“…6 Resin komposit memiliki kecenderungan untuk berubah warna setelah beberapa tahun pemakaian di dalam rongga mulut kristanti, di rongga mulut terdapat cairan yang disebut saliva dengan kandungan air yang tinggi, sehingga bahan restorasi akan terus terpapar oleh air yang mengakibatkan penyerapan air. 7,8 Penambahan E-glass fiber pada resin komposit memiliki tingkat stabilitas warna yang baik. 15 Hasil ini disebabkan karena E-glass fiber non dental memiliki komposisi alkali oksida Na2O dan K2O yang rendah dengan konsentrasi kurang dari 1%, komposisi NaO2 dan K2O yang rendah pada E-glass fiber dapat mempengaruhi stabilitas kimia fiber dalam mengurangi penyerapan air.…”

Latar belakang: resin komposit merupakan bahan restorasi yang paling populer saat ini karena memiliki kelebihan estetik yang baik yaitu sewarna gigi, namun resin komposit memiliki keterbatasan sifat fisik yaitu penyerapan air. Penyerapan air dan waktu perendaman berpengaruh terhadap stabilitas warna. Alternatif yang dapat dilakukan untuk mengurangi penyerapan air dan meningkatkan stabilitas warna yaitu digunakan resin komposit yang diperkuat oleh Fiber Reinforced Composite (FRC). Fiber yang paling sering digunakan dalam kedokteran gigi adalah E-glass fiber, akan tetapi di Indonesia E-glass fiber dental memiliki keterbatasan jumlah yang terbatas dan harga relatif mahal. E-glass fiber non dental dipilih sebagai alternatif karena komposisinya hampir sama dengan E-glass fiber dental dan biasa digunakan di dunia teknik. Tujuan: penelitian ini bertujuan untuk mengetahui perbedaan stabilitas warna E-glass fiber non dental reinforced composite akibat lama perendaman dalam saliva buatan. Metode: jenis penelitian kuantitatif menggunakan eksperimental laboratorium menggunakan one group pretest and posttest design. Sampel berbentuk lingkaran dengan diameter 13 mm dan tinggi 2 mm yang terdiri dari 2 kelompok; kelompok perendaman 7 hari dan 14 hari masing-masing terdiri dari 4 sampel. Uji stabilitas warna dilakukan dengan Spektrofotometer Uv-Vis dimana nilai absorbansi dan panjang gelombang yang didapat akan dihitung luas daerah sehingga dapat ditentukan nilai L*a*b* pada tiap sampel. Hasil: hasil rerata pengukuran stabilitas warna E-glass fiber non dental reinforced composite selama 7 dan 14 hari perendaman dalam saliva buatan menunjukkan nilai rerata 14 hari perendaman berada sedikit lebih tinggi dibandingkan 7 hari perendaman namun tidak bermakna. Uji independent sample t-test diperoleh nilai p=0,442 0,05 artinya tidak terdapat perbedaan yang signifikan antara perbedaan stabilitas warna E-glass fiber non dental reinforced composite akibat lama perendaman antara 7 hari dengan 14 hari. Kesimpulan: tidak terdapat perbedaan stabilitas warna E-glass fiber non dental reinforced composite akibat lama perendaman dalam saliva buatan. Penambahan E-glass fiber non dental pada resin komposit menunjukan stabilitas warna yang baik pada resin komposit.

A smile that is pleasing and beaming can be achieved by appropriate position of tooth, periodontal status of the tooth, type of prosthesis, as well as condition of the soft tissue. Any disharmony in these factors can lead to the formation of black triangles which are unesthetic. These unesthetic zones can be corrected by an interdisciplinary approach which includes orthodontic, prosthodontic, periodontic, endodontic branches. The treatment modality that is opted for a particular patient depends on the age of the patient, the biotype of gingiva, the form and condition of the radicular portion of the tooth as well as the interproximal space available. Surgical approach includes the recontouring, reconstructing, preserving of the interdental papilla. Surgical technique includes releasing, reflecting and stabilizing the interdental papilla. The non-surgical approach includes proper aligning of the maligned teeth by fixed orthodontic appliances thus decreasing the crest of bone and contact point distance. Endodontically the gingival black triangles can be treated by the use of composite resin in shades of pink to reproduce gingival contour. Open gingival embrasures can also be corrected with the help of ovate pontics that are easy to design and are more esthetic as compared to the conical pontic. To restore the scalloped architecture of the soft tissue, recontouring of the soft tissue surrounding the restoration followed by placement of ovate pontic can be done which is supported by the adjacent teeth. Open gingival embrasure can be masked with the use of silicones or removable acrylics as a gingival veneer. This type of prosthesis is also helpful in patients who have exposed radicular portion of the tooth because of excessive loss of alveolar bone. This review article discusses about the various etiologic factors accounting to the formation of open gingival embrasures, along with its classification and the various treatment modalities that are taken into consideration.

“…Tooth-colored restorations can be discolored by intrinsic or extrinsic factors. Intrinsic staining may generate due to physiochemical discoloration reactions within the material matrix [ 7 ]. In composite restoration, chemical discolorations may be attributed to oxidation of unreacted methacrylate group or polymer matrix.…”

Objectives: One of the most important aspects that determines the clinical lifetime of aesthetic restorations, is the color stability (CS) over the long term. This study aims to assess the effect of artificial aging and thermocycling in different staining solutions on the CS of bioactive restorative materials compared to conventional ones. Methods: The following four material groups were investigated: ACTIVA™ Bioactive (AB) (Pulpdent Corporation, Massachusetts, United States), Beautifil II (BF) (SHOFU Inc., Kyoto, Japan), Fuji II (FJ) (GC Corporation, Tokyo Japan), and Filtek™ Z350 XT (FT) (3M, Minnesota, United States). A total of 100 specimens were fabricated using an acrylic mold and then immersed in five staining solutions groups: coffee, black tea, Cola, mixed berry juice, and saline. Baseline shade (T0) was recorded using two spectro-photometer devices, VITA Easyshade® Advance (VITA Zahnfabrik, Baden-Wurttemberg, Germany) and Color-Eye® 7000A (X-Rite, Inc., Grand Rapids, Michigan, United States). Following this, the shade was recorded at 30 days (T1), three months (T2), and after 5000 thermocycles (5C-55C) (T3). CIE L*a*b* (International Commission on Illumination color space) data was used to calculate ΔE for each group. Results: All samples showed a significant color change (P<0.001) following one and three months of storage and after thermocycling. AB and BF showed the highest CS over time, whereas FT and FJ showed the least CS. Conclusion: The CS of restorative materials is mostly determined by their type, followed by staining solution type and thermocycling. The most potent solutions were coffee, tea, and berry juice.
