Internal root resorption is an unusual condition of a tooth when the dentin and pulpal walls begin to resorb centrally within the root canal. A case of internal resorption with buccal perforation was found in a maxillary central incisor. As there was extensive lesion and continuous exudation, envelope flap surgery was suggested. The apical third was obturated with gutta-percha, and the perforated lesion was repaired with mineral trioxide aggregate. Thermo plasticized gutta-percha was filled in the residual canal space and composite resin was used to restore the coronal cavity. The symptoms and signs ceased, and the results were satisfactory at 2-year follow-up.

Oral submucous fibrosis (OSMF) is an insidious chronic progressive disease of the oral cavity which is considered as a precancerous condition. The suggested aetiological factor is the practice of certain customs/habits of the inhabitants of South East Asia. As the disease progresses, the oral mucosa becomes stiff due to the formation of fibrotic bands in the cheek, ultimately leading to reduced mouth opening and trismus. The early form of the disease can be treated by medicinal means, however, advance form needs surgical excision of the fibrotic tissue bands. The defect created due to the excision needs to be repaired by various grafts including split thickness skin grafting, bilateral nasolabial flaps, palatal island flaps, tongue flaps, buccal fat pad graft and temporalis muscle flap graft. We present the management of trismus following OSMF by various surgical approaches in three cases.

BACKGROUND: Grip strength is widely accepted as an indicator of maximum hand strength and contraction of active muscles of the hand and forearm. OBJECTIVE: The aim of this study was to assess the effects of forearm posture (pronation, supination and neutral) and anthropometric variation on MVC grip strength and grip endurance time in young university adults. METHODS: Fifty healthy, right-handed men volunteered to participate in this study. The experiment was characterized by measuring MVC grip strength and endurance time of 50% MVC randomly in three different postures (supine, pronation and neutral). Performance was assessed in terms of dependent variables: MVC grip strength and grip endurance time. RESULTS: MANCOVA results showed no significant effect of posture on MVC grip strength ([Formula: see text]) and grip endurance time ([Formula: see text]). There was a significant effect of age ([Formula: see text]), height ([Formula: see text]) and forearm length ([Formula: see text]) on the grip endurance time in supine position. However, palm circumference had a significant effect on MVC grip strength ([Formula: see text]) in pronation posture only. The pronation forearm posture produces 7.4% more grip strength than a supine posture. In addition, the grip endurance time was improved in the supine position, compared to the neutral and pronation forearm posture. CONCLUSIONS: This study showed that the MVC grip strength is affected by the weight and palm circumference. In addition, palm circumference was the most influential factor affecting grip strength. Thus, anthropometric and posture-specific grip strength data are essential for clinical and industrial applications. The results can be used to prepare guidelines for rehabilitation, health care, sport and medicine.

Acquired immunodeficiency syndrome (AIDS) is caused by human immunodeficiency virus (HIV). The pathologic hallmark of AIDS is severe immunosuppression; HIV infected infants and children suffer considerable morbidity and mortality. In addition to the catastrophic medical consequences, HIV infected infants and children along with their families suffer tremendous psychological upheaval owing to this chronic, often devastating illness. Because of the complexity and vast clinical spectrum of HIV infection, this article is limited to a general review of the pediatric HIV manifestations and management.
