Randomized Controlled Trial Comparative Study Clinical TrialAnesthetic efficacy of unilateral and bilateral inferior alveolar nerve blocks to determine cross innervation in anterior teeth.
The purpose of this prospective randomized study was to measure the degree of anesthesia obtained with unilateral and bilateral inferior alveolar nerve blocks to determine whether cross innervation occurs in anterior teeth. ⋯ Cross innervation does seem to occur in mandibular central and lateral incisors. However, the success rates in these teeth with bilateral inferior alveolar nerve blocks were below 75%. The failure of the inferior alveolar nerve blocks to anesthetize the anterior teeth was the overriding reason for failure. Clinically, bilateral inferior alveolar nerve blocks to provide profound pulpal anesthesia in mandibular anterior teeth are not recommended on the basis of the results of this study.

Randomized Controlled Trial Clinical TrialHemodynamic assessment of local anesthetic administration by laser Doppler flowmetry.
The hemodynamic effects of local anesthetic administration with and without a vasoconstrictor were compared by using laser Doppler flowmetry. ⋯ This investigation has confirmed the sensitivity of laser Doppler flowmetry as an investigational tool for assessing hemodynamic changes associated with anxiety and the administration of local anesthesia.

Randomized Controlled Trial Clinical TrialAnesthetic efficacy of ropivacaine in maxillary anterior infiltration.
The purpose of this prospective, randomized double-blind study was to evaluate and compare the anesthetic efficacy of 0.5% ropivacaine with 1:200,000 epinephrine, of 0.5% ropivacaine, and of 0.5% bupivacaine with 1:200,000 epinephrine in maxillary lateral incisor infiltrations. ⋯ We concluded that 0.5% ropivacaine with 1:200,000 epinephrine was equivalent to 0.5% bupivacaine with 1:200,000 epinephrine in pharmacologic action. The duration of pulpal anesthesia was less for ropivacaine without epinephrine. Ropivacaine with epinephrine has the potential to replace bupivacaine with epinephrine in clinical dental practice because of the decreased potential for cardiac and central nervous system toxicity.

Clinical Trial Controlled Clinical TrialValidity of clinical diagnostic criteria for temporomandibular disorders: clinical versus magnetic resonance imaging diagnosis of temporomandibular joint internal derangement and osteoarthrosis.
Research is needed to assess the validity of clinical decision criteria for the diagnoses of temporomandibular disorders. The objective of this study was to assess the reliability of clinical diagnoses in predicting magnetic resonance imaging diagnoses of temporomandibular joint internal derangement and osteoarthrosis in a patient pain group with temporomandibular disorders. ⋯ The classification system of the Clinical Diagnostic Criteria for Temporomandibular Disorders provides insufficient reliability for determination of the presence of temporomandibular joint internal derangement and osteoarthrosis. It should be supplemented by evidence from cross-sectional and longitudinal investigations to assess decisive differences in the areas of pathogenesis, treatment, and prognosis.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of methods for measuring root and mucogingival sensitivity.
The aim of this study was to compare the variability of measurements of root and mucogingival sensitivity over a 24-hour period. ⋯ Calibrated cold stimulation of root areas appears to provide the most sensitive measure to assess therapeutic interventions to control cervical dental pain because of low intrasubject variability in untreated patients.
