“…Many studies show that after removal of the mandibular third molar, there will be an injury to the distal aspect of the second molar, and it is still indicated as successful treatment. [10][11][12] Recently, piezosurgery has been invented to perform safe and precise surgeries. 13 To standardize our results, it was conducted on 30 male individuals having their age ranging from 25 to 33 years, in order to remove the gender factor that may play a role in postoperative complications due to hormonal changes that may occur in females.…”

Introduction: Bone removal is necessary for extracting the third molars that are erupted, partially erupted, and/or impacted in bone. Hence, it is necessary to choose a surgical method or instruments that conform to anatomic landmarks and are based on physiological principles. Many authors have reported injuries to the adjacent tooth, especially the distal part of periodontium after removal of second molar. Hence, the present study was undertaken to assess and compare the surgical and postsurgical outcomes of third molar removal using piezoelectric surgery and rotary bur. Materials and methods:A total of 30 healthy adult individuals who were in need of prophylactic removal of impacted mandibular third molar tooth with ideal condition were included for the study. Individuals were divided randomly into study groups of 15 each, so that the difficulty of surgery will be the same in both the groups. Group I -piezoelectric osteotomy technique and group II -rotary osteotomy technique. The rotary device consists of a hand piece and a rotary speed ranging around 35,000 rpm was used. The piezoelectric device consists of a hand piece, and a frequency of 25 to 29 kHz with a microvibration of 60 to 200 mm/sec was used with a boosted working mode. Data were analyzed using unpaired t-test and qualitative data were analyzed using Fischer's exact test.

“…The radiographic techniques utilized were also different in those studies. Furthermore, they did not use the same methods of measurement and calibration, [18][19][20][21][22][23][24][25][26][27][28][29] nor did the majority of them evaluate the error of their radiographic technique. [19][20][21][22][23][24][25][26] Krausz et al 27 twice performed linear computerized measures of bone defects in panoramic radiographs, with minutes between them initially and 12 months later; the error between these evaluated measures was about 5% (r 2 5 95%).…”

“…They were able to conclude that repeated radiographic registrations of the 2 Mm region, using their technique, could be performed with accuracy. 7,[28][29][30] In this study all of the radiographic measurements were performed three times, for the purpose of statistically validating their accuracy and repeatability. All the measures were made by a single operator (AF) avoiding possible interexaminer error.…”

Objectives: The purpose of this study was to investigate the repeatability and radiographic accuracy of an intraoral paralleling technique to evaluate periodontal bone healing on the distal surface of the second mandibular molar (2 Mm) after impacted third mandibular molar (3 Mm) surgical extraction. Methods: In order to estimate the variation in different radiographs, three replicas were made, each from 2 Mm, totalling 69 radiographic radicular longitude (RRL) recordings. One operator performed the periapical radiographs in a standard manner, utilizing a modified posterior film holder for the radiographic technique of parallelism, applied on the posterior region with the X-ray beam focused on the centre of 2 Mm. These radiographic recordings of the same region were obtained on three different and separate occasions, over a 12 month evaluation period after surgical extraction of the impacted 3 Mm. The RRL variable was measured and recorded three times by the same operator, with side-by-side comparison of three posterior periapical radiographs, irrespective of when the assessments were performed. Results: There were no statistically significant differences between the three replica recordings (p 5 0.969). The correlations between the three sets of measurements were evaluated and found to be highly associated (intraclass correlation reliability coefficient 5 0.90) and statistically significant (p#0.05). The median and mean error of the radiographic technique evaluated was ¡0.257 mm and ¡0.347 mm, respectively. Conclusions: The radiographic technique described permits standardization in periapical radiographs with a high repeatability and accuracy in posterior radiographic records (distal surface of 2

“…1 Moreover, the alveolar bone loss on the distal side of the second molar has been well described in horizontal impacted third molar, regardless of the presence of AP. [2][3][4][5][6][7] On the other hand, a correlation between the infl ammatory infi ltrate and histological alveolar bone loss has been observed, 8 and endothelial-derived cytokines, 9 T cells, [10][11][12][13] mast cells, 14 and interleukin-1 (IL-1) 15,16 may be involved in bone resorption. Hou and colleagues 17 noted that intact Toll-like receptor (TLR) function mediates increased proinfl ammatory responses and bone destruction in response to mixed anaerobic infections, while there is a reduction of bone destruction in TLR4- 17 and TLR2-defi cient mice.…”

Acute pericoronitis (AP) arises frequently in incompletely impacted mandibular third molars, but it remains unknown whether bone resorption in aging is associated with acute infl ammation of the third molar. We conducted an experiment to compare the ratio of bone resorption to root length in the distal surface of the second molar (A), the proximal surface (B), and distal surface (C) in mesio-angular, incompletely impacted third molars in 27 young and 58 older adults with AP and 77 young and 79 older adults without a history of AP. Bone resorption in A, B, and C in older adults with AP demonstrated a signifi cantly higher ratio when compared to those without AP, whereas there was no difference between those with and without AP in young adults except for B in women. However, there were no differences between bone resorption in B with AP in young and older women, and between bone resorption in C with AP in young and older adults. These indicate that AP and bone resorption are associated with incompletely impacted mandibular third molars in older adults.
