A case of actinomycosis occurring four years after the surgical removal of an impacted lower third molar is presented. The need for careful wound debridement and the use of antibiotics as a prophylactic measure is emphasized.
A case of an incomplete tooth fracture followed by a complete fracture was presented. The difficulty of diagnosing this condition was discussed as well as the possible histological explanation of the symptoms experienced by the patient. It once again points out to practising dentists, that whilst deep pockets can give rise to severe periodontal pain, intense and excruciating pain should be investigated with the cracked tooth in mind.
Although the patterns of dental disease is gradually changing, caries and periodontal disease still account for the most important reason for extractions in most countries. However their relative contributions towards overall tooth mortality figures varies. The aim of this study is to investigate the types of teeth usually associated with extractions due to caries or periodontal disease and its relation to the age at which the tooth was lost. The highest proportion of extractions due to caries occurred between 21 to 30 years of age while that for periodontal disease occurred between 41 to 50 years. For caries, the greatest proportion of extractions involved the posterior teeth. The most frequently extracted teeth due to caries are the molars, in particular the first permanent molar. However, for periodontal disease a slightly greater proportion of anterior teeth were lost than the posteriors. This trend is more marked in the lower jaw than the upper. Overall, extractions related to caries tend to increase posteriorly, while that for periodontal disease tend to increase anteriorly.
The reasons underlying the need for extraction of 2765 permanent teeth carried out over a 6 month period in the Out-patient Clinic in the Dental Faculty, University of Malaya, was investigated. The present study showed that dental caries (67.4%) is the leading cause for extraction followed by periodontal disease (19.6%). Caries accounted for the highest proportion of extractions up to the age of 50 whereas periodontal disease becomes the major factor beyond this age. The highest frequency of extractions carried out was between the ages of 21-30.
Matched MeSH terms: Tooth Extraction/statistics & numerical data
A total of 537 dentate adults from nine randomly selected government dental centers in three states in Malaysia were interviewed to assess their preference for either exodontia or preservation of teeth when they experience toothache, or have carious anterior or posterior teeth. The assumptions tested were i) patients prefer exodontia rather than preservation when they have toothache, and ii) patients are more willing to have posterior teeth extracted than anterior teeth for caries. Both these assumptions were rejected. Even though the majority of the subjects preferred preservation (59%) when having toothache, exodontia was the treatment of choice in a large proportion of subjects (41%). Significant differences in preference were found among the various ethnic, educational, income, and age groups. However, when ethnicity was held constant, binary regression indicated that the variations observed were determined by education, income, and age groups and not by ethnicity.
The results of the present investigation have shown the usefulness of suprofen in the control of pain following surgical removal of impacted wisdom tooth. The regime of 200 mg. q.d.s. orally, was shown to be satisfactory in the control of postoperative pain. Pain was rapidly controlled by the 1st hour after ingestion and subsequently maintained at a low profile until is was completely abolished by the 8th hour of the postoperative period.
The aims of this study were to determine the dental and periodontal status and the associated treatment needs, other than that for prosthetic care, in patients who requested removable partial dentures. Forty-six patients who had never worn removable partial dentures before were examined for plaque index, tooth status, gingival index, loss of periodontal attachment and tooth mobility. Prior to prosthetic treatment, 15% of the teeth needed conservative treatment and 1% needed extractions. From the periodontal point of view, 65% of the teeth needed some form of related therapy, and 2% of the teeth were at risk of extraction due to advanced mobility.
The palatal root of the first permanent molar is the most commonly deflected root into the maxillary sinus during extraction. A rational approach to the surgical removal of a root from the antrum is important. Some surgeons prefer the alveolar approach while others prefer the Caldwell-Luc operation. A case is presented where the palatal root tip of the left upper first molar was removed from the maxillary sinus by the Caldwell-Luc approach with simultaneous closure of the oro-antral fistula resulting from dental extraction. A fibreoptic light probe was used. The advantages and disadvantages as well as how to avoid the common complications of this surgical technique are discussed. A good result was achieved with successful removal of the root and no loss of sensibility of the teeth and/or gum for this case.
The maxillary tuberosity can fracture during extraction of a molar tooth. If a small bony fragment is affected, the extraction of the tooth and tuberosity continues; however, a conservative approach is advised if the bony fragment is large. In a modified blind surgical technique, the tooth is removed without the fractured bone.
Two children with Tetralogy of Fallot presented for dental extraction. Anaesthesia was induced rapidly and smoothly by inhalation of sevoflurane. We discussed the advantages of sevoflurane as an induction agent as compared to halothane in these children.
The aim of this retrospective study is to report on the prevalence of post-extraction complications among patients attending the Oral Surgery outpatient clinic of the Faculty of Dentistry, University of Malaya over a 12-month period from January to December, 1992. The prevalence of post-extraction complications which required further treatment was only 3.4% (n = 100), out of a total of 2968 patients who had extraction of one or more permanent teeth. Analysis based on complete clinical reports (n = 79) showed that dry socket accounted for nine out of ten cases of post-extraction complications. However the aetiology was largely unknown. No obvious association with medical history could be made. Lower teeth were more likely to have complications. The most common teeth associated with dry socket were the molars (76%) and premolars (19%). The most common molars to be affected are the first, followed by the third and lastly the second molars. A brief review of current aetiological factors of dry socket was discussed.
This study compares the use of inhalation sedation using sevoflurane (group S) with inhalation sedation using nitrous oxide (group N) in patients undergoing bilateral extraction of third molar teeth under local anaesthesia. The study was designed as a cross-over study. Seventeen ASA I, day surgery patients were studied. Patients were randomly allocated to receive either 8 l/min 50% nitrous oxide in oxygen (group N) or same flow of 1% sevoflurane (group S) for the first procedure. Each patient then had the alternate method of sedation for the second procedure. There were no significant differences between the methods in patient co-operation and surgeon's satisfaction with sedation. Psychomotor tests were comparable in both groups. The patients were significantly more sedated in the group S compared to group N (P=0.004). Significantly more patients complained of an unpleasant odour group S (P<0.01) but none withdrew from the study for this reason. No adverse cardiorespiratory effects resulted from sevoflurane or nitrous oxide sedation. Both methods gave good amnesia during the procedure. There was high acceptance of both methods and the patients rated the technique as equally satisfactory. We conclude that inhalation sedation with sevoflurane is a suitable alternative method to nitrous oxide sedation.
The aim of this study was to evaluate the morphological and biological properties of a locally produced "Bovine Bone Sponge" for use in dentistry. Bovine bone sponge was prepared from local calf bone. Endotoxin level and surface properties were investigated. The pore size and water uptake ability were measured and results were compared with the commercial haemostatic agent. The material was tested for its haemostatic property and its inhibition of alveolar bone resorption in a sheep model following dental extraction. Results revealed a significant difference in haemostatic effect, and a shorter bleeding time and a lower rate of alveolar bone resorption in bovine bone sponge compare to a commercial haemostatic agent.
