Abstract

Aims: The aim of the study is to determine the effects of different suturing techniques on post-operative complications (pain and swelling) following the removal of impacted lower wisdom teeth. Materials and Methods: Sixty medically fit patients were randomly selected with an age range between 16–42 years of both sexes. They were divided into 3 groups. These patients had impacted lower third molars indicated for surgical extraction. The first group comprised of twenty patients, the flap would be closed by simple interrupted suturing technique, and in the second group (20 patients) by vertical mattress suturing technique, and anchoring suture techniques for the third group (20 patients). All groups will be compared by clinical assessment to determine post-operative complications including pain and swelling. Results: In all treatment groups, pain (on VAS) reached its peak on the first post-operative day then faded away. In all groups, swelling was most severe in the first post-operative day and gradually decreased, with the anchor suturing technique showing significant difference of swelling at day three Conclusions: Changing the method of suturing appear to have no effect on the degree of pain, swelling following surgical removal of impacted mandibular third molars.

Abstract

Background: Mandible is one of the largest and strongest facial bones but there are some areas which are physicallyweak and fractured easily, i.e., angle and condyle. Recent studies demonstrated the correlation of the risk ofmandibular angle fractures to the presence of the mandibular third molars. The aim of the present study was toevaluate the mandibular angular cortical thickness in relation to the presence and eruption status of mandibularthird molar to verify if the mandibular third molar represent a risk factor for angle fracture or not.Materials and methods: The angular cortical thickness was measured using tracing elements and panoramicradiograph of 160 Iraqi subjects aged from (20-28) years, they were divided equally into four groups according to thestatus of mandibular third molar which were: Subjects with agenesis of mandibular third molar, subjects withcompletely erupted mandibular third molar, subjects with complete bony impacted mandibular third molar andsubjects with extracted mandibular third molar.Results: Subjects with agenesis registered the greatest value in the mean angular cortical thickness followed bysubjects with extracted, completely erupted and complete bony impacted mandibular third molar respectively.Extraction of mandibular third molar improved the angular cortical thickness and this effect had a strong positivelinear correlation with the extraction duration.Conclusion: The measurement of the angular cortical thickness was greatly affected by the presence and eruptionstatus of mandibular third molar, such measurements registered its highest values in subjects with third molar agenesisand its lowest values in subjects with complete bony impacted third molar.

Abstract

Back grounds and objectives: The aim of this study was to assess radiographically the angulations and depth of impacted mandibular third molars.Method: In a retrospective study 163 impacted mandibular third molars of 100 patients were examined on orthopantomograms (OPT) in the College of Dentistry/ Hawler Medical University during 2008. From these orthopantomograms the angulations (mesioangular, distoangular, vertical, and horizontal) and the depth (types A, B, and C) of the impacted mandibular third molars were recorded. The frequencies of unilateral and bilateral impaction were also recorded.Results: The average age of the patients was 26.5 + 5 ranging from 20-40 years with a median of 25 years. Fifty eight (58%) of the cases were female and 42 (42%) were male. The frequency of mesioangular, distoangular, vertical and horizontal impactions were 73 (44.8%), 37 (22.6%), 28 (17.2%), and 25(15.4%) successively. The depths of the impactions were 45 (27.6%) depth A, 74 (45.4%) depth B, and 44 (27%) depth C.The frequency of unilateral impaction was 26 (26%) and that of bilateral impaction was 74 (74%).Conclusion: Impacted mandibular third molars are more common in female. Mesioangular impaction is more common followed by distoangular. Depth B most common and most of the patients have bilateral impaction.

Abstract

The purpose of this study is to determine the incidence of impacted third molar and its distribution between the jaws among Mosul dental students, in addition to the study of its relationship with the family history, habit and sex of the patient. The incidence of congenital missing third molar and its distribution between the jaws were also estimated. The sample for this study consisted of 165 Mosul dental students; their age ranged from 20–25 years. The results revealed 46.06% of impaction third molar where the females show higher incidence of impaction than the males and in the mandibular arch than the maxillary one. Patients with chewing gum and singing habits show less degree of impacted third molar than those without these habits. A high significant correlation was observed between third molar impaction and family history of the patient. The study also revealed that the incidence of congenitally missing third molar was 12.57% and it is slightly higher in the maxilla than the mandible.

Abstract

The removal of impacted third molars is one of the most common procedures inoral surgery. This is because third molars show high incidence of impaction and areoften associated with pain due to pericoronitis.Assess the reasons for extraction and describe the type of tooth angulations andstate of eruption. Determine the association of selected factors with pericoronitis as areason for extraction.A total of 256 patients having symptomatic third molars and referred to the oralsurgery department for consultation, diagnosis and treatment of partially orcompletely impacted third molars in the mandible and maxilla were included in thesample. All these teeth were surgically treated.the most common cause of surgical extraction of third molars was pericoronitis(86.7%). The condition occurs mostly in mandible and in the 25-29 years age group.Horizontal/transverse third molars were more affected by pericoronitis (96.9%)followed by vertical angulations (91.6%). Pericoronitis encountered more frequentlywith complete soft tissue impaction (93.3%).pericoronitis was the most common cause of third molar extraction. Factorsassociated with increased risk of having pericoronitis include: age group 25-29 years,mandible location, Horizontal / transverse angulation type and complete soft tissueimpactions.

Abstract

Background: Predicting chronological age in adolescents and young adults can be crucial in Medico legal contextsand the third molar is the only developing tooth during this period that used to determine chronological age.The purpose of this study was to estimate the chronological age based on the stages of mandibular third-molardevelopment following the eight stages (A–H) method of Demirjian et alMaterials and methods: The sample consisted of 436 Iraqi adolescents and young adults subjects have been chosenwith known chronologic age (range, 14–24 years) and sex (162 males and 274 female), digital panoramicradiograph had been taken for each examined subject, Demirjian’s grading has been used to assess third molardevelopmentResults: Statistically significant differences (P _ 0.05) in third-molar development between males and females wererevealed regarding the development stages D,E and F. Third-molar genesis was attained earlier in males than infemales. Statistical analysis showed a strong correlation between age and third-molar development for males (r 2 _0.91) and for females (r 2 _ 0.87).Conclusion: It was concluded that the use of mandibular third molar development stages using Demirjian methodcan be considered as good valuable chronological age indicators in adolescents and young adults

Abstract

Background: Mandibular third molars are the most frequently impacted teeth in human and their surgical extractionhas become one of the commonest dentoalveolar surgeries. Accurate assessment of the position and morphologyof the mandibular third molars is necessary to make a sound decision about the proposed surgical procedure.Today, orthopantomography is the imaging method of choice to provide information for adequate assessment ofthe impacted lower third molars, the related teeth, anatomical features, and the surrounding bone. The aim of thisstudy is to determine the diagnostic accuracy of orthopantomographic view compared with postsurgical removalclinical finding in assessing the crown position, number and morphology of roots of the impacted lower third molar.Materials and methods: Total sample of 50 patients (25 males and 25 females), age range from 19 to 35 years oldwith impacted lower third molars assessed radiographically by using Standardized orthopantomography forevaluation of crown position and roots number and morphology in comparison with surgical findings.Results: According to the data obtained in this study, the comparison between the radiographic interpretation andthe clinical findings revealed a complete agreement for crown position (100% K- value) while based on roots numberthe (K –value was 0.7, 10.66, 0.80) for teeth with one, two and complex roots respectively and according to rootsmorphology (K –value was 0.64, 0.67, 0.81) for normal, fused and dilacerated roots respectively with more frequentfalse negative findingsConclusion: Although Orthopantomograph have a reasonable diagnostic value in the preoperative evaluation ofthe impacted lower third molars, but for more precise information modern radiographic modalities is advised to beused.

Abstract

The aim of the study is to assess the blood levels of (interleukin-6) at different intervals of time after surgical removal of impacted lower third molars.. Materials and Methods: The study group comprised 26 patients with impacted lower third molars .All extractions were performed under local anaesthesia using the inferior alveolar nerve block together with vestibular infiltration. A buccal full thickness two sided mucoperiosteal flap was raised. Sterile low-speed straight hand pieces and sterile distilled water were used for ostectomy. After tooth removal the wound was closed with 3-0 black silk suture. Three blood samples were drawn from each patient; one before the operation, the second 2hr. post operation and the third 24hr. post operation. The blood samples were collected through venipunc-ture, serum separated and stored in at -20ºC. Analysis was performed using the Enzyme linked Im-munosourbant assay ( ELISA). Results: The level of IL-6, in this study, showed an increase following surgery, in comparison with the level before operation. This increase in the level of Interleukin-6 re-mained high until 24hr after operation. Conclusion: Interleukin-6 (IL-6) is higher after surgical extrac-tion of lower third molars and remained with high levels to 24hr. after operation
