Abstract

The aim of this study was to assess the position ofimpacted lower third molars, the indications for extraction, and thepost-operative complications. Records of patients who attendedMaysan general hospital between March 2008 and April 2009 forsurgical removal of mandibular third molars. The angulation typeand depth of impaction were determined by reviewing theorthopantomograms. A total of 140 impacted teeth were surgicallyextracted from 132 patients (69 males, 63 females). The reasons forextraction include recurrent pericoronitis (55%) followed by caries(25%) and prophylactic purposes (20%). Mesioangular impactionsaccounted for (49.29 %) and Level 1 position of impactionaccounted for (65%) of extractions. 40 complications (28.57%),including persistent pain and swelling, infection, dry socket,Trismus and ulceration were reported. Persistent pain and swellingwas the most common complications followed by infection. Therewas no significant relationship between the angulation, level ofimpaction and the occurrence of complications. Mesioangular typeand Level A position of impaction were the most commonimpaction. Although the association was not significant, highfrequency of post-operative complications was observed inmesioangular, horizontal and levels a position of impaction.

Abstract

Early diagnosis of unerupted supernumerary teeth is veryimportant. Detailed examinations and evaluations of these teethwith Three-Dimensional (3D) images are very beneficial in termsof treatment planning and avoiding complications, which mayoccur. 3D imaging in Dentistry offers many advantages withrespect to diagnosis and treatment planning. The applications ofsoftware-3DCT images for detailed evaluation of impactedsupernumerary teeth: location, number, morphology and positionalarea, to avoid their possibility complications by early choosing theproper surgical treatment. A descriptive study including 98unerupted supernumerary teeth from 75 healthy patients between10 and 43 years of age. Reasons for patients attendance included :malocclusion ,lack of eruption of permanent teeth ,prominence ofgingival ,diastama, ,cystic lesion, caries and pain in differentregions of dental arches, taking into account the variables ofpersonal data, gender, age, location, morphology, number andpositional area, related complications,3DCT scans study andcorrelated with surgical approaches and treatment. Incidence inimpacted supernumerary teeth is higher among male patients (ratioM: F of 1.8:1) .They are most frequently located in the maxilla(64.28%) mainly in the premaxilla within the central incisors –mesiodens (40.82 %) were detected by 3DCTscans ,most of themclassified under Type III ( 72.5%). Most cases present only singleunerupted supernumerary teeth (77.33%). The conical shape isthe commonest morphology (34.69%).The diastema registered thegreatest proportion (40.81%) of complications cases .Surgicalremoval of these teeth was done by labial or buccal approaches in(45.91%) of cases. 3DCT radiographies achieved to diagnosisand determine the exact situations, identified morphology,determined number presented and determined the position types ofwhole impacted supernumerary teeth that they were provedsurgically to be in the same locations, similar shapes, right numberand correct anatomical positions. With less invasive surgicalinterventions and less operation time. Early treatment planning ofthe impacted supernumerary teeth, the exact diagnosis ofanatomical location, shape, number, position of mentioned teeth isan important issue to avoid their complication in the future.

Abstract

This study focused on the clinical evaluation of naproxen and ibuprofen efficacy on pain, swelling and trismus after surgical removal of impacted mandibular third molar, whether they used only pre–operatively or pre– and post–operatively. The number of patients included in the present study was 40, divided into four groups: Each group is 10 patients, the first group received naproxen as sodium 1hour pre-operatively followed by three times daily for five days post–operatively. Whereas the second group received naproxen as sodium three times daily for five days begins 1hour post–operatively. However, the third group had been given ibuprofen 1hour pre–operatively followed by three times daily for five days post– operatively. The fourth group administered ibuprofen three times daily for five days begins 1hour post–operatively. The pain was evaluated by the number of paracetamol tablets taken by the patients recorded on the pocket chart, whereas the swelling was measured subjectively. The trismus was evaluated by measuring the maximum mouth opening between the incisal edges of the maxillary and mandi-bular central incisors using the graduated vernier. The results showed that the use of naproxen as sodium 1hour pre–operatively minimized the pain, swelling and trismus significantly compared to ibuprofen.

Abstract

Backgrounds: Maxillary canine impaction is complicated and time consuming to treat, for being highly diverse in inclination and location; it may be a companied by root resorption of the neighboring teeth. CBCT has been used for its' diagnostic reliability in localization of impacted canine and revealing its' serious local complications.Objectives: Localization of maxillary impacted canine using cone beam computed tomography for assessment of angulation, distance from occlusal plane, alveolar width and proximity to adjacent teeth.Subjects and Methods: The study sample was 33 subjects 16 females and 17 males attended to Al-Wasitti general hospital in Baghdad city-Oral and maxillofacial radiology department for CBCT scan investigationfrom November/2015 to April/2016. By using theCS 9000 device, 3D images and coronal, axial and sagittal views obtained to perform the selected measurements.Results: Contact of impacted canine to the nearby teeth had a strong effect on their root resorption. Vertical or horizontal angulation measurement in axial view, was not possible for a number of cases.Comparison of the angulation measurement validity between axial and coronal views, had showed an obvious statistical difference in coronal view for vertical angulation, and in the axial view for horizontal angulation calculation. Correlation of the canine localizations found in the study with the measurements, showed a significant statistical difference with age and vertical angulation (coronal view). Age or gender correlation with the measurements wasnon significant statistically, except for age with vertical angulation (coronal view).Conclusion: utilization of CBCT provides a worthy data about the impacted maxillary canine localization, for more explanation and treatment of these cases surgically and by orthodontics.

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 purpose of this study is to ascertain whether the upper and lower third molars can contribute to the occurrence or aggravation of crowding. The sample of this study consisted of 187 subjects (103 males and 84 females) aged 20–30 years, then the sample was divided into two main groups and three subgroups. The groups consisted of crowded and normal subjects. The subgroups consisted of persons who had maxillary or mandibular third molars that were either impacted, erupted into function or agenesis. The results showed that the crowded group revealed a higher percentage of impacted third molar and a smaller percentage of erupted third molar particularly in the mandible and a smaller percentage of third molar agenesis than the normal group. The females had more impacted third molar in the upper and lower jaws for both crowded and normal groups. The percentage of third molar agenesis in the males was higher in the upper jaw and smaller in the lower jaw than the females. In normal group, no significant difference was found between upper and lower jaws except in females where the unilateral third molar agenesis was greater in the lower jaw. In crowded group, the lower jaw revealed a higher percentage of impacted third molar for all subjects and a smaller percentage of erupted third molar for females and a smaller third molar agenesis for the males as compared with upper jaw.

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.
