Assessment of pencil beam scanning proton therapy beam delivery accuracy through machine learning and log file analysis.

Purpose: Comprehensive Quality Assurance (QA) protocols are necessary for complex beam delivery systems like Pencil Beam Scanning (PBS) proton therapy. This study focuses on automating the evaluation of beam delivery accuracy using irradiation log files and machine learning (ML) models.

Methods: Irradiation log files of 935 clinical treatment fields and routine QA beams were analysed to evaluate spot parameters and Monitor Unit (MU) accuracy.

An artificial neural network based approach for predicting the proton beam spot dosimetric characteristics of a pencil beam scanning technique.

Utilising Machine Learning (ML) models to predict dosimetric parameters in pencil beam scanning proton therapy presents a promising and practical approach. The study developed Artificial Neural Network (ANN) models to predict proton beam spot size and relative positional errors using 9000 proton spot data. The irradiation log files as input variables and corresponding scintillation detector measurements as the label values.

Myths and misconceptions in general public toward ocular complications followed by the removal of upper teeth.

Introduction: The upper jaw forms the floor of the maxillary sinus and the upper teeth are continuous with the whole midface and cranium, therefore while treating these teeth, it is important for the practitioner to consider the possibility of ocular complications. Ocular disturbances such as blurring of vision, mydriasis, ptosis, diplopia, enophthalmos, miosis, and blindness are rare complications due to intraoral local anesthesia. So far at present, the general population is having myths and misconceptions regarding the extraction of teeth and vision loss; hence, we evaluated the same.

Knowledge, awareness, and practices of complementary and alternative medicine for oral health-care management among dental students.

Objective: The objective of this study is to assess the awareness and practices of complementary and alternative medicine (CAM) for oral health-care management among dental students.

Materials And Methods: A cross-sectional study was conducted in 200 dental students of final year and internship selected by simple random sampling using a close-ended questionnaire.

Results: Among the total respondents, 52% were females and 48% were males.

Facial Palsy, a Disorder Belonging to Influential Neurological Dynasty: Review of Literature.

Facial paralysis is one of the common problem leading to facial deformation. Bell's palsy (BP) is defined as a lower motor neuron palsy of acute onset and idiopathic origin. BP is regarded as a benign common neurological disorder of unknown cause.

Evaluation of dose perturbation at the interface of two different density medium using GAFCHROMIC film EBT2 and Monte Carlo code EGSnrc for Co-60 beam.

Introduction: Accurate dosimetry at the interface of two different density medium (e.g., air cavity in the head and neck cancers and lungs in thoracic region) is a major cause of concern in external beam radiation therapy.

Microbial colonization and their relation with potential cofactors in patients with denture stomatitis.

Aim: To determine microbial prevalence in the mucous membrane and prosthesis of denture wearers with and without denture stomatitis and to study its relationship with potential clinical cofactors.

Materials And Methods: Saliva was collected from 200 patients (100 female and 100 male) wearing dental prosthesis for measurement of pH. Oral samples of the mucous membrane and of dentures were taken with sterile swab for microbiological analysis.

In vitro caries-preventive effect of fluoridated orthodontic resins against cariogenic challenge stimulation.

Aim: The aim of the present study was to evaluate the in vitro caries preventive effect of fluoridated orthodontic resins under pH cycling with two types of acid demineralizing saliva.

Materials And Methods: Brackets were bonded to 120 extracted human premolars, using Rely-a-bond (n = 40), Tru- Bond (n = 40) and Ortho-one (n = 40) orthodontic bonding agents. Each group of resin was divided into 2 subgroups (n = 20): immersion in remineralizing artificial saliva for 14 days and acid saliva with pH 4.

Antimicrobial activity of commercially available essential oils against Streptococcus mutans.

Introduction: Many essential oils have been advocated for use in complementary medicine for bacterial and fungal infections. However, few of the many claims of therapeutic efficacy have been validated adequately by either in vitro testing or in vivo clinical trials.

Objective: To study the antibacterial activity of nine commercially available essential oils against Streptococcus mutans in vitro and to compare the antibacterial activity between each material.
