“…All 3D surface models were manually cropped within 7 mm apical to the gingival margin area and distal to the first molar ( Figure 1 a). This soft-tissue area is the most relevant for the support of teeth or dental restorations and is expected to include the total height of keratinized gingiva [ 23 ], which are fixed to the underlying bone. The surface of the movable mucosa is not morphologically stable, and thus the proper scanning of this area with the current intraoral scanners is neither realistic nor accurate.…”

This study aimed to assess the reliability of two intraoral surface scanners for the representation of the alveolar process in vivo. Complete maxillary scans (CS 3600, Carestream and TRIOS 3, 3Shape) were repeatedly obtained from 13 fully dentate individuals. Scanner precision and agreement were tested using 3D surface superimpositions on the following reference areas: the buccal front teeth area, the entire dental arch, the entire alveolar process, or single teeth by applying an iterative closest point algorithm. Following each superimposition, the mean absolute distance (MAD) between predefined 3D model surfaces was calculated. Outcomes were analyzed through non-parametric statistics and the visualization of color-coded distance maps. When superimpositions were performed on the alveolar process, the median scanner precision was below 0.05 mm, with statistically significant but negligible differences between scanners. The agreement between the scanners was approximately 0.06 mm. When single-tooth superimpositions were used to assess the precision of adjacent alveolar soft-tissue surfaces, the median error was 0.028 mm, and there was higher agreement between the scanners. The in vivo reliability of the intraoral scanners in the alveolar surface area was high overall. Single-tooth superimpositions should be preferred for the optimal assessment of neighboring alveolar surface areas relative to the dentition.

“…In another study, the measurement was performed at the 1, 3, 5, and 7 mm levels below the bone crest for the teeth in the anterior maxilla 25 . One can suspect that some of the measurement levels, especially the level at the apical area, might be on the mobile tissue, considering the average height of KT in the anterior maxilla 27 …”

IntroductionThe changes in soft tissue profile following alveolar ridge preservation (ARP) with/without primary flap closure (PC) in periodontally damaged sockets have yet to be discovered.MethodsFor periodontally damaged non‐molar extraction sockets, ARP with PC (group PC)/without PC (group SC) was performed using granule‐type xenogeneic bone substitute material and a collagen barrier. Intraoral scans were performed at the time of ARP and 4 months thereafter. Superimposition of STL files was performed to examine tissue change on the soft tissue level. The level of mucogingival junction (MGJ) was also evaluated.ResultsA total of 28 patient (13 in group PC, 15 in group SC) completed the study. Soft tissue profile change was evaluated only when the measurement level was located on the non‐mobile tissue. Group PC tended to shrink less on the long axis of the extraction socket than group SC (−4.3 ± 3.1 mm vs. −5.9 ± 4.4 mm at the 1 mm below the pre‐extraction gingival margin, p > 0.05). Profilometric analysis (on the region of interest) also have a tendency of less tissue profile change in group PC than group SC (−1.0 ± 0.8 mm vs. −1.3 ± 0.5 mm, p > 0.05). The MGJ level change was not statistically significantly different between the groups (p > 0.05) even though the MGJ level was located more apically at 4 months in group SC compared with group PC.ConclusionsAlveolar ridge preservation with PC tended to yield less soft tissue shrinkage than ARP without PC.

“…Individuals presenting gingival bleeding compatible with gingivitis or evidence of periodontal pockets were excluded. The periodontal diagnosis was, in both cases, assessed through the measurements of probing depth, gingival height (measuring the height of keratinized and attached gingiva), 18 degree of tooth mobility, tooth loss, levels of clinical attachment alongside gingival index, 19 and plaque index. 20 Additionally, it was considered the presence of diabetes and smoking habits in light of their role as periodontitis grade modifiers.…”

“…Considering the outcome variables and based on the clinical evaluation, the patients were classified according to their periodontal status (healthy group and periodontally compromised group) and periodontitis staging according to the World workshop on the classification of periodontal and peri-implant diseases and conditions (stages I to IV). 1,2 Considering the exposure variables, the demographic variables collected were sex (female and male) and age, defined as the number of life years and recorded in an ordinal scale ( [18][19][20][21][22][23][24][25], [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45] and !46 years). The information on diabetes was collected based on the potential influence on the periodontal outcome.…”

Objectives A significant influence of the Herpesviridae family in the progression of periodontal disease has been suggested. The aim of this study was to investigate the potential association of four Herpesviruses (HSV-1, HSV-2, cytomegalovirus [CMV], and Epstein-Barr virus [EBV]) with periodontal disease using a qualitative test for evaluating the presence or absence of viral DNA in crevicular fluid samples of both healthy periodontal patients and periodontal compromised patients. Materials and Methods A case–control study was conducted in 100 participants at a university clinic. A qualitative test was used for evaluating the presence/absence of viral DNA in crevicular fluid samples of both healthy periodontal patients and periodontal compromised patients, and considering the periodontitis staging (stage II, stage III, and stage IV) and grading (grade A, grade B, and grade C). Statistical Analysis The distribution of the same exposure variables to the periodontitis staging and grading was compared using Chi-square, Fisher's exact, and Gamma tests depending on the variable characteristics. The significance level was set at 5%. The association of the variables: age, sex, diabetes, smoking, alcohol, and oral hygiene was also considered. Results The prevalence of Herpesviridae family virus DNA was 6% for the periodontal healthy group and 60% for the periodontitis group (roughly 60% on periodontitis stages II, III, and IV, p <0.001; and twofold increase in moderate and rapid progression grades compared with the slow progression grade, p <0.001). HSV1 DNA was prevalent in all periodontitis stages and grades. HSV 2, EBV, and CMV DNA had increasing prevalence rates in more severe stages (stages III and IV, p <0.001); while considering periodontitis grade, HSV2 (p = 0.001), CMV (p = 0.019) and EBV (p <0.001) DNA were prevalent only in grades B and C, with EBV DNA registering a marked prevalence in grade C. Conclusion A significant different distribution of Herpesviridae virus DNA per each stage of disease was registered.
