Comparative study of two needle models in terms of deflection during inferior alveolar nerve block.

Objectives: The purpose of this study is to determine the possible differences in deflection between two needles of same length and external gauge but with different internal gauges during truncal block of the inferior alveolar nerve. The initial working hypothesis was that greater deflection may be expected with larger internal gauge needles.

Study Design: Four clinicians subjected 346 patients to inferior alveolar nerve block and infiltrating anesthesia of the buccal nerve trajectory for the surgical or conventional extraction of the lower third molar.

Comparison of two needle models in terms of bevel deformation during truncal block of the inferior alveolar nerve.

Objectives: To evaluate the differences in terms of bevel deformation between two types of needle of the same length and external caliber, but with different internal diameters, during truncal block of the inferior alveolar nerve.

Study Design: Four operators performed truncal block of the inferior alveolar nerve and infiltrating anesthesia of the buccal nerve for the extraction of a lower third molar in 266 patients. The truncal block was carried out using a standard 27G x 35 mm needle with an internal caliber of 0.

Removal of hyperplastic lesions of the oral cavity. A retrospective study of 128 cases.

Aims: Based on our accumulated experience, the present study evaluates and discusses the indications, advantages and inconveniences of oral cavity epulis resection using the carbon dioxide laser (CO2) versus the Erbium:YAG laser (Er:YAG), diode laser and surgical scalpel.

Material And Methods: A retrospective study has been made of 120 patients involving the removal of 128 epulis lesions with the CO2 laser, Er:YAG laser, diode laser and surgical scalpel. Postoperative controls were carried out after 7, 15 and 30 days to evaluate healing and wound evolution, and after 3, 6 and 12 months to assess possible relapse.

Evaluation and comparison of 2 needle models in terms of blood aspiration during truncal block of the inferior alveolar nerve.

Purpose: We conducted a study to determine the possible differences in blood aspiration between 2 needles of the same length and external gauge but with different internal gauges during truncal block of the inferior alveolar nerve. The working hypothesis was that increased blood aspiration may be expected with larger internal gauge needles.

Materials And Methods: Four clinicians subjected 346 patients to inferior alveolar nerve block and infiltrating anesthesia of the buccal nerve trajectory for the surgical or conventional extraction of the lower third molar.
