Background: In Pakistan, many people undergo tooth extractions every year due to various causes such as dental caries, periodontitis, and trauma. For a healthy alveolar bone after tooth extraction, some kind of intervention is always required. Honey can possibly help to improve bone healing after tooth extractions. Aim: To observe the effects of honey on bone healing of alveolar sockets after tooth extraction in humans. Method: It was an experimental study, conducted at Lahore general hospital over the period of 6 months. Twenty-four participants were included in the study through simple random sampling technique. After tooth extractions in both groups, honey was injected into extracted sockets of the experimental group while the control group was left as it was. Levels of BMP-2 were tested in saliva through the ELISA technique on days 1, 3, and 7 of tooth extraction. Results: In the control group, mean BMP-2 levels were 485.5± 52.63, 623.7 ±47.16 and 692.5± 11.86 while in the experimental group the mean values of BMP-2 were 494.3 ± 49.89, 703.6 ± 39.31 and 812.9 ± 34.40 at day 1, 3 and 7 respectively. The mean difference was calculated to be 8.75, 79.9, and 120.5. A significant difference (p-value <0.001) was noted in levels of BMP-2 between the experimental and control group on days 3 and 7. Conclusion: Raise in levels of BMP-2 in the experimental group when compared with the control group confirmed better bone healing. Hence, honey can be used to promote bone healing in post-extraction tooth sockets. This study can be used in future to improve bone quality and minimize ridge resorption after tooth extractions.

The purpose of this study was to evaluate the biological response of a bone substitute material placed around Ti dental implants surgically positioned in tooth extraction sites of canine mandible. Under general anesthesia six adult mongrel canine had bilateral extractions of the fourth premolarbicuspid. Each extraction site was modeled into a 4 wall defect with box-like dimensions (1.0 mm vertically x 1.2 mm horizontally x 0.75 mm laterally). Utilizing the Branemark technique, screwtype implants with healing screws (10 mm x 4 mm), were placed in the prepared sites. A synthetic hydroxyapatite bone cement (HAC) [BoneSource®, Howmedica Laboratories, Inc.] was prepared and filled in around each implant. As controls, three canine had HAC placed in prepared sites without implants. Prior to periodontal flap suture closure a n-butyl-2-cyanoacrylate biodegradable tissue adhesive [Histoacryl®], was placed over implants and HAC. One canine each was euthanized at one month (m), two m, and three m postop.

Endodontic treatment aims at eliminating microorganisms from root canal systems. The resistance of these microorganisms contributes for the permanence of the apical lesion, leading to the failure of treatment. The microbiological factor is pointed out as the major cause of failures after intervention. In these cases, root canal retreatment can be performed aims the re-instrumentation, cleaning, and new filling in the root canal. Also, retreatment treatment can be associated with a parendodontic surgery in the attempt to reverse failure without a tooth extraction. The objective of this clinical case is to report a root canal retreatment associated with apical surgery with one year follow-up in the lower central incisor’s region. It was concluded that paraendodontic surgery is an effective and conservative treatment option compared to tooth extractions, and when properly performed, with the aid of good materials such a MTA, brings satisfactory results by returning normal conditions to the periodontal tissue, as well as health and function to the teeth affected by the inflammatory process.

<p>Third molar surgery is the most common minor oral surgical procedure performed in dental clinics. Displacement of maxillary third molar tooth into adjacent spaces such as infratemporal fossa, maxillary sinus has been reported earlier. We present an unusual case of iatrogenic displacement of maxillary third molar into pterygomandibular space. A 24 year old dental undergraduate reported to Department of Oral surgery with complaints of trismus and swelling in the check region after unsuccessful attempt at extraction of maxillary right third molar tooth. Computed tomography scan localized the tooth in the pterygomandibular space. A surgical removal of the displaced tooth was performed under general anesthesia. Displaced tooth was approached by an intraoral vertical incision along the anterior border of ramus of mandible. Correlating with computed tomography scan, tooth was located and removed followed by suturing of the surgical site. A good knowledge of the operating area and adjoining spaces is essential to avoid iatrogenic damage to tissues during minor oral surgery procedures. Adequate exposure and appropriate instrumentation during surgery can prevent undue complications and ensure quality patient care.</p>
