Background: Several studies showed that 4% articaine had greater tissue penetration than other anesthetics. Objectives: The current study aimed to compare the efficacy of buccal injection of local 4% articaine and 2% lidocaine on the numbness of palatal tissue. Materials andMethods: One hundred-ninety-six patients were randomly divided into two groups of 100. A group received 4% articaine and t...

Methods: Fat is harvested using disposable Caraway harvest cannula; processed with a bi-laminar filtration system and injected with disposable 18 gauge cannula. Intravenous clindamycin is given 1 hour before surgery and the intraoral mucosa at the site of injection is re-prepped with betadine. The upper lip is retracted and approximately 1–1.5 cm above and medial to the Stensen’s duct, the inje...

PURPOSE The purpose of this study was to evaluate the efficacy of a computerized anesthesia delivery system (e.g., Wand) compared to a traditional anesthesia administration, with respect to reducing disruptive pain related behavior during injections. METHODS Subjects consisted of 62 patients between the ages of 5 and 13 requiring local anesthesia for dental restorations in the maxilla. Patien...

Anesthesia of the soft and hard tissues of the maxilla may require up to 5 injections. Thus, the aim of this study was to evaluate the anesthetic efficacy of the anterior middle superior alveolar (AMSA) and supraperiosteal injection techniques during subgingival scaling and root planing (SRP). Thirty individuals with periodontitis were scheduled for SRP on the buccal aspect of teeth in the ante...

1. The paired cerebral giant cells (CGCs) of Lymnaea were studied using electrophysiological and anatomical techniques. 2. A strong electrotonic junction coupling the CGCs is located in the buccal ganglia, several millimetres distal to the cell bodies. This leads to 1:1 spike activity in the two cells. 3. The CGCs receive phasic and tonic inputs which appear to be common to the two cells. Two t...

Statement of the Problem Dental injection is one of the most fearful procedures in dental setting, especially for children. Many researchers have attempted to find a painless method. As computer controlled local anesthesia delivery system devices (CCLADs) allow the speed rate and pressure of injection solution to be controlled, they may cause less pain during injection in comparison to the conv...

A black tea product was evaluated for anti-mutagenic and in vivo anticancer effects. At concentrations of 1.25 and 2.5 mg/plate, black tea exhibited anti-mutagenicity with N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) in the Salmonella typhimurium TA100 strain. A Kunming (KM) mouse buccal mucosa cancer model was established by injecting mice with U14 squamous cell carcinoma cells. Following injec...

Many dentists prefer using smaller gauge (27- or 30-gauge) needles for anesthesia injection, believing that needles with a smaller diameter result in less injection pain than wider diameter needles. For this study, three dentists in a general practice administered 930 injections to 810 adult patients using 25- and 27-gauge needles for mandibular inferior alveolar block injections and 25-, 27-, ...
