Palato-Radicular Groove: A Rare Entity in Maxillary Central Incisor Leading To Endo-Perio Lesion

<p>Treatment of an Endo-Perio Lesion with Ozone Gas in a Patient with Aggressive Periodontitis: A Clinical Case Report and Literature Review</p>

“…2-month RVG showed stabilization of the radiolucent image. 12-month (6 months after open flap) showed partial healing of bone radiolucency, 18-months RVG showed decreasing of radiolucency, 39-month RVG showed disappearing of former radiolucency Aksel and Serper, 2014 16 Healthy 42 #37 PPSE Negative Severe bone loss around the distal root of tooth #37 related to the uncleaning space between second and third molar Not reported Not reported Involved No RCT, extraction of third molar 6 month recall visit, the complete repair of the bony lesion; 1 year recall radiograph showing complete healing of the bone lesion Makino-Oi et al, 2017 40 Not reported 60 #16, 27 PPSE Negative Periapical radiolucency suggested perio-endo lesion 7–9 mm Yes Grade I–II No No treatment was done, teeth were extracted because of poor prognosis (furcation involvement and mobility) - Nadig et al, 2016 42 Not reported 35 #11 PPSE (radicular groove) Not reported Extensive peri-radicular radiolucency involving the apical and middle one-third of the mesial aspect of root 13 mm Not reported - No SRP, RCT, calcium hydroxide for 3 weeks, obturation, 8 weeks later radicularplasty, periodontal surgery with grafting and PRF 1-year follow-up RVG significant reduction in radiolucency around the root surface Gandhi et al, 2011 43 Not reported 30 #22 PPSE (radicular groove) Not reported Showed an accessory ...…”

“…In the PPSE lesion group, four single-rooted teeth were splinted 35 , 46 (the diabetic patient was not counted) and two were not; 35 , 42 over long-term periods, they had comparable results. In the present case, splinting was done before endodontic treatment, which contributed to the complete healing of the lesion in 6 months.…”

“…In patients with PPSE lesions with palatal radicular grooves, 42 – 45 the mean age was 26.5 years (minimum 19 and maximum 35). The mean age of patients with PPSE without radicular grooves was 48 years (minimum 40 and maximum 60), 10 ,– 16 ,– 35 ,– 39 – 46 considering patients with aggressive periodontitis 10 , 41 were not counted.…”

“…Two cases with palatal radicular grooves 42 , 44 had comparable baseline parameters and underwent endodontic therapy, SRP, and periodontal regenerative surgery. One 44 showed complete healing at a 6-month follow-up, and the other 42 demonstrated reduced radiolucency at a 1-year follow-up. Two cases without regenerative surgery 43 , 45 showed reduced radiolucency at 6-month and 1-year RVG follow-ups.…”

“…There were 18 teeth with PPSE (six molars 10,-16,-39-41 and 12 single-rooted teeth 35,[42][43][44][45][46] ) in the reviewed literature. Two molars were extracted without any treatment.…”
