The incorporation of alanine C14 in protein synthesis was analyzed in recently formed alveolar tissue after tooth extraction in partially-pancreatectomized diabetic rats. The incorporation of alanine C14 was higher in diabetic animals than in treated diabetic and control groups. The results can be explained by a delay in bone tissue repair.
Skull growth is affected by numerous factors, including dentition. Animal experiments have assumed considerable importance in connection with such studies. This series of publications deals with the response of the skull skeleton and masticatory muscles to extraction of each emerging tooth in the right half of the jaws of Vietnamese belly pigs. The animals were slaughtered at various ages ranging from 6 to 12 months, throughout an important phase of post-natal skull development. Biomathematical methods were used to analyse the macerated skull and the masticatory musculature. Linear differential equations have proved useful for describing growth processes. The 1st report deals with the distances measured for the overall and rear skull, the orbita and the zygomatic arch. Differences between the right and left sides are slight with respect to these distances. Significant differences were found only in the range of the front part of the zygomatic arch during the 6th, 7th, 8th, 11th and 12th month of life.
High speed cinefluorography was used to track articulatory movements preceding and following full-mouth tooth extraction and alveolplasty in two subjects. Films also were made of a control subject on two separate days. The purpose of the study was to determine the effects of dramatically altering the structural dimensions of the oral cavity on the kinematic parameters of speech. The results showed that the experimental subjects performed differently pre and postoperatively though the changes were in different directions for the two subjects. Differences in both means and variabilities of kinematic parameters were larger between days for the experimental (operated) subjects than for the control subject. The results for the control subject also showed significant differences in the mean values of kinematic variables between days though these day-to-day differences could not account for the effects found pre- and postoperatively. The results of the kinematic analysis, particularly the finding that transition time was most stable over the experimental conditions for the operated subjects, are used to speculate about the coordination of normal speech.
Tooth extractions were carried out in 75 patients with haemophilia A after infusion of a single dose of cryoprecipitate and 4 g of epsilon-aminocaproic acid. During the 7-10 day period of follow-up, the patients received epsilon-aminocaproic acid by mouth. In 32 of 44 patients with severe or moderate haemophilia and in 22 of 31 patients with mild haemophilia, healing was uneventful and no bleeding complications occurred. Only in 5 patients with severe haemophilia and in 1 patient with mild heamophilia bleeding from tooth sockets was extensive enough to require further replacement therapy. The results show that epsilon-aminocaproic acid in conjunction with a single infusion of cryoprecipitate can insure hemostasis after dental extraction in patients with haemophilia A.
This study presents a histologic evaluation of the healing process of dental extraction sites in dogs with and without the use of collagen sponge as an extraction site dressing. The healing process was evaluated at 3 days, 1 week, and 6 months after tooth extraction and appears comparable in both collagen-filled and nonfilled extraction sites.

A tooth-grasping forceps with a gas-driven oscillating headpiece was designed for dental extractions in the dog, Compared with the conventional method, the extraction time was shortened considerably, and preliminary results indicate it may cause less trauma to alveolar bone and periodontal ligament.

A combination of fear and declining compensation may induce cardiovascular accidents in the elderly with heart disease. An accurate cardiac diagnosis and relief of stress and pain during tooth extraction are important. The range of cardiac abnormalities and the regime followed in two clinics in the People's Republic of China are reviewed, together with the precautions which are taken to avoid emergencies or manage them should they arise.
The terminal central nervous system distribution of those primary afferent neurons from the teeth and periodontium in cats was studied by degeneration methods. Lesions were created by combinations of tooth extractions and the brain stem was examined at 14, 30 and 60 days survival for degeneration patterns, with 30 days being the optimal survival time. Degenerating axons and terminals are seen bilaterally, but somewhat less on the side contralateral to the lesions and are concentrated in the ventral half of pars interpolaris and pars caudalis near obex. The results are discussed with regard to the current controversies concerning the primary central termination of these trigeminal neurons.
The effect of local irrigation of the gingival sulcus, which is considered an important source of bacteremia following dental procedures, with three different antiseptic solutions including hydrogen peroxide, chlorhexidine and povidone iodine, on the frequency of bacteremia after tooth extraction was determined, and the efficacies of the three antiseptics were compared. Although all the antiseptic solutions reduced the frequency of bacteremia to various degrees, povidone iodine was the most effective, and seemed to be the best choice since the decrease was statistically significant. Local administration of antiseptic solutions is therefore recommended as an adjuvant to systemic antibiotic prophylaxis.
The oral administration of 300 mg of clindamycin was undertaken on 23 patients, of 500 mg of cefadroxil on 11 patients and of 250 mg of talampicillin on 12 patients, and then tooth extraction was performed under local anesthesia. Blood samples were taken from the extraction wound and the peripheral vein at the same time and assayed by the bioassay method. The blood levels of clindamycin and cefadroxil indicated a similar pattern between the extraction wound and the peripheral vein, but the blood level of talampicillin reached peek level rapider than clindamycin and cefadroxil. The blood levels of the extraction wound were 60 - 80% as compared with the venous blood levels with each antimicrobial agent.

Three alpha chains of type V collagen--alpha 1 (V), alpha 2 (V), and alpha 3 (V)--were initially demonstrated together with the expected collagen types I and III in the pepsin-soluble fraction of both normal mandibular bone and tooth extraction wound tissues of rabbits, as analyzed by sodium dodecyl sulfate-gel electrophoresis. The total collagen content of each extraction wound, as determined by the hydroxyproline assay, was observed to increase continuously from day 5 through day 17 and then leveled off or decreased. The ratio of type V to type I collagen was significantly higher in the initial stage of wound healing and decreased sharply down to the level of mandibular bone by day 5. The ratio of type III to type I collagen in the pepsin-soluble fraction increased and reached a maximum on day 5, whereas it was maximal on day 7 in the cyanogen bromide-soluble fraction, and thereafter decreased gradually in both fractions. The ratio for the pepsin-soluble fraction was, however, significantly higher than that for the cyanogen bromide-soluble fraction in the early stage of wound healing.
All continuous teeth were unilaterally extracted on the right side of the upper and lower jaws of 57 male and female Vietnamese belly pig. The animals were slaughtered 6, 7, 8, 9, 10, 11 and 12 after the extraction. Our investigations into quantitative changes in the masticatory musculature after unilateral extraction showed the dry weight of the musculature on the extraction side was reduced. This reduction was greatest in the case of the M. temporalis. The findings relating to the muscles are consistent with the results of the skull evaluations reported in the first 2 publications, with indicated that tooth extraction leads to only local changes in the jaw during postnatal development. The findings published in the 3 publications of this series relating to the bones and muscles are discussed.
