Purpose:
Bone remodelling of the cranium determines the enlargement of the maxillary sinus. The process involves the resorption of the internal walls of the maxillary sinus minutely exceeding the ...growth of maxilla. During this process, there is bone deposition taking place at the medial border of the nasal cavity, and simultaneous resorption of the lateral wall of the nasal cavity. There are very few studies which depict the correlation of the growth of the maxillary sinus with that of changes in the dimensions of the nasal aperture. Therefore, the present study was undertaken to determine, compare and correlate the three- dimensional morphometric parameters of the maxillary sinus and nasal aperture in Karnataka and Kerala population, to utilize the data for the purpose of individual identification, sexual dimorphism or any other application in the field of forensic facial reconstruction and /or human identification.
Materials and Methodology:
This pilot study has been carried out by morphometric measurements between the Craniometric landmarks of the maxillary sinus and nasal aperture of 30 subjects, aged between 18 to 30 years.
Results: Morphometric parameters of maxillary sinus and nasal aperture were seen to be statistically significant in few groups on comparision which can be applies for sexual dimorphism.
Conclusion:
Maxillary sinuses have been reported to stay intact even though the skull and other bones of the cranium may be severely disfigured in victims who are incinerated or during external trauma. These morphometric measurements of maxillary sinus like the width, the depth, and the height which aid to investigate the accuracy and reliability of maxillary sinuses can also be used for sex estimation. These dimensions can be correlated with the measurements of the nasal aperture and this will also give an insight into the development of the cranium. These measurements are also important anthropometric parameters for classifying the race and sex of the individual whose identity is unknown.
This research assessed the efficiencies of aloe vera, 0.1% triamcinolone acetonide, and 5% amlexanox in the management of OLP.
A total of 120 participants diagnosed with oral lichen planus (OLP) were ...equally divided into three groups and treated with: aloe vera, (Group A), 0.1% triamcinolone acetonide (Group B), and 5% amlexanox (Group C) topical medicaments. The patients were evaluated for pain, using the visual analogue scale (VAS). They were also evaluated for ulcerative lesion type and erosive area on days 1, 7, and 15 of the study.
There was a statistically considerable decrease in the VAS pain scale score, reduction in the erosive area on buccal mucosa, and healing of ulcer from day 1
to 15
day with all three tested drugs.
All drugs used in this study; aloe vera, triamcinolone acetonide, and amlexanox were effective in treating OLP patients.
Introduction: Maintenance of crestal bone level is crucial for the success of implant-supported prosthetic rehabilitation. Implant neck design plays an important role in maintaining crestal bone ...levels. The microring neck design is known to counteract the marginal bone loss and improving bone-to-implant contact by providing optimal load distribution as reported by the finite element studies and animal studies. Aim: The current study aimed to evaluate dental implants’ short-term (12 months) clinical and radiographic parameters in periodontally healthy patients versus those with history of treated periodontitis. Materials and Methods: The current prospective interventional study was performed at AB Shetty Memorial Institute of Dental Sciences, Mangalore, Karnataka, India from 2016 to 2018. In the study, 24 microthreaded implants were placed in periodontally healthy patients (group A, n=12) and patients with a history of treated periodontitis (group B, n=12). Peri-implant radiographic crestal bone loss, clinical measurements like probing pocket depths, bleeding on probing, and soft tissue complications were assessed around implants at time of implant loading, and 3, 6, and 12 months postloading. Statistical Package for the Social Sciences (SPSS) software version 22 was used for statistical analysis. Statistical significance was set at p<0.05. Results: At the end of one-year postloading, peri-implant crestal mean bone loss of 2.317±0.914 mm (mesial), 2.37±1.276 mm (distal) and 2.673±1.178 (mesial), 2.87±1.075 (distal) mm were observed in groups A and B, respectively. The probing pocket depths were 3.729±0.95 mm and 4.017±0.67 mm in groups A and B, respectively at the end of the study period. However, there was no statistical significance for probing depths among both groups. At the end of the study period, soft tissue complications were 16.67% in group B, while no complications were noted in group A. None of the groups showed any technical or mechanical complications. Conclusion: The results of the study revealed that crestal bone loss and pocket depths around implants are similar in both groups at various follow up periods. However, the incidence of peri-implant soft tissue complications is higher in patients with history of treated periodontitis.
The present study was conducted to assess stress distribution around dental implants based on the all-on-four treatment concept. The finite element analysis (FEA) models comprised cancellous bone ...covered with cortical bone. Four dental implants were placed in two different designs. In model 1, the four implants were placed parallel to each other, whereas, in model 2, the all-on-four concept was followed. The vertical and lateral loads of various values were applied, and stress was evaluated. In model 2, the least stress was observed in both lateral and vertical loading in the peri-implant region. The all-on-four concept proved to be beneficial in reducing the stress around dental implants, thereby reducing the treatment cost.
The association of the linear dimensions of the inferior turbinate hypertrophy with nasal septal deviation has been studied recently. However, the volumetric dimensions provide a more accurate status ...of the turbinate hypertrophy compared to linear measurements. The aim of this study was to analyze the association of inferior nasal turbinate volume with the degree of nasal septal deviation (NSD).
A retrospective evaluation of the cone beam computed tomography (CBCT) scans of 412 patients was carried out to obtain 150 scans which were included in the study. The scans were categorized into three groups. Group 1 comprised of 50 scans of patients with no inferior turbinate hypertrophy (ITH) and no nasal septal deviation. Group 2 comprised of 50 scans of patients with ITH and no NSD; whereas Group 3 included 50 scans of patients with ITH and NSD. The total turbinate volume of inferior turbinates (bilateral) were determined by using Vesalius 3D software (PS-Medtech, Amsterdam, Netherlands).
The intraclass correlation coefficient (ICC) between the volumetric estimations performed by the two radiologists was 0.82. There were no significant age and gender related changes in the total turbinate volume. Patients in Group 3 had significantly higher (
= 0.001) total turbinate volume compared to Group 2 and Group 1. There was a positive and significant correlation (r = 0.52,
= 0.002) between the degree of septal deviation and total turbinate volume. When the total turbinate volume of the patients with different types of septal deviation was compared in Group 3, a statistically significant difference (
= 0.001) was observed. Regression analysis revealed that the septal deviation angle (SDA) (
= 0.001) had a relationship with total turbinate volume. From the results of the study we can conclude that the total turbinate volume is higher in patients with nasal septal deviation. It can also be concluded that the septal deviation angle has a positive correlation with total turbinate volume. The data obtained from the study can be useful in post-surgical follow up and evaluation of patients with nasal septal deviation and hypertrophied inferior nasal turbinate.
Recent advent of immune checkpoint inhibitors (ICIs) have made significant improvement in the treatment outcome of cancer patients. They are also known to increase the overall survival in many ...malignancies. They target key immune checkpoints, acting on the cytotoxic T-lymphocyte antigen-4, programmed death-1 (PD-1), and PD-1 ligand 1 pathways. ICIs are effective in cancer therapy, but also possess various adverse effects that are termed together as immune-related adverse events (irAEs). Information focusing only on the oral reactions of irAEs is scanty in the literature. Therefore, we performed a computerized database search in PubMed and Google Scholar to identify and collect data regarding the oral adverse effects of ICIs. The early recognition of oral irAEs and appropriative intervention may help in improving the quality of life in patients. This paper presents a brief review of oral irAEs and their management.
Cleidocranial dysplasia (CCD) is a
rare inherited disorder affecting dental and skeletal tissues. CCD usually has
an autosomal dominant pattern of inheritance and common clinical features seen
are ...aplastic or hypoplastic clavicles, late closure of fontanelle, open skull
sutures, retained deciduous teeth, late eruption of permanent teeth and
presence of multiple impacted supernumerary teeth. Here, we present a case of
CCD in a female patient with positive family history. The diagnosis was
confirmed clinically and radiographically. The newer radiographic advancement,
CBCT was used to validate the radiographic findings.
Novel betacoronavirus is a recent threat to the global health. It has been identified as the cause of the outbreak of respiratory illness that originated in the city of Wuhan, China and has spread ...rapidly to several other countries within a short span of time. Transmission occurs through respiratory droplets or contaminated surfaces from an infected person, saliva of infected persons has also shown shedding of live virus. Clinical manifestations of COVID-19 can range from mild to severe and can even progress to ARDS and septic shock leading to death. All health care professionals including dental surgeons are at a high risk of acquiring the infection. Dental clinics and hospitals carry a high risk of cross-infection. Aggressive preventive and personal protective measures help in preventing exposure to the infection. Dental professionals should adopt various specific preventive methods and treatment strategies to prevent the spread of the infection in a dental setup.
Salivary calculus or sialolithiasis is a disease that affects the salivary glands characterized by the formation of mineralized structures within the glandular substance or excretory ducts of the ...salivary gland. The formation of these salivary stones is due to the crystallization of minerals in saliva. It causes blockage of salivary ducts and results in painful inflammation or sialadenitis of the salivary gland. Among the salivary glands submandibular gland has highest incidence of sialolithiasis due its anatomic features. The patient commonly experiences pain and/or edema when the ducts are obstructed. The case report presented here is of sialolithiasis of submandibular gland which had caused pain and swelling in the floor of the mouth.
Pyogenic granuloma is a non-neoplastic reactive growth commonly found in the oral cavity and skin. It is benign in origin and may arise due to factors like trauma, local minor irritation and an ...imbalance in the levels of hormones. Oral pyogenic granuloma occurs commonly in young females in second decade of their life possibly due to hormonal influences leading to changes in the vascular system. Oral pyogenic granuloma presents itself as a smooth or lobulated growth, mostly pedunculated but occasionally with a sessile growth. The colour of pyogenic granuloma may vary from pink, red and purple and this variation in colour is related to the age of the lesion. Clinically the most common site for oral pyogenic granuloma is gingiva, lips, tongue and buccal mucosa. This report presents a unique location for oral pyogenic granuloma at incisive papilla. Palatal pyogenic granuloma is rarely reported.
