Amaç: Bu çalışmada çocukların günlük diyet potansiyel renal asit yükü (Potential Renal Acid Load: PRAL) değerinin hesaplanarak karyojenik ve koruyucu rolü olan besinlerin bir arada değerlendirilmesi ve tükürük pH'ı ve ağız sağlığı ile ilişkisinin incelenmesi amaçlanmıştır. Bireyler ve Yöntem: Araştırma 12 yaş, 96 kız ve 92 erkek olmak üzere toplam 188 sağlıklı çocuk üzerinde yürütülmüştür. Çocukların tükürük örnekleri yaklaşık aynı saat aralıklarında ana öğünden en az 2 saat sonra ve aynı ortamda alınmıştır. Toplanan tükürüğün tamponlama kapasitesi düşük (pH6) olarak değerlendirilmiştir. Tükürük örneği alınmadan bir gün önce 24 saatlik besin tüketim kaydı alınmış ve diyet asiditesinin değerlendirilmesi için diyet PRAL değeri hesaplanmıştır. Diyet PRAL değerinin eksi (-) ve giderek küçülmesi diyetin alkaliye kaydığını gösterirken artı (+) yönde artması ise diyetin asiditeye kaydığını göstermektedir. Çocukların ağız muayeneleri diş hekimi tarafından yapılmıştır. Çürük, kayıp ve dolgulu kalıcı diş (DMFT) ve süt diş (dmft) sayıları ile diş yüzeylerinin toplamı (DMFS-dmfs) indeksleri hesaplanmıştır. Bulgular: Çocukların %48.3'ünün kalıcı dişlerinde en az bir diş çürüğü, %34.4'ünün ise en az bir dolgusu olduğu saptanmıştır. Çocukların %66.1'inin tükürük tamponlama kapasitesi düşük ve toplam çürük sayısı tükürük tamponlama kapasitesi ile ilişkili olduğu bulunmuştur (p
Aim: This study aimed to evaluate the relationship between diet PRAL value and saliva pH and oral health by considering the cariogenic and protective effects of foods in children. Subjects and Method: The study was conducted on 188 healthy children (96 girls and 92 boys aged 12). Salivary sample of children was taken at least two hour after main meal. Salivary buffer capacity was evaluated as low (pH<4), normal and high (pH>6). The 24-hour food records were taken one day before the salivary sample collection and diet PRAL was calculated for evaluation of dietary acidity. Negative values and/or decrease in PRAL meant a shift to an alkaline level whereas a positive and/or increase in PRAL was considered as a shift in acidic level. Oral examination was performed by a dentist. Number of decay, missed and filled in permanent tooth (DMFT) and in primary tooth (dmft) and tooth surface (DMFS-dmfs) were calculated. Results: 48.3% of children have at least one tooth decay and 34.4% of children have at least one filled tooth. 66.1% of children have low buffer capacity and total decayed teeth are positively correlated with buffer capacity pH (p<0.05). Dietary PRAL was negatively correlated with vegetable and fruit consumption (p <0.01). There was no significant difference between PRAL values of children with or without decayed teeth (p>0.05). Furthermore dietary PRAL value was only positively correlated with the number of milk tooth fillings (p<0.05). Conclusion: Diet PRAL value is affected by variety of food groups therefore it can effect oral health. Increasing vegetables and fruit consumption in children nutrition so decreasing diet PRAL value provide more alkaline nutrition and this is effective for oral health protection.
