Aim: To evaluate the effect of applying a matrix metalloproteinase (MMP) inhibitor on the fracture resistance of root-filled teeth restored with Everstick fiber-reinforced composite resin.

Subjects And Methods: After the selection of 60 freshly extracted human mandibular first molar, root canal access and standard uniformly sized mesio-occluso-distal (MOD) cavities were made and the teeth were randomly assigned into three groups ( = 20 each): Group I, the MOD cavity was first lined with flowable composite resin and then restored with composite resin. In Group II, Everstick fiber was placed into the bed of flowable composite in buccal-pulpal-lingual direction before the composite restoration was placed.

Background: H19, a 2.3 kb lncRNA, has been linked to tumor metastasis and progression, but its significance in oral squamous cell carcinoma (OSCC) remains unclear. H19 was initially thought to have a tumor-suppressive function, but recent studies have shown that it possesses both tumor-promoting and suppressive functions.

Deficiency of peri-implant tissue contours is commonly seen due to the process of alveolar ridge resorption after tooth loss. Minor deficiencies can be effectively managed by soft-tissue augmentation procedures to create a more biomimetic tissue contour. The minimally invasive roll technique is a modification of the palatal roll-flap technique and can be carried out at both stages of implant surgery.

Estimation of Blood Loss in Patients Undergoing Surgery for Oral Malignancies: a Clinical Study.

J Maxillofac Oral Surg

October 2024

Department of Plastic Surgery, SDM College of Medical Sciences and Hospital, Shri Dharmasthala Manjunatheswara University, Dharwad, Karnataka 580009 India.

Article Synopsis
  • The study aimed to estimate blood loss and blood transfusion rates following major surgeries, including neck dissections and reconstructions, while exploring blood conservation strategies.
  • Data was collected from 38 patients, primarily males with oral squamous cell carcinoma, from 2017-2019, showing an average blood loss of 673.5 ml and a significant correlation between surgery duration and blood loss.
  • The findings suggest that successful blood conservation methods led to avoiding transfusions in 76.3% of patients, though there's no standardized method for accurately measuring blood loss.

Article Synopsis
  • Oral verrucous lesions (OVLs) are challenging to diagnose due to varying histopathological features, and this study investigates Mcm-2 and Ki-67 as markers to help differentiate these lesions from oral squamous cell carcinoma (OSCC).
  • Using 90 paraffin-embedded tissue samples, the researchers assessed the expression levels of Mcm-2 and Ki-67, alongside patient survival data, employing statistical methods for analysis.
  • Findings revealed that Mcm-2 is a more sensitive and prognostic indicator than Ki-67, with higher overexpression in verrucous lesions and improved survival rates in verrucous squamous cell carcinoma (VSCC) compared to conventional OSCC, suggesting its potential for better diagnosis

Background: It is a well-recognized fact that abnormal cell proliferation plays a crucial role in the development of odontogenic lesions. p53 is a tumour-suppressor gene which assists in cell cycle regulation and p63 is a homolog of p53 responsible for ectodermal differentiation and maintenance of stratified epithelial progenitor-cell. Analysing the tissue expression of p53 and p63 in odontogenic lesions may provide us with an insight into their potential role in the development of these lesions.

Context: The antimicrobial potential of conventional medicaments is reduced due to their limited permeability. The use of calcium hydroxide (CH) is known to reduce the root strength. Nano intracanal medicaments have the following advantages over conventional such as higher surface area and chemical reactivity, and due to its nanosize, have better penetrability, supporting its possible use as an intracanal medicament.

Background: Premature loss of primary teeth results in space loss, thus affecting the integrity of the oral tissues. According to the American Academy of Pediatric Dentistry, the treatment for a carious primary molar with pulpal involvement is pulpectomy. The success of this procedure depends on the elimination of bacteria, the most common being , by cleaning and shaping the root canals with rotary or hand instrumentation.

Department of Oral and Maxillofacial Surgery, SDM Craniofacial Surgery and Research Centre, SDM College of Dental Sciences and Hospital, A Constituent Unit of Shri Dharmasthala Manjunatheshwara University, Sattur, Dharwad, Karnataka, India.

Background: Ablative procedures of the oral cavity require composite removal of tissues, which results in compromise of both functional activities and esthetic mutilation and proves to be a reconstructive challenge. This paper focuses on the reliability and versatility of a single perforator-based anterolateral thigh (ALT) flap in oral cancer reconstruction.

Materials And Methods: All patients who underwent reconstruction with a single perforator-based ALT for oral cancer defects at our center were included in the study.

Introduction: India introduced the Cigarettes and Other Tobacco Products Act (COTPA) (Packaging and Labeling [P and L]) Rules in 2008. These rules utilize the tobacco package to communicate tobacco-caused harms; it also seeks to restrict the delivery of misleading information about the product on the pack. The enormous burden of tobacco-related oral cancers in India necessitates the compliance with the law regarding presentation of information in powerful and salient ways, intentionally designed to increase the awareness in target individuals.

Rough surfaces of dental implants, when exposed to the oral environment, are conducive to biofilm colonization and can predispose the affected implant to periimplantitis. Recession coverage using soft-tissue grafts is one of the treatment modalities used for the treatment of exposed implant threads. Recession coverage on the palatal aspect of maxillary implants is difficult due to the firm nature of the palatal mucosa and, consequently has not been widely documented in the literature.

Background: The COVID-19 pandemic has created an unprecedented situation which the treatment of maxillofacial trauma, especially mandibular fractures that were previously managed using general anaesthesia had to be performed under local anaesthesia. In these cases, there was a requirement for an anaesthetic agent that would have a rapid onset but also provide a prolonged effect. The aim of the study was to evaluate the onset, duration, depth, required volume of anaesthesia of lidocaine with epinephrine versus combination of lidocaine and bupivacaine with epinephrine anaesthetic agents in surgical management of isolated mandibular fracture patients.

July 2023

Department of Pediatric and Preventive Dentistry, Government Dental College and Research Institute, Bengaluru, Karnataka, India.

Facial development involves an intricate regulatory mechanism that accounts for numerous craniofacial abnormalities, common being orofacial clefts. Although cleft in the secondary palate accounts for one-third of orofacial clefts stills remains an under-researched domain. Hence, in this work, the authors put forth two non-syndromic, asymptomatic cleft uvulae reported among bimodal male patients of the Indian-Asiatic population who came up for dental screening.

The study evaluated expression profiles of few regulatory lncRNAs in oral squamous cell carcinoma and normal mucosa adjacent to oral cancer using paired fresh frozen and formalin-fixed paraffin-embedded (FFPE) tissues stored at a different duration of time (1-5 years) using real-time quantitative PCR. The quantity and quality of total RNA isolated from FFPE tissues was less compared with that of fresh frozen tissues, which resulted in a noncorrelation of quantification cycle values. Following normalization, the expression of lncRNAs in the paired tissues did not differ significantly.
