Long-term effects of orthodontic forces on the morphology of the rat-incisor socket and its location in the mandible.

The effect of orthodontic force application on the rat-incisor socket and mandible was studied on roentgenograms. A mean linguo-intrusive force of 19 +/- 0.6 g was applied continuously to the shortened left lower incisor for a period of two (group A) and four weeks (group B). A third group of rats, subjected to shortening of the left mandibular incisor only, served as a hypofunctional control (group C). A fourth group of normal rats constituted the intact control (group D). After a recovery period of three months, the animals were killed, and standardized roentgenograms of the cleaned mandibles were taken. Socket and mandibular dimensions were measured on magnified tracings of the roentgenograms. Comparison of groups A and B with the control groups, on the one hand, and of group C with group D, on the other, facilitated isolation of the hypofunctional factor. In groups A and B, the orthodontic forces caused changes in the parameters affected (i.e., socket area, alveolar bone thickness, mandibular dimensions) and not affected by hypofunction (i.e., socket angulation and location, anterior-socket length). The former findings implies modification of the adaptive capability of dental structures to functional demands. It is concluded that mechanical loading of the incisor for two to four weeks causes long-lasting changes in the socket and its surrounding bone.

Influence of smoking upon the postoperative course of lower third molar surgery.

OBJECTIVES: To determine whether smoking influences the postoperative course (pain and trismus) of lower third molar surgery, with a clinical evaluation of surgical wound condition and analysis of the possible differences between smokers and nonsmokers. DESIGN: The study subjects were randomly distributed into two groups (smokers and nonsmokers) and subjected to lower third molar extraction in the Unit of Oral and Maxillofacial Surgery (Madrid Complutense University, Spain). The study variables were trismus after 7 days, the intensity of pain and the need for rescue medication during a period of one week. The surgical wound was also assessed (color, presence of plaque, etc). RESULTS: Two cases of postoperative infection were documented among the smokers, and postoperative trismus was found to be greater among the latter (p=0.05). CONCLUSIONS: There were no statistically significant differences between the two groups in terms of pain, though trismus was greater among the smokers. Smoking did not influence wound condition (color, marginal inflammation, appositioning of the margins, ulceration, etc).

Oral surgery.

An overview of the various possibilities for oral surgery urgent care to the oral region has been presented. Modern treatment procedures have been described. The recent advances in dental science have become superior to what they were just a few short years ago; however, we must never forget the variabilities of human responses to any of our treatment techniques, and we must not be dogmatic in our approach. We should all be able to diagnose, interpret, and alter any of our treatment techniques as necessary.

Complications after mandibular third molar extraction.

The records of 1,797 patients were retrospectively examined to analyze the possible relationships between postoperative complications following mandibular third molar extraction and parameters such as age, sex, indication for surgery, position of the molar, surgical experience, surgical technique, and postoperative care. Older patients tended to suffer more often from complications. Surgery performed while there were signs of pericoronal inflammation also resulted in more complications. There was no statistically significant difference in the mean complication rate arising from surgery performed by staff members and the rate when surgery was performed by residents. There seems to be no reason for patients to return routinely for removal of resorbable sutures or other postoperative care because this practice does not result in a decrease in postoperative symptoms.

Bioabsorbable root analogue for closure of oroantral communications after tooth extraction: a prospective case-cohort study.

OBJECTIVE: To assess the clinical capacity of a bioabsorbable root analog to close oroantral perforations after extraction. STUDY DESIGN: In this prospective case-cohort study, 20 consecutive patients with oroantral communications greater than 2 mm were treated with a bioabsorbable root analog (RootReplica). Patients were followed up clinically and radiographically for 3 months to monitor the healing process. RESULTS: Root replicas could be placed in 14 patients, whereas 6 patients required the socket to be covered with a buccal sliding flap. In the latter cases, fragmentary roots or overly large defects prohibited replica fabrication or accurate fitting of the analog, respectively. Healing was uneventful in all patients, and epistaxis, swelling, or pain was observed only in patients treated with flaps. CONCLUSIONS: The method described is a valuable alternative method with which to close oroantral communications but cannot be performed in all patients because of technical limitations.

Wound healing following dental extractions in rabbits: effects of tranexamic acid, warfarin anti-coagulation, and socket packing.

We have investigated the importance of the coagulation and fibrinolytic systems for wound healing following dental extractions. Four front teeth were extracted in rabbits; wound healing was measured as time until complete epithelial closure. The antifibrinolytic agent tranexamic acid shortened duration of wound healing in normal rabbits. Anti-coagulation with warfarin delayed epithelial closure, which was, however, normalized by simultaneous administration of tranexamic acid, whereas complete packing of the socket with oxidized cellulose had no corrective effect. Apical packing together with tranexamic acid gave normal healing. It is concluded that the quality of the fibrin network within the dental socket determines the rate of wound healing; oxidized cellulose is not an adequate substitute for fibrin.

The human mandibular canal arises from three separate canals innervating different tooth groups.

The purpose of this study was to describe the prenatal formation of the human mandibular canal. Since bony canals develop in prenatal life around the nerve paths, it was assumed that the canal pattern could reflect the pattern of innervation of the dentition. Mapping of this early canal pattern does not appear to have been undertaken before. The material consisted of anthropological mandibles from the National Institute of Anthropology and History, Mexico City. A total of 302 human hemimandibles from the latter half of the prenatal period was investigated. The length, measured from the mental symphysis to the mandibular condyle, ranged from 28 to 60 mm. The dento-alveolar maturity was classified in two stages according to the appearance of alveolar sockets of deciduous and first permanent molars. The mandibles were radiographed with guttapercha points inserted into the canal openings (foramina) on the lingual surfaces of the mandibular rami. The study showed that the canal to the incisors appeared first, followed by the canal to the primary molars, and last by the one or more canals to the first permanent molars. In the most mature group, three different canals always occurred in each hemimandible. The canals were directed from the lingual surface of the mandibular ramus toward the different tooth groups. The inferior alveolar nerve presumably occurs in the mandible as three individual nerve paths originating at different stages of development. It is suggested that rapid prenatal growth and remodeling in the ramus region result in a gradual coalescence of the canal entrances that is obvious at birth. It is hypothesized that the pattern of tooth agenesis within the three groups of teeth is related to the three separate paths of innervation of the dentition.

Complications following removal of impacted third molars: the role of the experience of the surgeon.

The incidence of complications associated with the removal of impacted third molars in a group of 500 patients treated by oral surgery faculty were compared with the incidence of complications in 208 patients treated during the same period by residents of oral and maxillofacial surgery. The results show that complications were more numerous after the removal of third molars classified as partial bony or complete bony impactions, and that less-experienced surgeons had a significantly higher incidence of such complications.

The effect of polylactic acid granules on the incidence of alveolar osteitis after mandibular third molar surgery. A prospective randomized study.

OBJECTIVE: To evaluate the effect of polylactic acid granules placed in third molar sockets on the incidence of alveolar osteitis. STUDY DESIGN: A prospective randomized study with 161 patients (322 bilaterally impacted mandibular third molars). RESULTS: The sockets in which the polylactic acid granules were placed had a significantly higher rate of alveolar osteitis (23.6%) than did the control sockets (13.58%). In all subgroups analyzed, the incidence of alveolar osteitis was higher in the experimental (polylactic acid) group. CONCLUSION: On the basis of the findings of this study, polylactic acid granules do not reduce the incidence of alveolar osteitis and may actually contribute to a higher incidence of alveolar osteitis.

Clinical comparison of hydroxyapatite-coated titanium dental implants placed in fresh extraction sockets and healed sites.

The placement of hydroxyapatite-coated dental implants in fresh extraction sockets was compared to placement in adjacent healed sites in 14 patients. Systematic sequential documentation was obtained regarding periodontal health, radiographic bone levels, and implant stability at the time of implant placement, at uncovering, and from 8 to 24 months (mean 16 months) after loading and restoration delivery. There were no significant differences in any clinical parameter between those implants placed in fresh extraction sockets and those placed in healed areas. Periodontal health, maintenance of crestal bone levels, and implant stability were excellent for implants placed in both types of recipient sites. The results of this study suggest that hydroxyapatite-coated dental implants can be successfully placed in fresh extraction sockets utilizing otherwise standard implant placement techniques, and that they appear to clinically perform equally well in fresh sockets and healed sites.

Side effects and complications associated with third molar surgery.

A retrospective analysis of complications and side effects associated with surgery for 1000 mandibular and 500 maxillary impacted third molars was performed. The analysis included 614 patients with impacted mandibular third molars and 274 with impacted maxillary third molars who were treated in a 5-year timeframe from 1987 to 1992. The incidence of intraoperative complications and side effects of mandibular third molar surgery was 1.1% and 4% for maxillary third molar surgery whereas postoperative complications were 4.3% and 1.2%, respectively.

A comparison of morbidity following the removal of lower third molars by the lingual split and surgical bur methods.

Fifty-two consecutive healthy patients with bilateral, similarly impacted mandibular third molars were studied. For each patient, both third molars were removed at the same operation by the same experienced operator. On one side, the lingual split method by chisel was used; on the other, the buccal approach with surgical bur. Standard preoperative and postoperative drug regimens were used. Pain, facial swelling (visual analogue scales), and lingual and labial sensory disturbance were recorded for each side by the patients at home 6, 24, and 48 h and 7 days after surgery. Wound healing was assessed at 4 weeks. There were no statistically significant differences between methods in relation to pain, facial swelling, sensory loss, infection, or periodontal pocket depth distal to the second molar, although 2% of third molars removed by chisel had lingual sensory disturbance at 7 days, as compared with 8% where burs had been used. There were no statistically significant differences between duration of procedures; mean operating time with burs was 8.28 min (range 4-15 min) and with chisels 7.57 min (range 4-15 min). This study provided no evidence of difference in either efficiency or outcome between two standard methods of removing lower third molars.

A monitoring and evaluation study of third molar surgery complications at a major medical center.

This monitoring and evaluation study of third molar surgery complications took place over a 6-month period of time. The goal of the study was to determine complication rates following third molar extraction. A comparison was made between the staff's and residents' post-operative complication rates and patients receiving tetracycline powder in the extraction sockets vs. no antibiotics. Complication rates were compared in males vs. females, and in four different age groups. The study helped improve patient care by showing that alveolar osteitis rates decreased when all patients received topical tetracycline. It also confirmed that the experience of the surgeon, patient age, and gender influence complication rates.

The effects on extraction wound healing of a new drug combination introduced for use in the prevention of post-extraction complications. A preliminary report.

Fifteen extraction sockets packed with a new drug combination which includes a local anaesthetic (cincain chloride), a local antiseptic (tri-iodomethane) and two drugs with a potent antifibrinolytic activity (tranexamic acid and propyl-hydroxy-benzoic acid) in an absorbable gelatin sponge (Gelfoam) as a vehicle, were histologically assessed with special reference to the parameters related to wound healing. As a control, the same number of sockets were allowed to heal spontaneously and similarly assessed. Healing of the extraction wounds seemed to follow the normal sequence in both series, and no histological signs suggestive of a delay in the healing process could be found in any of the sockets studied. Also the mast cell count previously considered to be of importance in the connective tissue repair was found to be unaffected by the test substance. These results, together with the previously presented data on the clinical efficacy of the drug combination studied, suggest that a larger clinical study should be carried out to assess its value as a preventive measure against the development of the post-extraction symptoms, including dry socket.
