Objective: The objective of this study was conducted to evaluate clinically and radiographically the effectiveness of acemannan as direct pulp capping material in young permanent teeth. Subjects and Methods: The present study was performed on thirty six mandibular first young permanent molars with deep carious lesion indicated for direct pulp capping. The children aged from six to nine years old. After completely removing the infected dentine, teeth with a pinpoint pulpal exposure were randomly divided into two treatment groups: (group A) Acemannan or (group B) calcium hydroxide paste. In both groups, the remaining part of the cavity was filled with resin-modified glass ionomer filling. The teeth were assessed clinically and radiographically at different intervals (48 hours, 1.5 month and 3 months post-operative). Results: The present study revealed that, the clinical and radiographic success rate of acemannan was (77.8%), while Calcium hydroxide group showed a higher success rate (83.3%). Conclusion: Although the acemannan is a promising material but calcium hydroxide offers good clinical and radiographic results and success than acemannan but with no statistically significant differences.

Objective: The objective of this study was to evaluate clinically and radiographically the chitosan-zinc oxide eugenol mix as pulp capping material in primary teeth. Materials & Methods: The study was performed on 36 primary molars of patients aged from 4-8 years that were indicated for pulpotomy. The teeth were divided randomly into 2 main equal groups. Each group formed of 18 primary molars. Group A: 18 children teeth in which zinc oxide and eugenol (ZO/E) was used as pulp capping material after formocresol (FC) application. Group B: 18 children teeth in which Chitosan-ZO/E mix was used as pulp capping material. The teeth were assessed clinically and radiographically at 4 different intervals (preoperative, 24 hours, 6 weeks and 3 months postoperative), using standard clinical and radiographic criteria. Results: It was found that chitosan-ZO/E mix offers good clinical and radiographic results when compared with ZO/E after application of FC but with no statistically significant differences. Conclusion:ZO/E after application of FC (group A) showed (83.33%) success rate, while the Chitosan-ZO/E mix (group B) showed a higher success rate (94.44%). Chitosan-ZO/E mix is a promising material as pulp capping material with a high success rate and showing competitive properties to ZO/E after FC application.

Objective: The objective of this study was to assess the needle free jet anesthesia comfort-in on post extraction bleeding and inflammation in children. Subjects & Methods: The study was performed on 50 Egyptian children patients who needed extraction of teeth, according to the treatment plan, were recruited in the study. The patients were divided into two groups: 25 subjects in the needle free jet anesthesia comfort-in™ group and 25 subjects in the standard dental aspirating syringe group. Results: It was found that using jet technique resulted in less inflammatory mediators than using syringe technique. Conclusion: Jet technique is a promising technique in anaethesia with a high success rate and showing competitive properties to syringe technique. It has the power to be an alternative for syringe technique
