“…Retrospective Analysis at 6 years of Follow-up. Open Access J Dent Oral Surg 3: 1035 [14] states that in the first seven days after extraction, the greatest dimensional changes occur in the alveolar ridge with the mean maximum negative deviation, identified by 3D analysis, a bone loss of -1.7 mm ± 0 was recorded. , 3, compared to day 0 and the mean 3D reduction in alveolar ridge width was -3 mm at four months compared to one week data.…”

Context: Immediate implant placement in a fresh socket after extraction is an increasingly popular and established treatment option. However, active infection at the extraction site can adversely affect the outcome of this procedure. Aims: This study was designed to evaluate the clinical results of immediate dental implant placement in infected extraction sockets. Settings and Design: using a standardized protocol, which included the use of 3% hydrogen peroxide plus rifamycin 500 mg as irrigation for decontamination of the infected socket before implant insertion with submerged healing. Patients and methods: The sample consisted of 227 implants placed in 158 patients, the data were obtained through a retrospective review of the clinical registry selected of patients who received implants according to the protocol described. Statistical analysis used: A generalized binary response regression model was used. For all tests, the statistical significance value was set at p <0.05. Results: Of the 227 implants placed immediately in the infected sites using the described protocol with an average follow-up of 6 years of prosthetic loading, only 11 failed, resulting in a cumulative implant survival rate of 95.2%. Only the medical history / harmful habits factor (HM / HH) was significant (p = 0.002), in this group the success rate was 85.7%. However, in the group of healthy patients without harmful habits, the success rate rises to 98.8%. Conclusion: Immediate implant placement in infected sites using these protocols in healthy patients shows a survival rate similar to that published for implants placed in non-infected sites.

“…In in vivo bone regeneration, this novel composite scaffold sustained TSA release and induced robust bone regeneration in a mouse model of calvarial defects. Although this evidence has demonstrated that chitosan biphasic calcium phosphate loaded with trichostatin A (CS/ BCP/TSA) scaffolds can stimulate bone regeneration, controversies remain regarding its application in tooth extraction sockets because the bone remodeling process of the alveolar bone is different from that of other bone areas [28,29] In this study, we hypothesized that released TSA may be an essential osteogenic factor of the scaffold, and this epigenetically modulated scaffold may be used as an alveolar ridge preservation material after tooth extraction [30]. Therefore, we investigated the biological properties of released TSA using a pre-osteoblast cell line and evaluated the alveolar bone healing of tooth extraction sockets filled with CS/BCP/TSA scaffolds compared to conventional bone graft materials in a rat tooth extraction model.…”

Dental extractions are one of the most common surgical strategies used in humans. Following tooth loss, consequent atrophy in the alveolar height and width always occurs [1,2]. The alveolar bone undergoes volumetric changes owing to physiological remodeling and resorption [3]. This process is more pronounced during the first six months, and resorption is up to 50% of the alveolar ridge width that occurs in the first year after non-infected extraction [4][5][6][7]. Adequate dimensions of both hard and soft alveolar tissues, especially at the buccal aspect, are crucial for dental implants and prosthodontic treatment in a functionally optimal position. Ridge preservation is a surgical technique that prevents or minimizes dimensional changes in the alveolar process by dressing various bone grafts, barrier mem-branes, and/or biological agents in a fresh extraction socket [8][9][10].Bone tissue engineering (BTE) approaches with 3-dimensional porous scaffolds have long been considered in maxillofacial bone defect regeneration and alveolar ridge preservation [11][12][13]. Chitosan-based composite scaffolds incorporating ceramics such as hydroxyapatite or biphasic calcium phosphate (BCP) have been widely used as bone substitutes because of their excellent biocompatibility and mechanical property [14][15][16][17][18].The fundamental building blocks of chromatin called nucleosomes regulate gene expression by remodeling their 3-dimensional structure to perform gene regulation of eukaryotic cells. Modifying the histone structure by acetylation and deacetylation plays an essential role in regulating gene expression to alter cell growth, differentiation, and apoptosis. Histone acetylation, which relaxes the chromatin structure, is controlled by histone acetyltransferase (HAT). This enzyme transfers an acetyl group from the acetyl-CoA to a lysine residue. Histone deacetylation, which prevents transcription accessibility, is affected by histone deacetylase (HDAC) [19][20][21]. Small-J Prosthodont Res. 2023; **(**):
