Classification systems for gingival recession and suggestion of a new classification system

Gingival recession is one of the most usual esthetic concerns associated with the periodontal tissues. Classification of such condition is important to diagnose, determine the prognosis, and frame the treatment plan. Various classifications have been put forward since decades to classify gingival recession. Miller's classification is the widely used classification among all classifications, but certain drawbacks have been noted in this classification. Therefore, an effort is made to review most commonly used classification systems for gingival recession, and their drawbacks further come up with a proposal of new classification system for gingival recession.

To Establish The Involvement Of Central Dopaminergic And Serotonergic Mechanism Of Ginger-Juice On Amphetamine And Lithium Treated Rat.

Background & Objective: To establish the involvement of central dopaminergic and serotonergic mechanismof ginger-juice (ZINGIBER OFFICINALE ROSCOE) CNS parameters in rat. Methodology: (A) Albino rats (n=6-12) were administered G.J at two doses (2ml & 4 ml/rat, p.o) as single administration and chronic treatment over period of 30 days. Following this assessment was done. Effect of treatment with G.J acutely and chronically (30days) administered, was assessed. Parameters used during assessment were total acidity, gastric volume & pH and ulcer index ‘UI’(acute and chronic). Results & Conclusion: Ginger administered itself did not affect loco motor activity as well as amphetamine-induced enhancement of loco motor activity.Lithium induced head twitches were enhanced after chronic administration indicating enhanced serotonergic system in the central nervous system.

The Analgesic Effects Of Ginger-Juice (Zingiber Officinale Roscoe) On Wistar Albino Rat.

Background: In the view of contradictory reporting concerning analgesic effect, it was planned to investigate the analgesic effect of ginger-juice (ZINGIBER OFFICINALE ROSCOE) on wistar albino rat. Methodology: Wistar albino rats (n=6-12) were administered ginger juice (GJ) at doses (4ml/rat, p.o) as single administration (single dose) and repeated dose over a period of 7 days. Effect of treatment with G.J single and repeated (7days) dose was assessed. Parameter used during assessment was licking of paw after placing the rate on analgesiometer heated up to 50C. Results: The single and repeated administration of GJ (4ml/rat,p.o for 7 days) did not indicate analgesic effect on hot plate model. Conclusion: administered itself did not show analgesic effect on hot plate model.
