Yr adroddiad gan Iechyd Cyhoeddus Cymru yw'r arolwg deintyddol diweddaraf o blant pum mlwydd oed yng Nghymru, a chafodd ei gynnal gan Uned Gwybodaeth Iechyd Geneuol Cymru, fel rhan o raglen arolwg deintyddol y Gwasanaeth Iechyd Gwladol (GIG).  
  
Mae'r adroddiad yn dangos:  
  


* gostyngiad yng nghyfran y plant â phydredd dannedd rhwng 2007\-08 (47\.6%) a 2015\-16 (34\.2%). Mae hyn yn dangos bod y gyfran o blant nad oes ganddynt bydredd dannedd amlwg erbyn eu bod yn 5 mlwydd oed yn parhau i wella. Yn 2015\-16 bydd 20 o blant mewn dosbarth o 30 heb gael unrhyw brofiad o bydredd dannedd. Mae hyn yn cymharu ag 16 o blant mewn dosbarth o 30 heb unrhyw bydredd dannedd yn 2007\-08;
* mae profiad o bydredd dannedd cymedrig Cymru gyfan (dannedd wedi pydru a gollwyd ac a lenwyd \- (dmft)) hefyd wedi parhau i syrthio o 1\.98 yn 2007\-08 i 1\.22 yn 2015\-16\. Mae hyn yn ostyngiad o 38% yn y sgorau dmft cymedrig dros 9 mlynedd;
* yn 2007\-08, byddai 14 o blant mewn dosbarth o 30 wedi cael profiad o bydredd, a byddai 4\.2 dant wedi cael ei effeithio ar gyfartaledd. Erbyn 2015\-16 roedd hwn wedi syrthio i 10 o blant mewn dosbarth o 30, sef cyfartaledd o 3\.6 dant wedi pydru;
* mae lefelau clefydau deintyddol ymhlith plant yng Nghymru yn dal i wella ar draws bob grŵp cymdeithasol. Mewn termau absoliwt, y cwintel mwyaf difreintiedig sydd wedi gweld y gostyngiad mwyaf mewn achosion o bydredd dannedd (o 15%) ac o ran sgôr dmft gymedrig (o 0\.6\). Nid oes unrhyw dystiolaeth bod anghydraddoldeb yn cynyddu.

Dywedodd Vaughan Gething, yr Ysgrifennydd Iechyd:  

> “Dw i'n falch o weld y cynnydd sy'n parhau i wella iechyd y geg ymhlith plant. Mae'n glir bod y rhaglen Cynllun Gwên yn gwneud gwahaniaeth go iawn i wella iechyd y geg ymhlith plant ledled Cymru ond rydyn ni'n gwybod bod angen inni barhau i wneud y gwelliannau hyn.
> 
> “Fel llywodraeth, rydyn ni wedi ymrwymo'n llawn i daclo pob math o anghydraddoldeb. Dw i'n arbennig o falch felly mai plant o'r cefndiroedd mwyaf difreintiedig sy’n gweld y gostyngiad mwyaf mewn pydredd dannedd.”

Dywedodd Dr Colette Bridgeman, Prif Swyddog Deintyddol Cymru:


> “Er ein bod ni wedi gweld gwelliannau mawr o ran pydredd dannedd ymhlith plant blwyddyn ysgol 1 dros y degawd diwethaf, mae yna botensial i wella ymhellach ar gyfer y traean o blant sy'n dal i brofi pydredd dannedd.
> 
> “Rydyn ni'n gwybod bod pydredd dannedd yn dechrau'n gynnar. Fel arfer, bydd hanner y pydredd dannedd y mae plant yn ei brofi yn 5 oed i'w weld yn 3 oed. Bydd mwy o effaith yn dod o ymyrryd yn gyntaf cyn bod y plentyn yn 3 oed. Rydyn ni'n rhoi ffocws newydd felly i'r Cynllun Gwên ar y grŵp oedran 0\-5 oed, er mwyn sicrhau bod plant yn parhau heb unrhyw bydredd dannedd yn 5 oed.  Bydd hyn yn ein helpu i wneud y gwelliannau pellach sy’n angenrheidiol."

The report by Public Health Wales is the latest dental survey of five\-year\-old children in Wales, undertaken by the Welsh Oral Health Information Unit, as part of the NHS dental survey programme.  
  
The report shows:  
  
* a reduction in the proportion of children with decay between 2007\-08 (47\.6%) and 2015\-16 (34\.2%). This represents continuing improvement of the proportion of children who have no obvious decay experience by age 5\. In 2015\-16 in a class of 30 children 20 will have no decay experience. This compares with 16 decay free in a class of 30 children in 2007\-08;
* the all\-Wales mean decay experience (decayed missing and filled teeth \- dmft) has also continued to reduce from 1\.98 in 2007\-08 to 1\.22 in 2015\-16\. This represents a 38% reduction in mean dmft scores in 9 years.
* in 2007\-08, 14 children out of a class size of 30 would have decay experience, with an average of 4\.2 teeth affected. By 2015\-16 this had fallen to 10 children out of a class of 30, with an average of 3\.6 decayed teeth;
* dental disease levels in children in Wales continue to improve across all social groups. In absolute terms, the most deprived quintile have seen the largest reduction in decay prevalence (by 15%) and mean dmft score (by 0\.6\). There is no evidence of widening inequalities.

Health Secretary Vaughan Gething said:  
  

> “I’m pleased to see the continued progress in improving children’s oral health. It’s clear that our Designed to Smile programme is making a real impact in improving the oral health of children across Wales but we know that we have to continue seeing these improvements.  
>   
> “As a government, we are fully committed to tackling all forms of inequality So I’m particularly pleased to see that children from the most deprived backgrounds are seeing the biggest reduction in tooth decay.”

  
Chief Dental Officer for Wales, Dr Colette Bridgeman said:  
  

> “Although we’ve seen great improvements in tooth decay in school year 1 children over the last decade or so, there is scope for further improvement for the third of children still experiencing tooth decay.  
>    
> “We know that dental decay starts early. Typically, half of the decay experienced at 5 years of age will be evident by age 3\. Therefore, primary intervention will have most impact before the age of 3, so we are re\-focussing Designed to Smile on the 0\-5 age group, restating the overarching aim of the programme, to keep children decay free by the age of 5\. This will help us deliver the further improvement we need.”
