ABSTRACT

Introduction: Radiation therapy is commonly used in the treatment of head and neck cancer in both the definitive and postoperative settings. Proton therapy, due to its intrinsic physical properties, has the ability to reduce the integral dose delivered to the patients while maintaining highly conformal target coverage Materials and Methods:.A literature search was performed on scientific databases, and Preferred Reporting Items for Meta-Analyses guidelines were followed to compute results. Only original studies were selected. Selected studies were used to extract some proposed data for comparison, dosimetry, site, complications, and survival. Results: Proton beam therapy technology can be used against the conventional radiotherapy and shows satisfactory results. Yet conventional therapy is not less advantageous considering the amount of work available for any cross interpretations. Conclusion: Comparative preplanning could be beneficial considering multiple therapies for ruling out the best treatment outcomes that could be expected

ABSTRACT

Handheld X-ray devices are now offered in dental practice. Handheld X-ray units challenge the concept of a restricted access to the “controlled area” as they are held by the operator. Although an integral lead shield is provided, the distance from the body is variable, dependent on how the device is held. Currently, there are voluntary guidelines provided by the NCRP for dental radiation protection. Hand-Held portable X-ray devices are increasingly used for intraoral radiography.

ABSTRACT

Context: Temporomandibular joint disorders (TMDs) have been recognized as one of the most common causes of nondental orofacial pain. Various studies have been reported in literature regarding the relationship between prevalence of signs and symptoms of TMDs and gender, suggestive of female predilection; however, none of the studies have yet been reported to suggest the relationship between knowledge about temporomandibular joint (TMJ) and TMDs and self‑awareness of its signs and symptoms. Aim: To find a relationship between the level of knowledge about TMJ and TMDs and self‑awareness of its signs and symptoms. Settings and Design: This study was designed as an institutional survey. The study sample comprised 491 undergraduate and postgraduate (PG) students, consisting of 90 males and 401 females with age ranging between 18 and 32 years. Subjects and Methods: Two sets of questionnaire were distributed among the students. Statistical Analysis Used: Statistical analysis was performed with the help of Epi Info (TM) 3.5.3, descriptive statistical analysis, test of proportion, Chi‑square test, one‑way analysis of variance, Tukey’s test, and knowledge index. Results: It was observed that there was a gradual increase in the level of knowledge about TMJ and TMDs and self‑awareness of its signs and symptoms from the 1st year to PG students. Conclusions: A direct relationship exists between the level of knowledge about TMJ and TMDs and self‑awareness of its signs and symptoms.
