Coronectomy of partially erupted lower third molars performed by an undergraduate dentistry student: a case series

Does the Coronectomy a Feasible and Safe Procedure to Avoid the Inferior Alveolar Nerve Injury during Third Molars Extractions? A Systematic Review

“…The extracted data from the studies’ compilation are presented precisely in Table 2 . In total, sixteen articles were included: nine PS (Agbaje et al [ 19 ]; Cilasun et al [ 6 ]; Kang et al [ 20 ]; Kowenberg et al [ 3 ]; Leung et al [ 21 ]; Leung et al [ 22 ]; Mendes et al [ 23 ]; Monaco et al [ 24 ]; and Pedersen et al [ 25 ]), four RS (Mukherjee et al [ 26 ]; Frenkel et al [ 2 ]; Kohara et al [ 27 ]; Pogrel et al [ 13 ]), a single study of case-control (Hatano et al [ 28 ]) and two RCTs included studies (Leung et al [ 8 ]; Renton et al [ 29 ]).…”

“…Eight authors (Frenkel et al [ 2 ], Hatano et al [ 28 ], Kohara et al [ 27 ], Leung et al [ 8 ], Leung et al [ 22 ], Leung et al [ 21 ], Mendes et al [ 23 ] and Pedersen et al [ 25 ]) reported the occurrence of IAN damage post coronectomy procedure. Mendes et al [ 23 ] presented 2.85% (one case) and Pedersen et al [ 25 ] 2.16% (five cases) differently to the average, which was 0.59%. All the other articles cited that no patient experienced numbness, swelling or a thickening sensation of the lower lips after surgery after the procedure.…”

“…Four articles (Frenkel et al [ 2 ], Kang et al [ 20 ], Kohara et al [ 27 ], and Mendes et al [ 23 ]) provided no records or insufficient data concerning the sensitivity of the lingual nerve postsurgical procedures.…”

“…The high incidence (more than 80% of their cases) of root migration was reported in Kang et al [ 20 ]; Hatano et al [ 28 ]; Kohara et al [ 27 ]; Kouwenberg et al [ 3 ]; Mendes et al [ 23 ]. Coronal migration of the roots was reported as the most commonly reported long-term consequence of coronectomy, which is confirmed by our review.…”

“…The onset of pain was evaluated in eleven of the included articles (Agbaje et al [ 19 ]; Cilasun et al [ 6 ]; Frenkel et al [ 2 ]; Hatano et al [ 28 ]; Leung et al [ 8 ]; Leung et al [ 22 ]; Leung et al [ 21 ]; Mendes et al [ 23 ]; Mukherjee et al [ 26 ]; Pedersen et al [ 25 ]; Renton et al [ 29 ]).…”
