Comparative Evaluation of Marginal Integrity of Three Esthetic Restorative Materials - An In-vitro Study.

CONTEXT: Microleakage is the major cause for the failure of dental restorations, especially in Class V cavities, as margins of such restorations are generally located in dentin or cementum. Microleakage evaluation is necessary as a means of evaluation of the marginal integrity of restorative materials. This would assist in developing techniques and materials that would reduce damage caused by the failure of the restorative marginal seal. AIM: The aim of this study is to analyze and compare the marginal integrity among three esthetic restorative materials, namely GC Fuji II LC, GC G-Aenial anterior composite resin, and GC Equia forte fil. SETTING AND DESIGN: Sixty orthodontically extracted caries-free premolar teeth with Class V restorations were divided into three groups. Microleakage was measured using an ordinal scale of 0-4, as given by Khera and Chan, in increasing order of dye penetration, which was observed under a microscope. MATERIALS AND METHODS: Study was conducted in sound human extracted premolars in which Standardized Class V cavities were prepared. Teeth were randomly and equally assigned to three groups (GC Fuji II LC, GC G-Aenial anterior composite resin, and GC Equia forte fil). Teeth were sectioned longitudinally into two halves using diamond discs and the sectioned halves of the teeth were evaluated for dye penetration under stereomicroscope. STATISTICAL ANALYSIS USED: Intergroup comparison of mean dye penetration scores were compared using the Kruskal-Wallis test along with post hoc pairwise comparison by Mann Whitney U test. The level of statistical significance was set at 0.05. RESULTS AND CONCLUSION: All the three groups (GC Fuji II LC, GC G-Aenial anterior composite resin, and GC Equia forte fil) tested showed microleakage at the tooth restoration interface. It was evident that microleakage was found to be highest with the Fuji II LC, both at occlusal and cervical levels. GC Equia forte exhibited the best performance in limiting microleakage around the restoration margins.

Mindful awareness for female dental students through yoga, motivational video, and a combination of two on stress reduction.

OBJECTIVE: Assessment of the potential effect of yoga, motivational videos, and a combination of two on stress reduction in female dental students. METHODS: The current study design is a nonrandomized trial carried out among female dental students (n = 120). The selected subjects were allocated into three groups, namely, group A: yoga group assigned under a professional yoga instructor, group B: motivational video group, and group C: a combination of two (A and B) involving yoga sessions and motivational videos; following which formative examinations were carried out at 6 weeks which were referred to as stressor 1 and those carried out at 12 weeks were referred to as stressor 2. Using Spielberger's State-Trait Anxiety Inventory for Adults (STAI-A) recordings were measured at baseline, stressor 1, and stressor 2. RESULTS: There was a significant decrease in trait anxiety scores at both stressors in all the groups with a significant reduction in depression score from stressor 1 to 2 in group 1 and group 3 subjects. The significant decrease occurred in STAI-A scores in group 1 and group 3 subjects at both stressors (P < 0.001) with no change observed in group 2 subjects. CONCLUSION: The present study is one of a kind and positively correlates yoga and motivational videos with stress reduction. Both of these interventions proved to be beneficiary for physical as well as mental health of study subjects.

Antibiotic prescriptions in pediatric dentistry: A review.

Most commonly prescribed drugs in pediatric dentistry are "Antibiotics." Among Dentists, there is a trend toward overuse of antibiotics for nonindicated clinical conditions. This insufficient knowledge of the appropriate clinical indications for antibiotic prescriptions promotes the overuse of antibiotics and contributes to the emergence of antibiotic resistance among children. According to the various surveys done on the dental students, dentists and pediatric dentists on the antibiotic prescribing practices, overall, adherence to the professional clinical guidelines was low. There was a wide variation in dosages for all the antibiotics prescribed and for prolonged periods which were inconsistent with the recommendations. This paper reviews the current literature from the year 2000 to 2019. An electronic literature search was conducted in MEDLINE/PubMed, EBSCO host, and Google Scholar databases. The data was also collected manually from comprehensive textbooks. Some recommendations were also based on the opinion of experienced researchers and clinicians. Thus, this review aims at highlighting clinical indications, dosages, and duration of therapeutic antibiotic prescriptions for orofacial infections in the pediatric outpatients and at the same time creating an awareness, regarding the necessity of strictly adhering to the clinical guidelines for antibiotic prescriptions.

Restoring esthetics after anterior tooth loss for a five-year-old child: natural tooth pontic fiber reinforced prosthesis.

The loss of anterior teeth can be hurtful to the patient both psychologically and socially. As the children are becoming more aware these days, they have also become conscious about their looks. Early loss of deciduous anterior teeth has a psychological effect on many children. In such young patients, paper replacement of the teeth can minimize these concerns. Many approaches have been described for this temporary replacement. This article describes the technique to use extracted natural teeth as pontics bonded to adjacent teeth with fiber reinforced resin. A fiber reinforced temporary replacement of missing teeth provides adequate strength and esthetic requirements in such cases.

Rehabilitation after surgical treatment for retinoblastoma: ocular prosthesis for a 6-month-old child.

Maxillofacial prosthetic (MFP) rehabilitation can be especially challenging in a young, precooperative, or behaviorally compromised child presenting with an enucleated eye. Retinoblastoma is the most common intraocular malignancy in childhood and is one of the most common pediatric cancers. Treatment consists of enucleation (or removal of the entire globe) followed by placement of orbital implants. Unrestored anopthalmic sockets exhibit growth retardation and can lead to facial disfigurement. This report describes the challenges faced during rehabilitation of a 6-month-old girl with an anophthalmic socket due to enucleation for retinoblastoma. The objective of the MFP team was to provide a custom-built, acrylic ocular prosthesis in as comfortable and atraumatic manner as possible. The case was a success and underscores the value of a multidisciplinary dental approach for the treatment of children with very special needs.
