RELIABILITY OF FLUORESCENT CAMERA VERSUS VISUAL ASSESSMENT IN DIAGNOSIS OF OCCUSAL CARIOUS LESION IN ADULT PATIENTS: INVIVO DIAGNOSTIC STUDY

Bohler angle and the crucial angle of Gissane are used on the evaluation of calcaneus fractures. However, few authors have described the variation of the angles when the calcaneus is growing. In this study, Bohler angle and the crucial angle of Gissane in paediatric population were measured using lateral foot radiographs of 429 patients, from 0 to 16 years of age. The control group was composed of 70 adult patients. The sample had a mean Bohler angle of 35.4° ± 5.9° and a mean crucial angle of Gissane of 110.5° ± 7.4°. The greater mean difference was identified for Bohler angle (8°) in the age group of 5 to 8 years (39.6° ± 5.7°) and for the crucial angle of Gissane (5°-6°) in the age group of 0 to 4 years (115.8° ± 7.3) ( P < .05). The influence of the ossification centres on the geometry of the calcaneus across age groups makes Bohler angle and the crucial angle of Gissane higher in young children. The increase in Bohler angle points out the relative development of the posterior facet in young children and the importance of the reconstruction of the posterior facet height in the intra-articular calcaneus fractures.

Abstract Introduction With the increasing prevalence of obesity, the diagnosis of obstructive sleep apnea (OSA) and obesity hypoventilation syndrome (OHS) have also increased. Adding routine transcutaneous carbon dioxide (TcCO2) or end-tidal carbon dioxide sensors (EtCO2) may add beneficial information to the polysomnogram (PSG) and expand the diagnostic and treatment capabilities in this population. Our study looks at the use of this parameter in obese adults on whom CO2monitoring has been used. Methods We performed a retrospective chart review of obese adult patients (body mass index [BMI] >30) undergoing a PSG. We documented the EtCO2 values at baseline (supine awake) and during sleep. Correlations between the EtCO2 readings and BMI were reviewed. We excluded patients that had poor EtCO2 waveforms and patients with known preexisting hypoventilation syndromes, such a COPD. Results Fifty patients were identified between January and November 2020 at the Memorial Hermann Sleep Center. 54% were female and 46% were male with an average age of 55.3 years (range 26–73) and an average BMI for the cohort of 40.1 (SD +/-9.5). The average AHI on the diagnostic study (CMS criteria) was 30.9 events/hour (SD +/- 43) and the average oxygen desaturation nadir was 79%. Sixteen patients (32%) met diagnostic criteria for OHS based on the baseline awake EtCO2 which would have otherwise been missed without CO2 monitoring. When comparing the mean values of the ETCO2 between Group 1 whose BMI was less than 40 kg/m2 (39.9 mmHg) to Group 2 whose BMI was greater than 40 kg/m2 (45.9 mm Hg), the difference was statistically significant with a p-value is 0.001. Conclusion OHS is reported to have greater mortality when compared to OSA. CO2 monitoring is currently only routinely required in pediatric PSGs. Our review suggests a higher diagnostic yield of OHS in adults with the use of CO2 monitoring especially when morbidly obese. Given the alarming trend towards obesity in the US, this advocates for the routine use of CO2 monitoring in adult obese patients. Although more research is needed, we may draw a conclusion that there is meaningful data to support the use of routine ETCO2 monitoring in this adult patient population. Support (if any):

Background: Application of caries assessment spectrum and treatment (CAST) instrument for staging and evaluating treatment needs of an adult population suffering from dental carious lesionObjectives: Study was conducted with aim of applying CAST instrument for staging adult urban Indian population according to severity of carious lesion and treatment needs required.Methods: Cross-sectional descriptive study was conducted on 300 adult patients. After training session and calibration of examiner, all patients were examined for the caries experience and CAST codes were recorded on a structured proforma.Results: Of 300 adult patients, 18% (54) adults have healthy dentition denoted by codes 0,1, and 2. 12 % and 15.3% adults were in reversible premorbidity stage (code 3) and morbidity stage (codes 4 and 5) respectively. The largest number of adults 29.7% were seen in serious morbidity stage (codes 6 and 7) followed by 21.3% adults in mortality stage (code 8) requiring either root canal treatment or extraction and replacement of teeth as treatment needs.Conclusion: CAST instrument has been found useful in staging adult population suffering with dental carious lesion and evaluating their treatment needs. Moreover, CAST is easy to apply for staging the carious lesion due its hierarchical structure and reporting results in an understandable manner.Keywords: Adults; Caries Assessment Spectrum and Treatment; Dental Caries; Treatment needs.
