This study aimed at determining the correlation between gingival stippling (GS) and other phenotypical characteristics. Adult subjects in need of cone-beam computed tomography scans (CBCT) and comprehensive dental treatment in the maxillary anterior region were recruited. Facial gingival thickness [GT] and buccal bone thickness [BT] were assessed utilizing CBCT. Standardized intraoral photographs were obtained to determine keratinized tissue width (KTW), presence of GS in all facial and interproximal areas between the maxillary canines, and other variables of interest, such as gingival architecture (GA), tooth shape, and location. Statistical analyses to assess different correlations among recorded variables were conducted. A total of 100 participants and 600 maxillary anterior teeth constituted the study population and sample, respectively. Facial GS was observed in 56% of males and 44% of females, and it was more frequently associated with flat GA, triangular and square/tapered teeth, central incisors, and males. Greater mean values of GT, BT, and KTW were observed in facial areas that exhibited GS. Interdental GS was present in 73% of the sites and it was more frequently observed in males, the central incisor region, and when facial GS was present. Multilevel logistic regression revealed a statistically significant association between the presence of GS and KTW, BT measured at 3mm apical to the bone crest, and tooth type. This information can be used in the recognition of common periodontal phenotypical patterns associated with specific features of great clinical significance. 

The aim of this PRISMA-compliant systematic review was to analyze the evidence pertaining to disease resolution after treatment of peri-implant diseases (PROSPERO: CRD42022306999) with the following PICO question: what is the rate of disease resolution following non-surgical and surgical therapy for peri-implant diseases in adult human subjects? A literature search to identify studies that fulfilled a pre-established eligibility criteria was conducted. Data on primary therapeutic outcomes, including treatment success, rate of disease resolution and/or recurrence, as well as a variety of secondary outcomes was extracted and categorized. Fifty-five articles were included. Few studies investigated the efficacy of different non-surgical and surgical therapies to treat peri-implant diseases using a set of pre-defined criteria and with follow-up periods of at least one year. The definition of treatment success and outcomes of disease resolution differed considerably among the included studies. Treatment of peri-implant mucositis was most commonly reported to be successful in arresting disease progression for ≤60% of the cases, whereas most studies on peri-implantitis treatment reported disease resolution occurring in <50% of the fixtures. In conclusion, disease resolution is generally unpredictable and infrequently achieved after the treatment of peri-implant diseases. A great variety of definitions have been used to define treatment success. Notably, percentages of treatment success and disease resolution were generally underreported. The use of standardized parameters to evaluate disease resolution should be considered an integral component in future clinical studies.

This study aimed at characterizing the gingival thickness (GT) and determining correlations with other local phenotypical features. Cone-beam computed tomography scans from adult subjects involving the maxillary anterior teeth were obtained to assess buccal GT at different apico-coronal levels, periodontal supracrestal tissue height (STH), the distance from the cementoenamel junction to the alveolar bone crest (CEJ-BC), and bucco-lingual tooth dimensions in mm. A total of 100 subjects and 600 maxillary anterior teeth constituted the study sample. Variations in mean values of GT were observed as a function of apico-coronal level, tooth type, and gender. GT progressively increased apically. Maxillary central incisors and males generally exhibited thicker GT. Contrarily, females exhibited thinner GT and shorter STH. Tooth dimensions were negatively correlated with GT, as the narrower the tooth crown/root in the bucco-lingual dimension, the thicker the gingiva. GT at the level of the CEJ was dichotomized to differentiate between thin (<1mm) and thick (≥1mm) gingival phenotypes (GP). Teeth with a thin GP displayed greater CEJ-BC and buccolingual tooth width dimensions. Conversely, teeth with a thick GP generally exhibited taller STH and narrower tooth dimensions.

This PRISMA-compliant systematic review aimed to investigate the effect of supportive peri- implant care (SPIC) on peri-implant tissue health and disease recurrence following the non surgical and surgical treatment of peri-implant diseases. The protocol of this review was registered in PROSPERO (CRD42023468656). A literature search was conducted to identify investigations that fulfilled a set of pre-defined eligibility criteria based on the PICO question: what is the effect of SPIC upon peri-implant tissue stability following non-surgical and surgical interventions for the treatment of peri-implant diseases in adult human subjects? Data on SPIC (protocol, frequency, and compliance), clinical and radiographic outcomes, and other variables of interest were extracted and subsequently categorized and analyzed. A total of 8 studies, with 288 patients and 512 implants previously diagnosed with peri-implantitis were included. No studies including peri-implant mucositis fit the eligibility criteria. Clinical and radiographic outcomes were similar independently of specific SPIC features. Nevertheless, a 3-month recall interval was generally associated with a slightly lower percentage of disease recurrence. The absence of disease recurrence at the final follow-up period (mean of 58.7±25.7 months) ranged between 23.3% and 90.3%. However, when the most favorable definition of disease recurrence reported in the selected studies was used, mean disease recurrence was 28.5% at baseline, considered 1 year after treatment for this investigation, and increased to 47.2% after 2 years of follow-up. In conclusion, regardless of the SPIC interval and protocol, disease recurrence tends to increase over time after the treatment of peri-implantitis, occasionally requiring additional interventions.

The primary aim of this study was to evaluate the efficacy of alveolar ridge preservation (ARP) ther- apy compared with unassisted socket healing (USH) in attenuating interproximal soft tissue atrophy. Adult patients who underwent maxillary single-tooth extraction with or without ARP therapy were included. Surface scans were obtained and CBCT was performed to digitally assess interproximal soft tissue height changes and measure facial bone thickness (FBT), respectively. Logistic regres- sion models were conducted to investigate the individual effect of demographic and clinical vari- ables. Ninety-six subjects (USH = 49; ARP = 47) constituted the study population. Linear soft tissue assessments revealed a significant reduction of the interproximal soft tissue over time within and between groups (P < .0001). ARP therapy significantly attenuated interproximal soft tissue height re- duction compared to USH: –2.0 ± 0.9 mm mesially for USH vs –1.0 ± 0.5 mm mesially for ARP; –1.9 ± 0.7 mm distally for USH vs –1.1 ± 0.5 mm distally for ARP (P < .0001). Thin (≤ 1 mm) facial bone thick- ness (FBT) upon extraction was associated with greater interproximal soft tissue atrophy compared to thick FBT (> 1 mm), independent of the treatment received (P < .0001). Nevertheless, ARP therapy resulted in better preservation of interproximal soft tissue height, especially in thin bone phenotype, by a factor of 2 for the mesial site (+1.3 mm) and by a factor of 1.6 for the distal site (+0.9 mm). This study demonstrated that ARP therapy largely attenuates interproximal soft tissue dimensional re- duction after maxillary single-tooth extraction compared to USH.

Clinicians, researchers, and policymakers often rely on the available scientific evidence to make strategic decisions. Systematic reviews (SRs) occupy an influential position in the hierarchy of scientific evidence. The findings of wellconducted SRs may provide valuable information to answer specific research questions^1,2 and identify existing gaps for future research.³ Therefore, it is of supreme importance that SRs are published promptly, reducing as much as possible the time elapsed between the last date of the search for primary studies and the actual publication date. A study published in 2014 assessed the publication delay of SRs in orthodontics, revealing that the median time interval from the last search to publication was more than 1 year (13.2 months).⁴ Delays in the publication of SRs or original research articles may depend on author-related factors (eg, timing of resubmission after receiving feedback from reviewers) or journal-related factors (eg, time taken to process a submission).^5–7 Regardless of the reasons, clinical recommendations and translation of SR findings may be affected by publication delay. We assessed the extent of publication delay of systematic reviews in dentistry with the purpose of addressing its implications and presenting potential solutions.

Purpose: To establish consensus-driven guidelines that could support the clinical decision-making process for implant-supported rehabilitation of the posterior atrophic maxilla and ultimately improve long-term treatment outcomes and patient satisfaction. Materials and methods: A total of 33 participants were enrolled (18 active members of the Italian Academy of Osseointegration and 15 international experts). Based on the available evidence, the development group discussed and proposed an initial list of 20 statements, which were later evalu-ated by all participants. After the forms were completed, the responses were sent for blinded ana-lysis. In most cases, when a consensus was not reached, the statements were rephrased and sent to the participants for another round of evaluation. Three rounds were planned. Results: After the first round of voting, participants came close to reaching a consensus on six statements, but no consensus was achieved for the other fourteen. Following this, nineteen statements were rephrased and sent to participants again for the second round of voting, after which a consensus was reached for six statements and almost reached for three statements, but no consensus was achieved for the other ten. All 13 statements upon which no consensus was reached were rephrased and included in the third round. After this round, a consensus was achieved for an additional nine statements and almost achieved for three statements, but no consensus was reached for the remaining statement. Conclusion: This Delphi consensus highlights the importance of accurate preoperative planning, taking into consideration the maxillomandibular relationship to meet the functional and aesthetic requirements of the final restoration. Emphasis is placed on the role played by the sinus bony walls and floor in providing essential elements for bone formation, and on evaluation of bucco-palatal sinus width for choosing between lateral and transcrestal sinus floor elevation. Tilted and trans-sinus implants are considered viable options, whereas caution is advised when placing pterygoid implants. Zygomatic implants are seen as a potential option in specific cases, such as for completely edentulous elderly or oncological patients, for whom conventional alternatives are unsuitable.
