Alveolar osteitis (AO) is the most common postoperative complication following a tooth extraction. This article focuses on its etiology and contributing factors. It is intended to assist the general practitioner in reducing the incidence of AO in his or her practice. The article includes summaries of current preventive and treatment measures.
This article describes the surgical technique, indications and possible complications of the use of the buccal fat pad in the closure of oro-antral communications (OAC), following tooth extraction, in 56 cases. The technique was successful in all patients and did not interfere with the buccal sulcus depth. It is concluded that it can be safely applied in the closure of OAC.
A patient with congenital factor V deficiency combined with mental retardation and several congenital anomalies including cleft palate, dwarfism, microcephaly and right hydrocele testis is described. The levels of factor V activity and factor V antigen of plasma were significantly decreased. The platelet lysate obtained from him also showed a significantly low level of factor V activity. Palatoplasty and tooth extraction were successfully performed under transfusion therapy with fresh-frozen plasma.
Medullar aplasia is a hematological disease characterized by medullar dysfunction that results in a marked decrease of various hematological cellular elements. This produces anemia, infections of different etiologies and also, spontaneous or provoked hemorrhagic syndromes of varying importance. A case of medullar aplasia affecting a child, diagnosed after a tooth extraction is reported, and accompanied by its pathological characteristics. In addition, an easy reading E.L.I.S.A/ test for diagnosing herpes virus type 1 or 2 is presented.
The acquisition and maintenance of biological fixation of dental implants are achieved by a rapid and regenerative response of the recipient tissues, especially the vascular and osseous elements. This sequential response is described from initial osteogenesis through remodeling up to 20 weeks after implantation in Macaca fuscata monkeys. The sequential changes in the microvasculature and bone formation in three-dimensional bone-vasculature microcorrosion casts are studied by means of a plastic injection method devised by the author. Micrographs derived from microcorrosion casts reveal that all soft tissues (blood vessels walls, marrow, collagen fiber cells and the like) have been digested, leaving spaces once occupied by these elements, bone, and polymeric material that filled the blood vessels at death. The effects of biomaterial choice, general implant configuration, and interface configuration and material were sequentially analyzed. The effects of one- and two-stage healing variables were not analyzed. The Macaca fuscata monkeys were used for SEM examination of both bioinert and bioactive dental implant materials. The objective of this paper is to describe osseous healing at an implant interface, and compare it with osseous healing in tooth extraction sockets by use of a similar research approach in identical animal models.
Tuberculous lesions of the oral cavity are rare, primary lesions in particular. Three cases of different location are reported, two of them are secondary to pulmonary disease and the third one is a primary lesion after tooth extraction. Based on these cases and the literature reviewed we analyze the differences of these clinical situations, the diagnostic procedures needed and the excellent response they shows to treatment with tuberculostatic drugs.
This study evaluated new bone formation in human extraction sockets treated with demineralized freeze-dried bone allografts (DFDBA) and celloc occlusive membranes. Hard tissue biopsies of 7 sites in 6 patients were obtained 14 weeks to 13 months following extraction and grafting. Histologic analysis revealed that individual particles of DFDBA were discernible up to 13 months in situ. In all samples, all particles of DFDBA were well incorporated within new bone, which exhibited osteocyte-containing lacunae. Distinct cement lines clearly demarcated the DFDBA particles from the surrounding, intimately-apposed woven and lamellar bone. The marrow demonstrated a mild degree of fibrosis without signs of inflammatory reaction. There was also a notable lack of fibrous encapsulation of the allograft, and little osteoclasis was observed. Our findings demonstrate that commercially available DFDBA has the potential to function physically as a nidus for appositional new bone growth in alveolar sockets following tooth extraction. Further investigations of the biological activity of DFDBA in situ are warranted.
A case is reported of acute facial swelling following tooth extraction that failed to respond in a normal manner. The patient developed systemic signs and symptoms ultimately revealing the diagnosis of lupus erythematosus. The possibility of soft tissue lesions arising in some forms of lupus is emphasised by this report.
The results on the oral surgical management of patients with coagulation disorders at the Karolinska Hospital, Stockholm, during the period 1974-1985 have been compiled and compared with those obtained during the period 1965-1973. The present study included 380 tooth extractions performed in 250 treatment sessions in 107 patients. The incidence of postoperative bleeding and duration of hospitalization were reduced during the period of investigation.
AIM: This was to study prospectively a cohort of children as to whether behaviour at a 3-year examination, exposure to medical care and operative dental treatment are associated with each other, and with the level of dental apprehension at 9 years of age. METHODS: Data were collected at three subsequent dental examinations of 126 children (67 boys, 59 girls). Cooperation, general health condition and operative dental treatment during the preceding 3 years were obtained at dental examinations with 3-year intervals, i.e. at 3, 6 and 9 years of age. Children's dental apprehension was assessed at the age of 9 years. The data were analysed using an ordinal logistic regression model. RESULTS: Dental apprehension at 9 years of age was associated with frequent exposure to invasive medical care (p<0.001) and past experience of operative dental care (p<0.002), but not with cooperation at 3 years of age (p=0.124). CONCLUSION: Frequent invasive medical care in early childhood and operative dental treatment, tooth extractions in particular, are associated with dental apprehension at 9 years of age.
BACKGROUND: This systematic literature review determined the strength of evidence regarding whether patients with human immunodeficiency virus, or HIV, are at higher risk of developing complications from invasive oral procedures than similar patients without HIV. TYPES OF STUDIES REVIEWED: MEDLINE and EMBASE searches of the English literature from the early 1980s through April 2000 yielded five articles meeting the inclusion and exclusion criteria: original research, concurrent treatment of HIV-positive and HIV-negative subjects, presence of complications (for example, local or systemic infection, bleeding, alveolitis, delayed healing) resulting from extractions, orthognathic surgery, periodontal therapy, endodontic therapy, placement of dental implants, prophylaxis, or scaling and root planing. RESULTS: The authors found no studies involving orthognathic surgery, periodontal therapy, dental implants, prophylaxis, or scaling and root planing, and only one study reporting few immediate endodontic therapeutic complications. Thus, the evidence is insufficient with respect to any additional risk associated with these procedures among people with HIV/AIDS. Because of the few studies, low overall complication rates and variability in results from different analytic approaches, the authors consider the evidence to be too poor to rule in or out a meaningful relationship between HIV status and complications from tooth extractions. CLINICAL IMPLICATIONS: Limited published scientific evidence is available to guide clinicians in regard to possible increased risks of invasive oral procedures associated with the HIV status of the patient.
The Piezo "effect"describes a physical interaction, which is used in different fields of clinical medicine. An ultrasound technology results in the power of a surgical cut technique, which is able to distinguish between hard and soft tissue. With the presented instruments it is possible to treat bone mechanically in a piezo-surgical manner without hurting the surrounding soft tissues when touching them. Four examples: Tooth extraction before implantation under minimal grinding of bone, Gaining bone for peri-implant transplantation, Preparation of Sinus Lift, Exposing the inferior alveolar nerve demonstrate the use of Piezo-Surgery in the intraoral area. This method shows a remarkable addition to the intraoral operation techniques.
The post-operative pain therapy today places high demands on the quality of the drug applied as well as the necessary supplementary treatment. The results at hand show the pain time lapse and the effect of the applied methods when frequent interventions of oral surgery occur, for example wisdom tooth extraction. Characteristics of Ibuprofen-Lysinat have shown a quick pain relief within 20 minutes, after a dose of 1 to 2 tablets of 500 mg. The usage of a peripheral effective analgesic with high body compatibility has become the modern principle answer for post-operative treatment.
Third molar extraction is a common procedure frequently accompanied by moderate or severe pain, and involves sufficient numbers of patients to make studies relatively easy to perform. The aim of the present study was to determine the efficacy and safety of the therapeutic combination of 10 mg piroxicam, 1 mg dexamethasone, 35 mg orphenadrine citrate, and 2.5 mg cyanocobalamin (Rheumazin) when compared with 20 mg piroxicam alone (Feldene) in mandibular third molar surgery. Eighty patients scheduled for removal of the third molar were included in this randomized and double-blind study. They received (vo) Rheumazin or Feldene 30 min after tooth extraction and once daily for 4 consecutive days. Pain was determined by a visual analogue scale and by the need for escape analgesia (paracetamol). Facial swelling was evaluated with a measuring tape and adverse effects and patient satisfaction were recorded. There was no statistically significant difference in facial swelling between Rheumazin and Feldene (control group). Both drugs were equally effective in the control of pain, with Rheumazin displaying less adverse effects than Feldene. Therefore, Rheumazin appears to provide a better risk/benefit ratio in the mandibular molar surgery. Since the side effects resulting from nonsteroidal anti-inflammatory drug administration are a severe limitation to the routine use of these drugs in clinical practice, our results suggest that Rheumazin can be a good choice for third molar removal treatment.
Two patients with factor VII Padua abnormality were studied during prophylactic administration of factor VII concentrates for tooth extractions. The amounts administered were 15.8 and 17.2 units/kg body weight in 30 and 20 min, respectively. The end infusion factor VII activity levels were 55 and 64%, respectively. Survival times of the exogenous components were 6.5 and 6 h, respectively. Satisfactory hemolstasis was obtained in both instances.
The relationship between orthodontic treatment and symptoms and signs of temporomandibular disorders (TMD) was studied prospectively and longitudinally in 65 adolescent girls with Class II malocclusion. The subjects received orthodontic fixed appliance treatment with the straight-wire technique combined with or without extractions and were examined for symptoms and signs of TMD before, during, after, and finally one year post-treatment. Both symptoms and signs of TMD showed considerable fluctuations over the three-year period within the individuals. The general tendency was a decreased prevalence of symptoms of TMD over the three years. The prevalence of pain on mandibular movement and tenderness to palpation of the masticatory muscles was significantly less common during and after orthodontic treatment than before. Clinically registered TMJ clicking increased slightly over the three year period. One orthodontic treatment effect when normalizing Class II malocclusions with fixed appliances was a decreased prevalence of functional occlusal interferences. We concluded that the orthodontic treatment either with or without tooth extractions did not increase the risk for TMD or worsen pre-treatment signs of TMD. Subjects with Class II malocclusion and pre-treatment signs of TMD of muscular origin seemed rather to benefit functionally from orthodontic treatment in a three-year perspective.
This paper reports histologic and histomorphometric results concerning bone healing around 13 pure titanium screw-shaped root-form implants that were placed in three mongrel dogs immediately after extraction of maxillary and mandibular premolars. Osseous healing around the implants showed a great deal of variability depending on the arch in which the implant was placed and on the original anatomy of the implant site. Implants placed in the mandible showed the greatest amount of bone apposition, with a mean total bone of 60.3%. Implants placed in the maxilla showed less bone and greater variability both visually and statistically, with a mean total bone of 46.3%. The values obtained for bone after 5 months of healing of the control sites were consistent with the values obtained for bone approximating the implants after the same time period. This was true for both arches. It was impossible to visually or statistically discriminate between sham surgical control sites and routine control sites or between implant sites and either of the control sites. Implant surgical procedures and implant placement seemed to have little effect on the tabulated values beyond tooth extraction alone. This research suggests that immediate implants have the potential for developing good bone apposition depending on the area of implantation.
BACKGROUND: Pain is defined as both a sensory and an emotional experience. Acute postoperative tooth extraction pain is assessed and treated as a physiological (sensory) pain while chronic pain is a biopsychosocial problem. The purpose of this study was to assess whether psychological and social changes occur in the acute pain state. METHODS: A biopsychosocial pain questionnaire was completed by 438 subjects (165 males, 273 females) with acute postoperative pain at 24 hours following the surgical extraction of teeth and compared with 273 subjects (78 males, 195 females) with chronic orofacial pain. Statistical methods used a k-means cluster analysis. RESULTS: Three clusters were identified in the acute pain group: 'unaffected', 'disabled' and 'depressed, anxious and disabled'. Psychosocial effects showed 24.8 per cent feeling 'distress/suffering' and 15.1 per cent 'sad and depressed'. Females reported higher pain intensity and more distress, depression and inadequate medication for pain relief (p < 0.001). Distress and depression were associated with higher pain intensity. The developed questionnaire had tested reliability (test-retest r = 0.89) and estimated validity. CONCLUSION: Cluster analysis showed constituent groups with a range of psychosocial effects in acute postoperative dental extraction pain and is associated with an increase in pain intensity.
