Abstract

Background: Old adults experienced pronounced oral changes. Saliva composition particularly the antioxidantsshowed significant changes with advancing age. The aims of this study were to assess salivary antioxidants and lipidperoxidation biomarker (malondialdehyde) levels in addition to salivary physicochemical characteristics and theireffect on periodontal disease among a group of old adults in comparison with middle-aged.Materials and methods: The study group consisted of all old adults (35 subjects) aged 55-65 years in comparison withall middle-aged (35 subjects) aged 30-40 years at the Textile factory in Mosul city who fitted the criteria of the study.Periodontal disease was evaluated by using the gingival index, periodontal pocket depth and clinical attachmentlevel. Unstimulated salivary samples were collected and salivary flow rate and pH were determined. Salivary samplesthen were chemically analyzed for the detection of salivary antioxidants (total protein, albumin, vitamin E, vitamin Cand uric acid) and lipid peroxidation biomarker (malondialdehyde) in addition to salivary constituents as urea,calcium, phosphorous and magnesium.Results: Antioxidants level (total protein, albumin, vitamin E, and vitamin C) was lower among old adults comparedto middle-aged ones with significant difference for vitamin C only. Malondialdehyde was slightly higher among oldadults with no significant difference. Statistically no significant difference could be found regarding salivary flow rateand pH between the two age groups. Salivary constituents (urea, calcium, phosphorous and magnesium) showedno significant difference between the two age groups. Mean gingival index was highly significantly higher amongold adults. The extent of pocket depth was higher among old adults at ≥4 and ≥5 mm thresholds but ≥7 mm thresholdwas absent among them. Clinical attachment level extent was higher among old adults at all thresholds of severity.Salivary albumin revealed inverse significant correlation with severe thresholds of clinical attachment level (i.e. ≥7, ≥8,≥9 mm). Lipid peroxidation (malondialdehyde) showed positive highly significant correlation with ≥9 mm attachmentlevel threshold among old adults. Salivary flow rate revealed inverse correlation with almost all clinical attachmentlevel thresholds among old adults.Conclusions: Periodontal disease revealed higher severity among old adults. Salivary antioxidants andphysicochemical characteristics were found to affect periodontal health status among old adults

Abstract

Background: Old adults are regarded as an important target group with special oral health needs. Salivary glandstructure and saliva composition particularly the antioxidants are subjected to significant changes with advancingage. The aims of this study were to assess salivary antioxidants and lipid peroxidation biomarker (malondialdehyde)levels in addition to salivary physicochemical characteristics and their effect on dental caries among a group of oldadults in comparison with middle-aged.Materials and methods: The study group consisted of all old adults (35 subjects) aged 55-65 years in comparison withall middle-aged (35 subjects) aged 30-40 years at the Textile factory in Mosul city who fitted the criteria of the study.Dental caries was recorded through the application of D1-4 MFS index. Plaque and calculus indices were used forrecording oral cleanliness. Unstimulated salivary samples were collected and salivary flow rate and pH weredetermined. Salivary samples then were chemically analyzed for the detection of salivary antioxidants (total protein,albumin, vitamin E, vitamin C and uric acid) and lipid peroxidation biomarker (malondialdehyde) in addition tosalivary constituents as urea, calcium, phosphorous and magnesium.Results: Salivary antioxidants level (total protein, albumin, vitamin E, and vitamin C) was lower among old adultscompared to middle-aged ones with significant difference for vitamin C only. Malondialdehyde was slightly higheramong old adults with no significant difference. Statistically no significant difference could be found regardingsalivary flow rate and pH between the two age groups. Also salivary constituents (urea, calcium, phosphorous andmagnesium) showed no significant difference between the two age groups. Caries experience (DMFS) was highlysignificantly higher among old adults (28.71±9.15) compared with middle-aged (20.68±8.53). Multiple linear regressionanalysis revealed inverse highly significant β coefficient for vitamin E and salivary flow rate on DS among old adults.Conclusion: Dental caries revealed higher severity among old adults. Salivary antioxidants and physicochemicalcharacteristics were found to affect dental caries experience among old adults

Abstract

Background: Overweight and obesity might be a potential risk factor for periodontal diseases. The principle objectiveof this study was to identify the relationship of salivary antioxidants (vitamin E and uric acid) and lipid peroxidationbiomarker (malondialdehyde/MDA) with periodontal diseases among overweight and obese adult aged 55-65 yearoldsubject at Textile factory in Mosul city.Materials and methods: All subjects aged 55-65 year-old (thirty five subjects) at Textile factory in Mosul city took partin this study. Salivary flow rate was measured after collection of unstimulated saliva then salivary samples wereanalyzed for the measurement of salivary antioxidants (vitamin E and uric acid) and lipid peroxidation biomarker(malondialdehyde/MDA). Periodontal diseases were evaluated by using the gingival index (GI), periodontal pocketdepth (PPD) and clinical attachment level (CAL). Body weight was determined by using the Body Mass Index (BMI).Results: Malondialdehyde (MDA) level was higher among obese and overweight than non-obese with highlysignificant difference (F=5.52, P<0.01). Similarly vitamin E and uric acid levels were elevated among obese andoverweight compared with non-obese though statistical differences were not significant (P>0.05). In contrast salivaryflow rate was lower among obese and overweight than non-obese with highly significant difference (F=8.11, P<0.01).Regarding periodontal diseases, obese subjects showed higher periodontal destruction in comparison with nonobese.Conclusions: Overweight and obese subjects could be considered as special group who need educational andpreventive programs that include maintaining a normal body weight, eating a well-balanced diet and engaging inphysical activity in addition to oral hygiene practices to improve their oral and general health.

Abstract

Background: Overweight and obese people are at higher risk for systemic diseases as well as oral diseases like dentalcaries. The aim of this study was to explore the relationship of salivary antioxidants (albumin, vitamin E, and vitamin C)in addition to salivary flow rate and magnesium level with dental caries severity among overweight and obese adultaged 30-40 year-old at Textile Factory in Mosul City.Material and method: The sample for this study consisted of all subjects aged 30-40 year-old (thirty five subjects) atthe Textile factory in Mosul city. Body weight can be measured by using the Body Mass Index (BMI). Dental caries wasrecorded by lesion severity through the application of D1-4 MFS index. Salivary flow rate was measured after collectionof unstimulated saliva then salivary samples were analyzed for the measurement of salivary antioxidants (albumin,vitamin E, and vitamin C) and magnesium level.Results: Salivary vitamin E and C levels were higher among overweight and obese subjects respectively comparedwith non-obese though statistical differences were not significant. Albumin level was significantly higher amongoverweight than non-obese subjects. In addition Obese and overweight subjects revealed reduced salivary flow ratecompared with non-obese but with no significant difference; whereas salivary magnesium level was elevatedamong obese compared to non-obese individuals though statistical difference was not significant. Regarding cariesseverity, obese and overweight subjects revealed higher dental caries severity (i.e. DMFS, MS, DS, D3 and D4 meanvalues) compared with non-obese.Conclusions: Overweight and obesity could be risk factor for increasing dental caries severity thus educational andpreventive programs that include dietary counseling (for lowering body weight and caries severity as well), oralhygiene practices, and regular visits for the dentist are needed
