Abstract

Carbonated hydroxyapatite is frequently used as bone graft material in dentistry. It is highly biocompatible, has osteoconductive properties, and functions as a drug delivery system. Propolis is a natural product from bees that has antibacterial and anti-inflammatory effects and is capable of accelerating wound healing. Incorporating propolis into carbonated hydroxyapatite was expected to enhance the wound-healing process by stimulating fibroblast growth and regenerating alveolar bone in the treatment of periodontitis. The aim of this study was to evaluate the effect of carbonated hydroxyapatite with incorporated propolis on the viability of NIH 3T3 fibroblast cells. This study used three treatment groups [carbonated hydroxyapatite with various concentrations of incorporated propolis (5%, 7.5%, and 10%)] and one control group (carbonated hydroxyapatite with no propolis). An MTT assay was carried out to assess cell viability, and absorbance readings were performed by using an ELISA reader. The data were analyzed by using one-way ANOVA. The results showed significant differences between all groups, and carbonated hydroxyapatite with 10% incorporated propolis has the highest cell viability level of all groups, while the control group has the lowest cell viability. In conclusion, adding propolis to carbonated hydroxyapatite could increase the growth of NIH 3T3 fibroblast cells. Keywords: Carbonated hydroxyapatite, Propolis, NIH 3T3 fibroblast cells, MTT assay

Abstract

The minimally invasive surgical technique (MIST) is a method for periodontal regenerative treatment by minimizing trauma so it can preserve vascular supply of the interdental papillae. This study aims to determine the effectiveness of the MIST method with the addition of a combination of hydroxyapatite and β-tricalcium phosphate (HA + β-TCP) in treatment of infrabony pockets in terms of alveolar bone density and osteocalcin levels of gingival crevicular fluid. The study sample was taken from 20 teeth with infrabony pockets (n = 20), which were divided into two groups: 10 teeth treated with MIST and the other group with open flap debridement (OFD). Both groups received combination of HA + β-TCP. The osteocalcin levels of gingival crevicular fluid were checked on day-0 prior to the flap surgery, day-7 and day-14 after flap surgery using the Human Osteocalcin Elisa Kit. Radiological evaluation of alveolar bone density at day-0 and day-90 was done using cone beam computed tomography. Data of osteocalcin levels were analyzed using two-way ANOVA and continued with LSD Post Hoc test, while data of alveolar bone density reduction were analyzed using the Independent t-test parametric test. The results showed that there was no significant difference (p > 0.05) in the values of alveolar bone density between the MIST and OFD groups on day-0 and day-90, while the osteocalcin levels in both groups showed an increase from day-0 to day-7 and a decrease from day-7 to day-14. There was a significant difference (p < 0.05) on day-0 and 7 and day-7 and 14 between MIST and OFD groups. The MIST method with HA + β-TCP was effective and further increases alveolar bone density and osteocalcin levels of gingival crevicular fluid.

Abstract

Various biomaterials have been utilized as additional material to help tissue regeneration in the open flap debridement (OFD) procedure. Platelet-rich fibrin (PRF) is an autologous platelet concentrate that contains many growth factors (GFs) and generally used as an additional biomaterial in OFD. However, PRF has several weaknesses, such as its consistency, which is hard to mix with another biomaterial, and its abundant sediment of regenerative cells resulted from high-speed centrifugation. Injectable Platelet Rich Fibrin (I-PRF) is one of the PRF derivatives that contain more regenerative cells. Due to the low-speed centrifugation, I-PRF has a liquid form. Certain GFs were also found in I-PRF, such as PDGF, TGF-β1, VEGF, IGF, EGF dan COL-Ia. In this study, we measured probing depth (PD), relative attachment level (RAL), and bone height as the healing parameter, to see the effectiveness of I-PRF addition and bone graft in the OFD for infrabony pocket as the aim of this study. Twenty (20) periodontal pockets were chosen (PD= 5-7 mm) and divided into OFD+I-PRF+bone graft (bg) group (group I) and OFD+PRF+bg group (group II) equally. The clinical evaluation was measured at the baseline, day-30, and day-90. Results showed that PD (p= 0.022) and RAL (p= 0.008) significantly increased in group I (PD 2.80 ± 0.42; RAL 2.50 ± 0.52) compared to group II (PD 2.10 ± 0.73; RAL 2.00 ± 0.67); however, there was no significant difference in the bone height (p= 0.194). Taken together, our data revealed that I-PRF+bg induces soft tissue regeneration in infrabony pocket treatment.

Abstract

Background: Chronic periodontitis is a disease that causes inflammation of the tooth supporting tissue, loss of periodontal attachment, and loss of alveolar bone. Root planning scaling treatment is carried out to remove irritants and microorganisms. The use of additional materials is required when the pocket depth is more than 5 mm. One of the herbal ingredients that has the potential as an adjunct to periodontal therapy is the 4% ocinumsanctum.Method: The sample consisted of 20 periodontal pockets with a depth of 4-6 mm which were given scaling root planning which were divided into two groups, namely 10 pockets given 4% maximum sanctum gel and 10 pockets given Metronidazole gel 25%. evaluations of the papillary bleeding index, TNF-α, and IL-β were performed at baseline, and on day 21. TNF-α and IL-β levels were taken through the gingival sulcus fluid and then tested using ELISA.Result: Papillary bleeding index, TNF-α, and IL-β levels showed a significant reduction in both groups but there was no significant difference between the 4% ocimum sanctum group and Metronidazole gel.Conclusion: ocimum sanctum application 4% post scaling root planning was able to lower papillary bleeding index score, TNF-α levels, and IL-β.
