The Effect of Cryotherapy on Treatment Outcomes for Pulpotomy

The goal of this clinical trial is to investigate the effect of cryotherapy on treatment outcome for pulpotomny in permanent mature carious posterior teeth. The main question is: Do cryotherapy improve treatment outcome in interested samples? \[primary hypothesis or outcome measure 1\] Treatment outcome by clinical and radiographic examination. Treatment outcome from different groups will be compared at designated time points.

Evaluation of Partial Versus Complete Pulpotomy in Carious Immature Molars Permanent Teeth Using Bioceramic Material

One of our major concerns and daily challenges is the management of carious immature permanent teeth, also known as young permanent teeth while preserving the vitality of the dental. Preserving radicular pulp tissue in these teeth allows continuing apical maturation and apical closure. Diagnosis and treatment of carious immature permanent molars are considered a challenging aspect of daily clinical routine, where constant irritation of the pulp without treatment leads to irreversible pulpitis and necrosis, which impedes the natural root development and its complete formation ; leading at the end to a decision of extracting the tooth .Therefore; when treating immature permanent teeth, the main goal is to preserve the vitality of the pulp to guarantee natural root development. Pulpotomy is a commonly employed treatment for this procedure involving either the removal of only the outer layer of damaged and hyperemic tissue in exposed pulps (partial pulpotomy or Cvek pulpotomy); which is a procedure staged between pulp capping and complete pulpotomy. Complete pulpotomy is the total removal of coronal pulp tissue and the placement of a wound dressing on the canal orifice. Followed by the placement of a biocompatible material to promote healing and regeneration of the remaining vital pulp tissue. In many studies, MTA showed high success rates in treatment of carious immature permanent molars. However, MTA is expensive and has poor handling characteristics, a long setting time and no predictable antimicrobial activity. Recently, new bioceramics have emerged as promising materials, showing good potential for vital pulp therapy in immature permanent teeth due to their biocompatibility and favorable clinical outcomes. Both MTA and bioceramics have almost similar compositions, but bioceramics materials contain titanium oxide and calcium phosphate, in addition to the absence of aluminum in its composition. Besides, bioceramics can release a high percentage of calcium ions early while maintaining this high percentage for 28 days, in contrast to the mineral trioxide, which showed a lower ability to release calcium ions more slowly. Therefore, this study will be conducted to compare the effectiveness bioceramic material in partial and complete pulpotomy of immature permanent molars.

Outcome of Full Pulpotomy Using Calcium Silicate Based Materials

Permanent teeth with carious pulp exposure and indicated for full pulpotomy will be treated using three different materials using aseptic technique and will be subsequently followed up clinically and radiographically at 6 months, 1 year and yearly up to 5 years.

Marginal Evaluation of Zirconia Reinforced Lithium Disilicate Partial Coverage Restoration of Egyptian Posterior Teeth.

Objective: To evaluate the marginal adaptation of the zirconia reinforced lithium disilicate (VITA AMBRIA) glass ceramic Inlay/Onlay compared with lithium disilicate(IPS emax Press) glass ceramic Inlay/Onlay in decayed posterior teeth.

Comparison of 3D Printed Composite Resin Crowns With Stainless Steel Crowns

The goal of this splith - mouth clinical trial is to compare 3D Printed Prefabric Composite Resin Crowns with Stainless Steel Crowns in healthy 50 children age between 5 and 9 with caries on more than one surface of the primary second molars. The main question\[s\] it aims to answer are: * 3D printed composite resin crown's survival rate is as succesful as stainless steel crowns * 3D printed composite resin crowns periodontal integrity is as succesful as stainless steel crowns Condition or disease : Carious Teeth Intervention/treatment: Procedure/Surgery: 3D Printed Prefabricated composite resin crown group Procedure/Surgery: Prefabricated stainless steel crown group
