Evaluation of efficacy of different gingival displacement materials on gingival sulcus width.

AIM: The purpose of the present in vivo study was to measure the efficacy of different gingival displacement materials in achieving gingival tissue displacement and to compare the efficacy of Expasyl displacement paste (Pierre Rolland, France) and gingival displacement cord for gingival displacement. MATERIALS AND METHODS: Sixteen subjects were included in the study. Premolars were prepared to receive full veneer crown, gingival displacement was carried using gingival retraction cord and gingival displacement paste. Impression of the gingival sulcus was made. Sulcus width after displacement was measured under magnification. RESULTS: The mean displacement value of sulcus width was 0.21 ± 0.01 mm for the gingival retraction cord and 0.26 ± 0.02 mm for the gingival displacement paste. 'F' test was used for statistical analysis. Difference among the two test agents was statistically significant (p < 0.01). CONCLUSION: Gingival displacement paste showed better response in achieving horizontal displacement of the gingival sulcus than gingival retraction cord. CLINICAL SIGNIFICANCE: Gingival displacement helps in recording the unprepared tooth surface adjacent to the finish line in the impression being made, thereby helping a better marginal adaptation and emergence profile in the extracoronal restoration.

Antihyperhomocysteinemic and antihyperlipidemic effect of Trichilia connaroides in methionine-induced hyperhomocysteinemic animals.

The current study investigates the antihyperhomocysteinemic and antihyperlipidemic effect of chloroform and methanol extracts of the leaves of Trichilia connaroides in methionine-induced hyperhomocysteinemic rats. Hyperhomocysteinemia was induced in albino Wistar rats by oral administration of L-Methionine (1 gm / kg) and they were treated simultaneously with chloroform and methanol extracts (100 mg / kg) from the leaves of Trichilia connaroides. Serum homocysteine, lipid profile, and products of lipid peroxidation (MDA) in the heart homogenate were recorded and treated for statistical significance. Hyperhomocysteinemic animals recorded significantly elevated serum homocysteine changes in lipid profile (P < 0.01) and Thibarbituric acid reactive substances (P < 0.01), compared to the vehicle control animals. Animals treated with chloroform and methanol extracts recorded significantly (P < 0.01) lower serum homocysteine, entire lipid profile, LPO (P < 0.01), except a significant increase in HDL-cholesterol (P < 0.01) compared to hyperhomocysteinemic animals. Thus, we conclude that chloroform and methanol extracts of Trichilia connaroides have significant antihyperhomocysteinemic and antihyperlipidemic effects on methionine-induced hyperhomocysteinemic animals. Trichilia connaroides, therefore, holds promise as a cardioprotective herb.

Incomplete pancreas divisum with anomalous choledochopancreatic duct junction with choledochal cyst.

The coexistence of incomplete pancreas divisum, an anomalous choledochopancreatic duct junction, and a choledochal cyst is an extremely rare condition, described in only 3 patients in the available medical literature. The symptoms may be similar to any of these 3 distinct pathological conditions. Magnetic resonance cholangiopancreatography or endoscopic retrograde cholangiopancreatography is usually required for diagnosis. Management of symptomatic pancreas divisum may be accomplished with open accessory duct sphincteroplasty or endoscopic papillotomy with or without stenting. Treatment of choledochal cyst is by complete excision of the cyst whenever possible, with hepaticodochoenterostomy being the treatment of choice. Here, we describe a patient with this complex disorder who was successfully managed with endoscopic minor duct papillotomy with accessory pancreatic duct stenting and resection of the choledochal cyst with hepaticodochojejunostomy.
