Management of symphysis fracture in a 3-year-old child with prefabricated acrylic splint and circum-mandibular wiring.

Pediatric mandibular fractures are often the sequelae of facial skeletal injuries in patients with trauma and frequently require hospitalization. Due to the retrusive mid-face position relative to the calvarial prominence, facial fractures are rare in children younger than 5 years of age. Although rare, they most often occur as a result of motor vehicle accidents.

Effect of various concentrations of sodium hypochlorite on primary dentin: an in vitro scanning electron microscopic study.

Background: Sodium hypochlorite solutions have been evaluated for their effects in bonding procedures as they are found to deplete or remove the organic portion of the dentin, particularly the collagen fibrils. The aim of this in vitro study was to assess and compare the efficacies of 1%, 2.5%, 5% and 10% NaOCl at 30, 60 and 120s on etched primary dentin.

Efficacy of a new interdental cleaning aid.

Background: It is now well established that removal of bacterial plaque can reduce the severity of chronic inflammatory periodontal disease. Periodontal disease is seen to progress faster interdentally and plaque control in these areas is of great importance. Various types of interdental cleaning aids have been developed in recent years.

Usefullness of palatal rugae patterns in establishing identity: Preliminary results from Bengaluru city, India.

Introduction: Palatal rugoscopy is the name given to the study of palatal rugae. Rugae pattern are widely considered to remain unchanged during an individual's lifetime. The rugae pattern has the potential to remain intact by virtue of their internal position in the head when most other anatomical structures are destroyed or burned.

Keratinization and its disorders.

Keratins are a diverse group of structural proteins that form the intermediate filament network responsible for maintaining the structural integrity of keratinocytes. In humans, there are around 30 keratin families divided into two groups, namely, acidic and basic keratins, which are arranged in pairs. They are expressed in a highly specific pattern related to the epithelial type and stage of cellular differentiation.

Effect of gene polymorphisms on periodontal diseases.

Periodontal diseases are inflammatory diseases of supporting structures of the tooth. It results in the destruction of the supporting structures and most of the destructive processes involved are host derived. The processes leading to destruction and regeneration of the destroyed tissues are of great interest to both researchers and clinicians.

Customised Bluegrass appliance reminder therapy. Report of two cases.

Background: Thumb sucking habits make up the majority of oral habits. While thumb sucking is considered normal during the first two years of life, if it is not controlled and persists beyond the preschool period it may cause deleterious effects on dentofacial structures. Reminder therapy using Bluegrass appliance has been proven successful to intercept thumb sucking habit.

Effect of periodontal therapy on pregnancy outcome in women affected by periodontitis.

Background: There is convincing evidence to suggest that infections affecting the mother during pregnancy may produce alterations in the normal cytokine- and hormone-regulated gestation, which could result in preterm labor, premature rupture of membranes, and preterm birth (PTB). Studies in the late 1990s associated periodontitis with preterm low birth weight (PLBW) deliveries, and this may have similar pathogenic mechanisms as other maternal infections. This study determined the effect of non-surgical periodontal therapy on pregnancy outcome.
