Abstract

Nano-hybrid composite is a resin-based composite that combines mini and Nano-sized fillers. It has excellent mechanical properties and polish ability, but susceptible to color change. The color change of resin composite can be influenced by colored drinks such as tea which have various oxidation levels which will affect composition of tea coloring agent. The aim of this study was to determine color stability of Nano-hybrid composite after immersion in tea solutions with various levels of oxidation. Thirty disc-shaped specimens with diameteri10imm and thickness 2 mm were made from Filtek Z250XT Nano-hybrid composite. Specimens were stored in water at 37°C for 24 hours and then divided randomly into five groups which were immersed in distilled water, white tea, green tea, oolong tea, and black tea. Each group was immersed at 37°C for 22 days. Color was assessed in the CIELAB color system using a colorimeter before and after immersion. Data were analyzed with one way ANOVA and LSD Post-hoc test. Color changes was occurred in all groups with ∆E* as 3.209 for distilled water, 7.841 for white tea, 4.111 for green tea, 6.917 for oolong tea, and 8.340 for black tea. Color change in white tea, oolong tea, and black tea was significantly higher than in distilled water and green tea, also in black tea than in oolong tea. There are significant differences in color stability of Nano-hybrid composites after immersion in tea solution with various oxidation level, and green tea promotes the lowest color change

Abstract

Indirect resin composite veneer restoration (VIRK) is used as esthetic restoration for anterior teeth. Attachment between restoration and enamel surface was obtained using multi-step (MS) resin cement. Recently, a one step self-adhesive dual-cured resin cement (SADRC) was introduced. Determine failure analysis of VIRK bonded to enamel using MS resin cement and SADRC. Twenty specimens of buccal surface of enamel premolar were used. The specimens were flattened using silicon carbide no.2000. VIRK cylindrical specimens (diameter 3mm, thickness 3mm), were light-cured in Solidilite chamber (Shofu, Japan) for 3 minutes. VIRK specimens were then divided into: Group I with Multi-step resin cement (n=10) and Group II with SADRC (n=10). After 24h in incubator (37oC), Shear Bond Strength (SBS) were tested using Universal Testing Machine(Shimadzu AG5000). Failure analysis was determine using Stereomicroscope (Nikon, Japan) and Scanning Electron Microscope ( JEOL JSM 6510LA, Japan). Data were analyzed using Independent Sample T-Test (p<0.05). The average SBS value of group VIRK+MS was (16.97 + 7.67 MPa) higher than VIRK+SADRC (7.17 + 3.67 MPa). VIRK+Multi-step group has mixed failure, while VIRK+SADRC group has adhesive failure. Mixed failure shows strong bond between VIRK and enamel using Multi-step resin cement.

Abstract

The primary goal of periodontal treatment is regeneration of the supporting periodontal structures: i.e., formation of new bone, cementum, and new periodontal ligament collagen fibers. Successful using bone graft are many reported as bone replacement material promoting new bone formation, remodeling. Periodontal regeneration may be achieved by migration into periodontal defects and proliferation and differentiation of periodontal cells. Implementation. 14 year old young boy got trauma in his anterior upper jaw. Extra oral examination he got brushess of upper lip and bledding. Panoramic view shows bone fracture. His teeth of 21 and 22 got lost conections with bone, tooth mobility 40, lost clinical attachment of gingiva and palatal mucosa, and 8 - 12 mm of probing depth. Patients who experience head trauma around face, want to keep teeth in place as before, and do not require the use of prostheses. Teeth which are detached from the socket and experience shakiness 40 in extraction and cleaned using saline solution, and got a root canal treatment. Areas of trauma also be cleaned with saline solution and arranged the bone fragments. For bone remodeling, bone graft material may be used; demineralized freeze-dried bone allograft (DFDBA). Teeth in reimplantation must be splinted well. Patients should have good oral hygiene and do not consume food in the form of dense and chewy, and obey the traffic control. The success is determined by the parameters of probing depth, shakiness tooth, bleeding on probing, clinical attachment level, data taken before surgery and after six months of operation, if it is necessary, re-do the operation anyway. Results. After sixth month operation. There is no bleeding on probing and dental shakiness after six months of operation, and decreasing of probing depth of 10-15 mm to 3-4 mm. After 9 month of splint can be off. Conclusions. With all the limitations of experience, in this research can be concluded that we can maintain post-traumatic tooth in place of autotransplants technique by the periodontal tissue remodeling technique by using the additional of DFDBA bone graft material.

Abstract

The development of aesthetic rehabilitation techniques or smile design in the field of dentistry has brought a paradigm shift in the field of restoration and aesthetic. Dentists in planning treatment for patients should do a proper analysis on the patient, not just think about the treatment of one tooth, but the whole tooth being the problem in patient’s smile. This case aims to report the paradigm of “smile design” in the aesthetic rehabilitation on maxillary anterior teeth. The 23-year-old male patient came to the dental clinic with complaints of caries on the upper anterior teeth with wide damage. Pulp vitality tests showed positive results on teeth 13, 12 and negative on teeth 14,21,22,24. Radiographic examination revealed radiolucent image until dentin in teeth 12 and 13, as well as radiolucent image until pulp and widening of periodontal membrane on teeth 14,21,22,24. Case management in these patients is smile design analysis on maxillary anterior teeth. Direct composite veneer restoration is performed on teeth 13, 12, while root canal treatment is done on teeth 14, 21, 22 and 24 followed by fiber reinforced composite and all porcelain crowns. Patients is consulted to periodontic department for gingival aesthetic correction treatment with crown lengthening and gingival depigmentation. Aesthetic rehabilitation techniques or smile design involves evaluation of certain elements which is face analysis, jaw-facial relationship analysis, dental relation to the center line of the face, tooth on lips analysis, dental relation to the gingiva, and teeth shape and color analysis.These elements are all interconnected with each other.

Abstract

The surface of Glass Ionomer Cement (GIC) restoration changes because of mastication forces, shear force, other functional forces, and also tooth brushing process. Things that can also change the surface of GIC restoration is kind of food and beverage consumption, such as in Indonesia, lime and lemon juice are usual beverage, and mixed in food. The purpose of this study is to determine the changes in surface roughness of GIC restoration due to lime and lemon juice immersion. Three groups GIC sample, each of ten samples were 5 mm in diameter and 2.5 mm in height. Group 1 was immersed in mineral water (as control) for 10 days. In 10 days, Group 2 was immersed in lime juice, each day 9 times @ 15 minutes and brushed with soft toothbrush for 9 times @ 3 minutes. Similar way with group 2, 10 samples of group 3 was immersed in lemon juice. Samples immersed in mineral water show changes in surface roughness of 0.977+0.503 μm, while samples immersed in lime juice show 4.267+1.489 μm, and samples immersed in lemon juice show 4.293+1.311 μm. One way ANOVA test shows significant differences among the samples (p<0.05). Post hoc Tukey test shows significant difference (p<0.05) between group 1 and group 2 and between group 1 and group 3. However, there is no significant difference between group 2 and group 3 (p>0.05). Conclusion, lime juice and lemon juice cause changes in the surface roughness of GIC more than mineral water.
