Maintain or Extract? First Permanent Molars of Poor Prognosis - PDP279
Your patient is nine years old. One first permanent molar is crumbling — the others look fine. Does it stay, or does it go?Is that broken-down first permanent molar really down to poor brushing — or is it Molar Incisor Hypomineralisation?When is the right time to take a first permanent molar out — and how do you read it off the X-ray?And how do you tell a parent their child needs an adult tooth removed — without losing them?First permanent molars of poor prognosis are one of the genuine head-scratchers of general practice — full of ifs, buts and timing. In this episode Jaz sits down with Dr Nicole Sturzenbaum, a paediatric dentist and the owner and clinical director of Toothbeary in Richmond, London, to work through the whole decision: getting the diagnosis right (molar-incisor hypomineralisation versus caries), reading the extraction window off an OPG, the restorative ladder from sealant to stainless steel crown, when to bring in the orthodontist, and how to handle the conversation with anxious parents. There’s no one-size-fits-all answer — but there is a clear way to think about it.Protrusive Dental Pearl: Painless Polishing for Anxious KidsThe mechanical clean is what frightens children (and plenty of adults) — the scaler, the bristle brush, the gritty prophy paste. For the polishing part, a colourless plaque-dissolving foam gel does the job without any of it. It fizzes wherever there is plaque, so you can hand the child a mirror and show them exactly where to brush; it leaves the teeth satin-smooth, reduces gingival inflammation, and is painless and non-invasive.Two caveats: it does not remove calculus — you still need a hand or ultrasonic scaler for that — and you should agitate the gel gently at the gingival margin for the full effect. It is especially useful for orthodontic and adolescent patients because it reaches the nooks around brackets, which is where post-orthodontic white-spot lesions start.Product: Magic3 (3% hydrogen peroxide, colourless plaque indicator), by Dr Wyman Chan — protrusive.co.uk/magic3.What You’ll Take From This EpisodeDiagnosis first — MIH or caries? The distinction changes the plan, the prognosis and the whole conversation with the family.Reading the extraction window off an OPG — why chronological age tells you nothing, and what the second molar’s bifurcation tells you instead.The restorative ladder — seal, composite, preformed metal crown, or plan the extraction: matching the least invasive option that will actually hold.When to involve the orthodontist — essential or desirable, which teeth come out, and managing the space afterwards.Getting sensitive molars numb — why MIH teeth are so hard to anaesthetise, and the comfort stack that helps.Highlights of This Episode00:00 TEASER00:59 First Permanent Molars of Poor Prognosis in Children02:51 Painless Chemical Polishing for Kids (Protrusive Dental Pearl)04:53 Meet Dr Nicole Sturzenbaum, Paediatric Dentist11:49 MIH or Caries?
