La Rosa GRM, Chapple I, Polosa R, Pedullà E. A scoping review of new technologies for dental plaque quantitation: Benefits and limitations. J Dent 2023; 139:104772. [PMID: 37939996 DOI: 10.1016/j.jdent.2023.104772] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Revised: 10/29/2023] [Accepted: 11/02/2023] [Indexed: 11/10/2023] Open
Abstract
OBJECTIVES To determine the validity and reliability of novel digitalized tools for dental plaque detection and explore the benefits and limitations connected to their use. DATA Reporting followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Extension for Scoping Reviews. All human clinical studies comparing dental plaque detection using digitalized systems against a standard reference were included. SOURCES PubMed and Scopus were screened from 01 January 2013 to 28 September 2023. Bibliographies of primary studies and principal peer-reviewed scientific journals were manually searched. STUDY SELECTION The initial search identified 576 articles, with a total of 13 included in the review, published between 2015 and 2023. Most of the studies included (77 %) were cross-sectional with three being prospective. Digital devices captured 2D and 3D images via cameras and intra-oral scanners, respectively. The Turesky's modified plaque index was the most frequent clinical index. Correlation with clinical examination was moderate to strong, with good to excellent intra- and inter-system agreement. CONCLUSIONS Within the limitations of this scoping review, image analysis-based plaque detection systems demonstrated good correlations with clinical plaque indices, using both 2D and 3D imaging systems. Whilst digital plaque detection devices offer advantages in terms of procedural standardization and reproducibility, they also have limitations, therefore currently, their application should be underpinned by a comprehensive clinical examination. CLINICAL SIGNIFICANCE Digital plaque detection tools, that provide standardized measurements and store acquired images, facilitate more informed feedback to patients. This objective analysis may enhance clinician confidence in their utility for clinical trials and other applications.

Efficacy of hyaluronic acid gel and photobiomodulation therapy on wound healing after surgical gingivectomy: a randomized controlled clinical trial. BMC Oral Health 2023; 23:805. [PMID: 37891549 PMCID: PMC10612174 DOI: 10.1186/s12903-023-03519-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Accepted: 10/10/2023] [Indexed: 10/29/2023] Open
Abstract
BACKGROUND Surgical gingivectomy can be considered the gold standard treatment for gingival enlargement. The healing of wound site after gingivectomy occurs slowly by secondary intention. To accelerate the wound healing process, several studies have been conducted evaluating the effect of various treatment modalities. Photobiomodulation therapy (PBMT) was proposed to provide minimally invasive and painless treatment as well as to decrease discomfort of the patient following the surgical process. Another factor that is expected to improve the healing after surgery is topical application of chemotherapeutic agents such as Hyaluronic acid (HA). This study aims to assess the effect of topically applied HA gel after PBMT on the healing of wound site after surgical gingivectomy. METHODS This randomized controlled clinical trial included twenty-six surgical gingivectomy wound sites, equally divided into two groups, Group-I (test group): the surgical sites after gingivectomy were irradiated with a diode laser (980 nm, 0.2 W) then covered by 2% HA gel loaded in a special custom-made soft transparent tissue guard appliance for each patient. Group II (control group): the surgical sites were irradiated with a diode laser (980 nm, 0.2 W) only. Wound healing was assessed subjectively by Landry healing index on the 3rd, 7th, 14th and 21st days after surgery, and pain perception was assessed by the patients using visual analog scale (VAS) throughout the 21 days of the follow up period. Comparisons between the two study groups were performed using Mann-Whitney U test, while comparisons between different time points were performed using Friedman test. Significance was inferred at p value < 0.05. RESULTS By the end of the follow-up period, surgical sites of the test group showed excellent healing compared to the control group. There were no significant differences in VAS scores between both groups (p > 0.05). CONCLUSIONS Application of 2% HA gel as an adjunctive to PBMT was found to have significant clinical effects and higher power of repair among test group when compared to that achieved by PBMT alone in control group. TRIAL REGISTRATION This study was retrospectively registered on ClinicalTrials.gov and first posted on 28th of March 2023 with an identifier number: NCT05787912.

Dent J (Basel) 2023; 11:172. [PMID: 37504238 PMCID: PMC10378657 DOI: 10.3390/dj11070172] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Revised: 07/09/2023] [Accepted: 07/14/2023] [Indexed: 07/29/2023] Open
Abstract
Dental plaque is a biofilm structured in an extracellular matrix of polymers of host and microbial origin; the microorganisms can coexist in harmony with the host, thus guarantying oral health. Environmental modifications can lead to dysbiosis and onset of oral diseases; in fact, plaque is the etiological agent both of periodontal disease and dental decay. The use of an effective oral hygiene index should be considered as a relevant goal for the clinicians and the researchers, and consequently, numerous plaque indices have been proposed during the years. The present literature review aims primarily to obtain a complete summary of these scores to assess plaque deposits. It is useful because the clinician/researcher will select the right scoring method for the specific situation only if he knows the available options and if he is aware of both their strengths and weaknesses. This review applies a basic classification of plaque indices that distinguishes the ones that use non-quantitative methods from the ones that use quantitative methods. Non-quantitative methods are more subjective because they are based on the ability of the clinician to point out the presence or the entity of deposits, while quantitative methods introduce objectifiable means to measure plaque deposits.

Abstract
AIM: This study compared the effect of traditional and virtual oral hygiene instruction to school health instructors on plaque index (PI) of elementary schoolchildren.
METHODS AND MATERIALS: In this descriptive, analytical study, 66 elementary schools in Kermanshah city were selected by cluster sampling. The school health instructors first participated in a pretest and filled out a questionnaire. The O’Leary’s index of 339 elementary schoolchildren was measured at baseline. Next, the school health instructors received oral hygiene instructions in two groups (n = 33) of virtual instruction through an online course and traditional classroom setting. After 3 weeks, a post-test was held and school health instructors filled out the same questionnaire for the 2nd time. After 3 months, the PI of students was measured again. Data were analyzed using the Chi-square test, t-test, Mann–Whitney U-test, and ANOVA.
RESULTS: Both instruction methods significantly enhanced the oral hygiene knowledge of instructors (p < 0.001) but virtual instruction was significantly more effective (p = 0.02). No significant association was noted between age, work experience of instructors, or their level of education with their knowledge level in the virtual group (p > 0.05). An inverse correlation was noted between age and work experience of instructors with their knowledge level in the traditional instruction group (p < 0.05). Both instruction methods caused significant improvement of PI of students (p < 0.001) but virtual instruction was more effective (p < 0.001).
CONCLUSION: Correct oral hygiene instruction to school health instructors (preferably by virtual instruction) can reduce PI elementary schoolchildren.

Abstract
Different types of internal implant-abutment connections, namely hexagon and conical, have been used for implant restoration. However, data regarding the benefits of these internal connections in terms of clinical outcomes are scarce. Accordingly, the aim of this study was to compare radiographic marginal bone loss (RMBL) and associated implant complications between implants with internal hexagon (IH) connections and those with internal conical (IC) connections. Forty-nine patients with 98 implants (two per patient) placed in the posterior mandible were recruited. All implants were inserted in pairs in solid D2 bone according to a randomized sequence; the first patient received an IH connection implant on the mesial side while the second patient received an IC connection implant on the mesial side. Each patient received one implant with an IH connection and one with an IC connection, placed side-by-side. Four months after placement, all implants were loaded with single screw-retained ceramic restorations with internal hexagon or conical connections. RMBL and complications, including implant/prosthesis failure, were recorded at the time of implant loading (baseline) and 6, 12, and 36 months after loading. The results revealed no significant between-group differences in RMBL (P = .74), gingival bleeding on probing (P = .29), and complications (P = .32). Thus, the type of internal implant-abutment connection did not affect clinical outcomes, including RMBL and implant/prosthesis failure. Future studies should additionally evaluate long-term prosthesis-related complications such as screw loosening and fracture between the two types of internal connections.

Abstract
Aims Higher intakes of fruits and vegetables, and vitamin C are associated with improved periodontal healing post‐scaling and root planing (SRP). This study determined if this association was sustained at 3–4 years post‐SRP, and if flavonoid intake is associated with periodontal health. Whether reduced probing depth (PD) is sustained and whether PD is correlated with salivary IL‐1β, IL‐6 and CRP at 3–4 years post‐SRP were also studied. Materials and Methods Clinical periodontal outcomes, dietary intakes and salivary markers of inflammation were measured in patients (n = 43, 23 females, 37–93 years) who had undergone SRP 3–4 years earlier and had been part of a periodontal maintenance programme. Results Flavonoid intake was inversely associated with PD (p = .042) and salivary IL‐1β concentration (p = .015) after adjustment for multiple confounders. When changes in PD were considered, the association of flavonoid intake with reduced PD became borderline significant (p = .051) but persisted for IL‐1β (p = .018). PD at 3–4 years and 2–4 months post‐SRP was similar. There was a positive correlation between PD and salivary IL‐1β (p = .005) but not with salivary CRP and IL‐6. Conclusion Higher flavonoid intake is associated with lower IL‐1β. Also, regular supportive periodontal therapy maintained the improved PD at 3–4 years post‐SRP regardless of smoking status.

Abstract
The optimal frequency of tooth brushing in the critically ill has not been experimentally determined. For mechanically ventilated patients, optimal frequency of tooth brushing is an important unresolved issue as there is little evidence to judge the benefits or associated risks of tooth brushing. Given this knowledge gap, the project's overall goal is to determine the optimal frequency of tooth brushing (once, twice, or three times daily) for mechanically ventilated adults. A prospective, randomized, experimental design is used. Specifically, 345 subjects, with 207 expected to complete the study, are randomly assigned within 36 hr of intubation to one of three groups (once, twice, or three times tooth brushing daily). Tooth brushing with a soft compact-head toothbrush takes approximately 2 min. Dental plaque assessment, gingival crevicular fluid (GCF) determination for IL-1β, and data regarding healthcare-acquired infection (HAI) and clinical status are collected at baseline and daily in-hospital. The clinical impact of daily frequency of tooth brushing in relation to extent of dental plaque and inflammation reflected by GCF analysis will be compared by the three treatment arms. In addition, evaluation of safety for HAIs will be compared based on calculation of the number needed to harm. The trial will empirically determine the optimal frequency of tooth brushing in mechanically ventilated adults, balancing benefits and risks. This contribution is significant because it will have immediate impact on bedside nursing practice, and is a final component necessary for specific evidence-based guidelines for the common nursing intervention of oral care in mechanically ventilated adults.

A proposed new index for clinical evaluation of interproximal soft tissues: the interdental pressure index. Int J Dent 2014; 2014:345075. [PMID: 24799903 PMCID: PMC3995173 DOI: 10.1155/2014/345075] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2014] [Accepted: 03/10/2014] [Indexed: 11/21/2022] Open
Abstract
The interdental pressure index (IPI) is introduced to specifically evaluate clinical interproximal-tissue conditions and assess the effect of interproximal hygiene stimulation. This index scores clinical responses of periodontal tissues to the apical pressure of a horizontally placed periodontal probe. It is negative when gingival tissues are firm, bleeding-free, and slightly ischemic by the stimulation; otherwise it is positive. The clinical validation showed high intraoperator agreement (0.92; 95% CI: 0.82–0.96; P = 0.0001) and excellent interoperator agreement (0.76; 95% CI: 0.14–1.38; P = 0.02). High internal consistency with bleeding on probing (κ = 0.88) and gingival index (Cronbach's α = 0.81) was obtained. Histological validation obtained high sensitivity (100%) and specificity (80%) for IPI+ toward inflammatory active form. The same results were recorded for IPI− toward chronic inactive form. IPI results as a simple and noninvasive method with low error probability and good reflection of histological condition that can be applied for oral hygiene motivation. Patient compliance to oral hygiene instructions is essential in periodontal therapy and IPI index can be a practical and intuitive tool to check and reinforce this important aspect.

Abstract
OBJECTIVE The purpose of this study was to describe the pattern of dental plaque accumulation in mechanically ventilated adults. Accumulation of dental plaque and bacterial colonisation of the oropharynx is associated with a number of systemic diseases including ventilator associated pneumonia. RESEARCH METHODOLOGY/DESIGN Data were collected from mechanically ventilated critically ill adults (n=137), enrolled within 24 hours of intubation. Dental plaque, counts of decayed, missing and filled teeth and systemic antibiotic use was assessed on study days 1, 3, 5 and 7. Dental plaque averages per study day, tooth type and tooth location were analysed. SETTING Medical respiratory, surgical trauma and neuroscience ICU's of a large tertiary care centre in the southeast United States. RESULTS Plaque: all surfaces >60% plaque coverage from day 1 to day 7; molars and premolars contained greatest plaque average >70%. Systemic antibiotic use on day 1 had no significant effect on plaque accumulation on day 3 (p=0.73). CONCLUSIONS Patients arrive in critical care units with preexisting oral hygiene issues. Dental plaque tends to accumulate in the posterior teeth (molars and premolars) that may be hard for nurses to visualise and reach; this problem may be exacerbated by endotracheal tubes and other equipment. Knowing accumulation trends of plaque will guide the development of effective oral care protocols.

Abstract
OBJECTIVE Transient bacteremia occurs in healthy populations from toothbrushing. With the high incidence of bacteremia in the intensive care unit and toothbrushing as an oral care method, this study examined the incidence and clinical significance of transient bacteremia from toothbrushing in mechanically ventilated adults. METHODS Prospective pre- and post-test with all subjects (N = 30) receiving a toothbrushing intervention twice per day (up to 48 hours). The planned microbial analysis used DNA typing to identify organisms from oral and blood cultures collected immediately before, 1 minute, and 30 minutes after the interventions. RESULTS Seventeen percent of subjects had oral cultures that were positive for selected pathogens before the first toothbrushing intervention. None of the subjects had evidence of transient bacteremia by positive quantitative blood cultures before or after the toothbrushing interventions. Patient characteristics were not statistically significant predictors for systemic inflammatory response syndrome, length of hospital stay, or length of intubation. CONCLUSION The toothbrushing intervention did not induce transient bacteremia in this patient population.

Abstract
The primary purposes of this descriptive and prospective pilot study was to test the feasibility of a nursing and dental hygiene team to measure specific oral health indices in a sample of older adults residing in nursing homes (NHs). The secondary purpose was to determine the relationship between plaque and dentate status. Oral health indicators, functional status scores, and behavioral scores were collected and analyzed from 38 female NH residents from two geographically, organizationally, and economically diverse NHs. Persons with dentures had significantly lower plaque scores than those with natural dentition. Rural NH residents and African American NH residents had fewer filled teeth, indicating a potential lack of access to dental care. Oral health indicators were collected safely and efficiently from NH residents using a nursing and dental hygiene collaborative approach. Nursing and dental hygiene collaborations hold promise for improving the oral health in institutionalized elders.

Abstract
Aims In studying aetiological interactions of genetic, epigenetic and environmental factors in normal and abnormal developments of the dentition, methods of measurement have often been limited to maximum mesio-distal and bucco-lingual crown diameters, obtained with hand-held calipers. While this approach has led to many important findings, there are potentially many other informative measurements that can be made to describe dental crown morphology. Advances in digital imaging and computer technology now offer the opportunity to define and measure new dental phenotypes in 3-D that have the potential to provide better anatomical discrimination and clearer insights into the underlying biological processes in dental development. Over recent years, image analysis in 2-D has proved to be a valuable addition to hand-measurement methods but a reliable and rapid 3-D method would increase greatly the morphological information obtainable from natural teeth and dental models. Additional measurements such as crown heights, surface contours, actual surface perimeters and areas, and tooth volumes would maximise our ability to discriminate between samples and to explore more deeply genetic and environmental contributions to observed variation. The research objectives were to investigate the limitations of existing methodologies and to develop and validate new methods for obtaining true 3-D measurements, including curvatures and volumes, in order to enhance discrimination to allow increased differentiation in studies of dental morphology and development. The validity of a new methodology for the 3-D measurement of teeth is compared against an established 2-D system. The intra- and inter-observer reliability of some additional measurements, made possible with a 3-D approach, are also tested. Methods and results From each of 20 study models, the permanent upper right lateral and upper left central incisors were separated and imaged independently by two operators using 2-D image analysis and a 3-D image analysis system. The mesio-distal (MD), labio-lingual (LL) and inciso-gingival (IG) dimensions were recorded using our 2-D system and the same projected variables were also recorded using a newly developed 3-D system for comparison. Values of Pearson's correlation coefficient between measurements obtained using the two techniques were significant at the 0.01 probability level for variables mesio-distal and incisal-gingival with labio-lingual significant at the 0.05 level for the upper left side only, confirming their comparability. For both 2-D and 3-D systems the intra- and inter-operator reliability was substantial or excellent for variables mesio-distal, labio-lingual, incisal-gingival actual and projected and actual surface area. The reliability was good for inter-operator reliability measurement of the labio-lingual dimension using 3-D. Conclusions We have developed a new 3-D laser scanning system that enables additional dental phenotypes to be defined. It has been validated against an established 2-D system and shown to provide measurements with excellent reliability, both within and between operators. This new approach provides exciting possibilities for exploring normal and abnormal variations in dental morphology and development applicable to research on genetic and environmental factors.

Abstract
OBJECTIVES To analyze a possible association between glutathione-S-transferase T1 (GSTM1) and/or glutathione-S-transferase M1 (GSTM1) polymorphisms and chronic or aggressive forms of periodontitis in a Caucasian ethnic group. DESIGN AND METHODS Sixty-nine chronic, 14 aggressive periodontitis and 61 controls, deeply analyzed from a clinical point of view, were studied for their GSTM1 and GSTT1 polymorphisms by allelic specific PCR techniques. As a second control group, 64 blood donors were also included. RESULTS A significant association was found between GSTM1-null genotype and both chronic and aggressive periodontitis. The aggressive forms were associated with the double null GSTM1 and GSTT1 combination. These results were independent of the patients' age, gender, hygienic habits and smoke (evaluated as tobacco smoking yes/no, cigarettes/day and pack years) as confirmed by multivariate logistic regression analysis. CONCLUSIONS The GSTM1-null variant is statistically associated with the two forms of periodontitis, while the aggressive one also presents a second null variant: GSTT1.

Abstract
Oral health can impact general health and systemic disease. Changes in dental plaque, oral microbial flora, and local oral immunity may be important in the development or exacerbation of disease in critically ill patients, trauma patients, adults with chronic obstructive pulmonary disease, and frail elderly. Inasmuch as oral health potentially can be influenced by nursing interventions, nursing research in this area can contribute greatly to improved patient outcomes in these diverse populations. The authors' research teams have conducted several federally funded projects focused on oral health and have developed synergy in research methods. A unifying theme for these research projects is the measurement of oral health. Standardized measures of components of oral health are available and applicable across populations, and their uses and relationship to nursing research and patient outcomes will be discussed.

Abstract
AIM The aim of this study was to increase the versatility and further validate the method reported by Smith et al. (2001) by testing the reliability of plaque measurement against two well-known dental plaque quantification methodologies using image analysis in a clinical trial. METHOD The teeth of 40 subjects were disclosed before digital images of the labial and lingual surfaces of their upper and lower incisors were acquired. The amount of plaque present was quantified using a modification of the method described by Smith et al. (2001). The method was modified for obtaining images of the lingual surfaces by incorporating the use of orthodontic occlusal mirrors and 5-mm pieces of moistened blue articulating paper used to enable calibration. Plaque measurements were made from 320 upper and lower anterior teeth from the 40 subjects by two operators. Fliess' coefficient of reliability was used to assess intra- and inter-operator reliability and the independent sample t test was used to assess statistical significance between test and control groups after checking the data for normality. For validation, measurements were recorded using the Turesky et al. (1970) (modification of the Quigley & Hein (1962) plaque index and the Addy et al. (1983) plaque area index. The results were compared with the image analysis method using Pearson's correlation coefficient. RESULTS The results for reliability were within Fliess' range of "excellent" for both intra-operator repeatability and inter-operator reproducibility. Pearson's correlation coefficients showed highly significant values indicating the close similarity between all three methods. CONCLUSIONS This method for the measurement of dental plaque on lingual surfaces of anterior teeth proved reliable. The combined results from the labial and lingual surfaces of anterior teeth using image analysis produced trial conclusions comparable with the alternate plaque quantification methods used, with less clinician time and further producing a permanent database of images for future use.
