Calcium hydroxide dressings using different preparation and application modes: density and dissolution by simulated tissue pressure.

Aim: To study the effect of different apical shapes in prepared simulated root canals on the application of a commercially prepared calcium hydroxide paste by a syringe or lentulo spiral.

Methodology: Three different types of root canal preparation were performed in 90 simulated canals: group A to an apical size 20 and a 0.10 taper using hand and rotary instruments, group B to an apical size 30 and a 0.

Sinusitis as a source of dental pain.

Sinusitis is a common medical problem that can occasionally manifest as dental pain. If the patient is experiencing dental pain in the maxillary posterior teeth, then it is appropriate for the dentist to rule out sinusitis as a source of the problem before proceeding with definitive dental treatment. Often there is an obvious odontogenic source of the pain, and this should be resolved first, but in other situations it is difficult to determine the cause of the symptoms.

The efficacy of reservoirs in bleaching trays.

Comparison of MMPI scores with self-report of sleep disturbance and bruxism in the facial pain population.

Sleep disturbance and bruxism are common clinical characteristics of the chronic facial pain patient. Previous studies have shown that chronic pain patients reporting disturbed sleep show more psychopathology and respond less readily to treatment. Bruxism has been linked to emotional stress and periods of difficult life change.

Lateralization of chronic facial pain: fact or fiction.

Previous studies have shown that pain is generally reported more on the left side of the body. It has been hypothesized that patient report of left pain dominance may be due to the right hemisphere being less efficient in processing cutaneous sensory input while being dominant for emotional experience as compared with the left hemisphere of the brain. Only in cases of trigeminal neuralgia has self-report of pain been lateralized to the right side.
