Extraction of the lower third molar is one of the most common procedures performed in oral surgery. In general, impacted tooth extraction involves sectioning the tooth’s crown and roots. In order to divide the impacted tooth so that it can be extracted, high-speed air turbine drills are frequently used. However, complications related to air turbine drills may occur. In this report, we propose an alternative tooth sectioning method that obviates the need for air turbine drill use by using a low-speed straight handpiece and carbide bur. A 21-year-old female patient presented to the institute’s dental hospital complaining of symptoms localized to the left lower third molar tooth that were suggestive of impaction. After physical examination, tooth extraction of the impacted left lower third molar was proposed and the patient consented to the procedure. The crown was divided using a conventional straight low-speed handpiece and carbide bur. This carbide bur can easily cut through the enamel of crown. On post-operative day number five, suture was removed and the wound was extremely clear. This technique could minimise intra-operative time and reduce the morbidity associated with air turbine drill assisted lower third molar extraction.

The study is aimed at evaluating the effectiveness of phytoremediation in the management of oil impacted soil in Ekpan communities of Delta state, Nigeria. To do this, the study adopted an experimental research design that involve the use of phytoremediation (carpet grass Axonopus compressus) and nutsedge Cyperus rotundus) in the management of petroleum impacted soil site in Ekpan, This experiment spans for three months periods (one planting season). It involves the treatment of the oil impacted site with different plant species and soil amendments. Laboratory analysis of the soil samples was conducted to determine the effect of phytoremediation and soil amendments on hydrocarbon loss in oil impacted sites. The study revealed that the combined effect of Axonopus sp., Cyperus sp. and oil amendments accounted for 59% reduction in hydrocarbon. However Axonopus sp. and Cyperus sp. accounted for 47% and 48% reduction in hydrocarbon respectively. This shows that though, both plant species can be used successfully as a phytoremediation technique for the reclamation of oil impacted soils, but Axonopus sp. and Cyperus sp. was the most effective when applied with soil amendment (organic and inorganic manure). It is therefore recommended that iindigenous plant species (particularly Axonopus sp. and Cyperus sp.) should be used together with soil amendments in phytoremediation rather than the traditional bioremediation involving the use of microorganism. Oil companies operating in the Niger Delta region of Nigeria are encouraged not only to carry out physical clean-up of oil spills but should also carry out bioremediation to restore the environment back to its natural or near natural state. The methodology adopted in this study could be followed by oil companies to manage oil impacted soils in the Niger-Delta environment in Nigeria and indeed everywhere in the world.

Background: Despite scientific and technological developments on dentistry, man is still losing their teeth due to several reasons. Tooth loss may result in esthetical and functional discrepancies. Although beginning of dental transplantation is quite old, it started to take attraction on scientific basis recently. In recent years, oral implants are being used nearly in all fields of dentistry. Purpose: The purpose of this study was to evaluate 5 year follow-up of a patient with an impacted maxillary canine transplantation and a single-tooth implant. Materials and Methods: In our study an impacted canine was removed and transplanted immediately. Thereafter the missing premolar was replaced by an implant retained cemented crown. The patient was evaluated clinically and radiographically. Clinical periodontal parameters and implant mobility was evaluated, marginal bone level was measured on radiographs. Results: No significant changes have been observed in these parameters and implant mobility between year one and year five of the study. Conclusion: This study has demonstrated that stable long-term results can be achieved with replacement of single teeth with MIS Implant, and cemented crown on abutment with adjacent transplanted canine, with cumulative success rate for five years.

Aim of the study was to evaluate if there is a constant and significant reduction in traumaticity when mas- sively traumatic oral surgical procedures such as the removal of third molars are conducted with only ul- trasonic surgical devices (Piezotomes) expressed in a reduction of postsurgical pain and swelling on the patient’s side since such clinical experiences by the authors suggested this. Since oral surgeons criticize a higher time consumption for surgeries with Piezoto- mes also the objective time consumption was evalu- ated and compared to the traditional methods. Mate- rial and Methods: 56 female and male patients were selected that already underwent a removal of an im- pacted third mandibular molar on one side with rota- ry instruments by bone destructive burring with a still persisting comparable third mandibular molar on the contralateral side complaining about recur- rent pain episodes and were already documented for pain and swelling before. The ultrasonic surgical re- moval with the Piezotome was conducted with a buc- cal osteotomy of the compacta lateral to the impacted third molar, preservation of the resected compacta in saline solution, removal of the third molar by single or multiple dentotomy and full anatomical restitution of the surgical site with the preserved buccal com- pacta. The swelling was documented by kephalome- try 24/48/72 hours and 1 week post surgery, the pain index by the total consumption of ibuprofen-400 mg—tablets. Lesions of the mandible nerve were documented. Netto surgery time was taken from the first incision to the last suture of the procedure. Re-sults: 6 patients had to be excluded from evaluation due to incomplete post surgical follow up. A signify-cant (***, p > 0.999) decrease in pain and swelling of 50% was detected both for the parameters swelling and pain with Piezotome-surgery. No lesions of the mandible nerve were detected with Piezotome sur- gery whereas surgery with rotary instruments re- sulted in 16% hypesthe

Physicians under-report cases of child abuse or child maltreatment. We present a case of an impacted oesophageal foreign body in a physically abused child. S.H. is a 7-year-old male child who accidentally ingested metal clip while being assaulted by his paternal uncle whom he resides with. He presented with dysphagia, odynophagia and drooling of saliva and urgent x-ray soft tissue neck revealing the presence of the metallic foreign body in the prevertebral region. He had emergency oesophagoscopy with the removal of foreign body, did well and was discharged home 4th day postoperatively after parental counselling. It remains the responsibility of paediatric healthcare providers to consider child maltreatment as a differential diagnosis of any unexplained injury or medical problems, including oesophageal foreign body impaction.

This paper reports the case of K.Z, a 15 year-old child received in the Dental Surgery Unit of the Yalgado Ouédraogo Teaching Hospital for consultation for some aesthetic reasons due to dental retentions. On his X-ray, the premolars 25, 34, 35, 44, 45 and the molar 47 were deeply impacted, retained by supernumerary teeth. The treatment consisted in the removal of persistent temporary teeth and supernumerary teeth with poor radicular set, except one premolar. The removal of this premolar located between the roots of tooth 36, was source of major risk;therefore, it was put under clinical supervision. After these extractions, a fixed orthodontic appliance enabled bringing impacted teeth to a functional position. Orthodontic treatment lasted 3 years with a monthly check-up. Ours results are stable after one year of decline.

The study assessed the effectiveness of carpet grass (Axonopus compressus) in the phytoremediation management of oil impacted soil in Ubeji and Alesa Eleme communities of Niger Delta region of Nigeria. To achieve this, the study employed an experimental research design that involved the use of Axonopus compressus in the management of oil-impacted soil sites of Ubeji and Alesa Eleme. This experiment lasted for four months’ period (one planting season). Axonopus sp. was used for the treatment of the crude oil impacted sites. Laboratory analysis of the soil samples was conducted to determine the effect of phytoremediation on hydrocarbon, acidity, organic matter and moisture loss in oil impacted sites. The study revealed that the use of Axonopus sp. resulted in 66% loss of hydrocarbon from crude oil-impacted soils of Ubeji and Alesa Eleme. However, there is no significant difference in crude oil loss in the soils of Ubeji and Alesa Eleme as a result of Axonopus sp. This could be ascribed to the similarities in soil properties and climate type of the Niger Delta region of Nigeria. It also showed that the growth of Axonopus sp. in the crude oil-impacted soils of Ubeji and Alesa Eleme has reduced the acidity of hydrocarbon content in soils (4.46 - 6.87 pH in Ubeji and 4.66 - 6.86 pH in Alesa Eleme) from the first day to the 90th days of experiment, and thereafter there was stabilization at the 4th month. This indicates that acidity in soil increases (lower pH) with increase in the concentration of crude oil in soils. However, the adoption of Axonopus sp. in hydrocarbon-impacted soils has increased the pH of soils, and enhanced the accumulation of organic matter and moisture content in oil-impacted soils of Ubeji and Alesa Eleme. The implication of the findings is that Axonopus sp. has the tenacity to phytoremediate hydrocarbon concentration in soil effectively in any geographical region of the world;as such, it is recommended for adoption by oil companies, government and n

Subcutaneous emphysema is a condition that results from introduction of air into soft tissues. In head and neck, it is commonly observed following fractures of paranasal sinuses. Less frequently, it may occur during surgical procedures for tooth removal, when air from dental hand-pieces is forced into surgical site. Depending on its extension, it may involve vital spaces such as mediastinum. This specific finding may induce life-threatening situations. The aim of this article is to establish the incidence of subcutaneous emphysema among 10,779 impacted third molar surgical procedures and report the cases in which such complications had occurred. In this retrospective study, data collected from 10,779 third molar extraction procedures performed at Piracicaba School of Dentistry were evaluated for the occurrence of subcutaneous emphysema. Two cases of subcutaneous emphysema (0.018%) occurred following extraction of impacted third molars. Both were associated with mandibular tooth and related to the use of dental air hand-piece. One of the cases involved submandibular and buccal spaces while the other involved buccal and canine spaces. Regression of emphysema occurred spontaneously and postoperative recovery was uneventful. Subcutaneous emphysema following impacted third molar extractions is rare and strongly associated with the use of air turbines. Follow-up and preservation are the treatments of choice, but clinicians should be aware about the possibility of microbial spreading through facial spaces.
