The observed difference in bone height between test and control sites in the surgical group after 12 months was less than 1 mm, which was only detectable on radiographs. No statistical difference was found on radiographs in the non-surgical group, where a decrease in bone height was found for both groups after scaling. Probing depth reduction after the surgical treatment, as well as after scaling and root planing, was as expected. Hyaluronan in contact with bone and soft tissues had no influence on the immune system in this study. Further studies are needed to determine the extent to which hyaluronan can lead to clinically significant healing of periodontal lesions.

“…Henrikson [15,16] has developed a technique for using 12"5I absorptiometry which measures bone mass at the same site just below the crest of the alveolar bone in humans at repeated times with a precision of 1 to 3%. This technique was used to follow humans longitudinally for the assessment of alveolar bone mass changes subsequent to periodontal surgery [ 17].In this study, the Henrikson technique of 125I absorptiometry [15,16] has been modified for use in measuring alveolar bone loss in ligature-related periodontitis in Macaca arctoides. The aims of this study were severalfold: (a) to follow the progression of alveolar bone loss at the same site over a period of time using 125I absorptiometry; (b) to determine the role of the gingival microflora on ligature-related bone loss: and (c) to determine whether ligature-related bone loss can be reversed.…”

Experimental alveolar bone loss in the monkey evaluated by125I absorptiometry

1979

An 125I absorptiometry technique is described which has sufficient precision to detect the alveolar bone loss associated with ligature-related periodontitis in the monkey. Six monkeys had significant drops in alveolar bone mass 14 days after the the application of a silk ligature around the gingival margin of an adjacent tooth. Variation in the magnitude of bone loss was observed. These may represent variations in the pathogenicity of the microflora produced in response to a ligature and/or variation in host response to the insult produced by specific dental plaque organisms. The lack of bone loss post-ligature plus antibiotic therapy supports the theory that the bacterial-host interaction, not simply irritation from the ligature alone, is responsible for the bone loss. The potential for bone regeneration after ligature-induced bone loss is demonstrated.

“…15 The incisions can be extended any time, favoring a better elasticity of the flap, and still facilitate flap repositioning after removal of the third molar. 18 A wide and divergent incision to the fornix guarantees good vascularization to the flap margins. 22 However, dehiscence of sutured borders is common when the incision lies over the mucosa that covers the impacted tooth, because a bone defect will remain in this area, giving no support to the mucoperiosteal flap.…”

“…10,17 Dehiscence in the distal margin of the second molar during the first phase of healing is another frequent complication when using these types of flaps. 14,16,18 On the other hand, the alternative technique described in this study shows that it is possible to optimally preserve bone structures and, through the vertical flap, respect the basic surgery premises, which suggest that the incision must be done upon intact tissue, and the flap must lay on healthy bone tissue. 19 The aim of this study was to compare 2 surgical access flaps evaluating clinical limitations of the alternative procedure used for removal of impacted lower third molars during primary wound healing period.…”
