Abstract

ABSTRACTAims The periodontal ligament injection in isolated areas of the mandible was clinically evaluated us-ing only a conventional dental cartridge syringe. Materials and Methods: One hundred subjects requir-ing extractions of either premolars or molars participated in the study. Results: A high percentage of success rate (85%) was achieved but with unfavorable comment from the patient in regard to a painful injection. Duration of surgical anesthesia following the injection proved to be adequate in almost all extractions performed. Conclusions: New devices for performing this injection appear to have some advantage over the conventional syringe technique. However, these devices were unfortunately unavail-able at the area of study. Further studies are recommended to further evaluate its success and also to determine the response of both the periodontal ligament and pulpal tissue in cases were restorative treatment of teeth is to be undertaken for example crowns, bridges and fillings

Abstract

Aims: To compare three maxillary nerve block techniques of local anesthesia in terms of success dur-ing minor oral surgical procedures on maxillary teeth. Materials and Methods: The clinical trial was conducted at the Department of Oral and Maxillofacial Surgery/ College of Dentistry/ Mosul Universi-ty. The subjects enrolled in the trial required surgical procedures on their upper anterior and / posterior teeth. The sample included 60 subjects who were divided into three groups of 20 each; Group I (control I) patients who were to receive the posterior superior alveolar nerve block technique. Group II (control II) patients who were to receive the infraorbital nerve block technique and Group III (control III) pa-tients who were to receive the maxillary nerve block technique of local anesthesia. For comparison, the following variables were recorded for the three techniques: Positive aspiration, onset of adequate surgi-cal anesthesia and pain grade scale during surgical procedure. Results: In regard to positive aspiration before injection of solution, the results showed no significant difference regarding positive aspiration among the three techniques. For onset of adequate surgical anesthesia, the results disclosed no signifi-cance difference in mean duration of onset of anesthesia among the three groups. In regard to pain ex-perienced during the surgical procedure , no significant difference was recorded among the three groups. Conclusions: The maxillary nerve block technique via the high tuberosity approach seems to be a safe and effective technique for achieving anesthesia of the hemimaxilla as long as there is strict adherence to the anatomical landmarks and approach described. The technique carries with it a high success rate and with specific applications can allow the dentist to provide painless dental treatment

Abstract

Aims: A clinical trial was carried out to assess the efficiency of a single buccal injection to achieve
anesthesia of the buccal aspect of the upper first molar instead of the traditional two injections. Materials
and Methods: The subjects included in the clinical assessment were those needing extraction of
an upper first molar of either side. For the purpose of comparison, the sample was randomly divided
into two main groups: Group I (control group) which included 100 subjects who were to receive two
buccal injections and a single palatal injection before extraction. While Group II (trial group) included
100 subjects who were to receive a single buccal injection and a single palatal injection before extraction.
The following data were recorded: Pain on needle insertion, pain on deposition of solution, onset
of surgical anesthesia and adequate surgical anesthesia. Results: The first criterion recorded was pain
on needle insertion where the results showed no significant difference between both groups. The
second criterion was pain on deposition of solution. Here the results also showed no significant difference
between both groups in this aspect. For onset of surgical anesthesia, no significant difference was
shown between both groups. In regard to pain grade experienced during surgery for both groups, the
results showed that grade A anesthesia was recorded in 95% of patients in group I , whereas in 93% of
patients in group II. Grade B anesthesia was recorded in 5% of patients in group I and in 7% of patients
in group II. Statistically speaking, no significant difference was disclosed in regard to pain assessed
during the extraction of the tooth between both groups. Conclusions: The achievement of successful
local anesthesia is a continual challenge in dentistry. Any suggested new approach for achieving adequate
anesthesia for either the maxilla or mandible as long as it is safe and effective can be recommended
for routine dental care.

Abstract

Aims: To evaluate the effect of local irrigation with tranexamic acid in minimizing post–operativebleeding following the removal of impacted lower wisdom teeth. Materials and Methods: This clinicaltrial was conducted at the Department of Oral and Maxillofacial Surgery / College of Dentistry / Universityof Mosul. The sample recruited comprised twenty healthy subjects who required surgical removalof clinically as well as radiographically evident impacted lower wisdom teeth. The sample wassubdivided into two groups of ten subjects each. The first group which is the control group included tensubjects where after removal of the tooth, local irrigation of socket was carried out with normal saline.The second group which is the trial group comprised ten subjects also, but in which tranexamic acid(injectable solution) in diluted form was used for local irrigation of socket. Both solutions were of equalamount. Estimation of amount of blood loss immediately following surgery was the criterion for comparisonand was based on weight of gauze used before and after application over extraction socket. Results:The results showed a statistically significant decrease in the amount of blood loss in the trialgroup when compared with the control group. Conclusions: Tranexamic acid as commercially availableor freshly prepared oral rinse may be used as an aid for the reduction or prevention of postoperativebleeding following the removal of third molars in healthy subjects as well as in patients with bleedingproblems.

Abstract

Aspiration is an important and highly recommended step before giving a local anesthetic solution In this regard, a survey involving (50) dentists were requested to fill in a special form specifically designed for this purpose. The results showed that the majority of dentists (90%) do not routinely perform aspiration before giving a local anesthetic solution for one or more reasons.

Abstract

A painless approach to the well known painful palatal injection using topical application of pressure is described. Seventy dental patients requiring anesthesia of the palatal tissue (soft and hard) for:surgical procedures were chosen for the study. A highly significant value (p>0.01) of a painless injection was noticed when the ipsilateral side was compared with the contralateral side in the same patient. Further studies on this approach are recommended to further evaluate its success.

Abstract

Aims: To assess the effect of alkalization of local anesthetic solution for the purpose of enhancing itsefficiency in periapical surgery. Materials and Methods: A total sample of 80 patients, all needingperiapical surgery on one or more of their upper anterior tooth (teeth) was subjected to this trial. For thepurpose of comparison, the sample was randomly divided into two groups based on the local anestheticsolution that they were to receive before surgery. The first group(control) included those patients whoreceived the commercially available local anesthetic solution with a standard pH of 3.5.The secondgroup (trial group) included those patients who received a pH adjusted local anesthetic solution at 7.2(using sodium bicarbonate).Prior to, and at the completion of intended surgery, the following datawere recorded: Pain during injection, onset of achievement of surgical anesthesia, pain duringoperation and the duration of operation itself. Results: A significant difference in regard to onset ofachievement of surgical anesthesia between both groups was noticed with a faster onset in group two where the patients received a pH adjusted local anesthetic solution when compared to control group where the patients received the commercially available local anesthetic solution. Also, less pain on deposition of solution was noticed in the second group as well as less pain score levels were recorded during operation in regard to the same group. Conclusion: The pH adjusted local anesthetic solutionsmay provide certain advantages when compared to the commercially available local anesthetic solutions regarding enhancement of anesthetic efficiency, reduced pain on injection as well as during surgery.

Abstract

Four different materials were used to assess their activities to control blood oozing. A surprising result showed that chlorhexidine(2%) has good haemostatic activity beside gel foam. Local anesthesia showed haemostatic activity for short time, while no effect of normal saline on blood oozing during operation. Further studies on this approach are recommended for further evaluation of haemostatic activity of chlorhexidine.
