Management of an Immature Necrotic Permanent Molar with Apical Periodontitis Treated by Regenerative Endodontic Protocol Using Calcium Hydroxide and MM-MTA: A Case Report with Two Years Follow Up

Abstract: Traditionally, immature teeth diagnosed with necrotic pulp and periapical periodontitis were treated by apexification with long-term calcium hydroxide or in one session with mineral trioxide aggregate (MTA) or Biodentine apical plug. However, these teeth become fragile and susceptible to root fracture. Regenerative endodontic procedure is a new therapeutic approach that promotes continuation of root growth in immature necrotic teeth potentially preventing root fracture. Only few case reports have shown the suc… Show more

“…Among the included studies, six studies illustrated negative outcomes in regard to endodontic regeneration therapy in the management of immature necrotic permanent teeth [ 29 , 34 , 46 , 48 , 49 , 54 ]. On the other hand, 40 studies showed significant positive outcomes for endodontic regeneration treatment in these kinds of teeth due to root development, root wall thickening, root lengthening, and formation of hard tissue barrier or apical closure [ 3 , 4 , 6 , 16 , 20 , 22 , 26 28 , 30 – 33 , 35 45 , 47 , 50 53 , 55 – 65 ]. The outcomes of these 46 studies include different types of intracanal medications, scaffolds, pulpal space/barrier, root maturation stage, follow-up duration, and updating studies on their effect in periapical periodontitis and periapical healing.…”

“…6,14 Furthermore, in the case of performing apexification procedures, proper root development cannot be achieved, and the tooth may be more susceptible to fracturing. 15 Previous studies have reported numerous minimally invasive caries removal methods with the purpose of reducing noise, vibration, fear, excessive removal of uninfected dentine, and pain. 14,[16][17][18] For example, carbon steel, tungsten carbide, or polymer burs, hand instruments (excavators, chisels), air abrasion, air polishing, ultrasonics, sono-abrasion, CMCR agents, lasers, photo-active disinfection (PAD), or ozone were used for selective caries removal.…”

“…The 18 included studies had a total sample of 250 successful cases of RET. 13,[28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44] The types of studies included in this systematic review were as follows: 7 case reports/case series 28,30,[35][36][37]41,44 ; 3 prospective studies 33,39,43 ; 5 retrospective studies 31,32,34,38,40 ; and 3 randomized clinical trials (RCTs). 13,29,42 The number of successful RET cases ranged from 1 to 45, with the total number of 250.…”

“…Preoperatively, all of the 250 successful cases of RET included across the 18 studies illustrated pretreatment radiographic evidence of periapical pathology. 13,[28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44] Postoperatively, clinical signs indicative of infection (pain, swelling and the sinus tract) were absent from 239 (96%) of the RET cases. There was a trend toward a reduction in the size of periapical pathology early after the initiation of RET (reported at less than 1 year) and the complete absence of periapical pathology after at least 2.5 years (Table 3).…”
