investigate among patients the awareness of tobacco use and its ill effects on oral health. MATERIALS AND METHODS: This descriptive, cross-sectional study was conducted at Dr. RRK Dental College and Hospital, Akola. A total of 297 patients were asked using a self-structured questionnaire. RESULTS: Out of a total of 297 patients participating in the study, 48 (16.2%) were female and 248 (83.8%) were male. About 81.7% of the patients were aware that heart problems can be one of the ill effects of tobacco chewing, while 3.7% were still not sure about it. CONCLUSIONS: We found that patients had a knowledge about the impact of tobacco on oral health.
RESUMEN
BACKGROUND: Endodontically treated teeth should be prosthodontically managed properly to add life to the teeth, and hence the main aim of this study was to explore awareness, attitude, and practice of dental practitioners toward management of endodontically treated teeth and factors associated with it. MATERIALS AND METHODS: It was a cross-sectional, descriptive questionnaire study conducted among dental practitioners working in private clinics. The study was conducted in August 2019. The survey was conducted among 239 participants. In this study, a close-ended interview schedule was prepared for perception and practice of dental specialists. RESULTS: Most of the dental professionals (31.79%) preferred full coverage crown for restoring the grossly decayed endodontically treated teeth. Awareness regarding prosthodontic management of endodontically treated teeth was better among specialists (13.75%) than bachelor's degree holders. Attitude was neutral among most of the study participants (46.86%) and practice scores toward prosthodontic management of endodontically treated teeth was good. Gender and degree were significantly associated (P = 0.02*) (P = 0.05*), (P = 0.00***) (P = 0.05*) with awareness and practice of study participants. CONCLUSION: A majority of study subjects in this study had moderate awareness, neutral attitude, and good practice regarding restoration of endodontically treated teeth.
RESUMEN
BACKGROUND: Periodontitis has been reported to be associated with coronary artery disease. Research is needed to determine whether therapies that improve periodontal health also reduce systemic marker of inflammation associated with both diseases. AIM: To determine whether sub-antimicrobial dose-doxycycline (SDD) therapy can reduce systemic serum inflammatory biomarker C-reactive protein (CRP) in post-menopausal women who have chronic periodontitis. SETTINGS AND DESIGN: The study randomly assigned 128 eligible post-menopausal women with chronic periodontitis to a 90-day, twice-daily regimen of SDD or placebo tablets evaluated for 2 years, as an adjunct to periodontal maintenance therapy. MATERIALS AND METHODS: The study assayed blood samples for inflammatory mediators at baseline, 1 year, and 2 years. CRP was measured using a high-sensitivity enzyme-linked immunosorbent assay. RESULTS: SDD treatment reduced median high-sensitivity CRP by 18% (primary outcome = 0.02). CONCLUSION: Ninety-day SDD regimen in post-menopausal women significantly reduced the serum inflammatory biomarker CRP over a 2-year period.
