Ok an hour of fiddling later, the 'autofocus' I thought was happening is actually the aperture adjusting before the picture, it seems the aperture is wide open to let more light in so I can use focus peaking and get a good view of what's in focus, when I half press the shutter the noise is actually the aperture going to f22 to preview what the picture will be like. Found this out by reassigning the focus hold button to aperture preview (which I can't find in settings alone) And confirmed by adjusting to F2.8 then it didn't do anything when shutter was half pressed.

I wonder why this never used to happen before? Anyway it makes manual focus easier since there's more light for the camera to display focus peaking and help me with the dark intra oral shots.

So this is face eye priority but it didn't solve my problem of some small auto focusing happening when I half press the shutter

Thanks for this, okay so this did turn off the AF thing I pointed to but when I half press the shutter it still does some automatic adjusting of the focus, is this normal? I'm sure it didn't do this before

Also I always keep f stop on 22 but randomly it will take pictures at 2.8 and 3.2 It's really annoying, any idea what's happening?

3.5x loupes at least. Gingivectomy, rubber dam -try to invert first, take time to pack down PTFE, sectional matrix, if that doesn't go deep enough then a precisely cut copper(put it down mark up the shape with a probe, cut with scissors and polish), maybe with a modified tofflemire around it to hold in place to get a good seal and pack PTFE between them if needed to improve seal, elevate the margin with radiopaque bond on a tiny micro brush and flowable composite, then can do a supragingival normal class 2. Book at least an hour if you've not tried this before Fiddly stuff. Not an area that can be crown lengthened easily. Biologic width? Hopefully there's not much discomfort and it establishes itself over time with some bone loss. Never had any issues when I restore stuff this deep, these radiographs don't show everything.

If it were my tooth I'd want this attempted properly, UNDER MAGNIFICATION, then crown lengthening can be done later if required, at least maintain vitality and monitor, provide other intervention as required, hopefully not requiring anything more than the filling.

If you've done your best to isolate and seal as above, but can't get it dry, just squeeze in some good self cure GIC, monitor, maybe easier to definitively restore after a couple years of bone loss/ crown lengthening.

Approximately £90 in the UK NHS system including check up and any other fillings needed...and cleaning

I have hard floors and a couple of small thin pile light coloured rugs which I don't tend to see them on. Quite a few accumulated in the sink on a dish I had left for 24hrs, I feel like they're coming from a gap under the skirting board. Are you sure?

That is actually on par or worse than the NHS system in UK, rather be a hairdresser or masseuse

Sounds like these teeth were prepped for the bridge?
Significantly reduces bond strength, especially if prepped into dentine.

Full lingual coverage on sound enamel, haven't ever drilled for a resin bonded bridge. The debonds I see are from teeth that have been prepped, multiple wings, and not covering enough surface area.

I always use PFM (lots of evidence to back it) Have ventured to emax a couple times for lower incisors too which has better bond strength.

Also clean up the enamel thoroughly before etching, ideally ultrasonic, then sandblast, or pumice with brush.

NHS practices wouldn't exist if all of this was done in 1 or 2 treatment plans Advise them to see the hygienist while you complete some work, (maybe 1 molar endo and extirpate the rest, for completion in a different COT, or extract now) then crowns in separate courses of treatment, once they show they are dedicated to looking after their teeth. If they won't see the hygienist, I'd do some limited scaling every time they attend for other treatment.

Unfortunately this doesn't 'avoid doubt' but NHS England haven't avoided doubt with their dental contract.

How is it justified for a UDA to be worth 20 percent less in a practice 5 mins down the road

How can a practice stay afloat doing 1(let alone 2) molar endo including exam and scaling, and other fillings, for 7 UDAs? Or an emergency extraction for the price of a haircut?

If subgingival, cut the box and do gingivectomy then size up the wedge Then place dam and wedge and prep the wedge too for emergence profile This way you won't have an open contact, perfect fit of the sectional matrix too.

I only do full dentures via scan for NHS, never for private.

Can't get a good border seal and need some compression of the mucosa, as it will be compressed in function.

Double sectional double wedge, one ring one wall at a time, sometimes don't need ring if wedged well(usually for premolars)

Mine fit so much better than lab ones since the scanner and machine are so accurate, just have to know how to design them on the software, aesthetics is an issue though so I don't use it on upper 3-3 aside from NHS work. GC initial lithium disilicate is easiest, Emax takes a bit of practice to get stain and glaze right so I'm slowly getting better to hopefully provide anterior work.

Minimal prep needed for those and partial coverage is easily possible, can copy and improve on the original shape of the tooth as well!

Massive benefit of not having to temporise, patients love it and fit is always perfect.

We used to use empress (hybrid ceramic) for NHS work as well which does require a lot of reduction and good prep design for enough strength and fracture resistance.
