Objectives The study aimed to clinically assess the association between periodontitis and COVID-19-related outcomes. Material and methods Data pertaining to patient demographics, medical history, blood parameters, periodontal clinical examination and aMMP-8 point-of-care diagnostics (both site-level and patient-level) was recorded for eighty-two COVID-19positive patients. COVID-19-related outcomes such as COVID-19 pneumonia, death/survival, types of hospital admission and need of assisted ventilation were also assessed. Results Males were predominantly afflicted with COVID-19, with advanced age exhibiting a greater association with the presence of periodontitis. Higher severity of periodontitis led to 7.45 odds of requiring assisted ventilation, 36.52 odds of hospital admission, 14.58 odds of being deceased and 4.42 odds of COVID-19-related pneumonia. The aMMP-8 mouthrinse kit was slightly more sensitive but less specific than aMMP-8 site-specific tests. Conclusions Based on the findings of the present study, periodontitis seems to be related to poorer COVID-19-related outcomes. However, within the constraints of this work, a direct causality may not be established. Periodontitis, by means of skewing the systemic condition for a number of comorbidities, may eventually influence COVID-19 outcomes in an indirect manner. Clinical relevanceThe study is the first to clinically, and by means of a validated point-of-care diagnostic methodology, assess the association between periodontal health and COVID-19-related outcomes. Assessment of the periodontal status of individuals can aid in the identification of risk groups during the pandemic along with reinforcing the need to maintain oral hygiene and seeking periodontal care.
Introduction Contemporary methods of teaching oral hygiene for the removal of dental plaque are not beneficial for visually impaired children, who depend on tactile sensations and hearing for learning. The present study was conducted to educate and motivate visually impaired children to maintain their oral health using specially designed methods that are easy for these children to understand. Additionally, the study evaluated the effectiveness of these methods over a 6‐month period. Methodology The investigation was done on 148 visually impaired children who were residents of two institutes for the visually impaired. The efficacy of a specially designed oral health education programme and two different motivational techniques utilising tactile (Group I: braille + plastic models) or auditory sensations (Group II: audio story + JAWS®, i.e. Job Access With Speech) was evaluated over 6 months based on the children's plaque and gingival scores. Results Significant improvement in mean plaque and gingival scores was evident in both the groups at the 6‐month evaluation, validating the effectiveness of both the programmes. In Group I, the mean plaque score decreased from 1.34 ± 0.29 at baseline to 1.09 ± 0.26 at 3 months, with a further decrease to 1.04 ± 0.31 at 6 months post‐implementation (P < 0.01). The mean plaque score in Group II decreased from 1.24 ± 0.47 at baseline to 1.15 ± 0.15 at 3 months (P = 0.12), and further to 1.10 ± 0.17 at 6 months (P < 0.01) post‐implementation of the educational programme. At baseline, 87.8% of the children in Group I had moderate gingivitis, whereas 52.7% of the children in Group II belonged to the mild category. At the end of 6 months, 52.7% of the children in Group I were in the mild category, and 62.2% children in Group II were in the moderate category. Conclusion Tactile and auditory measures were found to be effective in educating and motivating visually impaired children regarding maintenance of oral hygiene.
Esthetic management of extensively decayed primary maxillary anterior teeth requiring full coronal coverage restoration is usually challenging to the pediatric dentists especially in very young children. Many esthetic options have been tried over the years each having its own advantages, disadvantages and associated technical, functional or esthetic limitations. Zirconia crowns have provided a treatment alternative to address the esthetic concerns and ease of placement of extra-coronal restorations on primary anterior teeth. The present article presents a case where grossly decayed maxillary primary incisors were restored esthetically and functionally with readymade zirconia crowns (ZIRKIZ, HASS Corp; Korea). After endodontic treatment the decayed teeth were restored with zirconia crowns. Over a 30 months period, the crowns have demonstrated good retention and esthetic results. Dealing with esthetic needs in children with extensive loss of tooth structure, using Zirconia crowns would be practical and successful. The treatment described is simple and effective and represents a promising alternative for rehabilitation of decayed primary teeth.
Endodontic treatment was performed on 25 pulpally involved mandibular primary molars in 4 to 9-year-old children; the root canals were obturated with a new root canal filling material consisting of a mixture of calcium hydroxide, zinc oxide, and 10% sodium fluoride solution, using hand-operated lentulo-spirals. All cases were evaluated clinically every 3 months and also radiographically every 6 months to assess the success of the treatment; we also examined the resorption of the root canal filling material from the root canals and the status of overpushed material, if any, as the tooth resorbed with the passage of time. At 6 months, endodontic treatment in 2 of the 25 teeth had failed and one tooth had exfoliated; the remaining 22 teeth were without any signs or symptoms. At the end of 2 years, 14 teeth could be evaluated; out of these 12 had physiologically exfoliated. It was observed that the rate of resorption of this new root canal obturating mixture was quite similar to the rate of physiologic root resorption in primary teeth. In three cases, where there was an overpush of the mixture, a gradual partial resorption was noted.
Introduction Active matrix metalloproteinase (aMMP)-8 utilized in point-of-care testing (POCT) is regarded as a potential biomarker for periodontal and peri-implant diseases. Various host and microbial factors eventually influence the expression, degranulation, levels and activation of aMMP-8. The type of oral fluids (saliva, mouthrinse, gingival crevicular, and peri-implant sulcular fluids [GCF/PISF], respectively) affect the analysis. Areas covered With this background, we aimed to review here the recent studies on practical, inexpensive, noninvasive and quantitative mouthrinse and GCF/PISF chair-side POCT lateral flow aMMP-8 immunoassays (PerioSafe and ImplantSafe/ORALyzer) and how they help to detect, predict, monitor the course, treatment and prevention of periodontitis and peri-implantitis. The correlations of aMMP-8 POCT to other independent and catalytic activity assays of MMP-8 are also addressed. Expert opinion The mouthrinse aMMP-8 POCT can also detect prediabetes/diabetes and tissue destructive oral side-effects due to the head and neck cancers’ radiotherapy. Chlorhexidine and doxycycline can inhibit collagenolytic human neutrophil and GCF aMMP-8. Furthermore, by a set of case-series we demonstrate the potential of mouthrinse aMMP-8 POCT to real-time/online detect periodontitis as a potential risk disease for coronavirus disease 2019 (COVID-19). The clinical interdisciplinary utilization of aMMP-8 POCT requires additional oral, medical, and interdisciplinary studies.
With concomitant involvement of incisors, more severe presentation of MIH was seen. Also, with increase in number of affected surfaces a parallel increase in severity as well as extent of lesions was observed.
The prevalence of dental caries in 6, 9, 12 and 15-year-old school children of Chandigarh, selected on a randomized basis was evaluated using Moller's criteria (1966) and correlated with the various risk factors. The mean deft was found to be 4.0 +/- 3.6 in 6 year old and 4.61 +/- 3.14 in 9 year old, whereas the mean DMFT in 12 and 15 year old was found to be 3.03 +/- 2.52 and 3.82 +/- 2.85 respectively. The high prevalence of dental caries in these children was attributed to the lack of use of fluoride toothpaste (80% children), lack of knowledge about etiology of dental caries (98%) and frequency of sugar exposures up to more than five times per day (30%).
