Tooth loss in a sub-urban Nigerian population: causes and pattern of mortality revisited.

AIM: To determine the current causes and pattern of tooth loss in Ile-Ife Nigeria. DESIGN: A retrospective review of records of dental extraction patients. SETTING: The dental hospitals of the Obafemi Awolowo University Teaching Hospital situated in South Western Nigeria. PARTICIPANTS: All patients that had dental extractions between January 1996 and December 2002. METHOD: Patients' case records were analysed for demographics, reason(s) for dental extraction, tooth/teeth extracted, method of extraction and complication(s). MAIN OUTCOME MEASURE: Reasons for tooth extraction and the pattern of tooth loss. RESULTS: 6348 (12.3%) of hospital attendees aged 4-102 years (mean 35 +/- 16.8 years) had extraction of 8338 teeth. A statistically significant female preponderance was observed. Dental caries was the leading cause of tooth loss (56.4%) followed by periodontal disease (24.6%). This shows a reversal of a trend reported in a previous study in the same location. Over half (69.2%) of the extracted teeth were molars (mostly mandibular). Only 4.1% extractions were trans alveolar. 3.9% were complicated by dry socket. CONCLUSION: 12.3% of the hospital attendees had undergone dental extraction. Despite previous warnings of a steady rise in dental caries, it has become the leading cause of tooth loss in our hospital. The urgent need to institute standardised preventive measures was highlighted.

The prophylactic use of propylic ester of p-hydrobenzoic acid on alveolitis sicca dolorosa. A preliminary report.

A double-blind experiment was performed to test the possible prophylactic effect of the antifibrinolytically active propylic ester of p-hydroxybenzoic acid (PEPH) on alveolitis sicca dolorosa (dry socket). Tablets containing PEPH or placebo were inserted at random selection into the alveoli of forty-five consecutive patients, each of whom had had an impacted mandibular third molar removed. The prophylactic effect of PEPH in this study was found to be highly significant as compared to that of placebo, and no patients in the experimental group developed alveolitis sicca dolorosa.

Dry socket incidence compared after a 12 year interval.

A survey was conducted over a 3 month period in 1983 to examine the influence of clinical factors on the incidence of dry socket (DS) after extractions of permanent teeth under local analgesia. The findings were compared with those of a similar 3 month survey in the same hospital in 1971. Age, sex and extraction site each significantly influenced the incidence of DS. The major difference from the 1971 survey was an increase in the DS incidence from 3.0% to 4.0% of extractions. This occurred mainly following multiple extractions and may indicate that patients, particularly in this group, are nowadays less tolerant of any post-extraction discomfort and hence more readily return for attention. This is particularly relevant in the present study since the broad definition of DS used in both surveys embraced even the mildest presentations of disturbed socket healing.

The effect of chlorhexidine irrigation on the incidence of dry socket: a pilot study.

A pilot study was conducted to measure the reported incidence of dry socket following pre-operative irrigation and mouthrinsing with either 0.2% (w/v) chlorhexidine gluconate or normal saline or with no irrigation (control). Three hundred and twenty-four patients presenting for the single extraction of a lower premolar or molar under local anaesthesia were divided into three equal groups; no irrigation, irrigation with saline and irrigation with a 0.2% (w/v) chlorhexidine gluconate solution. After administration of the local anaesthetic agent, 10 ml of the test solutions were applied to the gingival crevice using a blunted needle. The solutions were retained in the patients mouth for 2 min following irrigation. Pre-operative irrigation of the gingival crevice and mouthrinsing with 0.2% (w/v) chlorhexidine gluconate significantly reduced the number of dry sockets. There was no significant reduction in the number of dry socket cases following irrigation and rinsing with normal saline. The irrigation technique, using 0.2% (w/v) chlorhexidine gluconate is safe, inexpensive, easy to apply and can be recommended for routine use in dental practice, to reduce the incidence of dry socket.

The effect of smoking on immediate post-extraction socket filling with blood and on the incidence of painful socket.

The effect of habitual smoking on post-extraction socket filling with blood and on the incidence of painful socket, was investigated. Data were collected from 2417 adult dental out-patients in whom 3541 extractions were performed under local anaesthesia. Post-operative socket filling with blood was significantly reduced in smokers, compared with non-smokers (p less than 0.01). There was a higher incidence of painful socket in heavy smokers (20 or more cigarettes per day), compared with nonsmokers (p less than 0.05). There was a significant relationship between immediate post-extraction socket blood level and the incidence of painful socket; sockets which showed poorer filling were more likely to develop painful socket (p less than 0.02). Smoking appeared to have an adverse effect upon the healing of extraction wounds.

Effects of a chlorhexidine gluconate oral rinse on the incidence of alveolar osteitis in mandibular third molar surgery.

Alveolar osteitis (dry socket) continues to be a frequent sequela of third molar surgery. Chlorhexidine 0.12% used as an oral rinse has been reported to reduce the incidence of dry socket. This study compares the effectiveness of 0.12% chlorhexidine used as a preoperative rinse and immediate postextraction irrigant with 1) similarly used 0.05% cetylpyridium, preoperative chlorhexidine rinse and postextraction saline irrigation, and 2) only postextraction irrigation with normal saline in the reduction of alveolar osteitis in mandibular third molar extractions. The results indicate that chlorhexidine and cetylpyridium were no more effective in the reduction of alveolar osteitis than postextraction irrigation with normal saline.

The effect of a chlorhexidine rinse on the incidence of alveolar osteitis following the surgical removal of impacted mandibular third molars.

A prospective randomized double-blind placebo-controlled study was conducted with 139 patients (278 bilaterally impacted mandibular third molars) to determine the effect of a perioperative 0.12% chlorhexidine gluconate rinse on the incidence of alveolar osteitis following surgical removal of impacted mandibular third molars. A statistically significant 60% reduction in the incidence of alveolar osteitis was obtained in the chlorhexidine group compared with the placebo group. In most subgroups analyzed, chlorhexidine was associated with at least a 50% reduction in alveolar osteitis compared with control groups.

A new combination of drugs intended to be used as a preventive measure for the postextraction complications. A preliminary report.

Fifteen extraction sockets packed with a new drug combination, including a local anesthetic (cincain chloride), a local antiseptic (tri-iodomethane) and two drugs with a potent antifibrinolytic activity (tranexamic acid and propyl-hydroxybenzoic acid) in Gelfoam as a vehicle, were assessed clinically with special reference to the development of the postextraction symptoms, dry socket included. As a control series, 15 extraction sockets allowed to undergo a spontaneous healing were similarly evaluated. All the sockets in both series were found to heal according to the normal sequence. There were, however, statistically highly significant differences between the two series with regard to the clotting time, postextraction pain and the need for adjunct analgesics, in favor of the sockets packed with the compound in test. The observed beneficial effects of the test compound are discussed in the light of the recently elucidated etiologic and pathogenetic mechanisms leading to the development of dry socket, and a conclusion is drawn that the present results, although preliminary due to the limited number of patients, advocate further evaluation of the new drug combination and its applicability in the prevention of the troublesome postextraction complications, including dry socket.

[The incidence and dynamics of the development of alveolitis over the course of a year].

Analysis of the results of 8019 operations for removal of teeth, carried out within 5 years by one physician under the same conditions, has shown that alveolitis developed in 1.87 +/- 0.15% of cases, on an average. The risk of alveolitis was found the highest from December to March and the lowest from June to September, as evidenced by estimation of the index of the seasonal fluctuations in the morbidity (a total of 120 to 140 teeth were removed within a month, on an average).
