Wound healing is a complex and dynamic process that involves a series of intricately regulated phases, each contributing to the restoration of tissue integrity. This comprehensive review dives into the fundamental aspects of wound healing, exploring the physiological mechanisms, phases, and influencing factors. The review begins with describing the significance of wound healing and navigates through sequential phases, such as hemostasis and inflammation, proliferation, remodelling, wound classification and closure techniques, thus providing insights into the diverse strategies employed in clinical settings. Much focus lies to bone healing, addressing both primary and secondary healing mechanisms, as well as the bone healing in extraction sockets. A significant segment of the review explores the factors affecting wound healing, which are categorized into local, surgical, and systemic factors encompassing ageing, diabetes mellitus, hormonal changes, immunocompromised conditions, medications, smoking, alcohol consumption, obesity, and nutrition deficiency. A synthesis of the reviewed content highlights the interplay of these factors in the ‘wound healing’ process. Understanding these elements is imperative for clinicians and researchers alike to develop effective therapeutic interventions tailored to individual patient needs. This review serves as a valuable resource for those seeking a comprehensive understanding of the intricate dynamics of wound healing in the human body.

Following tooth extraction, resorption in alveolar bone results in narrowing of remaining ridge in the extraction site leading to compromised functional and aesthetic outcomes. The overall goal of the present article is to shed light on the importance of the socket preservation procedure in preserving the original bone dimensional contours, while comparing two essential approaches, using non-resorbable high density d-PTFE membranes v/s the non-cross linked collagen resorbable membranes, by assessing the clinical results in terms of regenerated bone volume, postoperative complications and evaluation of keratinized tissue in grafted areas with either one of the above mentioned membranes.

Dyspepsia is a condition resulting from problems related to poor digestion and changes in the sensitivity of the stomach mucosa. It is usually related to diseases such as gastritis, gastroesophageal reflux disease, peptic ulcer and neoplasms of the upper gastrointestinal tract. Dyspepsia is strongly related to the presence of Helicobacter pylori bacteria. Dyspepsia is characterised by pain, pyrosis (heartburn or a burning sensation), anorexia (loss of appetite), abdominal distention, gastric bloating, eructation, flatulence, nausea and a feeling of satiety. Fantogeusia (bitter taste) and halitosis can also be observed. The purpose of this article is to present the case of a patient with dyspepsia caused by erosive gastritis. After periodontal treatment and control of the periodontal disease, an improvement in the symptoms of dyspepsia was reported.

Background: A common and tried-and-true ingredient in mouthwashes that works well against the development of plaque, gingivitis, and oral microbial growth is chlorhexidine gluconate (CHX). However, when it must be taken for an extended period of time, its benefits are limited by the accompanying side effects, which include taste modification, cytotoxicity, supragingival calculus formation, mucosal irritation, and tooth discoloration. In the 1980s, octenidine dihydrochloride (OCT), a new antibacterial cationic surfactant molecule, was produced at the Sterling-Winthrop Research Institute in Rensselaer, NY. OCT binds to negatively charged microbial surfaces and has a strong adherence to lipid components, which causes disruption of the cell membrane of bacteria, yeast, and fungus. Aim: The purpose of the study was to evaluate the efficacy of mouthwashes with 0.1% octenidine and 0.2% chlorhexidine in patients with gingivitis and periodontitis. Material and Method: Participants in this clinical experiment were split into two groups, each consisting of forty patients with periodontitis and gingivitis. Next, as an addition to scaling and root planning (SRP), 20 patients from each group were provided chlorhexidine mouthwash and 20 patients were recommended to use octenidine mouthwash. At baseline and three months later, clinical measures such as the O’Leary plaque index (PI), bleeding index, probing pocket depth (POD), and clinical attachment loss (CAL) were assessed. Result: All clinical measurements showed that the Octenidine group performed much better than the chlorhexidine group in both the gingivitis and periodontitis groups. Conclusion: When compared to chlorhexidine, Octenidine performed better across all of the previously listed clinical parameters. As a result, it can be regarded as a promising mouthwash for upcoming medical and scientific investigations.

Malocclusion is the world's third most common oral ailment. The fixed orthodontic procedure is now the most successful treatment strategy for malocclusion. Archwire bending is an important part of orthodontic therapy. However, because to the great stiffness and exceptional flexibility of orthodontic wire, it is a very difficult task. The old method of obtaining the created archwire curve is dependent on manual operation, which would bring various errors induced by human causes. Customised archwires are required in clinics for lingual orthodontics treatment. Previously, only expert orthodontists could physically bend these archwires. This is a pattern demands specialised skill training, precision, and extensive chairside time, but cannot guarantee the accuracy of appliances. So, what are the most recent developments?

Background: This study evaluated the efficacy of recombinant human bone morphogenetic protein-2 (rhBMP-2) in inducing de novo bone formation during the augmentation of the severely resorbed posterior maxilla for dental implant placement. Methods: Composite grafts consisting of rhBMP-2/absorbable collagen sponge (ACS) mixed with deproteinized bovine bone mineral (DBBM) Bio-Oss in a 1:1 ratio were used to reconstruct severely resorbed posterior maxillae in 13 patients (five men, eight women; age range: 50 to 66 years). Three patients were treated with sinus floor augmentation alone, and 10 patients with a combination of sinus floor augmentation and guided bone regeneration. A total of 71 dental implants were used in this study. The residual bone height below the maxillary sinus ranged from 0.5 to 3.0 mm. Clinical, radiological, and histomorphometric analyses were performed to assess the outcomes of bone augmentation. Results: The healing period was uneventful in all patients. The mean alveolar ridge height increased by 14 mm (range, 10–18 mm) and the mean alveolar width increased by 6 mm (range, 4–7 mm). Histopathological analysis revealed that newly formed bone was detectable throughout the implantation sites of sinus biopsies. The analysis of vascularization of the implant bed revealed large numbers of high-lumen vessels, in addition to moderate numbers of smaller blood vessels within the connective tissue. The histomorphometrical analysis of the tissue distribution showed that the amount of newly formed bone was 20.39 ± 4.95%, the amount of the remaining bone substitute was 41.85 ± 11.97%, and connective tissue was 37.76 ± 8.82%. The overall dental implant success and survival rates were 100% and remained unchanged at a follow-up period of 3 to 12 years. Conclusions: The results of this study demonstrated that a composite graft of rhBMP-2/ACS and DBBM can result in predictable reconstruction of a large bone volume of the maxilla for dental implant placement and functional loading.

Objective: The purpose of this work is to compare the incidence of dentinal defects in oval root canals with two different file systems and examine and contrast the creation of dentinal cracks using a scanning electron microscope (SEM) and a stereomicroscope during the root canal preparation process. Material and Method: Three groups of 15 were created from the sixty extracted human mandibular premolars: two were experimental and one was control. The experimental groups underwent root canal therapy. Group I the control group, did not receive any preparations. Group II is the Waldent walflex file and group III is the Trunatomy (TRN) file. After sectioning the roots at 3, 6, and 9 mm from the apex, the surfaces were examined with a stereomicroscope and SEM. Results: The data were examined using the Chi-square test. There were no fissures in the untreated group. The area between 3mm and 6mm was where the cracks in Waldent Walflex were most evident. There was no statistically significant difference between the experimental groups at either the 6 mm or 9 mm levels (P > 0.05). Conclusion: In conclusion, each rotary file utilized in the testing caused dentinal cracks. Compared to the Trunatomy file group, the Waldent walflex file group has more errors. The apical area of the samples had much more defects than the median and coronal regions.

The experimental groups underwent root canal therapy. Group I the control group, did not receive any preparations. Group II is the Waldent walflex file and group III is the Trunatomy (TRN) file. After sectioning the roots at 3, 6, and 9 mm from the apex, the surfaces were examined with a stereomicroscope and SEM. Results: The data were examined using the Chi-square test. There were no fissures in the untreated group. The area between 3mm and 6mm was where the cracks in Waldent Walflex were most evident. There was no statistically significant difference between the experimental groups at either the 6 mm or 9 mm levels (P > 0.05). Conclusion: In conclusion, each rotary file utilized in the testing caused dentinal cracks. Compared to the Trunatomy file group, the Waldent walflex file group has more errors. The apical area of the samples had much more defects than the median and coronal regions.","PeriodicalId":93501,"journal":{"name":"SVOA Dentistry","volume":" 24","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135290967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
