Type I collagen fibers transmit forces, dissipate energy, and prevent mechanical failure in normal tissues. Mineralization of collagen fibers is proposed to strengthen these structural proteins as a possible therapeutic option for small tears in soft tissues such as cemental tears in periodontal ligaments. In the present study, collagen fascicles extracted from the tail tendons of male Sprague-Dawley rats were tested in a MiniMat tensile tester at different strain rates. The fascicles were previously immersed in SBF to induce mineralization and were maintained in a moist condition during mechanical testing. Mineralization of the fascicles resulted in an increase in the modulus of elasticity and tensile strength with minimal change in percentage elongation to failure. From SEM/EDS, calcium phosphate deposits formed on the fascicles indicating a high probability of intrafibrillar mineralization resulting in the observed improvement in mechanical properties.

Introduction: The myoepithelioma is a rare form of salivary glands tumors. The conservative surgery is the treatment of choice. Case Report: 49 years old male with a submucosa mass of the inferior lip with over 20 years of evolution without progressive growth, bleeding or pain. The patient had no risk factors except history of smoking (34 pack-years). At physical examination the patient presented a consistent submucosa mass of the inferior lip at the right, mobile, painless and without visual signs of abnormal mucosa over the mass. An excisional biopsy was performed and the piece had a reniform shape and rubberish consistency with 30 x16 mm dimension. The histology exam revealed a myoepithelioma of minor salivary gland. Discussion: Tumors with an exclusive constitution of myoepithelial cells are rare. The majority is located at parotid gland. Conclusion: Myoepithelioma of minor salivary glands are rare and the number of reported cases is limited. The differential diagnosis with pleomorphic adenoma is important.

Lipomas are the most frequent benign neoplasms of mesenchymal origin, and they mostly occur in various anatomical sites, including the palate, lip, buccal mucosa and vestibule, tongue, and floor of the mouth. Lipomas have a low incidence between 1 to 4% of benign oral cavity lesions. The clinical presentation of lipomas is generally characterized as a neoformation with well-demarcated borders. In this clinical case report, a 66-year-old female patient presented with pain and an inflamed region in the oral cavity. In intraoral clinical examination, a neoformation of 1 centimeter in diameter was observed and located in the jugal mucosa of the right side of the oral cavity. Furthermore, an excisional biopsy was chosen as the treatment method, and a postoperative histopathological study was conducted. Surgical excision is the treatment of choice for preventing recurrence in patients with oral lipomas.

Posterior quadrant of the maxilla consider as special challenges for use of implant active prostheses to restore dental function. Placement of Implant in the posterior part of maxilla influence hesitation due to the lack of sufficient alveolar bone height. This occurs due to the proximity of alveolar crest to the maxillary sinus because of sinus pneumatization, along with resorption of bone of the alveolar ridge secondary to tooth extraction, pathological lesion or trauma. Sinus lifting to augment atrophic maxillary posterior area to create space for implantation has been progressively widespread in latest years. In literatures 2 approaches have been designated for sinus lifting: the direct approach called also lateral approach and the indirect approach called also crestal approach.

Lichen planus is a chronic autoimmune multi-factorial inflammatory condition of the mucocutaneous skin that mainly interests the skin and oral mucosa. Oral Lichen Planus (OLP) affects 0.5 to 1% of the world's population and all human races equally. The factors that act as triggers of autoimmune processes and determine the appearance of OLP are represented by genetic predisposition, skin injuries, viral infections, contact allergies, and medications. OLP affects the oral mucosa and occurs frequently on the inside of the cheeks and less often on the edges of the tongue, gums, or lips. The condition is manifested by the appearance of painful erosions and mouth ulcers, accompanied by erythema and gingival scaling, and sometimes localized inflammation of the gums, near the amalgam fillings. There are 132 genes currently involved in the etiopathogenesis of OLP, but only a few appear to play a major role. These genes have been termed "leader genes". Thus, based on bioinformatics studies, the main genes involved in the pathogenesis of OPL are JUN, EGFR, FOS, IL2, and ITGB4. Although genetic status, immune system background, and infectious diseases are considered to be the most important incriminating and determining factors, the etiopathogenesis of OLP remains poorly known. Further genetic research is needed in order to achieve the generalizability of the findings and to strengthen the obtaining results.

Objectives: The study evaluated the bond strength, degree of conversion and fracture pattern of the hybrid layer in cement-dentin adhesion techniques. Materials and Methods: Bovine teeth dentin blocks were divided according to the cementation techniques: G1- Conventional three-step adhesive and dual-curing resin cement; G2- One-step self-etch adhesive and dual-curing resin cement; G3-Self-adhesive resin cement; and G4- Self-adhesive primer and dual-curing resin cement. Specimens were submitted to thermal cycling, chemical aging or water storage. Bond strength was evaluated by testing machine; fracture pattern observed by optical microscopy, and degree of conversion evaluated in micro-Raman spectrophotometer. Data were analyzed by two-way ANOVA and Tukey's test (α=0.05). Results: G1 showed greatest bond strength (p<0.001) followed by the G2 with higher values compared to G3 and G4, and no difference between them. For G2, G3 and G4, the thermal cycling affected the bond strength. The greatest degree of conversion was for G2 with Single Bond Universal, significantly higher than Scotchbond and RelyX U200. G4 provided highest value for the cement layer, and statistically higher than G1. G1 showed the highest strength than G3 associated to resin cement or self-adhesive resin cement. Different fracture patterns were observed. Conclusions: Aging methods reduced the bond strength. Degree of conversion was highest in the adhesive layer photo activated and in the cement layer with dual activation. Different fracture patterns were observed. Clinical Relevance: Resin cements degree of conversion and fracture pattern of the hybrid layer are relevant factors in the different bond strength values obtained in adhesive protocols.

The objective of this article is to review the keys for the correct placement of implants in the anterior sector of the maxilla in order to achieve long-term implant success and, since it is an anterior sector, correct aesthetics. There should be a distance of at least 1.5 mm between the tooth and the implant, and ideally, the minimum vestibular thickness of bone of the implant should be 2 mm. Between implants the mesio-distal distance should be 3 mm and regarding the apico-coronal we should have at least 3 mm from the margin of the implant to the future restoration. The case must be planned carefully and we have to decide: when to place the implant, the provisional restoration, the type of implant, requirement of a graft, etc.

Background: Pleomorphic adenoma is the most common benign tumour of the salivary glands with majority found in the parotid gland. It accounts for 3% of all head and neck tumours and 70-80% of benign salivary gland tumours. The clinical features depend on the size, location and in some cases the potential to undergo malignant transformation. They are usually solitary, unilateral, firm and mobile, painless and slow growing, hence the long duration before presentation for treatment. Purpose: To present an 84-year-old female who first presented 16 years ago with a 4-year history of bilateral swellings at the left and right parotid regions, measuring 8.0 cm by 10.0 cm and 3.0 cm by 5.0 cm respectively. Due to fear of surgery, the patient gave consent for the excision of only the left lesion whose histology report came out to be pleomorphic adenoma. The right swelling was left in-situ. The time lapse of 16years resulted in gradual increase in size of the right lesion now measuring 12.0 cm by 8.0 cm with no clinical symptoms but aesthetically unpleasant to patient. With consent, the right lesion was excised and pathological examination showed a benign lesion composed of ovoid and spindle-shaped epithelial cells arranged in sheets and ducts, some of which contain eosinophilia coagulum and cystic degeneration in other foci. No evidence of malignancy. No post-operative recurrence on the left side16 years after and on the right side 24 months after treatment Conclusion: Pleomorphic adenoma can grow to enormous size, and with a potential to undergo cystic degeneration if left untreated. Early presentation for treatment is of high importance to prevent complications associated with delay.
背景:多形性腺瘤是唾液腺最常见的良性肿瘤，多数发生在腮腺。它占所有头颈部肿瘤的3%和良性唾液腺肿瘤的70-80%。临床特征取决于大小，位置和在某些情况下进行恶性转化的可能性。它们通常是孤立的，单侧的，坚固且可移动，无痛且生长缓慢，因此在就诊前持续时间长。目的:报告一名84岁女性，16年前首次出现，左侧和右侧腮腺区肿胀4年，分别为8.0 cm × 10.0 cm和3.0 cm × 5.0 cm。由于害怕手术，患者只同意切除左侧病变，病理报告显示为多形性腺瘤。右侧肿胀未发生。16年的时间流逝导致右侧病变逐渐增大，现在尺寸为12.0 cm × 8.0 cm，无临床症状，但患者审美不愉快。经同意，切除右侧病变，病理检查显示良性病变，卵球形和梭形上皮细胞呈片状和管状排列，部分病灶含有嗜酸性粒细胞凝固和其他病灶的囊性变性。无恶性证据。左侧术后16年无复发，右侧术后24个月无复发。结论:多形性腺瘤可长至巨大，如不及时治疗，有发生囊性变性的可能。早期就诊对预防因延误引起的并发症非常重要。

Pyogenic granuloma of the oral cavity is a common, non-neoplastic, vascular tumor. The etiology is not clear and it is suggested to be attributed to different factors. It might be caused by a reaction to a stimulus such as trauma, viruses such as HSV-1, hormonal changes, as well as other factors such as tooth eruption or medication. Clinically it appears as a painless tumor that tends to bleed easily, with red color and rarely may be accompanied by a periodontal abscess and bone loss. Biopsy is the most common tool used for the diagnosis. Its treatment is usually surgical excision and lately the use of lasers for its excision has emerged. Special care should be given to pregnant women where the treatment varies. The aim of this review is to present the background of oral pyogenic granuloma and the case report presents the situation, histological image and treatment of an adult woman patient.

Methodology: The study was conducted from Oct to Dec 2021 after approval for ethical review board of Foundation university college of dentistry Ref no ( ). Patients undergoing various dental procedures were enrolled after written and verbal informed consent. Risk Stratification of each procedure was done applying novel risk assessment scoring system, according to the level of risk contact with saliva was given score 1, contact with blood scored as 2, production of aerosol (low level) through triple syringe was given score 3, high aerosol production by ultrasonic piezoelectric instruments was scored as 4. If the complete duration of the dental procedure was >60 min score assigned was 0.75, for procedures with 30 to 60 mins duration score specified was 0.50, if the duration of the procedure was less than 30 min score for that procedure was 0.25. For each patient total score of all these parameters was accumulated to grade risk of SARS -CoV-2 transmission as low (score <4), medium (score 4 to 6), or high (score >6) depending upon the accumulative score of each procedure. Results: Nine hundred and fifteen patients with a gender distribution of 163 (17.9%) males and 748 (82.1%) females with an age range < 18 – 45 years undergoing the dental procedure were enrolled. Out of 915, 436 (47.6%) procedures were found to be low risk, 38 (4.1%) moderate risk, and 437 (47.7%) high risk. Out of 174 maxillofacial procedures, only 18 (10.3%) were of high risk, similarly out of 113 orthodontics procedures, only 1 (0.9%) was of high risk and for 147 prosthodontic procedures, there were 55 (37.4%) high-risk procedures. On the other hand, for operative dentistry procedures (n=181), majority of 128 (70.7%) posed a high risk, among pediatrics procedures (n=92) there were 62 (67.4%) high-risk procedures and for periodontics (n=204) about 173 (84.8%) were of high-risk nature. Therefore, the majority of the high-risk procedures belonged to operative, pediatrics, and periodontics specialty as compared to other specialties (p<0.001). Conclusion: The majority of the high-risk dental procedures belonged to operative, pediatrics, and periodontics specialty as compared to other specialties.
