We present here a case of tissue destruction and paresthesia following the accidental injection of sodium hypochlorite instead of local anesthetic in a patient scheduled for endodontic procedure. The accident was managed by the local injection of steroid, debridement of necrotic tissue, daily dressings and medications. Wound healing was satisfactory at the end of 1 month. An extra-oral scar and a small area of paresthesia persisted even after 5 years. © 2011 Craniofacial Research Foundation.

Human saliva plays a vital role in maintaining the integrity of oral tissues and its composition changes during childhood due to maturation of the salivary glands thus indicating the need of age-matched controls for the clinical use of saliva as a diagnostic tool for diseases. Thus this study aims at analyzing physiologic variability of naturally occurring electrolytes in unstimulated whole saliva of children as a function of age. For this study unstimulated whole saliva specimens were collected from 20 healthy children equally divided into: Deciduous dentition (3-5 years) 5 males and 5 females and Mixed dentition (6-11) 5 males and 5 females. The samples were studied for estimation of electrolytes by inductively coupled plasma emission spectrometer. The electrolytes detected in this study were sodium, potassium, calcium and chlorine showing linear increase with age from deciduous to mixed dentition with potassium concentration highest in the mixed dentition group. Thus this study establishes a correlation between age and salivary composition. Hence constructing a comprehensive catalogue which is physiologic for salivary electrolytes with newer biochemical aids is necessary for saliva to serve as a diagnostic aid.

Aim: To determine the shear bond strength of self-etch adhesive G-bond on pre-etched enamel. Materials and methods: Thirty caries free human mandibular premolars extracted for orthodontic purpose were used for the study. Occlusal surfaces of all the teeth were flattened with diamond bur and a silicon carbide paper was used for surface smoothening. The thirty samples were randomly grouped into three groups. Three different etch systems were used for the composite build up: group 1 (G-bond self-etch adhesive system), group 2 (G-bond) and group 3 (Adper single bond). Light cured was applied for 10 seconds with a LED unit for composite buildup on the occlusal surface of each tooth with 8 millimeters (mm) in diameter and 3 mm in thickness. The specimens in each group were tested in shear mode using a knife-edge testing apparatus in a universal testing machine across head speed of 1 mm/ minute. Shear bond strength values in Mpa were calculated from the peak load at failure divided by the specimen surface area. The mean shear bond strength of all the groups were calculated and statistical analysis was carried out using one-way Analysis of Variance (ANOVA). Results: The mean bond strength of group 1 is 15.5 Mpa, group 2 is 19.5 Mpa and group 3 is 20.1 Mpa. Statistical analysis was carried out between the groups using one-way ANOVA. Group 1 showed statistically significant lower bond strength when compared to groups 2 and 3. No statistical significant difference between groups 2 and 3 (p < 0.05). Conclusion: Self-etch adhesive G-bond showed increase in shear bond strength on pre-etched enamel.

Pulmonary oedema following general anaesthesia or extubation is an uncommon and unpredictable clinical entity. This unusual disease is actually attributed to pulmonary and haemodynamic changes engendered by high negative intra-thoracic pressures during the state of obstructed respiration. We report a case of postoperative pulmonary oedema in a previously healthy 35-year-old female with post-extubation laryngospasm. The patient responded rapidly to conservative management including removal of secretions, re-intubation, oxygen therapy with positive pressure ventilation and administration of diuretics with short term antibiotics. This report emphasizes the importance of rapid identification and proper management of this serious condition. © 2010 Asian Association of Oral and Maxillofacial Surgeons.
