[Analysing the effects of tooth extraction under acupuncture anesthesia in 825 cases of senior].

It has been found that the effects of tooth extraction under acupuncture anesthesia (AA) for the old patients are generally quite good. In order to verify this result, the authors had statistically analysed 825 cases aged over 60 years (Group A) and equal quantity whose age were between 18-40 years old (Group B) out of more than 4000 cases whose records of AA were rather completely during 1973 to 1988. 1. There was no significant difference under AA for different sexes. 2. The differences of the excellent rate of AA between Group A and Group B were extremely evident either in the positions of the tooth or the reason of tooth extraction. The former was 89.04% and the latter 76.20% (P less than 0.005). 3. Although a low rate in excellence of tooth extraction under simple AA (only 75.58%), not so good as the effect by AAA (an average about 88.21%), the simple AA was more common and more easier to be accepted by patients. 4. Tooth extraction under AA has been proved to be safe, effective and without any complications. 5. The reasons for the senior to extract their teeth were almost for the broken crowns and of roots or the purposes of prosthetic restoration. Even though the pain thresholds in the senior were commonly higher. It is still an important factor of the good effect and good rate of tooth extraction under AA. Referring to the statistics in this study the authors suggest that the hospitals which can use the AA for tooth extraction adopt the method as the first choice of anesthesia method to the senior who intends to accept it.

Tooth extraction in HIV sero-positive patients.

Tooth extraction is the dental treatment most commonly carried out among HIV positive patients. In this paper we propose a simple protocol for dental extractions in patients of this type, based on a review of the literature and on our own experience in this field. The factors to be considered when planning a dental extraction for HIV positive patients are: diagnosis of the lesion justifying the need for tooth extraction and medical assessment of the patient including the infection pathway, the stage of the disease, laboratory tests and drug therapy. The most frequent post extraction complications are a delay in the wound healing process, alveolitis and surgical wound infection. Fortunately, these complications tend to be rather uncommon and not too severe; they can be managed on an out-patient basis and their prevalence will probably tend to decrease with the introduction of the new anti-retroviral drugs for HIV-1.

Titanium membranes in prevention of alveolar collapse after tooth extraction.

BACKGROUND AND PURPOSE: The resorption of alveolar bone following tooth extraction results in a narrowing and shortening of the residual ridge, which leads to esthetic and restorative problems, and reduces the bone volume available for implant therapy. The aim of this study was to evaluate the prevention of alveolar collapse after tooth extraction, using titanium membrane (Frios Boneshield; DENTSPLY Friadent, Mannheim, Germany), associated (or not) with autologous bone graft. MATERIALS AND METHODS: A total of 10 nonsmoking healthy subjects, ranging from 35 to 60 years old, were selected for this study. Each patient had a minimum of 2 uni-radicular periodontally hopeless teeth, which were scheduled for extraction. After the procedure, 2 titanium pins were fixed on the vestibular bone surfaces that were used as references for the initial measures (depth, width, and height) of the socket. Of the sockets,1 was randomly chosen to be filled with autologous bone graft (test) removed from superior maxillary tuber, and the other one did not receive the graft (control). A titanium membrane was adapted and fixed, covering the sockets, which remained for at least 10 weeks. After a 6-month healing, the final measures were performed. RESULTS: There was exposure of the membrane in 5 of the 10 treated subjects. Average bone filling (+/-standard deviation) among the 10 subjects was 8.80 +/- 2.93 mm (range 4-13) in the control group and 8.40 +/- 3.35 mm (range 4-13) in the test group. Average bone loss in width in both group was 1.40 +/- 1.97 mm (range -4-1) in the control group and 1.40 +/- 0.98 mm (range -4-0) in the test group. There was no significant statistical difference between groups considering the evaluated standards. CONCLUSION: The use of titanium membrane, alone or in association with autogenous bone, favored the prevention of alveolar ridge after tooth extraction. This membrane seems to be a possible and safe alternative to other nonresorbable membranes when the prevention of alveolar ridge resorption is the objective.

[Survey of reasons for tooth extraction in the framework of government-sponsored dentistry].

The purpose of this study was to determine the reasons for tooth extraction and to estimate the state of dental health in Hungary. Questionnaires with detailed instructions were sent to 300 Hungarian dental practitioners selected at random asking them to record and submit data on every extracted tooth during one month in 1986. They were also asked to give the reason for extraction in each case. 115 dentists returned completed forms on 7978 teeth which they had extracted. The dental caries was the most frequent cause for extraction (64%), followed by periodontal diseases (25.1%). 3103 teeth, 60.73% of teeth extracted because of caries had not been treated before the extraction. The results show that the dental caries remains the most important challenge for the Hungarian dental service during the next decades. The great numbers of extractions per dentist reveal the inadequacy of dental service in Hungary.

Healing following tooth extraction in cyclosporine-fed rats.

Healing after tooth extraction was studied in rats treated with cyclosporine-A (CSA) for four weeks. Sixty male Sprague-Dawley rats were assigned to one of three groups of 20 rats each. The maxillary right molars were extracted from two groups; the third group served as a non-extraction control. The non-extraction group and one extraction group (vehicle control) received the solvent mineral oil daily, and the other extraction group received 15 mg/kg CSA in mineral oil. Five rats from each group were killed 5, 10, 14 and 28 days after extraction and samples analyzed histologically. On days 5 and 10, bone volume was significantly lower and marrow volume significantly higher in both extraction groups than in the non-extraction group. The fractional-formation surfaces were significantly lower in the extraction groups than in the non-extraction group on day 5 only. Osteoid volume was significantly higher in the extraction vehicle control group than in the other two groups on days 10 and 14; however, the osteoid volume was higher in the CSA group than in the other two groups on day 28. On days 14 and 28, bone volume was lower and marrow volume higher in the CSA group than in the extraction vehicle control and non-extraction groups. On day 28, bony surface areas were significantly greater in the CSA group than in the extraction vehicle control and non-extraction groups. Soft-tissue evaluation showed significantly greater epithelial areas, connective tissue areas and total tissue areas in the CSA group than in the extraction vehicle control group on day 28, but not on day 14. These data suggest that CSA may influence healing of both the gingival tissue and the alveolar bony sockets in the tooth-extraction wound. Further detailed study is needed to identify the mechanisms responsible.

Reasons for tooth extraction in a Brazilian population.

AIM: To identify the reasons for tooth extraction in Recife, Brazil and to test whether they differ by socio-economic groups and levels of caries experience. DESIGN: Cross-sectional survey. SETTING: Ten health centres of the public health system and ten health centres of insurance companies. PARTICIPANTS: Patients attending health centres. METHODS: Ten dentists from each selected centre and two patients from each selected dentist were randomly selected from; the list of all health centres in Recife, all dentists carrying out dental extractions at each selected centre and all patients who had an appointment with the selected dentists respectively. Participants were examined by both the researcher (AC) and dentists. OUTCOME MEASURE: Reasons for tooth extraction. RESULTS: Of the 404 teeth extracted, 70.3 per cent were because of caries and its sequelae; 15.1 per cent because of periodontal disease; 6.4 per cent for pre-prosthetic reasons; 3.7 per cent wisdom teeth, 2.5 per cent for orthodontic reasons and 1 per cent for trauma and patient's request. A trend was observed for patients with less than secondary school education and lower salaries to have more tooth extraction due to caries, but the differences were not of statistical significance.

Effectiveness of an educational program in reducing the incidence of wrong-site tooth extraction.

OBJECTIVES: The aim of the study was to investigate the effectiveness of an educational program on the reduction of the incidence of wrong-site tooth extraction at the outpatient department of a university hospital in Taiwan. STUDY DESIGN: Data collected from cases of wrong-site tooth extraction during 1996 to 1998 were used to develop a specific educational intervention that was implemented from 1999 to 2001. The annual incidence of erroneous extraction was compared between the preintervention and intervention periods. The factors contributing to wrong tooth extraction were also analyzed. RESULTS: The annual incidence rates of erroneous extraction from 1996 to 1998 were 0.026%, 0.025%, and 0.046%, respectively. During the intervention period from 1999 to 2001, wrong-site tooth extraction did not occur at the department. There was a significant difference in the incidence of erroneous extraction between the preintervention and intervention periods (P<.01). Cognitive failure was the most frequent form of active failure responsible for wrong-site tooth extraction, whereas communication and training were found to be major latent factors contributing to these errors. CONCLUSIONS: Our results suggest the effectiveness of an educational program comprising case-based materials, information feedback, and clinical guidelines in reducing the incidence of wrong-site tooth extraction.

Reasons for tooth extraction among patients in Sebha, Libyan Arab Jamahiriya: a pilot study.

We investigated the causes of tooth extraction among patients in Sebha in southern Libyan Arab Jamahiriya. A total of 600 patients who had undergone tooth extraction were surveyed. We found more males (68%) than females had had teeth extracted and also patients with no education (53%). Caries and periodontal disease were the main causes of tooth extraction. For those patients who opted for tooth extraction over other treatment, they mostly did so for financial reasons. There was generally poor oral hygiene and oral knowledge, which should be tackled.

Evaluation of success rates of immediate and delayed implants after tooth extraction.

OBJECTIVE: To evaluate the success rates of immediate and delayed placement of implants with respect to the causes of tooth extraction and implant positions. METHODS: A total of 310 dental implants (immediate implants:delayed implants = 76:234) were inserted into 80 patients. The types, sizes and positions of the implants and the causes of tooth extraction were recorded. We then investigated the relationship of implant loss with the causes of tooth extraction and placement methods. RESULTS: A higher failure rate was found for the implants in the posterior region of the maxilla, and when periodontitis was cited as a reason for tooth extraction. The overall success rates were 93.4% and 95.7% in the immediate and delayed implant placement groups, respectively, after a 2-year follow-up. No obvious relationship of success rate was observed with the implant placement method, cause of tooth extraction, and implants' position. CONCLUSION: The immediate placement of implants into fresh extraction sockets could offer advantages over the delayed implant placement. It seems to be a safe and predictable method for patients.

[Size of wound area and frequency of alveolitis after tooth extraction].

Electron spin resonance was used to measure out 160 tooth root surfaces. These data represent a measure for wound area sizes after tooth extractions. A comparison of these values with clinical data results in a correlation between the size of wound area and the frequency of inflammatory healing disorders after tooth extractions.

Various reasons for permanent tooth extractions in a Caribbean population--Antigua.

A study was undertaken in September 1990 to investigate the reasons for permanent tooth extractions in Antigua. Eight out of 10 dentists on the island were requested to record permanent tooth extractions, including tooth type and reasons for extraction, during a 6 week study period. All 8 dentists provided data which indicated that 471 teeth were Extractions for orthodontic and impaction reasons comprised 4.3 per cent of tooth extrac-irregularly attending dental services. The principle reason for extractions was caries (61.6 per cent). Periodontitis (29.9 per cent) was the next most frequent reason for extractions and it became the predominant indication for tooth loss after 40 years of age. Extractions for orthodontic and impaction reasons comprised 4.3 per cent of tooth extraction, but these causes disappeared after 30 years of age. Restorable teeth were not commonly removed. The tooth types most frequently extracted due to caries were lower first molars and upper molars. Most commonly extracted, periodontally involved teeth were lower central incisors and upper third molars.

[Prevention of alveolar ridge resorption after tooth extraction--a review].

Alveolar bone resorption is frequently observed after tooth extraction. Atrophy of the alveolar ridge may cause esthetic and surgical problems in prosthetic dentistry. Augmentative measures may thus be required to guarantee optimal prosthetic replacement of the lost tissues. Augmentative bone treatment may result in extensive surgical interventions and increased treatment costs. Alveolar ridge prophylaxis immediately upon tooth extraction may reduce such sequelae for both, the treating dentist and the patient. Attempts to reduce alveolar bone resorption have included the placement of natural roots, root analogues, and immediate implants into the extraction socket, sometimes in combination with membrane or graft techniques. In the current review of the literature, techniques for alveolar ridge preservation are discussed.

Periodontal status and total tooth extraction in a medium-sized city in the Netherlands.

A combined sociodental research project was started in the city of Groningen in 1982 aimed at gaining insight into the reasons for total tooth extraction. Patients showing up for total tooth extraction during 1982 participated in this study by filling out a questionnaire concerning the underlying reasons for their decision to have all their teeth extracted. The dentists in this city were asked to collect all the extracted teeth and to fill out a short questionnaire for each patient about the reason (diagnosis) for the total tooth extraction. The periodontal status of the extracted teeth was established afterwards by measuring the percentage of the loss of attachment (L.A.). It appeared that most surfaces in the molar region and the front teeth in the mandible were affected by periodontal disease. Advanced generalized periodontal disease was established in 17% of the patients, accounting for 64% of all teeth with an L.A. measurement of greater than 50%. Periodontal disease could not be identified as the main clinical condition requiring tooth extraction: even in the group of 55 yr of age and older advanced periodontal disease was found in only one third of the extracted teeth. Finally, the contribution of regular dental attendance to periodontal health is discussed.

Measurement of tooth extraction forces in upper incisors.

A new method, applied for the first time in this research, was used for measurement of tooth extraction forces. The research has been done in a group of 50 examinees to whom the tooth extraction has been done with lower premolar forceps - forceps "13" and in the control group of 54 examinees in whom the tooth extraction has been done with upper incisive forceps - forceps "1". The measurement instrument registered the extraction forces values in both types of forceps. There was no difference in any parameters in these two groups except in used pressure. While using the forceps "13", a significantly lower tooth extraction force was measured than the force measured while using the forceps "1" (p < 0.001). This means that in clinical work we can already apply noticeably less force using the lower premolar forceps for the extraction of the upper incisors (in the moments of rotation up to 70%). These results are meaningful, because they lead to better and improved instrument solutions and working techniques.

Analgesic effects of acupuncture on pain after mandibular wisdom tooth extraction.

We evaluated the analgesic effects of acupuncture on postoperative pain by comparing patients who underwent routine tooth extraction alone (control group) and those who underwent tooth extraction in combination with acupuncture (experimental group) by the random allocation method. As teeth easy to extract. requiring no gingival incision (grade A) or those difficult to extract, requiring gingival incision or bone cutting (grade B). As local anesthesia, 1.8 ml or 3.6 ml of 2% xylocaine was used. The LI.4, Hegu on both sides and ST.7, Xiaguan and ST.6, Jiache on the affected side were selected. Low frequency electrical acupuncture was performed. When acupuncture was used in combination with tooth extraction, 3 of 22 patients did not develop postoperative pain. In patients with wisdom teeth difficult to extract (grade B), acupuncture used in combination with local anesthesia decreased postoperative pain.

Bone healing and soft tissue contour changes following single-tooth extraction: a clinical and radiographic 12-month prospective study.

Preservation of alveolar bone volume following tooth extraction facilitates subsequent placement of dental implants and leads to an improved esthetic and functional prosthodontic result. The aim of the present study was to assess bone formation in the alveolus and the contour changes of the alveolar process following tooth extraction. The tissue changes after removal of a premolar or molar in 46 patients were evaluated in a 12-month period by means of measurements on study casts, linear radiographic analyses, and subtraction radiography. The results demonstrated that major changes of an extraction site occurred during 1 year after tooth extraction.

[Tooth extraction in cases of dental abscess].

BACKGROUND: Surgical relief and drainage as well as adjunct medicinal and physical therapy of dental abscesses are indisputable treatment options. It is currently controversial at what time the tooth extraction should take place. The aim of this study was to determine whether there are differences in treatment success depending on the time of tooth extraction. PATIENTS AND METHODS: A randomized patient sample (n=177) from two clinics was examined that differed in the therapy only regarding the time of tooth extraction. Post-surgical complications, inpatient care, duration of surgeries and incidents during anesthesia were examined. RESULTS: Statistically significant differences for inpatient care were impressive. done Abscess incision and tooth extraction performed simultaneously led to an average hospital stay of 8 days compared to 11 days when done at two different times. Duration of surgeries was also significantly shorter for the single procedure. Post-surgical complications only occurred in 2-4% of all cases. DISCUSSION: Opinions expressed in the literature include complete refusal to do tooth extraction immediately, or extraction of the causal teeth while providing antibiotic protection or even complete support of immediate extraction. Considering all factors, this study supports a single procedure with a shorter duration of hospital stays depending on local, personnel and logistical circumstances, especially regarding the forthcoming introduction of the DRGs.
